Device Overview
UF3C120150K3S is a Qorvo JFET in a TO-247-3L package. Selection of this exact part is driven primarily by Drain-Source Voltage (1200 V), RDS(on) (150 mOhm), Exact Package (TO-247-3L).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Drain-Source Voltage | 1200 V (onsemi SiC JFET usage table) | Defines the electrical voltage envelope that must cover the intended operating or stress level. |
| RDS(on) | 150 mOhm (25 C column in onsemi usage table) | Affects conduction loss and heat generation under the stated current, gate-drive and temperature conditions. |
| Exact Package | TO-247-3L | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
| Device Type | Normally-off SiC cascode FET | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
| Continuous Drain Current | 18.4 A (25 C column in onsemi usage table) | Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits. |
Power-Device Selection Notes
1200 V is the stated drain-source voltage value. Defines the electrical voltage envelope that must cover the intended operating or stress level. Technical condition: onsemi SiC JFET usage table. For device type, JFET is the approved value. Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared.
At 150 mOhm, the rds(on) affects conduction loss and heat generation under the stated current, gate-drive and temperature conditions. Technical condition: 25 C column in onsemi usage table.
For exact package, TO-247-3L is the approved value. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
At 18.4 A, the continuous drain current defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits. Technical condition: 25 C column in onsemi usage table.
