1N4712 TR TIN/LEAD

Overview

The Central Semiconductor Corp 1N4712 TR TIN/LEAD is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 28V with a power dissipation rating of 0.25W. The component utilizes a DO-35 axial through-hole package and offers a voltage tolerance of ±5%. It operates within a temperature range of -65°C to +200°C junction temperature.

Feature Summary

• Provides stable voltage regulation using unidirectional silicon Zener technology.
• Constructed in a glass-encapsulated DO-35 axial leaded package for through-hole mounting.
• Rated for high junction temperatures up to 200°C.

Applications

• General-purpose voltage reference circuits
• Low-power voltage regulation stages
• Overvoltage protection in signal lines

Procurement Notes

Verify the specific suffix configuration against the manufacturer's current datasheet, as packaging variations such as bulk or tape-and-reel may exist within the same part family. Confirm RoHS compliance status and lead content requirements prior to integration, as tin/lead terminations indicate non-compliant variants for certain jurisdictions.

Selection Notes

Select this component when a 28V regulation point is required in a low-power environment. Ensure the circuit design accommodates the 0.25W thermal limit and that the DO-35 form factor fits the PCB layout constraints. Verify that the ±5% tolerance meets the system's precision requirements.

Part Context

This device belongs to the standard 1N47xx series of Zener diodes manufactured by Central Semiconductor. These components are widely used in discrete electronics for basic voltage clamping and reference duties. The DO-35 package is a legacy but reliable form factor for through-hole assembly processes.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4712 equivalents in DO-35 packages. Verify matching electrical parameters including 28V Zener voltage, 0.25W power rating, and pinout compatibility before substitution.
