Claim 16:
17. A munition comprising:
a chassis containing a payload having a quantity of explosive material; and
a fuzing unit arranged with the explosive material, the fuzing unit configured to initiate detonation of the explosive material using a capacitive discharge unit (CDU), the CDU comprising:
an exploding foil initiator (EFI);
a trigger circuit;
a firing capacitor; and
an insulated-gate bipolar transistor IGBT firing switch, the IGBT firing switch including:
a die encased in a package, the die having an IGBT chip; and
a gate pin, a collector pin, and an emitter pin, the collector pin and emitter pin each including one or more individual pins having a first end portion electrically connected to the die and an opposite end portion extending outward from the package, and the collector pin having a first end electrically connected to one or more substrate layers of the die and an opposite end extending outward from the package, wherein the gate pin is positioned adjacent to, at most, one of the collector pin and the emitter pin, and wherein a separation between the collector and emitter pins provides about a 2000V isolation; 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 offset from the CDU axis such that the trigger circuit does not contribute to the axial length.
