Product details
Overview
BSL205NL6327HTSA1 from Infineon Technologies is a dual N-channel enhancement-mode MOSFET in PG-TSOP6 package, rated for 20 V VDS, 2.5 A continuous drain current (TA = 25 °C), and 50 mΩ RDS(on) at VGS = 4.5 V. It features Super Logic-level gate drive (2.5 V rated), AEC-Q101 qualification, and avalanche energy rating of 10.8 mJ - used in automotive body control modules for low-side load switching.
For engineers reviewing the BSL205NL6327HTSA1 datasheet, BSL205NL6327HTSA1 pinout, BSL205NL6327HTSA1 application, or BSL205NL6327HTSA1 equivalent, key selection criteria include logic-level gate compatibility with 2.5 V microcontrollers, dual-channel integration for space-constrained PCBs, RDS(on) stability across temperature, and AEC-Q101 compliance for under-hood automotive use.
Technical Context
This dual N-channel MOSFET operates in enhancement mode with gate threshold voltage ranging 0.6–1.2 V and supports parallel channel operation with independent source terminals. Its 2.5 V logic-level gate enables direct drive from 3.3 V or 2.5 V MCUs without level-shifting circuitry.
The device integrates an intrinsic body diode with 10 ns reverse recovery time and 2.2 nC Qrr, supporting fast-switching DC-DC synchronous rectification and PWM-controlled LED drivers where diode conduction occurs during dead-time intervals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS max | 20 V - supports 12 V automotive systems with margin for load-dump transients |
| RDS(on) @ 4.5 V | 50 mΩ max - enables ≤125 mW conduction loss at 2.5 A, reducing thermal footprint |
| ID cont @ 25 °C | 2.5 A - sufficient for driving solenoids, relays, and small motors in BCM applications |
| VGS(th) | 0.6–1.2 V - ensures reliable turn-on with low-voltage logic controllers and wide process tolerance |
| EAS | 10.8 mJ - withstands inductive kickback from automotive loads without failure |
| Qg total | 2.1–3.2 nC - enables fast switching with low gate-drive power, suitable for 100 kHz+ PWM |
| Ciss | 315–419 pF - determines gate drive strength requirement and EMI behavior in high-speed switching |
Pinout & Package
Package: PG-TSOP6 - surface-mount, thermally enhanced 6-pin thin shrink small-outline package with exposed drain pad for improved heat dissipation on standard FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source 1 / Source 2 / Drain 1 | Independent source terminals per channel; Drain 1 shared with Pin 3 for first FET |
| 4, 5, 6 | Gate 1 / Drain 2 / Source 2 | Gate 1 controls Channel 1; Drain 2 and Source 2 form second FET; Pin 6 is Source 2 only |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-channel integration | Two independent logic-level MOSFETs in single PG-TSOP6 footprint - reduces board area by ~40% vs discrete solutions |
| Super Logic-level gate | Guaranteed turn-on at VGS = 2.5 V - eliminates need for gate driver ICs in 3.3 V MCU systems |
| AEC-Q101 qualified | Validated for automotive temperature range (−40 to +150 °C) and mechanical stress - suitable for engine bay and chassis modules |
| Avalanche-rated | 10.8 mJ single-pulse energy handling - protects against inductive switching failures in relay/solenoid drives |
| Halogen-free & RoHS | Complies with IEC61249-2-21 and EU RoHS Directive - meets automotive OEM environmental requirements |
Applications
| Automotive Body Control Module | LED Headlamp Dimming |
|---|---|
Use Scenario: Switching 12 V incandescent and resistive loads (door locks, window lifts, HVAC actuators) in centralized BCM units. IC Role / Device Role / Timing Role: Dual low-side switch providing independent channel control with integrated protection and thermal robustness. Use Value: Reduces component count by replacing two discrete MOSFETs; RDS(on) < 50 mΩ minimizes power loss and PCB heating at 2.5 A peak load. | Use Scenario: PWM dimming of high-brightness LED arrays in adaptive front-lighting systems (AFS). IC Role / Device Role / Timing Role: Synchronous rectifier and current sink in buck-based LED driver topology with 100 kHz+ switching. Use Value: Fast tr/tf (2.9 ns/2.4 ns) and low Qg enable efficient high-frequency dimming; body diode Qrr = 2.2 nC limits switching losses. |
| Industrial PLC Output Stage | USB-C Power Delivery Load Switch |
Use Scenario: Solid-state replacement for electromechanical relays in programmable logic controller digital output modules. IC Role / Device Role / Timing Role: Low-side load switch with overcurrent and thermal fault resilience in 24 V industrial control cabinets. Use Value: Avalanche rating and −55 to +150 °C Tj range ensure reliability under repetitive inductive switching and ambient extremes. | Use Scenario: Inrush current limiting and hot-swap protection for USB-C PD ports delivering up to 5 V/3 A. IC Role / Device Role / Timing Role: Dual-channel power switch enabling redundant or split-rail load management with independent enable control. Use Value: Dual configuration allows fail-safe isolation; 2.5 V logic compatibility aligns with USB-C controller GPIO levels without level shifters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BSS138DW-7-F | Lower ID (0.22 A), higher RDS(on) (3.5 Ω @ 4.5 V), SOT-363 package | Not suitable for >500 mA loads; limited thermal capability | Select only for ultra-low-power signal switching, not power switching |
| DMN2053LSD-13 | Single-channel, same VDS/RDS(on), but requires two devices for dual function | No integrated dual-channel layout; larger PCB area and higher assembly cost | Choose when design requires channel isolation beyond internal separation or different gate biasing |
Compared with BSS138DW-7-F and DMN2053LSD-13, BSL205NL6327HTSA1 uniquely delivers dual-channel 2.5 A switching in a thermally optimized PG-TSOP6 package with AEC-Q101 qualification - making it the only option meeting automotive-grade dual-load requirements in minimal footprint.

FAQ
What is the maximum junction temperature and thermal resistance of BSL205NL6327HTSA1?
The absolute maximum junction temperature is 150 °C. Thermal resistance RthJA is 250 K/W under minimal footprint conditions (40 mm² FR4, 1 mm traces, both sides). This value assumes standard PCB layout - actual thermal performance improves with copper pour and thermal vias under the exposed drain pad.
Does BSL205NL6327HTSA1 support parallel operation of both channels?
Yes - each channel has independent source terminals (Pins 1 & 6), allowing true independent control. However, both drains share no internal connection; Pin 3 is Drain 1 and Pin 5 is Drain 2, enabling separate load connections and independent switching without cross-talk.
Is the body diode suitable for reverse recovery in synchronous rectification?
Yes - the intrinsic body diode has trr = 10 ns and Qrr = 2.2 nC at IF = 2.5 A, making it suitable for synchronous rectification in buck converters operating up to ~500 kHz. Diode forward voltage is 0.8–1.1 V at 2.5 A, contributing to low conduction loss during dead-time conduction.
How does the AEC-Q101 qualification impact design validation for automotive use?
AEC-Q101 qualification confirms that BSL205NL6327HTSA1 passed stress tests including HTGB, HTRB, UHAST, temperature cycling, and mechanical shock - eliminating need for requalification at system level for passenger vehicle applications. It covers full operating range (−40 to +150 °C) and validates robustness against automotive-specific failure modes like bond wire fatigue and moisture-induced corrosion.
