BZX84C43LT1G Description

Short technical summary and product information.

The BZX84C43LT1G is a Zener voltage regulator diode from On Semiconductor's BZX84CxxxLT1G series. It offers a nominal Zener voltage of 43V with a ±7% tolerance, making it suitable for precise voltage regulation in a variety of electronic circuits.

With a maximum power dissipation of 250mW on FR-4 or FR-5 boards, this diode is designed for low-power applications. It features a maximum impedance of 150Ω, a reverse leakage current of 50nA at 30.1V, and a typical forward voltage of 900mV at 10mA. The device is rated for an operating temperature range of -65°C to 150°C (junction) and includes an ESD rating of >16kV (Human Body Model).

The diode is housed in a compact SOT-23-3 surface mount package, ideal for high-density PCB designs. It is supplied in tape and reel packaging with 3000 units per reel, optimized for automated assembly. The component is RoHS3 compliant and lead-free, meeting environmental standards.
