The SS54 Schottky Diode is a high-performance, 5A 40V surface-mount rectifier designed for power management, reverse polarity protection, and high-efficiency rectification in compact electronic circuits. Housed in a DO-214AC (SMA) package, it offers low forward voltage drop (550mV @ 5A), fast recovery time, and stable performance, making it ideal for DC-DC converters, switching power supplies, battery chargers, and industrial electronic equipment.

Manufactured by MDD and widely used in consumer electronics, embedded systems, and industrial automation, the SS54 diode combines reliability, efficiency, and compact design for surface-mount applications.

Features:

• Schottky barrier rectifier with high efficiency and low forward voltage.

• 40V reverse voltage (Vr) rating and 5A average forward current (Io).

• Fast switching recovery suitable for high-frequency applications.

• Low reverse leakage current (1mA @ 40V).

• Surface mount SMA package (DO-214AC) for compact PCB integration.

• Wide operating junction temperature: -55°C to +125°C.

• High durability and stable performance for industrial and consumer electronics.
