Product details
Overview
SI1023CX-T1-GE3 from Vishay Siliconix is a dual P-channel enhancement-mode TrenchFET® MOSFET rated for -20 V drain-source voltage, with RDS(on) = 0.756 Ω at VGS = -4.5 V and ID = -0.35 A, housed in an SC-89 (SOT-563F) 6-lead surface-mount package. It serves as a compact load switch in portable battery-powered systems requiring low gate charge (1 nC typical) and fast switching.
For engineers reviewing the SI1023CX-T1-GE3 datasheet, SI1023CX-T1-GE3 pinout, SI1023CX-T1-GE3 application, or SI1023CX-T1-GE3 equivalent, key selection criteria include its dual-channel P-channel topology, -1.5 V minimum gate threshold, 1000 V HBM ESD rating, and suitability for space-constrained DC-DC load switching and display backlight control in mobile platforms.
Technical Context
This device integrates two independent P-channel MOSFETs in a single SC-89 package, sharing no internal connection between channels. Each channel features trench-gate silicon technology optimized for low RDS(on) at low gate drive voltages down to -1.5 V, enabling direct interface with 1.8 V and 2.5 V logic outputs without level shifting.
Thermal performance is defined by RthJA = 675 °C/W (steady-state, 1" × 1" FR4), supporting continuous ID = -0.35 A per channel at ambient temperatures up to 70 °C. Dynamic parameters include Ciss = 45 pF, Qg = 1.65–2.50 nC, and tf = 5–16 ns, confirming suitability for high-frequency switching below 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -20 V - Maximum blocking voltage for battery-side high-side switching in 3.3 V/5 V systems |
| RDS(on) @ VGS = -4.5 V | 0.756 Ω - Enables <100 mW conduction loss at 0.35 A per channel |
| ID Continuous (TA = 25 °C) | -0.45 A - Dual-channel current capability supports independent low-power load control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel load switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si1022CX-T1-GE3 | Single-channel variant; identical RDS(on), Qg, and package but only one MOSFET | Requires two units for dual-load control; increases BOM count and layout area | Select when only one switched rail is needed or when channel independence is not required |
| DMC2038LVT-7 | Higher RDS(on) (1.2 Ω @ -4.5 V), larger SC-70-6 package, lower ESD rating (500 V HBM) | Less suitable for 1.8 V logic drive and high-density layouts; higher conduction loss at 0.3 A | Consider only if legacy design reuse or distributor stock availability dictates substitution |
Compared with SI1023CX-T1-GE3, Si1022CX-T1-GE3 doubles footprint and cost for dual functionality, while DMC2038LVT-7 sacrifices 58 % higher on-resistance and 50 % lower ESD immunity-making SI1023CX-T1-GE3 the optimal choice for new designs prioritizing density, efficiency, and robustness in portable power switching.

FAQ
What is the maximum continuous drain current per channel for SI1023CX-T1-GE3 at 70 °C ambient?
The SI1023CX-T1-GE3 supports -0.36 A continuous drain current per channel at TA = 70 °C, as specified in the Absolute Maximum Ratings table. This value assumes surface mounting on a 1" × 1" FR4 board with standard copper pour and accounts for thermal derating from the 25 °C rating of -0.45 A. Exceeding this current requires thermal analysis of the specific PCB layout.
Does SI1023CX-T1-GE3 integrate body diodes, and what are their forward voltage characteristics?
Yes, SI1023CX-T1-GE3 includes integrated source-drain body diodes for each channel. At IS = -0.3 A and TJ = 25 °C, the body diode forward voltage (VSD) is -0.8 to -1.2 V. The reverse recovery time (trr) is 16–24 ns under IF = -0.3 A and dI/dt = 100 A/µs conditions, confirming suitability for non-synchronous buck or flyback topologies with moderate switching frequency.
Can SI1023CX-T1-GE3 be driven directly by a 1.8 V microcontroller GPIO without level shifting?
Yes, SI1023CX-T1-GE3 can be driven directly by a 1.8 V microcontroller GPIO. Its gate threshold voltage (VGS(th)) ranges from -0.4 V to -1.0 V, ensuring reliable turn-on when the gate is pulled to 0 V (i.e., VGS = -1.8 V). No external level shifter is required, simplifying interface design in low-voltage portable systems.
What is the thermal resistance junction-to-ambient (RthJA) for SI1023CX-T1-GE3 under steady-state conditions?
The steady-state junction-to-ambient thermal resistance (RthJA) for SI1023CX-T1-GE3 is 675 °C/W, measured on a 1" × 1" FR4 board with standard 1 oz copper. This value reflects worst-case convection-only cooling and must be used for conservative thermal design. For improved performance, PCB copper area and thermal vias should be added beneath the exposed pad (if present) or package bottom.
Is SI1023CX-T1-GE3 suitable for use in automotive infotainment displays?
SI1023CX-T1-GE3 is not AEC-Q200 qualified and is specified for commercial temperature range (-55 to +150 °C), not automotive grade. While its electrical specs meet many infotainment subsystem requirements, Vishay does not certify it for automotive use. For such applications, engineers should select AEC-Q101-qualified alternatives like the SQJQ412EP or consult Vishay's automotive-grade portfolio before final design-in.
