Product details

600 V CoolMOS™ N-channel — what it brings to the switching stage

It is rated for 3.2 A continuous drain current at 25 °C case temperature and carries a 1.4 Ohm maximum on-resistance when driven with a 10 V gate signal. The 16 nC typical gate charge keeps switching losses manageable in hard-switched topologies like PFC boost stages, flyback converters, and auxiliary power supplies. Junction temperature spans -55 to 150 °C, so it handles the thermal cycling of outdoor telecom or industrial power supplies without derating at the cold end.

Package and mounting — TO-252-3 (DPak) land pattern

The SPD03N60S5 uses the standard TO-252-3 (DPak) footprint with a single drain tab. The supplier device code is PG-TO252-3-313.

Infineon lists the SPD03N60S5 as Active with no end-of-life notification. ROHS3 compliance is confirmed, so it passes EU material restrictions for new designs. The CoolMOS™ S5 series is a mature, still-shipping portfolio; no second-source or direct replacement is needed for supply continuity. For BOM-freeze planning, this part carries no imminent PCN risk.

Frequently asked questions

What is the Rds(on) of SPD03N60S5?

Maximum on-resistance is 1.4 Ohm at 2 A drain current with a 10 V gate drive.

Is SPD03N60S5 compatible with IRF830?

Both are 500 V / 600 V class N-channel MOSFETs, but the SPD03N60S5 is a surface-mount TO-252 part while the IRF830 is a through-hole TO-220. Footprint and thermal management differ. The SPD03N60S5 has lower gate charge (16 nC vs roughly 30 nC for IRF830) and a higher voltage rating (600 V vs 500 V). They are not pin-compatible; a board redesign is needed to swap.

What is the closest pin-compatible alternative to SPD03N60S5?

Within the CoolMOS™ S5 family, the SPD03N60S5 has no direct pin-compatible sibling with identical ratings. For a drop-in replacement in the same TO-252 footprint, consider the SPD04N60S5 (4 A, lower Rds(on)) if the current margin allows. Verify gate charge and switching behaviour against the circuit.
