DZ2W03000L Description

Short technical summary and product information.

The Panasonic DZ2W03000L is a 3V Zener diode designed for voltage regulation and surge absorption circuits. It offers 1W total power dissipation when mounted on a standard ceramic PCB, with a maximum junction temperature of 150°C.

Key electrical characteristics include a nominal Zener voltage of 3V at 20mA with ±5% tolerance, a low zener impedance of 120Ω, and a forward voltage of 1.2V at 200mA. The reverse leakage current is limited to 150µA at 1V reverse voltage. The device also features a temperature coefficient of -1.7 mV/°C and can handle non-repetitive reverse power surges up to 100W.

The DZ2W03000L is housed in a surface mount SOD-123F package (Mini2-F3-B) suitable for automated assembly. It operates over an ambient temperature range of -40°C to +85°C and can be stored from -55°C to +150°C. The component is halogen-free and RoHS compliant, with an MSL rating of Level 1.
