Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality

should not be assumed, damage may occur and reliability may be affected.

4. Repetitive rating: pulse width limited by maximum junction temperature.

5. L = 51 mH, starting TJ = 25°C.

6. Meets JEDEC standards JESD 22−A114 and JESD 22−C101.

7. All items are tested with the standards JESD 51−2 and JESD 51−10.

8. QJA free−standing, with no heat−sink, under natural convection.

9. QJC junction−to−lead thermal characteristics under QJA test condition. TC is measured on the source #7 pin closed to plastic interface for

QJA thermo−couple mounted on soldering.

10.QJT junction−to−top of thermal characteristic under QJA test condition. Tt is measured on top of package. Thermo−couple is mounted in

epoxy glue.
