Product details
Overview
GBPC4004 from Taiwan Semiconductor is a 40A, 400V standard single-phase bridge rectifier in GBPC40 package with glass-passivated junctions, 1.5°C/W junction-to-case thermal resistance, and 400A peak surge current rating; used in AC-DC conversion stages of industrial power supplies and motor drive front-ends.
For engineers reviewing the GBPC4004 datasheet, GBPC4004 pinout, GBPC4004 application, or GBPC4004 equivalent, key selection criteria include repetitive peak reverse voltage (400V), average forward current (40A), thermal resistance (1.5°C/W), mounting compatibility (snap-on/wrap-around/solder/PCB), and UL recognition (E-326243).
Technical Context
This quad-diode bridge integrates four silicon junctions in a single molded package with integral heatsink geometry optimized for conduction and thermal dissipation. Its glass-passivated chip junction ensures stable reverse leakage (<10 µA at 25°C) and long-term reliability under repeated surge stress.
The device supports universal 4-way terminal mounting-snap-on, wrap-around, solder, or PCB-and meets JESD201 Class 1A whisker resistance and UL 94V-0 flammability standards. Polarity is marked on case with cathode indicator at channeled corner.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBPC404 | Same 40A/400V rating, identical GBPC40 package, but uses epoxy-molded construction (not glass-passivated junction) | Slightly higher IR (≤50 µA vs. ≤10 µA) and no UL file number; suitable where leakage and certification are non-critical | Select GBPC4004 when low leakage and UL recognition are mandatory for safety-critical AC-DC stages |
| ON Semiconductor GBU4J | Lower current rating (4A), smaller GBU package, no integral heatsink, RθJC = 10°C/W | Not interchangeable-requires redesign for thermal management and PCB layout due to 10× lower IF and different footprint | Use only for low-power auxiliary supplies; GBPC4004 remains necessary for 40A primary rectification |
Compared with GBPC4004, GBPC404 offers mechanical interchangeability but lacks glass passivation and UL recognition, while GBU4J serves entirely different power classes and cannot replace GBPC4004 without system-level redesign.

FAQ
What is the maximum junction temperature for GBPC4004?
The GBPC4004 has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table. This limit applies under continuous forward conduction at rated current and requires proper heatsinking to maintain junction temperature within specification during operation. Exceeding 150°C risks permanent degradation of the glass-passivated junctions in GBPC4004.
Does GBPC4004 support PCB mounting?
Yes, GBPC4004 supports PCB mounting via its universal 4-way terminals, including direct solder attachment to plated-through holes. The GBPC40 package features matte tin-plated leads compliant with J-STD-002, and its 29.0 × 28.5 mm footprint is defined in TSC drawing HQ2SD07-GBPC40-052 REV A. Mechanical mounting torque must not exceed 20 in-lbs.
What is the forward voltage drop of GBPC4004 at rated current?
The GBPC4004 exhibits a maximum forward voltage drop (VF) of 1.1 V per diode at IF = 20 A and TJ = 25°C, as specified in the electrical characteristics table. Since it is a full-wave bridge, total conduction loss across two series diodes equals up to 2.2 V at 20 A, directly impacting efficiency and thermal design in GBPC4004-based power supplies.
Is GBPC4004 RoHS compliant and UL recognized?
Yes, GBPC4004 is RoHS compliant and UL Recognized under File # E-326243, as confirmed in the FEATURES section of the official datasheet. These certifications apply to the GBPC40 package variant and are valid for use in commercial and industrial end equipment requiring regulatory compliance in North America and EU markets.
How does the GBPC4004 differ from GBPC4004M?
The GBPC4004M variant features cathode terminals oriented parallel to anode terminals (per mechanical data), whereas GBPC4004 uses standard orthogonal terminal alignment. Both share identical electrical specs and thermal performance, but GBPC4004M enables alternative board layout routing in space-constrained designs. Mounting torque and marking code format also differ per TSC's ordering documentation.
