• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for versatile integration

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection systems
• Reference voltage generation

Procurement Notes

Verify the specific suffix configuration against the datasheet to confirm tolerance and compliance status. Ensure the ordering code matches the required packaging option, such as tape and reel, if applicable. Confirm that the component meets the necessary environmental standards for the intended deployment environment before finalizing procurement.

Selection Notes

Select this component when a 150V Zener reference is required with ±5% tolerance. Consider the 5W power rating and thermal resistance characteristics for adequate heat sinking. Verify compatibility with the system's operating temperature range and ensure the axial lead format fits the mechanical design constraints.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. The e3 suffix indicates RoHS compliance, while the TR8 suffix typically denotes tape and reel packaging options available for this family.

Replacement Considerations

Equivalent parts include other 150V 5W Zener diodes from the same series or compatible manufacturers. Verify pinout, voltage tolerance, and power dissipation ratings match the original design requirements before substitution.
