High Isolation Gate Drive Transformers
The PH9400.XXXNL and PH9400.XXXANL series are Surface Mount Technology (SMT) high isolation gate drive transformers designed for demanding applications. These transformers offer robust isolation capabilities, with up to 5000Vrms gate-to-drive isolation and rated voltages up to 1000Vpk. They are suitable for driving power semiconductor devices and can handle up to 8W of driver power. The "ANL" versions feature reinforced insulation compliant with IEC 61558, IEC 61010, and IEC 60601, while the "NL" versions comply with basic insulation requirements. The 12mm sidecar package provides ample creepage and clearance distances for safety compliance.

Notes:
- ET (Max) is calculated to limit core loss and temperature rise at 100KHz based on a bipolar flux swing of 2100Ga Peak. This value needs to be derated for higher frequencies.
- Temperature rise calculation is based on total core loss and copper loss.
- Creepage & clearance distance satisfies IEC 61558 requirements for working voltage up to 600Vrms/reinforced and 1000Vrms/basic based on material group III for OVC II, pollution degree 2 and altitude up to 5000m.
- Rated voltage is based on a positive partial discharge test (< 10pC) in accordance with IEC 60664.
