CMSZDA30V TR PBFREE

Overview

The CMSZDA30V TR PBFREE is a dual Zener diode manufactured by Central Semiconductor Corp. It features a common anode configuration with two silicon elements housed in a small outline plastic/epoxy package (R-PDSO-G3). The device operates within a temperature range of -65 °C to 150 °C and has a maximum power dissipation of 0.35 W. Key electrical parameters include a nominal Zener voltage of 30 V with a 5% tolerance, a maximum dynamic impedance of 80 Ω, and a knee impedance of 300 Ω. The component is unidirectional and utilizes three terminals.

Feature Summary

• Dual-element structure integrated into a single compact surface-mount package for space-constrained designs.
• Common anode configuration simplifies circuit layout for specific clamping or reference applications.
• High-temperature capability supports operation in demanding thermal environments up to 150 °C.

Applications

• Voltage reference circuits requiring dual stable potentials from a single common node.
• Signal conditioning stages utilizing the low dynamic impedance characteristics.
• Protection networks in consumer electronics where compact dual-diode solutions are preferred.

Procurement Notes

Verify compliance status carefully as the source data indicates the component is not RoHS compliant and carries an EAR99 classification. Confirm the specific suffix requirements for tape-and-reel packaging against current manufacturer documentation to ensure correct handling and storage conditions during assembly.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a small outline package. Ensure the 0.35 W power dissipation limit and 30 V breakdown voltage align with the target circuit design. Consider the non-RoHS status if environmental regulations apply to the final product.

Part Context

This part belongs to Central Semiconductor's discrete diode portfolio, specifically within the Zener diode category. It represents a dual-element variant designed for applications needing multiple voltage references or clamping functions in a minimal footprint, distinct from their transient voltage suppression series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers must consult official cross-reference guides or contact the manufacturer directly for verified equivalent components that match the electrical and mechanical specifications.
