1N5366B

Overview

The Diotec Semiconductor 1N5366B is a non-planar silicon Zener diode designed for voltage stabilization and regulation applications. It features a DO-201 axial leaded package with a maximum power dissipation of 5 W at 50°C ambient temperature. The device provides a nominal Zener voltage of 39 V with a standard tolerance of ±5%. Key electrical characteristics include a test current of 30 mA, a dynamic resistance of 14 Ω, and a reverse leakage current of less than 1 µA at 29.7 V. It operates within a junction temperature range of -50°C to +150°C.

Feature Summary

• High power dissipation capability up to 5 W in a rugged DO-201 package
• Non-planar technology ensuring high reliability and robust performance
• Compliant with RoHS directives and REACH regulations

Applications

• Voltage stabilization circuits
• DC voltage regulators
• Overvoltage protection (uni-directional)

Procurement Notes

Verify the specific ordering suffix when purchasing. Standard versions are commercial/industrial grade. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes qualification status. Confirm that the required automotive or industrial grade matches the project specifications before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a 39 V reference point with moderate current handling. Ensure the thermal design accounts for the 5 W dissipation limit at elevated ambient temperatures. Verify that the ±5% voltage tolerance meets the circuit requirements. Consider the DO-201 package dimensions for PCB layout constraints.

Part Context

This part belongs to the 1N5345B through 1N5388B series of 5 W Zener diodes manufactured by Diotec Semiconductor. The series covers a wide voltage range from 8.7 V to 200 V using non-planar technology. These components are standardized for general-purpose voltage regulation tasks in commercial and industrial electronics.

Replacement Considerations

Cross-reference with other manufacturers' 1N5366 equivalents. Verify that substitute parts match the 39 V Zener voltage, 5 W power rating, and DO-201 package form factor. Check dynamic resistance and leakage current specifications to ensure functional parity.
