The 1N6676 is a Schottky barrier diode from Microchip Technology, rated for 200 mA average rectified current (Io) with a 30 V maximum DC reverse voltage (Vr). Forward voltage drop is 500 mV maximum at 200 mA forward current — the Schottky junction keeps conduction losses low in a small-signal rectifier or freewheeling application. Reverse leakage is specified at 10 µA when biased at 30 V, and junction capacitance measures 50 pF at 0 V bias and 1 MHz — both figures matter for high-impedance or fast-switching circuits where the diode's parasitic loading affects the signal.
Housed in a DO-204AH (DO-35) axial-leaded package, the 1N6676 mounts through hole — the glass-sealed body and tin-plated copper leads are a standard footprint for point-to-point wiring or PCB insertion alongside other axial components. Supplied in bulk packaging, the part is suited for hand-assembly or low-volume production runs where tape-and-reel feed is not required.
No pin-compatible alternative is documented from the original manufacturer — a board-level substitution would require requalification against the Schottky's forward drop and capacitance profile.
