Product details

Overview

BSS7728NL6327HTSA1 from Infineon Technologies is an N-channel enhancement-mode logic-level SIPMOS™ small-signal MOSFET with 60 V V_DS, 5 Ω R_DS(on) at V_GS = 4.5 V, and 0.2 A continuous drain current; used in low-power load switching, LED drivers, and level-shifted gate control circuits.

For engineers reviewing the BSS7728NL6327HTSA1 datasheet, BSS7728NL6327HTSA1 pinout, BSS7728NL6327HTSA1 application, or BSS7728NL6327HTSA1 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 SOT-23 package thermal resistance (R_thJA = 350 K/W).

Technical Context

This device operates as a single N-channel power switch optimized for low-voltage logic-driven applications. Its enhancement-mode behavior requires positive gate bias to conduct, and its rated dv/dt immunity enables reliable operation in inductive switching environments without spurious turn-on.

The MOSFET features integrated 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 compact DC-DC converters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - maximum blocking voltage before avalanche conduction begins
R_DS(on) @ V_GS = 4.5 V	4.3–7.5 Ω - on-resistance defining conduction loss in 3.3 V–5 V logic-controlled switches
I_D (continuous)	0.2 A @ T_A = 25 °C - usable current under standard PCB footprint conditions
V_GS(th)	1.3–2.3 V - gate threshold enabling direct drive from 1.8 V/3.3 V microcontrollers
dv/dt rating	6 kV/µs - immunity to false triggering during fast voltage transients in motor or relay loads
C_iss	37–56 pF - input capacitance affecting gate drive strength and switching speed
P_tot	0.36 W @ T_A = 25 °C - thermal limit dictating derating above ambient temperature

Pinout & Package

Package: PG-SOT-23 (JEDEC TO-236AB), surface-mount, lead-free, tape-and-reel (L6327: 3000 pcs/reel).

Pin/Terminal	Circuit Role	Design Meaning

Pin 2 (Source)	Reference node	Common return path for drain current; tied to system ground or floating reference
Pin 3 (Drain)	Power output terminal	Connects to load or supply rail; carries switched current up to 0.2 A continuous

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) ≤ 2.3 V enables direct interface with 1.8 V/3.3 V I/O without level-shifting
dv/dt ruggedness	6 kV/µs rating prevents parasitic turn-on in inductive switching applications
Low gate charge	Q_g = 1–1.5 nC minimizes driver power and speeds up switching transitions
Integrated body diode	Reverse recovery time trr = 11.5–17.5 ns supports efficient freewheeling in buck/flyback topologies

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	R_DS(on) = 3.5 Ω @ V_GS = 10 V; lower V_DS (50 V); higher C_iss (60 pF)	Not rated for 60 V systems; better suited for signal switching than power switching	Select when lower on-resistance at 10 V drive is prioritized over voltage headroom
DMN2004K-7	R_DS(on) = 2.7 Ω @ V_GS = 4.5 V; higher I_D (0.35 A); same SOT-23 package	Higher current handling supports more demanding loads but increases gate charge (Q_g = 2.1 nC)	Select when >0.2 A continuous current or lower R_DS(on) at 4.5 V is required

Compared with BSS7728NL6327HTSA1, BSS138W-7-F offers lower R_DS(on) at 10 V but sacrifices 60 V rating and dv/dt robustness; DMN2004K-7 delivers superior conduction performance at 4.5 V with higher thermal capacity, albeit at increased gate drive demand.

FAQ

Is BSS7728NL6327HTSA1 suitable for 1.8 V microcontroller gate drive?

Yes. With a typical gate threshold voltage of 1.9 V and maximum of 2.3 V, it reliably turns on using 1.8 V logic outputs under light load conditions. However, R_DS(on) rises significantly below V_GS = 2.5 V, so full 0.2 A current capability requires ≥3.3 V drive.

What is the maximum safe operating voltage for continuous DC blocking?

The absolute maximum V_DS is 60 V, but the recommended continuous operating voltage is ≤50 V to maintain margin against transients and temperature-induced drift. At T_j = 150 °C, V(BR)_DSS degrades to ~54 V per characterization data.

Does this MOSFET require external gate resistor for ESD protection?

No external gate resistor is required solely for ESD protection-the device meets HBM Class 2 (≥2 kV) per JEDEC JESD22-A114. However, a 10–100 Ω series gate resistor is recommended to dampen ringing and reduce EMI in switching applications.

Can the body diode be used for reverse polarity protection?

No. The integrated body diode conducts from source to drain (anode at source), making it unsuitable for reverse polarity protection. For that function, a dedicated Schottky or PMOS-based solution is required to block reverse current flow.
