That is a standard three-lead DPak with a tab for thermal transfer to the PCB copper. The tab is the drain connection, so the footprint must tie it to the load voltage plane. No special reflow profile required — standard lead-free solder works. ## Protection and control — what the on/off interface expects The input is a non-inverting on/off logic pin — pull it high to turn the switch on. No external Vcc supply is needed; the gate drive is self-biased from the load voltage. The auto-restart feature means after an over-temperature fault clears, the switch turns back on automatically. That is useful for intermittent overloads like a stalled motor that clears when it cools, but it also means the load sees repeated on-off cycles during a sustained fault — something to keep in mind if the load is sensitive to power cycling. That means Infineon is still manufacturing it, and there is no end-of-life notice on the table. The HITFET family has been around long enough that the datasheet and application notes are mature. If you are qualifying a new design, there is no LTB clock ticking.","metaTitle":"Infineon BTS142DATMA1 HITFET Low-Side Power Switch, 4.6 A","metaDescription":"Infineon BTS142DATMA1 HITFET low-side power switch: 4.6 A output, 23 mOhm Rds(on), 42 V load max, -40 to 150°C.

The -40°C to 150°C junction temperature range and the 42 V maximum load voltage — which covers 12 V and 24 V systems with load-dump transients — make it suitable for automotive under-hood and chassis-domain environments.
