The STMicroelectronics STPS5L60U is a 5 A, 60 V Schottky rectifier in a surface-mount DO-214AA (SMB) package. It is designed for low-voltage, high-frequency rectification in switch-mode power supplies, freewheeling diodes, and polarity protection. The key parametric trade-off: a forward voltage of 520 mV at the full 5 A rating keeps conduction losses low, while the reverse leakage of 220 µA at 60 V is typical for a Schottky of this voltage class — expect leakage to rise with junction temperature, which matters for standby power budgets in always-on equipment.
Package and thermal — DO-214AA SMB footprint
The SMB footprint is a standard JEDEC outline, compatible with common SMB pad layouts. The junction temperature is rated to a maximum of 150 °C — thermal derating for the 5 A average current should be calculated against the board's copper area and ambient temperature, as the SMB package's thermal resistance depends heavily on PCB heatsinking.
For procurement, this removes the obsolescence risk on new designs and allows standard lead-time planning. The base product number is STPS5, indicating a family of 5 A Schottky rectifiers with various voltage and package options.
