These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

These specifications apply for 0°C

LM329 is 100°C. For operating at elevated temperature. The TO-92 package, 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 ambient with 0.125″ lead length to a PC board.
