Product details
Overview
GBPC5008M from Taiwan Semiconductor is a 50A, 800V standard bridge rectifier in GBPC40-M package with glass-passivated junctions, 400A peak surge current rating, and 1.5°C/W junction-to-case thermal resistance-used in high-efficiency AC-DC converters and SMPS front-end rectification stages.
For engineers reviewing the GBPC5008M datasheet, GBPC5008M pinout, GBPC5008M application, or GBPC5008M equivalent, key selection criteria include rated forward current (50A), repetitive peak reverse voltage (800V), thermal resistance (1.5°C/W), mounting compatibility (snap-on/wrap-around/solder/PCB), and UL recognition (E-326243).
Technical Context
This quad-configuration bridge rectifier integrates four silicon diodes in a single molded package with cathode-parallel-to-anode terminal orientation (GBPC40-M variant). It operates across -55°C to +150°C junction temperature range and supports 8.3ms half-sine surge currents up to 400A.
Thermal performance is enabled by an integrally molded heatsink achieving 1.5°C/W RθJC, while matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 1A whisker requirements. Polarity is marked on the case with channeled corner cathode indicator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 50 A - continuous average current handling capacity at case temperature ≤75°C |
| Repetitive Peak Reverse Voltage (VRRM) | 800 V - maximum non-repetitive reverse voltage the device blocks without breakdown |
| Peak Forward Surge Current (IFSM) | 400 A - withstands single 8.3ms half-sine surge without failure |
| Junction-to-Case Thermal Resistance (RθJC) | 1.5 °C/W - enables efficient heat transfer to external heatsink under full load |
| Forward Voltage per Diode (VF) | 1.1 V max @ 25A, 25°C - determines conduction loss and thermal rise in rectifier stage |
| Reverse Current per Diode (IR) | 10 µA max @ rated VR, 25°C - ensures low leakage in high-impedance hold-up or standby circuits |
| Mounting Torque Limit | 20 in-lbs max - prevents mechanical damage during heatsink fastening |
Pinout & Package

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBPC5008 | Same 50A/800V rating, GBPC40 package, but cathode-perpendicular orientation (non-M variant); no UL recognition cited | Lacks UL E-326243; requires revalidation for safety-critical SMPS designs | Select GBPC5008M when UL compliance and heatsink-mounting flexibility (cathode-parallel) are required |
| ON Semiconductor GBU15K | Lower 15A rating, GBU package (smaller footprint), 800V VRRM, no integrated heatsink, RθJC = 3.0°C/W | Suitable only for <1 kW applications; requires external heatsink and additional mounting hardware | Choose GBPC5008M for ≥1 kW designs where thermal performance and mechanical integration are critical |
Compared with GBPC5008, GBPC5008M offers UL recognition and optimized cathode-parallel mounting, while GBPC5008M outperforms GBU15K in current capacity, thermal resistance, and mechanical integration-making it preferred for industrial-grade 1–3 kW AC-DC systems.

FAQ
What is the maximum junction temperature for GBPC5008M?
The GBPC5008M has a maximum junction temperature (TJ) of +150°C, with operational range from –55°C to +150°C. This rating is maintained under specified thermal conditions-including proper heatsinking and adherence to the 20 in-lbs maximum mounting torque. Exceeding this limit risks irreversible degradation of the glass-passivated junctions in the GBPC5008M.
Does GBPC5008M have UL recognition?
Yes, GBPC5008M is UL Recognized under File # E-326243. This certification applies to the GBPC40-M package configuration and validates its safety for use in end equipment requiring UL compliance, such as commercial SMPS and industrial AC-DC converters. The UL mark is tied to the specific construction and materials used in the GBPC5008M.
What does the "M" suffix indicate in GBPC5008M?
The "M" suffix in GBPC5008M denotes the GBPC40-M package variant, characterized by cathode terminals oriented parallel to the anode terminal-enabling direct heatsink mounting with shared thermal and electrical reference. This differs from the standard GBPC40 (non-M) variant, where cathode terminals are perpendicular. The GBPC5008M marking also includes date code and factory identifier per TSC's YWWF format.
What is the forward voltage drop specification for GBPC5008M?
The GBPC5008M specifies a maximum forward voltage (VF) of 1.1 V per diode at 25 A and 25°C junction temperature, measured under pulsed conditions (PW = 0.3 ms). At elevated temperatures or higher currents, VF increases slightly-actual design values should be verified using the typical forward characteristics curve in the GBPC5008M datasheet.
Can GBPC5008M be mounted directly to a heatsink?
Yes, GBPC5008M is designed for direct heatsink mounting via its integral molded heatsink surface and cathode terminal (–), which serves as both electrical return and thermal interface. Mounting torque must not exceed 20 in-lbs to avoid cracking the epoxy body. Thermal interface material (TIM) is recommended between the GBPC5008M case and heatsink to minimize RθJC and maintain safe junction temperatures.
