Features

The CSD17556Q5B is a 30V N-channel MOSFET from Texas Instruments, optimized for high-efficiency power conversion. Key features:
- Low On-Resistance (R_DS(on)): 1.8 mΩ (max) at V_GS = 10V, reducing conduction losses.
- High Current Handling: 100A continuous drain current (I_D).
- Fast Switching: Low gate charge (Q_G) and output capacitance (C_OSS) for improved efficiency in high-frequency applications.
- Thermal Performance: 5x6mm SON (DFN) package with exposed pad for enhanced heat dissipation.
- Logic-Level Gate Drive: Fully enhanced at 4.5V (V_GS), compatible with 5V controllers.
- AEC-Q101 Qualified: Suitable for automotive applications.
Ideal for DC-DC converters, motor drives, and power management in automotive/industrial systems.

Pinout

The CSD17556Q5B is a N-channel MOSFET in a 5-pin (SON) package (5x6mm).
Pin Functions:
1. Gate (G) – Controls the MOSFET switching.
2. Drain (D1, D2, D3) – Three pins internally connected to the drain for lower resistance and better thermal performance.
4. Source (S) – Output/return path.
Key Features:
- 30V drain-source voltage (V_DS)
- 5.6mΩ typical R_DS(on) (at V_GS = 10V)
- High current handling (up to 75A continuous)
Designed for power switching in applications like DC-DC converters, motor drives, and load switches.

Application

The CSD17556Q5B is a 30V N-channel MOSFET by Texas Instruments, commonly used in:
1. Power Management – DC-DC converters, voltage regulators.
2. Motor Control – Brushed DC and stepper motor drivers.
3. Load Switching – Power distribution in portable devices.
4. Battery Protection – Discharge control in power tools, drones.
5. Automotive Systems – LED drivers, infotainment power circuits.
Its low on-resistance (1.7mΩ) and high current handling (100A) make it ideal for high-efficiency, compact designs.

Package

The CSD17556Q5B is a 40V, 5.2mΩ N-channel MOSFET in a 5-pin PowerPAK® SO-8 package.
