CMSZDA43V TR PBFREE

Overview

The CMSZDA43V TR PBFREE is a dual unidirectional Zener diode array manufactured by Central Semiconductor Corp. It utilizes silicon technology and is housed in an SOT-323 surface-mount package. The device features a nominal breakdown voltage of 12 V with a tolerance of ±5%. Each internal diode supports a maximum power dissipation of 0.25 W (250 mW). The component operates within a junction temperature range from -65 °C to +150 °C. It is supplied in a tape-and-reel configuration for automated assembly processes.

Feature Summary

• Dual unidirectional configuration providing two independent Zener channels in a single compact package
• High thermal stability capable of operating at junction temperatures up to 150 °C
• Precision voltage regulation with tight ±5% breakdown voltage tolerance

Applications

• Voltage reference circuits requiring dual regulated rails
• Transient voltage suppression in low-power signal lines
• Clamping applications in portable electronic devices

Procurement Notes

Verify the specific manufacturer part number against official Central Semiconductor documentation to confirm the exact electrical characteristics and packaging details. Ensure that the ordering suffix corresponds to the required reel quantity and lead-free compliance status before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel Zener solution is required in a minimal footprint. The SOT-323 package is suitable for space-constrained designs. Confirm that the 12 V breakdown voltage aligns with the circuit's clamping or reference requirements and that the 250 mW power rating is sufficient for the expected current load.

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 tasks where board space is limited. The series offers various voltage options within the same physical package format to simplify inventory management.

Replacement Considerations

Consult official substitution guides for equivalent dual Zener arrays in SOT-323 packages. Verify that any alternative component matches the 12 V breakdown voltage, ±5% tolerance, and 250 mW power dissipation specifications to ensure functional compatibility.
