Product details
Overview
BSD316SNH6327XTSA1 from Infineon Technologies is an N-channel logic-level enhancement-mode MOSFET rated for 30 V VDS, 1.4 A continuous drain current at 25 °C, and 280 mΩ RDS(on) at VGS = 4.5 V; it is AEC-Q101 qualified, avalanche-rated, and housed in a PG-SOT363 (SOT-363) package for space-constrained automotive signal switching applications.
For engineers reviewing the BSD316SNH6327XTSA1 datasheet, BSD316SNH6327XTSA1 pinout, BSD316SNH6327XTSA1 application, or BSD316SNH6327XTSA1 equivalent, key selection criteria include its 4.5 V logic-level gate drive compatibility, 100% lead-free RoHS/halogen-free construction, -55 to 150 °C operating temperature range, and validated avalanche energy of 3.7 mJ under defined test conditions.
Technical Context
This discrete power MOSFET operates in enhancement mode with a typical gate threshold voltage of 1.6 V and maximum of 2.0 V, enabling reliable turn-on with standard logic-level microcontrollers. Its low 71–94 pF input capacitance and 5–7 pF reverse transfer capacitance support fast switching in low-power DC-DC and load-switching circuits.
The device integrates a co-packaged body diode with 0.8–1.1 V forward voltage at 1.4 A and 9.1 ns reverse recovery time, suitable for synchronous rectification and flyback snubbing where controlled diode conduction is required.
Key Specifications

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 @ 4.5 V), SOT-323 package | Not suitable for >500 mA loads; limited to signal-level switching only | Select only for ultra-low-current digital isolation where power handling is secondary |
| DMN3028LSD-13 (Diodes Inc.) | Same VDS (30 V), lower RDS(on) (22 mΩ @ 10 V), but requires 10 V gate for full spec; SOT-23-6 | Needs external level shifter for 3.3 V logic; better for high-efficiency DC-DC, not logic-driven loads | Prefer when gate drive can supply ≥10 V and RDS(on) reduction outweighs logic compatibility loss |
Compared with BSS138W and DMN3028LSD, BSD316SNH6327XTSA1 uniquely balances 4.5 V logic compatibility, AEC-Q101 qualification, and 1.4 A capability in a 6-pin SOT-363 - making it optimal for automotive body electronics where reliability, size, and direct MCU drive converge.

FAQ
Is BSD316SNH6327XTSA1 suitable for 3.3 V microcontroller gate drive?
Yes. With a maximum gate threshold voltage of 2.0 V and guaranteed RDS(on) at VGS = 4.5 V, it turns on fully using 3.3 V logic when paired with appropriate pull-down design. However, RDS(on) increases to ~380 mΩ at 3.3 V - verify voltage drop and thermal rise for your load current.
What is the maximum safe operating frequency for PWM switching?
Based on 0.6 nC total gate charge and typical 6 Ω gate resistor, the device supports clean switching up to ~500 kHz. At 1 MHz, gate drive losses increase significantly; use optimized gate driver layout and consider thermal derating above 250 kHz continuous operation.
Does the dual-drain/dual-source configuration require special PCB layout?
Yes. Pins 3 and 5 are internally connected drains; pins 1 and 4 are internally connected sources. To minimize loop inductance and thermal resistance, route wide copper polygons connecting both drain pins and both source pins respectively - avoid daisy-chaining traces between them.
Can BSD316SNH6327XTSA1 replace a BSS138 in existing designs?
No - not directly. While both are N-channel SOT-363/SOT-23 devices, BSD316SN handles 1.4 A vs. BSS138's 0.3 A and has different pinout (dual-source/drain). Layout, thermal, and drive strength changes are required; redesign verification is mandatory before substitution.
