STPS2L30AFN

STPS2L30AFN Description

The STPS2L30AFN from STMicroelectronics is a Schottky diode designed for high-efficiency rectification in fast-switching applications. With a 30V reverse voltage (Vr) and 2A average rectified current (Io), it offers low forward voltage drop (450mV @ 2A) and ultra-fast recovery (<500ns), minimizing power losses and improving thermal performance. Packaged in an SMAflat Notch (surface-mount), it is optimized for space-constrained PCB designs while ensuring robust performance in demanding environments. Its RoHS3 compliance and REACH-unaffected status make it suitable for modern eco-conscious designs.

STPS2L30AFN Features

• Low Vf (450mV @ 2A): Enhances efficiency by reducing conduction losses.
• Fast Recovery (<500ns): Ideal for high-frequency switching (e.g., DC-DC converters).
• High Junction Temp (150°C): Reliable operation in thermally challenging conditions.
• Low Reverse Leakage (200µA @ 30V): Improves power efficiency in standby modes.
• SMAflat Notch Package: Compact footprint with superior thermal dissipation.
• RoHS3 & REACH Compliant: Meets stringent environmental regulations.

STPS2L30AFN Applications
