Taiwan Semiconductor Corporation GBPC4010

Overview

GBPC4010 from Taiwan Semiconductor is a 40A, 1000V standard single-phase bridge rectifier in GBPC40 package with glass-passivated junctions, 1.5°C/W junction-to-case thermal resistance, and 400A peak surge current rating. It delivers high-efficiency AC-to-DC conversion in industrial power supplies requiring robust thermal performance and UL recognition.

For engineers reviewing the GBPC4010 datasheet, GBPC4010 pinout, GBPC4010 application, or GBPC4010 equivalent, key selection criteria include repetitive peak reverse voltage (1000 V), average forward current (40 A), forward voltage per diode (≤1.1 V at 20 A), thermal resistance (1.5 °C/W), and UL Recognized File # E-326243 compliance.

Technical Context

This quad-diode bridge rectifier integrates four silicon diodes in a single molded case with integral heatsink for low thermal resistance. Its glass-passivated junction ensures stable reverse leakage (<10 µA at 25°C) and high reliability under repeated surge stress (400 A, 8.3 ms half-sine).

The GBPC4010 supports universal mounting - snap-on, wrap-around, solder, or PCB - with matte tin-plated leads compliant to J-STD-002 and JESD 201 Class 1A whisker testing. Polarity is marked on the case with channeled cathode indicator.

FAQ

What is the maximum junction temperature rating for GBPC4010?

The GBPC4010 has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings table. This allows reliable operation in high-ambient environments when paired with appropriate heatsinking. The device's 1.5°C/W thermal resistance enables effective heat dissipation, and derating curves confirm usable current capacity up to 75°C case temperature at full 40 A rating. GBPC4010 must not be operated beyond this limit to avoid permanent parametric shift or failure.

Does GBPC4010 have UL recognition and what is the file number?

Yes, GBPC4010 is UL Recognized under File # E-326243, as confirmed in the official Taiwan Semiconductor datasheet. This certification covers the GBPC40 package family and validates compliance with UL 60747-4 for semiconductor devices. The recognition applies to both GBPC40 and GBPC40-M variants and supports end-equipment safety approvals in North America without requiring additional component-level testing.

What is the forward voltage specification for GBPC4010 and under what conditions is it measured?

The GBPC4010 forward voltage is specified as ≤1.1 V per diode at I_F = 20 A and T_J = 25°C, measured using a 0.3 ms pulse width test. Since the device contains four series-connected diodes in bridge configuration, the total forward drop across the bridge is ≤2.2 V under those conditions. This value is critical for calculating conduction losses in high-current rectifier designs and is validated across production lots per Taiwan Semiconductor's electrical specifications table.

How does the GBPC4010 differ from the GBPC4010-M variant?

The GBPC4010-M differs from GBPC4010 only in terminal orientation: the cathode terminal is parallel to the anode in the GBPC4010-M variant, whereas GBPC4010 uses the standard GBPC40 footprint with perpendicular cathode/anode alignment. Both share identical electrical ratings, thermal performance (R_θJC = 1.5°C/W), mechanical dimensions, and marking format. Mounting torque remains 20 in-lbs maximum for both versions.

Is GBPC4010 RoHS compliant and what whisker testing standard does it meet?

Yes, GBPC4010 is RoHS compliant and meets JESD 201 Class 1A whisker testing requirements, as documented in the Mechanical Data section of the Taiwan Semiconductor datasheet. The matte tin-plated leads are solderable per J-STD-002, and the molding compound complies with UL 94V-0 flammability rating. These qualifications ensure suitability for lead-free assembly and long-term reliability in vibration-prone or high-humidity industrial environments.
