Product details
Overview
BSP320S E6433 from Infineon Technologies is a P-channel enhancement-mode MOSFET in SOT-223 package, rated for −60 V VDS, −3.5 A ID (TC = 25 °C), and RDS(on) ≤ 1.4 Ω at VGS = −10 V. It serves as a low-side load switch in automotive body electronics, industrial power management, and LED lighting control circuits.
For engineers reviewing the BSP320S E6433 datasheet, BSP320S E6433 pinout, BSP320S E6433 application, or BSP320S E6433 equivalent, key selection criteria include guaranteed RDS(on) at −10 V gate drive, specified avalanche energy rating (EAS = 75 mJ), and AEC-Q101 qualification for automotive use.
Technical Context
This discrete MOSFET operates in enhancement mode with gate threshold voltage VGS(th) between −1 V and −3 V, enabling reliable turn-on with standard logic-level negative gate drive. Its SOA is characterized up to TC = 100 °C with pulse-width-limited safe operating area curves defined per JEDEC JESD82-1.
The device features an integrated body diode with reverse recovery time trr = 45 ns and Qrr = 29 nC at IF = −3.5 A, supporting moderate-frequency switching in DC-DC and load-switching topologies without external snubbing.

Applications
| Automotive Body Control Module | Industrial LED Driver |
|---|---|
Use Scenario: Switching 12 V incandescent and LED loads (e.g., interior lamps, door locks) in centralized BCM units. IC Role / Device Role / Timing Role: Low-side load switch controlling current path to ground; driven by 3.3 V/5 V microcontroller with level-shifting or direct −10 V gate bias. Use Value: Eliminates need for external flyback diodes due to specified body diode recovery performance and 75 mJ avalanche rating. |

IC Role / Device Role / Timing Role: PWM-controlled current sink switch operating at 1–10 kHz; placed between LED cathode and ground. Use Value: RDS(on) ≤ 1.4 Ω ensures <1.7 W conduction loss at 3.5 A, reducing heatsink requirements in enclosed fixtures. |
| Smart Power Outlet | 12 V DC Power Distribution Unit |
Use Scenario: Remote-controllable AC/DC outlet with overcurrent and short-circuit protection. IC Role / Device Role / Timing Role: Primary load switch in eFuse-like architecture; coordinated with current-sense amplifier and comparator.

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP3PF50 | VDS = −50 V, RDS(on) = 1.8 Ω @ −10 V, non-AEC-Q101 | Limited to industrial/non-automotive use; lower voltage rating restricts 24 V system compatibility | Select when cost sensitivity outweighs automotive qualification and 60 V margin |
| IRF9540NPBF | VDS = −100 V, RDS(on) = 200 mΩ @ −10 V, TO-220 package | Higher voltage headroom but larger footprint and higher gate charge (Qg = 54 nC) | Prefer for 48 V systems requiring >60 V blocking, accepting trade-off in board space and drive complexity |
Compared with STP3PF50 and IRF9540NPBF, BSP320S E6433 uniquely balances AEC-Q101 compliance, 60 V rating, compact SOT-223 footprint, and low gate charge-making it optimal for space-constrained automotive and industrial load-switch designs where reliability and thermal efficiency are prioritized.

FAQ
Is BSP320S E6433 suitable for 24 V automotive systems?
Yes. With a −60 V VDS rating and AEC-Q101 qualification, BSP320S E6433 supports 24 V nominal systems including load-dump transients up to ±60 V. Its avalanche energy rating (EAS = 75 mJ) ensures survivability during inductive switching events common in solenoid and relay control.
What is the maximum junction temperature for continuous operation?
The absolute maximum junction temperature is 150 °C. For continuous DC operation at ID = −3.5 A, thermal design must maintain TJ ≤ 150 °C using the SOT-223 package's RthJC = 50 K/W and appropriate PCB copper area. Derating is required above TC = 25 °C per the datasheet SOA curve.
Does BSP320S E6433 require a gate resistor for PWM switching?
A gate resistor (typically 10–47 Ω) is recommended to dampen ringing and limit peak gate current during 1–10 kHz PWM operation. The device's Qg = 11 nC allows clean switching with standard logic drivers, but uncontrolled gate drive may cause oscillation due to PCB trace inductance interacting with Ciss = 340 pF.
Can BSP320S E6433 replace BSP317 in existing designs?
No. BSP317 is an N-channel MOSFET (VDS = 60 V, ID = 2.2 A), requiring high-side or level-shifted gate drive. BSP320S E6433 is P-channel and intended for low-side switching. Direct replacement would invert control logic and compromise safety; redesign of gate drive and layout is required.
