Single Zener Diodes Procurement Notes

Verify component authenticity and datasheet alignment before procurement. Confirm the specific suffix matches the required tolerance and packaging format. Check for end-of-life status or alternative sourcing options due to potential discontinuation. Ensure compliance with relevant environmental standards such as RoHS requirements for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a 150 V Zener voltage with 3 W power handling is required in an axial package. Consider the 550 Ohm impedance limit for dynamic regulation needs. Evaluate the wide operating temperature range for harsh environments. Compare against lower power alternatives if space constraints allow for smaller packages.

Single Zener Diodes Part Context

This part belongs to the 3EZ series of high-power Zener diodes manufactured by Microsemi. It shares the DO-204AL package form factor with other variants in the lineup but differs in voltage rating and power dissipation capabilities. The series is designed for applications requiring robust voltage clamping and regulation in industrial and commercial electronics.
