Overview
The CMSZDA47V TR TIN/LEAD is a dual Zener diode array manufactured by Central Semiconductor Corp. It features a common anode configuration housed in an SOT-323 surface-mount package. The nominal Zener voltage is 47 V with a tolerance of ±5%. Maximum power dissipation is rated at 275 mW, and the maximum dynamic impedance is 100 Ohms. The device operates within a temperature range of -65 °C to +150 °C.
Feature Summary
- Dual Zener diodes integrated into a single compact surface-mount package
- Common anode configuration for simplified circuit design
- High thermal stability suitable for wide operating temperature ranges
Applications
- Voltage reference circuits requiring dual polarity or split supplies
- Over-voltage protection stages in industrial equipment
- Signal conditioning modules in commercial electronics
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status as leaded variants may differ from lead-free equivalents. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent package damage during soldering processes.
Selection Notes
Select this component when a dual Zener solution with common anode topology is required in an SOT-323 footprint. Evaluate the 275 mW power rating against peak current demands. Consider the 100 Ohm dynamic impedance for noise-sensitive applications where lower impedance alternatives might be necessary.
Part Context
This part belongs to the CMSZDA series of dual silicon Zener diodes from Central Semiconductor. The series offers various voltage options within the same SOT-323 package, allowing for consistent board layout across different voltage reference designs while maintaining uniform thermal and mechanical characteristics.
Replacement Considerations
Cross-reference with other SOT-323 dual Zener arrays featuring common anode configurations. Verify that substitute parts match the 47 V nominal voltage, ±5% tolerance, and 275 mW power dissipation limits to ensure electrical compatibility.
