Highly approved SCALE technology

The award-winning drive circuit for IGBTs

IGBTs from 1700V to 3300V / 800A to 2400A

The 1SD418F2 are ultra-compact, intelligent, high performance, single-channel plug-and-play IGBT drivers of the intelligent the SCALE driver family.

They have been designed specifically for precise and reliable driving and protection of high-power, high-voltage IGBT modules in the standard 130x140mm and 190x140mm housings.

The 1SD418F2 drivers are based on CONCEPT's sophisticated SCALE driver chipset. The drivers are fully equipped with protection functions such as Vce-monitoring for short-circuit protection, operation inhibit after fault, supply undervoltage shut down.

The 1SD418F2 series drivers are featuring an active clamping function, which is the most rugged and best-performance way to protect the costly IGBTs.

Operating the gates with a bipolar control voltage (typically ±15V) allows the  IGBT modules to be driven reliably with high immunity to interferences.

Control signals are applied via fiber-optic links.

The on-board DC/DC converter provides a self-contained insulated power supply for the driver circuitry.

Note 1: Maximum switching frequency depends on the IGBT gate charge. See data sheet for actual value of specific driver.
