5408 General Purpose Rectifier LRM Diode

LRM 5408 General Purpose Rectifier Diode (1N5408) — 3A | 1000V | DO-201AD

The LRM 5408 (also known as 1N5408) is a high-performance, general-purpose silicon rectifier diode built for demanding power electronics applications. With a maximum forward current of 3 Amperes and a peak reverse voltage of 1000 Volts, this diode is engineered for reliable AC-to-DC conversion in a wide range of circuits.

Whether you are building a power supply, AC adapter, inverter, or battery charger, the LRM 5408 delivers stable, low-leakage performance in a rugged axial DO-201AD package, making it a trusted choice for engineers, students, and electronics hobbyists across India.

Key Specifications

Features & Benefits

High Voltage Blocking — Handles up to 1000V reverse voltage, making it safe for mains-connected and industrial circuits.

High Surge Current Tolerance — Can withstand peak surge currents of up to 200A, protecting your circuit against transient spikes.

Low Forward Voltage Drop — A forward voltage of just 1.2V at 3A minimizes power loss and heat generation in your design.

Low Reverse Leakage — Minimal leakage current (10µA) ensures energy efficiency and reduces unnecessary power draw in standby circuits.

Rugged Axial Package (DO-201AD) — Through-hole mounting for easy manual and PCB assembly. Compatible with standard perfboards and prototype boards.

Wide Temperature Range — Operates reliably from -55°C to +150°C, suitable for both indoor and industrial environments.
