Key Features
- 1000V drain-source breakdown voltage enables safe operation in high-voltage mains-connected circuits and industrial power topologies
- 110mJ avalanche energy rating with built-in body diode provides reliable protection against voltage transients in inductive flyback circuits
- DPAK-3 surface-mount package combines compact PCB footprint with adequate thermal dissipation for medium-power high-voltage designs
- Single-element configuration with METAL-OXIDE SEMICONDUCTOR technology ensures predictable, well-characterized switching behavior for precision power control
Applications
The STD3NK100Z is suited for offline high-voltage power supplies, flyback SMPS auxiliary stages, and gate drive circuits operating at voltages up to 1000V from rectified AC mains. Its 1000V breakdown voltage and 110mJ avalanche capability make it effective in industrial power metering, PLC power supply modules, and building automation controllers that must withstand transient overvoltages from inductive loads. The device also serves as a high-voltage switch in lighting ballast circuits, motor soft-starters, and precision high-voltage instrumentation power stages.

Frequently Asked Questions
What are the key voltage and current ratings of the STD3NK100Z?
The STD3NK100Z is rated for a 1000V minimum drain-source breakdown voltage, 2.5A maximum continuous drain current, and a 6-ohm maximum on-resistance. The 1000V rating is among the highest available for surface-mount N-channel MOSFETs, making it one of the few compact options for mains-voltage-connected switch-mode designs that require 1kV headroom.
What package does the STD3NK100Z use, and how does it compare to through-hole alternatives?
The STD3NK100Z is housed in a DPAK-3 (TO-252) surface-mount package with the drain connected to the exposed pad for PCB thermal dissipation. Compared to through-hole TO-92 or TO-220 packages used in similar 1000V applications, the DPAK-3 enables automated SMT assembly and a lower profile on the PCB while maintaining sufficient thermal performance for the device's 2.5A current rating.
What is the avalanche energy capability of the STD3NK100Z, and why does it matter?
The STD3NK100Z is rated for 110mJ of unclamped inductive switching (UIS) avalanche energy. This capability is important in flyback power supplies and inductive load switching circuits where voltage spikes can exceed the supply voltage and push the device into avalanche breakdown. The 110mJ rating allows the device to absorb these transients without damage, improving system reliability.
What applications are best suited for the STD3NK100Z?
Ideal applications include offline flyback SMPS auxiliary power stages, industrial power meter front ends, PLC power supply units, and high-voltage lighting ballast controllers operating from rectified 220V or 277V AC mains. The device also suits motor soft-start circuits, high-voltage instrumentation power rails, and protection switch circuits in industrial automation equipment where a 1000V breakdown voltage is required.
Is the STD3NK100Z RoHS compliant, and what is its availability status?
The STD3NK100Z is RoHS compliant and halogen-free per its JESD-609 e3 rating, suitable for products requiring environmental compliance certifications. The factory lead time is approximately 13 weeks for direct orders. Authorized STMicroelectronics distributors typically stock the device in DPAK-3 tape-and-reel format for immediate delivery. The YTEOL value of 6 indicates ongoing product support with several years of availability planned.
