Taiwan Semiconductor Corporation GBPC5004

Overview

GBPC5004 from Taiwan Semiconductor is a 50A, 400V rated standard bridge rectifier with glass-passivated junctions, integrally molded heatsink, and quad-diode configuration in GBPC40 package. It delivers 400A peak surge current, 1.5°C/W junction-to-case thermal resistance, and supports SMPS and AC-DC converter applications requiring high-reliability rectification.

For engineers reviewing the GBPC5004 datasheet, GBPC5004 pinout, GBPC5004 application, or GBPC5004 equivalent, key selection criteria include its 400V repetitive peak reverse voltage (VRRM), 50A average forward current (IF), 400A non-repetitive surge rating (IFSM), RoHS compliance, and UL recognition (E-326243).

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with common cathode and anode terminals. Its glass-passivated junction ensures stable reverse leakage (<10 µA at 25°C) and robust thermal performance up to 150°C junction temperature.

The GBPC5004 uses a GBPC40 molded case with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker testing. Its 1.5°C/W R_θJC enables efficient heat transfer to external heatsinks under continuous 50A conduction.

FAQ

What is the maximum junction temperature rating for GBPC5004?

The GBPC5004 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 environments such as enclosed industrial enclosures or high-power SMPS units. Derating curves confirm usable current capacity down to 0A at 150°C case temperature. GBPC5004 must be mounted to an adequate heatsink to maintain this limit under full 50A load.

Does GBPC5004 have UL recognition and what is the file number?

Yes, GBPC5004 is UL Recognized under file number E-326243, as documented in Taiwan Semiconductor's official datasheet revision G2211. This recognition covers the GBPC40/50 series and validates compliance with UL 60747-1 for discrete semiconductors. The molded compound meets UL 94V-0 flammability rating, supporting use in end equipment requiring safety agency approval. GBPC5004 carries this recognition without requiring additional system-level retesting.

What is the forward voltage drop specification for GBPC5004 at rated current?

The forward voltage drop (V_F) for GBPC5004 is specified as ≤1.1 V per diode at 25A and 25°C junction temperature, per the Electrical Specifications table. This value reflects worst-case conduction loss under typical operating conditions and directly impacts power dissipation (P_cond ≈ 2 × V_F × I_F). At 50A average load, total conduction loss is approximately 55 W, necessitating proper thermal management. GBPC5004's glass-passivated junction helps stabilize V_F over temperature and lifetime.

Is GBPC5004 RoHS compliant and lead-free?

Yes, GBPC5004 is RoHS compliant and lead-free, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. The matte tin-plated leads meet J-STD-002 solderability requirements and pass JESD 201 Class 1A whisker testing. No lead or other RoHS-restricted substances exceed threshold limits. GBPC5004 is suitable for consumer, industrial, and medical-adjacent applications where RoHS compliance is mandatory, though it is not rated for life-sustaining medical use per TSC notice.

What mounting methods are supported by the GBPC5004 package?

GBPC5004 supports four mounting methods per its mechanical data: snap-on (to standard heatsink rails), wrap-around (using terminal bends), solder (direct lead soldering), and PCB mounting (via through-hole pads matching the GBPC40 outline). The package features chamfered corners and cathode indicator markings for polarity verification. Mounting torque must not exceed 20 in-lbs to avoid case cracking. GBPC5004's universal terminals eliminate need for adapter hardware across prototyping and volume production.
