Product details
Overview
BSP320S E6327 from Infineon Technologies is a P-channel enhancement-mode MOSFET in SOT-223 package, rated for -60 V VDS, -2.5 A continuous drain current, and 2.5 Ω RDS(on) at VGS = −10 V. It serves as a low-side load switch in automotive body electronics and industrial power management circuits requiring robust reverse-battery protection.
For engineers reviewing the BSP320S E6327 datasheet, BSP320S E6327 pinout, BSP320S E6327 application, or BSP320S E6327 equivalent, key selection criteria include its guaranteed RDS(on) at −4.5 V gate drive, AEC-Q101 qualification, thermal resistance (RthJA = 80 K/W), and SOA compliance up to Tj = 150 °C.
Technical Context
This discrete MOSFET operates in enhancement mode with threshold voltage VGS(th) between −1 V and −2.5 V, enabling reliable turn-on with standard logic-level gate drivers. Its integrated body diode exhibits 45 ns reverse recovery time (trr) and 1.2 A peak forward current rating.
The device uses trench-stop technology for optimized conduction and switching trade-offs, supporting pulsed drain currents up to −5 A and featuring 100% avalanche-rated ruggedness per UIS test (EAS = 45 mJ at Tj = 25 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VDS | −60 V - Maximum blocking voltage for reverse-battery and load-dump tolerant designs |
| ID (continuous) | −2.5 A @ TA = 25 °C - Sustained load switching capability without heatsink in ambient airflow |
| RDS(on) | 2.5 Ω @ VGS = −10 V; 3.5 Ω @ VGS = −4.5 V - Enables direct interface with 5 V microcontrollers |
| VGS(th) | −1.0 to −2.5 V - Ensures predictable turn-on with low-voltage control signals |
| EAS | 45 mJ @ Tj = 25 °C - Confirmed single-pulse avalanche energy for inductive load snubbing |
| RthJA | 80 K/W - Thermal performance baseline for PCB layout with 1 cm² copper pour |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control input | Accepts negative gate-source voltage to enable conduction; requires <10 nF gate capacitance for <100 ns switching |
| 2 (Source) | Reference node | Connected to system ground or battery positive in high-side configurations; defines VGS reference |
| 3 (Drain) | Power output | High-current path to load; soldered to PCB copper for thermal dissipation and low-inductance routing |
| 4 (Tab/Drain) | Thermal & electrical connection | Exposed metal tab electrically tied to Drain; must be soldered to ≥1 cm² thermal pad for RthJA compliance |
Key Features

| Low gate charge (QG) | 10 nC @ VGS = −10 V - Reduces driver power loss and enables 1 MHz PWM operation |
| Fast body diode | trr = 45 ns - Minimizes commutation losses in synchronous rectifier and H-bridge freewheeling |
Applications
| Automotive Door Module | Industrial PLC Output Stage |
|---|---|
Use Scenario: Controlling mirror heaters, window lift motors, and interior lighting via LIN-connected ECUs. IC Role / Device Role / Timing Role: Low-side power switch enabling PWM dimming and fault-isolated load control. Use Value: AEC-Q101 qualification ensures reliability across 15-year vehicle lifetime; RDS(on) stability over temperature avoids thermal runaway during repeated actuation. |
Use Scenario: Driving solenoids, relays, and indicator LEDs in DIN-rail mounted programmable logic controllers. IC Role / Device Role / Timing Role: Solid-state replacement for electromechanical relays in 24 V DC output modules. Use Value: 2.5 Ω RDS(on) at −4.5 V allows direct drive from PLC's 5 V logic outputs, eliminating level-shifter ICs and reducing BOM count. |
| Reverse-Battery Protection | DC Power Distribution Unit |
Use Scenario: Preventing damage to 12 V subsystems during jump-start misconnections or battery polarity reversal. IC Role / Device Role / Timing Role: P-channel MOSFET configured as ideal diode in series with main power rail. Use Value: 60 V rating exceeds ISO 7637-2 pulse 5a (−100 V/50 ms); low RDS(on) limits voltage drop to <60 mV at 2.5 A, minimizing heat generation. |
Use Scenario: Modular 12 V/24 V power distribution boards for robotics and factory automation equipment. IC Role / Device Role / Timing Role: Individual channel switch enabling remote on/off and current-limited startup sequencing. Use Value: Integrated avalanche ruggedness eliminates need for external TVS clamps; SOA compliance supports hot-plug insertion without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN601WK-7 | RDS(on) = 3.0 Ω @ −4.5 V; no AEC-Q101 qualification; RthJA = 90 K/W | Targeted at industrial consumer-grade power switches, not automotive environments | Lower cost where automotive qualification and thermal margin are non-critical |
| IPD600P06L3GATMA1 | RDS(on) = 2.2 Ω @ −4.5 V; TO-252 package; higher ID = −4.5 A; AEC-Q101 qualified | Requires larger footprint and different thermal layout; better suited for higher-current loads | Preferred when >3 A continuous current or lower RDS(on) at −4.5 V is required |
Compared with DMN601WK-7 and IPD600P06L3GATMA1, the BSP320S E6327 uniquely balances AEC-Q101 compliance, SOT-223 compactness, and −4.5 V gate drive capability-making it optimal for space-constrained automotive body control units where thermal budget and qualification are jointly critical.

FAQ
What is the maximum safe operating temperature for BSP320S E6327?
The absolute maximum junction temperature is 150 °C. Derating begins at Tj = 125 °C, where continuous drain current drops to −1.8 A. PCB layout with ≥1 cm² copper connected to the drain tab is required to maintain RthJA ≤ 80 K/W and avoid exceeding this limit under full load.
Can BSP320S E6327 be used in high-frequency PWM applications?
Yes-it supports PWM frequencies up to 1 MHz due to low total gate charge (QG = 10 nC) and fast switching times (ton ≈ 12 ns, toff ≈ 25 ns). Gate resistor selection must limit dV/dt to <5 V/ns to prevent spurious turn-on; typical RG = 10 Ω achieves this with 5 V logic drivers.
Does BSP320S E6327 require a gate pull-up resistor in low-side switch configuration?
No-when used as a low-side switch, the gate is actively driven low to turn on and high (to source potential) to turn off. A pull-up resistor is unnecessary and would impede turn-off speed. In high-side configurations, a gate pull-down resistor (e.g., 10 kΩ) is recommended to ensure defined off-state during controller reset.
Is the body diode suitable for freewheeling inductive loads?
Yes-the integrated body diode is fully characterized with trr = 45 ns and Qrr = 25 nC, making it suitable for freewheeling in relay coils and small solenoids. For high-energy inductive loads (>100 mJ), external Schottky clamping is advised to reduce diode stress and improve efficiency.
