Product details

Its maximum on-resistance sits at 1.3 Ohm when driven with a 10 V gate signal, which is the recommended drive voltage for achieving the lowest Rds(on).

Obsolete — sourcing reality and the replacement question

The gate charge of 34 nC at 10 V and the input capacitance of 895 pF at 100 V are moderate figures, so a functionally equivalent replacement from another manufacturer (same 650 V, 6 A class, N-channel, DPAK footprint) should be cross-referenced by the design team before committing a new build.

Package and reflow — DPAK (TO-252) on the line

The STDLED656 comes in a DPAK (TO-252-3, DPak with 2 leads plus tab) surface-mount package, also referred to as the SC-63 outline. For the reflow profile, this is a standard leaded surface-mount package — no exotic profile required, but the tab's solder coverage matters for thermal performance.

Frequently asked questions

What is a good replacement for STDLED656?

The lifecycle record does not list an official successor from ST. A functionally equivalent replacement should match the 650 V drain-to-source voltage, 6 A continuous drain current, N-channel polarity, and DPAK (TO-252) footprint. Consult the design team to validate any candidate against the circuit's switching and thermal requirements.
