CMSZDA6V2 TR PBFREE

Overview

The CMSZDA6V2 TR PBFREE is a dual unidirectional Zener diode array manufactured by Central Semiconductor Corp. It features a common anode configuration with two independent elements housed in a compact SOT-323 (SC-70) surface-mount package. The device provides a nominal Zener voltage of 6.2 V with a tolerance of ±5% and a maximum power dissipation of 275 mW. Key electrical characteristics include a maximum reverse leakage current of 3 µA, a Zener impedance of 10 Ohms, and a test current of 5 mA. The component operates within a temperature range of -65 °C to +150 °C and is supplied in reel packaging.

Feature Summary

• Dual element structure integrated into a single three-terminal surface-mount package for space-efficient circuit design.
• Common anode configuration simplifies biasing requirements for dual-channel voltage regulation or clamping applications.
• Low leakage current specification ensures minimal power loss and high isolation when the device is in the non-conducting state.

Applications

• Voltage reference generation in low-power analog signal processing circuits.
• Electrostatic discharge (ESD) protection for sensitive data lines requiring bidirectional clamping via common anode topology.
• Over-voltage protection in portable consumer electronics where board space is limited.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm lead-free status and tape-and-reel specifications. Ensure that the requested quantity aligns with the standard factory pack size to avoid partial reel handling issues. Cross-reference the Mouser part number 610-CMSZDA6V2TR-TL for accurate distributor identification and compliance documentation review prior to finalizing procurement orders.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in an SOT-323 footprint. The 6.2 V breakdown voltage makes it suitable for protecting 5 V logic interfaces. Consider the 275 mW power rating and thermal resistance during PCB layout planning. Verify that the 10 Ohm impedance meets the dynamic response requirements of the target application compared to higher-impedance alternatives.

Part Context

This part belongs to the CMSZDA series of dual Zener arrays from Central Semiconductor. These devices are designed to replace discrete dual-diode configurations, reducing component count and assembly complexity.
