Taiwan Semiconductor Corporation GBPC50005

Overview

GBPC50005 from Taiwan Semiconductor is a 50A, 50V standard bridge rectifier with glass-passivated junctions, integrally molded heatsink (R_θJC = 1.5°C/W), and universal 4-way terminals for snap-on, wrap-around, solder, or PCB mounting - used in AC-to-DC conversion stages of industrial power supplies.

For engineers reviewing the GBPC50005 datasheet, GBPC50005 pinout, GBPC50005 application, or GBPC50005 equivalent, key selection criteria include its 400A non-repetitive surge rating, 150°C max junction temperature, UL Recognized status (E-326243), RoHS compliance, and compatibility with high-reliability SMPS designs requiring stable thermal performance under continuous conduction mode.

Technical Context

This quad-configuration bridge rectifier integrates four silicon diodes in a single GBPC40 package with cathode-anode polarity marked on the heatsink base. Its glass-passivated junction ensures stable reverse leakage (<10 µA at 25°C) and robust surge tolerance (I²t = 664 A²s).

The device operates across –55°C to +150°C junction range and delivers 1.1 V max forward voltage per diode at rated current (GBPC50: 25 A, 25°C), with thermal resistance optimized via direct-mount heatsink interface and matte tin-plated leads compliant with J-STD-002 solderability.

FAQ

What is the maximum junction temperature rating for GBPC50005?

The GBPC50005 has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings table. This allows sustained operation in high-ambient environments such as enclosed industrial enclosures or thermally constrained LED luminaires. The device must be mounted to a heatsink capable of maintaining case temperature below this limit under worst-case load conditions. GBPC50005's R_θJC of 1.5°C/W defines the thermal path from junction to heatsink interface.

Does GBPC50005 have UL recognition and what is the file number?

Yes, GBPC50005 is UL Recognized under file #E-326243, as confirmed in the official Taiwan Semiconductor datasheet. This certification applies to the GBPC40/50 series and validates compliance with UL 60747-4 for semiconductor devices. The recognition covers both GBPC50005 and other variants in the family, supporting end-product safety approvals in North America without additional component-level testing.

What is the forward voltage drop specification for GBPC50005 at rated current?

Per the electrical specifications table, GBPC50005 exhibits a maximum forward voltage (V_F) of 1.1 V per diode at 25°C junction temperature and 25 A forward current - consistent with its 50 A rating. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At elevated temperatures or higher currents, V_F increases predictably per the typical forward characteristics curve in the GBPC50005 datasheet.

Is GBPC50005 RoHS compliant and what lead finish does it use?

Yes, GBPC50005 is RoHS compliant, using matte tin-plated leads that meet J-STD-002 solderability requirements. The terminal plating is verified per JEDEC standards and passes JESD 201 Class 1A whisker testing. No lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE substances exceed EU RoHS thresholds. This ensures compatibility with lead-free reflow processes and environmental compliance for global deployment.

How is polarity marked on the GBPC50005 package?

Polarity on GBPC50005 is marked directly on the molded case: a "+" symbol indicates the DC positive output terminal, while a cathode symbol (─|─) marks the DC negative output terminal, which is electrically connected to the integral heatsink base. AC input terminals (AC1 and AC2) are unmarked but located symmetrically opposite the DC terminals. The cathode indicator appears on the chamfered corner adjacent to the "–" marking, per the official GBPC40 outline drawing.
