Standard recovery >500 ns means it is not intended for high-frequency switching or fast-recovery circuits — it belongs in 50/60 Hz line-frequency rectification or DC bus freewheeling where reverse recovery time is not the limiting parameter. ## Junction temperature and reverse leakage Operating junction temperature spans -65°C to 175°C, which covers military/aerorage thermal profiles and high-reliability derating — the 175°C ceiling gives margin above the 150°C typical for industrial-grade parts. Reverse leakage is specified at 50 nA max at 600 V — low enough for high-impedance bias circuits where leakage current would otherwise shift the operating point. ## Through-hole DO-35 package — legacy board compatibility Supplied in a DO-35 axial leaded package (DO-204AH) with through-hole mounting — the same footprint as the 1N914/1N4148 signal diodes, making it a drop-in for existing PCB layouts that require the higher voltage rating. Forward voltage is 1 V max at 400 mA, which is typical for a standard-recovery silicon rectifier of this current class. ## RoHS non-compliant — check your exemption The 1N649-1 is marked RoHS non-compliant — it does not carry the lead-free plating or exemption status that newer designs require. This limits the part to legacy BOMs with a RoHS exemption, military contracts that explicitly allow tin-lead termination, or repair stock where the original design predates the restriction.","metaTitle":"Microchip 1N649-1 Diode, 600V 400mA DO-35, Active","metaDescription":"Microchip 1N649-1 general-purpose rectifier, 600V 400mA, standard recovery >500ns, DO-35 axial.
