Product details
Overview
SSM3J140TU,LXHF from Toshiba Electronic Devices & Storage Corporation is a silicon P-channel MOSFET in UFM package, designed for low-voltage power management switches. It delivers RDS(ON) = 25.8 mΩ (max) at VGS = −4.5 V, supports −4.4 A DC drain current, and operates with 1.5-V gate drive capability-enabling efficient load switching in space-constrained automotive and industrial control modules.
For engineers reviewing the SSM3J140TU,LXHF datasheet, SSM3J140TU,LXHF pinout, SSM3J140TU,LXHF application, or SSM3J140TU,LXHF equivalent, key selection criteria include its AEC-Q101 qualification, −20 V VDSS, low-threshold gate drive compatibility, and thermal performance on FR4 boards with 645 mm² copper pad.
Technical Context
This P-channel enhancement-mode MOSFET uses Toshiba's U-MOS process to achieve low RDS(ON) across low gate voltages (−1.5 V to −4.5 V), supporting direct interface with 1.8-V and 3.3-V logic controllers. Its gate threshold voltage (Vth) ranges from −0.3 V (min) to −1.0 V (max), ensuring reliable turn-on under weak-drive conditions while maintaining robust off-state blocking up to −20 V.
The device features integrated body diode with VDSF = 0.83 V (typ.) at 4.4 A, and exhibits Ciss = 1800 pF (typ.), Coss = 205 pF (typ.), enabling predictable switching behavior in high-frequency load-switching applications with controlled dV/dt and EMI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −20 V - Supports rail-to-rail operation in 12-V automotive and 5-V industrial systems without breakdown risk. |
| RDS(ON) @ VGS = −4.5 V | 25.8 mΩ (max) - Enables ≤115 mW conduction loss at 4.4 A, reducing thermal stress on small PCBs. |
| ID (DC) | −4.4 A - Rated continuous current for sustained load switching in power rails and battery protection circuits. |
| Vth | −0.3 to −1.0 V - Ensures turn-on with 1.5-V logic-level signals, eliminating need for level shifters in ultra-low-voltage control. |
| PD (FR4, 645 mm²) | 500 mW - Specifies maximum steady-state power dissipation on standard PCB layout per Toshiba test condition. |
| Ciss | 1800 pF (typ.) - Determines gate drive strength requirement; compatible with low-current GPIO or buffer drivers. |
| VGS Range | −8/+6 V - Allows safe gate biasing with common supply rails and protects against overvoltage transients. |

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 |
|---|---|---|---|
| DMN2011UFG-7 | RDS(ON) = 28 mΩ (max) @ −4.5 V; VDSS = −20 V; SOT-23 package; not AEC-Q101 qualified. | Suitable for commercial-grade portable electronics but lacks automotive qualification and thermal derating data. | Select when cost sensitivity outweighs automotive compliance and board space permits larger SOT-23 footprint. |
| AO3415 | RDS(ON) = 42 mΩ (max) @ −4.5 V; VDSS = −20 V; SOT-23; AEC-Q101 qualified only in specific tape-and-reel variants. | Higher conduction loss limits use to ≤2.5 A continuous loads; less stable Vth drift over temperature than SSM3J140TU,LXHF. | Prefer for legacy designs where pinout compatibility with existing SOT-23 layouts is mandatory and lower current is acceptable. |

FAQ
What is the gate threshold voltage range for SSM3J140TU,LXHF?
The SSM3J140TU,LXHF has a gate threshold voltage (Vth) ranging from −0.3 V (minimum) to −1.0 V (maximum) at ID = −1 mA. This low-threshold characteristic enables reliable turn-on with 1.5-V logic-level gate drive, making the SSM3J140TU,LXHF especially suitable for direct interface with ultra-low-voltage microcontrollers and battery-powered systems where minimizing gate drive overhead is critical.
Is SSM3J140TU,LXHF qualified for automotive applications?
Yes, SSM3J140TU,LXHF is AEC-Q101 qualified, confirming its suitability for automotive electronic systems. The qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge (ESD) per JESD22-A114. This makes the SSM3J140TU,LXHF appropriate for use in automotive door modules, body control units, and other non-safety-critical vehicle subsystems where robustness under thermal and electrical stress is required.
What is the maximum continuous drain current for SSM3J140TU,LXHF?
The SSM3J140TU,LXHF supports a maximum continuous drain current (ID) of −4.4 A at Ta = 25 °C, measured under standard FR4 board conditions (25.4 mm × 25.4 mm × 1.6 mm with 645 mm² copper pad). Derating is required above 25 °C ambient; the device's channel temperature must not exceed 150 °C. For sustained operation near rated current, thermal design using the specified PCB layout is essential to maintain reliability.
Does SSM3J140TU,LXHF include an integrated body diode?
Yes, SSM3J140TU,LXHF includes a monolithically integrated body diode with forward voltage (VDSF) of 0.83 V (typical) at ID = 4.4 A and VGS = 0 V. This diode supports freewheeling current in inductive load applications such as solenoid drivers and motor controls, eliminating the need for an external flyback diode in many designs and simplifying bill-of-materials for compact power switches.
What package type does SSM3J140TU,LXHF use, and what are its dimensions?
SSM3J140TU,LXHF uses the UFM (Ultra Small Flat Mount) package-a 3-pin, leadless, surface-mount plastic package measuring 2.0 mm × 2.1 mm × 0.9 mm (typical) with a weight of 6.6 mg. Its compact size and low profile make the SSM3J140TU,LXHF ideal for high-density PCB layouts in automotive ECUs, wearables, and portable medical devices where board space and height constraints are critical.
