Product details

800 V N-channel in a TO-252 — the switching converter workhorse

Packaged in a TO-252-3 (DPak) surface-mount case, it targets high-voltage offline switch-mode power supplies, flyback converters, and PFC stages where the 800 V rating gives headroom for universal-input AC-DC designs.

On-resistance and gate charge — the efficiency trade-off

The 250 pF input capacitance at 500 V drain-source confirms the low-Qg profile; the driver sees a light capacitive load, which simplifies gate-drive transformer design in isolated converters.

Frequently asked questions

Is IPD80R1K4P7ATMA1 RoHS compliant?

Yes, it is listed as ROHS3 Compliant.

What is the IPD80R1K4P7ATMA1's gate charge and why does it matter?

The maximum gate charge is 10 nC at 10 V. This low value means the MOSFET switches fast with minimal drive power — a good fit for high-frequency converters where gate-drive losses eat into efficiency.

Can IPD80R1K4P7ATMA1 replace IPD80R1K4P7?

The IPD80R1K4P7ATMA1 is the current suffix variant of the base IPD80R1K4P7. The suffix indicates packaging and tape/reel options. Verify the specific package code (PG-TO252-2) and electrical ratings match your BOM before substituting.
