Overview
Description
FQD2N90TM is a high‑voltage N‑channel MOSFET (enhancement mode) from Fairchild/Fairchild’s successor (onsemi). It targets switching power electronics, especially high‑voltage applications such as offline power supplies and HV motor drives. Key feature: VDS = 900 V, with rugged switching performance suitable for flyback/buck converters and other high‑voltage topologies. The TM suffix typically indicates a Tape & Reel packaging option. For exact numbers—continuous drain current, on‑resistance (Rds(on)), gate charge, switching speeds, and safe operating area—consult the latest datasheet. Gate drive requires an appropriate voltage (not a logic‑level input) and proper protection; adequate heatsinking may be needed due to power dissipation.
Features
FQD2N90TM is a high‑voltage N‑channel MOSFET. Key features:
- Type: N‑channel enhancement MOSFET
- Voltage rating: 900 V (Vds)
- Continuous drain current: typically around 2 A (depends on package and temp)
- On‑resistance: specified in datasheet (high, as expected for 900 V devices)
- Gate threshold: approximately 2–4 V; Vgs ≈ 10 V recommended for full conduction
- Protection/robustness: avalanche rugged, suitable for high‑voltage switching; intrinsic body diode
- Switching: designed for high‑voltage switching applications (offline SMPS, inverters)
- Packaging: TM suffix denotes tape‑and‑reel version; exact package variants (e.g., TO‑220AB, DPAK) available—verify in datasheet
Note: For exact values (Id, Rds(on), switching times, Qgs, etc.), consult the official datasheet for the precise package version you’re using.
