82 V Zener with ±1% tolerance — DO-35 axial
The 1N6022D is an 82 V Zener diode from Microchip Technology, rated for 500 mW continuous power dissipation in a DO-35 axial through-hole package. Its ±1% tolerance on the nominal Zener voltage makes it suitable for voltage reference or clamping circuits where tighter regulation is needed than the standard ±5% grade offers.
Temperature range and leakage
Operating from -65°C to 175°C, this diode covers the full military temperature band — useful for avionics, downhole instrumentation, or engine-bay electronics where the ambient exceeds 125°C. Reverse leakage is specified at 100 nA maximum when biased at 62 V, which is well below the Zener knee and confirms the junction quality for low-power standby circuits. Maximum forward voltage is 1.1 V at 200 mA, a typical silicon diode drop that matters when the part is used as a bidirectional clamp or in series with a supply rail.
