Taiwan Semiconductor Corporation GBPC2508W

Overview

GBPC2508W from Taiwan Semiconductor is a 25A, 800V standard bridge rectifier in GBPC-W wire-structure package, featuring glass-passivated junctions, 1.5°C/W junction-to-case thermal resistance, and <5µA reverse leakage at rated voltage - used in high-reliability AC/DC converters and switching mode power supplies.

For engineers reviewing the GBPC2508W datasheet, GBPC2508W pinout, GBPC2508W application, or GBPC2508W equivalent, key selection criteria include peak repetitive reverse voltage (800V), average forward current (25A), surge capability (400A @ 8.3ms), thermal performance, and GBPC-W mechanical mounting configuration.

Technical Context

FAQ

What is the maximum junction temperature rating for GBPC2508W?

The GBPC2508W has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the Taiwan Semiconductor datasheet M2211. This allows sustained operation in high-ambient environments when mounted to an appropriate heatsink. Thermal derating curves show usable current capacity down to 0A at 150°C case temperature. The GBPC2508W must be operated within this limit to ensure reliability and avoid parametric shift.

Does GBPC2508W have UL recognition?

Yes, GBPC2508W is UL Recognized under File # E-326243, as stated in the official Taiwan Semiconductor datasheet M2211. This applies to the entire GBPC15/25/35 series including the GBPC-W variant. UL recognition confirms compliance with UL 60747-1 and supports end-equipment safety certification in North America. The GBPC2508W carries this recognition without additional qualification.

What is the forward voltage drop specification for GBPC2508W?

The GBPC2508W has a maximum forward voltage drop (VF) of 1.1 V per diode at IF = 12.5 A and TJ = 25°C, per the Electrical Specifications table in the M2211 datasheet. This value reflects worst-case conduction loss under typical operating conditions. At higher temperatures or currents, VF increases slightly - the curve data shows ~1.15 V at 12.5 A and 125°C. The GBPC2508W's low VF contributes directly to reduced power dissipation in high-current rectification.

How does the GBPC-W package differ from standard GBPC?

The GBPC-W package features wire-structure terminals instead of flat parallel tabs, enabling direct screw-mounting to heatsinks with improved mechanical stability and thermal contact. Dimensions confirm longer terminal reach and chamfered corner geometry optimized for wire-based fastening. Unlike GBPC-M (cathode-parallel) or standard GBPC, GBPC-W eliminates need for separate mounting hardware. The GBPC2508W leverages this for compact, high-power-density designs where vibration resistance matters.

Is GBPC2508W RoHS compliant and lead-free?

Yes, GBPC2508W is RoHS compliant and lead-free, as explicitly stated in the Features section of the Taiwan Semiconductor M2211 datasheet. It also passes JESD201 Class 1A whisker testing and uses matte tin-plated leads meeting J-STD-002 solderability requirements. All materials and plating processes for GBPC2508W conform to EU Directive 2011/65/EU. No exemptions apply - the GBPC2508W is fully compliant out-of-box.
