Taiwan Semiconductor Corporation GBPC2501

Overview

GBPC2501 from Taiwan Semiconductor is a 25A, 100V standard bridge rectifier in GBPC package with quad configuration, glass-passivated junctions, 1.5°C/W junction-to-case thermal resistance, and <0.2μA typical reverse leakage at 25°C - used in AC-DC converters for industrial power supplies.

For engineers reviewing the GBPC2501 datasheet, GBPC2501 pinout, GBPC2501 application, or GBPC2501 equivalent, key selection factors include peak repetitive reverse voltage (100V), average forward current (25A), surge capability (300A @ 8.3ms), thermal performance, and UL recognition (E-326243) for safety-critical power conversion designs.

Technical Context

This single-package, four-diode full-wave bridge rectifier integrates a molded heatsink to achieve low thermal resistance (1.5°C/W), enabling efficient heat dissipation without external heatsinking in moderate-power applications. Its glass-passivated junction ensures stable reverse characteristics and long-term reliability under thermal cycling.

The device supports high surge current (300A non-repetitive, 8.3ms half-sine) and maintains low forward voltage drop (max 1.1V per diode at rated current), directly reducing conduction losses in switching-mode power supplies and linear AC-DC front-ends.

Key Specifications

Pinout & Package

FAQ

What is the peak repetitive reverse voltage rating of the GBPC2501?

The GBPC2501 has a peak repetitive reverse voltage (VRRM) rating of 100 V. This value defines the maximum AC voltage the device can repeatedly block across its AC terminals without entering avalanche breakdown. It is measured under standard test conditions (TA = 25°C) and aligns with the "01" suffix in the ordering code GBPC2501, indicating the 100V variant within the GBPC25 family. The GBPC2501 must not be operated beyond this voltage in continuous or repetitive mode.

Does the GBPC2501 require an external heatsink for 25A continuous operation?

The GBPC2501 features an integrally molded heatsink with a junction-to-case thermal resistance (RθJC) of 1.5°C/W. At 25A average forward current and 1.1V forward drop, power dissipation is ~27.5W. With proper mounting to a ≥150 cm² aluminum heatsink (RθCA ≈ 5°C/W), case temperature remains within safe limits. For ambient temperatures above 50°C or sustained full-load operation, an external heatsink is strongly recommended - the GBPC2501 is designed for direct heatsink attachment, not standalone PCB operation at rated current.

Is the GBPC2501 RoHS compliant and lead-free solder compatible?

Yes, the GBPC2501 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 suitability for lead-free reflow processes (peak temperature up to 260°C). The molding compound complies with UL 94V-0 flammability standards, and all materials are documented per EU RoHS Directive 2011/65/EU Annex II substance restrictions.

What does the "01" in GBPC2501 signify?

The "01" in GBPC2501 denotes the peak repetitive reverse voltage rating: "01" = 100 V. Per Taiwan Semiconductor's ordering convention, the numeric suffix after "GBPC25" encodes voltage grade - "005" = 50V, "01" = 100V, "02" = 200V, up to "10" = 1000V. Thus, GBPC2501 is the 25A, 100V variant of the GBPC25 series, distinct from GBPC2502 (200V) or GBPC2504 (400V).

How is polarity marked on the GBPC2501 package?

Polarity on the GBPC2501 is indicated by a cathode marker: a channeled corner and printed "–" symbol adjacent to the cathode terminal (common negative output). The marking diagram shows "P/N YWWF", where "YWW" is date code and "F" is factory code; the cathode terminal is electrically connected to the metal heatsink base. Mounting orientation must preserve this marking visibility for correct circuit integration - reversing polarity risks catastrophic failure due to internal diode shorting.
