Product details

Zener voltage, tolerance, and power rating

The 1N6017A: Nominal Zener voltage is 51 V with a ±10% tolerance, so the actual breakdown sits between 45.9 V and 56.1 V — a standard guard band for a 48 V rail clamp or reference. Maximum power dissipation is 500 mW; at 51 V that translates to about 9.8 mA continuous Zener current before derating. The 225 Ohm maximum Zener impedance (Zzt) at the test current means the regulation slope is about 2.2 V per mA of load change — typical for this power class.

Package and temperature range

Supplied in a DO-204AH (DO-35) axial-lead glass package, through-hole mount. The body diameter is about 2.0 mm and the lead spacing fits standard 0.100-inch pitch holes on a prototype board or production PCB.

Reverse leakage and forward drop

Reverse leakage current is specified at 100 nA maximum with 33 V applied across the junction — that is about 65% of the nominal Zener voltage, so the diode stays well below conduction until the avalanche threshold is reached.
