Product details
Overview
STFI26NM60N from STMicroelectronics is an N-channel power MOSFET with 600 V, fully insulated TO-220FP package. It is chosen for voltage-driven power switching where RDS(on), gate charge, avalanche limits, and thermal impedance set the real design margin.
STFI26NM60N is most relevant to offline SMPS, PFC boost stages, industrial power supplies, lighting and inverter power stages, where the surrounding circuit depends on the same rating profile, footprint, thermal behavior, and sourcing continuity.
Technical Context
STFI26NM60N is a voltage-driven switching device where RDS(on), gate charge, threshold behavior, avalanche capability, and thermal impedance shape real performance.
The package and PCB copper often set the practical current more than the headline rating. Gate-driver voltage, switching speed, SOA, and body-diode behavior should be reviewed together.

Applications
| offline SMPS | PFC boost stages |
|---|---|
|
Use Scenario: offline SMPS where the design needs 600 V behavior from STFI26NM60N. Device Role: STFI26NM60N provides the N-channel power MOSFET function in the local circuit block. Use Value: The part keeps the fully insulated TO-220FP package footprint and rating profile aligned with the intended board function. |
Use Scenario: PFC boost stages requiring the device family behavior instead of a generic component choice. Device Role: STFI26NM60N handles the switching, protection, control, memory, or power-path task defined by its category. Use Value: Using the correct family reduces requalification risk around timing, voltage, current, thermal, and package constraints. |
| industrial power supplies | lighting and inverter power stages |
|
Use Scenario: industrial power supplies where operating stress, package size, and sourcing continuity all matter. Device Role: STFI26NM60N sits in the circuit as a BOM-controlled part rather than a cosmetic ordering code. Use Value: The device-specific rating and package information help engineers avoid unsuitable substitutions during procurement. |
Use Scenario: lighting and inverter power stages for legacy, current-production, or lifecycle-sensitive assemblies. Device Role: STFI26NM60N supports the same product-family function when matched to the existing schematic and layout. Use Value: A careful match protects system behavior while giving buyers a traceable sourcing path. |
Equivalent & Alternatives
When evaluating STFI26NM60N equivalent devices, compare voltage rating or operating class, current or output capability, package and footprint, pin mapping or polarity, thermal behavior, qualification suffix, lifecycle and sourcing status. A similar family name is not enough when the board depends on timing, leakage, firmware, optical output, or protection behavior.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STFI26NM60N | Base ordering family related to STFI26NM60N, usually differing by suffix, reel, lead finish, or package code. | May help sourcing discussions but does not remove the need for electrical and mechanical comparison. | Use only after matching ratings, pinout or polarity, package, qualification, and lifecycle status. |
Quality

FAQ
What is STFI26NM60N used for?
STFI26NM60N is used for offline SMPS, PFC boost stages, industrial power supplies. In those circuits, STFI26NM60N provides the N-channel power MOSFET function with 600 V, fully insulated TO-220FP package. The final selection should match the schematic role, operating stress, package footprint, and sourcing requirements.
What MOSFET parameters matter most for STFI26NM60N?
STFI26NM60N should be compared by voltage rating, RDS(on), gate charge, threshold range, package thermal resistance, avalanche behavior, SOA, and body-diode performance. These parameters decide whether STFI26NM60N can handle the real switching waveform and board temperature.
What gate-drive checks are needed for STFI26NM60N?
STFI26NM60N needs a gate-drive voltage, gate resistor, switching speed, and protection network that fit the circuit. A similar MOSFET can run hotter or switch poorly if STFI26NM60N is replaced without checking gate charge and drive strength.
Can STFI26NM60N be replaced by a similar part?
STFI26NM60N can be compared with similar family members only after electrical limits, package, orientation, qualification suffix, timing or leakage behavior, and approved-source rules are reviewed. A similar name alone is not enough because STFI26NM60N may carry package, program, bin, or lifecycle details.
Why source STFI26NM60N through Aetrix Electronics?
Sourcing STFI26NM60N through Aetrix Electronics supports traceable procurement, scheduled delivery planning, BOM continuity assistance, and lifecycle availability coordination. This is useful when STFI26NM60N is needed for production builds, repair lots, controlled alternates, or long-running equipment support.
