GBLA10-E3/45

Overview

The GBLA10-E3/45 is a glass passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an in-line circuit configuration within a GBL case type, rated for a maximum repetitive peak reverse voltage of 1000 V and a maximum average forward rectified output current of 4.0 A at a case temperature of 50 °C. The device exhibits a typical instantaneous forward voltage drop of 1.0 V per diode at 4.0 A and a maximum DC reverse current of 5.0 μA at 25 °C. It supports a peak forward surge current of 120 A and operates within a junction and storage temperature range of -55 to +150 °C.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via the E3 suffix designation and check for updated End-of-Life notices. Validate datasheet revision dates against current procurement requirements to ensure technical specifications remain accurate.

Selection Notes

Select based on required reverse voltage ratings and thermal management needs. Ensure adequate heat sinking or PCB copper pad dimensions to maintain junction temperatures within the specified operating range. Consider derating curves for ambient temperature variations and verify lead length compatibility with target printed circuit board layouts.
