Product details
Overview
BSS119E6327 from Infineon Technologies is an N-channel enhancement-mode logic-level SIPMOS™ small-signal MOSFET with 100 V VDS, 6 Ω RDS(on) at VGS = 10 V and ID = 0.17 A, dv/dt rated to 6 kV/µs, and housed in PG-SOT23 package - used for low-power switching in LED drivers, load switches, and level-shifted gate control circuits.
For engineers reviewing the BSS119E6327 datasheet, BSS119E6327 pinout, BSS119E6327 application, or BSS119E6327 equivalent, key selection criteria include logic-level gate drive compatibility (VGS(th) = 1.3–2.3 V), robust dv/dt immunity, low gate charge (Qg = 1.67–2.5 nC), and thermal performance under ambient-limited PCB layouts.
Technical Context
This MOSFET operates in enhancement mode with a threshold voltage range of 1.3–2.3 V, enabling direct interface with 3.3 V and 5 V logic without gate boosting. Its dv/dt rating of 6 kV/µs ensures reliable operation in inductive switching environments where voltage transients occur.
Dynamic parameters include Ciss = 60–78 pF, Coss = 8.6–11.2 pF, and Qgd = 0.76–1.1 nC, supporting fast switching with controlled EMI and low Miller-induced turn-off delay. The integrated body diode has trr = 21.7–32.5 ns and Qrr = 10–15 nC, suitable for non-synchronous flyback and clamp applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - supports input rails up to 80 V DC with margin for transient spikes in industrial and automotive auxiliary supplies. |
| RDS(on) @ VGS = 10 V | 3.4–6 Ω - determines conduction loss at 0.17 A; enables <100 mW dissipation in compact SOT23 footprints. |
| VGS(th) | 1.3–2.3 V - ensures full enhancement with standard 3.3 V microcontroller GPIO, eliminating need for level shifters. |
| Qg | 1.67–2.5 nC - defines gate drive energy requirement; compatible with low-current drivers in space-constrained designs. |
| dv/dt Rating | 6 kV/µs - suppresses false turn-on during high-slew-rate noise events in motor gate drivers or relay snubbers. |
| tr/tf | 3.1–4.6 ns / 27–40 ns - sets minimum PWM frequency capability (~10 MHz max practical) and switching loss profile. |
| Ptot @ TA = 25°C | 0.36 W - limits usable continuous current to ~0.13 A on minimal copper; requires thermal derating above 70°C ambient. |
Pinout & Package
Package: PG-SOT23 (JEDEC TO-236AB), surface-mount, lead-free, tape-and-reel (3000 pcs/reel). Pin 1 = Gate, Pin 2 = Source, Pin 3 = Drain.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Gate) | Control electrode | Receives logic-level voltage; high-impedance input requiring <100 nA leakage; sensitive to ESD. |
| Pin 2 (Source) | Reference node for gate drive and current return | Common connection point for gate driver ground and load return; must be low-inductance in switching paths. |
| Pin 3 (Drain) | High-side or low-side power switch terminal | Carries switched load current; connects to inductive or capacitive loads; exposed drain pad improves thermal path in some variants. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | VGS(th) ≤ 2.3 V enables direct MCU GPIO control without external level-shifting circuitry. |
| dv/dt ruggedness | Rated 6 kV/µs prevents spurious turn-on during fast voltage transients in relay drivers or solenoid controls. |
| Low gate charge | Qg ≤ 2.5 nC reduces switching losses and allows use with low-power gate drivers in battery-powered systems. |
| Integrated body diode | Fast recovery (trr ≤ 32.5 ns) and low VSD (≤ 1.2 V) support freewheeling in non-synchronous DC-DC topologies. |
| Thermal robustness | RthJA = 350 K/W allows operation up to +150°C junction temperature with proper PCB copper area. |
Applications
| LED Constant-Current Driver | Microcontroller Load Switch |
|---|---|
