1N5348B-TP

Overview

The MCC 1N5348B-TP is a 5-watt Zener diode with an 11V nominal voltage and ±5% tolerance. It operates in the -55°C to +200°C junction temperature range, featuring a maximum dynamic impedance of 2.5Ω at 125mA test current. The device dissipates up to 5W with derating above 75°C and withstands surge currents up to 0.25A.

Feature Summary

• Provides stable voltage regulation within a wide thermal operating envelope
• Features high surge current capability for transient protection applications
• Utilizes epoxy encapsulation meeting UL 94 V-0 flammability standards

Applications

• Voltage reference circuits requiring precise regulation
• Power supply overvoltage protection stages
• Clamping circuits for transient suppression

Procurement Notes

Verify component authenticity by checking markings against official datasheet specifications. Ensure ordering suffixes match required packaging formats such as tape-and-reel or bulk. Confirm RoHS compliance status and halogen-free availability if specific environmental regulations apply to the target assembly process.

Selection Notes

Select this component when a 5-watt power rating and 11V breakdown are required. Consider the DO-15 through-hole package for standard PCB mounting. Evaluate thermal resistance values to ensure adequate heat dissipation under continuous DC load conditions without exceeding maximum junction temperatures.

Part Context

This part belongs to the 1N5338B through 1N5388B series manufactured by Micro Commercial Components. The series covers Zener voltages from 5.1V to 200V in the DO-15 package. The -TP suffix indicates standard tape-and-reel packaging for automated insertion processes.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent 5W, 11V Zener diodes in DO-15 packages. Verify that replacement parts meet identical electrical parameters including dynamic impedance and surge current ratings.
