Overview
The CMUDM7005 TR PBFREE is an N-channel enhancement-mode silicon MOSFET in a surface-mount SOT-523 package. It features a drain-source voltage of 20V, a continuous drain current of 650mA, and a power dissipation of 300mW at 25°C ambient temperature. The device offers a maximum gate-source voltage of 8V and a threshold voltage ranging from 0.5V to 1.1V. Key electrical parameters include a maximum on-resistance of 0.23Ω at VGS=4.5V and ID=600mA, and a total gate charge of 1.58nC at VDS=10V.
Feature Summary
- Logic level compatible with low threshold voltage for efficient drive
- ESD protection rated up to 2kV
- Designed for high-speed pulsed amplifier and driver applications
Applications
- Load and power switches
- Power supply converter circuits
- Battery-powered portable equipment
Procurement Notes
Verify the End-of-Life status indicated by 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.
Selection Notes
Select this component for low-voltage switching tasks requiring small form factors. Ensure the application operates within the 20V drain-source limit and 650mA continuous current rating. Verify that the logic interface can reliably drive the gate given the specified threshold voltage range and on-resistance characteristics under expected load conditions.
Part Context
This component belongs to Central Semiconductor's UltraMini series of surface-mount transistors. It utilizes an N-channel DMOS process optimized for speed and low resistance. The specific marking code for this device is '5C7'. It is packaged in the compact SOT-523 case R3 configuration.
Replacement Considerations
No public confirmed substitute part numbers are listed in the manufacturer's discontinuation notice (PDN01276). The document explicitly states 'N/A' for suggested replacements for the CMUDM7005.
