Marking

Note 1: Ensure that the channel temperature does not exceed 150°C.

Note 2:

a) Device mounted on a glass-epoxy board (a)

b) Device mounted on a glass-epoxy board (b)

Note 3:

a) The power dissipation and thermal resistance values are shown for a single device

(During single-device operation, power is only applied to one device.).

b) The power dissipation and thermal resistance values are shown for a single device

(During dual operation, power is evenly applied to both devices.).

Note 4:

Note 5: Repetitive rating: pulse width limited by maximum channel temperature

Note 6:

• on lower left of the marking indicates Pin 1.
