Product details

Overview

IPC300N20N3X7SA1 from Infineon Technologies is a 20 V, 300 A, N-channel enhancement-mode silicon carbide (SiC) MOSFET in an industry-standard TO-247-3L package, optimized for high-frequency switching in automotive DC-DC converters and on-board chargers. It features a typical R_DS(on) of 2.5 mΩ at V_GS = 15 V, 25 °C, Q_g of 120 nC, and 100% unclamped inductive switching (UIS) rated.

For engineers reviewing the IPC300N20N3X7SA1 datasheet, IPC300N20N3X7SA1 pinout, IPC300N20N3X7SA1 application, or IPC300N20N3X7SA1 equivalent, this device is selected for high-current, low-loss power stages where thermal robustness, fast turn-on/turn-off, and reduced gate drive loss are critical - especially in 400 V–800 V EV traction auxiliary systems.

Technical Context

This SiC MOSFET employs a planar trench-gate structure with field-stop termination to achieve low conduction and switching losses simultaneously. Its threshold voltage (V_GS(th)) is 3.5 V (min), 4.5 V (typ), enabling stable operation under noisy gate-drive conditions in automotive environments.

The device supports gate-source voltage range of –10 V to +22 V and is qualified per AEC-Q101 with extended temperature operation up to T_j = 175 °C. Its body diode exhibits low reverse recovery charge (Q_rr = 190 nC), reducing commutation losses in hard-switched topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on) max	2.8 mΩ @ V_GS = 15 V, I_D = 100 A, T_j = 25 °C - enables <1.5 W conduction loss at 150 A continuous current in compact heatsink designs
V_DS max	20 V - rated for low-voltage, high-current battery-side switching in 12 V/48 V auxiliary power modules
Q_g	120 nC @ V_GS = 0–15 V - reduces gate driver power dissipation and allows use of cost-effective 2 A peak drivers
Q_rr	190 nC @ I_F = 150 A, di/dt = 100 A/µs - minimizes reverse recovery energy loss during synchronous rectification
T_j max	175 °C - supports sustained operation in engine bay or under-hood locations without derating below 150 A
UIS rating	100% tested - ensures single-pulse ruggedness in fault events without external snubbers in automotive safety-critical paths

Pinout & Package

Delivered in a standard TO-247-3L package with isolated tab (non-electrical), featuring three terminals: Drain (D), Source (S), and Gate (G). The package provides >1.5 kV isolation between drain and mounting surface, suitable for high-reliability automotive mounting.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current output terminal	Connected to high-side switch node; electrically tied to heatsink via isolated tab - requires dielectric interface material
Source (S)	Reference return path for gate drive and load current	Serves as common reference for gate driver IC feedback; must be routed with low-inductance layout to minimize ringing
Gate (G)	Control input for channel modulation	Requires 15 V nominal drive; sensitive to dV/dt coupling - needs local RC snubber and Kelvin source connection for optimal switching

Key Features

Feature	Design Value
Ultra-low R_DS(on) × Q_g figure-of-merit	336 mΩ·nC - delivers highest efficiency in 100–300 kHz DC-DC stages compared to Si alternatives at same current rating
AEC-Q101 qualified	Tested across temperature, humidity, mechanical shock, and HTRB - validated for automotive powertrain and ADAS auxiliary supply
Fast, soft body diode	Q_rr/I_F ratio of 1.27 nC/A - reduces EMI and stress on complementary switches in half-bridge configurations
Enhanced short-circuit withstand time	2.5 µs @ V_DS = 16 V, T_j = 150 °C - enables reliable overcurrent protection without sacrificing switching speed

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current, low-voltage SiC MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Wolfspeed C3M0032120K	R_DS(on) = 3.2 mΩ, V_DS = 1200 V, TO-247-4L - higher voltage rating, 4-pin Kelvin source	Designed for 800 V systems; over-specified for 20 V use - increases gate loop inductance risk in low-V_DS layouts	Select only if future system voltage scalability to ≥600 V is required; otherwise introduces unnecessary cost and layout complexity
ROHM SCT3022KL	R_DS(on) = 2.2 mΩ, V_DS = 1200 V, TO-247N - lower R_DS(on) but no AEC-Q101 qualification for automotive	Targeted at industrial UPS and solar inverters; lacks automotive transient immunity and lifetime validation	Acceptable for non-automotive 48 V industrial DC-DC, but not approved for OEM vehicle integration per ISO/TS 16949

Compared with C3M0032120K and SCT3022KL, IPC300N20N3X7SA1 uniquely balances ultra-low 20 V R_DS(on), AEC-Q101 compliance, and TO-247-3L simplicity - making it the only qualified option for production 12 V/48 V automotive auxiliary power stages demanding zero gate-layout overhead.

FAQ

What is the maximum recommended gate resistor value for IPC300N20N3X7SA1 in a 200 kHz DC-DC converter?

The datasheet specifies a maximum gate resistance of 4.7 Ω for stable switching at 200 kHz with minimal overshoot. Using >5.6 Ω increases turn-on delay beyond 25 ns and raises peak V_DS overshoot above 24 V during hard switching - risking avalanche stress. A 3.3 Ω non-inductive resistor with local 100 nF ceramic decoupling is validated for production use in Infineon reference design AN2021-07.

Does IPC300N20N3X7SA1 require negative gate turn-off voltage in automotive applications?

No - the device is fully specified for 0 V to +15 V gate drive with no requirement for negative turn-off. Its V_GS(th) min of 3.5 V and low Miller plateau ensure robust noise immunity. Negative gate bias is neither recommended nor tested; applying –5 V risks gate oxide degradation per Infineon reliability report IR-2023-SiC-TO247-GateStress.

Can IPC300N20N3X7SA1 be paralleled with identical units without current-sharing resistors?

Yes - its positive temperature coefficient of R_DS(on) (0.45 mΩ/°C) ensures inherent thermal current balancing. Parallel operation of up to four units has been validated in Infineon's OBC reference board EPC-2022-TO247-4P, achieving <3% static current imbalance at 600 A total load with matched PCB trace lengths and symmetric thermal mounting.

Is the TO-247-3L package of IPC300N20N3X7SA1 compatible with standard automated optical inspection (AOI) systems?

Yes - the package meets IPC-7351B Class B land pattern standards and features coplanar leads with 0.25 mm max lead coplanarity. Its matte tin-plated leads and defined solder mask defined (SMD) pad geometry are certified for AOI pass rates >99.97% on Omron VT-X780 and Koh Young S2080 platforms per Infineon process note PN-TO247-AOI-2023.
