Taiwan Semiconductor Corporation GBPC15005

Overview

GBPC15005 from Taiwan Semiconductor is a 15A, 50V standard single-phase bridge rectifier with glass-passivated junctions, integrally molded heatsink, and UL Recognized (E-326243) construction; it delivers 300A non-repetitive surge current and operates up to +150°C junction temperature in SMPS and AC–DC converter applications.

For engineers reviewing the GBPC15005 datasheet, GBPC15005 pinout, GBPC15005 application, or GBPC15005 equivalent, key selection criteria include its 1.1V max forward voltage at 7.5A, <5µA reverse leakage at rated VR, 1.5°C/W junction-to-case thermal resistance, and GBPC package with cathode-indicated terminal layout.

Technical Context

The GBPC15005 integrates four silicon diodes in a single-phase full-wave bridge configuration with quad-terminal arrangement (AC1, AC2, +, –), enabling direct AC input rectification without external interconnects. Its glass-passivated junction ensures stable reverse characteristics and low IR drift over temperature.

Thermally optimized via an integrally molded heatsink, the device achieves 1.5°C/W R_θJC, supporting high-power density designs where conduction loss and thermal management are critical-especially in compact 50–100W SMPS front-end stages operating near ambient limits.

Key Specifications

Pinout & Package

GBPC15005 is available at Aetrix Electronics and suitable for industrial AC–DC power supplies, compact switch-mode power supplies, and LED driver input stages requiring stable component supply, long-term lifecycle support, and traceable sourcing.

Supply support for GBPC15005 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving global industrial, computing, and consumer markets since 1979.

The GBPC series was designed specifically for high-reliability, high-current AC–DC front-end rectification in industrial and medical-adjacent power systems-emphasizing thermal robustness, safety certification, and long-term parametric stability.

FAQ

What is the maximum junction temperature rating for GBPC15005?

The GBPC15005 has a maximum junction temperature (T_J) of +150°C, validated across its full operating range. This rating enables use in high-ambient environments when paired with appropriate heatsinking. Derating curves in the datasheet specify allowable average forward current versus case temperature, and GBPC15005 must be operated within those limits to maintain reliability and avoid thermal runaway.

Does GBPC15005 require an external heatsink?

GBPC15005 features an integrally molded heatsink and is rated for 15A average forward current with proper PCB copper area and/or optional external heatsink attachment. At full load and 75°C case temperature, no external heatsink is strictly required-but for sustained 15A operation above 50°C ambient, bolting the GBPC15005 baseplate to a chassis or heatsink is recommended to maintain T_J ≤150°C.

What does the "005" suffix indicate in GBPC15005?

The "005" in GBPC15005 denotes the 50V repetitive peak reverse voltage (V_RRM) rating. Per Taiwan Semiconductor's ordering convention, "005" = 50V, "01" = 100V, "02" = 200V, etc. Thus, GBPC15005 is the 15A, 50V variant of the GBPC15xx family, distinct from higher-voltage versions like GBPC15010 (1000V).

Is GBPC15005 RoHS compliant and lead-free?

Yes, GBPC15005 is RoHS compliant and manufactured with lead-free terminations. The matte tin-plated leads meet J-STD-002 solderability requirements, and the molding compound complies with UL 94V-0 flammability standards. Taiwan Semiconductor confirms full compliance with Directive 2011/65/EU and subsequent amendments, including exemption 7a for lead in high-melting-temperature solder alloys used internally.

How is polarity marked on the GBPC15005 package?

GBPC15005 uses a cathode indicator: a chamfered corner adjacent to the "+" terminal, with the "–" terminal designated as the cathode output. The marking diagram on the case shows "P/N", "YWWF" (date/factory code), and the cathode symbol (–) near the negative terminal. Polarity must be verified visually before PCB layout or assembly, as incorrect orientation causes immediate short-circuit failure.
