Overview
The Diotec Semiconductor 1N5386B is a non-planar silicon Zener diode housed in the DO-201 axial leaded package. It provides a nominal Zener voltage of 180 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 can withstand non-repetitive peak pulse power of 80 W for durations under 8.3 ms. It operates within a junction temperature range of -50°C to +150°C.
Feature Summary
- High power dissipation capability up to 5 W
- Zener voltage ratings extending up to 200 V
- Compliant with RoHS directives (excluding exemption 7A-I)
- REACH compliant and free of conflict minerals
Applications
- Voltage stabilization circuits
- Voltage regulators
- Overvoltage protection applications
Procurement Notes
Verify that the specific part number matches the required electrical characteristics, particularly the 180 V Zener voltage and 5 W power rating. Confirm compliance requirements such as RoHS status and AEC-Q101 qualification if applicable. Ensure the DO-201 package dimensions align with the target PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a robust through-hole Zener diode is needed for high-voltage regulation tasks. The 180 V rating suits applications requiring stable reference voltages or clamping in industrial environments. Consider the thermal resistance values and derating curves for accurate power handling calculations under varying ambient temperatures.
Part Context
This component belongs to the 1N5345B through 1N5388B series of glass passivated Zener diodes manufactured by Diotec Semiconductor. The series utilizes non-planar technology and offers a wide range of standardized Zener voltages from 8.7 V to 200 V. All variants share the same DO-201 plastic housing and mechanical specifications, differing primarily in their breakdown voltage and associated test currents.
Replacement Considerations
Cross-reference with other manufacturers' 1N5386 equivalents. Verify that substitute parts meet the identical 180 V Zener voltage, ±5% tolerance, and 5 W power dissipation limits. Ensure the replacement maintains the DO-201 axial package form factor for direct board compatibility.
