The shift from brushed to brushless motors,the proliferation of LEDs to replace the filament-type light bulbs in lightings,the increasing use of DC motors to improve fuel efficiency,the adoption of more IA(artificial intelligence)technology in driver assistance (e.g.blind-spot warning,lane departure warning,lane keeping assist,adaptive cruise control,etc.)result in the use of more and more power semiconductor components in vehicles.In alignment to the mega trend of electrification of transportation mobility,JJM has been offering more and more automotive-grade components to E-mobility (battery storage,renewable energy source,electric propulsion)accent exterior lightings,ADAS (advanced driver assistant systems),vehicle-to-vehicle communications cybersecurity,telematics and infotainment,etc.

In the auto-grade MOSFETs which bear 'Q'as the last letter in the product name,the die is designed with key performance matrices {ON-resistance RDS(ON),input capacitance CISS,total gate charge Qg}minimized and SOA(safe operating area)further optimized.Assembled in the thermally efficient low-profile packages like the TOLL-compatible PowerJER10x12 and PDFN5x6-8L with long protruded lead pins,these auto-grade MOSFETs offer world-class power efficiency,lower operating temperature,exceptional long-term reliability despite of the hostile working environment typical inside and outside of automobiles.At JJM,the auto-grade diodes(TVS, ESD,rectifier,zener,etc.)are constructed with the patented clip assembly process.Compared to the traditional A+B structure,the risk of cold joint is minimized,thermal and physical stress on the die surface are minimized. All these result in outstanding long-term component reliability.Long-standing and reliable protection to prevent the semiconductor devices (application processor,mixed-signal interface IC,etc.)used in key sub-systems like power and traction inverter from damage by spurious electrical surges and other hazard are achieved.These auto-grade diodes offer world-class electrical performance like clamping voltage tailored to specific application requirement,low leakage current,and fast response as well as compliance to AEC-Q101-Rev-E stress test standards

Auto-grade power semiconductor components (MOSFET,TVS)from JJM are being extensively applied to motor driving in the many sub-systems in automobiles:EPS (electronic power steering),oil pumps,water pumps, power windows,rear trunk hatch,power seats,power sunroots,etc.

Auto-grade MOSFETs offer outstanding performance matrices {ON-resistance RDS(ON),input capacitance CISS,total gate charge Qg)with the SOA(safe operating area)further optimized.Assembled in the thermally efficient low-profile packages like the TOLL-compatible PowerJER10x12 and PDFN5x6-8L with long protruded lead pins,these power-efficient auto-grade MOSFETs are widely applied in various applications inside automobiles.The long-term reliability are ensured by their compliance to the AEC-Q101-Rev-E stress test standards

Assembled in the patented DO-218 package of JJM,the auto-grade TVS(transient voltage suppressor)can be applied to both 12VDC and 24VDC systems.They were tested to pass ISO 16750-2 P5a/5b compliant load- dump test and off PPP_Max performance of 4.6~8.0kW.Besides the ability to perform consistently across all key electrical matrices,these TVS also offer high surge immunity and exceptional long-term operating reliability. Hence,these auto-grade TVS are field-proven to be indispensable for the protection of valuable electronic sub- systems inside automobiles.

Auto-grade power semiconductor components (MOSFET,TVS)from JJM are being extensively applied to power sourcing applications (accent lights,head lamps,included)in automobiles.

Partly attributed by the advanced wafer process,the auto-grade MOSFETs offer excellent electrica characteristics such as RDS(ON)and Qg.The resultant low switching and conduction loss significantly reduce operating temperature hence they are good fit for the power conversion circuits running at high frequency to minimize BOM(bill of materials)space.The portfolio of auto-grade MOSFETs currently cover VDS_Max from 40 ~150V(medium-voltage category).Future releases shall be extended all the way to 650V and higher.

The auto-grade TVS are assembled with the patented clip assembly process.Compared to the traditional A+B structure,the risk of cold joint is minimized,thermal and physical stress on the die surface are minimized,high degree of long-term operating reliability are resulted.On top,the excellent voltage clamping ability,low leakage current and fast response are typical of these auto-grade TVS.Compliance to the AEC-Q101-Rev-E stress test standards provide another further warranty to trustable operation.

Auto-grade power semiconductor components (MOSFET,TVS)from JJM manifest unique benefits to battery management system whose behavior is critical to NEVs(new energy vehicles).

JJM offers auto-grade MOSFETs with ON-resistance as low as 0.58m which contribute to lower operating temperature.Assembled in state-of-the-art packaging process,the resulted power discrete component perfectly customer demands for the often conflicting requirement of high power and low heat dissipation.To name a few, auto-grade MOSFETs housed in the PDFN5x6-8L,PowerJER7x8(compatible with sTOLL),PowerJER10 x12 (compatible with TOLL)offer some of the best class-leading performance in the industry.In addition,these components undergo the rigorous AEC-Q101-REV-E compliant stress tests,hence they are field proven to meet the challenge of harsh operating conditions typical of automobiles.

The auto-grade TVS are manufactured with the patented clip assembly process.As opposed to the traditional A+B assembly,cold joint is minimized,die stress is much reduced,outstanding long-term reliability is achieved. These components achieve excellent peak pulse power PPP_Max at 1.0kW and more in the minuscule SMB package size.Both uni-directional and bi-directional types of protection capabilities are available.Overall,the excellent electrical performance,the outstanding voltage clamping ability,the low leakage current,the fast response to incoming spurious voltage surges,and the compliance to AEC-Q101-Rev-E stress test standards make these auto-grade TVS from JJM a perfect answer to the ever demanding safety and reliability requirement upon the tens of millions of vehicles purchased by consumers nowadays.
