EL SEGUNDO, CA. September 1998 - International Rectifier (IR) now offers a new 28-pin LCC package -- a hermetically sealed surface mount replacement for the popular 14-pin side-braze package for Rad-Hard power MOSFETs. At 0.89 g, this new package features lighter weight and a smaller footprint than its leading counterpart, and offers a lower junction-to-case thermal resistance of 10.4°C/W/FET compared to 17°C/W/FET for competing parts.

The 28-pin LCC is very versatile and enables IR customers to specify a different number of die configurations. This package can be used with a quad (4 size 1 or size 2 FETs ), or any combination of IR Rad-Hard or standard dice, depending on their sizes. Standard combinations, such as 4 N-channel Rad-Hard (IRHQ7110), 4 P-channel Rad-Hard (-->IRHQ9110) and 2 N-/2 P-channel Rad-Hard (-->IRHQ6110) power MOSFETs are available. This surface mount version also offers a higher current capability than side-braze packages and can be used in full-bridge circuits for motor drive, power supply applications and linear regulators.

Samples can be located through International Rectifier's normal sales channels.
