Key Features
- Ultra-low drain-source on-resistance of 0.11 Ω minimizes conduction losses in high-current switching stages
- 600 V breakdown voltage with 345 mJ avalanche energy rating ensures robust operation in demanding inductive load environments
- Isolated TO-220FP package simplifies thermal management by eliminating the need for additional insulating hardware
Applications
The STF34NM60ND is suited for switch-mode power supplies (SMPS), industrial motor drives, and PFC boost converters operating from rectified mains. Its 600 V rating and built-in body diode make it a reliable choice for half-bridge and full-bridge topologies. Power-factor-correction stages in server and telecom power units also benefit from its ultra-low resistance and robust avalanche capability.

Frequently Asked Questions
What is the maximum continuous drain current the STF34NM60ND can handle at 25°C?
The STF34NM60ND is rated for a maximum continuous drain current (ID) of 29 A at 25°C. This makes it suitable for switch-mode power supplies and motor drives requiring moderate-to-high current handling in a compact TO-220FP package.
How does the ultra-low 0.11 Ω on-resistance benefit a PFC boost converter design?
With a maximum drain-source on-resistance of 0.11 Ω, the STF34NM60ND keeps conduction losses to a minimum during the switch-on interval. In a PFC boost converter operating at 10 A, this translates to roughly 11 W of conduction loss reduction compared to devices with higher RDS(on), improving overall efficiency above 95% in many designs.
When would an isolated TO-220FP package be preferred over a standard TO-220 for the STF34NM60ND?
The isolated TO-220FP package is preferred whenever the heatsink must be electrically shared by multiple components or grounded to the chassis. Because the tab is isolated from the drain, no additional insulating washer or mica pad is needed, saving assembly time and reducing thermal resistance in industrial power supplies operating at 400 V AC mains input.
What avalanche energy capability does the STF34NM60ND offer, and why does it matter for inductive loads?
The STF34NM60ND is rated for an avalanche energy (Eas) of 345 mJ. In circuits driving inductive loads such as motors or transformers, unclamped energy can spike the drain voltage above 600 V; the 345 mJ rating ensures the device survives repetitive avalanche events without degradation, improving system reliability.
