LIMIT(MAX)
CONTROL Voltage............................................. - 0.3 V to 9 V
CONTROL Current..................................................... 100 mA
Storage Temperature.........................................-65 to 150 °C
Operating Junction Temperature(3) ....................-40 to 150 °C
Lead Temperature(4) ....................................................260 °C
Notes:
1. All voltages referenced to SOURCE, TA = 25 °C.
2. Related to transformer saturation – see Figure 13.
3. Normally limited by internal circuitry.
4. 1/16" from case for 5 seconds.
5. The Absolute Maximum Ratings specified may be applied,
one at a time without causing permanent damage to the
product. Exposure to Absolute Maximum Ratings for ex-
tended periods of time may affect product reliability.
