CMPSH-3CG TR PBFREE is listed in the Diode Arrays range at ChipApex. The manufacturer field lists Central Semiconductor Corp. Its product description is DIODE ARR SCHOTT 30V 100MA SOT23. Review the specifications below when checking this part for your BOM.
The CMPSH-3CG TR PBFREE is a dual, common cathode Silicon Schottky diode designed for surface mount applications. It features a peak repetitive reverse voltage of 30 V and a continuous forward current of 100 mA per diode. The device operates within a junction temperature range of -65°C to +150°C. Key electrical characteristics include a maximum forward voltage of 1.00 V at 100 mA and a typical reverse leakage current of 500 nA at 25 V. The package is SOT-23 with a thermal resistance of 357 °C/W.
Verify the specific ordering suffix when purchasing. The 'PBFREE' suffix indicates lead-free plating, while 'TIN/LEAD' denotes tin/lead plating options. Confirm the manufacturer part number matches the required plating specification to ensure compliance with assembly processes and regulatory requirements.
Select this component for designs requiring low forward voltage and high-speed switching in a small footprint. Ensure the circuit's reverse voltage does not exceed 30 V and the average forward current remains within the 100 mA limit. Consider the thermal resistance of 357 °C/W for heat dissipation planning in enclosed environments.
This device belongs to the Central Semiconductor CMPSH-3 series of dual Schottky diodes. The series offers common cathode configurations in surface mount packages. The CMPSH-3CG variant specifically utilizes lead-free plating, distinguishing it from tin/lead versions like the CMPSH-3C TIN/LEAD.
Public confirmed substitute part numbers are not provided in the source documentation. Verify pinout compatibility and electrical ratings before considering alternative manufacturers.
The marking code for the CMPSH-3CG is DB2G.
The typical reverse recovery time is 5.0 ns under test conditions of IF=IR=10mA, Irr=1.0mA, and RL=100Ω.
The device is a dual, common cathode configuration where Pin 3 serves as the common cathode for both Anode D1 (Pin 2) and Anode D2 (Pin 1).
