STPS10170CT

Diode Arrays Overview

The STPS10170CT is a dual common cathode Schottky rectifier manufactured by STMicroelectronics. It features a peak repetitive reverse voltage (Vrrm) of 170 V and a maximum average forward rectified current (If) of 10 A per anode. The device utilizes a TO-220-3 through-hole package with a center tab for thermal management. Key electrical characteristics include a maximum forward voltage drop (Vf) of 1 V at rated current, a peak non-repetitive forward surge current (Ifsm) of 120 A, and a low reverse leakage current (Ir) of 2 µA. It operates within a junction temperature range of -65°C to +175°C.

Diode Arrays Feature Summary

• Dual common cathode configuration suitable for high-frequency switched mode power supplies
• High junction temperature capability up to 175°C for enhanced reliability
• Optimized trade-off between low leakage current and forward voltage drop

Diode Arrays Applications

• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific ordering suffix against official STMicroelectronics documentation to confirm pinout and packaging details. Ensure the procurement channel provides genuine components with traceable manufacturing data. Cross-reference the part number with the latest datasheet revision to confirm compliance with RoHS and REACH standards before finalizing orders.

Diode Arrays Selection Notes

Select this component when designing circuits requiring a 170 V blocking voltage and 10 A continuous current capacity in a through-hole format. The TO-220-3 package facilitates effective heat dissipation via a mounting heatsink. Consider the low forward voltage drop for efficiency optimization and the high surge current rating for robustness against transient loads in power conversion applications.

Diode Arrays Part Context

This device belongs to the STPS10170C series of dual Schottky rectifiers from STMicroelectronics. The series is engineered for general-purpose power rectification where low loss and high speed are critical. The TO-220-3 variant specifically addresses applications needing robust mechanical mounting and efficient thermal transfer compared to surface-mount alternatives.

Diode Arrays Replacement Considerations

Direct replacements must match the 170 V Vrrm, 10 A If, and TO-220-3 package constraints. Verify that alternative dual common cathode Schottky diodes offer comparable Vf and Ir specifications to maintain circuit efficiency and thermal performance without redesigning the PCB footprint.
