The Microchip Technology 1N3328B is a 43V Zener diode designed for high-power applications. This component features a robust DO-5 (DO-203AB) stud mount package, facilitating chassis mounting for effective thermal management. With a maximum power dissipation of 50W and a ±5% voltage tolerance, it provides stable voltage regulation across a wide operating temperature range of -65°C to 175°C. The diode exhibits a Zener impedance (Zzt) of 4.5 Ohms maximum at its nominal voltage. Typical applications include voltage regulation and surge suppression in industrial power supplies, automotive systems, and telecommunications infrastructure. Reverse leakage current is rated at 10 µA at 32.7V.
