Product details

Through-hole CoolMOS for 30 V load switching

The IPS105N03LG: It is designed for moderate-current 30 V rail switching where low on-resistance and fast switching are needed. Gate charge is 14 nC at 10 V.

175 °C junction — thermal headroom for tight enclosures

This gives extra margin in high-ambient environments such as under-hood automotive or sealed power supplies where the case temperature can climb. Maximum power dissipation is 38 W at case temperature Tc. The TO-251 package's exposed tab must be soldered to a sufficient copper area on the PCB to keep the junction below the 175 °C limit under sustained load.

Gate drive and switching profile

The device is specified for gate drive voltages of 4.5 V and 10 V, with the 10.5 mOhm Rds(on) achieved at 10 V. At 4.5 V the on-resistance will be higher. Maximum gate-source voltage is ±20 V. Input capacitance Ciss is 1500 pF typical at 15 V drain-source. Combined with the 14 nC gate charge, the gate driver sees a moderate capacitive load.

Active production, ROHS3 compliant

It is ROHS3 compliant.

Frequently asked questions

Is the IPS105N03LG a direct replacement for the IPP105N03LG?

The IPP105N03LG is the DPAK (TO-252) surface-mount variant of the same die. The IPS105N03LG is the through-hole TO-251 version. They are electrically identical but not footprint-compatible — the IPS105N03LG has three stub leads for through-hole mounting, while the IPP105N03LG has a surface-mount tab and gull-wing leads. No direct drop-in replacement without board layout change.

What is the maximum operating temperature for the IPS105N03LG?

This exceeds the typical industrial 150 °C limit, giving thermal headroom for high-ambient applications.
