The Infineon BTS3060TFATMA1 is a single-channel, N-channel low-side power switch from the HITFET series. It switches grounded loads up to 3 A from a 42 V max supply rail, with a typical on-resistance of 50 mOhm. The On/Off interface needs no external Vcc — the gate drive is self-biased from the load voltage. Built-in fault protection covers current limiting (fixed), over-temperature shutdown, and over-voltage clamping, so it handles the kind of abuse a solenoid, lamp, or small relay throws at it in an automotive or industrial environment. The PG-TO252-3 package (DPak) is a common surface-mount footprint, and the junction temperature range of -40 to 150 °C means it can sit under the hood or inside a motor-drive cabinet without derating.
Fault protection set — no external clamp needed
Over-temperature shutdown and over-voltage clamping are on-chip. That saves a TVS diode and a PTC fuse on the board — one less component to qualify and one less thing to fail. The fixed current limiting protects the wiring and the load during a short-circuit event, though it does mean the switch will dissipate significant power until the thermal limit trips. For intermittent faults this is fine; for a hard-wired short, the thermal cycling will protect the silicon but the load side still sees the current-limit value until the junction hits the shutdown threshold.
No last-time-buy risk, no end-of-life notice to track.
