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 DATA

M PACKAGE:

Thermal Resistance-Junction to Ambient, θJA

D PACKAGE:

Thermal Resistance-Junction to Ambient, θJA

DM PACKAGE:

Thermal Resistance-Junction to Ambient, θJA

Junction Temperature Calculation: TJ = TA + (PD × θJA).

The θJA numbers are guidelines for the thermal performance of the device/pc-board system.

All of the above assume no ambient airflow.

95 OC/W

120 OC/W

165 OC/W