Use Scenario: Driving 1–3 white LEDs from 5–24 V supply using PWM dimming and current regulation via sense resistor feedback. IC Role / Device Role / Timing Role: Low-side switch controlling LED cathode path; modulated at 1–20 kHz to avoid audible noise. Use Value: Logic-level gate ensures full enhancement at 3.3 V MCU output; low RDS(on) minimizes heat rise in sealed enclosures. | Use Scenario: Enabling/disabling peripheral modules (e.g., sensors, radios) in portable IoT devices to reduce standby current. IC Role / Device Role / Timing Role: High-side or low-side power switch activated by GPIO; operated in static ON/OFF states with infrequent transitions. Use Value: Ultra-low IDSS (<0.5 µA at 100 V) prevents leakage-induced battery drain over months of sleep mode. |
| Inductive Load Snubber | Level-Shifted Gate Driver Stage |
Use Scenario: Clamping voltage spikes from relays, solenoids, or small DC motors in industrial control panels. IC Role / Device Role / Timing Role: Fast-switching clamp device placed across coil; triggered only during turn-off transients. Use Value: 6 kV/µs dv/dt rating and fast trr ensure reliable clamping without oscillation or latch-up. | Use Scenario: Level-shifting 3.3 V logic signals to drive higher-voltage MOSFET gates (e.g., 12–24 V half-bridge stages). IC Role / Device Role / Timing Role: Small-signal buffer stage providing isolation and voltage translation between controller and power stage. Use Value: Low Ciss (≤78 pF) and fast td(on) (≤4 ns) preserve signal integrity and timing margins in multi-stage drivers. |
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 |
|---|---|---|---|
| DMN2004LK-7 | RDS(on) = 3.5 Ω @ VGS = 4.5 V; lower VGS(th) (0.5–1.2 V); higher Ciss (105 pF) | Better for 3.3 V-only drive but more susceptible to noise-induced turn-on | Prefer when gate drive is strictly 3.3 V and layout lacks noise filtering. |
| BSS123 | VDS = 100 V; RDS(on) = 6 Ω @ VGS = 10 V; no dv/dt rating specified; higher IDSS (1 µA) | Lacks documented dv/dt immunity; less suitable for inductive snubbing | Select only for static switching where transient immunity is not required. |
Compared with DMN2004LK-7 and BSS123, BSS119E6327 uniquely combines verified 6 kV/µs dv/dt ruggedness, tight VGS(th) distribution, and low Qg, making it optimal for noisy industrial switching where reliability trumps marginal RDS(on) reduction.

FAQ
Is BSS119E6327 suitable for 3.3 V microcontroller GPIO drive without a level shifter?
Yes. With a guaranteed VGS(th) of 1.3–2.3 V and full enhancement at VGS = 4.5 V, the BSS119E6327 delivers RDS(on) ≤ 10 Ω at 3.3 V drive, supporting up to 0.1 A continuous current in thermally optimized layouts. Its low gate leakage (<100 nA) also preserves GPIO drive strength.
What is the maximum safe operating voltage for continuous DC operation?
The absolute maximum VDS is 100 V, but for reliable long-term operation at Tj ≤ 150°C, continuous DC voltage should be limited to ≤80 V to maintain sufficient margin against transients and ensure RDS(on) stability across temperature. Derating is required above 70°C ambient per the Ptot(TA) curve.
Does BSS119E6327 have a qualified automotive grade variant?
No. The BSS119E6327 is rated for industrial temperature range (−55°C to +150°C) and complies with JEDEC standards, but it is not AEC-Q101 qualified. For automotive applications, Infineon offers the BSS119RL variant (AEC-Q101 qualified, same electrical specs, identical PG-SOT23 package).
Can the body diode be used for reverse polarity protection?
No. The integrated body diode conducts forward from source to drain (anode = source, cathode = drain), so it cannot block reverse input voltage. For reverse polarity protection, the device must be placed in series with the positive rail in low-side configuration - but dedicated protection MOSFETs with back-to-back topology or discrete diodes are preferred for this function.
