CMPZDA15V TR PBFREE

Overview

The CMPZDA15V TR PBFREE is a surface-mount dual common anode silicon Zener diode manufactured by Central Semiconductor Corp. It operates within a junction temperature range of -65°C to +175°C and provides a maximum power dissipation of 350 mW. The device features a nominal Zener voltage of 15 V, with a minimum of 13.8 V and a maximum of 15.6 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 30 Ω at the test current and 200 Ω at a knee current of 1.0 mA. Reverse leakage current is limited to 0.05 μA at a reverse voltage of 10 V, while the maximum Zener current reaches 10.5 mA.

Feature Summary

• Dual configuration with a common anode connection for simplified circuit design
• High-quality silicon construction suitable for industrial and commercial applications
• Surface-mount SOT-23 package optimized for automated assembly processes

Applications

• Voltage regulation in industrial control systems
• Signal clamping in commercial electronic equipment
• Reference voltage generation in computer hardware

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The PBFREE designation indicates lead-free compliance, which may differ from standard tin/lead variants. Confirm that the reel packaging matches the required quantity increments for production lines. Ensure storage conditions align with the specified thermal limits to maintain component integrity prior to installation.

Selection Notes

Select this component when a dual Zener arrangement with a shared anode is required for space-constrained designs. Evaluate the 350 mW power dissipation capability against the expected thermal load in the target application. Consider the SOT-23 footprint compatibility with existing PCB layouts. Verify that the 15 V nominal voltage meets the precise regulation requirements of the circuit design.

Part Context

This part belongs to the CMPZDA series of dual common anode silicon Zener diodes offered by Central Semiconductor. The series spans voltages from 2.4 V to 47 V, providing a standardized solution for various reference and regulation needs. All devices in this family share the same SOT-23 mechanical outline and thermal characteristics, ensuring consistency across different voltage selections.

Replacement Considerations

Direct substitutes must match the dual common anode topology, SOT-23 package, and 350 mW power rating. Verify that alternative components offer comparable Zener impedance and leakage current specifications at 15 V. Ensure the replacement supports the required operating temperature range of -65°C to +175°C.
