onsemi 1SMA5940BT3 is a Zener diode from the 1SMA59xxBT3G series, featuring a 43V nominal Zener voltage and a 1.5W maximum power dissipation. This component is designed for surface mount applications with a DO-214AC, SMA package, supplied on tape and reel. It exhibits a ±5% tolerance for its Zener voltage, with a typical impedance of 53 Ohms at its rated Zener voltage. Reverse leakage is specified at 500 nA at 32.7V. The forward voltage drop at 200mA is a maximum of 1.2V. This device is suitable for power supply regulation and voltage clamping in various electronic systems, including industrial automation and telecommunications infrastructure. Operating temperature range is from -65°C to 150°C.
