onsemi GBPC35005

Overview

GBPC35005 from Diodes Incorporated is a 35A glass-passivated single-phase bridge rectifier with 50V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 17.5A per element, and 400A non-repetitive surge current rating; designed for AC/DC conversion in industrial power supplies and motor control input stages.

For engineers reviewing the GBPC35005 datasheet, GBPC35005 pinout, GBPC35005 application, or GBPC35005 equivalent, key selection criteria include thermal resistance (1.2°C/W), case isolation voltage (1500V), mounting torque limit (8.0 in-lb), and derating behavior under capacitive loads.

Technical Context

This device integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions for enhanced reliability and low leakage. It operates across –65°C to +150°C and requires heatsink mounting via #10 screw for thermal management.

The GBPC35005 delivers 35A average rectified output at TC = 50°C with 20% current derating for capacitive loads. Its 300pF typical total capacitance (measured at 1MHz, 4V reverse bias) supports stable switching in line-frequency applications.

FAQ

What is the maximum allowable mounting torque for GBPC35005?

The maximum mounting torque for GBPC35005 is 8.0 inch-pounds when securing the device to a heatsink using a #10 screw. Exceeding this value risks cracking the molded plastic case or compromising internal die attachment, leading to premature thermal failure or electrical leakage.

Does GBPC35005 require derating for capacitive loads?

Yes - the datasheet explicitly requires 20% derating of average output current (IO) when used with capacitive-input filter configurations. This accounts for higher peak currents during capacitor charging cycles, which increase junction temperature beyond resistive/inductive load assumptions.

What is the thermal resistance junction-to-case (RθJC) and how is it measured?

RθJC is 1.2°C/W, measured with the device mounted on a 220 × 220 × 50 mm aluminum heatsink plate. This value reflects thermal conduction from the silicon die junction to the external metal base, and assumes optimal mechanical contact and thermal interface material usage.

Is GBPC35005 compliant with RoHS and lead-free assembly standards?

Yes - GBPC35005 features a lead-free finish and complies with RoHS Directive 2011/65/EU, including approved exemptions for high-temperature solder and glass encapsulation as defined in Annexes V and VII of the EU directive.
