Product details
Overview
BSP372 E6327 from Infineon Technologies is an N-channel logic-level SIPMOS® small-signal power MOSFET rated for 100 V VDS, 1.7 A continuous drain current, and 0.31 Ω RDS(on) at VGS = 5 V. It features avalanche rating (EAS = 45 mJ), AEC-Q101 qualification, and operates with gate threshold voltage as low as 0.8 V - enabling direct drive from 3.3 V microcontrollers in automotive body electronics.
For engineers reviewing the BSP372 E6327 datasheet, BSP372 E6327 pinout, BSP372 E6327 application, or BSP372 E6327 equivalent, key selection criteria include its logic-level gate drive compatibility, integrated body diode with trr = 65 ns, thermal resistance RthJA ≤ 70 K/W on standard PCB, and SOT-223 package suitability for space-constrained 12 V/24 V DC load switching.
Technical Context
This discrete N-channel enhancement-mode MOSFET uses trench-based SIPMOS® technology to achieve low RDS(on) and fast switching (td(on) ≤ 30 ns, tf ≤ 75 ns) while maintaining robust avalanche capability. Its gate threshold range (0.8–2.0 V) ensures reliable turn-on across temperature and process variation.
The device integrates a monolithic body diode with VSD = 0.85–1.1 V at IF = 1.7 A and trr = 65 ns under defined dI/dt conditions, supporting synchronous rectification and inductive load commutation without external diode addition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - supports 24 V automotive systems with ≥4× safety margin against transients |
| ID (continuous) | 1.7 A at TA = 28 °C - suitable for medium-power solenoid, LED, and fan drivers |
| RDS(on) | 0.31 Ω max at VGS = 5 V - enables <1 W conduction loss at full load |
| VGS(th) | 0.8–2.0 V - guarantees turn-on with 3.3 V logic without level-shifting circuitry |
| EAS | 45 mJ - withstands single-pulse inductive energy without failure in relay/coil driving |
| Ciss | 520 pF max - limits gate drive power requirement for PWM frequencies up to 500 kHz |
| trr | 65 ns - reduces switching losses and EMI in flyback and buck converters |
Pinout & Package
Package: PG-SOT223 (standard SOT-223 outline with exposed drain pad for thermal performance).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Gate (G) | Control terminal; low input capacitance (Ciss ≤ 520 pF) eases drive from MCU GPIO |
| Pin 2 | Drain (D) | Main current path output; electrically connected to exposed pad for thermal conduction |
| Pin 3 | Source (S) | Reference node for gate drive; ties to ground or low-side return path |
| Pin 4 | Drain (D) | Second drain connection - paralleled with Pin 2 to reduce package inductance and improve thermal spreading |
Key Features

|---|---|
| Logic-level gate drive | VGS(th) down to 0.8 V enables direct interface with 3.3 V microcontrollers and ASICs |
| Avalanche-rated operation | Guaranteed single-pulse EAS = 45 mJ supports unclamped inductive switching in automotive loads |
| AEC-Q101 qualified | Validated for automotive applications including interior lighting, HVAC actuators, and body control modules |
| Integrated body diode | VSD = 0.85 V typ at 1.7 A allows efficient freewheeling without external diode in low-frequency switching |
| SOT-223 thermal design | RthJA ≤ 70 K/W on 40 mm × 40 mm PCB with 6 cm² copper - enables >1 W dissipation without heatsink |
Applications
| Automotive Interior Lighting | 12 V DC Fan Control |
|---|---|
Use Scenario: Switching LED strips and incandescent bulbs in door modules and ambient lighting. IC Role / Device Role / Timing Role: Low-side power switch controlled by BCM microcontroller PWM output.

Use Value: Coss = 100 pF max and trr = 65 ns enable rapid reverse blocking after supply switchover, reducing cross-conduction loss. |
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 |
|---|---|---|---|
| STP3NK60ZFP | 600 V VDS, 2.6 A ID, 3.3 Ω RDS(on) - higher voltage rating but 10× higher on-resistance | Designed for high-voltage SMPS primary side; unsuitable for 12/24 V logic-driven loads | Select only if system requires >100 V blocking and can tolerate higher conduction loss |
| DMN3028LSD-13 | 30 V VDS, 7.5 A ID, 28 mΩ RDS(on) - lower voltage, higher current, smaller footprint (SOT-23) | Optimized for portable battery-powered devices; lacks AEC-Q101 and avalanche rating | Prefer for consumer-grade 3.3/5 V systems where automotive reliability is not required |
Compared with STP3NK60ZFP and DMN3028LSD-13, the BSP372 E6327 uniquely balances 100 V rating, logic-level drive, AEC-Q101 compliance, and SOT-223 thermal capability - making it the only option validated for automotive 12 V/24 V body electronics requiring robustness and MCU compatibility.

FAQ
Is BSP372 E6327 suitable for 3.3 V microcontroller drive without a gate driver?
Yes. With VGS(th) as low as 0.8 V and guaranteed RDS(on) ≤ 0.31 Ω at VGS = 5 V, the device fully enhances using standard 3.3 V GPIO outputs. Measured gfs = 3.7 S ensures strong transconductance even at low gate voltages, enabling robust switching at 1.7 A load current.
What is the maximum safe operating temperature for continuous operation?
The junction temperature must not exceed +150 °C. At TA = 85 °C, derated continuous ID is ~1.1 A (per ID vs. TA graph). With 6 cm² copper on a 1.5 mm FR4 board, Ptot remains ≥1.2 W up to 85 °C ambient - sufficient for most sealed automotive enclosures without forced airflow.
Does BSP372 E6327 include a built-in ESD protection diode?
No. The device has no integrated ESD protection structure. External TVS diodes (e.g., PESD5V0S1BA) are recommended on gate and drain lines in automotive environments per ISO 10605 requirements, especially when exposed to connector interfaces or long traces.
Can BSP372 E6327 replace older BSP372 variants like E6327 in existing designs?
Yes. BSP372 E6327 is a tape-and-reel packaging variant of the same die and specification as the base BSP372. Electrical parameters, thermal behavior, and pinout are identical to Rev 2.0 datasheet - ensuring drop-in compatibility in SOT-223 footprints and automated assembly processes.
