Product details
Overview
GBPC4010M from Taiwan Semiconductor is a 40A, 1000V standard single-phase bridge rectifier in GBPC40-M package with integral heatsink, glass-passivated junctions, and 4-way mounting (snap-on/wrap-around/solder/PCB). It delivers 400A non-repetitive surge current and operates up to 150°C junction temperature, used in high-reliability AC–DC conversion stages of industrial SMPS.
For engineers reviewing the GBPC4010M datasheet, GBPC4010M pinout, GBPC4010M application, or GBPC4010M equivalent, key selection criteria include peak reverse voltage (1000V), average forward current (40A), thermal resistance (1.5°C/W), surge rating (400A @ 8.3ms), and UL recognition (E-326243) for safety-critical power supplies.
Technical Context
This quad-diode bridge integrates four silicon junctions in a single molded case with cathode parallel to anode terminal orientation (GBPC40-M variant). Its glass-passivated chips ensure stable reverse leakage (<10 µA at 25°C) and robust surge handling (I²t = 664 A²s).
The GBPC40-M mechanical design features matte tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and 20 in-lb maximum mounting torque - optimized for direct heatsink attachment and high-power conduction in compact AC–DC front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands peak reverse voltage up to 1000V without breakdown, enabling use in 700V RMS line applications. |
| IF(AV) | 40 A - Sustains continuous average forward current of 40A at TC = 100°C, defining steady-state power handling capability. |
| IFSM | 400 A - Handles 8.3ms half-sine surge current up to 400A, critical for inrush protection in switched-mode supplies. |
| RθJC | 1.5 °C/W - Low junction-to-case thermal resistance enables efficient heat transfer to external heatsink under full load. |
| VF per diode | 1.1 V max @ 20A, 25°C - Forward voltage drop limits conduction loss and self-heating during operation. |
| IR | 10 µA max @ rated VR, 25°C - Ultra-low reverse leakage preserves efficiency and reliability in high-impedance bias networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBPC4010 | Same GBPC40 package, identical 40A/1000V ratings, but lacks UL recognition and uses standard GBPC40 (not -M) terminal orientation. | No integral heatsink mounting surface; requires external heatsink with thermal pad or paste. | Preferred where UL certification is not mandated and board-level heatsinking is already designed. |
| ON Semiconductor GBU10K | Lower current rating (10A), smaller GBU package, no integral heatsink, 1000V VRRM retained. | Not suitable for 40A continuous loads; limited to low-power auxiliary supplies or sensing circuits. | Select only for space-constrained auxiliary rails where 40A capacity is unnecessary. |
Compared with GBPC4010M, GBPC4010 offers identical electrical specs but requires added thermal interface for heatsink mounting, while GBU10K sacrifices 75% current capacity for footprint reduction - making GBPC4010M optimal for thermally demanding, safety-certified 40A bridge applications.

FAQ
What is the maximum junction temperature rating for GBPC4010M?
The GBPC4010M has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows sustained operation in high-ambient environments when mounted on an adequately sized heatsink. Thermal derating curves in the datasheet define usable current vs. case temperature, and GBPC4010M must not exceed 150°C at the silicon junction under any operating condition.
Does GBPC4010M have UL recognition, and what is the file number?
Yes, GBPC4010M is UL Recognized under file # E-326243, confirming compliance with UL 60747-4 for discrete semiconductor devices. This recognition applies to the GBPC40-M package variant and supports end-equipment safety certifications including UL 62368-1 and UL 60950-1. The marking "UL" appears on the device body per certification requirements.
What is the forward voltage drop specification for GBPC4010M at rated current?
GBPC4010M specifies a maximum forward voltage (VF) of 1.1 V per diode at IF = 20 A and TJ = 25°C, measured under pulsed conditions (PW = 0.3 ms). At full 40A average current and elevated temperature, VF increases - actual system-level conduction loss must be calculated using the typical VF vs. IF curve and thermal resistance data provided in the datasheet.
How is the polarity marked on GBPC4010M, and what does the cathode indicator signify?
GBPC4010M uses a channeled corner and printed "–" symbol adjacent to the cathode terminal (– pin) as the polarity indicator. The cathode terminal is electrically connected to the integral heatsink base, meaning the heatsink becomes part of the cathode circuit. Mounting must ensure electrical isolation unless the heatsink is intentionally biased to cathode potential.
What mounting torque should be applied when securing GBPC4010M to a heatsink?
The maximum recommended mounting torque for GBPC4010M is 20 in-lbs (2.26 N·m), as specified in the mechanical data section. Exceeding this value risks cracking the molded case or damaging internal wire bonds. Use a calibrated torque screwdriver and flat, clean heatsink surfaces; no additional thermal compound is required due to the integral heatsink's direct metal-to-metal contact design.
