1N4745A BK TIN/LEAD

Overview

The Central Semiconductor Corp 1N4745A BK TIN/LEAD is a silicon Zener diode designed for voltage regulation. It features a nominal Zener voltage of 16 V with a 5% tolerance, tested at 15.5 mA. The device dissipates 1.0 W at 50°C and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a maximum reverse current of 5.0 μA at 12.2 V and a maximum DC current of 12.2 mA. It utilizes the DO-41 through-hole package.

Feature Summary

Provides stable voltage regulation using silicon Zener technology
Features a hermetically sealed glass body in a DO-41 axial leaded package
Supports high operating temperatures up to +200°C

Applications

Industrial equipment voltage regulation
Commercial power supply circuits
Computer system protection
Entertainment electronics control

Procurement Notes

Verify the specific ordering suffix 'BK TIN/LEAD' to confirm the tin/lead plating option required for your assembly process. Confirm that the component meets RoHS exemptions if applicable, as standard tin/lead finishes are not RoHS compliant. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity and traceability of the Central Semiconductor product.

Selection Notes

Select this component when a 16 V reference is needed in a through-hole design. The DO-41 package suits standard PCB mounting. Verify that the 1.0 W power dissipation rating aligns with the thermal environment. Consider the 5% voltage tolerance for circuit precision requirements. Ensure the operating temperature range covers the intended application extremes.

Part Context

This part belongs to the 1N47xxA series of 1-watt silicon Zener diodes manufactured by Central Semiconductor. The series spans voltages from 3.3 V to 100 V. These devices are widely used as voltage references and regulators. The 1N4745A specifically targets the 16 V segment of this broad portfolio.
