Vishay 18 V 500 mW Voltage Regulator Zener Diode Through Hole 2-Pin SOD-27 TZX18B-TR

Vishay TZX18B-TR Zener Diode is a precision voltage regulator diode featuring an 18 V nominal Zener voltage and 500 mW maximum power dissipation. It is built with a single chip element and housed in a 2-pin SOD-27 package designed for through-hole mounting, suitable for ease of assembly in printed circuit boards.

The diode offers a very sharp reverse characteristic and low noise performance, delivering high stability for voltage regulation in sensitive electronic applications. It operates effectively over a broad temperature range from -65°C to 175°C and supports automotive-grade reliability with AEC-Q101 qualification.

With a test current of 5 mA and a maximum Zener impedance of 55 ohms, this diode ensures precise voltage control with minimal energy loss. The low maximum reverse leakage current of 1 microampere further enhances its efficiency and performance reliability.

This component complies with RoHS environmental standards, making it suitable for modern electronics manufacturing requiring lead-free materials and environmentally friendly processes. The compact 3.9 mm length of the SOD-27 package enables usage in applications where space is limited.

Applications include voltage regulation and protection in industrial equipment, automotive electronics, laboratory instruments, and other commercial and manufacturing electronic systems. Its through-hole mount type facilitates robust mechanical connection and thermal management.
