Product details

Overview

BSH205G2VL from Nexperia is a P-channel enhancement-mode Trench MOSFET in SOT23 (TO-236AB) package, rated for -20 V drain-source voltage, 120–170 mΩ R_DS(on) at V_GS = -4.5 V and I_D = -2 A, and qualified to AEC-Q101 for automotive use. It serves as a high-side load switch or relay driver in space-constrained DC power control circuits.

For engineers reviewing the BSH205G2VL datasheet, BSH205G2VL pinout, BSH205G2VL application, or BSH205G2VL equivalent, key selection criteria include its low 0.45–0.95 V gate threshold, 890 mW power dissipation on FR4 PCB, and verified performance in 12 V automotive body electronics switching.

Technical Context

This device uses Trench MOSFET technology to achieve low R_DS(on) and enhanced thermal performance in a 3-pin SOT23 footprint. Its P-channel architecture enables simple high-side switching without level-shifting circuitry, and its AEC-Q101 qualification confirms robustness under automotive temperature cycling (-55 °C to +150 °C junction).

The MOSFET exhibits stable sub-threshold conduction down to V_GS = -0.45 V and maintains R_DS(on) < 240 mΩ up to T_j = 150 °C, supporting reliable operation in thermally demanding environments such as engine bay modules or LED lighting drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-20 V - Maximum reverse drain-source blocking capability for 12 V automotive systems with load-dump margin.
R_DS(on)	120–170 mΩ @ V_GS = -4.5 V, I_D = -2 A, T_j = 25 °C - Enables ≤340 mW conduction loss at 2 A, critical for thermally constrained PCB layouts.
V_GS(th)	-0.45 to -0.95 V - Ensures turn-on with standard 3.3 V or 5 V logic-level gate drive, eliminating need for external level shifters.
P_tot	890 mW @ T_amb = 25 °C on FR4, 6 cm² drain pad - Supports continuous 2 A switching without heatsink in compact consumer or automotive modules.
Q_G(tot)	3.7–6.5 nC - Low gate charge enables fast switching (t_r = 14 ns, t_f = 16 ns) with minimal driver power consumption.
I_D	-2.3 A pulsed (t ≤ 5 s), -1.2 A continuous @ T_amb = 100 °C - Defines safe operating area for intermittent high-current loads like solenoids or motors.

Pinout & Package

Package: TO-236AB (SOT23), surface-mount plastic package with 3 leads, 1.4 mm × 2.9 mm footprint, single-sided copper FR4 mounting pad (6 cm² recommended for thermal performance).

Pin/Terminal	Circuit Role	Design Meaning
1	G (Gate)	Control terminal accepting logic-level negative voltage to modulate channel conduction; requires no external pull-up for high-side default-off behavior.
2	S (Source)	Reference node tied to system rail (e.g., battery +12 V); connects to load return path and defines V_GS reference for gate drive.
3	D (Drain)	Power output terminal connected to load; thermally coupled to PCB copper pad to dissipate up to 890 mW in ambient conditions.

Key Features

Feature	Design Value
Low threshold voltage	V_GS(th) down to -0.45 V ensures reliable turn-on with 3.3 V microcontroller GPIOs in battery-powered systems.
Trench MOSFET technology	Enables 120 mΩ R_DS(on) in SOT23, reducing conduction losses by >30% versus planar P-MOSFETs of same size.
AEC-Q101 qualification	Validated for automotive applications including temperature cycling, humidity bias, and mechanical shock per JESD22 standards.
Enhanced power dissipation	890 mW rating on standard FR4 PCB eliminates need for thermal vias or oversized pads in cost-sensitive designs.

Applications

Automotive Body Control Module

Use Scenario: Replacing electromechanical relays in PLC I/O modules for dry-contact simulation or solenoid actuation.

IC Role / Device Role / Timing Role: Solid-state high-side switch delivering up to 2.3 A pulsed current to relay coils with controlled turn-on/turn-off timing.

Use Value: 8 A peak drain current (t_p ≤ 10 µs) handles relay coil inrush; integrated source-drain diode provides flyback path without external components.

Use Scenario: Enabling/disabling VBUS power path in USB-C receptacles for host devices requiring programmable power routing.

Use Value: -20 V V_DS rating accommodates USB PD 20 V max; SOT23 footprint fits tight board space near connector; low leakage (<1 µA) prevents standby current drain.

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel MOSFET switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMG2305UVT-7	R_DS(on) = 45 mΩ @ V_GS = -4.5 V but rated only to -20 V; higher gate charge (10.5 nC); SOT23-3 package.	Better conduction efficiency at high current, but slower switching and less suitable for thermally limited 2 A continuous loads.	Select when lower R_DS(on) dominates over thermal budget and gate drive strength is sufficient.
SI2301DS-T1-BE3	R_DS(on) = 115 mΩ @ V_GS = -4.5 V; not AEC-Q101 qualified; P_tot = 710 mW on same PCB layout.	Lower cost for non-automotive applications; reduced thermal margin limits sustained 2 A operation above 60 °C ambient.	Select for industrial or consumer products where automotive qualification is unnecessary and cost sensitivity is high.

Compared with DMG2305UVT-7 and SI2301DS-T1-BE3, BSH205G2VL delivers balanced performance: AEC-Q101 compliance and 890 mW thermal capability make it optimal for automotive and industrial high-reliability 2 A switching, while its 3.7–6.5 nC gate charge supports efficient medium-frequency PWM control without overloading logic drivers.

FAQ

What is the maximum continuous drain current for BSH205G2VL at 100 °C ambient temperature?

The maximum continuous drain current is -1.2 A at T_amb = 100 °C, as specified in Table 5 (Limiting values). This derating reflects thermal constraints of the SOT23 package on standard FR4 PCB; operation above this current requires active cooling or larger copper area.

Does BSH205G2VL include an integrated body diode, and what is its forward voltage?

Yes, it features an inherent source-drain body diode with V_SD = -0.8 to -1.2 V at I_S = -0.8 A and T_j = 25 °C (Table 10). This diode enables freewheeling in inductive loads like relay coils without external components.

Can BSH205G2VL be used with 3.3 V logic-level gate drive?

Yes - its gate-source threshold voltage range of -0.45 V to -0.95 V guarantees turn-on with 3.3 V logic (V_GS = -3.3 V), delivering full R_DS(on) performance well below its -4.5 V test condition.

Is the SOT23 footprint of BSH205G2VL compatible with standard reflow soldering processes?

Yes - Nexperia provides validated reflow soldering footprints (Fig. 19) with 0.6 mm solder land width and 0.5 mm spacing, fully compliant with IPC-7351B Class L for automated assembly and thermal reliability on FR4 boards.
