CMSZDA7V5 TR PBFREE

Overview

The CMSZDA7V5 TR PBFREE is a Zener diode array manufactured by Central Semiconductor Corp, housed in an SOT-323 surface-mount package. It features a nominal Zener voltage of 7.5 V with a ±5% tolerance and a maximum power dissipation of 275 mW. The device consists of one pair of common-anode Zener diodes. Key electrical parameters include a reverse leakage current of 1 µA at 2 V and a forward voltage of 900 mV at 10 mA. The operating temperature range spans from -65°C to +150°C.

Feature Summary

• Dual Zener configuration within a compact SOT-323 footprint
• Common-anode topology for simplified circuit integration
• High thermal stability across extended industrial temperature ranges

Applications

• Voltage reference circuits requiring dual independent references
• Over-voltage protection for sensitive signal lines
• Clamping applications in portable electronic devices

Procurement Notes

Verify the specific suffix and tape-and-reel quantity against the manufacturer's latest datasheet before ordering. Confirm RoHS compliance status and ensure the SOT-323 package dimensions match your PCB layout constraints. Cross-reference the part number with authorized distributors to confirm current production status and availability.

Selection Notes

Select this component when a dual Zener solution is required in a minimal surface-mount package. Ensure the 275 mW power rating suffices for your application's thermal environment. Verify that the 7.5 V breakdown voltage aligns with your circuit's clamping or reference requirements. Consider the common-anode configuration for proper biasing in your design.

Part Context

This part belongs to the CMSZDA series of Zener arrays from Central Semiconductor. These components are designed for space-constrained applications where multiple voltage references or protection elements are needed. The SOT-323 package offers a small outline suitable for high-density PCB assembly.

Replacement Considerations

Check for direct pin-compatible alternatives from other manufacturers offering similar Zener voltages and power ratings in the SOT-323 package. Verify electrical characteristics such as leakage current and dynamic impedance to ensure functional equivalence.
