1N4741A TR PBFREE

Overview

The Central Semiconductor Corp 1N4741A TR PBFREE is a silicon Zener diode designed for voltage regulation. It features a nominal Zener voltage of 11 V with a 5% tolerance, operating within a range of 10.45 V to 11.55 V. The device dissipates up to 1.0 W at 50°C and withstands temperatures from -65°C to +200°C. Packaged in the DO-41 axial leaded case, it exhibits a maximum Zener impedance of 8.0 Ω at the test current of 23 mA and maintains a reverse leakage current of no more than 5.0 μA.
