High-Voltage Surface-Mount Diode for Automotive Applications Release

Nov. 28, 2025

~ Achieves surface mounting for a withstand voltage over 1,000 V, balancing a high voltage rating and miniaturization ~

Shindengen Electric Manufacturing Co., Ltd. is adding new products to its high-voltage surface-mount CG Package lineup, designed for automotive applications.

In recent years, as inverters in automotive and industrial equipment become smaller and more advanced, demand has grown for compact, high-voltage surface-mount diodes.
Achieving high withstand voltages requires sufficient terminal spacing, but space constraints in surface-mount packages make securing adequate insulation distance difficult.Specifically, international standards recommend a terminal spacing of 5.6 mm or more for voltages exceeding 1,000 V, and meeting this requirement necessitates innovative package design.

High-voltage surface-mount package "CG package"

To address these needs, Shindengen Electric Manufacturing has added two new models to its already mass-produced high-voltage surface-mount CG Packages that can also be used in automotive applications.
The CG Package ensures insulation performance compliant with the international standard IEC 60664-1 by extending the terminal spacing to 5.6 mm.This enables it to handle high-voltage circuits exceeding 1,000 V effective voltage even in Pollution Degree 2 environments. While through-hole packages have traditionally dominated high-voltage applications, this package enables high-voltage capability via surface mount technology.
The newly added automotive-grade variants comply with AEC-Q101, meeting the high reliability and stable operation under high-temperature conditions required for automotive equipment.This contributes to the high-voltage capability and miniaturization of inverters in the automotive and industrial equipment sectors.

■ Features
