Product details

Overview

SSM3K7002KF,LXHF from Toshiba Electronic Devices & Storage Corporation is a silicon N-channel MOSFET designed for high-speed switching in low-power load control circuits. It features R_DS(ON) = 1.05 Ω (typ.) at V_GS = 10 V, 60 V V_DSS, and AEC-Q101 qualification for automotive-grade reliability. It is commonly used in LED drivers, power management modules, and signal-level switching in compact consumer and industrial electronics.

For engineers reviewing the SSM3K7002KF,LXHF datasheet, SSM3K7002KF,LXHF pinout, SSM3K7002KF,LXHF application, or SSM3K7002KF,LXHF equivalent, key selection criteria include gate threshold voltage (V_th = 1.1–1.75 V), pulsed drain current capability (I_DP = 1.2 A), thermal resistance constraints on FR4 boards, and compatibility with 3.3 V/5 V logic-level drive.

Technical Context

This discrete MOSFET operates in enhancement mode with a single N-channel structure optimized for fast turn-on/turn-off via low gate charge (Q_g = 0.39 nC typ.). Its dynamic characteristics-C_iss = 26 pF, t_r = 3.6 ns, t_f = 5.5 ns-are specified under V_DD = 30 V, I_D = 200 mA, and R_G = 50 Ω conditions, supporting efficient switching in DC-DC converters and PWM-controlled loads.

The device integrates an intrinsic body diode (V_DSF = −0.79 V typ. at I_D = −115 mA) and exhibits channel temperature-limited operation up to 150 °C. Absolute maximum ratings assume specific PCB mounting conditions: 645 mm² copper pad for P_D = 900 mW, or 0.8 mm² × 3 pads for P_D = 270 mW-critical for thermal design validation.

FAQ

What is the gate threshold voltage range for SSM3K7002KF,LXHF?

The SSM3K7002KF,LXHF has a gate threshold voltage (V_th) range of 1.1 V to 1.75 V at I_D = 250 µA. This allows reliable turn-on with common 1.8 V, 3.3 V, and 5 V logic outputs. The typical value is 1.2 V, and variation across temperature is characterized in Fig. 8.6 of the official datasheet. Designers should verify gate drive margin under worst-case V_th and temperature conditions for their specific SSM3K7002KF,LXHF implementation.

Is SSM3K7002KF,LXHF suitable for automotive applications?

Yes, the SSM3K7002KF,LXHF is AEC-Q101 qualified, confirming its suitability for automotive applications such as body electronics, door modules, and infotainment power stages. The qualification applies specifically to the SSM3K7002KF,LXHF orderable part number, as noted in the "Orderable part number" table. Automotive use requires adherence to Toshiba's handling precautions, thermal derating guidelines, and board layout recommendations for reliability.

What is the maximum continuous drain current for SSM3K7002KF,LXHF?

The maximum continuous drain current (I_D) for SSM3K7002KF,LXHF is 400 mA at T_a = 25 °C, assuming proper PCB thermal design. This rating assumes mounting on a 25.4 mm × 25.4 mm × 1.6 mm FR4 board with three 0.8 mm² copper pads. At elevated ambient temperatures or reduced copper area, derating is required per the R_th(ch-a) curves in the datasheet to prevent exceeding the 150 °C channel temperature limit.

Does SSM3K7002KF,LXHF include a body diode, and what is its forward voltage?

Yes, the SSM3K7002KF,LXHF includes an integrated body diode with a typical forward voltage (V_DSF) of −0.79 V at I_D = −115 mA and V_GS = 0 V. This diode supports freewheeling current in inductive loads like relays or small motors. Its performance is pulse-tested and documented in Section 6.5 of the datasheet; designers should account for its reverse recovery behavior in high-frequency switching applications involving the SSM3K7002KF,LXHF.

What package type does SSM3K7002KF,LXHF use, and are there footprint considerations?

The SSM3K7002KF,LXHF uses the S-Mini package (TOSHIBA designation: 2-3F1S), a 3-pin SOT-23 variant with 0.65 mm lead pitch and 12 mg typical weight. Its pinout is Gate–Source–Drain (1–2–3). Footprint considerations include thermal pad clearance, solder mask defined pads per IPC-7351B, and ESD-safe handling during placement. The package is compatible with standard reflow profiles but requires attention to moisture sensitivity level (MSL) per Toshiba's packaging documentation for the SSM3K7002KF,LXHF.
