Product details
Overview
BSD816SNH6327XTSA1 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 LED drivers and low-voltage load switching.
For engineers reviewing the BSD816SNH6327XTSA1 datasheet, BSD816SNH6327XTSA1 pinout, BSD816SNH6327XTSA1 application, or BSD816SNH6327XTSA1 equivalent, key selection criteria include logic-level gate compatibility, SOT363 footprint constraints, avalanche robustness for inductive loads, and AEC-Q101 compliance for automotive subsystems.
Technical Context
This device operates as a single N-channel power switch optimized for 1.8–2.5 V control interfaces in space-constrained automotive and industrial modules. Its 240 mΩ RDS(on) at 1.8 V enables direct microcontroller GPIO driving without level-shifting, while its 3.7 mJ single-pulse avalanche energy supports reliable operation with inductive flyback transients.
The PG-SOT363 package integrates three terminals per channel (source, gate, drain) in a dual-channel configuration - confirmed by marking "XAs" and pinout diagrams showing pins 1–3 and 4–6 as two independent MOSFETs - with thermal resistance of 250 K/W on minimal FR4 footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 20 V - maximum blocking voltage for 12 V automotive rail and 5 V logic-supplied loads |
| RDS(on) @ VGS=1.8 V | 240 mΩ - enables 1.4 A continuous conduction with ≤0.5 W conduction loss at TA=25°C |
| ID continuous | 1.4 A @ TA=25°C - supports LED string drivers and sensor interface switches |
| EAS | 3.7 mJ - withstands single-pulse inductive energy from solenoid/relay coils without failure |
| Qg | 0.6 nC - ensures fast switching (<15 ns rise/fall) with low gate-drive power demand |
| Tj range | −55 to +150°C - qualified for under-hood automotive environments per AEC-Q101 |
| Ciss | 126–180 pF - determines gate drive impedance requirements and EMI filtering needs |
Pinout & Package
Package: PG-SOT363 (3.0 × 1.8 × 0.9 mm), lead-free, halogen-free, tape-and-reel (3000 pcs/reel, H6327 marking).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Source (Channel 1) | Low-side return path for first MOSFET; tied to PCB ground plane for thermal and electrical reference |
| Pin 2 | Gate (Channel 1) | Logic-level input requiring ≤1.8 V threshold; decoupling capacitor placement critical near this pin |
| Pin 3 | Drain (Channel 1) | Switched high-side output; routed with minimum loop area to reduce EMI from switching edges |
| Pin 4 | Drain (Channel 2) | Independent high-side output for dual-load control; electrically isolated from Channel 1 drain |
| Pin 5 | Gate (Channel 2) | Second logic-level input; requires separate gate resistor for independent timing control |
| Pin 6 | Source (Channel 2) | Second low-side return; may be commoned with Pin 1 or kept separate for current sensing |
Key Features
| Feature | Design Value |
|---|---|
| Ultra logic-level gate | 1.8 V rated threshold enables direct interfacing with 1.8 V/2.5 V MCUs 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-7-F | Lower ID (220 mA), higher RDS(on) (3.5 Ω @ 2.5 V), no avalanche rating | Suitable only for signal switching, not power loads | Select only for low-current digital isolation where avalanche robustness is unnecessary |
| DMN2004K-7 | Higher RDS(on) (300 mΩ @ 2.5 V), same 20 V rating, no AEC-Q101 qualification | Lacks automotive qualification and lower gate-threshold margin | Acceptable for industrial non-automotive use but requires external transient protection |
Compared with BSS138W-7-F and DMN2004K-7, BSD816SNH6327XTSA1 uniquely combines AEC-Q101 qualification, 1.8 V logic compatibility, and 3.7 mJ avalanche capability - making it the only option qualified for automotive load-switching where reliability under transient stress is mandatory.

FAQ
Is BSD816SNH6327XTSA1 pin-compatible with BSD816SH6327XTSA1?
No. BSD816SNH6327XTSA1 is an N-channel dual MOSFET in PG-SOT363; BSD816SH6327XTSA1 is a P-channel variant with opposite polarity and different threshold behavior. Pin assignments differ in functional role - e.g., Pin 2 is gate for both, but source/drain orientation is inverted - requiring schematic and layout revision.
What is the maximum allowable gate-source voltage during transient conditions?
The absolute maximum VGS is ±8 V per datasheet Rev 2.5. Operation beyond ±6 V risks oxide damage, especially during hot-plug or ESD events. A 4.7 kΩ series gate resistor and 5.6 V Zener clamp are recommended for robust 12 V system integration.
Does the device support parallel operation for higher current handling?
Yes, but with strict layout controls: matched gate trace lengths, individual gate resistors (≤10 Ω), and symmetrical thermal vias under each source pad. Derating to 1.1 A per device is required at TA = 70°C due to thermal coupling in shared SOT363 footprint.
How does the 250 K/W RthJA value translate to real-world thermal performance?
On a 40 mm² FR4 PCB with 1 mm wide, 70 µm thick copper traces on both sides, junction-to-ambient rise is 250 K per watt. At 1.4 A and 240 mΩ, PD ≈ 0.47 W → ΔT ≈ 118°C above ambient. Thus, max TA must be limited to 32°C to hold Tj ≤ 150°C.
