600 V, 13 A N-channel — FDmesh™ II in a TO-220
The STP18NM60ND: Through-hole TO-220-3 package.
290 mOhm at 10 V — the drive voltage constraint
Gate threshold max is 5 V at 250 µA.
ST is no longer manufacturing this exact order code. The replacement path is not officially documented in the available records, so a pin-compatible drop-in from ST's current FDmesh or MDmesh families needs a datasheet cross-check on gate charge and Rds(on) to confirm the switching performance matches. For a production run, qualifying a substitute is the safer move than chasing dwindling surplus lots.
Sourcing reality for an obsolete TO-220 MOSFET
Because this part is obsolete, the usual franchise channel is closed. Independent distributors and surplus brokers are the only source. Do not expect a steady pipeline; if you need a few hundred pieces for a repair or a short production run, the surplus market can usually cover it. For a new design, do not spec this part — pick a current-production 600 V N-channel in TO-220 from ST's active portfolio.
