Vishay Zener Diode 1.5 W 150 V Single Through Hole 2-Pin DO-204AL Z4KE150A-E3/54

Vishay Z4KE150A-E3/54 is a high-quality Zener Diode designed for voltage regulation and stabilization in electronic circuits. This single element diode features a nominal Zener voltage of 150 V and can dissipate up to 1.5 watts of power, making it suitable for various semiconductor applications including automotive electronics.

The diode is mounted through hole using the DO-204AL package, which is a plastic MELF style suited for automated insertion, aiding production efficiency in manufacturing environments. It operates reliably within a wide temperature range from -55°C to 150°C, meeting demanding automotive standards as it is AEC-Q101 qualified.

Key electrical characteristics include a maximum Zener impedance of 1000 Ω which ensures low regulation factor and stable voltage reference under varying loads. The maximum reverse leakage current is limited to 500 nA, minimizing power losses and preventing unwanted currents when reverse biased. A test current of 5 mA defines the operating point for voltage regulation measurements.

Structurally, the diode measures 5.2 mm in length, supporting compact PCB layouts in industrial, automotive, and general electronic assemblies. The product is well suited for voltage regulation circuits, power supplies, and protective voltage reference applications across industrial, laboratory, and automotive sectors.
