Product details

The Infineon BTS5240GNT is a dual-channel high-side power switch in a PG-DSO-20-21 package, rated for 5.4A maximum continuous output per channel with a typical on-resistance of 21 mOhm. It switches loads from 4.5V up to 28V, making it a fit for 12V and 24V automotive and industrial systems — lamp banks, solenoid drivers, relay coils, and small motor loads.

21 mOhm Rds(on) and integrated fault protection

The 21 mOhm typical Rds(on) keeps conduction losses low at full load — at 5.4A the dissipation is under 0.6W per channel, manageable in the SO-20 wide-body package with adequate PCB copper.

Temperature grade and operating envelope

The load supply spans 4.5V to 28V, covering nominal 12V and 24V rails with margin for transients.
