FDR8508P

FET, MOSFET Arrays Overview

The FDR8508P is a dual P-channel MOSFET array from onsemi's PowerTrench series, housed in a SuperSOT-8 surface-mount package. It features a drain-source voltage (Vdss) of -30 V and a continuous drain current (Id) of -3 A at 25°C. The device exhibits a maximum static drain-source on-resistance (Rds(on)) of 52 mΩ at Vgs = -10 V and Id = -3 A. Key electrical parameters include a gate threshold voltage (Vgs(th)) max of -3 V, total gate charge (Qg) max of 12 nC at Vgs = -5 V, and input capacitance (Ciss) max of 750 pF at Vds = -15 V. Maximum power dissipation is 800 mW, with an operating junction temperature range of -55°C to +150°C.
