STPS30170CFP

Diode Arrays Overview

The STPS30170CFP is a dual Schottky rectifier manufactured by STMicroelectronics, designed for high-frequency switch-mode power supplies. It features a common cathode configuration with two anodes housed in a TO-220FP-3 through-hole package. The device supports a maximum repetitive reverse voltage of 170 V and a total average forward current of 30 A (15 A per diode). Key electrical parameters include a maximum forward voltage drop of 950 mV at 30 A and a maximum reverse leakage current of 15 µA at 170 V. It operates within a junction temperature range of -65 °C to +150 °C.

• Free-wheeling diodes in DC-DC converters
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific suffix 'CFP' against the official datasheet to confirm the TO-220FP-3 insulated package variant. Ensure the component meets ECOPACK® 2 compliance requirements if environmental regulations apply. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS status and lead times directly with the supplier before finalizing orders.

Diode Arrays Selection Notes

Select this component when designing circuits requiring a dual Schottky rectifier with a 170 V blocking voltage and 30 A total current capacity. The TO-220FP-3 package provides thermal insulation suitable for heatsink mounting. Consider the trade-off between low leakage current and forward voltage drop inherent to Schottky technology. Verify that the application waveform and peak inverse voltage do not exceed the specified ratings.

Diode Arrays Part Context

This device belongs to the STPS30 series of Power Schottky Rectifiers from STMicroelectronics. The series includes variants with different voltage ratings such as 45 V, 80 V, 120 V, and 150 V, all sharing similar current handling capabilities. The STPS30170CFP specifically addresses higher voltage requirements while maintaining the low switching losses characteristic of the family.

Diode Arrays Replacement Considerations

Publicly confirmed substitutes include the STPS30150CFP for lower voltage applications. Other potential replacements may exist within the same series or from other manufacturers, but direct substitution requires verifying pin compatibility and electrical ratings against the original specifications.
