Taiwan Semiconductor Corporation GBPC4002

Overview

GBPC4002 from Taiwan Semiconductor is a 40A, 200V rated 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 conversion stages of industrial switching mode power supplies.

For engineers reviewing the GBPC4002 datasheet, GBPC4002 pinout, GBPC4002 application, or GBPC4002 equivalent, key selection criteria include repetitive peak reverse voltage (200V), average forward current (40A), thermal resistance (1.5°C/W), surge rating (400A), and universal 4-way mounting compatibility.

Technical Context

This quad-configuration bridge rectifier integrates four silicon diodes in a single molded case with integral heatsink, enabling high-power AC-to-DC conversion without external thermal management for moderate-duty cycles. Its glass-passivated junction ensures stable reverse leakage (<10 µA at 25°C) and long-term reliability under thermal cycling.

The GBPC4002 supports snap-on, wrap-around, solder, and PCB board mounting via four terminals, with cathode parallel to anode orientation (GBPC40-M variant). It meets UL 94V-0 flammability, JESD201 Class 1A whisker resistance, and RoHS compliance.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving industrial, computing, and consumer markets since 1979.

The GBPC40/50 series was designed specifically for high-current, high-reliability AC-DC front-end rectification in industrial power supplies and motor control systems where thermal robustness and surge resilience are critical.

FAQ

What is the maximum junction temperature rating for GBPC4002?

The GBPC4002 has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the Taiwan Semiconductor datasheet. This rating allows sustained operation in high-ambient environments when mounted to an appropriate heatsink with thermal interface. Derating curves confirm usable current capacity down to 0A at 150°C case temperature. GBPC4002 must not exceed this limit to ensure long-term reliability.

Does GBPC4002 support PCB mounting?

Yes, GBPC4002 supports PCB mounting as one of its four universal terminal options (snap-on, wrap-around, solder, or PCB board mounting). Its GBPC40-M package features tinned leads compliant with J-STD-002 for solderability and is designed for through-hole insertion into standard PCB footprints matching the 29.00 × 28.50 mm outline. Mechanical drawings confirm lead pitch and hole spacing for direct layout integration.

What is the forward voltage drop specification for GBPC4002 at rated current?

The GBPC4002 specifies a maximum forward voltage (VF) of 1.1 V per diode at IF = 20 A and TJ = 25°C, per electrical specifications in the Taiwan Semiconductor datasheet. This value reflects conduction loss under typical operating conditions and is measured using pulse testing (PW = 0.3 ms). At higher temperatures or currents, VF increases predictably per the device's forward characteristic curve.

Is GBPC4002 RoHS compliant and UL recognized?

Yes, GBPC4002 is RoHS compliant and UL Recognized under File # E-326243. The molding compound meets UL 94V-0 flammability requirements, and terminals pass JESD201 Class 1A whisker testing. These certifications are documented in the official Taiwan Semiconductor GBPC40/50 series datasheet (Version G2211) and confirmed on TSC's product compliance portal.

How does the thermal resistance of GBPC4002 compare to standard GBU-series rectifiers?

GBPC4002 has a junction-to-case thermal resistance (RθJC) of 1.5°C/W, significantly lower than typical GBU-series devices (e.g., GBU4K at 2.5°C/W), due to its integrally molded heatsink. This 40% improvement enables more efficient heat transfer to external heatsinks without thermal interface pads in many applications. The lower RθJC directly extends safe operating area under continuous 40A load conditions.
