82 V regulation point and thermal budget
The Microchip Technology 1N6022B is an 82 V Zener diode rated for 500 mW maximum power dissipation in a through-hole DO-35 axial package. The 82 V nominal breakdown sets the regulation voltage for clamping, reference, or bias circuits — a common value for high-voltage rail protection or as a shunt reference in 48 V telecom and industrial supplies. At 500 mW and 82 V, the maximum continuous current works out to roughly 6 mA — enough for a low-power reference or a bleeder, but not for heavy shunt regulation. The ±5% tolerance means the actual Zener voltage sits between 77.9 V and 86.1 V, tight enough for most clamping and biasing jobs without bin-sorting.
Temperature range and leakage — field reliability
Reverse leakage is specified at 100 nA maximum at 62 V reverse voltage — low enough that it won't upset a high-impedance bias node or drain a battery in a sleep circuit. Maximum forward voltage is 1.1 V at 200 mA forward current, which matters if the diode sees occasional forward conduction in a bidirectional clamp or rectifier role.
Package and field-swap reality
The DO-35 (DO-204AH) axial package is about as field-service-friendly as it gets — two leads, polarity marked by a cathode band, solderable with a standard iron or even a gas-powered soldering tool in a pinch. No hot-air station, no reflow profile, no orientation ambiguity. It ships in Bulk, so you're not paying for tape-and-reel if you're populating a handful of boards or restocking a repair kit. The 280 Ohm maximum Zener impedance (Zzt) at the test current means the regulation slope is moderate — the voltage shifts a few hundred mV per mA of load change, typical for this power class.
