150 V, 43 A, 7.5 mOhm — the TO-220 Full Pack power switch
The IPA075N15N3: The TO-220 Full Pack (PG-TO220-3-111) package has a fully isolated metal tab — no insulating pad or washer needed between the device and the heatsink. This simplifies assembly and improves thermal transfer reliability in through-hole designs.
Gate charge and switching speed
The 7280 pF input capacitance at 75 V Vds contributes to the switching energy; the driver must supply the charge during the Miller plateau. The recommended drive voltage range is 8 V to 10 V for achieving the rated on-resistance. The maximum gate-source voltage is ±20 V, providing margin against ringing on the gate node in hard-switching topologies.
Thermal limits and operating range
The 175°C Tj(max) suits applications with high ambient temperatures — motor drives in enclosures, automotive under-hood electronics, and industrial power supplies where the device sees sustained thermal stress. The threshold voltage is 4 V maximum at 270 µA drain current. This means the device turns on fully with standard 10 V or 12 V gate drive rails, but may not be fully enhanced with 5 V logic-level drive — a gate driver or bootstrap circuit is recommended.
The device is manufactured by Infineon Technologies and is RoHS-compliant per the standard lead-free assembly process. The bulk package (tube) is suitable for through-hole assembly lines and manual prototyping.
