onsemi GBPC25005

Overview

GBPC25005 from Diodes Incorporated is a 25A glass passivated single-phase bridge rectifier with 50V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 12.5A per element, 300A non-repetitive surge rating, and metal-base thermal design for heatsink mounting in AC/DC power supplies for industrial motor drives.

For engineers reviewing the GBPC25005 datasheet, GBPC25005 pinout, GBPC25005 application, or GBPC25005 equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (1.3°C/W junction-to-case), case isolation voltage (1500V), and through-hole screw-mount mechanical interface.

Technical Context

This bridge rectifier integrates four silicon diodes in a single molded plastic package with internal heatsink, configured as a full-wave single-phase AC input to DC output converter. It operates under resistive/inductive loads at 60Hz with mandatory 20% current derating for capacitive loads.

Thermal performance relies on external heatsinking via its metal base and #10 screw mounting; junction temperature must remain within –65°C to +150°C, with forward current derated linearly above TC = 60°C per Figure 1.

FAQ

What is the maximum allowable case temperature for continuous operation?

The GBPC25005 is rated for 25A average output current only when case temperature (TC) is maintained at or below 60°C. Above this, forward current must be linearly derated per Figure 1 in the datasheet, reaching zero at TC = 125°C. Sustained operation above 60°C without derating risks thermal runaway and premature failure.

Can GBPC25005 be used with capacitive loads without modification?

No - the datasheet explicitly requires a 20% reduction in average output current (to 20A) when driving capacitive loads due to high inrush currents that exceed the device's surge rating under repeated cycling. Failure to derate may cause accelerated degradation of the glass-passivated junctions.

Is the metal base electrically isolated from the terminals?

Yes - the case-to-terminal isolation voltage is rated at 1500V RMS, verified per UL Recognized Component File E94661. This allows safe mounting to grounded metal chassis without shorting the negative terminal, provided mounting hardware does not breach the isolation barrier.

What does the "W" suffix indicate in GBPC25005W?

The "W" suffix denotes wire-lead termination (as opposed to fast-on terminals in the standard GBPC25005). GBPC25005W uses tinned copper leads suitable for PCB through-hole soldering or wire-wrap connections, while retaining identical electrical and thermal specifications.
