30 V regulation with tight ±2% tolerance
The 1N6011C is a 30 V Zener diode from Microchip Technology, specified with a ±2% tolerance on the nominal voltage — tighter than the standard ±5% grade, which matters when the Zener serves as a voltage reference or clamp in a precision bias supply. Rated at 500 mW maximum power dissipation, the part handles continuous shunt regulation up to that limit; derating is required above 25°C ambient, as with any small-signal Zener in a DO-35 package.
Reverse leakage and forward drop
Reverse leakage is specified at 100 nA maximum with 23 V applied across the junction — 7 V below the nominal Zener voltage, so the diode draws negligible current in the off state. This low leakage suits battery-powered monitoring circuits where standby current must stay in the nanoamp range. Maximum forward voltage is 1.1 V at 200 mA forward current, a standard figure for a silicon Zener of this power class.
Temperature range and package
Housed in a DO-204AH (DO-35) axial-lead package, the 1N6011C mounts through-hole on a PCB or protoboard. The axial form factor is still widely used in point-to-point wiring, terminal-strip regulation, and legacy board rework.
