Product details
Overview
GBPC3508 from Taiwan Semiconductor is a 35A, 800V standard bridge rectifier in GBPC package with quad configuration, glass-passivated junctions, and integrally molded heatsink for low thermal resistance (1.5°C/W); used in AC-DC converters and switching mode power supplies requiring high surge current capability (400A IFSM) and low reverse leakage (<5µA).
For engineers reviewing the GBPC3508 datasheet, GBPC3508 pinout, GBPC3508 application, or GBPC3508 equivalent, key selection criteria include peak reverse voltage (800V), average forward current (35A), thermal resistance (1.5°C/W), surge rating (400A), and GBPC mechanical footprint compatibility with heatsink mounting.
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration with cathode and anode terminals externally accessible via four leads. The GBPC package features an integrally molded heatsink enabling direct PCB mounting and efficient heat transfer to external heatsinks.
It operates across -55°C to +150°C junction temperature range, supports 8.3ms half-sine surge currents up to 400A, and maintains reverse leakage below 5µA at rated VRRM with forward voltage ≤1.1V per diode at specified test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| IF(AV) | 35 A - Continuous average forward current rating under specified thermal conditions |
| IFSM | 400 A - Peak non-repetitive surge current capability for 8.3ms half-sine waveform |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance enabling effective heatsink coupling |
| VF | ≤1.1 V - Forward voltage drop per diode at 17.5A, 25°C, limiting conduction loss |
| IR | ≤5 µA - Reverse leakage current per diode at rated VRRM and 25°C, ensuring low standby loss |
Pinout & Package
The GBPC3508 uses the GBPC through-hole package with four terminals: two AC input pins (AC1, AC2), one anode (A), and one cathode (K). The package includes an integrally molded heatsink base compatible with standard mounting hardware (max torque 20 in-lbs) and UL 94V-0 molding compound.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBPC3508 | Identical electrical specs (35A/800V), same GBPC package outline, but uses different lead finish (SnPb vs matte tin) and lacks UL E-326243 recognition | Acceptable in non-certified industrial designs; not suitable for UL-listed end equipment requiring recognized components | Select GBPC3508 when UL recognition and RoHS-compliant matte tin plating are required |
| ON Semiconductor GBPC3508 | Same ratings and package, but datasheet specifies higher typical VF (1.15V) and lower I²t rating (600 A²s vs 664 A²s) | Suitable for lower-duty-cycle applications; may require derating in high-surge environments | Prefer Taiwan Semiconductor GBPC3508 for designs demanding maximum surge margin and consistent low VF |
Compared with Vishay and ON Semiconductor equivalents, the Taiwan Semiconductor GBPC3508 delivers superior surge robustness (664 A²s), certified UL recognition, and tighter forward voltage control-critical for thermally constrained, high-reliability AC-DC front ends.

FAQ
What is the maximum junction temperature rating for GBPC3508?
The GBPC3508 has a maximum junction temperature (TJ) rating of +150°C, with operational storage temperature spanning -55°C to +150°C. This wide thermal range enables use in harsh industrial environments where ambient temperatures exceed 85°C, provided thermal design accounts for its 1.5°C/W junction-to-case resistance and proper heatsinking.
Does GBPC3508 have UL recognition?
Yes, GBPC3508 is UL Recognized under File # E-326243, confirming compliance with UL 60747-1 for discrete semiconductors. This recognition supports end-equipment certification in North America and validates safety-related construction, including flammability (UL 94V-0 molding compound) and terminal integrity.
What is the forward voltage specification for GBPC3508?
The GBPC3508 has a maximum forward voltage (VF) of 1.1 V per diode at IF = 17.5 A and TJ = 25°C, measured under pulse conditions (PW = 0.3 ms). This low VF reduces conduction losses in high-current rectification stages, directly improving overall power supply efficiency and thermal management margins.
How is polarity marked on the GBPC3508 package?
Polarity on the GBPC3508 is indicated by a cathode marker-a chamfered corner and "K" marking adjacent to the cathode (K) terminal on the package body. The anode (A) and AC input terminals are positioned symmetrically opposite, with AC1 and AC2 labeled per standard GBPC marking diagram (YWWF format).
What mounting torque is recommended for GBPC3508?
The recommended maximum mounting torque for GBPC3508 is 20 in-lbs (2.26 N·m) when securing the integrally molded heatsink to an external heatsink or chassis. Exceeding this value risks cracking the epoxy molding compound or damaging internal wire bonds, potentially compromising thermal performance and long-term reliability.
