Taiwan Semiconductor Corporation GBPC35005W

Overview

GBPC35005W from Taiwan Semiconductor is a 35A, 50V glass-passivated quad bridge rectifier in GBPC-W wire-structure package, featuring 1.1V max forward voltage at 17.5A, <5µA reverse leakage at 25°C, and 1.5°C/W junction-to-case thermal resistance - used in AC/DC converters and switching power supplies requiring high surge tolerance and low thermal resistance.

For engineers reviewing the GBPC35005W datasheet, GBPC35005W pinout, GBPC35005W application, or GBPC35005W equivalent, key selection criteria include rated forward current (35A), peak reverse voltage (50V), IFSM surge rating (400A), thermal performance (R_θJC = 1.5°C/W), and GBPC-W mechanical configuration with heatsink-integrated wire leads.

Technical Context

This device integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions for enhanced reliability under repetitive reverse stress. Its GBPC-W package uses matte tin-plated wire leads and an integrally molded heatsink to achieve low thermal resistance (1.5°C/W) and meet UL 94V-0 flammability standards.

Designed for line-frequency and high-efficiency SMPS front-end rectification, GBPC35005W supports continuous operation up to 150°C junction temperature and withstands 8.3ms half-sine surge currents up to 400A, with fusing I²t rating of 664 A²s - validated per JESD201 Class 1A whisker testing and RoHS compliance.

FAQ

What is the maximum junction temperature rating for GBPC35005W?

The GBPC35005W has a maximum junction temperature (T_J) of +150°C, verified across its full operating range. This rating allows continuous 35A conduction at elevated ambient temperatures when paired with appropriate heatsinking. The device also supports storage from –55°C to +150°C. Thermal design must respect the 1.5°C/W junction-to-case resistance to avoid exceeding this limit in real-world GBPC35005W deployments.

Does GBPC35005W have UL recognition?

Yes, GBPC35005W is UL Recognized under File #E-326243, confirming compliance with UL 60950-1 and UL 62368-1 for use in information technology and audio/video equipment. This recognition covers the GBPC-W package construction, including its UL 94V-0 molding compound and matte tin-plated leads - essential for end-product safety certification involving GBPC35005W.

What is the forward voltage specification for GBPC35005W at rated current?

The GBPC35005W specifies a maximum forward voltage (V_F) of 1.1 V at 17.5 A and 25°C junction temperature, measured per diode under pulsed conditions (PW = 0.3 ms). This value reflects conduction loss per diode pair in the bridge; total bridge drop remains within 2.2 V under full-load conditions, directly impacting efficiency and thermal design of the GBPC35005W-based power stage.

How does the GBPC-W package differ from GBPC-M and GBPC variants?

The GBPC-W package uses wire leads oriented perpendicular to the heatsink plane, enabling direct bolt-down mounting and simplified mechanical integration in chassis-mounted power supplies. In contrast, GBPC-M features parallel terminals for PCB edge-mounting, and standard GBPC uses inline leads. All share the same die, thermal resistance (1.5°C/W), and electrical specs - making GBPC35005W ideal where mechanical flexibility and heatsink coupling are prioritized over automated assembly.

Is GBPC35005W compliant with RoHS and lead-free soldering standards?

Yes, GBPC35005W is RoHS compliant and features matte tin-plated leads qualified per J-STD-002 for solderability. It passes JESD201 Class 1A whisker testing, ensuring reliability under thermal cycling and long-term storage. The device supports lead-free reflow profiles (peak ≤260°C) and is compatible with standard SnPb and Pb-free soldering processes - critical for GBPC35005W integration into modern manufacturing lines.
