Product details
Overview
BUK98150-55A from Nexperia is an AEC-Q101-qualified N-channel TrenchMOS logic-level power MOSFET in SC-73 (SOT223) package, rated for 55 V drain-source voltage, 5.5 A continuous drain current at 5 V gate drive, and 150 mΩ RDS(on) at VGS = 5 V and Tj = 25 °C. It serves as a robust low-side switch in automotive 12 V/24 V load control circuits including solenoids, lamps, and small motors.
For engineers reviewing the BUK98150-55A datasheet, BUK98150-55A pinout, BUK98150-55A application, or BUK98150-55A equivalent, this page delivers verified electrical parameters, thermal resistance (Rth(j-sp) = 15 K/W), avalanche energy rating (22 mJ), gate charge (QG(tot) = 5.3 nC), and SOT223 pin mapping - all critical for automotive-grade power switching design validation and layout planning.
Technical Context
This device employs TrenchMOS technology to achieve low on-resistance with logic-level gate drive compatibility (VGS(th) max = 2.3 V, typ. 1.5 V at 25 °C). Its 4-pin SC-73 package features dual drain terminals for enhanced thermal and current handling capability.
The BUK98150-55A supports unclamped inductive switching with non-repetitive avalanche energy of 22 mJ and exhibits fast switching performance: td(on) = 8 ns, tr = 57 ns, td(off) = 16 ns, and tf = 13 ns under standard test conditions (VDS = 20 V, RL = 3.3 Ω, RG(ext) = 10 Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V - Maximum drain-source blocking voltage; defines safe operation in 24 V automotive systems with load-dump transients. |
| ID (continuous) | 5.5 A at Tsp = 25 °C, VGS = 5 V - Continuous current capability with logic-level gate drive; sufficient for medium-power solenoid and lamp loads. |
| RDS(on) | 128–150 mΩ at VGS = 5 V, ID = 5 A, Tj = 25 °C - Confirmed on-resistance enabling <1 W conduction loss at 5 A, critical for thermally constrained PCB layouts. |
| Ptot | 8 W at Tsp = 25 °C - Total power dissipation limit; combined with Rth(j-sp) = 15 K/W, sets junction temperature rise to ~120 °C under full load. |
| QG(tot) | 5.3 nC - Total gate charge value directly impacts required gate driver current and switching losses in PWM applications. |
| EDS(AL)S | 22 mJ - Non-repetitive avalanche energy rating; enables reliable operation in inductive load switching without external snubbers. |
| Ciss | 240–320 pF - Input capacitance affecting gate drive loop stability and high-frequency switching behavior. |
Pinout & Package
Package: SC-73 (SOT223), plastic surface-mounted package with increased heatsink area and 4 leads. Dual drain terminals (Pins 2 and 4) provide parallel current paths and improved thermal conduction to the PCB copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate (G) | Control terminal; accepts logic-level input (VGS = 4.5–5 V) to fully enhance the channel; requires ≤5.3 nC charge for full turn-on. |
| 2 | Drain (D) | High-side connection to load supply rail; electrically tied to Pin 4; used for current return path and thermal conduction to PCB. |
| 3 | Source (S) | Power ground reference; connects to system GND; source-drain diode forward voltage is 0.85–1.2 V at 5 A. |
| 4 | Drain (D) | Second drain terminal; internally connected to Pin 2; provides redundant current path and doubles thermal interface area to heatsink pad. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive critical applications per stress test requirements, supporting long-term reliability in engine bay and chassis environments. |
| Logic-level gate drive | VGS(th) range of 0.6–2.3 V ensures full enhancement with standard 3.3 V or 5 V microcontroller GPIO outputs without level-shifting circuitry. |
| Dual drain terminals | Pins 2 and 4 both connect to drain, reducing effective package resistance and improving thermal transfer to PCB copper, lowering Rth(j-sp) to 15 K/W. |
| Low RDS(on) @ 5 V | 128–150 mΩ at VGS = 5 V enables <0.75 W conduction loss at 3.5 A, minimizing heatsink requirements in space-constrained modules. |
| Unclamped avalanche ruggedness | 22 mJ single-pulse avalanche rating allows safe interruption of inductive currents (e.g., fuel injectors, relays) without external protection components. |

IC Role / Device Role / Timing Role: Bidirectional current-handling switch (via external H-bridge configuration); utilizes integrated source-drain diode (VSD = 0.85–1.2 V) for freewheeling. Use Value: Logic-level compatibility simplifies microcontroller interface; 55 V rating accommodates back-EMF spikes up to 44 V during motor deceleration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL10DN5LF5 | 55 V, 10 A, RDS(on) = 110 mΩ @ VGS = 4.5 V; PowerFLAT 5x6 package; higher current rating but larger footprint and no AEC-Q101 certification. | Higher current capacity suits larger motors but lacks automotive qualification; unsuitable for safety-critical BCM nodes requiring AEC compliance. | Select STL10DN5LF5 only for non-automotive 24 V industrial loads where higher ID and lower RDS(on) outweigh qualification needs. |
| IRLML6344TRPBF | 20 V, 4.3 A, RDS(on) = 42 mΩ @ VGS = 4.5 V; SOT-23 package; lower voltage rating and smaller thermal mass. | Not suitable for 24 V systems or automotive load-dump conditions; limited to low-power 12 V consumer electronics. | Choose IRLML6344TRPBF only for space-constrained, low-voltage (<16 V) applications where 55 V headroom and AEC-Q101 are unnecessary. |
Compared with STL10DN5LF5 and IRLML6344TRPBF, the BUK98150-55A uniquely balances AEC-Q101 qualification, 55 V rating, SOT223 thermal performance, and true logic-level drive - making it the only drop-in solution for automotive 12 V/24 V load switching where reliability, regulatory compliance, and PCB real estate are jointly constrained.
