Product details
Overview
FS10KMJ-2#B01 from Renesas Electronics is an N-channel power MOSFET in TO-220FN package, rated for 100 V drain-source voltage, 10 A continuous drain current, and 0.19 Ω typical on-resistance at VGS = 10 V. It integrates a fast-recovery body diode (95 ns) and supports high-speed switching in motor control, lamp drivers, solenoid actuation, and DC-DC converters.
For engineers reviewing the FS10KMJ-2#B01 datasheet, FS10KMJ-2#B01 pinout, FS10KMJ-2#B01 application, or FS10KMJ-2#B01 equivalent, key selection criteria include its 2000 V isolation rating, 1.0 V gate threshold voltage, thermal resistance of 1.5 °C/W (ch-to-case), avalanche-rated pulsed drain current (10 A), and suitability for industrial-grade switching loads requiring robust SOA and fast turn-off.
Technical Context
This MOSFET employs planar vertical DMOS structure with optimized channel geometry to achieve low rDS(on) while maintaining rugged avalanche capability. Its gate threshold voltage (1.0 V min) enables compatibility with 4 V logic-level drive, and the integrated fast-recovery diode reduces external component count in flyback and freewheeling topologies.
The device operates within –55 °C to +150 °C channel temperature range and features a maximum safe operating area (SOA) validated up to 100 V × 10 A under pulse conditions. Thermal design relies on its 1.5 °C/W ch-to-case resistance and TO-220FN's exposed drain tab for direct heatsink mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100 V - Maximum blocking voltage before avalanche; defines upper limit for bus voltage in DC-DC or motor drive stages. |
| rDS(on) (typ) | 0.19 Ω @ VGS = 10 V - Determines conduction loss at 10 A: ~19 W dissipation if continuously on; critical for thermal sizing. |
| ID (cont) | 10 A @ Tc = 25 °C - Continuous current rating assuming case temperature maintained at 25 °C; derates linearly above 25 °C per curve. |
| trr | 95 ns - Reverse recovery time of integrated body diode; impacts switching loss and EMI in hard-switched inductive circuits. |
| Viso | 2000 V AC - Isolation voltage between drain (case) and internal circuitry; enables use in reinforced insulation systems per IEC 60747-17. |
| Rth(ch-c) | 1.5 °C/W - Thermal resistance from channel to case; used with heatsink Rth(c-s) to calculate junction temperature rise. |
| VGS(th) | 1.0–1.5 V - Gate threshold range ensures reliable turn-on with 3.3 V or 5 V microcontroller GPIO without level-shifting. |
Pinout & Package
FS10KMJ-2#B01 uses the TO-220FN package - a 3-pin, through-hole variant with full-molded body and exposed drain tab on the rear surface for mechanical mounting and thermal conduction. The tab is electrically connected to the drain terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control input | Receives gate drive signal; requires <10 nC total gate charge for full enhancement; sensitive to ESD (±20 V max rating). |
| 2 (Drain) | High-side switch node | Connected to TO-220FN metal tab; carries main load current and must be isolated from heatsink unless using insulating pad. |
| 3 (Source) | Return path / reference | Serves as common return for gate drive and load; source inductance directly affects switching speed and ringing. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Turns fully on with 4 V gate voltage (rDS(on) ≤ 0.21 Ω), enabling direct interface with 3.3 V/5 V MCUs without driver ICs. |
| Integrated fast-recovery diode | 95 ns trr reduces reverse recovery loss and eliminates need for external antiparallel diode in buck or H-bridge freewheel paths. |
| Avalanche-rated operation | Rated for repetitive unclamped inductive switching (UIS) with IDA = 10 A pulsed - supports robustness in relay/snubberless designs. |
| 2000 V isolation | Enables use in Class II insulated power supplies and industrial controls where creepage/clearance requirements exceed 8 mm. |
| TO-220FN thermal performance | 1.5 °C/W ch-to-case resistance allows >20 W continuous dissipation with modest heatsinking - suitable for space-constrained 10 A loads. |

FAQ
What is the maximum continuous drain current rating for FS10KMJ-2#B01?
The FS10KMJ-2#B01 is rated for 10 A continuous drain current at case temperature Tc = 25 °C. This rating decreases linearly with rising case temperature - for example, to approximately 6.7 A at Tc = 100 °C - as defined in the power derating curve. Always verify actual Tc under operating conditions when designing thermal management for FS10KMJ-2#B01.
Does FS10KMJ-2#B01 have a built-in body diode, and what is its reverse recovery time?
Yes, FS10KMJ-2#B01 integrates a fast-recovery N-channel body diode with a typical reverse recovery time (trr) of 95 ns, measured at IS = 10 A and di/dt = –100 A/µs. This diode enables self-contained freewheeling in inductive switching applications and eliminates the need for an external antiparallel diode in many DC-DC and motor drive configurations using FS10KMJ-2#B01.
