Product details

150 V, 1 A Schottky — obsolete but still in the channel

The STMicroelectronics STPS1150M is a 150 V, 1 A Schottky rectifier in the DO-216AA STmite surface-mount package. It carries a fast-recovery characteristic (≤ 500 ns, > 200 mA) typical of Schottky technology, with a forward voltage drop of 820 mV at the rated 1 A forward current.

For a BOM that requires this exact diode, procurement must turn to independent distribution — surplus, new-old-stock reels.

820 mV Vf at 1 A — thermal budget check

At 1 A forward current the STPS1150M exhibits 820 mV typical forward drop. That translates to roughly 820 mW of dissipation — manageable in the STmite package if the board has adequate copper spreading, but tight for a compact design without airflow. The 175°C junction rating provides headroom, but the thermal resistance of the DO-216AA means the trace-connected cathode tab is the primary heat path.

Frequently asked questions

Can I use the STPS1150M in a high-temperature application?

Yes, the maximum junction temperature is 175°C, which qualifies it for under-hood automotive or industrial environments where ambient temperatures exceed 125°C. The 1 µA reverse leakage at 150 V is specified at 25°C; expect leakage to increase with temperature, so derate accordingly.
