1N5366B-TP

Overview

The 1N5366B-TP is a silicon Zener diode manufactured by Micro Commercial Components (MCC) in the DO-15 axial leaded package. It provides a nominal Zener voltage of 39V with a ±5% tolerance. The device supports a maximum DC power dissipation of 5W at a lead temperature of 75°C, with a derating factor of 67mW/°C above this threshold. Key electrical parameters include a maximum dynamic impedance of 14 Ohms and a maximum reverse leakage current of 0.5µA at a test voltage of 29.7V. The component operates within a junction temperature range of -55°C to +150°C for DC conditions.

Feature Summary

• Epoxy encapsulation meets UL 94 V-0 flammability rating
• Lead-free finish compliant with RoHS directives
• Halogen-free option available via specific ordering suffix

Applications

• Voltage regulation circuits
• Surge protection applications
• Reference voltage sources

Procurement Notes

Verify compliance requirements against project specifications. Confirm that the standard version meets environmental standards or if the halogen-free variant is required. Ensure sourcing from authorized distributors to guarantee genuine parts and full traceability. Check datasheet revisions for any updates to mechanical dimensions or thermal characteristics before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a 39V reference point with moderate power handling capabilities. The DO-15 package offers robust heat dissipation suitable for through-hole mounting. Consider the thermal resistance values when designing PCB layouts to ensure the junction temperature remains within safe operating limits under maximum load conditions.

Part Context

This part belongs to the 1N5338B through 1N5388B series of 5-watt Zener diodes produced by MCC. The series covers a wide voltage range from 5.1V to 200V. The 'B' suffix indicates a standard ±5% voltage tolerance, while the '-TP' suffix designates RoHS compliance. These devices are designed for general-purpose voltage regulation and protection tasks in industrial and commercial electronics.

Replacement Considerations

Equivalent parts within the same JEDEC registered series may be substituted if they match the 39V nominal voltage, 5W power rating, and DO-15 package dimensions. Verify that alternative manufacturers meet the same thermal and electrical specifications.
