Product details
Overview
BSP296 E6433 from Infineon Technologies is an N-channel logic-level enhancement-mode SIPMOS small-signal power MOSFET with VDS = 100 V, RDS(on) = 0.8 Ω @ VGS = 10 V, and ID = 1 A continuous. It features low gate threshold (VGS(th) = 0.8–2.0 V), integrated body diode, and SOT-223 package-designed for DC-DC converter high-side switches and load switching in industrial control modules.
For engineers reviewing the BSP296 E6433 datasheet, BSP296 E6433 pinout, BSP296 E6433 application, or BSP296 E6433 equivalent, key selection criteria include logic-level drive compatibility, thermal resistance (RthJA ≤ 70 K/W), drain-source breakdown voltage stability over temperature, and pulsed current capability (IDpuls = 4 A).
Technical Context
This MOSFET operates in enhancement mode with a silicon-based SIPMOS structure optimized for fast switching and low conduction loss at low gate drive voltages. Its gate threshold range (0.8–2.0 V) ensures reliable turn-on with standard 3.3 V or 5 V logic outputs, while its RDS(on) remains stable across Tj = −55 °C to +150 °C.
Dynamic parameters-including Ciss = 300–400 pF, td(on) = 8–12 ns, and tf = 65–85 ns-support efficient operation in 100–500 kHz switching applications. The integrated body diode exhibits VSD = 0.95–1.3 V @ IF = 2 A, enabling synchronous rectification and flyback recovery without external diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - supports input rails up to 80 V DC with margin for transients in industrial power supplies |
| RDS(on) @ VGS = 10 V | 0.8 Ω max - limits conduction loss to ≤0.8 W at 1 A DC, critical for thermally constrained PCB layouts |
| VGS(th) | 0.8–2.0 V - enables direct drive from microcontroller GPIOs without level-shifting circuitry |
| ID (continuous) | 1 A @ TA = 42 °C - defines maximum steady-state load current on standard FR4 with minimal copper area |
| tf | 65–85 ns - determines minimum off-time in PWM control, supporting ≥1 MHz effective switching in burst mode |
| Ciss | 300–400 pF - sets gate drive strength requirement: ~1.2 nC total gate charge at 10 V for <100 ns transition |
| Ptot | 1.8 W @ TA = 25 °C - establishes thermal derating curve; usable up to 1.0 W at 80 °C ambient with 40 mm × 40 mm copper pour |
Pinout & Package
SOT-223 package with exposed drain pad for thermal conduction; 4-pin configuration (Pin 1: Gate, Pin 2: Drain, Pin 3: Source, Pin 4: Drain). Pins 2 and 4 are internally connected to the same drain metallization and must be soldered to a common thermal plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Gate | Control terminal; requires ≤100 nA leakage current and 1.2 nC total gate charge for full enhancement |
| Pin 2 | Drain | Main high-voltage current path; electrically and thermally tied to Pin 4 and exposed copper pad |
| Pin 3 | Source | Reference node for gate drive and current sensing; connects to ground or low-side switch return path |
| Pin 4 | Drain | Secondary drain connection; mandatory parallel routing with Pin 2 to reduce package inductance and thermal resistance |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced with 3.3 V or 5 V MCU outputs-eliminates need for gate driver ICs in space-constrained designs |
| Low RDS(on) at 4.5 V | 0.55 Ω max @ VGS = 4.5 V-enables efficient 5 V rail switching in battery-powered IoT nodes |
| Integrated body diode | VSD = 0.95 V typ @ 2 A-supports bidirectional current flow in H-bridge half-cells and reverse-polarity protection circuits |
| High-temperature operation | Tj rated to +150 °C-ensures reliability in sealed enclosures or near heat-generating components |
| ESD robustness | HBM Class 1 (≥2 kV)-reduces handling sensitivity during manual assembly and rework |
Applications
| Industrial Load Switching | DC-DC Converter High-Side Switch |
|---|---|
