Lead Temperature (soldering, 10 seconds)
Note: Exceeding these ratings could cause damage to the device. All voltages are with respect to Ground.
Currents are positive into, negative out of the specified terminal.

Thermal Resistance from Junction to Ambient, θJA
220℃/W
Junction Temperature Calculation: TJ = TA + (PD ×θJA).
The θJA numbers are guidelines for the thermal performance of the device/pc-board system. Connect the ground pin to ground
using a large pad or ground plane for better heat dissipation. All of the above assume no ambient airflow.
