TRU COMPONENTS 1581947 is a Zener diode, model number TC-ZPY20, housed in a DO-41 package. It is designed for applications requiring voltage regulation, featuring a nominal Zener voltage of 20 V and a maximum power dissipation of 1.3 W. Engineered for use in electronic circuits, this diode serves as a stabilising device, ensuring consistent voltage levels by allowing current to flow backwards when a specified voltage threshold is exceeded. It is suitable for a range of applications including voltage-stabilising circuits, overvoltage protection, and as a reference voltage source. The device's robust construction and precise performance provide reliability in demanding environments often encountered in industrial and commercial electronics. https://elecena.pl/product/29499215/tru-components-1581947-zener-diode-20-v-do-41-1-3-w-tc-zpy20 2025-11-11 https://elecena.pl/product/29499215/tru-components-1581947-zener-diode-20-v-do-41-1-3-w-tc-zpy20 2026-07-23
