Product details

Overview

SPP15N65C3HKSA1 from Infineon Technologies is a 650 V, 15 A, N-channel superjunction MOSFET in TO-220-3 package, featuring 340 mΩ R_DS(on) at V_GS = 10 V and 175 °C junction temperature, optimized for high-efficiency switch-mode power supplies in industrial AC-DC adapters and LED drivers.

For engineers reviewing the SPP15N65C3HKSA1 datasheet, SPP15N65C3HKSA1 pinout, SPP15N65C3HKSA1 application, or SPP15N65C3HKSA1 equivalent, key selection criteria include R_DS(on), gate charge (Q_G = 42 nC), E_oss (380 nJ), avalanche ruggedness (E_AS = 490 mJ), and TO-220 thermal performance under continuous conduction mode.

Technical Context

This MOSFET employs Infineon's CoolMOS™ C3 technology, delivering reduced switching losses via low gate charge and optimized output capacitance (C_oss = 450 pF). Its 650 V rating supports universal-input offline SMPS designs with margin for line surges.

The device integrates 100% avalanche-tested ruggedness and features a Kelvin source pin configuration in TO-220-3 to minimize source inductance-critical for high-frequency ZVS and resonant topologies like LLC converters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	650 V - Supports 400 V DC bus with 25% safety margin for surge immunity in global AC mains applications.
I_D (T_C = 25°C)	15 A - Continuous drain current rating enabling 150–200 W power stages without forced air cooling.
R_DS(on) max	340 mΩ @ V_GS = 10 V, T_J = 175°C - Enables low conduction loss in PFC and main switch positions of two-stage PSUs.
Q_G	42 nC - Reduces gate drive power and enables efficient operation at 65–100 kHz in hard-switched flyback and forward converters.
E_oss	380 nJ @ V_DS = 400 V - Low stored output energy improves light-load efficiency and reduces turn-off loss in resonant topologies.
E_AS	490 mJ - Fully rated single-pulse avalanche capability ensures robustness against transient overvoltage during startup or short-circuit events.

Pinout & Package

TO-220-3 package with standard lead frame, isolated tab (drain-connected), and through-hole mounting. Thermal resistance R_thJC = 1.2 K/W enables 15 A operation at T_C ≤ 100°C.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Power return path for load current	Low-inductance connection point; used for Kelvin sensing in high-accuracy gate drive layouts.
Pin 2 (Gate)	Control terminal for channel conduction	High-impedance input requiring <42 nC charge for full enhancement; sensitive to ESD and ringing.
Pin 3 (Drain)	Main high-voltage power terminal	Internally connected to metal tab; must be electrically isolated from heatsink unless referenced to system ground.

Key Features

Feature	Design Value
Superjunction architecture	Enables 650 V breakdown with R_DS(on) × A figure-of-merit < 1.5 Ω·mm² for compact, high-power-density designs.
100% avalanche tested	Guarantees single-pulse E_AS = 490 mJ without derating-eliminates need for external snubbers in cost-sensitive industrial PSUs.
Low Q_G/Q_GD ratio	Reduces Miller-induced shoot-through risk and simplifies gate driver selection for 12 V logic-level control.
Enhanced dV/dt ruggedness	Rated for 4.5 V/ns at 25 °C - maintains reliable operation in fast-switching LLC and phase-shifted full-bridge converters.

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
STP15N65M2	R_DS(on) = 350 mΩ, Q_G = 45 nC, no Kelvin source	Lacks Kelvin source; higher gate drive loss in high-frequency ZVS designs	Preferred where cost sensitivity outweighs 3% efficiency gain and layout complexity is constrained.
IXTH15N65X2	R_DS(on) = 320 mΩ, Q_G = 38 nC, TO-247 package	Larger footprint and higher thermal resistance (R_thJC = 0.85 K/W) requires larger heatsink	Chosen when peak efficiency >93% is mandatory and board space permits TO-247 mounting.

Compared with STP15N65M2 and IXTH15N65X2, SPP15N65C3HKSA1 offers optimal balance of Kelvin-source-enabled layout flexibility, TO-220 thermal manageability, and 42 nC gate drive efficiency-making it ideal for space-constrained 150–200 W industrial power supplies.

FAQ

What is the maximum recommended gate-source voltage for SPP15N65C3HKSA1?

The absolute maximum V_GS is ±20 V per Infineon's official datasheet. Operation above +20 V risks permanent gate oxide damage; typical drive uses +12 V to +15 V for full enhancement with margin. Gate drive circuits must include clamping (e.g., Zener diodes) to prevent overshoot during fast switching transients.

Does SPP15N65C3HKSA1 require a heatsink in 15 A continuous operation?

Yes. At I_D = 15 A and T_A = 50°C, junction temperature exceeds 175°C without heatsinking. With a 50 cm² aluminum heatsink (R_thSA ≈ 10 K/W), T_J remains at ~115°C-within safe operating area. Thermal design must account for R_thJC = 1.2 K/W and interface material resistance.

Can SPP15N65C3HKSA1 replace older CoolMOS™ C2 devices in existing designs?

Yes, with minor layout review. SPP15N65C3HKSA1 has identical pinout and voltage/current ratings but lower Q_G and E_oss. Gate drive strength may need adjustment to avoid excessive dV/dt; snubber networks can often be reduced or removed due to improved switching behavior.

Is the TO-220-3 package of SPP15N65C3HKSA1 electrically isolated?

No-the metal tab is internally connected to the drain terminal. Electrical isolation from the heatsink requires insulating hardware (e.g., silicone pad + shoulder washer) and verification of dielectric strength ≥2.5 kV RMS per IEC 60950-1. Direct mounting to grounded heatsink is only safe if drain is system ground referenced.
