Overview
The Diotec Semiconductor 1N5358B is a non-planar silicon Zener diode designed for voltage stabilization and regulation. 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 22 V, tested at a current of 50 mA, with a dynamic resistance of 3.5 Ω. The device operates within a junction temperature range of -50°C to +150°C and supports a non-repetitive peak surge current of up to 80 W for pulses under 8.3 ms.
Feature Summary
- High power dissipation capability of 5 W in a standard through-hole package
- Glass passivated junction providing reliable performance across commercial and industrial temperature ranges
- Compliant with RoHS directives and REACH regulations
Applications
- Voltage stabilization circuits
- Linear voltage regulators
- Overvoltage protection applications
Procurement Notes
Verify the specific manufacturer part number against official Diotec Semiconductor documentation to ensure compliance with the stated electrical characteristics. Confirm that the component matches the DO-201 mechanical dimensions and lead configuration required by your design. Ensure all ordering suffixes are validated against the manufacturer's latest datasheet to confirm any additional automotive or specialized qualifications.
Selection Notes
Select this component when a stable 22 V reference point is required in high-power environments. The 5 W rating allows for significant thermal handling without excessive heatsinking if leads are maintained at ambient temperature. Verify that the operating current remains within the specified test conditions to maintain the ±5% voltage tolerance accuracy.
Part Context
This component belongs to the 1N5345B through 1N5388B series of non-planar Zener diodes manufactured by Diotec Semiconductor. The series covers a wide voltage range from 8.7 V to 200 V, all sharing the same 5 W power dissipation rating and DO-201 package style. This family is standardized for commercial and industrial grade reliability.
Replacement Considerations
Cross-reference with other manufacturers' 1N5358 equivalents. Verify that substitute parts meet the identical 22 V nominal voltage, 5 W power rating, and DO-201 package constraints.
