Zener regulation at 11 V with tight ±1% tolerance
The 1N6001D is an 11 V Zener diode from Microchip Technology, specified with a ±1% tolerance on the nominal voltage — this tighter window suits voltage-reference applications where a standard ±5% part would drift outside the regulation band.
Leakage and forward characteristics for circuit bias
Reverse leakage is specified at 100 nA maximum when biased at 8.4 V, well below the Zener knee — this low leakage keeps the diode from loading the reference node in high-impedance divider networks. Forward voltage is 1.1 V maximum at 200 mA forward current, consistent with standard silicon diode drop; the 18 Ω maximum Zener impedance (Zzt) at the test current indicates the dynamic resistance near the regulation point.
