Product details

Overview

SPP15N65C3 from Infineon Technologies is a 650 V, 15 A CoolMOS™ C3 superjunction power MOSFET in PG-TO220-3 package, featuring 0.25 Ω typical R_DS(on) at 10 V_GS, 63 nC total gate charge, and 460 mJ single-pulse avalanche energy - optimized for high-efficiency AC-DC adapters and offline SMPS primary-side switching.

For engineers reviewing the SPP15N65C3 datasheet, SPP15N65C3 pinout, SPP15N65C3 application, or SPP15N65C3 equivalent, key selection criteria include its extreme dv/dt ruggedness (up to 50 V/ns), JEDEC-qualified reliability for notebook adapters, low conduction and switching losses, and robust body diode with 420 ns reverse recovery time.

Technical Context

This 650 V superjunction MOSFET employs charge-compensation technology to achieve significantly lower R_DS(on) × Q_g figure-of-merit than planar devices, enabling higher power density in flyback and LLC resonant converters. Its 0.8 K/W junction-to-case thermal resistance supports high-current operation at T_C = 100 °C with 9.4 A continuous drain current.

The device integrates a fast-recovery body diode (t_rr = 420 ns, Q_rr = 8 µC) and is rated for repetitive avalanche (E_AR = 5.0 mJ, I_AR = 5 A) under controlled conditions, making it suitable for hard-switched topologies requiring intrinsic overvoltage clamping capability.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	650 V - Withstands full mains rectified voltage (e.g., 375 V DC + margin) in universal-input offline converters.
R_DS(on), max	0.28 Ω at T_j = 25 °C - Enables low conduction loss at 9.4 A continuous current; rises to 0.68 Ω at 150 °C.
Q_g, typ	63 nC - Reduces gate drive power and enables efficient operation with standard 10 V gate drivers.
E_AS	460 mJ (I_D = 3 A, V_DD = 50 V) - Provides single-pulse avalanche robustness during transient overvoltage events.
dv/dt rating	50 V/ns - Ensures reliable operation under fast voltage transients without spurious turn-on.
t_rr	420 ns - Limits diode reverse recovery loss and EMI generation in discontinuous conduction mode (DCM) flyback.
R_thJC	0.8 K/W - Supports thermal design with heatsink interface; allows 156 W power dissipation at T_C = 25 °C.

Pinout & Package

Supplied in PG-TO220-3 package: isolated mounting base (drain-connected tab), three leads in standard TO-220 footprint. Mounting hole accommodates M3 screw; lead pitch 2.54 mm.

Pin/Terminal	Circuit Role	Design Meaning
Lead 1 (left)	Gate (G)	High-impedance control terminal; requires <100 nA leakage current and 3–3.9 V threshold for turn-on.
Lead 2 (center)	Drain (D)	High-voltage power terminal; electrically connected to metal tab; must be insulated from heatsink unless referenced to same potential.
Lead 3 (right)	Source (S)	Power return path and gate reference node; carries full load current and defines local ground for gate driver.

Key Features

Feature	Design Value
Low gate charge (Q_g)	63 nC enables faster switching with reduced driver stress and lower gate-drive power loss.
Extreme dv/dt ruggedness	Rated to 50 V/ns - prevents false triggering during fast voltage transitions in high-frequency SMPS.
High peak current capability	45 A pulsed drain current supports surge handling during startup and overload conditions.
JEDEC-qualified reliability	Complies with J-STD-20/JESD22 for temperature cycling, humidity, and solderability - validated for notebook adapter lifetime requirements.
Robust body diode	420 ns t_rr, 32 A I_rrm, and 8 µC Q_rr reduce recovery-related losses and EMI in quasi-resonant designs.

Applications

LED Driver Power Stage

Use Scenario: Primary-side switch in 65 W universal-input flyback converter operating at 65–130 kHz.

IC Role / Device Role / Timing Role: High-voltage power switch controlling energy transfer via transformer primary winding; gated by PWM controller.

Use Value: Low R_DS(on) and Q_g reduce conduction and switching losses, enabling >90% efficiency and compact heatsink design.

Use Scenario: Primary-side switch in isolated constant-current LED driver for commercial lighting (20–100 W).

IC Role / Device Role / Timing Role: Main power switch regulating input energy into transformer; operates in DCM or QR mode.

Use Value: Fast body diode recovery minimizes dead-time loss and improves light-output stability under dimming.

Industrial SMPS

Server PSU Front-End

Use Scenario: PFC boost switch in active clamp forward or two-switch forward converter for 200–500 W industrial power supplies.

IC Role / Device Role / Timing Role: High-efficiency main switch handling high peak currents and repetitive avalanche stress.

Use Value: 460 mJ E_AS and 5.0 mJ E_AR ensure reliable operation during line surges and output short-circuit events.

Use Scenario: Primary-side switch in high-density 80 PLUS Titanium server PSU using LLC resonant topology.

IC Role / Device Role / Timing Role: Resonant power switch operating near zero-voltage switching (ZVS) boundary.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage superjunction MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPP65R190C7	650 V, 0.19 Ω R_DS(on), 49 nC Q_g, newer CoolMOS™ C7 generation with improved E_oss and lower gate resistance.	Better efficiency at higher frequencies (>150 kHz); requires updated gate drive layout due to faster switching.	Preferred for new designs targeting highest efficiency; not drop-in due to different SOA and gate drive sensitivity.
STP15N65M2	650 V, 0.32 Ω R_DS(on), 72 nC Q_g, MDmesh™ M2 technology with higher R_thJC (1.0 K/W).	Higher conduction loss and thermal resistance; less dv/dt rugged (35 V/ns).	Acceptable for cost-sensitive, lower-frequency (<80 kHz) designs where thermal margin exists.

Compared with IPP65R190C7 and STP15N65M2, the SPP15N65C3 offers balanced trade-offs: lower Q_g than ST's part and superior avalanche robustness versus C7, making it ideal for legacy adapter upgrades and industrial SMPS where proven reliability outweighs marginal efficiency gains.

FAQ

Is SPP15N65C3 RoHS compliant and lead-free?

Yes, the SPP15N65C3 features Pb-free lead plating and complies fully with RoHS Directive 2011/65/EU. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and is qualified for wave soldering at 260 °C for 10 seconds at 1.6 mm from case.

What is the maximum continuous drain current at 100 °C case temperature?

The maximum continuous drain current is 9.4 A at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This value accounts for thermal derating due to increased R_DS(on) and reduced safe operating area at elevated temperatures.

Can SPP15N65C3 replace older CoolMOS™ C2 devices in existing designs?

Yes - the SPP15N65C3 is a direct upgrade from C2-series parts (e.g., SPW20N60C2) with identical pinout, improved R_DS(on), lower Q_g, and enhanced dv/dt ruggedness. No PCB or gate driver changes are required for most flyback and forward converter implementations.

Does the integrated body diode support synchronous rectification?

No - the body diode is not optimized for synchronous rectification. It serves as an intrinsic freewheeling path during switching transitions but lacks the low V_SD and ultra-fast t_rr required for SR control. External Schottky or MOSFET-based synchronous rectifiers are recommended for that function.
