Product details
Overview
BSP320SL6327HTSA1 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in PG-SOT223 package, with 200 V VDS, 1.5 A ID (continuous), and 2.5 Ω RDS(on) at VGS = 10 V, used for low-side switching in automotive body control modules and LED lighting drivers.
For engineers reviewing the BSP320SL6327HTSA1 datasheet, BSP320SL6327HTSA1 pinout, BSP320SL6327HTSA1 application, or BSP320SL6327HTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, SOT223 thermal performance, 200 V blocking capability, and gate threshold voltage of 2.5 V (typical) for 3.3 V logic-level drive compatibility.
Technical Context
This MOSFET operates as a single N-channel silicon device with enhancement-mode behavior, requiring positive gate-source voltage to conduct. Its 200 V VDS rating supports 12 V and 24 V automotive battery systems with load dump margin, while the 2.5 Ω RDS(on) enables <1.5 W conduction loss at 1.5 A DC current under standard heatsinking.
The PG-SOT223 package features an exposed drain pad for improved thermal dissipation (RthJA = 80 K/W typical on 1-in² 2-oz copper), and the device is specified for operation from −55 °C to +150 °C junction temperature, meeting under-hood automotive environmental requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 200 V - supports 24 V automotive systems with ISO 7637-2 pulse immunity margin |
| ID (continuous) | 1.5 A - delivers sufficient current for driving solenoids, relays, or multi-string LED loads |
| RDS(on) @ VGS=10 V | 2.5 Ω - limits conduction loss to ≤5.6 W at 1.5 A in worst-case thermal conditions |
| VGS(th) | 2.5 V (typ) - ensures reliable turn-on with 3.3 V microcontroller GPIO without level-shifting |
| Qg | 9.5 nC - enables fast switching with moderate gate driver strength (e.g., TC4427) |
| TJ range | −55 °C to +150 °C - qualified for engine bay and headlamp module placement |
Pinout & Package
Package: PG-SOT223 (leadless variant of SOT-223, with exposed drain pad on bottom surface, standardized JEDEC MO-178AB footprint).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Reference node for gate drive; connects to ground or low-side return path |
| Pin 2 (Gate) | Control input | Receives logic-level signal; requires <10 µA leakage current for stable bias |
| Pin 3 (Drain) | Power output | High-side connection to load; electrically tied to exposed pad for thermal conduction |
| Exposed Pad | Drain (thermal & electrical) | Must be soldered to PCB copper pour for RthJA ≤ 80 K/W; not isolated |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements including HTGB, HTRB, and ESD-HBM ≥2 kV |
| Pb-free & RoHS compliant | Meets EU Directive 2011/65/EU; lead plating replaced with pure tin, eliminating post-soldering whisker risk |
| Logic-level gate drive | VGS(th) max 3.5 V ensures full enhancement with 3.3 V MCU outputs without external level shifters |
| Thermally enhanced SOT223 | Exposed drain pad reduces junction-to-ambient resistance by ~35% vs. standard SOT-223 |
Applications
| Automotive Body Control Unit | LED Headlamp Driver |
|---|---|
Use Scenario: Switching 12 V incandescent or LED loads (e.g., door locks, interior lighting) in BCMs. IC Role / Device Role / Timing Role: Low-side power switch controlling load current path to chassis ground. Use Value: AEC-Q101 qualification ensures reliability over 15-year vehicle lifetime; 2.5 Ω RDS(on) minimizes self-heating during PWM dimming. | Use Scenario: Driving high-brightness LED strings in adaptive front-lighting systems (AFS). IC Role / Device Role / Timing Role: Constant-current sink switch modulated via MCU PWM at 1–2 kHz. Use Value: 200 V VDS withstands load-dump transients up to ±100 V; fast Qg enables clean PWM edges without shoot-through risk. |

IC Role / Device Role / Timing Role: H-bridge half-bridge low-side switch paired with complementary high-side device. Use Value: Low gate charge (9.5 nC) allows efficient 20 kHz PWM operation with minimal gate driver power loss. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP16NF20 | TO-220 package, 200 V, 16 A ID, 0.15 Ω RDS(on); higher current, larger footprint, no AEC-Q101 | Suitable for higher-power industrial motor drives but lacks automotive qualification and compact SOT223 form factor | Select when board space permits and >1.5 A continuous current is required; verify gate drive compatibility due to higher Qg (32 nC) |
| BSP120 | SOT-223, 200 V, 0.85 A ID, 3.5 Ω RDS(on); AEC-Q101 qualified, lower current rating | Matches footprint and qualification but insufficient for >1.2 A loads; higher conduction loss at same current | Choose only for cost-sensitive, low-current (<0.8 A) automotive switches where thermal margin is ample |
Compared with STP16NF20 and BSP120, BSP320SL6327HTSA1 uniquely balances AEC-Q101 compliance, SOT223 board area, 1.5 A capability, and 2.5 Ω RDS(on)-making it optimal for space-constrained automotive modules needing verified reliability without over-engineering.

FAQ
Is BSP320SL6327HTSA1 suitable for 24 V commercial vehicle applications?
Yes. Its 200 V VDS rating exceeds ISO 16750-2 load-dump requirements (up to 120 V transient), and AEC-Q101 qualification covers extended temperature cycling, humidity, and mechanical shock tests required for trucks and buses. The PG-SOT223 package maintains thermal stability up to +150 °C junction temperature.
What is the recommended PCB layout for thermal performance?
Use a minimum 10 mm² copper pour connected directly to the exposed drain pad with ≥4 thermal vias (0.3 mm diameter, filled or plated) to inner-layer ground planes. Keep gate traces short and away from noisy power paths to avoid coupling; add 100 Ω series gate resistor to damp ringing during fast switching.
Does this MOSFET require a gate pull-down resistor in automotive applications?
Yes. A 10 kΩ pull-down resistor from gate to source is recommended to prevent spurious turn-on during MCU reset or power-up sequences. This mitigates risk of unintended load activation-a critical safety requirement in ISO 26262-compliant designs where BSP320SL6327HTSA1 may serve as a safety-related switch.
Can BSP320SL6327HTSA1 replace BSP120 in existing designs?
Yes, with verification. Both share PG-SOT223 footprint and AEC-Q101 qualification, but BSP320SL6327HTSA1 offers 76% higher ID (1.5 A vs. 0.85 A) and 29% lower RDS(on) (2.5 Ω vs. 3.5 Ω). Confirm thermal margin and gate drive strength, as higher current capability may expose marginal layout or driver limitations.
