Overview
The GBU4M-T is a single-phase bridge rectifier manufactured by Diotec Semiconductor, housed in the GBU surface-mount package. It features a maximum repetitive peak reverse voltage of 1000 V and an average forward rectified current rating of 4 A at 25°C. The device supports a maximum non-repetitive peak forward surge current of 130 A. It operates with a maximum DC blocking voltage of 1000 V and has a maximum RMS input voltage rating of 700 V. The component maintains a low forward voltage drop of 1.1 V at 4 A and exhibits a maximum reverse leakage current of 5 µA at its rated voltage. It is designed for operation across a junction temperature range from -55°C to +150°C.
Feature Summary
- High-voltage capability with 1000 V reverse voltage rating
- Robust surge handling with 130 A peak forward surge current
- Surface-mount construction for automated assembly efficiency
- Extended thermal performance up to 150°C junction temperature
Applications
- General-purpose AC-DC power supply circuits

Procurement Notes
Verify the specific ordering suffix against official Diotec Semiconductor documentation to confirm exact packaging configuration and compliance status. Confirm RoHS and REACH directives alignment with project requirements before finalizing procurement orders.
Selection Notes
Select this component when a 1000 V rating is required for single-phase rectification in space-constrained designs. Ensure the PCB layout accommodates the GBU package dimensions and thermal dissipation needs for continuous 4 A operation.
Part Context
This part belongs to Diotec's GBU series of bridge rectifiers, which are designed for general-purpose applications. The series offers various voltage ratings and current capacities within the same standardized surface-mount footprint to simplify design standardization.
Replacement Considerations
Consult official substitution lists for equivalent parts with matching electrical parameters and pin configurations. Verify that any alternative component meets the same thermal and mechanical specifications.
