Product details

Overview

BSS131E6327 from Infineon Technologies is an N-channel enhancement-mode logic-level SIPMOS® small-signal transistor in PG-SOT-23 package, rated for 240 V V_DS, 14 Ω R_DS(on) max at V_GS = 10 V and I_D = 0.1 A, with 6 kV/µs dv/dt immunity and AEC-Q101 qualification for automotive use.

For engineers reviewing the BSS131E6327 datasheet, BSS131E6327 pinout, BSS131E6327 application, or BSS131E6327 equivalent, this device is selected for low-power switching in space-constrained automotive body electronics, LED drivers, and load-switching circuits where logic-level gate drive and high dv/dt robustness are required.

Technical Context

This transistor operates in enhancement mode with a gate threshold voltage of 0.8–1.8 V, enabling direct drive from 3.3 V or 5 V microcontrollers. Its 240 V breakdown voltage and 6 kV/µs dv/dt rating support reliable operation in inductive load switching environments such as solenoid control and relay drivers.

The integrated body diode exhibits 42.9–64.3 ns reverse recovery time and 22.6–34 nC Q_rr, supporting moderate-frequency commutation. Thermal resistance R_thJA is 350 K/W (minimal footprint), limiting continuous power dissipation to 0.36 W at T_A = 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	240 V - supports switching loads up to 200 V DC with margin for transients
R_DS(on) max	14 Ω at V_GS = 10 V, I_D = 0.1 A - enables <1.4 V drop at 100 mA, suitable for low-loss load switching
I_D continuous	0.11 A at T_A = 25 °C - defines maximum steady-state current in ambient-mounted SOT-23
dv/dt rating	6 kV/µs - ensures immunity to fast voltage transients in automotive and industrial inductive switching
Q_g total	2.1–3.1 nC - determines gate drive energy requirement for ~100 ns switching transitions
t_rr	42.9–64.3 ns - sets minimum dead-time requirements when used in half-bridge configurations
T_j range	−55 to +150 °C - qualified for under-hood automotive applications per AEC-Q101

Pinout & Package

Package: PG-SOT-23 (standard JEDEC TO-236AB), surface-mount, three-terminal plastic package with exposed drain pad for thermal relief.

Pin/Terminal	Circuit Role	Design Meaning
1 (Drain)	Main current-carrying terminal (high-side switch node)	Connected to load supply rail; electrically tied to exposed pad for thermal conduction
2 (Gate)	Control input for channel conduction	Logic-level compatible (V_GS(th) ≤ 1.8 V); requires <3.1 nC charge for full turn-on
3 (Source)	Reference terminal and current return path	Typically grounded in low-side switch configuration; defines V_GS reference for gate drive

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) max = 1.8 V - eliminates need for gate driver IC when interfaced with 3.3 V/5 V MCUs
AEC-Q101 qualified	Qualified for automotive applications including body control modules and lighting systems
High dv/dt immunity	6 kV/µs - prevents false turn-on during fast voltage transients in inductive load switching
Pb-free & RoHS compliant	Pb-free lead plating - meets EU RoHS Directive 2011/65/EU and automotive ELV requirements
Integrated body diode	Reverse recovery time t_rr ≤ 64.3 ns - supports efficient freewheeling in low-frequency PWM loads

Applications

Automotive Body Control

LED Lighting Driver

Use Scenario: Switching 12 V incandescent or LED lamps in door modules and interior lighting.

IC Role / Device Role / Timing Role: Low-side load switch controlled by MCU GPIO with minimal external components.

IC Role / Device Role / Timing Role: High-side or low-side current-path switch modulated at 100–1000 Hz.

Use Value: Low R_DS(on) minimizes power loss (<140 mW at 100 mA); fast t_f (64.5–97 ns) supports clean PWM edges.

Industrial Sensor Interface

Power Supply Sequencing

Use Scenario: Enabling/disabling 24 V sensor power rails in PLC I/O modules.

IC Role / Device Role / Timing Role: Protected load switch with overtemperature and dv/dt immunity.

Use Value: 6 kV/µs dv/dt rating prevents spurious turn-on from EMI; −55 to +150 °C operation covers extended industrial temperature range.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level small-signal switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2004LK-7	R_DS(on) = 3.5 Ω @ V_GS = 4.5 V; higher current rating (0.45 A)	Lower on-resistance suits higher-current loads but requires larger PCB footprint (SOT-26)	Select when >100 mA continuous current or lower conduction loss is required
BS170	V_DS = 60 V; R_DS(on) = 5 Ω @ V_GS = 10 V; not AEC-Q101 qualified	Limited to non-automotive 5–12 V systems; lacks dv/dt immunity and high-temp reliability	Select only for cost-sensitive consumer-grade 3.3/5 V logic switching below 60 V

Compared with DMN2004LK-7 and BS170, BSS131E6327 uniquely balances 240 V capability, AEC-Q101 qualification, and logic-level drive in SOT-23 - making it optimal for automotive 12 V/24 V load switching where space, reliability, and transient immunity are critical.

FAQ

What is the maximum gate-source voltage for BSS131E6327?

The absolute maximum gate-source voltage is ±20 V. Operation beyond this risks permanent gate oxide damage. For reliable logic-level drive, V_GS should be limited to 0–10 V in normal operation, with transient spikes clamped by external Zener protection if needed.

Can BSS131E6327 be used in high-frequency PWM applications?

It supports PWM frequencies up to ~1 MHz in low-duty-cycle, low-current conditions, but its 64.5–97 ns fall time and 2.1–3.1 nC gate charge make it best suited for <100 kHz switching. For >500 kHz, consider devices with lower Q_g and faster t_f.

Is the body diode suitable for continuous freewheeling?

Yes - the integrated body diode supports continuous forward current up to 0.11 A and pulsed current up to 0.43 A. Its 0.81–1.2 V forward voltage at 0.1 A and 42.9–64.3 ns t_rr allow efficient freewheeling in low-frequency inductive loads like solenoids and relays.

Does BSS131E6327 require a gate resistor in typical applications?

A gate resistor (10–100 Ω) is recommended to damp ringing and limit peak gate current during switching. While not strictly required for logic-level drive, it improves EMI performance and prevents oscillation, especially with long PCB traces or high di/dt loads.
