75 V regulation with ±1% precision
The 1N6021D is a 75 V Zener diode from Microchip Technology, specified with a ±1% tolerance on the nominal voltage — this means the regulation point stays between 74.25 V and 75.75 V across the operating range, tight enough for precision reference rails in analog and mixed-signal circuits.
Power handling and temperature range
Rated for 500 mW maximum power dissipation in a DO-35 axial-lead package (DO-204AH), the part handles continuous Zener current up to about 6.7 mA at 75 V before hitting the power ceiling — the 265 Ohm max impedance (Zzt) at the test current means the dynamic resistance adds about 1.8 V of regulation shift from zero to full load.
Through-hole DO-35 axial package — the 0.020-inch diameter leads solder into standard 0.035-inch plated through-holes. The body length is about 0.166 inches; lead spacing is non-critical because the leads are formed during assembly. No MSL rating applies to hermetic glass packages — no bake required before reflow or wave solder.
