1N5353B-TP

Overview

The MCC 1N5353B-TP is a 5-watt Zener diode with a nominal voltage of 16V and a ±5% tolerance. It operates in the DO-15 axial package, supporting a maximum DC power dissipation of 5W at a lead temperature of 75°C. The device features a maximum dynamic impedance of 2.5 Ohms and a reverse leakage current of 1µA at 12.2V. It withstands a maximum surge current of 30A for an 8.3ms pulse width. The junction-to-lead thermal resistance is 15°C/W, allowing operation up to +200°C under pulsed conditions.

Feature Summary

• Provides stable voltage regulation within a ±5% tolerance band across the operating range.
• Supports high-power dissipation up to 5 watts with defined derating characteristics above 75°C.
• Features low reverse leakage current and controlled dynamic impedance for precise circuit performance.
• Constructed with epoxy meeting UL 94 V-0 flammability ratings and available in halogen-free options.

Applications

• Voltage reference circuits requiring stable 16V regulation.
• Power supply protection against overvoltage transients.
• Clamping applications for transient voltage suppression.

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard -TP designation indicates tape and reel packaging. Adding the -HF suffix ensures the component is halogen-free. Confirm that the required quantity matches the manufacturer's standard packing sizes, such as 4,000 pieces per reel for the tape and reel option.

Selection Notes

Select this component for designs requiring a 16V Zener voltage with a 5-watt power rating. Ensure the application accounts for the thermal resistance from junction to ambient, which is 83°C/W. Verify that the peak surge currents do not exceed the specified limits for the intended pulse widths to prevent device degradation.

Part Context

This part belongs to the 1N5338B through 1N5388B series manufactured by Micro Commercial Components. The series covers Zener voltages ranging from 5.1V to 200V in the DO-15 package. The 1N5353B specifically targets the 16V segment of this high-power regulator lineup.

Replacement Considerations

Cross-reference with other manufacturers offering 16V 5W Zener diodes in the DO-15 package. Verify that substitute parts meet the same 5W power dissipation and ±5% voltage tolerance requirements. Check thermal resistance values to ensure equivalent heat management capabilities.

FAQ
