Taiwan Semiconductor Corporation GBPC3502

Overview

GBPC3502 from Taiwan Semiconductor is a 35A, 200V standard bridge rectifier in GBPC package with quad configuration, glass-passivated junctions, and integrally molded heatsink for low thermal resistance (1.5°C/W). It delivers <1.1V forward voltage at 17.5A and <5μA reverse current at rated voltage, used in AC–DC converters and switching mode power supplies.

For engineers reviewing the GBPC3502 datasheet, GBPC3502 pinout, GBPC3502 application, or GBPC3502 equivalent, key selection criteria include peak repetitive reverse voltage (200V), average forward current (35A), surge capability (400A @ 8.3ms), thermal resistance (1.5°C/W), and UL recognition (E-326243).

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration, enabling efficient AC-to-DC conversion without external interconnects. Its glass-passivated junction ensures stable leakage performance (<5μA IR) across temperature, while the molded heatsink structure supports direct PCB mounting with mechanical torque limit of 20 in-lbs.

The device operates over –55°C to +150°C junction range and meets JESD201 Class 1A whisker resistance and UL 94V-0 flammability standards. Electrical behavior follows standard diode conduction and blocking characteristics, with no control logic, timing functions, or programmable features.

FAQ

What is the peak repetitive reverse voltage rating of GBPC3502?

The GBPC3502 has a peak repetitive reverse voltage (VRRM) rating of 200 V. This value is confirmed in the Absolute Maximum Ratings table of the Taiwan Semiconductor datasheet (Version M2211), where "02" in the part number denotes the 200V variant within the GBPC15/25/35 family. It defines the maximum AC voltage the device can block during normal operation without breakdown.

Does GBPC3502 have UL recognition and what is the file number?

Yes, GBPC3502 is UL Recognized under file number E-326243. This certification is explicitly stated in the FEATURES section of the official Taiwan Semiconductor datasheet (Version M2211) and applies to the entire GBPC15/25/35 series, including GBPC3502. It validates compliance with UL 60747-1 for discrete semiconductors.

What is the thermal resistance from junction to case for GBPC3502?

The junction-to-case thermal resistance (R_θJC) of GBPC3502 is 1.5°C/W, as specified in the THERMAL PERFORMANCE section of the Taiwan Semiconductor datasheet (Version M2211). This value reflects the efficiency of heat transfer from the silicon die to the molded heatsink base, enabling direct mounting to chassis or PCB copper without an additional heatsink in many 35A applications.

What does the "02" suffix in GBPC3502 indicate?

The "02" in GBPC3502 indicates the peak repetitive reverse voltage rating of 200 V. Per the ORDERING INFORMATION section of the Taiwan Semiconductor datasheet (Version M2211), the numeric suffix maps to voltage grades: 005 = 50 V, 01 = 100 V, 02 = 200 V, 04 = 400 V, etc. Thus, GBPC3502 is the 35A, 200V variant of the GBPC series.

Is GBPC3502 RoHS compliant and lead-free?

Yes, GBPC3502 is RoHS compliant and lead-free. The datasheet (Version M2211, page 1) states "RoHS Compliant" in the FEATURES section, and the terminal plating is specified as matte tin per J-STD-002, confirming full compliance with Directive 2011/65/EU. No lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE substances exceed threshold limits.
