1N5346B-AP

Overview

The 1N5346B-AP is a Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 9.1 V with a ±5% tolerance and a maximum power dissipation of 5 W. The device utilizes an axial DO-15 package for through-hole mounting. Key electrical characteristics include a maximum Zener impedance of 2 Ohms, a reverse leakage current of 7.5 µA at 6.9 V, and a forward voltage of 1.2 V at 1 A. The operational temperature range spans from -55°C to 150°C.

Feature Summary

• Provides stable voltage regulation with high precision tolerance
• Capable of handling significant power dissipation in axial packages
• Designed for robust performance across wide temperature extremes

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection in power supply inputs
• Clamping applications in signal conditioning paths

Procurement Notes

Verify the specific suffix AP against official MCC documentation to confirm packaging details and availability status. Ensure compatibility with existing board layouts regarding the DO-15 axial footprint. Confirm RoHS compliance requirements align with project specifications before finalizing procurement orders.

Selection Notes

Select this component when a 9.1 V regulated voltage is required with 5 W power handling capability. The DO-15 axial package suits through-hole assembly processes. Consider the 2 Ohm impedance for dynamic load variations and ensure the thermal environment supports the specified 150°C junction temperature limit during operation.

Part Context

This part belongs to the standard 1N53xx series of high-power Zener diodes produced by Micro Commercial Components. The series is widely recognized for reliable voltage regulation in industrial and commercial electronics. The 1N5346B variant specifically targets applications needing precise 9.1 V references with substantial power margins.

Replacement Considerations

Direct substitutes include the onsemi 1N5346BRL and Diotec Semiconductor 1N5346B. Verify pinout compatibility and thermal resistance values when transitioning between manufacturers to ensure equivalent circuit performance.
