Overview
The Central Semiconductor CMSZDA10V TR PBFREE is a surface-mount dual common anode silicon zener diode. It provides a nominal zener voltage of 10 V with a tolerance range of 9.4 V to 10.6 V at a test current of 5.0 mA. The device dissipates up to 275 mW and operates within a junction temperature range of -65 °C to +150 °C. Electrical specifications include a maximum zener impedance of 20 Ω at the test current, a reverse leakage current of 0.2 µA at 7.0 V, and a maximum zener current of 8.0 mA. The component utilizes a SOT-323 package.
Feature Summary
- Dual configuration with a common anode connection for efficient circuit layout
- High-reliability silicon construction designed for industrial and commercial applications
- Surface-mount design in a compact SOT-323 case size
Applications
- Industrial equipment voltage regulation
- Commercial electronic systems
- Computer application circuits
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The PBFREE designation indicates lead-free compliance. Confirm availability through authorized distributors as manufacturing schedules may vary. Ensure the requested quantity aligns with standard reel packaging requirements specified by the supplier.
Selection Notes
Select this component when a dual zener arrangement with a shared anode is required. Verify that the 275 mW power dissipation rating meets the thermal requirements of the target application. Check that the 10 V nominal voltage falls within the necessary regulation window for the specific circuit design constraints.
Part Context
This part belongs to the CMSZDA series, which covers zener voltages from 2.4 V to 47 V. All devices in this family share identical physical dimensions and pin configurations while varying in electrical characteristics. The series is specifically engineered for surface-mount technology implementations requiring dual regulator functions.
Replacement Considerations
Direct replacements must match the SOT-323 footprint and dual common anode topology. Verify that substitute components meet or exceed the 275 mW power dissipation and -65 °C to +150 °C operating temperature range. Cross-reference specific zener voltage tolerances to ensure circuit compatibility.
