UHF8JT-E3/45

Single Diodes Overview

The UHF8JT-E3/45 is a high voltage ultrafast rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an oxide planar chip junction and is housed in an ITO-220AC package with two pins. The device supports a maximum repetitive peak reverse voltage of 600 V and a maximum average forward rectified current of 8 A. It exhibits a typical reverse recovery time of 25 ns and a peak forward surge current capability of 80 A. The component operates within a temperature range of -55 °C to +175 °C.

Single Diodes Feature Summary

• High forward surge current capability
• Solder dip compatibility at 260 °C for 40 seconds

Single Diodes Applications

• High voltage continuous mode power factor correctors (CCM PFC)
• Switching mode power supplies
• Freewheeling diodes
• Secondary DC-to-DC rectification applications

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package variant, as the E3/45 designation corresponds to the ITO-220AC form factor. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement. Ensure thermal management requirements align with the specified junction-to-case thermal resistance values provided in the datasheet.

Single Diodes Selection Notes

Select this component for circuits requiring fast switching speeds and high voltage isolation. The ITO-220AC package provides electrical isolation between the terminal and heatsink, which is critical for certain mounting configurations. Evaluate the thermal resistance and derating curves to ensure the junction temperature remains within the specified operating range under expected load conditions.

Single Diodes Part Context

This part belongs to the UH(U)F8JT series of high voltage ultrafast rectifiers from Vishay. It shares similar electrical ratings with the UH8JT variant but utilizes an insulated TO-220AC (ITO-220AC) package. This insulation allows for direct mounting to heatsinks without additional insulating hardware, distinguishing it from standard non-insulated TO-220 packages.

Single Diodes Replacement Considerations

The UH8JT-E3/45 is a functional substitute if the circuit does not require electrical isolation between the case and the heatsink. Verify that the replacement part meets the same voltage, current, and reverse recovery time specifications.
