Product details
Overview
BSS138N from Infineon Technologies is an N-channel enhancement-mode logic-level SIPMOS® small-signal MOSFET rated for 60 V drain-source voltage, 0.23 A continuous drain current at 25 °C, and 3.5 Ω maximum RDS(on) at VGS = 4.5 V. It features dv/dt ruggedness (6 kV/µs), AEC-Q101 qualification, and RoHS/halogen-free compliance, enabling use in automotive body electronics and industrial control signal switching.
For engineers reviewing the BSS138N datasheet, BSS138N pinout, BSS138N application, or BSS138N equivalent, key selection criteria include logic-level gate drive compatibility (VGS(th) = 0.6–1.4 V), low gate charge (Qg = 1.0–1.4 nC), thermal resistance (RthJA = 350 K/W), and reverse diode recovery performance (trr = 9.1–14.5 ns).
Technical Context
This discrete MOSFET operates in enhancement mode with a threshold voltage range of 0.6–1.4 V, ensuring reliable turn-on with standard 3.3 V or 5 V logic outputs. Its dv/dt rating of 6 kV/µs supports robust operation in inductive load switching environments without spurious turn-on.
The device integrates a monolithic body diode with 0.83–1.2 V forward voltage at 0.23 A and 9.1–14.5 ns reverse recovery time, enabling efficient freewheeling in low-power DC-DC converters and LED drivers where fast commutation is required.

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 |
|---|---|---|---|
| DMN2004K-7 | RDS(on) = 2.8 Ω max @ 4.5 V; higher ID = 0.3 A; same SOT-23 package | Slightly lower conduction loss at 0.2 A; identical pinout and drive requirements | Preferred when marginally lower RDS(on) is needed without changing layout |
| 2N7002K | RDS(on) = 5.5 Ω max @ 4.5 V; lower VBR(DSS) = 60 V; AEC-Q101 not specified | Higher conduction loss; lacks automotive qualification and dv/dt rating | Acceptable for cost-sensitive consumer-grade non-automotive designs only |
Compared with DMN2004K-7 and 2N7002K, the BSS138N delivers superior dv/dt immunity and automotive qualification while maintaining competitive RDS(on) and gate charge-making it optimal for safety-critical or transient-heavy 12–24 V systems.

FAQ
Is BSS138N suitable for 3.3 V microcontroller GPIO direct drive?
Yes. With a maximum gate threshold voltage of 1.4 V and guaranteed turn-on at VGS = 3.3 V, the BSS138N fully enhances using standard 3.3 V logic outputs. Its 1.4 nC total gate charge ensures minimal drive strength requirement, eliminating need for buffer stages in most low-frequency switching applications.
What is the maximum safe operating temperature for continuous operation?
The BSS138N supports junction temperatures from –55 °C to +150 °C. At ambient temperatures up to 70 °C, its continuous drain current remains 0.18 A due to thermal derating. With RthJA = 350 K/W and Ptot = 0.36 W at 25 °C, sustained operation above 100 °C ambient requires forced airflow or PCB copper thermal relief.
Does BSS138N include an integrated body diode, and what are its characteristics?
Yes. The BSS138N integrates a monolithic body diode with 0.23 A continuous forward current rating. At 25 °C and 0.23 A, its forward voltage is 0.83–1.2 V, and reverse recovery time is 9.1–14.5 ns under defined test conditions (VR = 30 V, diF/dt = 100 A/µs), supporting efficient freewheeling in low-power DC-DC topologies.
How does the dv/dt rating impact circuit design?
The 6 kV/µs dv/dt rating means the device resists parasitic turn-on during rapid voltage transients-critical when switching inductive loads like relays or solenoids. This eliminates need for external gate snubbers in many 12–24 V automotive and industrial circuits, simplifying layout and improving system robustness against EMI-induced false triggering.
