Product Description

Product model: SR220 to SR2100

Schottky barrier rectifier

Product Overview

The SR220 to SR2100 series are high‑performance Schottky barrier rectifiers, specifically designed for low‑voltage, high‑frequency applications, and offer the following key advantages:

Low forward voltage drop : Significantly reduces power loss and improves efficiency (e.g., the forward voltage of SR220 is reduced to 0.45V ).
High current capability : Supports a forward current of 2.0A, meeting high-load requirements.
High reliability : It adopts the JEDEC DO-15 package and meets the UL 94 V-0 flame-retardant rating.
Wide operating temperature range : Support -65℃ to +175℃ Extreme environment.

Typical Applications

Low-voltage high-frequency inverter
Free-Continuation Current Circuit
Polarity protection device
Switching Power Supplies and Power Management Modules
