BTS640S2G Description

Short technical summary and product information.

The Infineon BTS640S2G is a smart high-side power switch based on N-channel vertical power FET technology. It is designed for 12V and 24V DC grounded loads, replacing traditional electromechanical relays and fuses.

Key electrical specifications include an operating voltage range of 5.0 to 34V, an on-state resistance of 30 mΩ, and a load current capacity of 12.6A (ISO). The device also features current limitation up to 24A.

This power switch integrates several protective functions such as short circuit protection, overload protection, thermal shutdown, and undervoltage/overvoltage shutdown with auto-restart. It also provides proportional load current sense and an open-drain diagnostic output.

The BTS640S2G is available in TO220-7-11, TO263-7-2, and TO220-7-12 packages, supporting both through-hole and surface mount applications. It is AEC qualified and RoHS compliant.
