Product details

The Infineon BTS409L1 E3062A is a single-channel PROFET high-side power switch — it connects a 5 V to 34 V load to the supply rail under logic control, with integrated protection that saves board space. The 160 mOhm typical Rds(on) sets the conduction loss floor: at 1.8 A the dissipation is about 0.5 W, which the PG-TO263-5-2 package's exposed tab sinks to the board copper.

The 160 mOhm typical on-resistance is the value at 25°C junction; expect it to roughly double at 150°C junction. If the load draws 1.8 A continuously, the I²R loss at temperature could reach 1 W — that copper area on the PG-TO263-5-2 tab needs to be generous. The part includes over-temperature shutdown, so a marginal heatsink causes cycling rather than immediate failure, but the thermal pad layout should still follow the datasheet's recommended footprint.

Frequently asked questions

Is BTS409L1 E3062A obsolete?

Yes, the BTS409L1 E3062A is listed as Obsolete. Infineon no longer manufactures it, and no direct replacement order code is provided. Sourcing is through independent distribution against an RFQ.

What is the Rds(on) of BTS409L1?

The typical Rds(on) is 160 mOhm. This is the on-resistance at 25°C junction; expect it to increase with temperature, roughly doubling at the 150°C maximum junction temperature.
