Taiwan Semiconductor Corporation GBPC3510

Overview

GBPC3510 from Taiwan Semiconductor is a 35A, 1000V standard bridge rectifier in GBPC package with quad configuration, glass-passivated junctions, and integrally molded heatsink; it delivers ≤1.1V forward voltage at 17.5A and <5µA reverse current at rated VR, used in high-reliability AC–DC converters and SMPS front-ends.

For engineers reviewing the GBPC3510 datasheet, GBPC3510 pinout, GBPC3510 application, or GBPC3510 equivalent, key selection criteria include peak repetitive reverse voltage (1000V), 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 with cathode/anode terminals externally accessible via four leads. Its glass-passivated junction ensures stable leakage performance (<5µA IR) across -55°C to +150°C junction temperature range.

The GBPC3510 uses an integrally molded heatsink structure achieving 1.5°C/W junction-to-case thermal resistance, enabling direct mounting to external heat sinks without supplemental thermal interface material under rated load conditions.

Key Specifications

Pinout & Package

GBPC3510 uses the GBPC through-hole package with four terminals: two AC input pins (AC1, AC2), one anode (A), and one cathode (K). The package features an integrally molded heatsink base and matte tin-plated leads compliant with J-STD-002 solderability.

FAQ

What is the maximum junction temperature rating for GBPC3510?

The GBPC3510 has a maximum junction temperature (TJ max) of +150°C, validated across its full operating range from -55°C to +150°C. This rating allows sustained operation in high-ambient environments such as enclosed industrial power supplies or convection-cooled server PSUs. Derating curves in the datasheet specify usable current versus case temperature, and thermal design must ensure RθJC (1.5°C/W) and system-level RθCA remain within limits to prevent exceeding TJ max during GBPC3510 operation.

Does GBPC3510 require a heatsink for 35A continuous operation?

Yes, GBPC3510 requires external heatsinking for 35A continuous forward current operation. Its 1.5°C/W junction-to-case thermal resistance assumes direct mounting to a sufficiently sized heatsink; without one, junction temperature will exceed +150°C even at moderate ambient. The integrally molded heatsink base enables mechanical attachment using up to 20 in-lbs torque, and thermal interface material may be omitted if surface flatness and contact pressure meet spec. Always validate with measured case temperature under actual load conditions for GBPC3510.

Is GBPC3510 RoHS compliant and lead-free?

Yes, GBPC3510 is RoHS compliant and features matte tin-plated leads that meet J-STD-002 solderability requirements. It also passes JESD201 Class 1A whisker testing, confirming suitability for long-life, high-reliability applications. The RoHS compliance applies to all homogeneous materials in the device, including molding compound (UL 94V-0 rated) and internal metallization. No lead or lead-based alloys are used in GBPC3510 manufacturing per TSC's declaration and third-party test reports.

What is the reverse recovery time (trr) specification for GBPC3510?

The GBPC3510 datasheet does not specify reverse recovery time (trr) because it is a standard (non-fast-recovery or ultrafast) silicon bridge rectifier. Its design prioritizes high surge current and low leakage over switching speed, making it unsuitable for high-frequency (>20 kHz) switching applications. For circuits requiring fast trr, engineers should select fast-recovery alternatives like GBPC3505F or discrete ultrafast diodes. GBPC3510 is optimized for line-frequency (50/60 Hz) and low-kHz PFC pre-regulator stages where trr is not a limiting factor.

How is polarity marked on the GBPC3510 package?

GBPC3510 uses a standardized polarity marking: a cathode indicator (a white or contrasting band) is located adjacent to the cathode (K) terminal on the molded case, aligned with the chamfered corner of the GBPC package. The anode (A) terminal is diagonally opposite, while AC1 and AC2 are the remaining two leads. Marking code "GBPC3510" appears on the top surface, and the date code (YWW) and factory code (F) follow per TSC's marking diagram. Polarity must be verified visually before PCB placement to avoid reverse-bias damage during initial power-up of GBPC3510.
