STPS30170CT

Diode Arrays Overview

The STPS30170CT is a dual common cathode Schottky rectifier from the STPS40170C series, manufactured by STMicroelectronics. It features a peak repetitive reverse voltage (Vrrm) of 170 V and a maximum continuous forward current (If) of 20 A per diode. The device utilizes a TO-220 package with three pins for through-hole mounting. Key electrical parameters include a maximum forward voltage (Vf) of 920 mV at rated current, a peak non-repetitive forward surge current (Ifsm) of 250 A, and a maximum reverse leakage current (Ir) of 30 μA. It operates within a junction temperature range of -65°C to 175°C.

Diode Arrays Procurement Notes

Verify the specific suffix 'CT' against the manufacturer's official datasheet to confirm the exact pinout configuration and packaging variant. Ensure that the required thermal management solutions are compatible with the TO-220 through-hole form factor. Cross-reference the part number with authorized distributors to confirm current availability status and lead times, as inventory levels may fluctuate based on production schedules.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for synchronous rectification or free-wheeling duties in medium-power applications. The 170 V rating suits lower voltage bus systems, while the 20 A current capacity supports moderate load requirements. Consider the TO-220 package for ease of manual assembly or heatsink integration where surface mount space is limited.

Diode Arrays Part Context

This device belongs to the STPS40170C series of Power Schottky rectifiers. These components are engineered to provide an optimal trade-off between leakage current and forward voltage drop. The series is characterized by its high reliability and compliance with environmental standards such as ECOPACK 2, making it suitable for industrial and consumer electronics requiring efficient power conversion.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include STPS40170CT and STPS60170CT, which share similar voltage ratings but offer different current capacities. Verify compatibility with existing PCB footprints and thermal design constraints before substitution.
