Confirm your project's environmental compliance requirements before committing the line. ## 600 V reverse, 400 mA forward — the rectifier's operating envelope Rated for 600 V DC reverse voltage and 400 mA average rectified forward current, this is a general-purpose rectifier sized for low-current line-frequency rectification — think auxiliary power supplies, snubber networks, or bias rails in industrial control gear. The 1 V forward voltage drop at 400 mA is typical for a standard silicon junction; expect conduction losses around 400 mW at full rated current. Reverse leakage is specified at 50 nA maximum when 600 V is applied — a low-leakage figure that makes this diode suitable for circuits where leakage current could upset a bias point or drain a battery in standby. ## Standard recovery — not for fast switching The recovery speed is classified as standard recovery, with a reverse recovery time greater than 500 ns at a forward current above 200 mA. This is a slow-switching rectifier — it is designed for 50/60 Hz mains-frequency rectification, not for high-frequency switch-mode power supplies where a fast-recovery or ultrafast diode would be required. In a 100 kHz SMPS, the reverse recovery losses would be excessive; keep this part in line-frequency or DC applications. ## DO-35 axial — through-hole integration Housed in the DO-204AH (DO-35) axial-lead package, this diode is a through-hole component. The axial leads are intended for point-to-point wiring, PCB through-hole mounting, or terminal-strip assembly. The DO-35 body is compact — roughly 4.5 mm long by 2.0 mm diameter — so it fits in tight layouts where a larger DO-41 or DO-201 package would not. The tape-and-reel option supports automated insertion for volume production.","metaTitle":"Microchip 1N649-1/TR Diode, 600V 400mA DO-35, Active","metaDescription":"Microchip Technology 1N649-1/TR general-purpose rectifier, 600 V reverse, 400 mA forward, DO-35 axial.
