Product details

Overview

BSS138N-E6327 from Infineon Technologies is an N-channel enhancement-mode logic-level SIPMOS® small-signal MOSFET rated for 60 V V_DS, 3.5 Ω R_DS(on) at 4.5 V V_GS, and 0.23 A continuous drain current. It features dv/dt ruggedness (6 kV/µs), AEC-Q101 qualification, and operates across –55 °C to 150 °C junction temperature-used in automotive LED control, low-side load switching, and power management in space-constrained PCBs.

For engineers reviewing the BSS138N-E6327 datasheet, BSS138N-E6327 pinout, BSS138N-E6327 application, or BSS138N-E6327 equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 0.6–1.4 V), thermal resistance (R_thJA = 350 K/W), reverse diode recovery (t_rr = 9.1–14.5 ns), and SOT-23 footprint suitability for high-density routing.

Technical Context

This discrete MOSFET uses a planar SIPMOS® process optimized for fast switching and robust dv/dt immunity. Its gate threshold voltage (0.6–1.4 V) ensures reliable turn-on with 3.3 V or 5 V logic, while the integrated body diode supports freewheeling in inductive loads.

Designed for automotive-grade reliability, it meets AEC-Q101 stress testing and halogen-free compliance per IEC61249-2-21. The device's low Q_g (1.0–1.4 nC) and C_iss (32–41 pF) enable efficient high-frequency operation up to several MHz in DC-DC and signal-switching applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - maximum blocking voltage before avalanche; suitable for 24 V automotive and 48 V industrial bus interfaces
R_DS(on) @ 4.5 V	3.5 Ω max - enables low conduction loss at logic-level gate drive; supports ≤0.23 A continuous load without heatsink
I_D continuous	0.23 A @ T_A = 25 °C - defines steady-state current capability in minimal-footprint SOT-23 package
dv/dt rating	6 kV/µs - withstands rapid voltage transients common in motor commutation and relay driving
t_rr	9.1–14.5 ns - fast body diode recovery reduces switching losses in synchronous rectification and flyback snubbing
Q_g	1.4 nC max - low total gate charge minimizes driver power and speeds up turn-on/turn-off transitions
R_thJA	350 K/W - thermal resistance limits power dissipation to 0.36 W at ambient; requires careful layout for >100 mW operation

Pinout & Package

Package: PG-SOT-23 (JEDEC TO-236AB), surface-mount, 3-pin plastic package with standard footprint and tape-and-reel delivery (H6327: 3000 units/reel).

3 (Drain)	Power output	Carries switched load current; connected to positive rail or inductive load; exposed pad not present in SOT-23

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) = 0.6–1.4 V ensures full enhancement with 3.3 V microcontroller outputs without level-shifting
AEC-Q101 qualified	Validated for automotive electronics including body control modules and lighting systems under extended temperature and vibration stress
dv/dt ruggedness	6 kV/µs rating prevents false turn-on during high-slew transients in motor drivers and solenoid controls
Halogen-free & RoHS	Complies with IEC61249-2-21 and EU RoHS Directive; Pb-free terminations support lead-free reflow assembly

Applications

Automotive LED Headlamp Switching

Industrial Sensor Power Gating

Use Scenario: Low-side switching of 12 V LED arrays in headlamp modules with PWM dimming up to 20 kHz.

IC Role / Device Role / Timing Role: Discrete N-channel MOSFET acting as controlled current sink; handles repetitive 0.2 A pulses with <10 ns switching transitions.

Use Value: Logic-level gate enables direct MCU GPIO drive; dv/dt immunity prevents misfiring during ignition noise bursts.

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) = 2.8 Ω @ 4.5 V; higher I_D = 0.3 A; same SOT-23 package	Marginally better conduction loss but lower dv/dt rating (not specified); no AEC-Q101 qualification	Select when higher current headroom is needed and automotive qualification is not required.
2N7002K-T1-GE3	R_DS(on) = 3.5 Ω @ 4.5 V; same V_DS = 60 V; lower Q_g = 0.7 nC; no dv/dt or AEC-Q101 spec	Lower gate drive energy but unqualified for automotive; less rugged under voltage transients	Prefer for cost-sensitive consumer designs where transient immunity is not critical.

Compared with DMN2004LK-7 and 2N7002K-T1-GE3, BSS138N-E6327 uniquely combines AEC-Q101 qualification, 6 kV/µs dv/dt rating, and tight V_GS(th) tolerance-making it the only choice for safety-critical automotive load switching where reliability under electrical stress is mandatory.

FAQ

Is BSS138N-E6327 suitable for 3.3 V microcontroller GPIO direct drive?

Yes. With a guaranteed gate threshold voltage range of 0.6–1.4 V and full enhancement at V_GS = 4.5 V, the BSS138N-E6327 reliably switches on using standard 3.3 V CMOS outputs. Its low R_DS(on) (3.5 Ω max at 4.5 V) ensures minimal voltage drop and power loss at typical load currents below 0.2 A.

Does BSS138N-E6327 include an integrated body diode, and what are its specifications?

Yes. It integrates a monolithic body diode rated for 0.23 A continuous forward current and 0.92 A pulsed current. Diode forward voltage is 0.83–1.2 V at I_F = 0.23 A and T_j = 25 °C, with reverse recovery time of 9.1–14.5 ns under specified test conditions (V_R = 30 V, di_F/dt = 100 A/µs).

What is the maximum safe operating temperature for continuous use?

The junction temperature must not exceed 150 °C. At ambient temperatures above 70 °C, derating applies: continuous drain current drops from 0.23 A at 25 °C to 0.18 A at 70 °C. Thermal design must account for R_thJA = 350 K/W and power dissipation limits (0.36 W at 25 °C ambient).

Can BSS138N-E6327 replace BSS138 in existing designs?

Yes, with verification of layout and stress conditions. BSS138N-E6327 offers improved dv/dt immunity (6 kV/µs vs. unspecified for legacy BSS138), tighter V_GS(th) distribution, and AEC-Q101 qualification. Electrical parameters are compatible, but the enhanced ruggedness may reduce need for external snubbers in noisy environments.
