The BZT03C18-TR is a 18V Zener diode from Vishay Dale, part of the BZT03 series designed for medium power voltage regulation and transient suppression. It features a glass passivated junction and hermetically sealed SOD-57 package, providing reliable performance.
Key electrical specifications include a nominal zener voltage of 18V (range 16.9V to 19.1V) at a test current of 25mA, maximum impedance of 15Ω, and reverse leakage current of 1µA at 13V. The forward voltage is 1.2V max at 500mA. Power dissipation is rated at 1.3W at 25°C ambient, with a maximum junction temperature of 175°C.
The through-hole axial package (SOD-57) is suitable for manual or wave soldering, with an MSL level of 1 (unlimited floor life). Applications include voltage regulators, surge protection circuits, and general purpose zener diode functions.
