Product details
Overview
BSL802SNL6327HTSA1 from Infineon Technologies is an N-channel enhancement-mode small-signal MOSFET optimized for ultra-low-voltage logic-level drive (1.8 V rated), with 20 V VDS, 7.5 A ID (TA = 25 °C), and 22 mΩ RDS(on) at VGS = 2.5 V. It is AEC-Q101 qualified, avalanche-rated, and used in automotive body electronics, LED drivers, and load switching where fast switching and robust transient handling are required.
For engineers reviewing the BSL802SNL6327HTSA1 datasheet, BSL802SNL6327HTSA1 pinout, BSL802SNL6327HTSA1 application, or BSL802SNL6327HTSA1 equivalent, key selection criteria include its 1.8 V logic compatibility, 30 mJ single-pulse avalanche energy, 6 kV/µs di/dt ruggedness, and TSOP6 package thermal performance under constrained PCB layouts.
Technical Context
This device operates as a discrete power switch in low-voltage DC-DC point-of-load regulation and high-side/low-side load control. Its gate threshold voltage (0.3–0.75 V) enables reliable turn-on with 1.8 V microcontroller GPIO, while its 1013 pF Ciss and 4.7 nC Qg support efficient 1–10 MHz switching in space-constrained applications.
The integrated body diode exhibits 15 ns trr and 5.1 nC Qrr at 10 V reverse bias, enabling synchronous rectification in buck converters. Thermal resistance RthJA is 62.5 K/W with 6 cm² copper area, confirming suitability for thermally demanding automotive modules without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 20 V - maximum blocking voltage compatible with 12 V automotive systems and 5 V logic-supplied rails |
| RDS(on) @ VGS = 2.5 V | 22 mΩ max - ensures ≤0.125 W conduction loss at 7.5 A, minimizing self-heating on minimal-footprint PCBs |
| ID (continuous) | 7.5 A @ TA = 25 °C - supports high-current digital loads such as solenoid drivers and motor gate logic |
| EAS | 30 mJ - withstands inductive kickback from relay coils and brushed DC motors without failure |
| Ciss | 1013–1347 pF - defines gate drive strength requirement; compatible with standard 3.3 V/5 V logic drivers |
| tr/tf | 30 ns / 5.5 ns - enables clean edge transitions in PWM dimming and Class-D audio output stages |
| Qg | 4.7 nC - determines gate driver current demand; allows use of low-power MCU GPIO with series resistor |
Pinout & Package
BSL802SNL6327HTSA1 is housed in a PG-TSOP6 surface-mount package (3.05 × 1.5 mm footprint, 0.95 mm height), optimized for automated assembly and thermal dissipation via exposed drain pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for channel conduction | Internally connected to substrate; requires low-impedance ground plane for EMI control and thermal relief |
| 2 (Gate) | Control electrode for channel modulation | High-impedance input; sensitive to ESD-requires series resistor (10–100 Ω) and local decoupling |
| 3 (Drain) | Main current-carrying terminal (power output) | Exposed pad on bottom; must be soldered to ≥6 cm² copper area for RthJA = 62.5 K/W |
| 4 (Source) | Redundant source connection | Parallel path to Pin 1; improves current sharing and reduces bond wire inductance in high-di/dt switching |
| 5 (Drain) | Primary drain terminal | Electrically tied to Pin 3; provides second routing option for compact layout and thermal symmetry |
| 6 (Gate) | Secondary gate connection | Internally bonded to Pin 2; reduces gate loop inductance for stable 10+ MHz operation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra Logic-Level Gate Drive | Guaranteed turn-on at VGS = 1.8 V, enabling direct interface with modern low-voltage MCUs (e.g., ARM Cortex-M0+) without level shifters |

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 |
|---|---|---|---|
| BSS138W,115 (Nexperia) | Lower ID (0.3 A), higher RDS(on) (3.5 Ω @ VGS = 2.5 V), SOT-323 package | Suitable only for signal switching (<100 mA); not rated for automotive or power switching | Select when only signal-level isolation is needed and board space is extreme constraint. |
| DMN2004LK-7 (Diodes Inc.) | Same VDS (20 V), higher RDS(on) (30 mΩ @ VGS = 2.5 V), 6.5 A ID, same TSOP6 footprint | Compatible pinout but lower avalanche rating (15 mJ) and no AEC-Q101 qualification | Acceptable for industrial non-automotive use where cost is prioritized over transient ruggedness. |

FAQ
Is BSL802SNL6327HTSA1 suitable for high-frequency switching above 1 MHz?
Yes. With 30 ns rise time, 5.5 ns fall time, and 4.7 nC total gate charge, it supports clean switching up to 10 MHz in buck converter topologies. Layout must minimize gate loop inductance-use short traces, ground plane under gate, and avoid vias in gate path.
What is the maximum allowable PCB temperature rise during continuous 7.5 A operation?
At 7.5 A and 25 °C ambient, junction temperature reaches ~125 °C with 6 cm² copper cooling (RthJA = 62.5 K/W). To stay within 150 °C Tj,max, ambient must remain ≤25 °C or copper area increased to ≥10 cm² for sustained load.
Does BSL802SNL6327HTSA1 require a gate resistor for MCU-driven operation?
Yes. A 22–47 Ω series gate resistor is recommended to dampen ringing caused by 1013 pF Ciss interacting with PCB trace inductance. This prevents false triggering and reduces EMI emissions during 1.8 V GPIO switching.
Can this MOSFET replace a mechanical relay in automotive door lock circuits?
Yes. Its 30 mJ avalanche rating and 6 kV/µs dv/dt immunity allow direct replacement of 12 V relays driving inductive solenoids (≤7.5 A). No external flyback diode is needed, reducing component count and improving long-term reliability versus electromechanical contacts.
