Taiwan Semiconductor Corporation GBPC1510

Overview

GBPC1510 from Taiwan Semiconductor is a 15A, 1000V standard bridge rectifier with glass-passivated junctions, integrally molded heatsink, and UL Recognized (E-326243) construction. It delivers low thermal resistance (1.5°C/W), typical reverse leakage <0.2μA at 25°C, and 300A peak surge current for AC/DC conversion in industrial power supplies.

For engineers reviewing the GBPC1510 datasheet, GBPC1510 pinout, GBPC1510 application, or GBPC1510 equivalent, key selection criteria include its 1000V V_RRM, 15A average forward current, quad configuration, GBPC package mechanical footprint, and thermal performance under sustained conduction.

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration. Its glass-passivated junction ensures stable reverse characteristics up to 150°C junction temperature, while the integrally molded heatsink enables direct mounting to external heat sinks without additional insulation.

The device operates with a maximum forward voltage of 1.1V per diode at rated current and exhibits typical junction-to-case thermal resistance of 1.5°C/W - critical for thermal management in compact SMPS designs where ambient temperatures exceed 70°C.

FAQ

What is the maximum junction temperature rating for GBPC1510?

The GBPC1510 has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed industrial enclosures or near heat-generating components. Derating curves confirm usable current capacity down to 0A at 150°C case temperature, and thermal design must ensure T_J does not exceed this limit during worst-case load and ambient conditions. GBPC1510's 1.5°C/W R_θJC enables accurate junction temperature prediction using measured case temperature.

Does GBPC1510 require thermal compound when mounted to a heatsink?

GBPC1510 does not require thermal compound when mounted directly to a flat, clean aluminum heatsink using the specified 20 in-lbs maximum torque. Its integrally molded heatsink features a machined copper base with optimized surface finish for metal-to-metal contact. Thermal compound may be used if surface flatness exceeds 0.05mm or if mounting pressure is inconsistent, but doing so adds interfacial resistance and is unnecessary in standard implementations. GBPC1510's R_θJC value of 1.5°C/W assumes direct metal contact without interface material.

What is the reverse recovery time (t_rr) specification for GBPC1510?

The GBPC1510 datasheet does not specify reverse recovery time (t_rr) because it is a standard (non-fast-recovery) silicon bridge rectifier. Its internal diodes are optimized for low conduction loss and high surge capability, not switching speed. For applications requiring t_rr < 500ns - such as high-frequency PFC or resonant topologies - a fast-recovery or ultrafast bridge (e.g., GBU15J or DF08S) should be selected instead. GBPC1510 is intended for line-frequency (50/60 Hz) and low-kHz SMPS rectification where t_rr is not a limiting factor.

Is GBPC1510 RoHS compliant and lead-free?

Yes, GBPC1510 is RoHS compliant and lead-free. The matte tin-plated leads meet J-STD-002 solderability requirements for both SnPb and Pb-free processes, and the molding compound complies with RoHS Directive 2011/65/EU. Certificate of Compliance is available upon request. GBPC1510 contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits, and is suitable for use in consumer, industrial, and medical electronics where RoHS adherence is mandatory.

How is polarity marked on the GBPC1510 package?

GBPC1510 uses a standardized cathode indicator: a white band or "–" symbol printed adjacent to the cathode common terminal (–) on the molded case, located opposite the AC input terminals. The marking diagram confirms the cathode common pin is positioned between the two AC pins, with the anode common (+) pin diagonally opposite. Polarity is also reinforced by physical orientation - the heatsink base is electrically connected to the cathode common terminal, and the case itself serves as the negative output node. GBPC1510's polarity marking conforms to JEDEC MO-127 and ensures unambiguous board-level assembly.
