18 V Zener with tight tolerance and wide temperature range
The 1N6006D is an 18 V Zener diode rated for 500 mW continuous power dissipation in the DO-35 axial package. The ±1% tolerance on the nominal Zener voltage makes it suitable for precision voltage reference or clamping applications where a standard ±5% part would drift outside the design window. The 42 Ohm maximum Zzt impedance at the test current means the regulation slope is modest — the output voltage shifts about 42 mV per mA of load change through the knee.
Reverse leakage and forward drop — bench-fit checks
Reverse leakage is specified at 100 nA maximum at 14 V reverse voltage (78% of the nominal Zener voltage). This is low enough that the part does not load a high-impedance bias network in standby circuits.
