Product details

150 V, 15 A Schottky pair in a fully insulated tab

The STPS30150CFP from STMicroelectronics is a dual common-cathode Schottky rectifier rated for 150 V reverse voltage and 15 A average forward current per diode. The 920 mV forward voltage at 15 A sets the conduction-loss floor for a centre-tapped secondary rectifier or an OR-ing diode in a redundant power supply.

Forward drop and leakage at the thermal limits

At the rated 15 A per diode, the 920 mV forward drop is the number you use for the I²R conduction loss in the heatsink calculation. The reverse leakage at 150 V is 6.5 µA at 25 °C — but in a Schottky, leakage doubles every 10–15 °C above the reference. At 125 °C junction, expect that leakage to rise into the milliamps, which adds a standing loss term that can dominate the thermal budget in a lightly loaded or standby rail. The TO-220FP full-pack package means the tab is electrically isolated, so you bolt it directly to the chassis or heatsink without an insulating pad — one fewer BOM line and no assembly step for the washer.

Frequently asked questions

Is STPS30150CFP RoHS compliant and lead-free?

Yes, the STPS30150CFP is ROHS3 compliant, which covers all current RoHS exemption categories. No lead in the solder terminations or plating.

What is the maximum junction temperature of STPS30150CFP?

The maximum junction temperature is 175 °C. This is higher than the typical 150 °C ceiling for a 150 V Schottky, giving additional thermal margin in high-ambient or confined spaces.

What is the difference between STPS30150CFP and STPS30150?

The STPS30150CFP is the fully insulated TO-220FP (full-pack) variant. The base STPS30150 is a standard TO-220 with a non-isolated tab that requires an insulating washer for grounded heatsink mounting. Electrically the die is the same — 150 V, 15 A per diode, same forward drop and leakage.
