Product details
Overview
BUK9880-55A from Nexperia is an AEC-Q101-qualified N-channel TrenchMOS logic-level power FET in SC-73 (SOT223) package, rated for 55 V drain-source voltage, 7 A continuous drain current at 5 V gate drive, and 8 W total power dissipation. It delivers low on-resistance of 68–80 mΩ at VGS = 5 V and Tj = 25 °C, enabling efficient 12 V/24 V automotive load switching in motors, lamps, and solenoids.
For engineers reviewing the BUK9880-55A datasheet, BUK9880-55A pinout, BUK9880-55A application, or BUK9880-55A equivalent, key selection criteria include its logic-level gate drive compatibility (VGS(th) max 2.3 V), avalanche ruggedness (36 mJ unclamped), thermal resistance (Rth(j-sp) = 15 K/W), and automotive qualification per AEC-Q101.
Technical Context
This device uses TrenchMOS technology to achieve low RDS(on) with stable threshold voltage across temperature (VGS(th) = 0.6–2.3 V from −55 °C to 150 °C). Its gate charge profile (QG(tot) = 11 nC, QGD = 4.6 nC) supports fast switching with controlled dV/dt, while integrated source-drain diode enables freewheeling in inductive loads.
The SC-73 package features dual drain leads for enhanced thermal conduction and current handling, with solder-point referenced thermal resistance optimized for PCB heatsinking. Avalanche energy rating (36 mJ) and peak drain current (30 A) support robust operation under transient overloads in automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V - Maximum blocking voltage compatible with 24 V automotive systems with margin. |
| ID (continuous) | 7 A at VGS = 5 V, Tsp = 25 °C - Sustains typical motor/lamp loads without forced cooling. |
| RDS(on) | 68–80 mΩ at VGS = 5 V, ID = 8 A, Tj = 25 °C - Enables <1 W conduction loss at 7 A, reducing thermal stress. |
| QG(tot) | 11 nC - Low gate charge allows efficient driving from microcontroller GPIOs or low-power gate drivers. |
| EDS(AL)S | 36 mJ (unclamped) - Withstands single-pulse inductive energy spikes without failure in solenoid/motor control. |
| Rth(j-sp) | 15 K/W - Enables direct thermal coupling to PCB copper pour for passive heatsinking in space-constrained modules. |
| VGS(th) | 0.6–2.3 V - Ensures reliable turn-on with 3.3 V or 5 V logic-level sources across full temperature range. |
Pinout & Package
SC-73 (SOT223) plastic surface-mounted package with increased heatsink area and 4 leads; thermally optimized for PCB solder-point cooling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate (G) | Control input; accepts logic-level voltages (3.3 V/5 V); low input capacitance (Ciss = 438–584 pF) minimizes driver loading. |
| 2 | Drain (D) | High-side power output; electrically and thermally connected to exposed pad for current path and heat transfer. |
| 3 | Source (S) | Power return node; referenced to ground in low-side switch configurations; carries full load current. |
| 4 | Drain (D) | Second drain terminal - paralleled with Pin 2 to reduce package inductance and improve thermal spreading. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive critical applications including engine control, body electronics, and ADAS subsystems. |
| Logic-level gate drive | Turns fully on with standard 3.3 V or 5 V MCU outputs - eliminates need for level-shifting or dedicated gate drivers. |
| Dual drain terminals | Reduces package resistance and inductance while doubling thermal conduction path to PCB heatsink. |
| Unclamped avalanche rating | 36 mJ energy tolerance enables safe operation during inductive flyback without external snubbers in lamp/motor circuits. |
| Low RDS(on) at 4.5 V | 89 mΩ max at VGS = 4.5 V ensures stable performance even with marginal gate drive voltage drop. |
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 power FET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP16NF06L | 60 V VDS, 16 A ID, TO-220 package, RDS(on) = 55 mΩ @ 10 V - higher current but requires external heatsink and 10 V gate drive. | Not AEC-Q101 qualified; suited for industrial power supplies rather than automotive safety-critical functions. | Select only if higher current and non-automotive use case justify larger footprint and absence of automotive qualification. |
| IRLR7843PbF | 40 V VDS, 30 A ID, DPAK package, RDS(on) = 12 mΩ @ 10 V - lower RDS(on) but insufficient voltage margin for 24 V systems with transients. | Lacks avalanche rating and automotive qualification; used in consumer-grade motor drives and battery tools. | Choose only for cost-sensitive 12 V-only applications where 40 V rating and no AEC compliance are acceptable. |
Compared with STP16NF06L and IRLR7843PbF, the BUK9880-55A uniquely balances automotive qualification, logic-level drive, 55 V rating, and SC-73 thermal performance - making it the only option among the three suitable for AEC-compliant 12 V/24 V load switching without external gate drivers or heatsinks.

FAQ
What is the maximum junction temperature rating for the BUK9880-55A?
The BUK9880-55A has a maximum junction temperature (Tj) of 150 °C, validated per AEC-Q101 requirements. This rating supports operation in under-hood automotive environments and enables sustained 7 A current at elevated ambient temperatures when mounted on adequately sized PCB copper heatsinks.
Does the BUK9880-55A require a gate resistor for safe operation?
The BUK9880-55A does not mandate a gate resistor for basic functionality, but a 10 Ω external resistor is recommended to control dV/dt and suppress ringing during fast switching - especially in inductive load applications like motors and solenoids where the device's 118 ns rise time and 32 ns fall time can induce voltage overshoot.
Is the BUK9880-55A suitable for high-frequency PWM motor control?
Yes, the BUK9880-55A supports PWM frequencies up to 20 kHz in typical 12 V motor control applications due to its low gate charge (11 nC), fast switching times (td(on) = 8 ns, tf = 32 ns), and low output capacitance (Coss = 87–104 pF), enabling efficient operation with minimal switching losses.
How is thermal performance measured for the BUK9880-55A?
Thermal performance of the BUK9880-55A is specified by Rth(j-sp) = 15 K/W (junction-to-solder-point), measured with the device soldered to a 1 cm² 2-oz copper pad. This metric reflects real-world PCB heatsinking capability and is more relevant than Rth(j-a) = 120 K/W for designs using thermal vias and copper pour.
Can the BUK9880-55A replace older MOSFETs like the BUK9Y8R5-55B in existing designs?
The BUK9880-55A is not a direct replacement for BUK9Y8R5-55B due to differences in RDS(on) (68–80 mΩ vs. 8.5 mΩ), package (SC-73 vs. LFPAK56), and gate charge. While both are AEC-Q101 55 V N-channel FETs, the BUK9880-55A targets cost-optimized, thermally constrained applications where moderate on-resistance is acceptable.
