GeneSiC Semiconductor GBPC2504W

Overview

GBPC2504W from Diodes Incorporated is a 25A glass passivated single-phase bridge rectifier with 400V peak repetitive reverse voltage (VRRM), 1.1V forward voltage per element at 12.5A, 300A non-repetitive surge rating, and metal-base heatsink for thermal management-used in AC/DC power supplies for industrial motor drives.

For engineers reviewing the GBPC2504W datasheet, GBPC2504W pinout, GBPC2504W application, or GBPC2504W equivalent, key selection criteria include VRRM derating for capacitive loads, case temperature–dependent current derating, thermal resistance (1.3°C/W junction-to-case), and UL recognition for safety-critical power conversion.

Technical Context

This device integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions to suppress surface leakage and enhance reliability under humid or high-voltage stress conditions. Its internal metal base provides direct thermal conduction path to an external heatsink, enabling sustained 25A average output at TC = 60°C when mounted on a 220 × 220 × 50 mm aluminum plate.

The GBPC2504W operates with 5μA typical reverse leakage at 25°C and 500μA at 125°C under rated DC blocking voltage, supporting stable rectification in ambient temperatures up to +150°C. Its 300pF typical junction capacitance minimizes high-frequency noise coupling in switching power supply front-ends.

FAQ

What is the maximum case temperature for continuous 25A operation?

The GBPC2504W delivers its rated 25A average forward current only when the case temperature (TC) is maintained at ≤60°C, as defined in the derating curve. Exceeding this temperature requires linear current reduction-e.g., at TC = 100°C, IO drops to approximately 15A. Proper heatsinking using the metal base and #10 screw mount is mandatory to sustain full rating.

Does GBPC2504W require a heatsink for 25A operation?

Yes-operation at 25A average current requires mounting on a heatsink. The 1.3°C/W junction-to-case thermal resistance assumes direct metal-to-metal contact with a thermally conductive surface such as a 220 × 220 × 50 mm aluminum plate. Without heatsinking, junction temperature would exceed 150°C even at modest loads, risking thermal runaway.

Can GBPC2504W be used with capacitive input filters?

No-capacitive input filters must be avoided or derated. Per datasheet guidance, average forward current must be reduced by 20% when driving capacitive loads due to increased peak current stress and harmonic heating. For full 25A use, resistive or inductive loads (e.g., choke-input filters) are required to maintain reliability and thermal limits.

Is GBPC2504W compliant with RoHS and REACH regulations?

Yes-GBPC2504W carries lead-free finish and is RoHS compliant per EU Directive 2002/95/EC, with documented exemptions for high-temperature solder and glass components (Annex Notes 5 and 7). It also meets REACH SVHC requirements, with full substance declarations available via Diodes Incorporated's compliance portal.
