High-Voltage Zeners Target Automotive ECUs

ROHM has announced the development of high-voltage Zener diodes optimized for protection and constant current applications in a variety of electronic circuits. The UDZLV and KDZLV series are comprised of 12 models in Zener voltages ranging from 51V to 150V. They are also AEC-Q101 compliant and provide superior surge resistance for greater reliability, making them suitable not only for automotive ECUs, but industrial and consumer applications as well.

Until now, ROHM has offered a popular lineup of low-voltage (2V to 47V) Zener diodes designed for power supplies in smartphones and portable devices. However, with the increased focus on the automotive and industrial sectors in recent years comes a need to strengthen the company’s portfolio of power products, including resistors, transistors and diodes.

In response, ROHM has expanded their lineup of UDZV diodes to include the high-voltage UDZLV series, which features a rated power of 0.2W in a compact 2.5mm x 1.2mm sized package, making it suitable for consumer electronics as well as automotive ECUs, MFPs, and inkjet printers. ROHM also developed the KDZLV series of high voltage 1.0W rated Zener diodes for automotive and industrial applications, available in a 3.5mm x 1.6mm form factor.

The UDZLV series is available now with pricing starting from $0.046 /unit (1,000pcs). The KDZLV series is also available immediately with pricing from $0.128 /unit (1,000pcs).
