Taiwan Semiconductor Corporation GBPC1501W

Overview

GBPC1501W from Taiwan Semiconductor is a 15A, 100V glass-passivated quad bridge rectifier in GBPC-W wire-structure package, featuring 1.1V max forward voltage at 7.5A, <5µA reverse leakage at 25°C, and 300A peak surge current - used in AC/DC converters and switching power supplies.

For engineers reviewing the GBPC1501W datasheet, GBPC1501W pinout, GBPC1501W application, or GBPC1501W equivalent, key selection criteria include rated reverse voltage (100V), thermal resistance (1.5°C/W), mounting torque limit (20 in-lbs), and UL recognition (E-326243) for industrial power conversion designs.

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single molded GBPC-W package with integral heatsink, enabling high-efficiency AC-to-DC conversion without external heat sinking under moderate load conditions. Its glass-passivated junction ensures stable reverse characteristics and low IR drift over temperature.

The device operates across -55°C to +150°C junction range, supports 8.3ms half-sine surge events up to 300A, and maintains <1.1V forward drop per diode at rated DC output current - critical for minimizing conduction loss in compact SMPS front-end stages.

FAQ

What is the maximum junction temperature rating for GBPC1501W?

The GBPC1501W has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows reliable operation in high-ambient environments such as enclosed power supplies or industrial control cabinets. Thermal design must ensure actual junction temperature remains below this limit under worst-case load and ambient conditions. GBPC1501W's 1.5°C/W RθJC supports this with appropriate heatsinking.

Does GBPC1501W have UL recognition?

Yes, GBPC1501W is UL Recognized under file #E-326243, confirming compliance with UL 60950-1 and UL 62368-1 for use in end-product safety certifications. This applies to the entire GBPC15, 25, 35 series including the GBPC-W variant. The recognition covers flammability (UL 94V-0 molding compound), terminal plating (J-STD-002 solderability), and mechanical construction - all documented in Taiwan Semiconductor's M2211 datasheet revision.

What does the "W" suffix indicate in GBPC1501W?

The "W" suffix in GBPC1501W denotes the GBPC-W package variant: a wire-structure terminal configuration where leads extend radially from the base of the molded case, differing from the standard GBPC (parallel terminals) and GBPC-M (cathode terminal perpendicular to anode). This geometry facilitates vertical mounting and simplified through-hole insertion in high-density layouts. Mechanical drawings confirm distinct lead spacing and heatsink cutout dimensions unique to GBPC-W.

What is the forward voltage specification for GBPC1501W?

The forward voltage (VF) for GBPC1501W is specified as ≤1.1 V per diode at IF = 7.5 A and TJ = 25°C, per the Electrical Specifications table in the Taiwan Semiconductor datasheet. This value reflects typical conduction loss under nominal load and is measured using a 0.3ms pulse test. At elevated temperatures or higher currents, VF increases slightly - design margins should account for up to 1.2 V in worst-case thermal conditions.

How is polarity marked on the GBPC1501W case?

GBPC1501W uses a cathode indicator - a molded cathode symbol ("K") or stripe adjacent to the cathode terminal - located on the heatsink surface near the cathode lead. The marking diagram in the datasheet (page 5, Version M2211) confirms this location and specifies that polarity follows standard bridge rectifier convention: two AC inputs (AC1/AC2), one common anode (+), and one common cathode (–). The cathode terminal is electrically connected to the heatsink base.
