Infineon BUZ111SL-E3045A N-channel power MOSFET, 50 V drain-to-source, 80 A continuous drain at 25 °C, 300 W max dissipation, TO-263-3 (D²Pak) surface-mount package, 175 °C operating junction temperature.
| Parameter | Value |
|---|---|
| FET type | N-Channel |
| Mounting type | Surface Mount |
| Drain to source voltage | 50 V |
| Current - continuous drain (Id) @ 25°C | 80A |
| Power dissipation | 300W |
| Operating temperature | 175°C |
| Package | Bulk |
| Technology | MOSFET (Metal Oxide) |
| Case | TO-263-3, D²Pak (2 Leads + Tab), TO-263AB |
Surface-mount TO-263-3 (D²Pak) with two leads plus the tab. The tab is the drain connection — it needs a good solder joint to the PCB copper pour for both electrical and thermal paths. The supplier device package is listed as TO-263. No heatsink clip or through-hole hardware; the board copper is the heatsink.
No last-time-buy or end-of-life notice is in effect.
It is an N-channel MOSFET using Metal Oxide semiconductor technology.
