Product details
Overview
BUK98180-100A/CU115 from Nexperia is a logic-level N-channel TrenchMOS FET in SC-73 (SOT223) package, rated for 100 V VDS, 4.6 A continuous drain current at 5 V gate drive, and 153 mΩ RDS(on) at VGS = 5 V and Tj = 25 °C. It is AEC-Q101 qualified and designed for automotive power switching of 12 V/24 V loads including motors, lamps, and solenoids.
For engineers reviewing the BUK98180-100A/CU115 datasheet, BUK98180-100A/CU115 pinout, BUK98180-100A/CU115 application, or BUK98180-100A/CU115 equivalent, this page delivers verified electrical parameters, thermal behavior, gate-drive compatibility with 3.3 V/5 V logic, and automotive-grade reliability context - all critical for high-reliability power stage design.
Technical Context
This device uses TrenchMOS technology to achieve low on-resistance while maintaining robust avalanche ruggedness (16 mJ unclamped) and stable threshold voltage (0.6–2.3 V across -55 °C to 150 °C). Its 4-pin SC-73 package integrates dual drain terminals for enhanced thermal conduction and current handling.
The FET supports logic-level gate drive down to 4.5 V, with typical RDS(on) of 201 mΩ at VGS = 4.5 V and 389 mΩ at 150 °C - enabling direct interface with microcontrollers and automotive body-control modules without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - Maximum blocking voltage for 12 V/24 V automotive systems with transient margin up to ISO 7637-2 Pulse 5a. |
| ID (continuous) | 4.6 A at VGS = 5 V, Tsp = 25 °C - Sustains motor stall currents in small DC brush motors and solenoid hold phases. |
| RDS(on) | 153 mΩ (typ) at VGS = 5 V, Tj = 25 °C - Limits conduction loss to ≤3.2 W at 4 A, enabling compact heatsinking. |
| EAS | 16 mJ (unclamped) - Withstands inductive energy from lamp/motor turn-off without external snubbers in many automotive loads. |
| VGS(th) | 1.5 V (typ) at Tj = 25 °C - Ensures reliable turn-on with 3.3 V MCU outputs and remains functional down to 0.6 V at 150 °C. |
| Ciss | 464 pF (typ) - Enables fast switching with low gate drive power; compatible with standard 10 Ω gate resistors. |
| Rth(j-sp) | 15 K/W - Junction-to-solder-point thermal resistance allows ≥4 W dissipation with 60 °C solder point rise, supporting PCB copper pour heatsinking. |
Pinout & Package
SC-73 (SOT223) plastic surface-mounted package with increased heatsink area and 4 leads; features dual drain terminals (Pins 2 and 4) for parallel current paths and improved thermal transfer to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | G | Gate input - Accepts 3.3 V/5 V logic signals; requires no level shifter; gate leakage <100 nA ensures low standby power. |
| 2 | D | Drain terminal 1 - Carries main load current; electrically tied to Pin 4; used for PCB thermal pad connection. |
| 3 | S | Source - Reference node for gate drive and current sensing; connects to ground or low-side return path. |
| 4 | D | Drain terminal 2 - Parallel path to Pin 2; doubles current-carrying capacity and improves thermal coupling to heatsink copper. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood applications per stress test requirements including temperature cycling, HTRB, and UHAST. |
| Logic-level gate drive | Guaranteed turn-on at VGS = 4.5 V - enables direct interface with 3.3 V MCUs and automotive CAN/LIN transceivers. |
| Dual drain terminals | Reduces effective package resistance by ~30% and lowers thermal impedance to PCB, improving power density vs. standard SOT223. |
| Robust avalanche capability | 16 mJ non-repetitive EAS - eliminates need for external clamping diodes in inductive load switching up to 4 A. |
| Low RDS(on) over temperature | RDS(on) increases only 2.5× from 25 °C to 150 °C - maintains predictable conduction loss in engine bay environments. |
Applications
| Automotive Body Control Module | 12 V DC Motor Driver |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL130N10F7 | 100 V, 130 A, 5.5 mΩ RDS(on); PowerFLAT 5x6 package; higher current, lower RDS(on), but not AEC-Q101 qualified. | Targeted at industrial motor drives, not automotive safety-critical functions. | Select when higher current and lower loss are needed, and automotive qualification is not required. |
| ON Semiconductor NTMFS5C675NL | 100 V, 100 A, 6.7 mΩ; SO-8FL package; AEC-Q101 qualified; significantly higher current rating and lower RDS(on). | Designed for high-power ADAS and infotainment power rails where space and thermal performance are constrained. | Choose for next-generation automotive platforms needing scalable power density and footprint reduction. |
Compared with STL130N10F7 and NTMFS5C675NL, BUK98180-100A/CU115 offers optimal balance of AEC-Q101 compliance, logic-level drive, and thermal performance in the cost-sensitive SOT223 form factor - making it ideal for legacy and mid-tier automotive power nodes where board space and qualification are prioritized over ultra-low RDS(on).

FAQ
Is BUK98180-100A/CU115 pin-compatible with standard SOT223 MOSFETs?
Yes - it uses the standard SC-73 (SOT223) footprint with Pins 1 (G), 2 (D), 3 (S), and 4 (D). Dual drain pins (2 and 4) are internally connected and may be routed to the same copper pour; no layout change is needed versus single-drain SOT223 parts.
What is the maximum continuous drain current at 100 °C solder point temperature?
Per Figure 2 in the datasheet, normalized ID derating is ~65% at Tsp = 100 °C, yielding ~3.0 A continuous drain current at VGS = 5 V - sufficient for sustained solenoid hold or fan motor operation in hot underhood conditions.
Does BUK98180-100A/CU115 include an integrated body diode? What is its forward voltage?
Yes - it features a monolithic source-drain body diode with VSD = 0.85 V (typ) at IS = 5 A and Tj = 25 °C. Reverse recovery time is 49 ns, and recovered charge is 130 nC - suitable for freewheeling in inductive loads without external diodes.
Can BUK98180-100A/CU115 be driven directly by a 3.3 V microcontroller GPIO?
Yes - its VGS(th) max is 2.3 V at -55 °C and min is 0.6 V at 150 °C, with guaranteed RDS(on) ≤201 mΩ at VGS = 4.5 V. At 3.3 V, it operates in linear region but delivers ~2.5 A with acceptable loss - adequate for many low-duty-cycle automotive loads.
