Product details
Overview
GBPC50005M from Taiwan Semiconductor is a 50A, 50V standard bridge rectifier with glass-passivated junctions, integrally molded heatsink (RθJC = 1.5°C/W), and universal 4-way terminals for snap-on/wrap-around/solder/PCB mounting - used in AC-DC converters and switching mode power supplies.
For engineers reviewing the GBPC50005M datasheet, GBPC50005M pinout, GBPC50005M application, or GBPC50005M equivalent, key selection factors include its 50A average forward current, 400A non-repetitive surge rating, 1.1V max forward voltage at 25A, 10µA max reverse leakage, and UL Recognized (E-326243) RoHS-compliant construction.
Technical Context
This quad-configuration bridge rectifier integrates four silicon diodes in a single GBPC40-M package with cathode-parallel-to-anode terminal orientation. It operates across -55°C to +150°C junction temperature range and supports high thermal dissipation via low-resistance heatsink interface.
Rated for 50V repetitive peak reverse voltage (VRRM) and 35V RMS reverse voltage, it delivers 400A IFSM (8.3ms half-sine) with 664 A²s fusing I²t rating - enabling robust transient handling in industrial and SMPS front-end rectification stages.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBPC5005 | Same 50A/50V rating, GBPC40 package, but lead finish is SnPb (non-RoHS); no UL recognition cited | Limited to legacy industrial designs where RoHS exemption applies and UL listing not required | Select only if SnPb soldering process is mandated and UL E-326243 is not needed |
| ON Semiconductor GBPC5005-M | Identical GBPC40-M package, RoHS, UL recognized (E237725), but VF = 1.2V max (vs. 1.1V) at 25A | Suitable for cost-sensitive SMPS where 0.1V higher conduction loss is acceptable | Prefer when dual UL listings are unnecessary and minor efficiency trade-off is acceptable |
Compared with GBPC50005M, GBPC5005 lacks RoHS compliance and UL recognition, while GBPC5005-M trades 0.1V higher forward drop for alternate UL listing - making GBPC50005M optimal for new RoHS/UL-certified industrial power designs requiring lowest conduction loss.

FAQ
What is the maximum junction temperature rating for GBPC50005M?
The GBPC50005M has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments when paired with appropriate heatsinking. Thermal derating begins above 25°C ambient, and the device must remain within this limit during all operational modes including surge events to ensure reliability and longevity of GBPC50005M.
Does GBPC50005M support PCB mounting?
Yes, GBPC50005M supports PCB mounting via its universal 4-way terminals - including direct soldering to printed circuit boards. The GBPC40-M package features matte tin-plated leads compliant with J-STD-002 solderability standards, and its footprint matches standard through-hole layouts for bridge rectifiers. Mechanical mounting torque must not exceed 20 in-lbs to avoid damage to GBPC50005M's molded case or internal bonds.
What is the forward voltage specification for GBPC50005M at rated current?
The GBPC50005M specifies a maximum forward voltage (VF) of 1.1 V at 25 A and 25°C junction temperature, per electrical specifications table. This value is measured per diode under pulsed conditions (PW = 0.3 ms). At full 50 A average current, VF increases due to self-heating, and system-level thermal design must account for this to maintain safe GBPC50005M operation.
Is GBPC50005M RoHS compliant and UL recognized?
Yes, GBPC50005M is RoHS compliant and UL Recognized under File # E-326243. This dual compliance is explicitly stated in the FEATURES section and confirmed in the Mechanical Data and Ordering Information pages of the official Taiwan Semiconductor datasheet. These certifications validate GBPC50005M for use in environmentally regulated and safety-critical end equipment sold in EU and North American markets.
How does the GBPC40-M package differ from GBPC40 in GBPC50005M?
The GBPC40-M variant used in GBPC50005M features cathode-parallel-to-anode terminal orientation - distinct from standard GBPC40 - enabling optimized PCB layout for polarity-sensitive designs. Dimensional drawings confirm identical outline and heatsink geometry, but marking diagram and terminal polarity alignment differ. This configuration ensures correct DC polarity assignment without board-level wire reversal when using GBPC50005M in new designs.
