Operating Junction Temperature
Plastic (DB, PW Packages) .......................................................................... 150°C
Storage Temperature Range ..............................................................-65°C to 150°C
Lead Temperature (Soldering, 10 seconds) .................................................... 300°C
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.

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