## Absolute Maximum Ratings

The absolute maximum ratings define the safe stress limits beyond which permanent damage may occur:

* Drain-Source Voltage (V_DSS): 60 V
* Continuous Drain Current (I_D) at T_C = 25°C: 75 A
* Pulsed Drain Current (I_DM): 300 A
* Maximum Power Dissipation (P_D) at T_C = 25°C: 150 W
* Gate-Source Voltage (V_GS): ±20 V
* Maximum Junction Temperature (T_j): 150°C
* Storage Temperature (T_stg): –55°C to 150°C
* Avalanche Energy Capability (Single Pulse E_AS): 2.5 mJ

These parameters indicate the VN1160TR-E can operate under high-current, high-voltage pulses while requiring attention to thermal dissipation and PCB layout.

## Recommended Operating Conditions

The VN1160TR-E should be operated within the recommended ranges for safe and reliable performance:
