Overview
The CMUDM8005 TR PBFREE is a surface-mount silicon P-channel enhancement-mode MOSFET manufactured by Central Semiconductor. It utilizes a P-Channel DMOS process for high-speed pulsed amplifier and driver applications. The device features low on-resistance and low threshold voltage, housed in an SOT-523 package. Key electrical parameters include a drain-source voltage of 20 V, continuous drain current of 650 mA, and power dissipation of 300 mW at 25°C. Operating temperatures range from -65°C to +150°C.
Feature Summary
- ESD protection up to 1800V (Human Body Model)
- Logic level compatible with low threshold voltage
- Very low rDS(ON) characteristics
Applications
- Load/Power switches
- Power supply converter circuits
- Battery powered portable equipment
Procurement Notes
Verify the End-of-Life status indicated in PDN01276 Rev:001 issued January 22, 2026. Confirm if available inventory allows for last-time buys or if alternative sourcing is required. Ensure the ordering suffix matches the desired plating type, as no suffix may result in either lead-free or tin/lead plated product depending on availability.
Selection Notes
Select this component for designs requiring small form factor P-channel switching in battery-powered devices. Verify that the 20V drain-source voltage rating meets circuit requirements. Consider the 300mW power dissipation limit and ensure adequate thermal management on the PCB mounting pad area.
Part Context
This part belongs to the Central Semiconductor UltraMini series of surface-mount transistors. It is designed specifically for space-constrained portable electronics where low on-resistance and fast switching speeds are critical. The SOT-523 package provides a miniature footprint suitable for automated surface mount assembly processes.
Replacement Considerations
Central Semiconductor has transitioned this device to End of Life status per PDN01276. No suggested replacement part numbers are provided in the official notice. Contact Central Semiconductor customer service for assistance locating an alternate source.
