Taiwan Semiconductor Corporation GBPC4001 T0G

Overview

GBPC4001 T0G 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 maximum junction temperature, used in AC-DC conversion stages of industrial power supplies.

For engineers reviewing the GBPC4001 T0G datasheet, GBPC4001 T0G pinout, GBPC4001 T0G application, or GBPC4001 T0G equivalent, key selection criteria include peak reverse voltage (50 V), forward current rating (40 A), thermal resistance (1.5 °C/W), and UL recognition (E-326243) for safety-critical power conversion designs.

Technical Context

This quad-diode bridge integrates four silicon junctions in a single molded case with cathode-anode terminals arranged for universal mounting (snap-on, wrap-around, solder, or PCB). Its glass-passivated die ensures stable reverse leakage (<10 µA at 25°C) and high reliability under thermal cycling.

The GBPC4001 T0G operates within -55°C to +150°C junction range, delivers 1.1 V max forward voltage per diode at 20 A, and achieves 1.5 °C/W junction-to-case thermal resistance-enabling direct heatsink attachment without thermal interface material in many medium-power applications.

FAQ

What is the maximum junction temperature rating for GBPC4001 T0G?

The GBPC4001 T0G has a maximum junction temperature (TJ) rating of +150°C, as specified in its Absolute Maximum Ratings table. This allows sustained operation in thermally demanding environments such as enclosed industrial power supplies. Derating curves in the datasheet confirm usable current capacity down to 0 A at 150°C case temperature. The GBPC4001 T0G must be mounted to an appropriate heatsink to maintain junction temperature within this limit under full-load conditions.

Does GBPC4001 T0G meet RoHS and lead-free requirements?

Yes, GBPC4001 T0G is RoHS compliant and features matte tin-plated leads that are solderable per J-STD-002. The molding compound meets UL 94V-0 flammability rating, and the device passes JESD 201 Class 1A whisker testing-ensuring long-term reliability of solder joints. These qualifications are explicitly stated in the official Taiwan Semiconductor datasheet version G2211 for the GBPC4001 T0G.

What is the forward voltage drop of GBPC4001 T0G at rated current?

The GBPC4001 T0G exhibits a maximum forward voltage (VF) of 1.1 V per diode at IF = 20 A and TJ = 25°C, as confirmed in the Electrical Specifications table. Since it is a full-wave bridge, total conduction drop across the conducting path is approximately 2.2 V under those conditions. This value increases with junction temperature and current-designers should reference the Typical Forward Characteristics curve (Figure 4) for precise loss estimation across operating ranges. The GBPC4001 T0G maintains this performance due to its glass-passivated junction construction.

Is GBPC4001 T0G UL recognized, and what is its file number?

Yes, GBPC4001 T0G is UL Recognized under file number E-326243. This recognition applies to the GBPC40 package family and validates compliance with UL 60747-1 for discrete semiconductors. It supports end-equipment safety certification for industrial and commercial power systems. The UL mark appears on the device body per marking diagram in datasheet page 4, and the recognition covers both GBPC40 and GBPC40-M variants. GBPC4001 T0G's UL status is documented in the Features section of the Taiwan Semiconductor datasheet G2211.

What mounting methods are supported by GBPC4001 T0G?

The GBPC4001 T0G supports four mechanical mounting options: snap-on (to standard heatsink rails), wrap-around (terminal bending for clamping), solder (direct terminal soldering), and PCB mounting (through-hole with 5.59 mm diameter mounting holes). Its universal 4-way terminal design eliminates need for custom tooling. Mounting torque must not exceed 20 in-lbs to avoid case cracking. Polarity is marked on the case with cathode indicator and chamfered corner, ensuring correct orientation during all mounting methods. GBPC4001 T0G's mechanical data is fully detailed in pages 4–5 of the G2211 datasheet.
