Schottky barrier diode for low-power, fast-switching service
The 1N6857-1 is a 20 V, 150 mA Schottky rectifier in the DO-35 axial-lead package, built for small-signal service where switching speed and low forward drop matter more than raw current capacity. With a 750 mV typical forward drop at 35 mA and 150 nA reverse leakage at 16 V, the 1N6857-1 suits low-voltage rail isolation, polarity protection, and high-frequency detector circuits where every millivolt of drop counts.
Key parametrics for the BOM decision
Rated for 20 V DC reverse (Vr max) and 150 mA average rectified output (Io), this Schottky is sized for low-current signal paths and auxiliary bias supplies, not main power rectification. Capacitance is 4.5 pF at 0 V bias and 1 MHz, low enough to avoid loading RF detector or fast-switching logic outputs.
Supplied in the DO-204AH (DO-35) axial-lead package, through-hole mount, with bulk packaging — the standard form factor for point-to-point wiring and through-hole PCB assembly.
