1N4148 Signal Diode
Fast small-signal switching diode in DO-35 glass package. Forward voltage ~0.6–0.7 V at low current, reverse breakdown 75 V, max forward current 300 mA, reverse recovery time 4 ns.
Pinout
- ANODE
Anode terminal (positive terminal, marked end without band). Current flows anode→cathode when forward biased.
Type · data - CATHODE
Cathode terminal (negative terminal, marked with black/silver band on DO-35 body). In D1: cathode connects to OPAMP_IN_NEG. In D2: cathode connects to OPAMP_OUT.
