CMPD2838 TR PBFREE

Diode Arrays Overview

The CMPD2838 TR PBFREE is a surface mount dual silicon switching diode manufactured by Central Semiconductor Corp. It features a common cathode configuration within an SOT-23 package. Key electrical parameters include a peak repetitive reverse voltage of 75 V and an average forward current rating of 200 mA. The device exhibits a maximum reverse leakage current of 100 nA at 50 V, with a typical reverse breakdown voltage of 75 V. Forward voltage drop ranges from 1.0 V to 1.2 V depending on current levels up to 100 mA. Junction capacitance is specified between 1.5 pF and 4.0 pF at 1.0 MHz. Reverse recovery time is typically 4.0 ns. Operating and storage junction temperatures range from -65°C to +150°C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm lead plating composition. The 'TR' suffix indicates tape and reel packaging, while 'PBFREE' denotes lead-free termination. Confirm the exact reel size (7-inch or 13-inch) required for your automated assembly equipment, as quantities per box vary significantly between these configurations.

Diode Arrays Selection Notes

Select this component when a dual common cathode switching diode is required in an SOT-23 footprint. Ensure the circuit design accommodates the 75 V reverse voltage limit and 200 mA average forward current constraints. Verify that the thermal resistance of 357 °C/W aligns with the system's heat dissipation capabilities under continuous operation conditions.

Diode Arrays Part Context

This part belongs to the CMPD2836/CMPD2838 series of ultra-high speed switching diodes. The CMPD2838 variant specifically utilizes a common cathode arrangement, whereas the CMPD2836 uses a common anode configuration. Both share identical physical dimensions and electrical ratings, differing only in internal pin connectivity and marking codes.

Diode Arrays Replacement Considerations

Direct functional substitutes include the CMPD2836 if a common anode configuration is acceptable. Other dual switching diodes in SOT-23 packages may be considered if their voltage and current ratings meet or exceed the 75 V and 200 mA specifications respectively.
