Product details

Overview

SPI15N60C3HKSA1 from Infineon Technologies is a 650 V, 15 A, N-channel enhancement-mode power MOSFET in TO-262-3 package, featuring 0.3 Ω R_DS(on) at V_GS = 10 V and 25 °C, 45 nC total gate charge, and optimized for hard-switched SMPS in industrial AC-DC adapters and UPS systems.

For engineers reviewing the SPI15N60C3HKSA1 datasheet, SPI15N60C3HKSA1 pinout, SPI15N60C3HKSA1 application, or SPI15N60C3HKSA1 equivalent, key selection criteria include breakdown voltage margin, conduction loss at 15 A DC, gate drive compatibility with 10 V logic, and thermal performance in TO-262 surface-mount layouts.

Technical Context

This MOSFET employs Infineon's CoolMOS™ C3 technology, delivering reduced specific on-resistance (R_DS(on) × A) and improved E_oss (290 nJ) versus prior generations. Its superjunction structure enables high-voltage blocking with low conduction losses.

The device supports unclamped inductive switching (UIS) up to 100 mJ at T_j = 25 °C and features avalanche-rated ruggedness. Gate threshold voltage is specified at 3.0–5.0 V, ensuring reliable turn-on with standard 5 V or 10 V drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	650 V - Sustains full mains input (e.g., 380 V DC bus + 100 % surge) in offline SMPS without derating.
I_D (continuous)	15 A @ T_c = 25 °C - Supports 200–300 W continuous output in flyback or PFC stages with forced-air cooling.
R_DS(on)	0.3 Ω max @ V_GS = 10 V - Limits conduction loss to ≤67.5 W at 15 A, enabling compact heatsink design.
Q_g	45 nC - Requires ~0.45 µC gate drive energy per switch cycle; compatible with common 1 A peak gate drivers.
E_oss	290 nJ @ V_DS = 400 V - Reduces turn-off loss in high-frequency operation (>65 kHz) compared to C2 generation.
t_rr	100 ns - Enables clean commutation in diode-recovery-sensitive topologies like LLC resonant converters.

Pinout & Package

Supplied in TO-262-3 (IPAK) package: isolated tab, straight lead form, surface-mount compatible with through-hole reflow. Thermal resistance R_thJC = 0.5 K/W.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	High-voltage power output node	Electrically connected to metal tab; must be mounted to heatsink with insulating pad or isolated mounting hardware.
Source	Power return / reference node	Low-side current sensing point; ties directly to ground plane or shunt resistor in buck/PFC configurations.
Gate	Control input	High-impedance MOS control terminal; requires <100 Ω series gate resistor to damp ringing and limit dV/dt-induced shoot-through.

Key Features

Feature	Design Value
Optimized superjunction cell pitch	Enables 650 V rating with R_DS(on) 30 % lower than predecessor C2 devices at same die size.
Avalanche-rated (UIS)	Guaranteed 100 mJ single-pulse energy handling without failure-critical for PFC overcurrent events.
Reduced E_oss	290 nJ enables >100 kHz operation with minimal increase in switching loss versus 65 kHz baseline.
Enhanced dv/dt ruggedness	Rated for 4.5 V/ns - suppresses false turn-on during high-slew-rate transients in bridge-leg configurations.

Applications

Industrial AC-DC Adapters

Uninterruptible Power Supplies (UPS)

Use Scenario: 300 W open-frame power supply converting 85–264 V AC to 12 V/25 A DC for factory automation controllers.

IC Role / Device Role / Timing Role: Primary-side switching transistor in continuous-conduction-mode (CCM) PFC boost stage.

Use Value: 0.3 Ω R_DS(on) reduces conduction loss by 2.1 W versus 0.42 Ω alternative, improving full-load efficiency from 92.1 % to 93.4 %.

Use Scenario: Online double-conversion UPS with 1 kVA output, requiring high-efficiency 400 V DC bus generation.

IC Role / Device Role / Timing Role: Main inverter switch in H-bridge output stage operating at 16 kHz PWM.

Use Value: 100 ns t_rr prevents cross-conduction losses during dead-time transitions, reducing thermal stress on gate drivers.

Server Power Supplies

IC Role / Device Role / Timing Role: High-side switch in each PFC leg, driven by dedicated gate driver ICs.

Use Value: 45 nC Q_g allows use of cost-effective dual-channel 1 A drivers (e.g., Infineon 1EDN7512B), avoiding need for higher-current alternatives.

Use Scenario: 3 kW variable-frequency drive for HVAC compressors, operating from 380 V three-phase mains.

IC Role / Device Role / Timing Role: Upper-leg IGBT co-packaged MOSFET in active front-end rectifier stage.

Use Value: Avalanche rating ensures survival during line-voltage spikes (e.g., 1.5 kV transient), eliminating need for external snubbers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP15N60DM6	R_DS(on) = 0.32 Ω, Q_g = 42 nC, E_oss = 310 nJ	Lower UIS rating (75 mJ); less robust under short-circuit conditions	Prefer SPI15N60C3HKSA1 where PFC fault immunity is critical.
IXTH15N60L2	R_DS(on) = 0.34 Ω, Q_g = 58 nC, no UIS rating	Higher gate drive demand; unsuitable for fast-recovery or avalanche-limited designs	Choose SPI15N60C3HKSA1 when designing for 100 kHz+ operation with tight thermal budgets.

Compared with STP15N60DM6 and IXTH15N60L2, SPI15N60C3HKSA1 delivers superior avalanche ruggedness and lower E_oss, making it optimal for high-reliability industrial PFC and UPS inverters where transient immunity and high-frequency efficiency are prioritized.

FAQ

What is the maximum junction temperature for SPI15N60C3HKSA1?

The absolute maximum junction temperature is 150 °C, with derated continuous drain current above 25 °C case temperature. At T_c = 100 °C, I_D is limited to 9.5 A. Thermal design must maintain T_j ≤ 150 °C under worst-case load and ambient conditions to ensure reliability.

Is SPI15N60C3HKSA1 suitable for zero-voltage switching (ZVS) topologies?

Yes - its low E_oss (290 nJ) and fast t_rr (100 ns) support efficient ZVS in LLC resonant converters operating up to 300 kHz. The device's soft-recovery behavior minimizes voltage overshoot during resonant turn-off, reducing stress on clamp components.

Does SPI15N60C3HKSA1 require a negative gate voltage for turn-off?

No - it is a standard enhancement-mode MOSFET with V_GS(th) = 3.0–5.0 V. Turn-off is achieved by pulling gate to source (0 V); applying negative voltage is unnecessary and not recommended per datasheet limits (V_GS min = −20 V).

Can SPI15N60C3HKSA1 replace older CoolMOS™ C2 devices in existing designs?

Yes - it is a direct drop-in replacement for SPI15N60C2 with identical pinout, package, and voltage/current ratings. Key improvements include 15 % lower R_DS(on), 20 % lower E_oss, and enhanced UIS capability, enabling immediate efficiency gains without layout changes.
