Product details
Overview
GBPC3501W from Taiwan Semiconductor is a 35A, 100V glass-passivated single-phase bridge rectifier in GBPC-W wire-structure package, featuring 1.1V max forward voltage at 17.5A, <5µA reverse leakage at 25°C, and 400A peak surge current capability; used in AC-DC conversion stages of industrial power supplies.
For engineers reviewing the GBPC3501W datasheet, GBPC3501W pinout, GBPC3501W application, or GBPC3501W equivalent, key selection criteria include rated forward current (35A), repetitive peak reverse voltage (100V), thermal resistance (1.5°C/W), and GBPC-W mechanical mounting configuration with integral heatsink.
Technical Context
This discrete bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with glass-passivated junctions for enhanced reliability under thermal cycling and humidity stress. Its quad-diode topology delivers unidirectional DC output from AC input without external biasing or control logic.
The GBPC-W variant uses wire-structured terminals oriented perpendicular to the heatsink base, enabling vertical PCB mounting with direct case-to-heatsink thermal coupling. Junction-to-case thermal resistance is fixed at 1.5°C/W, supporting continuous 35A conduction up to 150°C junction temperature when properly heatsinked.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 35 A - Continuous average DC output current capability at case temperature ≤75°C |
| Repetitive Peak Reverse Voltage (VRRM) | 100 V - Maximum AC input peak voltage the device blocks without breakdown |
| Peak Forward Surge Current (IFSM) | 400 A - Short-duration (8.3ms half-sine) overload tolerance during power-up or fault events |
| Forward Voltage (VF) | ≤1.1 V - Voltage drop per diode at 17.5A, defining conduction loss and thermal load at rated current |
| Junction-to-Case Thermal Resistance (RθJC) | 1.5 °C/W - Enables precise heatsink sizing; 52.5W dissipation yields +78.75°C rise above heatsink temperature |
| Reverse Leakage Current (IR) | ≤5 µA - Low off-state power loss critical for high-efficiency SMPS standby modes |
Pinout & Package
GBPC3501W uses the GBPC-W package: a molded plastic case with integral aluminum heatsink base and four wire-terminated leads (two AC inputs, one DC+ output, one DC− output). Mounting is via two 5.59mm-diameter holes on 24.5mm centerline; polarity marked by cathode indicator on heatsink surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 / AC2 | AC Input Terminals | Accept bidirectional AC line input; internally connected to opposite anode/cathode pairs of the bridge |
| + | DC Positive Output | Full-wave rectified positive output node; electrically tied to cathodes of both upper diodes |
| − | DC Negative Output | Full-wave rectified negative output node; electrically tied to anodes of both lower diodes |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Prevents moisture ingress and metallization corrosion, extending operational life in humid industrial environments |
| Integrally molded heatsink | Reduces thermal interface layers-no thermal pad or paste required for basic conduction cooling |
| UL Recognized (E-326243) | Validates flammability (UL 94V-0), terminal solderability (J-STD-002), and whisker resistance (JESD 201 Class 1A) |
| Low IR (<5 µA) | Minimizes no-load power loss in offline adapters and standby power circuits |

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 | Same GBPC package, identical 35A/100V ratings, but GBPC (not GBPC-W) with parallel-terminal configuration | Requires horizontal PCB mounting; incompatible with vertical heatsink interfaces designed for GBPC-W | Select GBPC3501 only if existing layout uses parallel terminals and case-mounting orientation matches |
| ON Semiconductor GBU3501 | GBU package (smaller footprint, 22.5mm × 18.5mm), same 35A/100V specs, RθJC = 2.0°C/W | Higher thermal resistance demands larger heatsink or derating to 28A at 75°C case temp | Choose GBU3501 where board space is constrained but thermal margin allows higher RθJC |
Compared with GBPC3501 and GBU3501, GBPC3501W offers superior thermal performance (1.5°C/W vs. 2.0°C/W) and vertical wire-termination for direct heatsink clamping-critical for high-power density industrial designs where airflow is limited.

FAQ
What is the maximum junction temperature for GBPC3501W?
The GBPC3501W has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the Taiwan Semiconductor datasheet. Operation at this limit requires strict thermal design-case temperature must be maintained below 75°C at 35A DC load to stay within the 1.5°C/W RθJC limit. Exceeding TJ = 150°C risks permanent parametric shift or catastrophic failure. GBPC3501W must be mounted to a heatsink capable of dissipating ≥52.5W under worst-case ambient conditions.
Does GBPC3501W require a heatsink for 35A operation?
Yes, GBPC3501W requires a heatsink for continuous 35A operation. With a junction-to-case thermal resistance of 1.5°C/W and typical conduction loss of ~39W (35A × 1.1V), the case temperature would exceed 150°C without external cooling. The integral heatsink base is designed for direct mounting to an external heatsink using the two 5.59mm mounting holes; thermal interface material is optional but recommended for optimal transfer.
What does the "W" suffix mean in GBPC3501W?
The "W" suffix in GBPC3501W denotes the GBPC-W mechanical variant: a wire-structured terminal configuration where the four leads extend vertically from the heatsink base, enabling vertical PCB mounting and direct clamping to external heatsinks. This differs from GBPC (standard parallel terminals) and GBPC-M (cathode-terminal parallel to anode), and is specified in TSC's ordering code table and package drawings HQ2SD07-GBPCW-056.
Is GBPC3501W RoHS compliant and lead-free?
Yes, GBPC3501W is RoHS compliant and lead-free. The datasheet explicitly states RoHS compliance and specifies matte tin-plated leads meeting J-STD-002 solderability requirements. Terminal finish is Pb-free, and the molding compound satisfies UL 94V-0 flammability standards. No exemptions are applied; full RoHS 2 (2011/65/EU) compliance is confirmed in TSC's product documentation.
What is the reverse recovery time (trr) of GBPC3501W?
The GBPC3501W datasheet does not specify reverse recovery time (trr); it is a standard recovery (non-fast) bridge rectifier optimized for 50/60Hz and low-kHz switching applications-not high-frequency SMPS where trr matters. Its electrical specifications focus on IF, VRRM, IFSM, VF, and IR. For high-frequency rectification (>20kHz), fast-recovery or ultrafast alternatives such as FREDs or SiC diodes should be evaluated instead of GBPC3501W.
