1N4754A BK TIN/LEAD

Overview

The Central Semiconductor Corp 1N4754A BK TIN/LEAD is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 39 V with a tolerance of ±5%. The device dissipates up to 1 W of power and operates within a temperature range of -65 °C to +200 °C. Key electrical parameters include a maximum reverse leakage current of 5 µA, a Zener impedance of 125 Ohms, and a test current of 4 mA. It utilizes a DO-41-2 through-hole package.

Feature Summary

• Provides stable voltage regulation at a nominal 39 V level
• Capable of handling 1 W power dissipation in axial leaded packages
• Operates reliably across an extended temperature range from -65 °C to +200 °C

Applications

• Voltage reference circuits requiring 39 V stability
• Overvoltage protection for low-power electronic systems
