Product details
Overview
GBPC40005 from Taiwan Semiconductor is a 40A, 50V glass-passivated single-phase bridge rectifier in GBPC40 package with integral heatsink, rated for 400A non-repetitive surge current and 150°C max junction temperature, used in AC-DC conversion stages of industrial power supplies.
For engineers reviewing the GBPC40005 datasheet, GBPC40005 pinout, GBPC40005 application, or GBPC40005 equivalent, key selection criteria include repetitive peak reverse voltage (50 V), forward current rating (40 A), 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 cathode and anode terminals arranged for universal mounting. Its glass-passivated die ensures stable reverse leakage (<10 µA at 25°C) and high reliability under thermal cycling.
The GBPC40005 operates within -55°C to +150°C junction range and delivers 1.1 V typical forward voltage per diode at 20 A, with 664 A²s fusing I²t rating - enabling robust handling of inrush and transient surges in switching-mode power supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBPC4005 | Same 40 A / 50 V rating, identical GBPC40 package, but rated for 350 A IFSM (vs. 400 A) | Suitable where lower surge margin is acceptable; same mounting and footprint | Select GBPC40005 when higher surge immunity is required for high-inrush loads |
| ON Semiconductor GBU4K | 40 A / 50 V, but GBU package (smaller, 2-pin AC input), higher VF (1.2 V typ), RθJC = 2.0 °C/W | Better suited for space-constrained designs where thermal performance is less critical | Choose GBPC40005 for superior thermal management and universal mounting flexibility |
Compared with Vishay GBPC4005 and ON Semi GBU4K, the GBPC40005 offers the highest surge current rating (400 A) and lowest thermal resistance (1.5 °C/W), making it optimal for thermally demanding, high-reliability AC-DC front-ends requiring field-proven ruggedness.

FAQ
What is the maximum junction temperature rating for GBPC40005?
The GBPC40005 has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows reliable operation in high-ambient environments such as enclosed industrial enclosures or motor drive cabinets. Derating curves confirm usable current capacity down to 0 A at 150°C case temperature. GBPC40005 must be mounted to a heatsink or metal chassis to maintain this limit under full load.
Does GBPC40005 have UL recognition and what is the file number?
Yes, GBPC40005 is UL Recognized under file number E-326243, as confirmed in the official Taiwan Semiconductor datasheet. This certification covers the GBPC40 package construction, flammability (UL 94V-0), and electrical safety performance. GBPC40005 meets UL 60747-4 requirements for discrete semiconductors and supports end-product safety approvals in North America and other UL-accepting regions.
What is the forward voltage specification for GBPC40005 at rated current?
At IF = 20 A and TJ = 25°C, GBPC40005 exhibits a maximum forward voltage (VF) of 1.1 V per diode, measured under pulsed conditions (PW = 0.3 ms). This value reflects conduction loss in one leg of the bridge; total bridge drop is effectively 2 × VF during conduction. GBPC40005 maintains this performance across its operating temperature range, with typical VF rising to ~1.25 V at 125°C junction.
How is polarity marked on the GBPC40005 package?
GBPC40005 uses a channeled corner and "+" symbol adjacent to the positive terminal to indicate polarity. The cathode side (negative output) is marked with a distinct cathode indicator bar near the "–" terminal. Pin 1 (AC1) and Pin 2 (AC2) are unmarked and symmetrical; polarity is defined only between "+" and "–". GBPC40005's marking diagram is documented in datasheet page 4, confirming orientation relative to heatsink plane and chamfered corner.
What mounting methods are supported by GBPC40005?
GBPC40005 supports four mechanical mounting options: snap-on to standard heatsinks, wrap-around clamping, soldering to PCB pads, and direct screw-down using the integral heatsink flange. Mounting torque must not exceed 20 in-lbs to avoid case cracking. All terminals are matte tin-plated and solderable per J-STD-002. GBPC40005's universal terminal design eliminates need for adapter hardware across assembly processes.
