SI4948BEY-T1-GE3

Overview

The Vishay Siliconix SI4948BEY-T1-GE3 is a dual P-channel enhancement mode MOSFET utilizing TrenchFET technology. It features a -60 V drain-source voltage rating and operates within a junction temperature range of -55 °C to +175 °C. The device provides two independent channels in an SO-8 surface-mount package. At VGS = -10 V, the maximum on-state resistance is 0.120 Ω with a continuous drain current of -3.1 A. At VGS = -4.5 V, the resistance increases to 0.150 Ω with a current of -2.8 A. Key dynamic parameters include a total gate charge of 22 nC and a forward transconductance of 8.5 S.

Procurement Notes

Verify component authenticity by checking the manufacturer's marking code against official documentation. Confirm the ordering suffix matches the required halogen-free specification (GE3). Ensure the package type corresponds to the narrow SOIC-8 outline defined in document 71192. Validate that the supplier provides traceability data consistent with Vishay manufacturing records.

Selection Notes

Select this component when a dual P-channel solution is required with a -60 V breakdown voltage. The -175 °C maximum junction temperature supports high-temperature environments. Verify that the gate drive voltage meets the threshold requirements for the desired on-resistance level. Consider the thermal resistance ratings for heat dissipation calculations in the target application layout.
