Overview
The Diotec Semiconductor 1N5354B is a non-planar silicon Zener diode designed for voltage regulation and stabilization. It features a nominal Zener voltage of 17 V with a standard tolerance of ±5%. The device operates within a junction temperature range of -50°C to +150°C and dissipates up to 5 W at 50°C ambient temperature. Packaged in the DO-201 axial leaded format, it provides high peak reverse power dissipation capability.
Feature Summary
- High power dissipation capability suitable for demanding thermal environments
- Non-planar technology ensuring stable voltage regulation across a wide current range
- Compliant with RoHS directives and REACH regulations
Applications
- Voltage stabilization circuits
- Power supply regulators
- Overvoltage protection (uni-directional)
Procurement Notes
Verify that the specific order matches the 1N5354B designation to ensure the correct 17 V rating. Confirm package type is DO-201 for through-hole mounting. Check for suffixes like -Q or -AQ if automotive AEC-Q101 compliance is required, as these denote different qualification levels than the standard commercial grade.
Selection Notes
Select this component when a robust 5 W Zener diode is needed for industrial or commercial voltage reference applications. Ensure the circuit design accounts for the 2.5 Ω dynamic resistance at the test current. Verify that the operating junction temperature remains within the specified limits during continuous operation.
Part Context
This part belongs to the 1N5345B through 1N5388B series from Diotec Semiconductor. The series covers a broad voltage range from 8.7 V to 200 V, all sharing the same 5 W power dissipation rating and DO-201 mechanical footprint. This allows for consistent board layout across various voltage requirements.
Replacement Considerations
Cross-reference with other manufacturers' 1N5354B equivalents. Verify that any substitute maintains the 17 V nominal voltage, 5 W power rating, and DO-201 package dimensions to ensure physical and electrical compatibility.
