STPS140AY Description

The STPS140AY from STMicroelectronics is a high-performance Schottky diode designed for fast switching applications with a 40V reverse voltage (Vr) and 1A average rectified current (Io). Packaged in a compact SMA surface-mount form factor, it features ultra-low forward voltage drop (650mV @ 2A) and fast recovery time (<500ns), making it ideal for high-efficiency power conversion. Compliant with AEC-Q101 automotive standards, it ensures reliability in harsh environments. The diode is RoHS3 compliant, REACH unaffected, and rated for MSL 1 (unlimited moisture sensitivity), ensuring robust performance in industrial and automotive applications.

STPS140AY Features

• Low Vf (650mV @ 2A): Minimizes power loss and improves efficiency.
• Fast Recovery (<500ns): Enhances switching performance in high-frequency circuits.
• Automotive Grade (AEC-Q101): Ensures reliability under extreme conditions.
• Low Reverse Leakage (12µA @ 40V): Reduces standby power consumption.
• Surface Mount (SMA): Compact footprint for space-constrained designs.
• RoHS3 & REACH Compliant: Environmentally friendly and globally accepted.

STPS140AY Applications

• DC-DC Converters: Optimizes efficiency in step-up/down voltage regulation.
• Reverse Polarity Protection: Safeguards sensitive circuits in automotive systems.
• Freewheeling Diodes: Used in inductive load switching (e.g., relays, motors).
• Solar Power Systems: Prevents backflow in photovoltaic applications.
• Portable Electronics: Ideal for battery-powered devices due to low Vf.

Conclusion of STPS140AY
