Overview
The CMUDM8004 TR PBFREE is a surface-mount P-channel enhancement-mode silicon MOSFET manufactured by Central Semiconductor Corp. It utilizes a P-Channel DMOS process and is housed in an SOT-523 package. The device features a drain-source voltage of 30 V, a continuous drain current of 450 mA, and a power dissipation rating of 250 mW at 25°C ambient temperature. Key electrical characteristics include a maximum on-resistance of 1.1 Ω at VGS=4.5V and ID=430mA, a gate threshold voltage of 1.0 V max at 250µA, and a total gate charge of 0.88 nC. It operates within a junction temperature range of -65°C to +150°C.
Feature Summary

- ESD protection rated up to 2kV
- Halogen-free design compliant with environmental standards
Applications
- Load/Power Switches
- Power Supply Converter Circuits
- Battery Powered Portable Devices
Procurement Notes
Verify the End-of-Life status indicated in PDN01276 Rev.001 (January 22, 2026), which classifies all devices in the SOT-23 family as discontinued. Confirm if available inventory allows for last-time buys or if alternative sourcing strategies are required due to the lack of official replacement part numbers listed for this specific component.
Selection Notes
Select this component for high-speed pulsed amplifier and driver applications requiring a compact surface-mount solution. Ensure the design accommodates the 30V drain-source voltage limit and the 450mA continuous current capability. Verify that the logic-level compatibility aligns with the system's control voltage levels to ensure proper switching performance.
Part Context
This component belongs to the UltraMini series from Central Semiconductor Corp, designed for space-constrained portable electronics. It is part of a broader portfolio of small-signal MOSFETs intended for low-power switching applications. The 'TR' suffix indicates tape-and-reel packaging, while 'PBFREE' denotes lead-free plating options.
Replacement Considerations
No public confirmed substitute part numbers are provided in the manufacturer's documentation for the CMUDM8004. The product notice lists it under discontinued items without suggesting direct replacements.
