1N4758A BK PBFREE

Overview

The Central Semiconductor Corp 1N4758A BK PBFREE is a silicon Zener diode designed for voltage regulation. It features a nominal Zener voltage of 56 V with a 5% tolerance, operating at a test current of 4.5 mA. The device dissipates up to 1.0 W at 50°C and operates within a temperature range of -65°C to +200°C. Electrical characteristics include a maximum reverse current of 5.0 µA and a maximum DC current of 42.6 mA.

Feature Summary

Provides stable voltage regulation using silicon planar technology
Features glass passivation for hermetic sealing and environmental stability
Designed for industrial, commercial, entertainment, and computer applications

Applications

Voltage regulation circuits
Clipping circuits
Industrial equipment power supplies
Computer system protection

Procurement Notes

Verify the specific ordering suffix required for plating configuration. The 'BK' designation indicates bulk packaging, while 'PBFREE' confirms lead-free compliance. Confirm availability status as high-voltage variants in this series may be subject to discontinuation notices or limited stock conditions.

Selection Notes

Select based on the required nominal voltage of 56 V and the 1.0 W power dissipation capability. Ensure the DO-41 axial package fits the board layout constraints. Verify that the operating temperature range meets the application's thermal requirements.

Part Context

This component belongs to the 1N4728A through 1N4764A series of 1-watt silicon Zener diodes manufactured by Central Semiconductor. The series utilizes a DO-41 glass axial package and offers voltages ranging from 3.3 V to 100 V with 5% tolerance.
