PACKAGE PIN OUTS
Note 1. 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.
M PACKAGE:
THERMAL RESISTANCE-JUNCTION TO AMBIENT,
θθθθθ
JA
95°C/W
DM PACKAGE:
THERMAL RESISTANCE-JUNCTION TO AMBIENT,

Junction Temperature Calculation:
T
J = TA + (PD x θJA).
The
θ
JA
numbers are guidelines for the thermal performance of the device/pc-board system.
All of the above assume no ambient airflow.
