blanking time ................................................. 0.1 x I

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, T

A = 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.
