Product details

950 V N-channel in a TO-220 — the high-voltage workhorse

The TO-220-3 through-hole package suits it for board-level mounting on aluminium-backed PCBs or heatsinks in industrial and telecom power supplies.

With a maximum Rds(on) of 1.25 Ohm at 3 A, 10 V, the STP6N95K5 is not the lowest on-resistance in the 950 V class, but the 13 nC typical total gate charge at 10 V is notably low. This combination favours designs where switching losses dominate — flyback converters running at 65-100 kHz, for example — because the driver can charge and discharge the gate quickly without a large current pulse. The input capacitance is 450 pF at 100 V drain bias, which keeps the Miller plateau short and reduces cross-conduction during hard-switching transitions.

The ±30 V maximum gate-source voltage gives some headroom for gate-drive overshoot in noisy power stages.

For new designs, the part is available through franchised and independent distribution; the BOM position is stable for the foreseeable future.

Frequently asked questions

What is the equivalent of STP6N95K5?

The closest peer in the same SuperMESH5™ family is the STW6N95K5, which shares the same 950 V Vdss, 9 A Id, 1.25 Ohm Rds(on), and 13 nC Qg ratings, but is supplied in a TO-247 package for higher power dissipation. The STP7N90K5 (900 V, 7 A, 810 mOhm) is a higher-current alternative in the same TO-220 footprint but with a different voltage class.
