1FSD08110
Firstack 1FSD08110 plug-and-play IGBT gate driver, 8 W / 110 A, 1700-3300 V, for 140x190 mm and 140x130 mm modules.
The 1FSD08110 is a Firstack plug-and-play gate driver with an optical-fibre interface, developed for high-voltage and high-power IGBT modules in the 140x190 mm and 140x130 mm high-power module packages. It provides an 8 W drive power, a 110 A peak output current and a 1700 V or 3300 V maximum breakdown voltage, and it supports both 2-level and multi-level converters. The digital driver optimises the switching performance of the IGBT and provides comprehensive protection, including VCE short-circuit monitoring, a di/dt protection path, undervoltage lockout, soft shutdown, digitally dynamic advanced active clamping and multi-level turn-off. The optical-fibre interface gives galvanic isolation and immunity to electromagnetic interference, which suits the harsh environment of rail, renewable and high-voltage transmission equipment. A fault is reported to the controller through the fibre, and when no PWM signal is present the gate stays in the negative-voltage off state. Every device is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. Designers should confirm the module package and set the gate resistors for the module. BeiLuo holds this driver in stock and our FAE team supports driver selection and validation.
FAE Professional Review
The 1FSD08110 is the workhorse plug-and-play driver for large high-power modules, with a robust DC/DC that survives a gate-emitter short and a soft shutdown that keeps the turn-off spike low. The fibre interface makes it a natural fit for rail and high-voltage converters. Confirm the module package and set the gate resistors.

Frequently Asked Questions
What modules suit the 1FSD08110?
It suits high-voltage, high-power IGBT modules in the 140x190 mm and 140x130 mm high-power packages at 1700 V or 3300 V. It supports both 2-level and multi-level converters.
For a 4500 V or 6500 V module, the HV1027P is the right driver.
Why use a soft shutdown?
During a short circuit, turning the IGBT off as fast as normal would produce a large di/dt and a voltage spike that could destroy the device. A soft shutdown reduces the gate voltage slowly, so the fault current falls without an overvoltage spike, and the module turns off safely.
Our FAE team can explain the short-circuit sequence.
How do I set the gate resistors?
The driver provides fixed gate resistor positions, and Firstack publishes recommended values for common IGBT modules. Start from the recommendation, then tune on the bench, and note that some models use multi-level turn-off with several resistors.
