Product details
Overview
GBPC4004 T0G from Taiwan Semiconductor is a 40A, 400V 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 SMPS.
For engineers reviewing the GBPC4004 T0G datasheet, GBPC4004 T0G pinout, GBPC4004 T0G application, or GBPC4004 T0G equivalent, key selection factors include its 40A average forward current, 400V repetitive peak reverse voltage, 1.1V max forward voltage at 20A, 1.5°C/W junction-to-case thermal resistance, and universal 4-way mounting terminals.
Technical Context
This discrete bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with cathode and anode terminals on opposite sides of the molded case. Its glass-passivated junction ensures stable reverse leakage (≤10µA at 25°C) and high reliability under thermal cycling.
The GBPC40 package features a thermally optimized plastic body with integral heatsink, enabling direct mounting to external heat sinks via screw or clip. Polarity is marked with channeled corner and cathode indicator, and terminals meet J-STD-002 solderability and JESD 201 Class 1A whisker requirements.

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 lead finish is SnPb (non-RoHS) | Not suitable for RoHS-compliant end products; requires exemption documentation | Select GBPC4004 T0G when RoHS compliance and JESD 201 whisker resistance are mandatory |
| ON Semiconductor GBU4J | Lower 4A rating, GBU package (smaller, no integral heatsink), 600V VRRM | Requires external heatsink and derating for >10A loads; unsuitable for 40A continuous use | Choose GBPC4004 T0G where 40A average current and integrated thermal management are required |
Compared with GBPC4004 T0G, Vishay GBPC404 offers identical electrical and mechanical specs but lacks RoHS compliance, while ON Semi GBU4J trades current capacity and thermal performance for smaller size-making GBPC4004 T0G the only option meeting 40A, 400V, RoHS, and self-heatsink requirements simultaneously.

FAQ
What is the maximum average forward current rating for GBPC4004 T0G?
The GBPC4004 T0G is rated for 40 A average forward current (IF) at case temperature ≤75°C with adequate heatsinking. This rating assumes natural convection or minimal airflow; derating is required above 75°C case temperature per the forward current derating curve in the datasheet. The GBPC4004 T0G achieves this with its integral heatsink and 1.5°C/W thermal resistance.
Does GBPC4004 T0G support universal mounting methods?
Yes, GBPC4004 T0G features universal 4-way terminals compatible with snap-on, wrap-around, solder, and PCB board mounting. Its GBPC40 package includes robust matte tin-plated leads that meet J-STD-002 solderability standards and JESD 201 Class 1A whisker resistance, ensuring reliable mechanical and electrical attachment across all mounting styles.
What is the repetitive peak reverse voltage (VRRM) of GBPC4004 T0G?
The GBPC4004 T0G has a repetitive peak reverse voltage (VRRM) of 400 V, meaning each diode leg can block up to 400 V in reverse bias without breakdown. This corresponds to a 280 V RMS reverse voltage rating and supports 230 VAC mains input with standard safety margins, as confirmed in the Absolute Maximum Ratings table.
Is GBPC4004 T0G RoHS compliant and certified?
Yes, GBPC4004 T0G is RoHS compliant and carries UL Recognition under file #E-326243. Its molding compound meets UL 94V-0 flammability rating, and terminals pass JESD 201 Class 1A whisker testing. These certifications are documented in the Mechanical Data and Features sections of the official Taiwan Semiconductor datasheet.
What is the thermal resistance from junction to case (RθJC) for GBPC4004 T0G?
The junction-to-case thermal resistance (RθJC) of GBPC4004 T0G is 1.5°C/W, measured under standard test conditions. This low value results from its integrally molded heatsink structure and enables efficient heat transfer to an external heatsink, supporting continuous 40 A operation with appropriate thermal design-verified in the Thermal Performance section of the datasheet.
