Product details

Overview

BSD340NH6327XTSA1 from Infineon Technologies is a dual N-channel enhancement-mode MOSFET in SOT-363-6 package, rated for 30 V drain-source voltage, 600 mΩ max R_DS(on) at 4.5 V gate drive, and 0.88 A continuous drain current. It supports logic-level operation, is AEC-Q101 qualified, and features integrated avalanche-rated body diodes for robust switching in space-constrained automotive and industrial load switches.

For engineers reviewing the BSD340NH6327XTSA1 datasheet, BSD340NH6327XTSA1 pinout, BSD340NH6327XTSA1 application, or BSD340NH6327XTSA1 equivalent, key selection criteria include dual-channel logic-level gate drive compatibility, thermal resistance (250 K/W), avalanche energy rating (1.6 mJ), and RoHS/halogen-free compliance for automotive-grade reliability.

Technical Context

This dual MOSFET integrates two independent N-channel OptiMOS™2 small-signal transistors sharing a common source configuration in a single SOT-363 package. Each channel operates with a gate threshold voltage of 1.2–2.0 V and supports fast switching via low gate charge (Q_g = 0.46–0.7 nC) and nanosecond-scale turn-on/turn-off times (td(on) = 2.6 ns, tf = 2.5 ns).

Its design targets low-voltage DC load switching where space, thermal management, and transient robustness are critical - including automotive body electronics, LED drivers, and power rail control. The device's 100% lead-free construction and qualification per AEC-Q101 confirm suitability for automotive under-hood and cabin applications requiring long-term reliability.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage before breakdown; defines use in ≤24 V automotive systems.
R_DS(on), max @ 4.5 V	600 mΩ - On-resistance at logic-level gate drive; enables direct MCU GPIO control without level-shifting.
I_D, cont	0.88 A - Continuous drain current per channel at 25 °C; sets thermal derating limit for PCB layout.
E_AS	1.6 mJ - Single-pulse avalanche energy; ensures survivability during inductive load switching transients.
Q_g	0.46–0.7 nC - Total gate charge; determines driver strength requirement and switching loss trade-off.
R_thJA	250 K/W - Junction-to-ambient thermal resistance on minimal footprint PCB; guides heatsinking decisions.
V_GS(th)	1.2–2.0 V - Gate threshold range; confirms reliable turn-on with 3.3 V or 5 V logic signals.

Pinout & Package

Package: PG-SOT363 (SOT-363-6), surface-mount, 6-pin plastic package with exposed drain pad for thermal enhancement.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate of Channel 1	Control input for first MOSFET; requires <2.0 V threshold to ensure full enhancement at 3.3 V logic.
Pin 2	Drain of Channel 1	High-side switch node for Channel 1; electrically isolated from Pin 3 but thermally coupled via shared drain pad.
Pin 3	Drain of Channel 2	High-side switch node for Channel 2; shares thermal path with Pin 2 but operates independently.
Pin 4	Source of Channel 2	Common source terminal for Channel 2; tied to ground or return path in high-side configuration.
Pin 5	Source of Channel 1	Common source terminal for Channel 1; may be internally connected to Pin 4 depending on variant - confirmed discrete in BSD340N.
Pin 6	Gate of Channel 2	Control input for second MOSFET; fully independent of Pin 1 for dual asynchronous switching.

Key Features

Feature	Design Value
Dual N-channel topology	Two independent 30 V MOSFETs in one SOT-363 package - reduces board area by ~40% vs. discrete solutions.
Logic-level gate drive	Guaranteed turn-on at V_GS = 4.5 V with R_DS(on) ≤ 600 mΩ - eliminates need for gate drivers in 3.3 V/5 V microcontroller interfaces.

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	Higher R_DS(on) (1.5 Ω @ 4.5 V), lower V_DS (50 V), same SOT-363 package	Not AEC-Q101 qualified; suited for consumer-grade signal switching only	Select when cost sensitivity outweighs automotive qualification and higher on-resistance is acceptable.
DMN3028LSD-13	Lower R_DS(on) (28 mΩ @ 10 V), SO-8 package, no AEC-Q101 rating	Requires gate driver for logic-level operation; larger footprint limits space-constrained designs	Choose when higher current (3.5 A) and lower conduction loss are prioritized over package size and automotive compliance.

Compared with BSS138DW-7-F and DMN3028LSD-13, BSD340NH6327XTSA1 uniquely balances AEC-Q101 qualification, logic-level drive, dual-channel integration in SOT-363, and 30 V/0.88 A capability - making it optimal for automotive body electronics where footprint, reliability, and MCU compatibility are jointly constrained.

FAQ

Is BSD340NH6327XTSA1 suitable for high-frequency PWM switching above 1 MHz?

Yes - its typical turn-on delay (2.6 ns), rise time (6.3 ns), and low gate charge (0.46–0.7 nC) support clean switching up to 2 MHz in low-duty-cycle applications. However, thermal limits (0.5 W P_tot) require careful duty cycle and PCB copper area management above 500 kHz.

Does BSD340NH6327XTSA1 have internal ESD protection diodes?

Yes - it is rated ESD Class 0 per JESD22-A114 (HBM < 250 V), indicating integrated gate protection structures. This provides basic handling robustness but does not replace system-level TVS protection for hot-plug or cable discharge events.

Can the two channels be used in parallel to increase current capacity?

No - the channels are electrically isolated but share thermal mass and have mismatched R_DS(on) tolerances (±20%). Parallel use risks current imbalance and thermal runaway; the datasheet specifies maximum per-channel current (0.88 A) and does not endorse paralleling.

What is the maximum allowable PCB trace width for thermal performance in minimal footprint layout?

The datasheet specifies thermal testing on 1 mm wide × 70 µm thick copper traces on both sides of a 40 mm × 40 mm FR4 board. For optimal R_thJA = 250 K/W, maintain ≥1 mm trace width per drain/source connection and use thermal vias under the exposed drain pad to inner ground planes.
