SI1029X-T1-E3

Overview

The Vishay Siliconix Si1029X-T1-E3 is a complementary N- and P-channel MOSFET in an SC-89 (SOT-563F) package. It features a 60 V drain-source voltage rating with typical on-resistances of 1.40 Ω for the N-channel and 4 Ω for the P-channel at VGS = 10 V. The device offers a low threshold voltage of ± 2 V (typical) and fast switching speeds of 15 ns (typical). Gate-source ESD protection is rated at 2000 V, and it operates within a junction temperature range of -55 °C to +150 °C.
