Product details
Overview
TK65E10N1,S1X from Toshiba is a silicon N-channel U-MOSⅧ-H power MOSFET designed for high-current, high-efficiency switching in DC-DC converters and motor drives. It delivers 148 A DC drain current at Tc = 25°C, 4.0 mΩ typ. RDS(ON) at VGS = 10 V, and 100 V VDSS, operating reliably in industrial switching voltage regulators.
For engineers reviewing the TK65E10N1,S1X datasheet, TK65E10N1,S1X pinout, TK65E10N1,S1X application, or TK65E10N1,S1X equivalent, key selection criteria include its low on-resistance, avalanche energy rating (143 mJ), TO-220 package thermal performance (Rth(ch-c) = 0.65°C/W), and gate threshold range (2.0–4.0 V) for robust drive compatibility.
Technical Context
This device uses Toshiba's U-MOSⅧ-H trench-gate process to achieve ultra-low RDS(ON) while maintaining high avalanche ruggedness and fast switching (ton = 44 ns, toff = 85 ns). Its enhancement-mode operation with Vth = 2.0–4.0 V ensures reliable turn-on with standard 10 V gate drivers.
The integrated body diode supports synchronous rectification and freewheeling in buck converters, with measured VDSF = −1.2 V at IDR = 65 A and trr = 76 ns. Thermal design is enabled by direct heatsink mounting via the drain-connected tab (Pin 2), supporting continuous operation up to Tch = 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100 V - Maximum blocking voltage for 48 V input systems with 2× safety margin |
| RDS(ON) (typ.) | 4.0 mΩ at VGS = 10 V - Enables <1 W conduction loss at 50 A, critical for high-efficiency VRMs |
| ID (DC) | 148 A at Tc = 25°C - Supports high-power server/industrial PSU designs with minimal parallel devices |
| EAS | 143 mJ - Withstands single-pulse inductive energy without failure in hard-switched topologies |
| Qg | 81 nC - Optimized for 100–500 kHz operation with moderate gate driver strength requirements |
| Rth(ch-c) | 0.65°C/W - Allows >190 W dissipation with 100°C temperature rise to heatsink |
| Vth | 2.0–4.0 V - Ensures clean turn-on with standard logic-level or PWM controller outputs |
Pinout & Package
TO-220 package (Toshiba designation: 2-10X1A), 3-pin through-hole, 1.93 g typical weight. Drain connected to metal tab for direct heatsinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate | Control terminal requiring ≤81 nC charge; sensitive to ESD - must be protected per JEDEC JS-001 |
| 2 | Drain (heatsink) | Main high-side current path and thermal interface; electrically tied to case - isolation required if mounted to grounded heatsink |
| 3 | Source | Reference node for gate drive and current sensing; connects to low-side switch or ground return path |
Key Features
| Feature | Design Value |
|---|---|
| U-MOSⅧ-H trench structure | Reduces RDS(ON) × Qg figure-of-merit by 35% vs. prior U-MOS generations, improving efficiency at 250–500 kHz |
| Guaranteed avalanche capability | 143 mJ single-pulse rating enables robust operation in non-zero-voltage-switching circuits without snubbers |
| Low gate leakage (±0.1 µA max) | Minimizes standby power loss in always-on control stages and improves long-term reliability under bias stress |
| Enhancement-mode threshold | 2.0–4.0 V window ensures immunity to noise-induced turn-on while remaining compatible with 3.3 V and 5 V logic |
| Integrated body diode | 76 ns reverse recovery time and 150 nC Qrr support synchronous rectification in buck converters up to 300 kHz |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP150N10F7 | RDS(ON) = 3.8 mΩ (typ.), Qg = 92 nC, TO-220FP package (isolated tab) | Lower RDS(ON) but higher gate charge increases switching loss above 250 kHz | Prefer when minimizing conduction loss dominates; avoid if gate drive strength is limited |
| IRF1407PBF | RDS(ON) = 7.5 mΩ (typ.), EAS = 100 mJ, same TO-220 footprint | Higher on-resistance increases conduction loss by ~90% at 50 A; lower avalanche rating limits fault tolerance | Select only for cost-sensitive, low-frequency (<100 kHz), non-critical applications where ruggedness is secondary |
Compared with STP150N10F7 and IRF1407PBF, the TK65E10N1,S1X offers superior balance of low RDS(ON), moderate Qg, and high EAS, making it optimal for high-efficiency, high-reliability 100–500 kHz switching applications where thermal management and fault survival are critical.

FAQ
What is the maximum continuous drain current rating for TK65E10N1,S1X?
The TK65E10N1,S1X is rated for 148 A DC drain current at case temperature Tc = 25°C. This rating assumes proper heatsinking and derates to 65 A at Tc = 100°C per the Safe Operating Area curve. The package limit is 100 A, so actual design current must respect both silicon and mechanical constraints. Always verify thermal design using Rth(ch-c) = 0.65°C/W.
Does TK65E10N1,S1X support avalanche operation, and what is its rated energy?
Yes, the TK65E10N1,S1X is fully rated for single-pulse avalanche operation with EAS = 143 mJ at Tch = 25°C. This is validated per JEDEC JESD24-11 test conditions (VDD = 80 V, L = 26.1 µH, IAR = 65 A). Repeated avalanche stress is not guaranteed - use only for infrequent fault events in hard-switched topologies.
What is the gate threshold voltage range for TK65E10N1,S1X, and how does it affect drive requirements?
The TK65E10N1,S1X has a gate threshold voltage Vth of 2.0–4.0 V (measured at VDS = 10 V, ID = 1.0 mA). This wide range ensures reliable turn-on with 5 V or 10 V gate drivers while preventing accidental turn-on from noise below 2.0 V. For full enhancement, VGS ≥ 10 V is required to achieve the specified 4.0 mΩ RDS(ON).
Can TK65E10N1,S1X be used in synchronous rectification applications?
Yes, the TK65E10N1,S1X integrates a fast, low-loss body diode with trr = 76 ns and Qrr = 150 nC, making it suitable for synchronous rectification in buck converters up to 300 kHz. Its VDSF = −1.2 V at IDR = 65 A provides lower forward drop than discrete Schottky diodes in high-current, low-VOUT designs.
What thermal resistance values apply to TK65E10N1,S1X, and how are they measured?
The TK65E10N1,S1X specifies Rth(ch-c) = 0.65°C/W (max) from channel to case, measured with the drain tab directly attached to a heatsink. Rth(ch-a) = 83.3°C/W (max) is for free-air operation - not practical for high-power use. For system design, use Rth(ch-c) plus heatsink resistance to calculate total thermal path to ambient.
