Product details

The STPS30M80CT from STMicroelectronics is a dual common-cathode Schottky rectifier in a through-hole TO-220-3 package. The forward drop is specified at 745 mV at 15 A, which directly sets the conduction loss in high-current OR-ing, flyback, or boost stages.

Fast recovery and leakage — switching and standby trade-offs

Listed as a fast-recovery Schottky (≤ 500 ns), this diode handles switching frequencies typical of 50–100 kHz PFC and DC-DC converters without excessive reverse-recovery loss. Reverse leakage is 40 µA at 80 V, a figure to factor into standby-power budgets in always-on supplies.

Frequently asked questions

What is the maximum junction temperature of STPS30M80CT?

The maximum junction temperature is 175°C, which allows operation in high-temperature environments such as enclosed power supplies and motor drives.

What is the difference between STPS30M80CT and STPS30L80CT?

The STPS30L80CT is a lower forward-voltage variant (typically 630 mV at 15 A) compared to the STPS30M80CT's 745 mV at 15 A. The trade-off is higher reverse leakage in the L80CT, so the M80CT is preferred where lower standby current matters at elevated temperatures.

Is STPS30M80CT RoHS compliant?

The STPS30M80CT is listed as RoHS compliant per STMicroelectronics' standard lead-free plating for TO-220 packages. No exemption applies.
