Product details

Overview

BSS7728NH6327XTSA2 from Infineon Technologies is an N-channel enhancement-mode logic-level SIPMOS™ small-signal MOSFET rated for 60 V V_DS, 5 Ω R_DS(on) at V_GS = 4.5 V, and 0.2 A continuous drain current; it is AEC-Q101 qualified and used in low-power load switching and signal routing in automotive body electronics.

For engineers reviewing the BSS7728NH6327XTSA2 datasheet, BSS7728NH6327XTSA2 pinout, BSS7728NH6327XTSA2 application, or BSS7728NH6327XTSA2 equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 1.3–2.3 V), dv/dt ruggedness (6 kV/µs), and halogen-free, Pb-free PG-SOT-23 packaging suitable for space-constrained PCB layouts.

Technical Context

This MOSFET operates in enhancement mode with a threshold voltage tightly specified between 1.3 V and 2.3 V at 25 °C, enabling direct interface with 3.3 V and 5 V logic controllers without level-shifting. Its dv/dt rating of 6 kV/µs ensures robustness against fast transient voltage spikes in inductive load switching.

The device integrates a monolithic body diode with reverse recovery time (t_rr) of 11.5–17.5 ns and Q_rr of 2.6–4 nC, supporting efficient commutation in low-duty-cycle, high-frequency switching applications up to several hundred kHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Max	60 V - supports 24 V automotive systems with 150 % safety margin against load-dump transients
R_DS(on) @ V_GS=4.5 V	4.3–7.5 Ω - enables logic-level MCU GPIO direct drive in low-current switching nodes
I_D Continuous	0.2 A @ T_A=25°C - suitable for LED drivers, sensor biasing, and small solenoid control
V_GS(th)	1.3–2.3 V - guarantees turn-on with standard 3.3 V microcontroller outputs
dv/dt Rating	6 kV/µs - prevents spurious turn-on during high-slew-rate noise events in automotive environments
Q_g Total	1.0–1.5 nC - allows fast switching with minimal gate driver power loss at ≤500 kHz
t_r/t_f	2.7–4.1 ns / 9–13 ns - supports clean edge transitions in timing-critical digital interface circuits

Pinout & Package

Supplied in PG-SOT-23 (JEDEC TO-236AB) package: compact 3-pin surface-mount outline with exposed drain pad for thermal relief; pin 1 = Gate, pin 2 = Source, pin 3 = Drain.

Pin/Terminal	Circuit Role	Design Meaning

Pin 2 (Source)	Reference node	Common return path for load current; tied to system ground or floating reference in high-side configurations
Pin 3 (Drain)	Power output terminal	Connects to switched load; thermally coupled to package backside for enhanced power dissipation

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive under-hood temperature cycling (-40°C to +150°C junction), vibration, and humidity stress
Logic-level gate drive	V_GS(th) max 2.3 V ensures reliable turn-on using 3.3 V I/O without external boost circuitry
dv/dt ruggedness	6 kV/µs rating eliminates need for snubbers in 24 V inductive load switching (e.g., relays, valves)
Halogen-free & Pb-free	Complies with IEC61249-2-21 and RoHS; compatible with lead-free reflow profiles (peak 260°C)

Applications

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 V_DS (50 V), higher R_DS(on) (3.5 Ω @ 10 V), no AEC-Q101 qualification	Suitable for consumer-grade 3.3 V logic interfaces only; not rated for automotive transients	Select when cost sensitivity outweighs automotive qualification and 60 V margin
DMN2004K-7 (Diodes Inc.)	Higher I_D (0.3 A), lower R_DS(on) (2.8 Ω @ 4.5 V), same PG-SOT-23 footprint	Supports higher load currents but lacks dv/dt rating and AEC-Q101 validation	Prefer for industrial 24 V systems requiring >0.2 A continuous current without automotive compliance

Compared with BSS7728NH6327XTSA2, BSS138W offers lower cost but sacrifices 60 V rating and automotive qualification, while DMN2004K delivers higher current capability at the expense of dv/dt ruggedness and automotive validation-making the Infineon part uniquely suited for AEC-Q101-compliant, noise-immune 24 V load switching.

FAQ

Is BSS7728NH6327XTSA2 suitable for high-frequency PWM switching?

Yes - with 2.7 ns turn-on delay, 4.1 ns rise time, and 1.5 nC total gate charge, it supports clean switching up to 500 kHz in low-duty-cycle applications. Its 6 kV/µs dv/dt rating prevents false triggering under fast transients, making it appropriate for PWM-driven LEDs and solenoids in automotive ECUs.

What is the maximum allowable junction temperature during continuous operation?

The absolute maximum junction temperature is +150°C, and the device is characterized for continuous operation up to this limit. At T_A = 70°C, the continuous drain current derates to 0.16 A, and thermal resistance R_thJA is 350 K/W under minimal PCB copper footprint conditions.

Does this MOSFET require a gate resistor for stability?

A gate resistor (typically 10–100 Ω) is recommended to dampen ringing caused by PCB trace inductance and gate capacitance interaction. The datasheet specifies switching times with R_G = 6 Ω, confirming that controlled gate drive improves EMI performance and prevents oscillation in high-speed switching layouts.

Can BSS7728NH6327XTSA2 be used in high-side switching configurations?

It can be used in high-side configurations with appropriate gate drive circuitry (e.g., charge pump or bootstrap IC), though its logic-level V_GS(th) and 60 V rating make it more commonly deployed as a low-side switch. For high-side use, ensure V_GS remains within ±20 V and gate drive voltage exceeds source potential by ≥4.5 V for full enhancement.
