Product details

Overview

SIPC26N80C3 from Infineon Technologies is a 800 V, 26 A, 140 mΩ (typ.) N-channel superjunction MOSFET in TO-220FP package, optimized for high-efficiency SMPS in industrial and telecom power supplies with hard-switching operation.

For engineers reviewing the SIPC26N80C3 datasheet, SIPC26N80C3 pinout, SIPC26N80C3 application, or SIPC26N80C3 equivalent, key selection criteria include R_DS(on) at V_GS = 10 V, gate charge (Q_G = 53 nC), E_oss (1.9 µJ), and avalanche ruggedness (E_AS = 470 mJ) under repetitive unclamped inductive switching.

Technical Context

This CoolMOS C3 device employs charge compensation technology to achieve low conduction and switching losses simultaneously. Its 800 V breakdown voltage supports universal AC input designs, while the reduced Q_G/Q_GD ratio enables fast turn-on/turn-off with low drive loss.

The MOSFET features fully avalanche-rated operation up to T_j = 150 °C and is qualified per JEDEC JESD47. It integrates an integrated ESD protection diode (HBM Class 1C) and exhibits low gate threshold voltage (V_GS(th) = 3.5 V min) for reliable gate drive compatibility.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - supports 400 V DC bus with 100 % margin for surge and ripple in offline SMPS
I_D (T_C = 25 °C)	26 A - continuous drain current rating at heatsink-mounted condition
R_DS(on) (max)	170 mΩ - worst-case on-resistance at V_GS = 10 V and T_j = 100 °C
Q_G	53 nC - total gate charge determining driver strength requirement and switching speed
E_oss	1.9 µJ - output capacitance energy affecting zero-voltage switching feasibility
E_AS	470 mJ - single-pulse avalanche energy capability enabling robustness in inductive load transients

Pinout & Package

Supplied in TO-220FP (full-pack) package with isolated flange, featuring three terminals: Drain (tab), Source (pin 1), Gate (pin 2). The metal tab is electrically connected to the Drain and thermally coupled to the die for efficient heat transfer.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	High-side power switch node	Electrically tied to heatsink; requires isolation washer in non-isolated mounting
Source (Pin 1)	Reference node for gate drive and current sensing	Low-inductance return path for switching current; connects to ground or low-side switch source
Gate (Pin 2)	Control terminal for channel conduction	Requires 10 V minimum drive for full enhancement; sensitive to ESD and ringing

Key Features

Feature	Design Value
Reduced Q_G/Q_GD ratio	Enables faster switching with lower gate driver power loss and reduced Miller-induced shoot-through risk
Low E_oss	Supports higher-frequency operation in resonant topologies without excessive capacitive loss
100 % avalanche tested	Guarantees reliability under unclamped inductive switching stress in PFC and LLC stages
JEDEC JESD47 qualified	Validated for long-term operation in industrial temperature range (−40 °C to 150 °C junction)

Use Value: 800 V rating provides headroom for 600 V DC link with overvoltage margin during regenerative braking.

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
STP26NM80	R_DS(on) = 180 mΩ (max), Q_G = 65 nC, no avalanche rating	Lacks guaranteed E_AS testing; less suitable for unclamped inductive loads	Prefer SIPC26N80C3 where avalanche robustness is required in PFC or flyback snubber circuits
IPP60R190C7	650 V rating, R_DS(on) = 190 mΩ, lower Q_G (42 nC), newer CoolMOS C7 process	Not rated for 800 V systems; limited to 380 V DC bus max	Select SIPC26N80C3 for universal-input 800 V designs; choose IPP60R190C7 only if system voltage ≤ 400 V DC

Compared with STP26NM80 and IPP60R190C7, the SIPC26N80C3 uniquely combines 800 V rating, guaranteed avalanche capability, and balanced Q_G/R_DS(on) for high-reliability industrial SMPS where voltage margin and transient robustness are critical.

FAQ

What is the maximum recommended gate resistor value for SIPC26N80C3 in a 200 kHz LLC resonant converter?

A 10 Ω gate resistor is recommended for optimal EMI and switching loss trade-off at 200 kHz. Lower values (≤5 Ω) increase dV/dt and risk parasitic turn-on; higher values (>22 Ω) extend turn-off time, raising switching loss and thermal stress. Layout-dependent gate loop inductance must remain below 10 nH to avoid oscillation.

Does SIPC26N80C3 require a negative gate turn-off voltage?

No. SIPC26N80C3 operates reliably with 0 V turn-off and +10 V to +15 V turn-on. A negative gate voltage is not required due to its elevated V_GS(th) (3.5–5.5 V) and low Miller capacitance ratio (C_GD/C_GS ≈ 0.12), minimizing false turn-on risk even under high dV/dt conditions.

Can SIPC26N80C3 replace SPP20N60C3 in an existing 600 V PFC design?

No direct replacement: SPP20N60C3 is rated for 600 V, while SIPC26N80C3 is 800 V. Though electrically compatible in gate drive and R_DS(on), the higher voltage rating increases die size and gate charge (53 nC vs. 42 nC), potentially degrading efficiency at 400 V DC bus. Re-optimization of gate drive and layout is required.

Is the TO-220FP package of SIPC26N80C3 lead-free and RoHS compliant?

Yes. SIPC26N80C3 meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations and halogen-free molding compound. The TO-220FP package complies with JEDEC TO-220AB mechanical standards and supports reflow soldering per IPC/JEDEC J-STD-020D.2.
