1N4748A TR PBFREE

Overview

The Central Semiconductor Corp 1N4748A TR PBFREE is a silicon Zener diode designed for voltage regulation in industrial, commercial, entertainment, and computer applications. It features a nominal Zener voltage of 22 V with a 5% tolerance range spanning from 20.90 V to 23.10 V. The device operates at a test current of 11.5 mA and dissipates up to 1.0 W of power at 50°C ambient temperature. It utilizes the DO-41 axial leaded package and supports an operating and storage temperature range from -65°C to +200°C.

Feature Summary

Provides stable voltage regulation within a tight 5% tolerance band
Capable of handling high thermal loads with a maximum power dissipation of 1.0 watt
Engineered for extended operational reliability across extreme temperature environments

Applications

Industrial control systems
Commercial electronic equipment
Entertainment system circuitry
Computer hardware components

Procurement Notes

Verify that the specific ordering suffix matches the required plating configuration. The PBFREE designation indicates lead-free compliant terminals, whereas TIN/LEAD variants require explicit specification during procurement. Confirm the reel packaging format aligns with automated assembly requirements before finalizing orders.

Selection Notes

Select this component when a precise 22 V reference point is required for low-noise regulation tasks. Ensure the circuit design accommodates the specified maximum reverse leakage current and impedance values under varying thermal conditions. Verify that the DO-41 footprint is compatible with the target printed circuit board layout.

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 broad voltage spectrum from 3.3 V to 100 V, all sharing identical mechanical outlines and maximum rating profiles within the DO-41 case style.
