Key Features
- Low forward voltage drop of 0.41 V maximum reduces conduction losses in high-efficiency rectifier stages
- 1.0 A / 20 V silicon Schottky rectifier suited for general-purpose switch-mode power supply output stages
- Single-diode DO-216AA (SMD) configuration simplifies PCB layout in space-constrained designs
Applications
The STPS120M is used as an output rectifier in low-power switch-mode power supplies, DC-DC converters, and reverse-polarity protection circuits where its 0.41 V forward drop minimizes power dissipation. Its compact DO-216AA package and 1.0 A / 20 V ratings make it a practical choice for portable electronics and battery charging circuits.

Frequently Asked Questions
What is the forward voltage drop of STPS120M and why does it matter for efficiency?
The STPS120M has a maximum forward voltage drop of 0.41 V at its rated 1.0 A forward current, which is significantly lower than standard PN junction diodes. This reduced conduction loss directly improves power conversion efficiency in switch-mode supplies, especially at higher switching frequencies where rectifier losses dominate.
In which package does the STPS120M come and how does it aid board-level integration?
The STPS120M is housed in a DO-216AA surface-mount package with cathode connection, enabling reflow soldering for automated PCB assembly. The compact SMD footprint minimizes board area, making it suitable for dense portable electronics designs requiring a 1.0 A, 20 V Schottky rectifier.
When should a designer choose STPS120M over a 1 A standard rectifier diode for a 12 V to 5 V converter output?
For a 12 V to 5 V converter, the STPS120M's 0.41 V maximum forward voltage versus the 0.7 V to 1.0 V of standard silicon rectifiers reduces output rectifier power loss by approximately 40–60% at 1.0 A load. This efficiency gain and 20 V reverse voltage rating make it a better choice for high-frequency switching topologies.
