1N5345B

Single Zener Diodes Overview

The Diotec Semiconductor 1N5345B is a non-planar silicon Zener diode housed in a DO-201 axial leaded package. It provides a nominal Zener voltage of 8.7 V with a standard tolerance of ±5%. The device supports a maximum power dissipation of 5 W at an ambient temperature of 50°C and operates within a junction temperature range of -50°C to +150°C. Key electrical characteristics include a test current of 150 mA, a dynamic resistance of 2 Ω, and a reverse leakage current of 10 µA at 200 V. The component is compliant with RoHS standards (excluding exemption 7A-I) and REACH regulations.

Single Zener Diodes Feature Summary

• Non-planar technology ensuring stable voltage regulation characteristics
• Compliant with RoHS directives and REACH chemical regulations

Single Zener Diodes Applications

• Voltage stabilization circuits
• Linear voltage regulators
• Overvoltage protection interfaces

Single Zener Diodes Procurement Notes

Verify the specific suffix designation when ordering, as variants such as -Q denote AEC-Q101 compliance while standard versions lack this automotive qualification. Confirm that the required packaging format matches the available ammo pack configuration containing 1700 units per reel. Ensure design parameters account for the specified thermal resistance values relative to lead length and ambient conditions during operation.

Single Zener Diodes Selection Notes

Select the 1N5345B for applications requiring precise 8.7 V reference levels with high power handling capabilities. Consider the ±5% tolerance band for circuit accuracy requirements. Evaluate the thermal management strategy based on the 25 K/W junction-to-ambient resistance value. Verify compatibility with through-hole assembly processes given the DO-201 mechanical form factor.

Single Zener Diodes Part Context

This component belongs to the Diotec 1N5345B through 1N5388B series of glass-passivated junction silicon Zener diodes. The series utilizes diffused Zener technology to achieve voltage ratings from 8.7 V up to 200 V. All devices share the same DO-201 axial package and 5 W power rating profile, differing primarily in their specific breakdown voltage thresholds and associated test currents.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5345B equivalents or 1N53xxB series parts sharing identical 8.7 V specifications and DO-201 packages. Verify matching dynamic resistance and thermal characteristics before substitution.
