onsemi 1N749ATR is a 4.3V Zener diode with a 500mW power rating. This through-hole component, housed in a DO-35 package (DO-204AH), offers a ±5% voltage tolerance. It exhibits a typical reverse leakage current of 2 µA at 1V and a maximum Zener impedance of 22 Ohms. The forward voltage drop is a maximum of 1.5V at 200mA. Operating across a wide temperature range of -65°C to 200°C, this device is suitable for voltage regulation and reference applications in industrial and consumer electronics. The part is supplied in Cut Tape packaging.
