20 V Zener with tight ±1% tolerance
The 1N6007D is a 20 V Zener diode from Microchip Technology, specified with a ±1% tolerance on the nominal voltage — this is a tighter band than the standard ±5% grade, so the regulation point is known within 200 mV without binning or test correlation. Rated for 500 mW continuous power dissipation in a DO-35 axial package, the part suits low-current voltage reference and clamping applications where board space is limited and through-hole assembly is preferred.
Temperature range and reverse leakage
Reverse leakage is specified at 100 nA maximum at 15 V reverse voltage, which is 75% of the nominal Zener voltage — this gives a clean knee characteristic for precision shunt regulators where leakage current would otherwise shift the reference point.
