Product details
Overview
GBPC3501 from Taiwan Semiconductor is a 35A, 100V standard bridge rectifier in GBPC package with quad configuration, glass-passivated junctions, 1.5°C/W junction-to-case thermal resistance, and <5µA reverse leakage at rated voltage - used in AC-DC converters and switching mode power supplies.
For engineers reviewing the GBPC3501 datasheet, GBPC3501 pinout, GBPC3501 application, or GBPC3501 equivalent, key selection factors include peak repetitive reverse voltage (100V), average forward current (35A), surge capability (400A @ 8.3ms), thermal performance, and UL recognition (E-326243) for industrial power conversion designs.
Technical Context
This discrete bridge rectifier integrates four silicon diodes in a single molded GBPC package with integral heatsink, enabling high-power AC-to-DC conversion without external thermal management in compact layouts. Its glass-passivated junction ensures stable operation up to 150°C junction temperature and low IR drift over time.
The device supports 100V repetitive peak reverse voltage (VRRM) and delivers 35A average forward current (IF) with 1.1V max forward voltage per diode at rated load. It meets JESD201 Class 1A whisker resistance and UL 94V-0 flammability requirements for safety-critical power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse voltage the bridge withstands without breakdown |
| IF (AV) | 35 A - Continuous average forward current per bridge, defining steady-state power handling |
| IFSM | 400 A - Peak non-repetitive surge current for 8.3 ms half-sine, critical for inrush tolerance |
| RθJC | 1.5 °C/W - Thermal resistance from junction to case, enabling direct heatsink mounting for thermal control |
| IR | <5 µA - Reverse leakage per diode at rated VR, ensuring low standby power loss |
| TJ max | +150 °C - Maximum allowable junction temperature, supporting high-ambient industrial environments |
Pinout & Package
GBPC3501 uses the standard GBPC through-hole package: 4-pin, quad-diode bridge configuration with integrated heatsink base. Cathode and anode terminals are marked on the molded case; polarity follows industry-standard bridge layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 / AC2 | AC Input Terminals | Two alternating current inputs accepting full-wave AC; symmetrical connection enables universal input wiring |
| + (Anode) | DC Positive Output | Rectified positive DC output node; connects to bulk capacitor or downstream regulator input |
| – (Cathode) | DC Negative Output | Rectified negative DC return path; tied to system ground or common reference plane |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBPC3501-E4/51 | Same 35A/100V rating, identical GBPC package, but uses epoxy-molded construction without integral heatsink base | Lacks integrated heatsink; requires external thermal pad or clip for equivalent thermal performance | Choose when board-level heatsinking is already implemented and footprint compatibility is prioritized |
| ON Semiconductor GBPC3501 | Identical electrical specs and GBPC mechanical outline, but RoHS-compliant matte tin plating per J-STD-002 confirmed | No functional difference; validated for same industrial and SMPS use cases | Preferred for new designs requiring full traceability and dual-sourcing assurance from Tier-1 suppliers |
Compared with GBPC3501, the Vishay alternative requires added thermal interface design effort, while the ON Semiconductor version offers identical performance with enhanced supply-chain resilience - both serve as drop-in alternatives only when matching the exact GBPC3501 variant and mounting method.

FAQ
What is the peak repetitive reverse voltage rating of GBPC3501?
The GBPC3501 has a peak repetitive reverse voltage (VRRM) rating of 100 V. This value is specified in the Absolute Maximum Ratings table of the Taiwan Semiconductor datasheet (Version M2211) and defines the maximum reverse voltage the device can block repeatedly without breakdown. It applies across the full operating temperature range and is verified under standard test conditions.
Does GBPC3501 include an integrated heatsink?
Yes, GBPC3501 features an integrally molded heatsink in its GBPC package, resulting in a low junction-to-case thermal resistance of 1.5°C/W. This design eliminates the need for separate heatsink hardware in many applications and allows direct mounting to a metal chassis or PCB copper pour for thermal management - a key differentiator from standard epoxy-packaged bridges.
Is GBPC3501 RoHS compliant and UL recognized?
Yes, GBPC3501 is RoHS compliant and UL Recognized under File # E-326243. These certifications are explicitly stated in the Features section of the official Taiwan Semiconductor datasheet (Version M2211). The device also meets UL 94V-0 flammability requirements and JESD201 Class 1A whisker resistance standards.
What is the forward voltage drop of GBPC3501 at rated current?
The GBPC3501 exhibits a maximum forward voltage (VF) of 1.1 V per diode at 17.5 A forward current and 25°C junction temperature. This value is specified in the Electrical Specifications table and reflects conduction loss under typical operating conditions - critical for calculating total bridge power dissipation and thermal design margins.
How is polarity marked on the GBPC3501 package?
Polarity on GBPC3501 is marked via a cathode indicator - a channeled corner and molded "+" symbol adjacent to the positive output terminal. The AC input terminals are unmarked and symmetrical; the DC output terminals are labeled "+" (anode) and "–" (cathode) on the case surface per the Marking Diagram in the Package Outline Dimensions (Page 4, Version M2211).
