The CMPD2004S TR PBFREE is a high-voltage silicon switching diode manufactured by Central Semiconductor Corp using an epitaxial planar process. It features a dual in-series configuration within a surface-mount SOT-23 package. Key electrical parameters include a continuous reverse voltage of 240 V, a peak repetitive reverse voltage of 300 V, and an average forward current of 200 mA. The device supports a maximum power dissipation of 350 mW and operates across a junction temperature range of -65°C to +150°C.
Verify the exact part number against official datasheets before procurement. Confirm that the 'TR' suffix indicates tape and reel packaging and 'PBFREE' denotes lead-free plating as specified by the manufacturer. Ensure compatibility with standard SOT-23 footprint requirements on the target printed circuit board layout.
Select this component when a dual in-series diode arrangement is required within a small surface-mount form factor. Consider the 240 V continuous reverse voltage rating and 200 mA average forward current limits during design. Evaluate thermal resistance and power dissipation constraints relative to the expected operating environment and ambient temperatures.
This component belongs to the CMPD2003/CMPD2004 family of high-voltage silicon switching diodes from Central Semiconductor Corp. The family includes various configurations such as single, common anode, common cathode, and in-series arrangements. All variants share similar manufacturing processes and are intended for surface-mount applications requiring robust voltage handling capabilities.
