Product details

Overview

SPW17N80C3 from Infineon Technologies is an 800 V, 17 A Cool MOS™ power transistor in TO-247 package, featuring R_DS(on) = 0.29 Ω at 10 V_GS, ultra-low gate charge (Q_g = 91–177 nC), and periodic avalanche rating. It serves as a high-efficiency primary-side switch in offline SMPS, PFC stages, and industrial motor drives operating up to 150 °C junction temperature.

For engineers reviewing the SPW17N80C3 datasheet, SPW17N80C3 pinout, SPW17N80C3 application, or SPW17N80C3 equivalent, key selection criteria include its 50 V/ns dv/dt capability, 670 mJ single-pulse avalanche energy, 0.6 K/W junction-to-case thermal resistance, and body diode reverse recovery charge (Q_rr = 15 µC) for hard-switched topologies.

Technical Context

This N-channel enhancement-mode MOSFET employs Infineon's 3rd-generation Cool MOS™ technology, optimized for reduced conduction and switching losses in high-voltage AC/DC converters. Its low C_iss (2320 pF) and C_oss (1250 pF) enable fast switching with minimal EMI generation under 640 V DC bus conditions.

The device integrates a robust intrinsic body diode rated for 17 A continuous forward current and 550 ns reverse recovery time at 100 A/µs di/dt. Its gate plateau voltage of 6 V supports stable turn-on control across wide temperature ranges, while R_DS(on) exhibits only moderate positive temperature coefficient up to 150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - Supports 650 V AC mains designs with 20% margin for surge and ringing
R_DS(on)	0.29 Ω @ T_j = 25°C - Enables <1.7 W conduction loss at 11 A DC, critical for thermally constrained PFC stages
Q_g	91–177 nC - Reduces gate drive power and allows use of smaller, lower-cost drivers in high-frequency operation
E_AS	670 mJ - Withstands single-pulse inductive energy without failure in flyback or LLC resonant converter startup
dv/dt Rating	50 V/ns - Ensures reliable operation in high-dV/dt environments like phase-cut dimmers and unfiltered rectified inputs
R_thJC	0.6 K/W - Enables direct mounting to heatsink for >200 W continuous power dissipation at T_C = 100°C
Q_rr	15 µC - Limits commutation losses and EMI during body diode conduction in half-bridge ZVS circuits

Pinout & Package

SPW17N80C3 uses the standard 3-pin TO-247 package with drain-connected tab for optimal thermal path. Pin 1 is Gate, Pin 2 is Drain (tab), Pin 3 is Source - consistent with JEDEC TO-247AB mechanical outline and Infineon's P-TO247 marking convention.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives 0–10 V logic-level gate drive; requires <200 nC total charge for full enhancement
Pin 2 (Drain / Tab)	High-voltage power output	Electrically connected to metal tab; must be isolated from heatsink unless system ground referenced
Pin 3 (Source)	Power return and reference	Serves as local ground reference for gate driver; carries full load current and body diode reverse recovery current

Key Features

Feature	Design Value
Ultra-low gate charge	Q_g = 91–177 nC enables 100+ kHz switching with <1 W gate drive loss in 640 V bus applications
Periodic avalanche rated	Rated for repetitive 0.5 mJ avalanche events at 17 A, supporting robust overvoltage protection in unregulated converters
Extreme dv/dt immunity	50 V/ns rating prevents spurious turn-on during fast transients in high-noise industrial environments
Low R_DS(on) temperature coefficient	R_DS(on) increases only ~2.5× from 25°C to 150°C, enabling predictable thermal derating in sealed enclosures
Body diode softness	Reverse recovery time trr = 550 ns with low peak reverse current (I_rrm = 51 A) reduces snubber stress in bridge configurations

LED Streetlight Driver

Telecom Rectifier Module

Use Scenario: Outdoor 200 W constant-current LED driver with universal AC input and passive PFC.

IC Role / Device Role / Timing Role: Boost switch in continuous conduction mode (CCM), operating at 65 kHz with 17 A pulsed drain current.

Use Value: 0.29 Ω R_DS(on) keeps conduction loss below 2.5 W at full load, reducing heatsink size by 35% vs. prior-gen 800 V MOSFETs.

Use Scenario: 48 V telecom rectifier with dual 2 kW modules feeding -48 V DC distribution bus.

IC Role / Device Role / Timing Role: Synchronous rectification switch in LLC resonant secondary side, requiring low C_oss (1250 pF) for zero-voltage switching.

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
STP16N80	R_DS(on) = 0.38 Ω, Q_g = 120 nC, no specified avalanche rating	Lacks periodic avalanche capability; unsuitable for unclamped inductive loads	Prefer SPW17N80C3 where EAS > 500 mJ is required for reliability
IPP60R190C6	600 V rating, R_DS(on) = 0.19 Ω, Q_g = 65 nC, CoolMOS™ C6 generation	Lower voltage rating limits use to 400 V AC systems; higher efficiency at 600 V bus	Select IPP60R190C6 only when system max V_DS ≤ 600 V and switching frequency >150 kHz

Compared with STP16N80 and IPP60R190C6, SPW17N80C3 uniquely balances 800 V blocking, sub-0.3 Ω R_DS(on), and certified avalanche ruggedness-making it the only choice for 800 V hard-switched PFC and industrial UPS designs demanding both efficiency and fault tolerance.

FAQ

What is the maximum recommended gate-source voltage for SPW17N80C3?

The absolute maximum DC gate-source voltage is ±20 V, with ±30 V allowed for AC signals above 1 Hz. Operation beyond ±20 V risks permanent gate oxide damage. For reliable long-term performance, gate drive should be clamped to 10–12 V during normal switching, as the gate threshold voltage is 2.1–3.9 V and plateau occurs near 6 V.

Can SPW17N80C3 replace older 800 V MOSFETs like SPW20N80C3 in existing designs?

Yes-SPW17N80C3 shares identical TO-247 package, pinout, and voltage rating with SPW20N80C3, but offers lower R_DS(on) (0.29 Ω vs. 0.33 Ω) and reduced Q_g. Thermal design may require minor heatsink adjustment due to higher current density, but no PCB layout change is needed.

Is the body diode suitable for synchronous rectification in LLC resonant converters?

No-the body diode has 550 ns reverse recovery time and 15 µC Q_rr, making it unsuitable for high-frequency synchronous rectification. It is designed for freewheeling and clamping roles only. External Schottky or SiC diodes are required for true synchronous rectification above 100 kHz.

What is the safe operating area (SOA) limitation at 100°C case temperature?

At T_C = 100°C, the DC SOA limit is approximately 11 A at 100 V_DS, decreasing to 5 A at 400 V_DS. Pulse SOA supports 17 A up to 1 ms at 25°C case, but must be derated per the transient thermal impedance curve (Z_thJC) when T_C exceeds 25°C.
