GL34G/1

Single Diodes Overview

The GL34G/1 is a single standard recovery rectifier from Vishay Semiconductors, housed in the DO-213AA (GL34) MELF package. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 500 mA. The device exhibits a typical forward voltage drop of 1.2 V at full load and a low reverse leakage current of 5 µA at rated voltage. Its reverse recovery time is specified at 1.5 µs, with a maximum non-repetitive peak forward surge current capability of 10 A. The component operates within a junction temperature range of -65 °C to +175 °C.

Single Diodes Procurement Notes

Verify part authenticity through authorized channels as the GL34G/1 is listed as obsolete by the manufacturer. Confirm that the specific suffix /1 corresponds to the bulk packaging variant rather than tape-and-reel configurations found in other GL34G derivatives. Ensure compliance with RoHS directives if required for the target assembly, noting that newer equivalents like the GL34GHE3 series offer updated environmental certifications.

Single Diodes Selection Notes

Select this component for applications requiring robust standard recovery performance in a compact surface-mount form factor. The 400 V rating provides sufficient margin for common AC line voltages. Consider the 1.5 µs recovery time when evaluating switching frequency limitations compared to fast recovery alternatives. The wide operating temperature range supports deployment in automotive or industrial environments where thermal stability is critical.

Single Diodes Part Context

The GL34G/1 belongs to the SUPERECTIFIER family of surface mount glass passivated junction rectifiers. This series utilizes a specialized Superectifier structure to enhance reliability. The GL34 designation indicates a 400 V, 0.5 A rating within the broader GL34A through GL34J lineup, which varies primarily by reverse voltage specifications while maintaining consistent current handling and package dimensions.

Single Diodes Replacement Considerations

Public confirmed substitute part numbers include GL34GHE3/98 and GL34G/32. These variants share identical electrical ratings and the DO-213AA package but may differ in packaging format or environmental compliance status. Verify pinout compatibility and thermal characteristics before substitution.
