Product details

Package and mounting — the D²Pak tab is the thermal path

It comes in a TO-263-3 (D²Pak) surface-mount package, supplier code PG-TO-263-3-2. The large drain tab on the bottom needs a good thermal pad on the PCB — a few vias to an inner-layer copper pour keep the junction below 175 °C at full load. The part is rated for 47 W power dissipation at the case, so the board-level heatsinking is what determines the real current you can pull continuously.

The gate threshold voltage is 2 V max at 77 µA drain current.

Frequently asked questions

What are the equivalent or alternative parts for IPB093N04LG?

The IPB093N04LG is an active, current-production part, so no direct replacement is needed. For a pin-compatible alternative within the same OptiMOS™ 3 family, look at other 40 V N-channel devices in the TO-263-3 package — the Rds(on) and gate charge will differ, so check the specific ratings against your design.
