1N5356B

Overview

The Diotec Semiconductor 1N5356B is a non-planar silicon Zener diode designed for voltage regulation and stabilization. It features a nominal Zener voltage of 19 V with a standard tolerance of ±5%. The device supports a maximum power dissipation of 5 W at an ambient temperature of 50°C, with a dynamic resistance of 3 Ω measured at a test current of 65 mA. It operates within a junction temperature range of -50°C to +150°C and utilizes a DO-201 axial leaded package.

Feature Summary

• High power dissipation capability up to 5 W
• Non-planar technology for robust performance
• Compliant with RoHS directives

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance status. Standard commercial grades are available without automotive qualification. Confirm that the component meets REACH regulations and conflict mineral requirements as specified in the manufacturer's datasheet before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring a 19 V reference or clamp with moderate power handling. Ensure thermal management allows for operation within the specified 5 W limit at 50°C ambient conditions. Verify that the required surge current withstand capability aligns with the circuit's transient energy profile.

Part Context

This part belongs to the 1N5345B through 1N5388B series of Zener diodes. The series covers a wide voltage range from 8.7 V to 200 V, all sharing the same 5 W power rating and DO-201 package form factor. This family provides standardized solutions for various voltage regulation needs in commercial and industrial environments.

Replacement Considerations

Cross-reference with other manufacturers' 1N5356B equivalents. Verify that any substitute matches the 19 V nominal voltage, 5 W power rating, and DO-201 package dimensions.
