1N5343B-TP

Single Zener Diodes Overview

The MCC 1N5343B-TP is a 5-watt Zener diode housed in the DO-15 axial through-hole package. It provides a nominal Zener voltage of 7.5 V with a tolerance of ±5%. The device operates within a junction temperature range of -55°C to +200°C, though DC conditions are limited to 150°C. Key electrical parameters include a maximum reverse leakage current of 10 µA at 5.7 V and a dynamic impedance of 1.5 Ω. It supports a maximum regulator current of 630 mA and withstands surge currents up to 10.7 A.

Single Zener Diodes Procurement Notes

Verify component authenticity by purchasing exclusively from Micro Commercial Components or their authorized distributors. Ensure compliance with RoHS directives and confirm that the specific ordering suffix matches the required packaging format, such as tape and reel or bulk box quantities, prior to finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 7.5 V regulated output is required with a 5 W power rating. Consider the DO-15 package dimensions for board layout constraints. Evaluate the thermal environment to ensure the junction temperature remains within the specified limits during continuous operation, accounting for the derating curve provided in the datasheet.

Single Zener Diodes Part Context

This part belongs to the 1N5338B through 1N5388B series of 5-watt Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 5.1 V to 200 V, all sharing similar physical characteristics and thermal properties defined by the DO-15 axial leaded package standard.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N5343B equivalents in the DO-15 package. Verify that substitute parts meet the same 5 W power dissipation, 7.5 V nominal voltage, and ±5% tolerance specifications to ensure functional compatibility.
