ROHM's New High Voltage Zener Diode Lineup

KYOTO, JAPAN and SANTA CLARA, CA--(Marketwired - December 15, 2016) - 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.

Zener diodes are used in a wide variety of applications, primarily to maintain a constant voltage even when abnormally large currents temporarily flow through the circuit in order to prevent damage to electronic equipment. And the demand for Zener diodes is expected to only grow as the trend in the automotive and industrial industries continues towards greater computerization.

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 our portfolio of power products, including resistors, transistors and diodes.

In response, we have expanded our 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. We have 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.

UDZLV series
Availability: Now
Pricing: Starting from $0.046 /unit (1,000pcs)

KDZLV series
Availability: Now
Pricing: Starting from $0.128 /unit (1,000pcs)

Key Features

1. Broad lineup supports a wide range of applications

2. Low noise with high surge immunity

Both the UDZLV and KDZLV series utilize material and process optimization to ensure high surge immunity while maintaining low noise characteristics. Their superior surge resistance makes them ideal for not only consumer applications, but industrial equipment and automotive systems as well that demand increased reliability.
