Taiwan Semiconductor Corporation GBPC35005

Overview

GBPC35005 from Taiwan Semiconductor is a 35A, 50V standard bridge rectifier in GBPC 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 reverse leakage (<5µA).

For engineers reviewing the GBPC35005 datasheet, GBPC35005 pinout, GBPC35005 application, or GBPC35005 equivalent, key selection factors include rated forward current (35A), repetitive peak reverse voltage (50V), thermal resistance (1.5°C/W), surge rating (400A), and GBPC mechanical outline compatibility with heatsink mounting.

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with common cathode and anode terminals. Its glass-passivated junction ensures stable reverse characteristics and low IR (<5µA at rated VR), while the molded heatsink structure enables direct PCB mounting and efficient heat transfer.

The device operates across -55°C to +150°C junction temperature range and supports 8.3ms half-sine surge currents up to 400A. Forward voltage is specified at 1.1V max per diode under rated DC load conditions (IF = 17.5A, TJ = 25°C), confirming conduction efficiency in high-current AC-DC front ends.

FAQ

What is the maximum junction temperature rating for GBPC35005?

The GBPC35005 has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version M2211). This allows operation in high-ambient environments when properly heatsinked. Derating curves confirm usable current capacity down to 0A at 150°C case temperature. The GBPC35005 must not exceed this limit to maintain reliability and avoid parametric shift.

Does GBPC35005 have UL recognition?

Yes, GBPC35005 is UL Recognized under file #E-326243, as stated in the "Features" section of the Taiwan Semiconductor datasheet (Version M2211). This applies to the entire GBPC15/25/35 family, including GBPC35005, and confirms compliance with UL 60747-1 for discrete semiconductors. The recognition supports end-product safety certification in North America.

What is the forward voltage drop specification for GBPC35005?

The forward voltage (VF) for GBPC35005 is specified as a maximum of 1.1 V per diode at IF = 17.5 A and TJ = 25°C, per the Electrical Specifications table (Version M2211). Since it is a full-wave bridge, total conduction drop across two series diodes is up to 2.2 V under those test conditions. This value directly impacts conduction loss and thermal design in the GBPC35005 application.

Is GBPC35005 RoHS compliant and lead-free?

Yes, GBPC35005 is RoHS compliant and meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements. The terminals are matte tin-plated and solderable per J-STD-002. It also passes JESD201 Class 1A whisker testing. These qualifications are documented in the Mechanical Data section of the Taiwan Semiconductor GBPC15/25/35 datasheet (Version M2211).

What does the "005" suffix indicate in GBPC35005?

The "005" suffix in GBPC35005 denotes the repetitive peak reverse voltage rating of 50 V, per Taiwan Semiconductor's ordering code convention (Version M2211). In the GBPC*x naming scheme, "x" maps to voltage: 005 = 50V, 01 = 100V, 02 = 200V, etc. Thus GBPC35005 is the 35A, 50V variant of the GBPC series, distinct from GBPC3501 (100V) or GBPC3502 (200V).
