Typical Applications
BTS3060TFATMA1 is suitable for 6 applications: Automotive Door Lock Actuator Driver, Automotive Seat Heater Control, 12V Relay and Solenoid Driver, LED Lighting Module Driver, Industrial 24V PLC Output Module, Power Window and Sunroof Motor Driver.
Automotive Door Lock Actuator Driver
The BTS3060TFATMA1's 3 A continuous current rating and 50 mΩ RDS(on) make it well suited to driving 12V automotive door lock actuators that draw 1 to 3 A during the locking pulse. Embedded overcurrent protection handles stall conditions when the actuator jams, and the open-load status output lets the ECU distinguish between a successful lock and a wiring fault. Placed between the actuator return line and chassis ground, the device operates from standard 12V battery voltage with logic-level 3.3V or 5V gate drive from the body control module. The AEC-Q100 qualification supports deployment across passenger car and light commercial vehicle platforms.
Recommended
Automotive Seat Heater Control
The BTS3060TFATMA1 provides a clean low-side interface for PWM-controlled 12V seat heater pads that typically draw 2 to 4 A peak. The monolithically integrated N-channel MOSFET supports continuous switching at body-control PWM frequencies while the status pin provides diagnostic feedback to the climate module. Overtemperature shutdown protects the seat assembly if the heater pad is shorted or the cooling airflow is restricted. The 50 mΩ RDS(on) keeps conduction loss low enough that the device sustains continuous duty in the seat heater without a heatsink beyond the standard DPAK copper pour. AEC-Q100 qualification is required by OEMs for in-cabin occupant comfort systems.

12V Relay and Solenoid Driver
Engineers use the BTS3060TFATMA1 to switch small 12V automotive relays and solenoids that draw 1 to 3 A continuous with inrush peaks up to 5 A. The integrated N-channel MOSFET's avalanche capability absorbs the inductive kick when the coil de-energizes, while the overcurrent shutdown protects against welded-contact or short-circuit wiring faults on the load side. Driving the relay coil with a logic-level 3.3V or 5V GPIO is straightforward thanks to the device's TTL-compatible input threshold. The PG-TO252-3 footprint allows the same PCB layout to be reused for adjacent relay channels in a body controller or power distribution module.
Recommended
LED Lighting Module Driver
For 12V automotive LED modules such as interior ambient lighting, side-marker lamps, and rear combination lamps, the BTS3060TFATMA1 supplies a stable low-side switch that sinks the LED return current while the high-side feed is hard-wired to battery. Its 50 mΩ RDS(on) keeps the LED cathode close to ground, ensuring constant LED current when the module is dimmed via PWM from the BCM. Open-load detection flags burned-out LED strings to the driver module, and overtemperature protection prevents thermal runaway in enclosed lamp housings. The logic-level input accepts 3.3V or 5V PWM signals directly from the lighting controller.
Recommended
Industrial 24V PLC Output Module
Beyond automotive, the BTS3060TFATMA1 is well suited to 24V industrial PLC discrete output modules driving solenoid valves, indicator lamps, and small relays in factory automation panels. The 42 V drain rating provides comfortable margin above the nominal 24V supply and typical transients on long cable runs. Embedded protection functions eliminate the need for external fuses or PTC resettable devices on each output channel, reducing panel footprint. Status feedback to the PLC backplane enables per-channel fault diagnostics without additional wiring, and the PG-TO252-3 package is compatible with hand-soldered prototyping or fully automated SMT production.
Recommended
Power Window and Sunroof Motor Driver
Body-control modules use the BTS3060TFATMA1 to drive small DC motors for power window lift, sunroof actuator, and tailgate lock motors that draw 2 to 3 A running current with stall peaks above 5 A. The overcurrent protection detects stall conditions and shuts the device down before the motor or wiring harness overheats, while open-load detection flags broken wiring. The status output lets the ECU implement stall detection and end-of-travel soft-stop routines without extra current-sense circuitry. Logic-level 3.3V gate control aligns directly with body-control MCU GPIO outputs, simplifying the BOM and saving PCB area in space-constrained door modules.

Key Differentiators
- Balanced 3 A current class with 50 mΩ RDS(on) in HITFET family (vs BTS3050TFATMA1)
- Full diagnostic feedback with status pin (vs BTS3125TFATMA1)
- Single-channel monolithic integration reduces BOM (vs BTS50301EJAXUMA1)
Design Notes
Estimated: at 3 A continuous load and 50 mΩ RDS(on) (typ) on a 12 V automotive rail, conduction loss is approximately 0.45 W. With a DPAK footprint on 1 sq-in of 2 oz copper the junction-to-ambient thermal resistance is typically 50 C/W, producing a 22 C rise above ambient - well within the 150 C junction limit. Always validate against the worst-case load profile and ambient temperature for your enclosure.
The PG-TO252-3 thermal tab is the primary heatsink path and MUST be soldered to a PCB copper pour spanning at least the tab footprint plus 0.5 inch of 2 oz copper on top and inner layers. Use multiple thermal vias under the tab to spread heat into inner copper planes. The gate input trace should be kept short and routed away from switching nodes to avoid dv/dt-induced false turn-on.
Do not exceed 42 V on the drain pin even during transient events - automotive load-dump can exceed 35 V on a 12 V system. Add an external TVS diode (e.g., 33 V or 36 V clamp) on the supply feed if the upstream protection is unknown. The status pin is open-drain and requires an external pull-up to the logic rail; without the pull-up the diagnostic feedback is unreadable.
Compliance Information
AEC-Q100 qualified for automotive applications. RoHS and REACH compliant per Infineon product page. Halogen-free status not explicitly stated in verified data - confirm with manufacturer datasheet if required for the design.
