Product details

650 V, 20 A — the switching power supply workhorse

Its 650 V drain-to-source breakdown voltage provides margin on a 400 V DC bus typical of power-factor-correction stages and offline flyback converters. A gate driver with 1 A to 2 A peak current can switch this device in the 50–100 kHz range without excessive crossover loss.

Through-hole TO-220 — board-level considerations

Housed in a TO-220-3 through-hole package, the STP20NM60A is intended for manual or wave-solder assembly. The tab is the drain terminal, and the metal back provides a low-thermal-resistance path to a heatsink. For rework, the standard TO-220 lead form is compatible with most heatsink clips and mounting holes.

Temperature grade — industrial and automotive environments

The wide range also covers cold-start conditions down to -55°C without derating the drain current below the 20 A continuous rating.

Frequently asked questions

Where can I buy STP20NM60A?

The STP20NM60A is obsolete and no longer stocked by the manufacturer. Submit an RFQ for current availability and pricing; each order is quoted individually.

What is the Vds rating of STP20NM60A?

The drain-to-source voltage rating is 650 V, which gives sufficient headroom for 400 V DC bus applications in power factor correction and offline converters.
