Product details
Overview
GBPC4004M from Taiwan Semiconductor is a 40A, 400V standard bridge rectifier in GBPC40-M package with integral heatsink, glass-passivated junctions, and 400A peak surge capability-used in AC-DC conversion stages of industrial SMPS.
For engineers reviewing the GBPC4004M datasheet, GBPC4004M pinout, GBPC4004M application, or GBPC4004M equivalent, key selection criteria include repetitive peak reverse voltage (400 V), average forward current (40 A), thermal resistance (1.5 °C/W), mounting flexibility (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 case with cathode parallel to anode orientation per GBPC40-M mechanical specification. It delivers 40 A average forward current at case temperature ≤75°C and supports 8.3 ms half-sine surge up to 400 A without fusing.
Thermal performance is defined by 1.5 °C/W junction-to-case resistance and UL 94V-0 compliant molding compound. Terminal leads are matte tin-plated, J-STD-002 solderable, and pass JESD 201 Class 1A whisker testing.
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 GBPC4004 | Same GBPC40 package, identical 40A/400V ratings, but lacks UL recognition and JESD 201 whisker test compliance | No UL file number; requires additional system-level safety validation | Prefer GBPC4004M where UL E-326243 is mandatory for end-product certification |
| ON Semiconductor GBU4J | Lower current (4A), smaller GBU package, no integral heatsink, RθJC = 10 °C/W | Not suitable for >10 A average loads; requires external heatsink and layout redesign | Select only for space-constrained, low-power auxiliary rails-not as drop-in replacement |
Compared with GBPC4004 and GBU4J, the GBPC4004M uniquely combines 40 A current, 400 V blocking, UL recognition, integral heatsink, and whisker-resistant terminations-making it optimal for certified, high-reliability industrial AC-DC front ends requiring minimal thermal derating.

FAQ
What is the maximum average forward current rating for GBPC4004M?
The GBPC4004M is rated for 40 A average forward current (IF(AV)) when mounted on a heatsink with case temperature maintained at ≤75°C. Derating is required above this temperature per the forward current derating curve in the datasheet; at 100°C case temperature, the usable current drops to approximately 25 A.
Does GBPC4004M have UL recognition, and what is the file number?
Yes, GBPC4004M is UL Recognized under File # E-326243. This certification covers the device's construction, flammability (UL 94V-0), and electrical safety for use in end equipment complying with UL 60950-1 or UL 62368-1 standards.
What is the junction-to-case thermal resistance (RθJC) of GBPC4004M?
The GBPC4004M has a typical junction-to-case thermal resistance of 1.5 °C/W. This value is measured under standardized conditions and enables accurate heatsink sizing-e.g., a 10 °C/W heatsink supports ~57 W of power dissipation at ΔT = 85°C (150°C TJ max − 65°C TC).
How is polarity marked on the GBPC4004M package?
Polarity on GBPC4004M is indicated by a channeled corner and cathode marking on the molded case. The "−" terminal is the cathode output, and the "+" terminal is the anode output; AC1 and AC2 are the two symmetrical AC input terminals. Markings conform to Taiwan Semiconductor's GBPC40-M outline drawing HQ2SD07-GBPC40M-053 REV A.
Is GBPC4004M RoHS compliant and lead-free?
Yes, GBPC4004M is RoHS compliant and lead-free. Its molding compound, internal interconnects, and matte tin-plated terminals meet EU Directive 2011/65/EU requirements. Lead content is below 0.1 wt% across all homogeneous materials, verified per IEC 62321 testing protocols.
