GBPC1508

Overview

The onsemi GBPC1508 is a single-phase bridge rectifier from the GBPC 12, 15, 25, 35 series. It features an average forward current (IF(AV)) of 15 A at a case temperature of 55°C and a maximum repetitive reverse voltage (VRRM) of 800 V. The device has a non-repetitive peak forward surge current (IFSM) rating of 300 A for an 8.3 ms half-sine wave. 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 25°C. Thermal resistance from junction to case is 1.5°C/W with a heatsink. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrally molded heat sink provides very low thermal resistance for maximum heat dissipation.
• Offers isolated voltage from case to lead exceeding 2500 V.
• Terminals are finished with nickel for the standard GBPC package.

Applications

• General-purpose AC to DC power supply circuits
• Battery charging systems
• Industrial motor control applications

Procurement Notes

Verify the specific package variant required, as the datasheet distinguishes between the standard GBPC package with nickel terminals and the GBPC-W variant with wire leads and silver finish. Confirm that the selected part number matches the desired terminal configuration before ordering. Check for discontinuation status if sourcing older revisions.

Selection Notes

Select this component when an 800 V blocking capability and 15 A continuous current are required in a through-hole or screw-mountable form factor. Ensure adequate heatsinking is provided to maintain the junction temperature within limits, given the 1.5°C/W thermal resistance specification. Verify that the surge current requirements do not exceed the 300 A rating.

Part Context

This part belongs to the GBPC 12, 15, 25, 35 series of glass-passivated bridge rectifiers manufactured by onsemi. The series covers various current ratings from 12 A to 35 A and voltage ratings from 50 V to 1000 V. The GBPC1508 specifically addresses the 15 A / 800 V segment of this product family.

Replacement Considerations

Direct substitutes within the same series include GBPC1506 (600 V) or GBPC1510 (1000 V) if voltage margins allow. Other manufacturers offering similar GBPC-form-factor 15 A / 800 V rectifiers may be considered, but pinout and thermal mounting dimensions must be verified.

FAQ

What is the difference between the GBPC and GBPC-W packages?

The GBPC-W package features a wire lead structure with silver-plated terminals suitable for soldering per MIL-STD-208. The standard GBPC package uses nickel-plated terminals and typically employs screw mount or through-hole pin configurations.

Is the GBPC1508 UL certified?

Yes, the GBPC series components are UL Certified under file number E258596.

What is the maximum operating junction temperature?

The maximum operating junction temperature (TJ) for the GBPC1508 is +150°C.
