Product details

Overview

BSS131L6327HTSA1 from Infineon Technologies is an N-channel enhancement-mode SIPMOS® small-signal MOSFET rated for 240 V V_DS, 0.11 A continuous drain current at 25 °C, and 14 Ω max R_DS(on) at V_GS = 10 V; designed for logic-level gate drive (V_GS(th) = 0.8–1.8 V), dv/dt ruggedness (6 kV/µs), and automotive-grade reliability per AEC-Q101 in SOT-23 package.

For engineers reviewing the BSS131L6327HTSA1 datasheet, BSS131L6327HTSA1 pinout, BSS131L6327HTSA1 application, or BSS131L6327HTSA1 equivalent, this part supports low-power switching in space-constrained automotive body electronics, LED drivers, and load management circuits where logic-compatible gate drive and high-voltage blocking are required.

Technical Context

This MOSFET operates in enhancement mode with a threshold voltage range of 0.8–1.8 V, enabling direct interface with 3.3 V and 5 V microcontrollers without level-shifting. Its dv/dt rating of 6 kV/µs ensures robustness against voltage transients in inductive load switching.

Thermal resistance R_thJA is 350 K/W (minimal footprint), limiting power dissipation to 0.36 W at 25 °C ambient; dynamic parameters include C_iss = 77 pF typ, Q_g = 3.1 nC max, and t_r = 4.6 ns typ - supporting fast, low-loss switching up to ~1 MHz in low-current applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	240 V - blocks up to 240 V DC or peak AC in relay replacement and load switch circuits
R_DS(on) max	14 Ω @ V_GS = 10 V - delivers ≤140 mW conduction loss at 0.1 A, suitable for <100 mW load control
I_D cont.	0.11 A @ T_A = 25 °C - supports low-current switching in sensors, LEDs, and bias networks
V_GS(th)	0.8–1.8 V - fully enhances with standard logic-level outputs (e.g., STM32 GPIO, PIC I/O)
dv/dt rating	6 kV/µs - withstands fast voltage transients in automotive 12 V systems with inductive loads
Q_g max	3.1 nC - enables efficient gate driving with <1 µA average gate current at 100 kHz
T_j range	−55 to +150 °C - qualified for under-hood automotive use per AEC-Q101

Pinout & Package

Package: PG-SOT-23 (JEDEC TO-236AB), surface-mount, 3-pin, Pb-free, tape-and-reel (marking: L6327).

3 (Drain)	High-side or low-side switched output terminal	Rated for 240 V blocking; connects to load or supply rail depending on topology

Key Features

Feature	Design Value

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
DMN2004LK-7	R_DS(on) = 12 Ω max @ V_GS = 4.5 V; lower threshold (0.5–1.2 V); same SOT-23 package	Better suited for 3.3 V-only systems; slightly higher leakage (I_DSS = 1 µA)	Select when gate drive voltage is limited to ≤4.5 V and lower R_DS(on) is critical
BS170	V_DS = 60 V; R_DS(on) = 5 Ω @ V_GS = 10 V; non-AEC-Q101; TO-92 package	Not suitable for automotive or >60 V applications; lacks dv/dt rating and high-temp reliability	Only consider for non-automotive, low-voltage prototyping where cost outweighs qualification

Compared with DMN2004LK-7 and BS170, BSS131L6327HTSA1 uniquely combines 240 V blocking, AEC-Q101 qualification, and 6 kV/µs dv/dt immunity - making it the only option validated for under-hood 12 V switching with transient resilience.

FAQ

Is BSS131L6327HTSA1 suitable for 24 V industrial control applications?

Yes. With 240 V V_DS rating, −55 to +150 °C operating range, and AEC-Q101 qualification, it exceeds requirements for 24 V PLC I/O protection and load switching. Its 6 kV/µs dv/dt rating also handles inductive kickback from solenoids and relays without external snubbers.

What is the maximum recommended gate resistor for PWM switching at 100 kHz?

A 10 Ω series gate resistor is recommended for 100 kHz operation. This value balances rise/fall times (t_r/t_f ≈ 4.6/97 ns) and ringing suppression while keeping gate drive current within typical MCU GPIO limits (<20 mA peak).

Does BSS131L6327HTSA1 include an integrated ESD protection diode?

No. It has HBM ESD sensitivity rated Class 1a (≤250 V), meaning external ESD protection (e.g., 100 pF capacitor + 1 kΩ resistor) is advised on gate traces in handling-sensitive environments, especially in automotive assembly lines.

Can this MOSFET replace a BS170 in existing designs?

Only with circuit review. While both are N-channel SOT-23 MOSFETs, BSS131L6327HTSA1 has 4× higher V_DS (240 V vs. 60 V) and higher R_DS(on) (14 Ω vs. 5 Ω). It is not a drop-in replacement unless the original design operates below 60 V and can tolerate higher on-resistance and different threshold behavior.
