1N5249B TR TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N5249B TR TIN/LEAD is a single silicon Zener diode designed for through-hole mounting in the DO-35 axial package. It features a nominal Zener voltage of 19 V with a ±5% tolerance and a maximum power dissipation of 500 mW. The device exhibits a maximum Zener impedance of 10 ohms and a reverse leakage current of 3 µA at 8.645 to 9.555 V range conditions, though standard datasheets typically specify leakage at lower voltages like 14 V or 17 V depending on the specific test condition defined by the manufacturer. It operates within a temperature range of -65°C to +200°C.
