That matters when the Zener sets the clamp threshold in a supply rail or the reference in a shunt regulator. Reverse leakage is specified at 100 nA maximum with 52 V applied across the junction — 16 V below the nominal Zener voltage, so the leakage current in the off-state is negligible for most bias networks. At 175°C the leakage climbs, but the glass package keeps the junction dry and stable. ## Impedance and forward drop Maximum Zener impedance (Zzt) is 240 Ohms at the test current — a relatively high figure for a 68 V device, meaning the regulation voltage shifts more with load current than a lower-impedance part. If the load draws variable current, budget the IR drop across this impedance in the output tolerance stack. Forward voltage is 1.1 V maximum at 200 mA forward current — typical for a Zener in this voltage class. The forward drop is not the primary operating mode, but it matters if the diode is used as a bidirectional clamp or in a reverse-polarity protection string. ## Temperature range and reliability Operating junction temperature spans -65°C to +175°C — a military-grade range that covers avionics cold-soak and engine-bay heat alike. The glass DO-35 hermetic seal keeps moisture out, so the Zener holds its leakage spec through thermal cycling that would crack a plastic package.","metaTitle":"Microchip 1N6020C Zener Diode, 68 V, 500 mW, DO-35","metaDescription":"Microchip Technology 1N6020C Zener diode, 68 V nominal, 500 mW, ±2% tolerance, DO-35 axial package.
