The ±5% tolerance on the nominal voltage is the standard grade for general-purpose voltage reference and clamping applications where tighter binning is not required. Maximum impedance (Zzt) is 1.25 kOhms at the test current — this figure governs the change in Zener voltage with load current and should be factored into the regulation budget for circuits drawing variable current through the diode. ## Temperature range and leakage profile Reverse leakage at 114 V (76% of Vz) is specified at 100 nA maximum — this low standby current suits battery-powered or high-impedance bias networks where every nanoamp matters. Forward voltage drop is 1.1 V maximum at 200 mA forward current, a typical figure for a silicon Zener of this voltage class and useful if the diode is also used as a signal clamp or rectifier in the same assembly. Microchip Technology lists the 1N6028B as Active (current production).","metaTitle":"Microchip 1N6028B Zener Diode, 150 V, 500 mW, DO-35","metaDescription":"1N6028B Zener diode from Microchip Technology, 150 V nominal, 500 mW, ±5% tolerance, DO-35 axial package.
