Product details

Overview

SSM6K819R,LXHF from Toshiba Electronic Devices & Storage Corporation is a silicon N-channel MOSFET (U-MOS-H) designed for high-speed power switching in compact DC-DC converters and load switches. It delivers R_DS(ON) = 25.8 mΩ (typ.) at V_GS = 4.5 V, supports 100 V drain-source voltage, and handles 10 A DC drain current in TSOP6F package.

For engineers reviewing the SSM6K819R,LXHF datasheet, SSM6K819R,LXHF pinout, SSM6K819R,LXHF application, or SSM6K819R,LXHF equivalent, this device is especially relevant when selecting AEC-Q101-qualified discrete MOSFETs for automotive-grade power management with low gate drive voltage compatibility and verified avalanche ruggedness.

Technical Context

The SSM6K819R,LXHF integrates six parallel N-channel U-MOS-H cells in a single TSOP6F package, enabling high-current capability without external paralleling. Its 4.5-V gate drive threshold and low R_DS(ON) support direct interfacing with 3.3-V/5-V logic controllers and microcontrollers.

It features guaranteed single-pulse avalanche energy of 12.3 mJ and channel temperature rating up to 175 °C, making it suitable for transient-overload conditions in automotive body electronics and industrial power supplies where thermal robustness is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	100 V - Supports 48-V automotive and industrial bus systems with margin against transients.
R_DS(ON) @ 4.5 V	25.8 mΩ (typ.) - Enables efficient 10-A switching with ≤260 mW conduction loss at rated current.
I_D (DC)	10 A - Delivers full-rated current in thermally constrained layouts using standard FR4 PCB copper area.
E_AS	12.3 mJ - Withstands inductive turn-off surges in relay drivers and motor control without clamping diodes.
Q_g	8.5 nC (typ.) - Allows fast switching with moderate gate driver strength (e.g., TC4427 or similar).
R_th(ch-a)	83 °C/W - Requires ≥645 mm² Cu pad on FR4 for safe operation at full DC current.
V_th	1.5–2.5 V - Ensures reliable turn-on with 3.3-V logic while avoiding spurious activation from noise.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN6016LFG-7	60 V V_DSS, 16.5 mΩ @ 4.5 V, SOT-23-6 package, non-AEC-Q101	Limited to ≤60 V systems; lacks automotive qualification and avalanche rating	Preferred for cost-sensitive 5-V logic-controlled consumer power switches where 100 V rating is unnecessary.
IPB057N10N5ATMA1	100 V V_DSS, 5.7 mΩ @ 10 V, TO-263 package, AEC-Q101, higher gate charge (42 nC)	Requires 10-V gate drive; larger footprint and higher drive power demand	Selected when ultra-low R_DS(ON) justifies larger package and gate driver redesign in high-current automotive inverters.

Compared with DMN6016LFG-7 and IPB057N10N5ATMA1, the SSM6K819R,LXHF uniquely balances 100 V rating, 4.5-V drive compatibility, AEC-Q101 compliance, and compact TSOP6F packaging-making it optimal for space-constrained, automotive-qualified 10-A switching where gate drive simplicity and thermal efficiency are prioritized.

FAQ

What is the maximum continuous drain current for SSM6K819R,LXHF at 85°C ambient?

The SSM6K819R,LXHF supports 10 A DC drain current at T_a = 25°C with specified FR4 board conditions. At 85°C ambient, derating applies: using R_th(ch-a) = 83°C/W and T_ch(max) = 175°C, the practical continuous current drops to approximately 6.5 A. Always verify thermal design with actual board layout and airflow in the final application before committing to SSM6K819R,LXHF.

Is SSM6K819R,LXHF pin-compatible with other TSOP6F-packaged MOSFETs?

No-SSM6K819R,LXHF has a unique 4-drain/1-gate/1-source pin assignment (pins 1,2,5,6 = Drain; pin 3 = Gate; pin 4 = Source). Other TSOP6F MOSFETs may differ in pinout, such as dual-channel or logic-level variants. Always confirm pin mapping using the official Toshiba SSM6K819R,LXHF datasheet before PCB layout or replacement.

Does SSM6K819R,LXHF include an integrated body diode, and what is its forward voltage?

Yes, the SSM6K819R,LXHF includes a parasitic body diode inherent to its N-channel MOSFET structure. Its typical forward voltage (V_DSF) is 0.88 V at I_DR = 10 A and V_GS = 0 V, with a maximum of 1.5 V. This diode supports freewheeling in inductive loads but is not optimized for continuous conduction-external Schottky diodes are recommended for high-frequency synchronous rectification.

What gate resistor value is recommended for driving SSM6K819R,LXHF in a 100-kHz switching application?

For 100-kHz operation, a 10 Ω to 22 Ω gate resistor balances switching speed and EMI. With Q_g = 8.5 nC and typical gate driver output impedance, this range achieves ~50–100 ns rise/fall times-well within the SSM6K819R,LXHF's 27 ns/8 ns specs. Lower values increase dV/dt and risk ringing; higher values slow switching and raise conduction losses. Thermal testing with actual SSM6K819R,LXHF layout is advised.

Can SSM6K819R,LXHF be used in high-side configuration with bootstrap gate drive?

Yes-the SSM6K819R,LXHF is suitable for high-side N-channel switching using bootstrap gate drive, provided V_GS remains within ±20 V and the bootstrap capacitor sustains ≥4.5 V during conduction. Its 100 V V_DSS and 175 °C channel rating support common high-side applications like BLDC pre-drivers and automotive lamp control. Ensure dead-time control prevents shoot-through when paired with low-side switches.
