Product details
Overview
BSS7728NH6327XTSA1 from Infineon Technologies is an N-channel enhancement-mode logic-level SIPMOS small-signal MOSFET with 60 V VDS, 5 Ω RDS(on) at VGS = 4.5 V, and 0.2 A continuous drain current, designed for low-power switching in space-constrained consumer and industrial control circuits.
For engineers reviewing the BSS7728NH6327XTSA1 datasheet, BSS7728NH6327XTSA1 pinout, BSS7728NH6327XTSA1 application, or BSS7728NH6327XTSA1 equivalent, key selection criteria include logic-level gate drive compatibility (VGS(th) = 1.3–2.3 V), dv/dt ruggedness (6 kV/µs), and AEC-Q101 qualification for automotive-adjacent reliability.
Technical Context
This MOSFET operates in enhancement mode with a threshold voltage range of 1.3–2.3 V, enabling direct interface with 3.3 V and 5 V microcontroller GPIOs without level-shifting. Its 60 V breakdown rating supports operation across 24 V industrial bus and 12 V automotive subsystems.
The device integrates a monolithic body diode with 0.84–1.2 V forward voltage and 11.5–17.5 ns reverse recovery time, supporting synchronous rectification and flyback snubbing in low-duty-cycle DC-DC stages. Thermal resistance RthJA is 350 K/W at minimal footprint, limiting continuous power dissipation to 0.36 W at TA = 25 °C.

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 VDS (50 V), higher RDS(on) (3.5 Ω @ 10 V), smaller Qg (0.6 nC) | Not AEC-Q101 qualified; unsuitable for automotive-adjacent thermal or reliability requirements | Select when cost sensitivity outweighs 60 V margin and automotive qualification needs |
| DMN2004LK-7 (Diodes Inc.) | Higher ID (0.35 A), lower RDS(on) (2.8 Ω @ 4.5 V), same SOT-23 package | Lacks dv/dt rating and AEC-Q101 validation; body diode trr >20 ns | Prefer for higher-current 3.3 V-switched loads where transient immunity is secondary |
Compared with BSS7728NH6327XTSA1, BSS138W offers lower gate charge but sacrifices voltage margin and qualification; DMN2004LK-7 delivers higher current capability but lacks documented dv/dt robustness and automotive validation-making the Infineon part optimal for reliability-critical, logic-driven 24 V switching.

FAQ
Is BSS7728NH6327XTSA1 suitable for 3.3 V microcontroller GPIO direct drive?
Yes. With a gate threshold voltage of 1.3–2.3 V and guaranteed turn-on at VGS = 4.5 V, it fully activates using standard 3.3 V logic outputs. RDS(on) remains below 7.5 Ω under those conditions, ensuring low conduction loss in typical low-current switching roles.
What is the maximum safe operating voltage for continuous DC operation?
The absolute maximum VDS is 60 V, but continuous DC operation should be limited to ≤48 V to maintain margin against transients and ensure long-term reliability per the SOA curve on page 4 of the datasheet, especially above 70 °C ambient.
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 using RG = 6 Ω, confirming that external resistance improves EMI performance and prevents oscillation during fast edges.
Can BSS7728NH6327XTSA1 replace BSS138 in existing designs?
It can functionally replace BSS138 in most 3.3 V-driven low-current switches, offering higher VDS (60 V vs. 50 V) and AEC-Q101 qualification. However, RDS(on) is higher at 4.5 V (4.3–7.5 Ω vs. ~5 Ω for BSS138), so verify voltage drop and thermal rise under actual load conditions.
