The 620 V Vdss gives a comfortable margin for universal-input (85–265 VAC) offline converters after derating for leakage inductance spikes; a 600 V device would be marginal in the same spot. The 4.5 A continuous rating at case temperature 25°C is the headline number, but at a realistic 85°C ambient the current must be derated per the thermal curve — the 70 W package limit (Tc) is the real constraint. Gate charge of 23 nC at 10 V is modest, keeping switching losses manageable for a 620 V device in the 50–100 kHz range. Input capacitance of 560 pF at 50 V drain-source is low enough that the gate driver does not need a high peak current — a standard totem-pole driver suffices. ## Obsolete — sourcing and replacement strategy For new designs, a parametric search for a 620 V N-channel MOSFET in DPAK with similar Rds(on) and gate charge is the practical path.","metaTitle":"STMicroelectronics STDLED625H N-Channel MOSFET, 620 V, 4.5 A","metaDescription":"STMicroelectronics STDLED625H N-Channel MOSFET, 620 Vds, 4.5 A Id, 2 Ohm Rds(on) at 10 V.
