7 TO-220 with staggered Lead Form (PA240CX)

7 DDPAK Surface Mount Package (PA240CC)

DESCRIPTION

The PA240 is a high voltage monolithic MOSFET opera-

tional amplifier achieving performance features previously

found only in hybrid designs while increasing reliability. Inputs

are protected from excessive common mode and differential

mode voltages. The safe operating area (SOA) has no second

breakdown limitations. External compensation provides the

user flexibility in choosing optimum gain and bandwidth for

the application.

The PA240 is packaged in two standard package designs.

The surface mount version of the PA240, the PA240CC,

is an industry standard non-hermetic plastic 7-pin DDPAK.

The through hole version of the PA240, the PA240CX, is an

industry standard non-hermetic plastic 7-pin TO-220 package.

The PA240CX is a staggered lead formed option that offers

industry standard 100 mil spacing. This allows for easier PC

board layout. (Please refer to package drawings for outline

dimensions.)

High voltage considerations should be taken when design-

ing board layouts for the PA240. The PA240 may require a

derate in supply voltage depending on the spacing used for

board layout. The 15-mil and 14-mil minimum spacing of the 7

TO-220 and 7 DDPAK respectively is adequate to standoff the

350V rating of the PA240. However, a supply voltage derate to

250V is required if the spacing of circuit board artwork is less

than 11 mils. In cases where the PA240 is used to its maximum

voltage rating, the PA240CX is recommended given that the

staggered lead form allows for 100-mil standard spacing.

The metal tabs of both the PA240CC and PA240CX pack-

ages are isolated in excess of full supply voltage.
