Product details
Overview
BSD816SNL6327HTSA1 from Infineon Technologies is an N-channel enhancement-mode small-signal MOSFET with 20 V VDS, 1.4 A continuous drain current, and ultra-low 1.8 V logic-level gate drive capability. It features avalanche rating, AEC-Q101 qualification, and 240 mΩ RDS(on) at VGS = 1.8 V, enabling use in automotive load switching and space-constrained DC-DC converter high-side control.
For engineers reviewing the BSD816SNL6327HTSA1 datasheet, BSD816SNL6327HTSA1 pinout, BSD816SNL6327HTSA1 application, or BSD816SNL6327HTSA1 equivalent, key selection factors include its 1.8 V threshold compatibility with low-voltage microcontrollers, SOT-363 (PG-SOT363) package thermal resistance of 250 K/W, and integrated body diode with 8.1 ns reverse recovery time for synchronous rectification support.
Technical Context
This device operates as a logic-level power switch optimized for 1.8–2.5 V gate drive systems. Its 0.55 V typical gate threshold voltage and 158 mΩ RDS(on) at VGS = 2.5 V ensure robust conduction under low-voltage MCU I/O conditions while maintaining 20 V breakdown margin.
Designed for automotive-grade reliability, it supports pulsed drain currents up to 5.6 A and single-pulse avalanche energy of 3.7 mJ. The integrated Schottky-like body diode delivers 0.87 V forward voltage at 1.4 A and enables fast 8.1 ns trr in flyback or buck-boost topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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) | 30 V VDS, 220 mΩ RDS(on) @ VGS=2.5 V, no AEC-Q101 qualification | Not rated for automotive temperature cycling or humidity testing | Preferred for cost-sensitive consumer IoT where 20 V rating suffices and qualification is unnecessary |
| DMN2016LFG-7 (Diodes Inc.) | 20 V VDS, 190 mΩ RDS(on) @ VGS=2.5 V, 1.2 V VGS(th) min, no avalanche rating | Lacks single-pulse avalanche energy spec; unsuitable for inductive load switching | Selected when lower RDS(on) is critical and load is purely resistive or capacitive |
Compared with BSS138W and DMN2016LFG-7, BSD816SNL6327HTSA1 uniquely combines AEC-Q101 qualification, 1.8 V logic compatibility, and guaranteed avalanche ruggedness-making it the only option qualified for automotive body electronics with inductive loads.

FAQ
Is BSD816SNL6327HTSA1 suitable for 1.8 V microcontroller GPIO direct drive?
Yes. With a typical gate threshold voltage of 0.55 V and guaranteed turn-on at VGS = 1.8 V, this MOSFET fully enhances using standard 1.8 V logic outputs without external level shifters. Its 240 mΩ RDS(on) at 1.8 V supports 1.1 A continuous current at 70 °C ambient, validated per AEC-Q101 thermal cycling tests.
What is the maximum safe operating frequency for PWM switching?
Based on measured 9.0 ns rise time and 2.2 ns fall time with 6 Ω external gate resistor, the device supports clean switching up to 10 MHz in low-duty-cycle applications. For continuous 50% duty cycle, thermal limits constrain practical operation to ≤2 MHz at 1.4 A due to 250 K/W RthJA on minimal FR4 footprint.
Does the SOT-363 package require solder paste stencil optimization?
Yes. The PG-SOT363 package uses a thermally enhanced leadframe with exposed die pad. Recommended stencil aperture is 0.15 mm thick with 80% area ratio; reflow profile must peak at 260 °C for ≤10 seconds to ensure void-free thermal pad wetting while maintaining RoHS-compliant intermetallic formation.
Can BSD816SNL6327HTSA1 replace a BSS138 in existing designs?
It can functionally replace BSS138 in 20 V-rated circuits but requires layout review: BSD816SN has dual-drain/dual-source pins (Pins 3/6 and 1/4), whereas BSS138 uses single-drain/single-source SOT-23. Pin mapping differs, and the higher 5.6 A pulsed rating may necessitate updated gate drive strength verification.
