Product details

Overview

BSL205NH6327XTSA1 from Infineon Technologies is a dual N-channel enhancement-mode MOSFET in PG-TSOP6 package, rated for 20 V V_DS, 2.5 A continuous drain current (T_A = 25 °C), and 50 mΩ R_DS(on) at V_GS = 4.5 V. It features Super Logic-level gate drive (2.5 V rated), AEC-Q101 qualification, and avalanche energy rating of 10.8 mJ.

For engineers reviewing the BSL205NH6327XTSA1 datasheet, BSL205NH6327XTSA1 pinout, BSL205NH6327XTSA1 application, or BSL205NH6327XTSA1 equivalent, key selection criteria include logic-level compatibility with 2.5 V microcontrollers, dual-channel integration for space-constrained load switching, and automotive-grade reliability under transient stress conditions.

Technical Context

This dual MOSFET integrates two identical N-channel silicon devices in a single TSOP6 package, sharing common source terminals per channel. Its gate threshold voltage (0.6–1.2 V) and low R_DS(on) enable efficient switching at 2.5 V logic levels, while the 10.8 mJ single-pulse avalanche rating supports robust operation during inductive load turn-off.

The device exhibits C_iss = 419 pF, C_oss = 152 pF, and Q_g = 3.2 nC at V_GS = 4.5 V, supporting fast switching (t_r = 2.9 ns, t_f = 2.4 ns) with minimal gate drive power. Its reverse diode has V_SD = 1.1 V at I_F = 2.5 A and t_rr = 10 ns, suitable for synchronous rectification and flyback recovery.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	20 V - Supports 12 V automotive and industrial bus systems with margin against transients.
R_DS(on) @ 4.5 V	50 mΩ - Enables ≤125 mW conduction loss at 2.5 A, reducing thermal footprint on FR4 PCBs.
I_D continuous	2.5 A @ T_A = 25 °C - Sufficient for dual-channel LED drivers or motor H-bridge half-bridges.
V_GS(th)	0.6–1.2 V - Ensures reliable turn-on with 2.5 V GPIOs without level-shifting circuitry.
E_AS	10.8 mJ - Withstands inductive kickback in solenoid or relay driving without external snubbers.
Q_g	3.2 nC - Allows full switching with <1 µs gate drive time using standard 10 mA MCU outputs.
t_rr	10 ns - Minimizes reverse recovery losses in high-frequency DC-DC converters.

Pinout & Package

3	Drain 1	High-side or low-side switching node for first channel; rated 20 V/2.5 A.
4	Source 2	Common return path for second N-channel channel; internally bonded to pin 1.
5	Gate 2	Independent control input for second MOSFET; enables dual synchronous switching.
6	Drain 2	Isolated switching node for second channel; electrically separate from Drain 1.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual N-channel logic-level MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2053UVT-7	R_DS(on) = 42 mΩ @ 4.5 V; smaller X1-DFN2020-6 package; no AEC-Q101 rating.	Suitable for consumer portables but not automotive temperature or reliability requirements.	Select when size is critical and AEC-Q101 is not mandated.
SI2302DS-T1-GE3	Single-channel only; R_DS(on) = 60 mΩ @ 4.5 V; SOT-23 package; no avalanche rating.	Requires two devices and extra PCB area; lacks pulse energy handling for inductive loads.	Choose only for non-automotive, low-energy switching where cost outweighs integration.

Compared with DMN2053UVT-7 and SI2302DS-T1-GE3, BSL205NH6327XTSA1 uniquely delivers dual-channel integration, AEC-Q101 compliance, and 10.8 mJ avalanche capability in a thermally optimized TSOP6 package-making it the only option for space-constrained automotive body electronics requiring field reliability.

FAQ

What is the maximum junction temperature and thermal resistance of BSL205NH6327XTSA1?

The absolute maximum junction temperature is 150 °C. Thermal resistance from junction to ambient (R_thJA) is 250 K/W on a minimal 40 mm² FR4 PCB with 1 mm wide, 70 µm thick copper traces on both sides. This value assumes natural convection and no heatsink-designers must derate current above 70 °C ambient.

Does BSL205NH6327XTSA1 support parallel operation of its two channels?

No-the two N-channel MOSFETs share no internal connection between drains or gates; they are fully isolated. Each channel must be driven independently with separate gate signals and current paths. Parallel use of both channels for a single load is not supported due to mismatched R_DS(on) and thermal coupling effects.

Can BSL205NH6327XTSA1 replace discrete 2N7002-type transistors in existing designs?

Yes, provided layout accommodates the TSOP6 footprint and gate drive remains at ≥2.5 V. Its lower R_DS(on) (50 mΩ vs. typical 2N7002's 3 Ω) and dual integration reduce conduction loss and board area, but pinout differs-direct drop-in replacement requires PCB revision to match pin 1–6 mapping.

Is the integrated body diode suitable for reverse polarity protection?

No-the intrinsic body diode conducts forward from source to drain, making it unsuitable for reverse polarity protection. For that function, an external P-channel MOSFET or dedicated protection IC is required. The diode is optimized for inductive flyback recovery, not blocking reverse voltage.
