- Features flexible axial-lead mounting terminals for versatile integration
- Withstands high surge stresses and exhibits minimal voltage change versus current
- Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack
Applications
- Voltage regulation in electronic circuits
- High DC current applications with adequate heat sinking
- Surge stress protection scenarios
Procurement Notes
Verify the component matches the specific JEDEC registered series requirements. Confirm that the RoHS compliant e3 designation aligns with environmental standards. Ensure the TR8 tape and reel packaging meets storage and handling specifications. Check for any prefix identifiers if military equivalent screening levels are required for the application.
Selection Notes
Select this component when a 190 V Zener voltage with ±5% tolerance is necessary. Consider the 5-watt power rating and thermal resistance characteristics for heat management. Verify compatibility with the T-18 axial leaded package dimensions. Evaluate the need for RoHS compliance and tape and reel delivery format.
Part Context
This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 to 200 volts. The B suffix indicates standard voltage tolerances, while the e3 suffix denotes RoHS compliance. These devices are designed for robust performance in various industrial and commercial applications.
Replacement Considerations
Equivalent parts within the 1N5333B-5388B series may be considered if voltage and power ratings match. Verify package compatibility and electrical parameters before substitution.
