Overview
The EC4303C-TL is a P-channel enhancement mode MOSFET from onsemi, designed for low-voltage drive applications. It operates with a drain-source voltage (V_DSS) of -40V and a gate-source voltage (V_GS) of ±20V. The device features a typical on-resistance (R_DS(on)) of 15mΩ at V_GS = -10V and 20mΩ at V_GS = -4.5V. It supports a continuous drain current (I_D) of -18A at T_C = 25°C. The component is housed in an SOT-323 surface-mount package.
Feature Summary
- Optimized for low-voltage drive series applications
- Enhancement mode P-channel operation
- Low on-resistance for efficient power switching
Applications
- General-purpose switching circuits
- Low-side load switches
- Power management modules
Procurement Notes
Verify the specific suffix 'TL' against the official datasheet to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required thermal performance and pinout configuration for the target PCB layout. Cross-reference the manufacturer's latest documentation for any updates to electrical characteristics or compliance status.
Selection Notes
Select this component when a compact P-channel MOSFET is required for low-voltage drive scenarios. Evaluate the R_DS(on) values at -4.5V and -10V gate drives to ensure compatibility with the control logic levels. Consider the SOT-323 package size constraints and thermal dissipation requirements relative to the expected continuous drain current in the application.
Part Context
This part belongs to onsemi's standard product lineup, which includes discrete semiconductors for industrial and consumer electronics. The EC4303C-TL complements other N-channel and P-channel MOSFETs in the portfolio, providing options for various voltage ratings and package types to support diverse power management and signal switching needs.
Replacement Considerations
Check for direct substitutes such as the EC4403C-TL, noting potential differences in on-resistance and high-frequency performance. Verify that alternative components maintain compatible pinouts, voltage ratings, and package dimensions to ensure seamless integration without redesigning the circuit board.
