Note 1 Unless otherwise specified the NTE952 is specified from 0°C ≤ T_A ≤ +70°C. The maximum
junction temperature is 100°C. For elevated junction temperature the derating is based on
180°C/W junction to ambient with 0.4” leads from a PC board and 160°C/W junction to ambi-
ent with 0.125” lead length to a PC board.
