Overview
The Diotec Semiconductor 1N5351B is a non-planar Zener diode designed for through-hole mounting in the DO-201 axial package. It provides a nominal Zener voltage of 14 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 100 mA, a dynamic resistance of 2.5 Ohms, and a maximum reverse leakage current of 1 µA at 11.5 V.
Feature Summary
- High power dissipation capability up to 5 W
- Non-planar technology construction
- Compliant with RoHS standards
Applications
- Voltage stabilization circuits
- Regulator applications
- Overvoltage protection
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm compliance status regarding RoHS directives and REACH regulations before integration. Ensure ordering suffixes match required automotive qualifications if applicable. Validate package dimensions and lead configurations against PCB layout requirements.
Selection Notes
Select this component for designs requiring robust voltage regulation with high thermal stability. The DO-201 package accommodates significant power handling needs compared to smaller surface-mount alternatives. Verify that the 14 V breakdown voltage aligns precisely with circuit reference requirements. Consider the 2.5 Ohm dynamic resistance for ripple rejection performance in linear regulator topologies.
Part Context
This part belongs to the 1N5345B through 1N5388B series manufactured by Diotec Semiconductor. The series utilizes non-planar technology and covers a wide voltage range from 8.7 V to 200 V. All devices share the same DO-201 mechanical outline and 5 W power rating, differing primarily in their specific Zener voltage ratings and associated test currents.
Replacement Considerations
Cross-reference with other manufacturers' 1N5351 equivalents ensuring identical 14 V Zener voltage, 5 W power rating, and DO-201 package compatibility. Verify matching dynamic resistance and leakage current specifications to maintain circuit performance integrity.
