Taiwan Semiconductor Corporation GBPC5006

Overview

GBPC5006 from Taiwan Semiconductor is a 50A, 600V standard bridge rectifier with glass-passivated junctions, integrally molded heatsink (R_θJC = 1.5°C/W), and universal 4-way mounting-designed for high-reliability AC-to-DC conversion in industrial power supplies.

For engineers reviewing the GBPC5006 datasheet, GBPC5006 pinout, GBPC5006 application, or GBPC5006 equivalent, key selection factors include its 400A non-repetitive surge rating, 150°C max junction temperature, UL Recognized status (E-326243), RoHS compliance, and compatibility with snap-on/wrap-around/solder/PCB mounting.

Technical Context

This quad-configuration bridge rectifier integrates four silicon diodes in a single GBPC40 package with cathode-anode polarity marked on the case. Its glass-passivated junction ensures stable reverse leakage (<10 µA at rated V_R) and robust thermal performance under continuous 50A forward conduction.

The device supports high-surge operation (I_FSM = 400A, 8.3ms half-sine) and delivers low forward voltage drop (≤1.1 V at 25A, 25°C), enabling efficient power conversion in switching-mode power supplies operating up to 600V peak reverse voltage.

FAQ

What is the maximum junction temperature rating for GBPC5006?

The GBPC5006 has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows sustained operation in high-ambient industrial enclosures. Derating curves confirm usable current capacity down to 0 A at 150°C case temperature. GBPC5006 must be mounted to an appropriate heatsink to maintain this limit under full-load conditions.

Does GBPC5006 have UL recognition?

Yes, GBPC5006 is UL Recognized under file number E-326243, confirming compliance with UL 60950-1 and UL 62368-1 for end-equipment safety. This applies to the GBPC40 package configuration with matte tin-plated leads and UL 94V-0 molding compound. GBPC5006 meets flammability, electrical clearance, and thermal stress requirements for Class 2 power supplies.

What is the forward voltage drop specification for GBPC5006?

Per Taiwan Semiconductor's electrical specifications, GBPC5006 exhibits a maximum forward voltage (V_F) of 1.1 V at I_F = 25 A and T_J = 25°C, measured per diode under pulse test conditions (PW = 0.3 ms). This value reflects typical conduction loss across the bridge under nominal load, directly impacting efficiency in high-current AC/DC converters.

Is GBPC5006 compatible with lead-free reflow soldering?

Yes, GBPC5006 features matte tin-plated leads qualified per J-STD-002 for solderability, including compatibility with lead-free reflow profiles (peak temperature ≤ 260°C). The GBPC40 package's molding compound meets UL 94V-0, and thermal performance data confirms reliability under JEDEC J-STD-020 moisture sensitivity level (MSL) 1 conditions.

What mounting methods does GBPC5006 support?

GBPC5006 supports four mechanical mounting options: snap-on (to chassis rails), wrap-around (terminal bending), solder (through-hole or surface pad), and PCB board mounting-enabled by its universal GBPC40 footprint and 20 in-lb maximum torque rating. The heatsink base is electrically isolated, allowing direct thermal attachment without additional insulators in most configurations.
