Taiwan Semiconductor Corporation GBPC2501M

Overview

GBPC2501M from Taiwan Semiconductor is a 25A, 100V standard bridge rectifier with glass-passivated junctions, integrally molded heatsink, and UL Recognized (E-326243) construction; it delivers 1.1V max forward voltage at 12.5A and <5µA reverse current at rated VR, used in AC–DC converters and switching mode power supplies.

For engineers reviewing the GBPC2501M datasheet, GBPC2501M pinout, GBPC2501M application, or GBPC2501M equivalent, key selection criteria include peak repetitive reverse voltage (100V), average forward current (25A), thermal resistance (1.5°C/W), surge rating (300A @ 8.3ms), and GBPC-M package mounting configuration.

Technical Context

The GBPC2501M implements a quad-diode full-wave bridge configuration in a single-molded GBPC-M package with cathode terminal parallel to anode, enabling direct PCB-mount heat transfer via its integrally molded heatsink. Its glass-passivated junction ensures stable leakage performance (<5µA IR) across -55°C to +150°C operating range.

Thermal design is supported by a low junction-to-case thermal resistance of 1.5°C/W, allowing sustained 25A conduction under forced-air or heatsink-cooled conditions. The device meets JESD201 Class 1A whisker resistance and UL 94V-0 flammability requirements for industrial-grade reliability.

Key Specifications

Pinout & Package

GBPC2501M uses the GBPC-M package: a 4-terminal, single-in-line molded housing with cathode terminal oriented parallel to anode, matte tin-plated leads compliant with J-STD-002 solderability, and integrated heatsink structure for direct thermal coupling to PCB copper or external heatsink.

FAQ

What is the maximum repetitive peak reverse voltage (VRRM) for GBPC2501M?

The GBPC2501M has a VRRM rating of 100 V, meaning it can reliably block up to 100 volts of reverse voltage in repetitive AC cycles without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the Taiwan Semiconductor datasheet (Version M2211), and aligns with the "01" suffix in the ordering code indicating 100V rating. Exceeding this voltage risks irreversible junction failure in GBPC2501M.

Does GBPC2501M require a heatsink for 25A continuous operation?

Yes - GBPC2501M requires external thermal management for sustained 25A operation. With a junction-to-case thermal resistance of 1.5°C/W and a maximum junction temperature of 150°C, even at 25°C ambient, self-heating exceeds safe limits without heatsinking. The integrally molded heatsink enables direct mounting to a PCB copper pour or external aluminum heatsink, and GBPC2501M's mechanical data specifies 20 in-lbs maximum mounting torque for secure thermal interface.

Is GBPC2501M RoHS compliant and lead-free?

Yes, GBPC2501M is RoHS compliant and features matte tin-plated leads that meet J-STD-002 solderability requirements. It also passes JESD201 Class 1A whisker testing, confirming absence of hazardous substances and mitigation of tin whisker growth. These compliance attributes are explicitly stated in the Features section and Mechanical Data of the Taiwan Semiconductor datasheet (Version M2211) for GBPC2501M.

What does the "M" suffix in GBPC2501M indicate?

The "M" suffix in GBPC2501M denotes the GBPC-M package variant, where the cathode terminal is oriented parallel to the anode terminal - a mechanical configuration optimized for specific PCB layout and heatsink mounting. This differs from GBPC2501 (standard GBPC) and GBPC2501W (wire-lead version). The ordering information table in the datasheet confirms GBPC2501M maps to the GBPC-M package with 50 units per tray.

What is the forward voltage (VF) specification for GBPC2501M at rated current?

GBPC2501M has a maximum forward voltage of 1.1 V per diode at 12.5A forward current and 25°C junction temperature, as specified in the Electrical Specifications table. Since it is a full-wave bridge, total conduction loss is dominated by two diodes in series during each half-cycle, resulting in ~2.2 V total drop at full load - a key parameter for calculating conduction losses and thermal design in GBPC2501M-based power supplies.
