1N4732A TR TIN/LEAD

Overview

The Central Semiconductor Corp 1N4732A TR TIN/LEAD is a silicon unidirectional Zener diode housed in the DO-41 axial through-hole package. It provides a nominal Zener voltage of 4.7V with a power dissipation rating of 1W. The device features a tight voltage tolerance of 1% and operates within a junction temperature range of -65°C to +200°C. This component utilizes tin/lead terminations and is supplied in bulk packaging.

Feature Summary

• High thermal stability supporting operation up to 200°C
• Precision voltage regulation with 1% tolerance
• Robust 1W power handling capability

Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• General-purpose voltage regulation

Procurement Notes

Verify compliance status as the component is identified as non-RoHS compliant. Confirm that the tin/lead termination finish aligns with assembly requirements. Ensure the specific 1% tolerance variant is selected, as standard versions may differ. Validate the DO-41 package dimensions against board layout constraints before procurement.

Selection Notes

Select this part when high precision is required due to its 1% voltage tolerance. The extended 200°C operating temperature makes it suitable for harsh environments. Verify compatibility with existing leaded soldering processes given the tin/lead composition.

Part Context

This component belongs to the 1N47xx series of general-purpose Zener diodes manufactured by Central Semiconductor. It shares the DO-41 form factor common to many axial-lead rectifiers but offers tighter electrical specifications than standard variants.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4732A variants in DO-41 packages. Ensure replacement parts match the 1% tolerance and 1W power rating. Verify terminal material compatibility if lead-free alternatives are required.
