When an internal diode is required, the suffix D is added to the part number as shown in the table.

* Package Type 2 available, contact Pickering for more details.

Note2: Capacitance across open switch

The capacitance across the open switch was measured with other connections guarded.

Note3: Capacitance values

The value will depend upon on the mode of connection/guarding of unused terminals. Please contact technical sales for

details.

Note4: Insulation resistance

Insulation resistance will reduce at higher temperatures. For more information on temperature effects