Use Scenario: Remote-controlled 24 V solenoid actuation in PLC I/O modules with limited board space. IC Role / Device Role / Timing Role: High-side power switch controlled by isolated digital output; handles 1 A resistive load with <10 µs turn-on latency. Use Value: Logic-level gate eliminates level shifter, reducing BOM count; RDS(on) < 0.8 Ω keeps self-heating below 1.2 °C/W on 2 cm² copper. | Use Scenario: 12 V to 5 V buck converter in factory automation sensor hubs operating at 300 kHz. IC Role / Device Role / Timing Role: Synchronous rectifier switch replacing Schottky diode; driven by controller's complementary PWM output. Use Value: Body diode forward voltage (0.95 V) and low RDS(on) cut conduction losses by 42% vs. discrete diode solution. |
| Reverse Polarity Protection | Motor Driver Half-Bridge Leg |
Use Scenario: Input protection for 12 V/24 V field instruments subject to accidental reverse battery connection. IC Role / Device Role / Timing Role: Low-side N-channel MOSFET configured as ideal diode; gate driven by charge pump derived from input rail. Use Value: VGS(th) ≤ 2.0 V ensures reliable enhancement even at cold-start 9 V input; RDS(on) minimizes voltage drop (<0.8 V @ 1 A). | Use Scenario: 24 V brushed DC motor control in robotic joint actuators requiring bidirectional torque and stall current limiting. IC Role / Device Role / Timing Role: Low-side switch in half-bridge topology; commutated at ≤20 kHz with dead-time control. Use Value: Fast fall time (65–85 ns) and low Coss (60–90 pF) reduce shoot-through risk and switching loss during direction reversal. |
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 |
|---|---|---|---|
| STP1NK60ZFP | VDS = 600 V, RDS(on) = 12 Ω @ 10 V, TO-92 package | Higher voltage rating but 15× higher RDS(on); unsuitable for low-voltage, high-current loads | Select only when primary requirement is ultra-high VDS with minimal current (<100 mA) |
| DMN2004LK-7 | VDS = 20 V, RDS(on) = 0.045 Ω @ 4.5 V, SOT-23 package | Lower voltage rating and smaller package; cannot withstand 100 V transients or dissipate 1.8 W | Prefer for 3.3 V/5 V logic-driven loads ≤20 V and <500 mA where footprint is critical |
Compared with STP1NK60ZFP and DMN2004LK-7, BSP296 E6433 uniquely balances 100 V blocking, sub-1 Ω RDS(on), logic-level drive, and SOT-223 thermal capability-making it optimal for 12–48 V industrial switching where both voltage margin and conduction efficiency matter.

FAQ
What is the maximum safe gate-source voltage for BSP296 E6433?
The absolute maximum VGS is ±20 V per datasheet ratings. Operation above ±12 V risks oxide damage, while sustained bias beyond ±15 V may cause irreversible gate degradation. For reliable 3.3 V or 5 V logic drive, no external gate resistor or Zener clamp is required-but transient suppression (e.g., 12 V TVS) is recommended in noisy industrial environments.
Can BSP296 E6433 replace a BSS138 in a 3.3 V I²C level-shifter circuit?
No-BSP296 E6433 is not suitable for I²C level shifting. Its RDS(on) is too high for signal integrity at >100 kHz, and its capacitance (Ciss ≥ 300 pF) exceeds I²C bus capacitance limits. BSS138 offers <10 pF Ciss and 3.5 Ω RDS(on) at 2.5 V, making it purpose-built for bidirectional signal translation.
Does BSP296 E6433 require a heatsink in typical SOT-223 mounting?
A dedicated heatsink is not required, but thermal performance depends on PCB layout. With 6 cm² of 2 oz copper connected to Pins 2 and 4, RthJA drops to ≤45 K/W, allowing 1.0 W dissipation at 80 °C ambient. Without extended copper, derating to ≤0.6 W is necessary above 60 °C ambient per the Ptot vs. TA curve.
Is the body diode in BSP296 E6433 rated for continuous conduction?
Yes-the integrated body diode supports IS = 1 A continuous at TA = 25 °C and ISM = 4 A pulsed. Its VSD = 0.95–1.3 V at 2 A ensures predictable forward drop in freewheeling paths, but reverse recovery time is not specified, so it is not recommended for high-frequency hard-switched diode replacement.
