CMPZDA22V TR PBFREE

Overview

The CMPZDA22V TR PBFREE is a dual Zener diode array manufactured by Central Semiconductor Corp, housed in an SOT-23 surface-mount package. It features a common anode configuration with a nominal voltage of 22 V and a tolerance of ±5%. The device supports a maximum power dissipation of 350 mW and exhibits a dynamic impedance of 80 Ohms. Operating temperatures range from -65°C to 175°C (TJ).

Feature Summary

• Dual Zener diode array with common anode topology.
• Surface-mount SOT-23 package for compact integration.
• High junction temperature rating up to 175°C.

Applications

• Voltage reference circuits requiring dual regulation.
• Transient voltage suppression in signal lines.
• Clamping applications in low-power electronics.

Procurement Notes

Verify the specific suffix 'TR PBFREE' ensures lead-free plating and tape-and-reel packaging. Confirm RoHS compliance status directly with the manufacturer or authorized distributor prior to ordering. Ensure the component matches the required SOT-23 footprint and electrical specifications for the target design.

Selection Notes

Select this component when a dual Zener solution with common anode connectivity is required in a small form factor. The 22 V nominal voltage and 350 mW power rating suit low-voltage protection tasks. Verify that the 80 Ohm dynamic impedance meets the noise and regulation requirements of the application circuit.
