1N5367B

Overview

The Diotec Semiconductor 1N5367B is a non-planar silicon Zener diode designed for voltage regulation and stabilization. It features a DO-201 axial leaded package with a maximum power dissipation of 5 W at 50°C ambient temperature. The nominal Zener voltage is 43 V with a standard tolerance of ±5%. Key electrical characteristics include a test current of 30 mA, a dynamic resistance of 20 Ω, and a reverse leakage current of 0.5 μA at 190 V. The device operates within a junction temperature range of -50°C to +150°C.

Feature Summary

• High power dissipation capability up to 5 W in the DO-201 through-hole package
• Non-planar technology providing robust voltage regulation performance
• Compliant with RoHS directives and REACH regulations

Applications

• Voltage stabilization circuits
• Regulator applications
• Overvoltage protection (uni-directional)

Procurement Notes

Verify the specific manufacturer lot and datasheet revision before integration, as specifications may vary between production batches. Confirm compliance with RoHS and REACH requirements relevant to your region. Ensure thermal management design accounts for the 5 W dissipation limit at 50°C ambient temperature. Check for AEC-Q101 automotive qualification if required by the application environment.

Selection Notes

Select this component when a 43 V reference or clamp is needed with high power handling. The DO-201 package suits through-hole designs requiring robust mechanical mounting. Consider the 20 Ω dynamic resistance for load regulation accuracy. Verify that the 5 W rating aligns with the expected duty cycle and ambient thermal conditions of the final assembly.

Part Context

This part belongs to the Diotec 1N5345B–1N5388B series of non-planar 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 form factor. These components are standardized commercial/industrial grade devices intended for general-purpose electronic circuits.

Replacement Considerations

Cross-reference with other manufacturers' 1N5367B equivalents such as those from Microsemi or Panasonic. Ensure substitute parts match the 43 V nominal voltage, 5 W power rating, and DO-201 package dimensions. Verify that dynamic resistance and leakage current specifications meet the circuit requirements.
