Overview
The CMPZDA30V TR TIN/LEAD is a dual silicon Zener diode in a surface-mount SOT-23 package, configured as common anode. It provides a nominal Zener voltage of 30V with a tolerance range of 28.0V to 32.0V at a test current of 2.0mA. The device supports a maximum power dissipation of 350mW and operates within a junction temperature range of -65°C to +175°C. Key electrical parameters include a maximum Zener impedance of 80Ω at the test current and 300Ω at knee current, a maximum reverse leakage current of 0.05μA at 21.0V, and a maximum Zener current of 23.1mA.
Feature Summary
- Dual Zener diodes integrated into a single common anode configuration for space-efficient circuit design.
- Silicon construction optimized for stable voltage regulation across industrial and commercial applications.
- Surface-mount SOT-23 packaging facilitates automated assembly and compact board layouts.
Applications
- Industrial control systems requiring precise voltage reference points.
- Commercial equipment utilizing low-power voltage regulation circuits.
- Computer hardware interfaces needing stable DC voltage levels.
Procurement Notes
Verify the specific ordering suffix when purchasing. The 'TIN/LEAD' designation indicates non-lead-free plating options, which may differ from standard RoHS-compliant variants. Confirm the 'TR' suffix corresponds to reel packaging requirements for your manufacturing line. Ensure compatibility with local environmental regulations regarding lead content before finalizing procurement orders.
Selection Notes
Select this component when a dual common-anode Zener configuration is required in a small SOT-23 footprint. The 30V nominal rating suits applications needing moderate voltage clamping or reference. Consider the 350mW power dissipation limit and thermal resistance of 429°C/W for heat management. Verify that the 80Ω dynamic impedance meets the noise and stability requirements of the target circuit.
Part Context
This part belongs to the CMPZDA series, which covers Zener voltages from 2.4V to 47V. All devices in this series share the same dual common-anode architecture and SOT-23 mechanical outline. The CMPZDA30V represents the mid-range voltage option within this broad family of surface-mount regulators.
Replacement Considerations
Direct replacements must match the dual common-anode topology and SOT-23-3 package. Verify equivalent Zener voltage (28V–32V), power dissipation (≥350mW), and impedance characteristics. Cross-reference marking codes if visual identification is necessary for assembly verification.
