Product details
Overview
BSS87 E6433 from Infineon Technologies is an N-channel enhancement-mode logic-level SIPMOS small-signal transistor in SOT-89 package, rated for 240 V drain-source breakdown voltage, 0.26 A continuous drain current at 25°C, and 3.9–6 Ω RDS(on) at VGS = 10 V. It is AEC-Q101 qualified and dv/dt rated (6 kV/µs), suited for high-reliability automotive load switching and industrial power control.
For engineers reviewing the BSS87 E6433 datasheet, BSS87 E6433 pinout, BSS87 E6433 application, or BSS87 E6433 equivalent, key selection criteria include logic-level gate drive compatibility (VGS(th) = 0.8–1.8 V), robust dv/dt immunity, low gate charge (Qg = 3.7–5.5 nC), and halogen-free RoHS-compliant construction.
Technical Context
This device operates as a single N-channel MOSFET with enhancement-mode behavior, requiring positive gate bias relative to source to conduct. Its logic-level threshold (VGS(th) typ. 1.2 V) enables direct drive from 3.3 V or 5 V microcontrollers without level-shifting circuitry.
The 6 kV/µs dv/dt rating ensures reliable operation in inductive switching environments-such as automotive solenoid drivers-without false turn-on. Thermal resistance RthJA is 70 K/W on 6 cm² PCB copper, supporting stable 0.21 A operation at 70°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS max | 240 V - supports 24 V automotive systems with ≥10× safety margin against transients |
| RDS(on) @ 10 V | 3.9–6 Ω - enables <150 mW conduction loss at 0.26 A, suitable for low-power switching |
| ID cont @ 25°C | 0.26 A - sufficient for LED drivers, relay coils, and sensor interface loads |
| VGS(th) | 0.8–1.8 V - ensures turn-on with standard logic outputs; no external gate driver needed |
| Qg | 3.7–5.5 nC - allows fast switching with low gate-drive power, reducing dynamic losses |
| dv/dt rating | 6 kV/µs - prevents spurious turn-on during high-slew-rate inductive flyback events |
| Tj range | −55 to +150°C - meets extended temperature requirements for under-hood automotive use |
Pinout & Package
Package: SOT-89-4-2 (3-pin variant with exposed drain tab), Pb-free, tape-and-reel (1000 pcs/reel). Pin 2 is drain-connected tab for thermal and electrical connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Reference node for gate drive; connects to system ground or low-side return path |
| Pin 2 (Drain) | Drain terminal / thermal pad | Main current output path; soldered to PCB copper area for heat dissipation (RthJA = 70 K/W) |
| Pin 3 (Gate) | Control input | High-impedance MOSFET gate; accepts logic-level signals directly from MCU GPIO |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensors |
| Logic-level gate drive | VGS(th) ≤ 1.8 V enables direct interfacing with 3.3 V/5 V microcontrollers and ASICs |
| Halogen-free & RoHS | Complies with IEC61249-2-21 and EU RoHS Directive (Pb-free plating, no Br/Sb) |
| dv/dt rated | 6 kV/µs immunity eliminates need for external snubbers in inductive load switching |
| Low Qgd/Qg ratio | Qgd = 1.7–2.5 nC / Qg = 3.7–5.5 nC improves switching stability and reduces Miller-induced oscillation risk |
Applications
| Automotive Solenoid Driver | Industrial Sensor Interface |
|---|---|
Use Scenario: Driving 24 V fuel injector or HVAC actuator solenoids in engine control units. IC Role / Device Role / Timing Role: High-side or low-side switch controlling coil current with precise on/off timing. Use Value: AEC-Q101 qualification and 6 kV/µs dv/dt rating prevent false triggering during cranking transients. | Use Scenario: Isolating and switching analog sensor supply rails (e.g., pressure, temperature) in PLC modules. IC Role / Device Role / Timing Role: Load switch enabling/disabling sensor power to reduce standby current. Use Value: Logic-level gate drive allows direct MCU control; low RDS(on) minimizes voltage drop across supply path. |
| LED Lighting Control | Power Sequencing in Embedded Systems |
Use Scenario: Dimmable LED string switching in automotive interior lighting or industrial status indicators. IC Role / Device Role / Timing Role: Low-duty-cycle PWM-controlled current path for brightness regulation. Use Value: Fast switching (tr/tf ≤ 5.2/41 ns) and low Qg support clean PWM edges up to 100 kHz. | Use Scenario: Controlled power-up sequencing of multiple voltage rails in medical or test equipment. IC Role / Device Role / Timing Role: Independent enable switch for auxiliary 3.3 V or 5 V subsystems. Use Value: Tight VGS(th) distribution (0.8–1.8 V) ensures consistent turn-on timing across production lots. |
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 |
|---|---|---|---|
| BSS138W E6327 | Lower VDS (50 V), higher RDS(on) (3.5 Ω @ 10 V), lower ID (0.22 A) | Not suitable for 24 V automotive loads; limited to 5 V signal-path switching | Select only for low-voltage digital isolation where 240 V rating is unnecessary |
| DMN2004LK-7 | Higher ID (0.55 A), same VDS (200 V), slightly higher VGS(th) (1–2.5 V) | Requires marginally higher gate drive; better for higher-current solenoids | Prefer when >0.3 A continuous load current is required and board space permits larger SOT-23-3 footprint |
Compared with BSS87 E6433, BSS138W offers smaller size but insufficient voltage headroom for automotive 24 V systems, while DMN2004LK provides higher current capability at the cost of less precise logic-level compatibility and larger package.

FAQ
Is BSS87 E6433 suitable for high-side switching configurations?
Yes-BSS87 E6433 supports high-side switching when used with appropriate gate-driving circuitry that provides VGS ≥ 10 V relative to the source. Its 240 V VDS rating and 6 kV/µs dv/dt immunity make it viable for 24 V automotive high-side loads, though external level-shifting may be needed if driving from ground-referenced logic.
What is the maximum safe operating temperature for continuous operation?
The junction temperature must not exceed +150°C. At TA = 70°C with minimum PCB footprint, continuous drain current is derated to 0.21 A. With 6 cm² copper cooling area, full 0.26 A is supported up to 25°C ambient; thermal design must maintain Tj ≤ 150°C under worst-case power dissipation.
Does BSS87 E6433 include an integrated body diode, and what are its characteristics?
Yes-it features an inherent reverse recovery diode with 0.26 A continuous forward current rating, 0.82–1.2 V forward voltage at IF = 0.26 A, and trr = 53.6–80.4 ns. This diode supports freewheeling in inductive loads but is not optimized for high-frequency synchronous rectification.
Can BSS87 E6433 replace BSS84 in existing designs?
No-BSS84 is a P-channel device (−50 V, −130 mA), while BSS87 E6433 is N-channel (240 V, 0.26 A). They differ in polarity, voltage rating, current capability, and gate threshold. Direct replacement would require circuit topology changes, including inversion of control logic and power rail referencing.
