Taiwan Semiconductor Corporation GBPC4002M

Overview

GBPC4002M from Taiwan Semiconductor is a 40A, 200V glass-passivated single-phase bridge rectifier in GBPC40-M package with integral heatsink, 1.5°C/W junction-to-case thermal resistance, and 400A peak surge current rating; used in AC-DC conversion stages of industrial power supplies.

For engineers reviewing the GBPC4002M datasheet, GBPC4002M pinout, GBPC4002M application, or GBPC4002M equivalent, key selection criteria include rated forward current (40A), repetitive peak reverse voltage (200V), thermal resistance (1.5°C/W), surge capability (400A), and terminal mounting flexibility (snap-on/wrap-around/solder/PCB).

Technical Context

This quad-diode bridge integrates four silicon junctions in a single molded package with cathode terminals parallel to anode-confirmed by GBPC40-M marking diagram and mechanical drawings. Its glass-passivated die ensures stable reverse leakage (<10 µA at 25°C) and high reliability under thermal cycling.

The device operates across -55°C to +150°C junction temperature range and delivers 1.1V max forward voltage per diode at 20A/25°C. Its UL 94V-0 molding compound and JESD201 Class 1A whisker compliance support safety-critical and long-life industrial deployments.

Key Specifications

Pinout & Package

GBPC4002M uses the GBPC40-M molded case with four-way terminals: two AC input pins (marked ~), one common anode (+), and one common cathode (–), with cathode lead oriented parallel to anode lead per mechanical drawing HQ2SD07-GBPC40M-053 REV A.

FAQ

What is the maximum junction temperature rating for GBPC4002M?

The GBPC4002M has a maximum junction temperature (TJ MAX) of +150°C, with a storage temperature range of -55°C to +150°C. This rating allows operation in high-ambient industrial environments when mounted to an appropriate heatsink, given its 1.5°C/W junction-to-case thermal resistance. Derating curves in the datasheet confirm usable current down to 0A at 150°C case temperature.

Does GBPC4002M have UL recognition and RoHS compliance?

Yes, GBPC4002M is UL Recognized under File # E-326243 and fully RoHS compliant. Its molding compound meets UL 94V-0 flammability rating, and its matte tin-plated leads satisfy J-STD-002 solderability requirements. These certifications are confirmed in the official Taiwan Semiconductor GBPC40/50 Series datasheet Version G2211.

What does the "M" suffix in GBPC4002M indicate?

The "M" suffix in GBPC4002M denotes the GBPC40-M package variant, where the cathode terminal is oriented parallel to the anode terminal-distinct from the standard GBPC40 package where they are perpendicular. This geometry is optimized for direct heatsink mounting with uniform pressure distribution and is documented in mechanical drawing HQ2SD07-GBPC40M-053 REV A.

What is the forward voltage drop of GBPC4002M at rated current?

At 20A and 25°C junction temperature, GBPC4002M exhibits a maximum forward voltage (VF) of 1.1 V per diode. Since it is a full-wave bridge, total conduction drop is effectively two diode drops in series (2.2 V), resulting in ≤88 W total power dissipation at 40A average output current.

Can GBPC4002M be used in 230VAC input applications?

GBPC4002M is rated for 200V repetitive peak reverse voltage (VRRM), which provides insufficient margin for direct use with 230VAC mains (peak ≈ 325V). It is suitable for 115VAC systems (peak ≈ 162V) with 23% margin. For 230VAC, select GBPC4004M (400V) or GBPC4006M (600V) variants from the same series.
