1N5351B-TP

Overview

The MCC 1N5351B-TP is a 5.0 W Zener diode with a nominal voltage of 14 V and ±5% tolerance. It operates in the -55°C to +200°C range, with a maximum DC junction temperature of 150°C. Key electrical parameters include a test current of 100 mA, maximum dynamic impedance of 2.5 Ω at 100 mA, and maximum reverse leakage current of 1 µA at 10.6 V. The device features a DO-15 axial leaded package, 1.2 V forward voltage at 1 A, and supports surge currents up to 6.7 A.

Feature Summary

• Provides stable voltage regulation within a wide operating temperature range
• Features low thermal resistance for efficient heat dissipation
• Utilizes epoxy encapsulation meeting UL 94 V-0 flammability standards

Applications

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

Procurement Notes

Verify compliance with RoHS directives and confirm halogen-free status if required by adding the specific suffix. Ensure sourcing from authorized distributors to guarantee traceability and adherence to quality standards. Check packaging options such as tape and reel or bulk quantities against project requirements.

Selection Notes

Select this component for applications requiring 14 V regulation with 5 W power handling. Consider the 2.5 Ω dynamic impedance for stability needs. Verify thermal management capabilities given the 83°C/W junction-to-ambient resistance. Confirm package compatibility with existing through-hole mounting infrastructure.

Part Context

This part belongs to the 1N5338B through 1N5388B series of 5 Watt Zener Diodes manufactured by Micro Commercial Components. The series covers voltages from 5.1V to 200V in the DO-15 package. The 1N5351B-TP specifically addresses the 14V segment with standard 5% tolerance.

Replacement Considerations

Cross-reference with other manufacturers' 1N5351 equivalents. Verify identical pinout, power rating, and voltage tolerance before substitution.
