Dual-Channel SCALE™-1 Plug-and-Play Drivers for 130 x 140 mm Dual IGBT Modules

This product is in End-of-Life status and is no longer available.

The 2SB315A is a dual-channel driver based on CONCEPT?s 2SD315AI SCALE-1 driver core, a proven technology for the reliable driving and safe operation of IGBTs. Drivers are fully equipped with protection functions including: Vce-monitoring for short-circuit protection; operation inhibit after fault; and supply-undervoltage shutdown.

The driver is matched to dual IGBT modules measuring 130 mm x 140 mm. Plug-and-play configuration allows immediate operation after mounting, so the user needs to invest no time and effort in designing or adjusting the driver for a specific application.
The driver supplies a gate current of ±15 A. Operating the gates with a bipolar control voltage (typically ±15 V) allows the IGBT modules to be driven reliably with a high level of immunity to interference.

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

The on-board DC/DC converter provides a self-contained, isolated power supply of 3 W per channel.

The DIC20 electrical interface operates with a 15 V logic level to ensure high noise immunity. 
The driver supports two independent driver channels or a half-bridge with internal dead-time generation.

Highest Reliability
SCALE-1 drivers have been established as an industrial standard since 1999. They have been used in numerous industrial and traction applications.
