BZX55C18-TR Description

Short technical summary and product information.

The Vishay BZX55C18-TR is a small signal Zener diode from the BZX55 series, designed for voltage stabilization. It features a nominal Zener voltage of 18V with ±5% tolerance and a power dissipation of 500mW. The diode offers a low reverse leakage current of 100nA at 13V and a maximum forward voltage of 1.5V at 200mA.

 

With a dynamic resistance (Zzt) of 50Ω, this diode provides stable voltage regulation. It operates over a wide temperature range from -65°C to 175°C, with a maximum junction temperature of 175°C. The device is suitable for general purpose voltage reference and clamping applications.

 

The BZX55C18-TR is packaged in a DO-35 (DO-204AH) axial leaded package, designed for through-hole mounting. It is rated UL 94 V-0 for flammability and has MSL level 1 moisture sensitivity. The component weighs approximately 125mg and is available in tape and reel packaging with 10,000 units per reel.
