CMSD2838 TR PBFREE

Diode Arrays Overview

The CMSD2838 TR PBFREE is a surface mount dual silicon switching diode manufactured by Central Semiconductor Corp. It utilizes an epitaxial planar process within an epoxy molded SUPERmini™ package (SOT-323). The device features a common cathode configuration with a peak repetitive reverse voltage of 75 V and an average forward current rating of 200 mA. Key electrical characteristics include a maximum reverse leakage current of 100 nA at 50 V, a typical reverse recovery time of 4.0 ns, and a junction temperature range from -65 to +150 °C.

Diode Arrays Feature Summary

• Ultra-high speed switching capability utilizing an epitaxial planar process
• Dual diode structure housed in a compact SUPERmini™ surface mount package
• Common cathode internal configuration for simplified circuit integration

Diode Arrays Applications

• High speed switching applications
• General purpose rectification circuits
• Surface mount assembly processes

Diode Arrays Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The PBFREE designation indicates lead-free compliance, while alternative suffixes may denote tin/lead plating. Confirm the tape and reel quantity matches the TR designation requirements for automated placement equipment. Ensure the SOT-323 package outline aligns with the target PCB footprint design constraints.

Diode Arrays Selection Notes

Select this component when a dual common cathode switching diode is required in a small surface mount form factor. The 75 V reverse voltage rating suits low-voltage signal processing tasks. The 4.0 ns reverse recovery time supports high-frequency operation. Verify that the 200 mA average forward current meets the load requirements and that the thermal resistance allows for adequate heat dissipation in the intended enclosure environment.

Diode Arrays Part Context

This part belongs to the CMSD2836/CMSD2838 family of ultra-high speed silicon switching diodes. The CMSD2838 variant specifically provides a common cathode arrangement, whereas the CMSD2836 offers a common anode configuration. Both share identical electrical ratings and physical packaging dimensions, differing only in internal pin connectivity and marking codes.
