Schottky barrier for low-voltage rectification
The STPS1L30U is a Schottky diode rated for 30 V reverse voltage and 1 A average rectified current, with a forward voltage of 395 mV at 1 A.
The STPS1L30U is listed as obsolete. No official successor or direct cross-reference is recorded from STMicroelectronics.
Package and footprint — SMB (DO-214AA)
Supplied in the SMB (DO-214AA) surface-mount package. The land pattern is the same as standard SMB Schottky diodes from multiple manufacturers, which simplifies board-level substitution for repair or last-time-buy fills.
Fast recovery characteristic
Rated as fast recovery — ≤ 500 ns at > 200 mA forward current. This switching speed is adequate for line-frequency rectification and moderate-speed switching supplies; for higher-frequency converters a faster Schottky (sub-10 ns) would be needed.
