Zd10-100 Datasheet [top] Jun 2026

The ZD10-100 is interchangeable with the 1N4740A in most circuits, but always verify the exact impedance and leakage specs from the .

This circuit uses a series resistor (Rs) and the ZD10-100 to produce a stable 10V output from a higher, unregulated DC source. zd10-100 datasheet

The maximum current Izm is derived from Pd / Vz ≈ 1W / 10V = 100mA. Some datasheets derate this at higher ambient temperatures. The ZD10-100 is interchangeable with the 1N4740A in

The power dissipation exceeds 0.5W. Increase the series resistance or use a higher wattage Zener (e.g., 1N5346B – 5W). Check if the load current flows through the Zener instead of the load. zd10-100 datasheet
