Product details

STMicroelectronics lists the STPS16L40CT as obsolete.

At 8 A per diode, the 500 mV Vf is a typical figure for a 40 V Schottky in this current range. That translates to about 4 W conduction loss per diode at full rated current — manageable with a heatsink on the TO-220 tab, but the thermal design needs to account for both diodes conducting simultaneously. The reverse leakage of 700 µA at 40 V is worth noting for standby or low-load conditions: at elevated junction temperatures leakage climbs, so derate the effective current if the ambient is above 85°C.
