Claim 11:
12. A capacitive discharge unit (CDU) for detonating an explosive in response to a control signal, the capacitive discharge unit comprising:
a plurality of CDU components including:
an exploding foil initiator (EFI);
a trigger circuit;
a firing capacitor; and
an insulated-gate bipolar transistor IGBT firing switch; and

a board for mechanically and electrically supporting the trigger circuit, the EFI, the firing capacitor, and the IGBT firing switch, the CDU having an axial length defined by an ordered arrangement along a CDU axis of two or more of the EFI, the firing capacitor, and the IGBT firing switch, wherein the trigger circuit is mounted on the board and laterally offset from the CDU axis such that the trigger circuit does not contribute to the axial length;
wherein the axial length of the CDU comprises a first linear portion including the IGBT firing switch and a second linear portion including a remainder of the plurality of CDU components in the ordered arrangement, and wherein the first linear portion has an axial length that is not more than 35% of the axial length of the CDU.
