HV Zeners withstand surges in automotive ECUs

December 19, 2016 // By Graham Prophet
Rohm Semiconductor has added high voltage Zener diodes optimized for protection and constant current applications. The UDZLV and KDZLV series comprise 12 models in Zener voltages ranging from 51V to 150V. They are AEC-Q101 compliant and provide superior surge resistance for greater reliability in automotive ECUs, industrial and consumer applications.

ROHM has previously offered a popular lineup of low-voltage (2V to 47V) Zener diodes; these introductions respond to an increased focus on automotive and industrial sectors. The expanded lineup of UDZV diodes includes the high-voltage UDZLV series, which features a rated power of 0.2W in a 2.5 x 1.2 mm sized package, making it suitable for consumer electronics as well as automotive ECUs, MFPs, and inkjet printers. The KDZLV series of high voltage 1.0W rated Zener diodes for automotive and industrial applications is available in a 3.5 x 1.6 mm form factor.
