PARAMETER

TSTG

Storage temperature range

TSOLD

TJ

Lead soldering temperature (10sec.)

Recommended max junction temperature2

θJA

Thermal impedance (N and A packages)

NOTE:

1. 100% measured in production.

2. The junction temperature is calculated from the following expression:

TJ = TA + θJA [(VEE x 0.015 x nIDL) + (VEE x 0.018 x nRX) + (VEE x 0.066 x nTX)]

where

TA = Ambient temperature in °C.

nTX =

Thermal resistance of package.
