GBPC1504W

Overview

The onsemi GBPC1504W is a single-phase bridge rectifier from the GBPC 12, 15, 25, 35 series. It features a maximum repetitive reverse voltage (VRRM) of 400 V and an average rectified forward current (IF(AV)) of 15 A at a case temperature of 55°C. The device has a non-repetitive peak forward surge current (IFSM) rating of 300 A for an 8.3 ms half-sine-wave pulse. Electrical characteristics include a maximum forward voltage drop (VF) of 1.1 V at 7.5 A and a maximum reverse current (IR) of 5.0 μA at rated VR and 25°C. Thermal resistance from junction to case is 1.5°C/W with a heatsink. The component operates within a junction and storage temperature range of -55°C to +150°C.

Feature Summary

• Integrally molded heat sink provides very low thermal resistance for maximum heat dissipation.
• Surge overload ratings support up to 300 A for the GBPC15 series.
• Provides isolated voltage from case to lead exceeding 2500 V.
• Terminals are silver-plated and solderable per MIL-STD-202, Method 208.

Applications

• General purpose power supply circuits
• AC to DC conversion in industrial equipment
• Battery charging systems

Procurement Notes

Verify the specific ordering suffix 'W' corresponds to the wire lead structure variant rather than the standard pin type. Confirm compliance with RoHS directives as these are Pb-Free devices. Check for discontinuation status or alternative recommendations if sourcing for new designs, as some series variants are not recommended for new use. Ensure mounting torque does not exceed 20 in-lbs during installation.

Selection Notes

Select this part based on the required 400 V reverse voltage blocking capability and 15 A continuous current rating. Consider the thermal environment; derating curves must be applied if case temperatures exceed 55°C. Verify that the PCB layout accommodates the GBPC-W package dimensions and terminal spacing. Ensure the application load does not exceed the 300 A surge current limit during startup or fault conditions.

Part Context

This component belongs to the GBPC 12, 15, 25, 35 series of glass-passivated bridge rectifiers manufactured by onsemi. The '15' designation indicates the 15 A current class, while '04' specifies the 400 V voltage rating. The 'W' suffix denotes the wire lead configuration, distinguishing it from the standard pin-mount GBPC package. These devices utilize silicon technology and are designed for high reliability in general-purpose applications.

Replacement Considerations

Direct replacements within the same series include GBPC1504 (pin mount) if the package style change is acceptable. Other manufacturers producing equivalent 15 A, 400 V bridge rectifiers in similar packages may serve as substitutes, provided thermal and electrical parameters match. Verify mechanical fit and terminal finish compatibility before substitution.
