47 V shunt regulation with tight ±1% tolerance
The 1N6016D is a 47 V Zener diode from Microchip Technology, specified with a ±1% tolerance on the nominal Zener voltage — this narrow window makes it suitable for precision voltage reference and shunt regulation circuits where the setpoint must stay within 0.47 V of 47 V across the operating range. Rated for 500 mW continuous power dissipation in the DO-35 axial package, the diode handles steady-state bias currents up to roughly 10 mA at 47 V before the junction temperature rise becomes the limiting factor. The 170 Ohm maximum Zener impedance (Zzt) at the test current means the regulation slope is moderate — the output voltage shifts by about 170 mV per mA of load current change.
Thermal and leakage performance across extremes
Reverse leakage is specified at 100 nA maximum when biased at 36 V — well below the Zener knee, so standby power in a voltage-divider bias string stays negligible. Forward voltage is 1.1 V maximum at 200 mA forward current, a typical silicon diode characteristic for the DO-35 package. The through-hole axial lead form factor (DO-204AH, DO-35) suits point-to-point wiring, prototype boards, and replacement in existing designs where the lead spacing matches the original footprint.
