Product details
Overview
BSS138NL6327HTSA1 from Infineon Technologies is an N-channel enhancement-mode logic-level SIPMOS® small-signal MOSFET rated for 60 V VDS, 0.23 A continuous drain current, and 3.5 Ω max RDS(on) at VGS = 4.5 V. It features dv/dt ruggedness (6 kV/µs), AEC-Q101 qualification, and RoHS/halogen-free compliance - deployed in automotive body control modules, LED load switching, and low-power level-shifting interfaces.
For engineers reviewing the BSS138NL6327HTSA1 datasheet, BSS138NL6327HTSA1 pinout, BSS138NL6327HTSA1 application, or BSS138NL6327HTSA1 equivalent, key selection criteria include logic-level gate drive compatibility (VGS(th) = 0.6–1.4 V), thermal resistance (RthJA = 350 K/W), reverse diode recovery performance (trr = 9.1–14.5 ns), and SOT-23 footprint constraints.
Technical Context
This discrete MOSFET operates in enhancement mode with a threshold voltage range of 0.6–1.4 V at ID = 26 µA, enabling direct interfacing with 3.3 V and 5 V logic controllers. Its dv/dt rating of 6 kV/µs ensures robustness against voltage transients in inductive load switching.
Dynamic parameters include Ciss = 32–41 pF, Coss = 7.2–9.5 pF, and Qg = 1.0–1.4 nC, supporting fast switching in low-power DC-DC bias rails and signal routing applications where gate drive energy and Miller effect are design-critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS max | 60 V - supports 24 V automotive and industrial bus systems with margin |
| RDS(on) max | 3.5 Ω @ VGS = 4.5 V - enables <100 mW conduction loss at 0.19 A |
| ID cont | 0.23 A @ TA = 25 °C - suitable for low-current loads like sensor biasing or LED indicators |
| VGS(th) | 0.6–1.4 V - guarantees turn-on with standard 3.3 V GPIO without level shifters |
| trr | 9.1–14.5 ns - minimizes switching losses in 1–10 MHz PWM-controlled loads |
| RthJA | 350 K/W - requires minimal PCB copper area for thermal management in SOT-23 |
| Qg | 1.0–1.4 nC - allows efficient driving with low-power microcontroller outputs |
Pinout & Package
Package: PG-SOT-23 (JEDEC TO-236AB), surface-mount, 3-pin plastic package with standard footprint per Infineon outline document Rev. 2.86.
| Pin/Terminal | Circuit Role | Design Meaning |

| 3 (Drain) | Load connection | Connects to switched load (e.g., LED anode or relay coil); carries full load current and withstands VDS stress |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive Interior Lighting | Low-Power Sensor Biasing |
|---|---|
Use Scenario: Switching 12 V LED strips in door handle illumination and map lights. IC Role / Device Role / Timing Role: Low-side load switch controlling current path to LEDs with PWM dimming capability. Use Value: Logic-level gate enables direct MCU PWM output drive; low RDS(on) limits self-heating under continuous 0.2 A operation. | Use Scenario: Providing stable bias current to analog temperature or pressure sensors. IC Role / Device Role / Timing Role: Precision current source switch enabling sensor power gating during sleep modes. Use Value: Tight VGS(th) distribution (0.6–1.4 V) ensures consistent turn-on across temperature; low leakage (<0.1 µA @ 60 V) preserves battery life. |
| USB Port Power Control | Level-Shifting Interface |
Use Scenario: Enabling/disabling 5 V VBUS to downstream USB peripherals in embedded hosts. IC Role / Device Role / Timing Role: High-side or low-side power switch managing hot-plug sequencing and overcurrent isolation. Use Value: Fast tr/tf (3–4.5 ns / 8.2–12.3 ns) supports clean power ramp-up; AEC-Q101 grade adds reliability for industrial USB hubs. | Use Scenario: Translating 1.8 V I²C signals to 3.3 V domains in mixed-voltage SoC subsystems. IC Role / Device Role / Timing Role: Bidirectional level shifter using back-to-back configuration with integrated body diodes. Use Value: Low Ciss (32–41 pF) and fast trr (9.1–14.5 ns) preserve signal integrity up to 400 kHz I²C speeds. |
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 @ VGS = 4.5 V; higher ID = 0.3 A; same SOT-23 package | Better conduction efficiency at >0.2 A but slightly higher gate charge (1.6 nC) | Preferred when lower on-resistance is critical and gate drive strength permits higher Qg |
| NX138N,115 | VGS(th) = 0.5–1.2 V; RDS(on) = 3.8 Ω max @ 4.5 V; Nexperia AEC-Q101 qualified | Broader VGS(th) distribution may require stronger gate drive margining | Selected for supply chain diversification where identical functional specs and qualification are required |
Compared with DMN2004K-7 and NX138N,115, BSS138NL6327HTSA1 offers tighter VGS(th) control and lower Qg, making it optimal for weak-drive microcontrollers and thermally constrained PCB layouts despite marginally higher RDS(on).

FAQ
Is BSS138NL6327HTSA1 suitable for high-frequency PWM switching?
Yes - with tr = 3.0–4.5 ns and tf = 8.2–12.3 ns, plus low Ciss (32–41 pF) and Qg (1.0–1.4 nC), it supports clean switching up to 10 MHz in low-duty-cycle applications such as LED dimming and sensor gating, provided gate drive impedance is ≤50 Ω.
What is the maximum safe operating voltage for BSS138NL6327HTSA1 in automotive 12 V systems?
The device is rated for VDS = 60 V, providing 5× margin over nominal 12 V automotive systems and full coverage of load-dump transients (up to 40 V per ISO 7637-2 Pulse 5a). Derating is not required below 48 V DC, and dv/dt immunity (6 kV/µs) prevents spurious turn-on during fast spikes.
Does BSS138NL6327HTSA1 include an integrated body diode, and is it usable in bidirectional configurations?
Yes - it features a monolithic parasitic body diode with IS = 0.23 A continuous and trr = 9.1–14.5 ns. This diode is fully characterized and usable in level-shifting and flyback paths, though its VSD = 0.83–1.2 V at 0.23 A implies moderate forward loss in sustained conduction.
How does the AEC-Q101 qualification impact design validation for industrial applications?
AEC-Q101 qualification confirms stress testing across temperature cycling, HTRB, HAST, and ESD (Class 0), exceeding standard industrial reliability requirements. While not mandatory for non-automotive use, it provides proven field reliability for harsh environments - e.g., extended temperature operation (-55 to 150 °C) and vibration-prone enclosures - reducing qualification effort.
