The FGB3040CS is a standard current sense ignition IGBT that lowers power dissipation by 30% and reduces heat in automotive applications by eliminating the need for a high current sense resistor. It uses a Kelvin-ground to improve current sense accuracy, eliminates the gate-to-emitter input resistor to simplify the IGBT gate control. The typical clamping voltage is 400 V.

The device replaces the high power sense resistor with a smaller, low current sense resistor. It uses lead-free terminals and is characterized for moisture sensitivity in accordance with the lead-free reflow requirements of the joint IPC/JEDEC standard J-STD-020.
