1N4735A BK TIN/LEAD

Overview

The Central Semiconductor Corp 1N4735A BK TIN/LEAD is a single silicon Zener diode designed for through-hole mounting in the DO-41 axial leaded package. It provides a nominal Zener voltage of 6.2 V with a 5% tolerance at a test current of 41 mA. The device dissipates up to 1 W of power and exhibits a maximum reverse leakage current of 10 µA and a Zener impedance of 2 ohms. It operates reliably within an extended temperature range from -65 °C to +200 °C.

Feature Summary

• Provides stable voltage regulation using a single unidirectional silicon junction
• Engineered for high thermal stability with a maximum operating temperature of 200 °C
• Constructed in a robust DO-41 plastic encapsulated axial leaded package

Applications

• General purpose voltage reference circuits
• Overvoltage protection stages
• Power supply regulation modules

Procurement Notes

Verify that the specific suffix indicates tin/lead plating, as this affects RoHS compliance status. Confirm the exact manufacturer designation matches Central Semiconductor Corp specifications. Ensure the ordering code aligns with the required bulk packaging format rather than reel or tape configurations. Cross-reference datasheet electrical limits against circuit requirements before finalizing procurement orders.

Selection Notes

Select this component when a standard 6.2 V regulation point is required in high-temperature environments. The DO-41 package supports manual insertion and automated through-hole assembly processes. Verify that the 1 W power dissipation rating meets the thermal management needs of the target application without requiring additional heat sinking solutions.

Part Context

This part belongs to the widely utilized 1N47 series of general-purpose Zener diodes. The series covers a broad spectrum of voltage ratings from 3.3 V to 100 V, all sharing similar mechanical dimensions and thermal characteristics. The 1N4735A variant specifically targets applications needing precise low-voltage regulation within the standard industrial temperature range.

Replacement Considerations

Equivalent parts include the onsemi 1N4735A and Microchip 1N4735A. These alternatives share identical electrical parameters and the DO-41 footprint. Verify pinout orientation and lead spacing compatibility during substitution.
