Description

Marked "20N60FJD2" on the package with the SL logo and "D-Well™" branding, this matches Hangzhou Silan Microelectronics' SVS20N60FJD2, part of their SVS20N60FJ(K)(T)(PN)(S)(P7)D2 product family. It's an N-channel enhancement mode high-voltage power MOSFET built on Silan's super junction MOS technology, which achieves low conduction loss and switching losses. The specific "FJD2" suffix corresponds to the isolated TO-220FJ-3L package variant, with the marking code "20N60FJD2" and halogen-free construction confirmed in Silan's own ordering information table.

The "D-Well" branding on the package likely refers to a private-label or distributor rebrand of the underlying Silan die — the electrical characteristics and marking code match Silan's part exactly, so this should be treated functionally as the SVS20N60FJD2.
