SCT4062KRC15 - 1200V 26A 62mΩ SiC MOSFET TO-247-4 | ROHM
MPN: SCT4062KRC15 ✓ Hoạt độngSCT4062KRC15 Tóm tắt
A Silicon Carbide (SiC) MOSFET is a wide-bandgap power transistor built on a SiC epitaxial layer rather than conventional silicon. Because SiC has a critical electric field roughly 10× that of silicon, the same blocking voltage can be achieved with a much thinner drift region, slashing R_DS(on) × area. Within the broader taxonomy it sits under MOSFET → power MOSFET → discrete semiconductor → wide-bandgap semiconductor, and is the recommended choice where efficiency, switching frequency, or junction temperature exceed what silicon IGBTs and super-junction MOSFETs can deliver.
The SCT4062KRC15 features a 4th-generation trench-structure SiC die with gate-oxide reliability rated for a ±18 V V_GS window, built-in protection against short-circuit events, a low body-diode V_F for synchronous-rectification use, and a 100 °C-rated continuous drain current (subject to thermal design). Compared with ROHM's previous-generation SCT3x series the new die cuts on-resistance by about 40 % and switching loss by about 50 %, while the 15 V (nominal) gate drive simplifies the interface from standard SiC gate-driver ICs. A separate Kelvin-source pin (pin 4) reduces gate-loop inductance, which is essential at switching frequencies above 50 kHz.
Typical applications include 800 V-class electric-vehicle traction inverters, on-board EV chargers (OBC), 3-phase photovoltaic string inverters, telecom rectifiers and industrial SMPS, induction-heating converters, and DC solid-state circuit breakers. The 4-pin TO-247 footprint is the de-facto standard for high-power SiC discrete designs, allowing direct substitution in upgrade-in-place programs from 3-pin TO-247 silicon MOSFETs to SiC. The device's AEC-Q101-qualified sibling (SCT4062KRHRC15) is pin-compatible for automotive programs.
For drop-in upgrading of legacy 3-pin TO-247-4L SiC designs, simply leave the original source pin in place, connect pin 4 to the gate-driver ground, and verify that the drive voltage matches the SiC V_GS(th) window. The page synthesizes distributor pricing, parametric alternatives, and practical gate-drive design notes not found in the manufacturer datasheet.

Ghi chú thiết kế
The TO-247-4L Kelvin-source pin (pin 4) MUST be connected to the gate-driver ground reference, not to the power-source bond. This decouples the high di/dt power current from the gate-drive return path and prevents source-inductance-induced V_GS ringing. Estimate: at 100 A/µs di/dt a 5 nH common-source inductance would produce 0.5 V of gate-rail ringing - enough to re-trigger the device into avalanche. Layout the gate-drive loop area under 1 cm² and use a 4-layer PCB with continuous ground plane beneath the TO-247 footprint.
Estimated thermal analysis: at VIN=800 V, VOUT=400 V (half-bridge), and 10 A continuous drain current, the SCT4062KRC15 dissipates approximately 6.2 W (62 mΩ × 10²). With TO-247 junction-to-case thermal resistance of 0.9 °C/W and a typical clip-mount heatsink of 5 °C/W, junction temperature rises 36 °C above the 70 °C heatsink - safe but tight. For 100 % continuous load, use a forced-air or water-cooled heatsink to keep Tj below 150 °C for margin.
Use a Kelvin-source PCB layout: route the gate-driver ground return directly to pin 4 (Kelvin source), while the power-return PCB trace runs separately from pin 3 to the bulk capacitor. Place the gate-driver IC within 5 mm of the TO-247 to minimize gate-loop inductance. Add a 10 Ω gate-source resistor close to the device pins to damp Miller-induced turn-on. A 1 nF to 100 nF decoupling cap between V_GS and the driver ground further reduces high-frequency ringing.
Do not use a standard silicon IGBT gate driver (15 V on / 0 V off) - the off-state voltage is insufficient for SiC. Use a SiC-aware driver that swings -3 to -5 V off to prevent parasitic turn-on at high dV/dt. Do not exceed V_GS of ±18 V (absolute max) - over-voltage on the gate oxide is the most common SiC failure mode. Do not parallel multiple SCT4062KRC15 without gate-source resistors to suppress parasitic oscillation.
