Single-Channel SCALE™-1 Plug-and-Play Driver

This product is in End-of-Life status and is no longer available.
Suggested Alternative: 1SP0635

1SD418F2 single-channel, plug-and-play IGBT drivers are ultra-compact, high-performance and intelligent. They support 2-level, 3-level and multilevel converters and have been designed to precisely and reliably drive 1700 V to 3300 V IGBT modules packaged in standard 130 x 140 mm or 190 x 140 mm housings, while delivering optimum protection.

1SD418F2 drivers are based on CONCEPT's sophisticated SCALE-1 driver chipset. Drivers are fully equipped with protection functions including: Vce-monitoring for short-circuit protection; operation inhibit after fault; and supply undervoltage shut down. 

1SD418F2 series drivers feature an active clamping function, offering rugged and high-performance protection for costly IGBTs. 

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

Control signals are applied via fiber-optic links. 

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