Pinout

The IRLML5203TRPBF is a P-channel MOSFET in a SOT-23-3 package with 3 pins:
1. Gate (G) – Controls the switching.
2. Drain (D) – Connected to the load.
3. Source (S) – Connected to the power supply.
Key Features:
- Voltage Rating: -30V
- Current Rating: -5.3A (continuous)
- Low On-Resistance (RDS(on)): ~22mΩ @ VGS = -10V
- Logic-Level Gate Drive (works with low-voltage control signals).
Commonly used in power switching, load control, and DC-DC conversion.

Application

The IRLML5203TRPBF, a P-channel MOSFET, is commonly used in:
1. Power Management – Switching and load switching in portable devices.
2. Battery Protection – Reverse polarity and discharge control.
3. DC-DC Converters – Efficient power conversion in low-voltage applications.
4. Motor Control – Small motor drivers in consumer electronics.
5. LED Drivers – Dimming and power regulation for LEDs.
Its compact SOT-23 package and low on-resistance make it ideal for space-constrained, low-power applications.

Package

The IRLML5203TRPBF is a MOSFET transistor packaged in a SOT-23-3 (Small Outline Transistor) surface-mount package. This compact, 3-pin package is widely used for low-power applications, offering good thermal performance and space efficiency. The "TR" suffix indicates it comes on a tape-and-reel for automated assembly.

Frequently Asked Questions


Q: What is the maximum drain current for this P-Channel MOSFET?
A: The IRLML5203TRPBF can handle a continuous drain current (Id) of 3A at 25°C ambient temperature.


Q: What is the typical gate threshold voltage for this device?
A: The maximum gate threshold voltage (Vgs(th)) is 2.5V at a drain current of 250µA, ensuring logic-level drive capability.


Q: Can this MOSFET be driven directly by a 3.3V microcontroller?
A: Yes, but it is optimized for 4.5V to 10V gate drive. At 3.3V, conduction losses may increase due to higher Rds(on).


Q: What is the maximum power dissipation of the IRLML5203TRPBF?
A: The maximum power dissipation is 1.25W at ambient temperature (Ta), suitable for low-power surface-mount designs.


Q: What package type is used for this MOSFET?
A: It is housed in a Micro3/SOT-23 surface-mount package (TO-236-3, SC-59, SOT-23-3), ideal for compact PCB layouts.


Q: Does this component support high-frequency switching applications?
A: Yes, with a typical gate charge (Qg) of 14nC at 10V and input capacitance of 510pF, it is suitable for moderate-speed switching.
