Product details

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.

Frequently asked questions

Where can I buy STPS1L30U and check current pricing?

The STPS1L30U is obsolete and sourced through independent distribution. Submit an RFQ to confirm availability and current pricing for your quantity; we source and quote to order.

What is the replacement for STPS1L30U?

No official replacement is recorded from STMicroelectronics. For a pin-compatible substitute in the SMB package, evaluate other 30 V, 1 A Schottky diodes with similar forward voltage from ST or alternate manufacturers — verify the forward drop and reverse leakage against your circuit's thermal budget.
