BTT60302EKAXUMA1 Overview
A high-side switch is a semiconductor relay that sits between the supply rail and the load, controlling current flow when turned on and providing both load-side protection and ground-referenced diagnostics. PROFET (Protected MOSFET) is Infineon's branding for its family of intelligent high-side switches that combine a power MOSFET with on-chip protection, diagnosis, and gate-drive circuitry; this part sits in the broader taxonomy of N-channel MOSFET -> power switch -> power management IC -> semiconductor, and is commonly used to replace electromechanical relays and discrete MOSFET-plus-driver arrangements.
Key features include integrated protection functions (short-circuit, over-load, over-voltage, over-temperature), current-limit trip thresholds set for safe activation of incandescent lamps and capacitive loads, an analog diagnostic current-sense output proportional to the load current, and dedicated ground-referenced input pins for each channel. The AEC-Q100 automotive-grade qualification, combined with the 28 V load-dump tolerance expected of 12 V automotive systems, makes it especially suitable for body-electronics modules, junction boxes, and BCMs.
The device is built on Infineon's SMART7 high-side technology platform, which adds digital status feedback, slew-rate control for EMI reduction, and a reverse-battery protection concept. Channels are independently controllable through CMOS-compatible input pins, allowing PWM-driven loads such as LEDs, solenoids, and DC motors.
Typical applications include automotive lighting (headlamps, tail lamps, turn signals), heating elements such as seat heaters and rear-window defrosters, DC motor drives (window lifters, door locks, mirror adjusters), solenoid and valve control, and replace-ment for traditional automotive relays and fuses in distributed body-electronic architectures.
When designing with this part, verify that the steady-state load current stays below the 4 A per-channel limit with adequate margin for inrush (lamp, capacitive, or motor loads). The exposed pad must be soldered to a sufficient PCB copper pour to keep junction temperature within the operating range; refer to Infineon's PROFET application notes for derating curves.

Typical Applications
BTT60302EKAXUMA1 is suitable for 6 applications: Automotive Lighting (Headlamps / Tail Lamps), DC Motor Drives (Window Lifter / Door Lock / Mirror), Seat Heater / Rear Window Defroster Control, Solenoid and Valve Drivers, Industrial 24 V Relay Replacement, Body Control Module (BCM) Load Driver.
Automotive Lighting (Headlamps / Tail Lamps)
The BTT60302EKAXUMA1's 28 V load-dump tolerance and 4 A per-channel continuous rating make it well suited for driving automotive front and rear lighting clusters. The 200 mOhm RDS(on) keeps steady-state conduction loss under 3.2 W per channel at 25C, while built-in short-circuit and over-temperature protection handle the inrush of cold incandescent or LED filaments. The current-sense diagnostic output feeds the BCM for lamp-out detection, and the PG-DSO-14 EP package allows direct PCB placement near the lamp connector.
Recommended
DC Motor Drives (Window Lifter / Door Lock / Mirror)
Body-control motors in 12 V automotive systems typically draw 3-5 A in steady state with much higher stall currents. The BTT60302EKAXUMA1 supports 4 A continuous and includes slew-rate control to reduce EMI, plus diagnostic feedback so the BCM can detect jammed mechanisms. The exposed thermal pad keeps junction temperature in check during repeated motor-start cycles, and the SOIC-14 footprint fits dense BCM layouts where multiple motors must be addressed from one PCB.
Recommended
Seat Heater / Rear Window Defroster Control
Resistive heating loads in seats and rear windows pull several amps continuously and demand reliable thermal shutdown if the load faults. The BTT60302EKAXUMA1's integrated over-temperature and over-load protection shut the channel off at defined thresholds, while its analog diagnostic current-sense output lets the BCM detect partial heating-element failure. Two channels per device mean a single IC can control both driver and passenger seat heaters, saving PCB area.
Recommended
Solenoid and Valve Drivers
Automotive transmission solenoids, EVAP purge valves, and HVAC mode doors require precise on/off control with diagnostic feedback for ECU fault detection. The BTT60302EKAXUMA1's CMOS-compatible input pins interface directly to 3.3 V or 5 V microcontroller outputs, and the integrated reverse-battery protection guards the ECU during jump-start or fault conditions. Two channels per package reduce BOM count for multi-solenoid modules.
Recommended
Industrial 24 V Relay Replacement
In industrial 24 V systems the BTT60302EKAXUMA1 can replace electromechanical relays, providing silent switching, longer lifetime, and integrated diagnostics. The 28 V nominal operating voltage covers 24 V industrial rails with margin, and the SOIC-14 EP footprint enables PCB-based relay replacement modules. The device's logic-level inputs interface with PLCs and microcontrollers without additional driver circuitry.
Recommended
Body Control Module (BCM) Load Driver
The BCM aggregates many low- to mid-current loads (lighting, mirrors, locks, wipers) and the BTT60302EKAXUMA1's two channels per package fit naturally into BCM layouts. Its exposed thermal pad handles the cumulative dissipation of multiple activated loads, and AEC-Q100 qualification plus 12 V load-dump tolerance cover the full automotive environment. The current-sense output simplifies ISO 26262 fault-monitoring design by providing analog feedback for each channel.

Key Differentiators
- Dual-channel high-side switch with 200 mOhm RDS(on) and analog current-sense diagnostics (vs BTS3205NHUSA1)
- Higher per-channel current capacity than many competing dual PROFETs (vs BTS428L2)
- Lower RDS(on) than older dual PROFETs in the same footprint (vs BTT6020-1ERA)
Design Notes
Estimated: At 4 A continuous load and 200 mOhm RDS(on) per channel, per-channel conduction loss at 25C is about 3.2 W. With both channels active the device dissipates up to 6.4 W; the PG-DSO-14 EP package requires a copper pour of at least 1 square inch on the exposed pad to keep theta_JA within automotive thermal limits. Always derate based on the Infineon thermal-resistance curves in the datasheet.
Place the BTT60302EKAXUMA1 close to the load connector to minimize the high-current trace length. Use wide copper pours on VS and OUT pins, and stitch the exposed thermal pad with multiple thermal vias to the inner PCB planes. Keep the logic input and diagnostic traces away from the high-current loops to avoid coupling noise into the BCM ADC inputs.
Do not exceed the load-dump transient rating of 36 V during jump-start or alternator field-collapse events. Confirm that the inrush current of capacitive or incandescent loads stays below the device's current-limit threshold - cold incandescent filaments can pull 10x steady-state current at turn-on. Verify the input-pin logic levels against the BCM's I/O voltage (3.3 V vs 5 V) since the BTT60302EKAXUMA1's input thresholds vary across PROFET generations.
Route the IS (current-sense) trace as a differential-style guarded trace back to the MCU ADC. Add a small RC filter at the MCU input to suppress switching transients; typical values are 10 kOhm + 100 nF. Avoid running IS traces parallel to OUT or VS traces to minimize capacitive coupling.
