## Electrical Specifications

* Drain-Source Voltage (Vds): 30V

* The maximum voltage that the device can withstand between the drain and source terminals is 30V.
* Gate-Source Voltage (Vgs): ±20V

* This specifies the maximum voltage that can be applied between the gate and source terminals.
* Continuous Drain Current (Id): 15A (at 25°C)

* The maximum continuous current that can flow through the MOSFET without exceeding thermal limits at a room temperature of 25°C.
* Pulsed Drain Current (Id, pulsed): 60A

* The MOSFET can handle pulsed current up to 60A for short periods, which is useful in transient conditions.
* On-Resistance (Rds(on)): 9.3mΩ at Vgs = 10V

* This low on-resistance ensures minimal power loss when the device is in the "on" state, making it highly efficient for power switching.
* Gate Threshold Voltage (Vgs(th)): 1-3V

* This is the voltage range at which the MOSFET starts to turn on, allowing current to flow between the drain and source.

## Thermal Characteristics

* Junction-to-Case Thermal Resistance (RthJC): 1.9°C/W

* This low thermal resistance between the junction and the case helps in efficient heat dissipation, ensuring that the MOSFET can operate safely in high-temperature conditions.
* Junction-to-Ambient Thermal Resistance (RthJA): 62.5°C/W

* This value indicates the ability of the MOSFET to dissipate heat into the surrounding environment. Lower values are better, as they indicate more effective heat management.
