Product details

120 V Zener in DO-35 — parametric summary

The 1N6026A is a 120 V Zener diode in the standard DO-35 axial-lead package, rated for 500 mW continuous power dissipation and built for a -65°C to 175°C operating range. Tolerance is ±10% — typical for general-purpose voltage regulation and clamping where a tight reference is not required. Maximum Zener impedance (Zzt) is 1.25 kOhms, which sets the dynamic resistance at the test current; for a fixed bias current, the regulation voltage shifts by this value per milliamp of current change. Reverse leakage is specified at 100 nA maximum at 76 V (63% of Vz), confirming the junction is cleanly blocking well below breakdown. Forward voltage drop is 1.1 V max at 200 mA — usable as a rectifier in a pinch, though the 500 mW power limit restricts continuous forward current.

Frequently asked questions

What does the ±10% tolerance mean for circuit design?

A ±10% tolerance on the 120 V nominal means the actual Zener voltage can range from 108 V to 132 V at the specified test current. This is adequate for general-purpose clamping and rail regulation but not for precision references requiring tighter bands (e.g., ±2% or ±5%).
