The 600 V reverse voltage gives it headroom for rectifying 240 VAC or 400 VAC lines with a standard safety margin, while the 600 mA average forward current suits it for low-power DC supplies, relay coil freewheeling, or as a general-purpose signal diode in military-grade assemblies. ## Military screening and temperature range Qualified to MIL-PRF-19500/587, this diode carries the screening and lot-acceptance requirements of a JAN-level device — the date-code trace and marking consistency matter more here than with a commercial-grade part. Reverse leakage is specified at 50 nA maximum at the 600 V rated voltage, a tight figure for a standard recovery part that indicates good junction quality. ## Recovery speed and where it fits Listed as standard recovery with a reverse recovery time greater than 500 ns at 200 mA forward current. This places it firmly in the 50/60 Hz line-frequency rectification class — it is not intended for switch-mode power supplies running at tens of kilohertz. In a 400 Hz aerospace power bus or a 50 Hz industrial control transformer secondary, the stored charge in the junction is not a concern; the diode recovers slowly but the zero-crossing gives it time. For a high-frequency flyback or PFC stage, a fast or ultrafast recovery part would be needed. ## Package and procurement reality Supplied in the DO-204AH (DO-35) axial-lead glass package, a through-hole form factor that hand-solders or wave-solders into legacy and high-reliability boards. The TR suffix indicates Tape & Reel packaging — the diode body is oriented for automated insertion or hand-kitting. Microchip lists the lifecycle as Active, meaning no EOL notice or last-time-buy window is currently open.","metaTitle":"Microchip 1N6663/TR Standard Recovery Diode","metaDescription":"1N6663/TR from Microchip Technology: 600V 600mA standard recovery diode, MIL-PRF-19500/587 qualified, DO-35 axial package.
