Taiwan Semiconductor Corporation GBPC35005M

Overview

GBPC35005M from Taiwan Semiconductor is a 35A, 50V standard bridge rectifier in GBPC-M package with quad configuration, glass-passivated junctions, and integral heatsink for low thermal resistance (1.5°C/W); used in AC-DC converters and switching mode power supplies requiring high surge capability (400A IFSM) and low leakage (<5µA IR).

For engineers reviewing the GBPC35005M datasheet, GBPC35005M pinout, GBPC35005M application, or GBPC35005M equivalent, key selection factors include peak reverse voltage (50V), average forward current (35A), thermal resistance (1.5°C/W), surge rating (400A), and GBPC-M terminal orientation where cathode is parallel to anode.

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single molded GBPC-M package with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker testing. Its quad configuration delivers full-wave rectification without external interconnection.

The device features glass-passivated junctions for stable reverse leakage (<5µA at rated VR) and high reliability under thermal cycling; its integrally molded heatsink enables direct mounting to chassis or heatsink with maximum torque of 20 in-lbs and UL 94V-0 flammability-rated compound.

FAQ

What is the maximum junction temperature specification for GBPC35005M?

The GBPC35005M has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in high-ambient environments such as enclosed industrial power supplies. Thermal design must ensure actual junction temperature remains below this limit using the specified RθJC of 1.5°C/W and appropriate heatsinking. GBPC35005M must not be operated beyond this thermal limit to avoid parametric shift or premature failure.

Does GBPC35005M meet UL safety standards?

Yes, GBPC35005M is UL Recognized under File #E-326243, confirming compliance with UL 60747-1 and related safety requirements for discrete semiconductors. This recognition applies to the GBPC-M package variant and supports end-equipment certification in North America. The molding compound also meets UL 94V-0 flammability rating. GBPC35005M's UL status is documented in Taiwan Semiconductor's official datasheet revision M2211.

What is the forward voltage drop of GBPC35005M at rated current?

At IF = 17.5A and TJ = 25°C, the typical forward voltage per diode in GBPC35005M is ≤1.1 V, as specified in the Electrical Specifications table. Since it is a full-wave bridge, total conduction loss includes two diode drops in series during each half-cycle. This value is measured under pulse conditions (PW = 0.3ms) and remains stable due to glass-passivated junction technology. GBPC35005M's VF directly impacts conduction efficiency and thermal design in high-current applications.

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

The GBPC-M package features cathode and anode terminals oriented parallel to each other, whereas GBPC-W has them perpendicular. Standard GBPC (unmarked) typically refers to the base GBPC outline without orientation suffix. GBPC35005M's M-suffix explicitly denotes this parallel-terminal configuration, which affects PCB footprint and mechanical mounting. All three share identical electrical ratings and thermal resistance (RθJC = 1.5°C/W), but only GBPC-M matches the mechanical drawing HQ2SD07-GBPCM-055 REV A.

Is GBPC35005M suitable for use in automotive applications?

No, GBPC35005M is not qualified for automotive applications. Taiwan Semiconductor explicitly states in the datasheet notice that "The products shown herein are not designed for use in medical, life-saving, or life-sustaining applications," and no AEC-Q101 qualification or automotive-grade screening is indicated for GBPC35005M. It is intended for industrial, computing, and consumer power supplies. For automotive use, a qualified alternative with AEC-Q101 certification and extended temperature validation would be required instead of GBPC35005M.
