1N5350B

Overview

The Diotec Semiconductor 1N5350B is a non-planar silicon Zener diode designed for voltage stabilization and regulation. It features a nominal Zener voltage of 13 V with a standard tolerance of ±5%. The device supports a maximum power dissipation of 5 W at an ambient temperature of 50°C, utilizing the DO-201 axial leaded package. Key electrical characteristics include a test current of 100 mA, a dynamic resistance of 2.5 Ω, and a reverse leakage current of 1 µA at 9.9 V. It operates within a junction temperature range of -50°C to +150°C.

Feature Summary

• High power dissipation capability up to 5 W
• Non-planar technology for robust performance
• Standardized E24 voltage grading for consistent tolerances

Applications

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

Procurement Notes

Verify compliance with specific environmental standards such as RoHS and REACH requirements before procurement. Confirm that the ordering suffix matches the required qualification grade, noting that standard versions are commercial/industrial grade while suffixes like -Q indicate AEC-Q101 compliance. Ensure the component meets the intended thermal management conditions specified in the datasheet.

Selection Notes

Select this component for applications requiring stable voltage reference or regulation at 13 V. Consider the 5 W power rating and thermal resistance when designing heat dissipation strategies. Verify that the operating environment stays within the specified temperature limits and that the package type suits the assembly process.

Part Context

This part belongs to the 1N5345B through 1N5388B series of Zener diodes from Diotec Semiconductor. The series offers a wide range of Zener voltages from 8.7 V to 200 V, all sharing similar mechanical and electrical characteristics including the DO-201 package and 5 W power rating. This allows for standardized design approaches across different voltage requirements.

Replacement Considerations

Check for equivalent parts from other manufacturers offering 13 V, 5 W Zener diodes in the DO-201 package. Verify that any substitute matches the dynamic resistance, leakage current, and power dissipation ratings to ensure circuit compatibility.
