Taiwan Semiconductor Corporation GBPC5002

Overview

GBPC5002 from Taiwan Semiconductor is a 50A, 200V standard bridge rectifier in GBPC40 package with glass-passivated junctions, 1.5°C/W junction-to-case thermal resistance, and 400A peak surge current capability-used in AC-DC converters and switching mode power supplies.

For engineers reviewing the GBPC5002 datasheet, GBPC5002 pinout, GBPC5002 application, or GBPC5002 equivalent, key selection criteria include rated forward current (50A), repetitive peak reverse voltage (200V), thermal resistance (1.5°C/W), surge rating (400A), and universal 4-way mounting compatibility.

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with cathode-anode polarity marked on the heatsink base. It operates across -55°C to +150°C junction temperature range and supports snap-on, wrap-around, solder, or PCB mounting via its quad-terminal layout.

Thermal performance is optimized by integrally molded heatsink construction meeting UL 94V-0 flammability rating and JESD 201 Class 1A whisker resistance. Matte tin-plated terminals ensure solderability per J-STD-002 with maximum mounting torque of 20 in-lbs.

FAQ

What is the maximum junction temperature rating for GBPC5002?

The GBPC5002 has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table. This rating applies under steady-state operation with proper heatsinking and accounts for thermal derating curves shown in Figure 1. Operation above this temperature risks permanent degradation of the glass-passivated junctions in GBPC5002.

Does GBPC5002 have a thermally conductive metal base?

Yes, GBPC5002 features an integrally molded heatsink base that serves as the negative DC terminal (–) and provides direct thermal conduction path. The datasheet confirms the heatsink is electrically isolated from internal die but requires mechanical mounting to an external heatsink-no additional insulator is needed unless system grounding dictates isolation.

What does the "02" suffix indicate in GBPC5002?

The "02" in GBPC5002 denotes the 200V repetitive peak reverse voltage (VRRM) rating, per Taiwan Semiconductor's ordering code convention: "005" = 50V, "01" = 100V, "02" = 200V, up to "10" = 1000V. The "50" indicates 50A forward current rating, distinguishing it from the 40A GBPC40xx variants.

Is GBPC5002 RoHS compliant and lead-free?

Yes, GBPC5002 is RoHS compliant and lead-free, as explicitly stated in the FEATURES section and confirmed in the Mechanical Data table. Terminal plating uses matte tin, and the molding compound meets UL 94V-0 flammability rating-both aligned with RoHS Directive 2011/65/EU requirements for GBPC5002.

Can GBPC5002 be mounted directly to a PCB without a heatsink?

GBPC5002 can be mounted to a PCB using its 4-way terminals, but sustained 50A operation requires external heatsinking due to its 1.5°C/W RθJC. At ≤10A average load with adequate copper area (≥10 cm² 2oz Cu), PCB-only cooling may suffice-but thermal simulation or testing is required to validate junction temperature remains ≤150°C for GBPC5002.
