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.

Temperature range and environment

Junction temperature spans -55 °C to 175 °C. The gate threshold voltage is 2 V max at 77 µA drain current.

Lifecycle and sourcing

No end-of-life notice or last-time-buy schedule is in effect, so it can be specified into new designs without an obsolescence risk.

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.
