Overview
The CMSZDA7V5 TR TIN/LEAD is a dual common anode Zener diode array manufactured by Central Semiconductor Corp. It features a nominal Zener voltage of 7.5 V with a tolerance of ±5%. The device operates in the SOT-323 (SC-70) surface-mount package and provides a maximum power dissipation of 275 mW. Key electrical characteristics include a reverse leakage current of 1 µA at 2 V, a forward voltage of 900 mV at 10 mA, and a Zener impedance of 40 Ohms. It supports a wide operating temperature range from -65°C to +150°C.
Feature Summary
- Dual common anode configuration for efficient space-saving circuit design
- High thermal stability with extended operating temperature range up to 150°C
- Low leakage current ensuring minimal power loss in standby states
Applications
- Voltage reference circuits requiring stable dual supply rails
- Clamping applications for transient voltage suppression
- Signal conditioning in portable electronic devices
Procurement Notes
Verify the specific ordering suffix to confirm the tin/lead termination plating option, as lead-free variants may be available under different part numbers. Confirm the reel quantity matches production requirements before finalizing orders. Ensure compatibility with standard reflow soldering profiles for SOT-323 packages during assembly planning.
Selection Notes
Select this component when a dual Zener configuration is required in a compact SOT-323 footprint. Compare the 7.5 V breakdown voltage against circuit requirements to ensure proper clamping levels. Consider the 275 mW power rating for thermal management in dense PCB layouts.
Part Context
This part belongs to the CMSZDA series of dual Zener diode arrays from Central Semiconductor. These components are designed for general-purpose voltage regulation and protection in consumer electronics. The series offers various voltage options within the same standardized package format.
Replacement Considerations
Check for CMSZDA7V5 TR PBFREE or other suffix variations if lead-free compliance is mandatory. Verify pinout compatibility with existing designs when substituting with similar dual Zener arrays from other manufacturers.
