100 V zener with 500 mW rating — the thermal budget and regulation accuracy
The 1N6024B is a 100 V zener diode from Microchip Technology in a DO-35 axial package, rated for 500 mW continuous power dissipation. The ±5% tolerance on the nominal voltage means the actual zener voltage sits between 95 V and 105 V at the test current — tight enough for most reference and clamping circuits without requiring a tighter bin. Reverse leakage is specified at 100 nA maximum when the applied voltage is 76 V, which is 76% of the nominal zener voltage. That low leakage keeps standby power draw negligible in circuits where the diode sits across a rail that is below its breakdown threshold.
Active lifecycle — no end-of-line pressure
The DO-35 glass package (DO-204AH) is a through-hole axial-lead form factor that has been a staple in through-hole designs for decades. It is supplied in bulk packaging, which suits hand-assembly or low-volume production runs where tape-and-reel is not required.
