Taiwan Semiconductor Corporation GBPC4001

Overview

GBPC4001 from Taiwan Semiconductor is a 40A, 50V glass-passivated single-phase bridge rectifier in GBPC40 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 switching mode power supplies.

For engineers reviewing the GBPC4001 datasheet, GBPC4001 pinout, GBPC4001 application, or GBPC4001 equivalent, key selection factors include repetitive peak reverse voltage (50 V), forward current rating (40 A), thermal resistance (1.5 °C/W), mounting flexibility (snap-on/wrap-around/solder/PCB), and UL recognition (E-326243).

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single quad configuration with common cathode and anode terminals, enabling full-wave AC-to-DC conversion without external interconnection. Its glass-passivated junction ensures stable reverse leakage (<10 µA at 25°C) and high reliability under thermal cycling.

The GBPC4001 uses a molded GBPC40 case with matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 1A whisker testing. Thermal performance is optimized via integrally molded heatsink geometry, achieving 1.5°C/W R_θJC for direct heat transfer to external heatsinks.

Key Specifications

Pinout & Package

GBPC4001 is housed in the GBPC40 molded plastic package (29.0 × 21.3 × 17.6 mm), featuring four-way universal terminals: two AC input pins (marked ~), one anode (+), and one cathode (−). The heatsink base is electrically isolated and thermally conductive.

FAQ

What is the maximum junction temperature rating for GBPC4001?

The GBPC4001 has a maximum junction temperature (T_J) of +150°C and a minimum of −55°C. This wide operating range allows reliable use in industrial enclosures with ambient temperatures up to +85°C when properly heatsinked. Thermal design must account for its 1.5°C/W junction-to-case resistance to avoid exceeding 150°C under full 40 A load.

Does GBPC4001 support PCB mounting?

Yes, GBPC4001 supports PCB mounting via its four-way terminal configuration - including dedicated solder pads for AC1, AC2, +, and −. The GBPC40 package outline includes defined pad dimensions and lead spacing compatible with standard through-hole PCB layouts, and its matte tin-plated leads meet J-STD-002 solderability requirements.

What is the forward voltage drop specification for GBPC4001?

The GBPC4001 has a maximum forward voltage of 1.1 V per diode at 20 A and 25°C junction temperature. Since it contains four series-connected diodes in the conduction path (two per half-cycle), the total forward drop across the bridge is ≤2.2 V under those conditions - critical for calculating conduction losses in high-efficiency SMPS designs.

Is GBPC4001 UL recognized?

Yes, GBPC4001 is UL Recognized under File # E-326243. This certification confirms compliance with UL 60950-1 and UL 62368-1 for use in information technology and audio/video equipment, supporting end-product safety approvals without additional component-level testing.

What does the "005" suffix in GBPC4001 indicate?

The "005" in GBPC4001 denotes the 50 V repetitive peak reverse voltage (V_RRM) rating - per Taiwan Semiconductor's ordering convention where "005" = 50 V, "01" = 100 V, up to "10" = 1000 V. Thus, GBPC4001 is the 40 A, 50 V variant in the GBPC40 family, distinct from higher-voltage versions like GBPC4004 (400 V).
