N - channel enhancement mode POWER MOS field effect transistors. Easy drive and very fast switch­

ing times make these POWER MOS transistors ideal for high speed switching circuits in applica­

tions such as power actuator driving, motor drive including brushless motors, hydraulic actuators and many other uses in automotive applications. They also find use in DC/DC converters and uninterrupt­

ible power supplies.

ISOWATT220 PACKAGE

CHARACTERISTICS AND APPLICATION.

ISOWATT220 is fully isolated to 2000V dc. Its ther­

mal impedance, given in the data sheet, is optimi­

sed to give efficient thermal conduction together with excellent electrical isolation.

The structure of the case ensures optimum distan­

ces between the pins and heatsink. The ISOWATT220 package eliminates the need for ex­

ternal isolation so reducing fixing hardware. Accu­

rate moulding techniques used in manufacture assure consistent heat spreader-to-heatsink capa­

citance.

ISOWATT220 thermal performance is better the that of the standard part, mounted with a 0.1mm mica washer. The thermally conductive plastic has a higher breakdown rating and is less fragile than mica or plastic sheets. Power derating for ISOWATT220 packages is determined by:

THERMAL IMPEDANCE OF ISOWATT220 PACKAGE

Fig. 1 illustrates the elements contributing to the thermal resistance of transistor heatsink assembly, using ISOWATT220 package.

The total thermal resistance Rth (tot) is the sum of each of these elements.

The transient thermal impedance, Z,h for different pulse durations can be estimated as follows:

1 - for a short duration power pulse less than 1 ms;

Z t h < PfhJ-C

2 - for an intermediate power pulse of 5ms to 50ms:

Z th = PfhJ-C

3 - for long power pulses of the order of 500ms or greater:

R thJ-C + R thC-HS + R thHS-amb It is often possibile to discern these areas on tran­

sient thermal impedance curves.
