Safe Operating Area (BTS6133DAUMA1)
Typical Applications
BTS6133DAUMA1 is suitable for 7 applications: Automotive Headlamp Driver, Seat Heater Load Switch, Industrial 24V Solenoid / Valve Driver, Body Control Module (BCM) Protected Output, DC Motor Driver (Forward Direction), LED Lighting Driver / Strip Switch, Relay Replacement Module.
Automotive Headlamp Driver
The BTS6133DAUMA1's 8A continuous / 41A peak current rating and AEC-Q100 qualification make it ideal for driving halogen or LED headlamp modules from a 12V automotive battery rail. With integrated short-circuit and over-temperature protection plus diagnostic feedback, the part reduces wiring harness complexity by eliminating the mechanical relay and fuse, while providing fault status back to the BCM via the diagnostic pin. Typical deployment uses a 100 nF ceramic decoupling capacitor on VBB and a 10 kohm pull-up on the status pin for open-drain fault signaling.
Recommended
Seat Heater Load Switch
For heated-seat carbon-foil loads drawing 5 to 7A continuous, the BTS6133DAUMA1's 8A rating and PWM-capable input enable precise duty-cycle temperature control without a relay. The exposed DPAK tab dissipates up to 2W continuous to a small copper pour on the seat module PCB, while the diagnostic pin differentiates between open-load, short-to-ground, and over-temperature conditions for ISO 26262 fault logging. A 100 nF X7R ceramic on VBB and a TVS clamp (e.g., SMAJ24CA) protect against load-dump transients.
Recommended
Industrial 24V Solenoid / Valve Driver
The BTS6133DAUMA1 is well suited as a 24V industrial solenoid or hydraulic-valve driver in PLC output modules, where its diagnostic feedback reports open-load and short-circuit conditions to the PLC CPU without external sense resistors. With inductive-load clamping on-die, the part handles the turn-off energy of small to mid-size 24V coils directly; an external TVS is recommended for coils storing more than 50 mJ. The PG-TO252-5-11 footprint supports standard DPAK land patterns on FR4 industrial control PCBs.
Recommended
Body Control Module (BCM) Protected Output
Inside a vehicle BCM, the BTS6133DAUMA1 acts as a protected high-side driver for miscellaneous loads such as horn, wiper motor, washer pump, and interior lighting. The integrated current limit and thermal shutdown eliminate the need for a discrete PTC or blade fuse on each output, reducing BOM and harness complexity. The diagnostic pin feeds the BCM microcontroller for ISO 14229 UDS fault-status reporting (DTC P0xxx-series load fault codes).
Recommended
DC Motor Driver (Forward Direction)
For low-power 12V brushed DC motors such as window lifters, mirror adjusters, or sunroof drives drawing under 8A continuous, the BTS6133DAUMA1 provides forward-direction drive with full protection. PWM input control via the IN pin enables soft-start and variable-speed operation, while the integrated clamp absorbs the motor's inductive turn-off energy. For reverse-direction control, two BTS6133DAUMA1 units form an H-bridge, or pair with a complementary low-side switch such as IPD060N03LGATMA1.
Recommended
LED Lighting Driver / Strip Switch
The BTS6133DAUMA1 drives 12V or 24V LED lighting strips and automotive interior lighting modules, where its PWM capability provides dimming and its diagnostic pin reports open-circuit LED failures to the lighting controller. With 8A continuous capability, it can drive LED strings totaling up to ~100W at 12V, simplifying thermal design by distributing dissipation across multiple parallel channels rather than one over-stressed MOSFET. A 100 nF X7R bypass on VBB and a small ferris bead on the output minimize conducted EMI.
Recommended
Relay Replacement Module
As a direct solid-state replacement for automotive PCB relays, the BTS6133DAUMA1 eliminates mechanical wear, contact bounce, and audible click while adding diagnostic feedback unavailable from an electromechanical relay. Common drop-in replacement applications include horn relay, fog-lamp relay, and A/C compressor clutch relay. The exposed DPAK tab provides the same heatsinking footprint as a standard automotive PCB relay socket, simplifying retrofits.

Key Differentiators
- Higher continuous load current in same PG-TO252-5-11 footprint (vs BTS4130QGAXUMA1)
- Diagnostic feedback and integrated protection (vs BSD235CH6327XTSA1)
- AEC-Q100 automotive grade qualification (vs Non-automotive discrete MOSFETs)
Design Notes
The PG-TO252-5-11 (DPAK) package dissipates up to ~2W continuous through its exposed metal tab. Solder the tab to a copper pour of at least 1 cm squared on the top or bottom PCB layer; for continuous 8A loads, place thermal vias under the tab to a bottom-layer copper plane. Estimated: at 8A load with 0.1V drop, dissipation is ~0.8W; with 0.5V drop (cold lamp inrush), dissipation can spike to 4W transiently. Verify junction temperature under worst-case ambient using the datasheet thermal resistance curves.
Place a 100 nF X7R ceramic bypass capacitor as close as physically possible to the VBB pin (pin 2) and a second 1 uF bulk capacitor within 5 mm to suppress voltage transients during load-dump events. For 12V automotive systems, add an SMAJ24CA or similar bidirectional TVS across VBB to GND to clamp ISO 7637-2 pulse-1/pulse-2a transients that exceed the part's absolute maximum ratings.
Route the high-current output trace (pin 1, OUT) with a minimum 50 mil copper width at 1 oz copper, increasing to 100 mil or 2 oz copper for sustained 8A operation. Keep the IN logic trace (pin 4) and the ST/DIAG trace (pin 5) away from switching nodes; add a small RC filter (10 kohm + 100 pF) on the diagnostic line if the trace length exceeds 30 mm to suppress radiated EMI coupling into the BCM ADC.
Estimated thermal stress: at 12V nominal with a cold halogen headlamp filament (inrush resistance ~0.2 ohm, drawing 60A for 10 ms), the BTS6133DAUMA1's current-limit feature will engage and clamp the inrush to its safe-operating window. Verify that the application's inrush envelope falls within the SOA curve (referenced in the datasheet) before relying on cold-filament soft-start without additional inrush limiting. Adding an NTC thermistor or pre-charge resistor in series with the load eliminates the issue entirely.
When driving the IN pin from a 3.3V or 5V microcontroller GPIO, ensure the logic-high level meets the BTS6133DAUMA1's input-threshold specification (typically VIH >= 2.0V). For long cable harness connections (BCM to rear lamp), add a 10 kohm pull-down on IN to prevent floating-input parasitic turn-on during harness inductance ringing. The ST/DIAG pin is open-drain and requires an external pull-up resistor (typically 10 kohm to 5V) for fault signaling.
