1N2823B Description

Short technical summary and product information.

The 1N2823B is a Zener diode from Microchip Technology designed for voltage regulation and overvoltage protection applications. It provides a nominal Zener voltage of 30V with a tolerance of ±5%, ensuring reliable voltage clamping. The device can handle a maximum power dissipation of 50W, making it suitable for medium-power circuits. Electrical characteristics include a maximum impedance of 3Ω at the Zener test current, a maximum reverse leakage current of 10µA at 22.8V, and a maximum forward voltage of 1.5V at 10A. The operating temperature range spans from -65°C to 175°C, allowing use in harsh environments. The diode is housed in a through-hole TO-204AD (TO-3) package, which offers robust mechanical mounting and good thermal performance. Applications include power supply regulation, voltage reference circuits, and transient suppression in industrial and automotive systems.
