1N5346B-TP

Overview

The MCC 1N5346B-TP is a 5-watt Zener diode with a nominal voltage of 9.1V and ±5% tolerance. It operates in the DO-15 axial leaded package, supporting a maximum DC power dissipation of 5W at 75°C lead temperature. The device features a maximum dynamic impedance of 2Ω and a reverse leakage current of 7.5µA at 6.9V. It withstands a maximum surge current of 0.22A (8.3ms pulse) and maintains an operating junction temperature range from -55°C to +200°C.

Feature Summary

• Provides stable voltage regulation within a wide thermal operating envelope
• Features low thermal resistance for efficient heat dissipation
• Constructed with epoxy meeting UL 94 V-0 flammability ratings

Applications

• Voltage reference circuits
• Overvoltage protection systems
• Power supply regulation

Procurement Notes

Verify component authenticity by purchasing exclusively from Micro Commercial Components Corp or their authorized distributors. Ensure the ordering suffix matches specific requirements, such as adding '-HF' for halogen-free versions. Confirm that packaging formats like Tape & Reel or Ammo Packing align with manufacturing needs before finalizing orders.

Selection Notes

Select this component when a 9.1V regulation point is required with high power handling capabilities. The DO-15 package supports robust through-hole mounting. Consider the thermal derating curve for continuous operation above 75°C lead temperatures. Verify that the 2Ω dynamic impedance meets the circuit's noise and stability specifications.

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 broad voltage range from 5.1V to 200V. The 'B' suffix indicates a standard ±5% voltage tolerance, while the '-TP' suffix designates the specific tape and reel packaging configuration.

Replacement Considerations

Direct substitutes include the onsemi 1N5346BRLG and Diotec Semiconductor 1N5346B. These alternatives share identical electrical characteristics and pinout configurations, facilitating drop-in replacements in existing designs.
