Product details

Overview

BSS87L6327HTSA1 from Infineon Technologies is an N-channel enhancement-mode logic-level SIPMOS small-signal transistor in SOT-89 package, rated for 240 V drain-source breakdown voltage, 0.26 A continuous drain current at 25°C, and 3.9–6 Ω R_DS(on) at V_GS = 10 V. It is AEC-Q101 qualified and used in automotive load switching and industrial DC-DC converter high-side control.

For engineers reviewing the BSS87L6327HTSA1 datasheet, BSS87L6327HTSA1 pinout, BSS87L6327HTSA1 application, or BSS87L6327HTSA1 equivalent, key selection criteria include dv/dt immunity (6 kV/µs), gate threshold voltage range (0.8–1.8 V), reverse diode recovery time (53.6–80.4 ns), and halogen-free RoHS-compliant construction.

Technical Context

This device operates as a logic-level N-channel MOSFET with low gate charge (Q_g = 3.7–5.5 nC) and fast switching dynamics: turn-on delay <5.5 ns, rise time <5.2 ns, and fall time <41 ns. Its dv/dt rating enables robust operation in inductive load switching without spurious turn-on.

The integrated body diode supports synchronous rectification and flyback energy recovery, with V_SD = 0.82–1.2 V at I_S = 0.26 A and reverse recovery charge Q_rr = 101–152 nC - critical for minimizing switching losses in high-frequency SMPS designs.

Key Specifications

R_DS(on) @ 10 V	3.9–6 Ω - enables low conduction loss at logic-level gate drive
I_D cont @ 25°C	0.26 A - suitable for signal-level and low-power load switching
dv/dt immunity	6 kV/µs - prevents false triggering in noisy inductive environments
Q_g	3.7–5.5 nC - reduces gate driver power requirement and switching transition time
V_GS(th)	0.8–1.8 V - ensures reliable turn-on with 3.3 V or 5 V microcontroller outputs

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
BSS84L6327HTSA1	P-channel counterpart; V_DS = −50 V, R_DS(on) = 10–14 Ω @ V_GS = −5 V	Used in low-side switching where source is grounded; not interchangeable in high-side configurations	Select only when topology requires P-channel high-side or complementary drive
DMN2004LK3-7	N-channel, V_DS = 20 V, R_DS(on) = 2.4 Ω @ V_GS = 4.5 V, SOT-23 package	Lower voltage rating limits use to ≤12 V systems; smaller footprint but higher thermal resistance	Prefer for space-constrained 3.3 V/5 V logic interfaces where 240 V capability is unnecessary

Compared with BSS87L6327HTSA1, BSS84L6327HTSA1 offers complementary polarity but lower voltage capability, while DMN2004LK3-7 trades off voltage headroom and thermal performance for miniaturization - making the BSS87 optimal for 24 V–200 V logic-driven switching where reliability and dv/dt immunity are critical.

FAQ

Is BSS87L6327HTSA1 suitable for high-side switching in 24 V automotive systems?

Yes. With 240 V V_DS, 6 kV/µs dv/dt rating, and AEC-Q101 qualification, it reliably switches 24 V inductive loads such as solenoids and lamps. Its logic-level V_GS(th) (0.8–1.8 V) ensures full enhancement using standard MCU GPIOs without gate drivers.

What is the maximum junction temperature and how does R_DS(on) vary with temperature?

The absolute maximum junction temperature is +150°C. R_DS(on) increases with temperature: at T_j = 100°C and V_GS = 10 V, typical R_DS(on) rises to ~18 Ω - a 3× increase over room-temperature value - requiring derating in thermally constrained layouts.

Does BSS87L6327HTSA1 include an integrated body diode, and what are its key parameters?

Yes, it features a monolithic body diode with forward voltage V_SD = 0.82–1.2 V at I_S = 0.26 A and reverse recovery time t_rr = 53.6–80.4 ns. Q_rr = 101–152 nC enables predictable recovery behavior in flyback and synchronous rectifier topologies.

Can BSS87L6327HTSA1 be used in place of BSS138 in 3.3 V logic circuits?

No. While both are N-channel MOSFETs, BSS138 has V_DS = 50 V and R_DS(on) ≈ 3.5 Ω at 2.5 V V_GS, whereas BSS87L6327HTSA1 is optimized for higher voltage (240 V) and exhibits higher R_DS(on) below 4.5 V. Use BSS87 only where 200+ V capability and dv/dt immunity are required.
