Product details
Overview
BSS138BKS from Nexperia is a dual N-channel enhancement-mode Trench MOSFET in SOT363 (SC-88) package, rated for 60 V drain-source voltage, 320 mA continuous drain current per transistor, and 1.6 Ω RDS(on) at VGS = 10 V. It serves as a compact, logic-level-compatible low-side load switch or high-speed line driver in space-constrained automotive and industrial control modules.
For engineers reviewing the BSS138BKS datasheet, BSS138BKS pinout, BSS138BKS application, or BSS138BKS equivalent, this device is selected for dual-channel switching where fast turn-on/turn-off (5–76 ns propagation delays), AEC-Q101 qualification, and 1.5 kV HBM ESD protection are required in FR4 PCB-mounted designs.
Technical Context
This dual discrete MOSFET integrates two independent N-channel channels in a single 6-pin TSSOP package, sharing no internal connection between transistors. Each channel features trench-gate architecture enabling low gate charge (0.6–0.7 nC total) and high transconductance (700 mS typical).
It operates with gate threshold voltage ranging from 0.48 V to 1.6 V, supports logic-level drive down to 2.5 V (RDS(on) ≤ 6.5 Ω at 10 mA), and maintains stable on-resistance up to 150 °C junction temperature (RDS(on) ≤ 3.2 Ω at VGS = 10 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum blocking voltage per channel; suitable for 24 V automotive supply rails with margin. |
| ID (continuous) | 320 mA per transistor - Supports moderate-current loads such as LED strings or sensor biasing without heatsinking. |
| RDS(on) | 1.0 Ω typical at VGS = 10 V - Enables <100 mW conduction loss at 320 mA, critical for thermally constrained layouts. |
| QG(tot) | 0.6 nC typical - Low gate charge allows fast switching with minimal driver strength (e.g., GPIO-driven). |
| VGS(th) | 0.48–1.6 V - Ensures reliable turn-on with 1.8 V/3.3 V/5 V logic families without level-shifting. |
| ESD rating | 1.5 kV HBM - Provides robust handling during board assembly and field operation in unshielded environments. |
| Tj max | 150 °C - Rated for under-hood automotive applications per AEC-Q101 stress qualification. |
Pinout & Package
SOT363 (SC-88/TSSOP6) plastic surface-mount package: 2.2 mm × 1.8 mm footprint, 0.65 mm pitch, 1.15 mm height, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Source of TR1 | Low-side return path for first transistor; tied to ground plane in load-switch configuration. |
| 2 | Gate of TR1 | Logic-level input controlling TR1; requires <0.7 nC charge for full turn-on. |
| 3 | Drain of TR2 | High-side output node for second transistor; connects to load or signal line. |
| 4 | Source of TR2 | Independent ground reference for TR2; electrically isolated from Pin 1. |
| 5 | Gate of TR2 | Separate logic input for TR2; enables independent dual-channel control. |
| 6 | Drain of TR1 | Primary switched output for TR1; shares thermal pad with Pin 3 for power dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level compatibility | Operates fully enhanced at VGS ≥ 2.5 V, eliminating need for gate drivers in 3.3 V microcontroller interfaces. |
| Fast switching | Turn-on delay <10 ns and fall time <20 ns enable >10 MHz PWM operation in digital signal routing. |
| Trench MOSFET technology | Delivers lower RDS(on) and higher gfs than planar equivalents, improving efficiency in battery-powered systems. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTGB, and ESD stress per JESD22-A114. |
| ESD protection | 1.5 kV HBM rating reduces risk of assembly damage and field failures in handheld or exposed I/O modules. |
Applications
| Relay Driver | High-Speed Line Driver |
|---|---|
Use Scenario: Driving coil of 12 V automotive relay in body control module with MCU GPIO. IC Role / Device Role / Timing Role: Dual-channel low-side switch replacing discrete transistors; one channel controls relay, other handles status LED. Use Value: Eliminates external base resistors and flyback diodes; 60 V rating withstands relay coil flyback spikes without clamping. | Use Scenario: Transmitting TTL-level signals across noisy industrial backplanes with 50 cm trace length. IC Role / Device Role / Timing Role: Active buffer stage isolating MCU pins from capacitive bus loading and EMI coupling. Use Value: Sub-10 ns propagation ensures signal integrity at 20 Mbps data rates; dual layout minimizes inter-channel skew. |
| Low-Side Load Switch | Switching Circuit |
Use Scenario: Power gating of 5 V sensor sub-circuit in ADAS camera ECU to reduce standby current. IC Role / Device Role / Timing Role: Controlled power path switch with independent enable for two sensor groups. Use Value: 320 mA per channel supports multiple sensors; 1.0 Ω RDS(on) limits voltage drop to <320 mV at full load. | Use Scenario: Configurable logic-level translator and polarity inverter in programmable I/O expander interface. IC Role / Device Role / Timing Role: Dual inverting switch implementing NAND/NOR functions via external pull-ups. Use Value: Fast 20 ns fall time enables clean edge generation for clock distribution; dual topology saves board area vs. two SOT23 devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2041LSD-13 | Single-channel SOT23-6; 20 V VDS, 4.2 A ID, 29 mΩ RDS(on) | Higher current, lower voltage; not AEC-Q101 qualified | Select only for non-automotive 3.3 V logic-switching where higher current and lower RDS(on) outweigh dual-channel need. |
| FDMA1023NZ | Dual N-channel SOT-363; 20 V VDS, 2.8 A ID, 42 mΩ RDS(on); no AEC-Q101 | Higher current density but half the voltage rating; lacks automotive qualification | Prefer for consumer USB-C PD load switching where 20 V compliance suffices and thermal budget permits smaller RDS(on). |
Compared with BSS138BKS, DMN2041LSD-13 offers higher current capacity but sacrifices dual-channel integration and automotive qualification, while FDMA1023NZ provides lower on-resistance at reduced voltage rating and no AEC-Q101 validation-making BSS138BKS uniquely suited for dual, 60 V, AEC-Q101-compliant switching in space-limited automotive modules.

FAQ
What is the maximum continuous drain current per channel at 100 °C ambient temperature?
At Tamb = 100 °C, the maximum continuous drain current per transistor is 210 mA, as specified in the Limiting Values table under conditions VGS = 10 V and single-sided FR4 PCB mounting. This derating accounts for thermal resistance and junction temperature limits up to 150 °C.
Can BSS138BKS be used with 1.8 V logic-level microcontrollers?
Yes - its gate threshold voltage range (0.48–1.6 V) and confirmed RDS(on) of ≤6.5 Ω at VGS = 2.5 V and ID = 10 mA allow functional enhancement with 1.8 V logic, though full 320 mA capability requires ≥4.5 V gate drive per the Characteristics table.
Is the SOT363 package lead-free and RoHS compliant?
Yes - the BSS138BKS uses a lead-free, halogen-free, and RoHS-compliant SOT363 (TSSOP6) package, verified per Nexperia's product compliance documentation and JEDEC standard J-STD-020 moisture sensitivity level (MSL) 1 rating.
How does the dual-channel isolation benefit PCB layout?
The two transistors share no internal connection: Pins 1/2/6 form TR1 (S1/G1/D1), Pins 3/4/5 form TR2 (D2/S2/G2). This enables independent grounding, separate thermal pads, and noise-isolated routing - critical for mixed-signal systems where one channel drives noisy loads while the other handles sensitive analog circuitry.
