GBP310

Overview

The GBP310 is a single-phase standard recovery bridge rectifier manufactured by Diodes Incorporated. It features glass passivated die construction and is housed in a GBP through-hole package. The device supports a maximum repetitive peak reverse voltage of 1000V and provides an average forward current of 3A at a case temperature of +100°C. Key electrical parameters include a maximum forward voltage of 1.05V at 1.5A, a maximum leakage current of 5µA at rated voltage and +25°C, and a typical junction capacitance of 25pF. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated die construction for reliable operation
• Molded plastic package with UL flammability classification 94V-0
• Matte tin plated leads solderable per MIL-STD-208
• Lead-free finish compliant with RoHS directives

Applications

• Printed circuit board mounting for general power conversion
• Single-phase bridge configurations in AC/DC power supplies
• Industrial electronics requiring high reliability

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging quantity and carrier type. Ensure compliance with applicable regional environmental regulations regarding halogen and antimony content before finalizing procurement specifications.

Selection Notes

Select the GBP310 when a 1000V rating is required for single-phase rectification applications. Evaluate thermal resistance characteristics and derating curves to ensure the average forward current remains within safe operating limits under expected ambient or case temperatures.

Part Context

The GBP310 belongs to the GBP306–GBP310 series of 3A standard recovery bridge rectifiers from Diodes Incorporated. This family shares identical mechanical dimensions and electrical performance profiles, differentiated solely by their maximum repetitive peak reverse voltage ratings ranging from 600V to 1000V.

Replacement Considerations

Cross-reference with GBP306 (600V) or GBP308 (800V) if lower voltage ratings are sufficient for the application. Verify that substitute components maintain the same GBP package outline and pin configuration for direct PCB compatibility.

FAQ

What is the maximum non-repetitive surge current capability?

The GBP310 can withstand a peak forward surge current of 90A for an 8.3ms single half sine wave at TJ = +25°C, and 72A at TJ = +125°C.

Is the GBP310 suitable for automotive applications?

Standard GBP310 units are not automatically qualified for automotive use. Automotive applications require parts specifically qualified to AEC-Q100/101/104/200 standards and manufactured in IATF 16949 certified facilities.

What is the typical thermal resistance from junction to ambient?

The typical thermal resistance from junction to ambient (RthJA) is 20°C/W, measured with the device mounted on a 30mm x 30mm x 1mm copper plate heatsink.
