1N4748A BK TIN/LEAD

Overview

The Central Semiconductor Corp 1N4748A BK TIN/LEAD is a silicon Zener diode with a nominal voltage of 22V and a 5% tolerance. It operates in the DO-41 through-hole package, dissipating up to 1.0W at 50°C ambient temperature. The device features a maximum reverse current of 5.0μA and a dynamic impedance of 23Ω at the test current of 11.5mA. It withstands operating temperatures from -65°C to +200°C.

Feature Summary

Provides stable voltage regulation within a tight 5% tolerance band for precision applications.
Constructed with a hermetically sealed glass body for high reliability and environmental resistance.
Features built-in strain relief and low inductance characteristics suitable for industrial environments.

Applications

Industrial voltage regulation circuits
Commercial power supply protection
Computer system voltage reference

Procurement Notes

Verify the specific ordering suffix 'BK TIN/LEAD' to confirm lead-tin plating availability, as standard RoHS-compliant versions may use different terminations. Confirm current production status directly with Central Semiconductor, as certain series members have transitioned to End-of-Life status. Request official datasheets to validate electrical parameters against your design requirements before finalizing procurement.

Selection Notes

Select this component when a 22V Zener reference is required in a DO-41 glass package. Ensure the circuit can handle the specified 1.0W power dissipation and that the 5% voltage tolerance meets the application's accuracy needs. Verify compatibility with existing PCB footprints designed for axial-lead components.

Part Context

This part belongs to the 1N4728A through 1N4764A series of 1-watt silicon Zener diodes manufactured by Central Semiconductor. The series covers a voltage range from 3.3V to 100V, all sharing the same DO-41 mechanical outline and general reliability standards for voltage regulation tasks.
