SQ2325ES-T1_GE3 Overview
A P-Channel MOSFET is a type of field-effect transistor where the conducting channel is formed by holes rather than electrons; it is activated by pulling the gate voltage below the source potential. P-Channel devices belong to the broader MOSFET family, which sits under discrete semiconductors in power-management and load-switching hierarchies. They are commonly used for high-side switching because, when the gate is grounded, the device turns on and pulls the load to the negative rail, simplifying drive circuitry in systems with a positive supply.
Key features include 150 V VDS breakdown voltage, 840 mA continuous drain current at 25 °C case temperature, low on-resistance typical of Vishay TrenchFET silicon, and halogen-free construction per IEC 61249-2-21. The SOT-23-3 footprint keeps board area to roughly 4 mm² while still providing sufficient thermal dissipation for low-to-moderate power switching. Gate threshold voltage is specified to drive directly from logic-level signals or simple microcontroller GPIO outputs, depending on variant.
Architecturally, the SQ2325ES uses Vishay's TrenchFET® vertical trench-gate process, which reduces specific on-resistance (RDS(on) × area) by concentrating the channel along a vertical trench sidewall rather than on the wafer surface. This yields lower conduction losses per unit silicon area compared with older planar P-Channel processes. The AEC-Q101 qualification and 100 % UIS testing make the part especially suited to automotive load-dump and inductive-load environments.
Typical applications include automotive load switching, high-side power management in 12 V / 24 V systems, reverse-battery protection, level shifting, and general low-power switching where a small-footprint P-Channel device is required. It can also serve as a power-ORing element or as a bootstrap switch in half-bridge driver circuits.
When designing with this part, ensure that the gate-to-source voltage stays within the absolute maximum rating (typically ±20 V) and that switching losses are kept within the package's thermal limits. The SOT-23-3 package relies on the drain tab (pin 3) for primary heat dissipation, so adequate copper area on the drain pad is essential for thermal performance.

Typical Applications
SQ2325ES-T1_GE3 is suitable for 6 applications: Automotive 12V/24V Load Switching, Reverse-Battery Protection, Level Shifter / Voltage Translator Switch, Power-ORing and Load Sharing, Bootstrap Switch for Half-Bridge Drivers, Battery Monitoring and Protection in Portable Devices.
Automotive 12V/24V Load Switching
The SQ2321ES-T1_GE3's 150 V VDS rating and AEC-Q101 qualification make it a strong candidate for high-side switching on 12 V and 24 V automotive rails. With 840 mA continuous drain current and 3 W power dissipation at TC = 25 °C, it can drive solenoids, lamps, and small motors while tolerating inductive flyback transients common in automotive wiring harnesses. Its 100 % UIS testing confirms ruggedness under unclamped inductive load events. The SOT-23-3 footprint keeps PCB area under 4 mm², leaving room for dense body-electronics modules.
Recommended
Reverse-Battery Protection
The P-Channel SQ2321ES-T1_GE3 enables a classic reverse-battery protection topology: source to battery +, drain to downstream load, gate tied to ground through a Zener or resistor network. Under normal polarity the device conducts with low RDS(on); during reverse polarity the body diode blocks and the gate drive keeps the device off. The 150 V VDS rating provides ample margin against automotive load-dump transients up to ~100 V, while AEC-Q101 qualification validates the part for under-hood and body-control environments.
Recommended
Level Shifter / Voltage Translator Switch
The SQ2321ES-T1_GE3's P-Channel configuration simplifies level shifting between two supply domains: a logic-level signal on the gate enables conduction between a higher-voltage rail (at the source) and a lower-voltage load (at the drain). For 3.3 V microcontrollers driving 12 V or 24 V loads, the part's gate threshold and 150 V breakdown give plenty of headroom. This topology avoids the charge-pump circuitry often required when using N-Channel high-side switches, reducing BOM count and PCB area.
Recommended
Power-ORing and Load Sharing
Two P-Channel MOSFETs wired source-to-source with gates tied together create a low-loss power-ORing circuit for redundant supplies. The SQ2321ES-T1_GE3's 150 V VDS rating supports bus voltages up to 100 V in ORing configurations, while its AEC-Q101 qualification allows deployment in automotive and industrial redundant-power architectures. Compared with Schottky-diode ORing, MOSFET ORing reduces conduction losses by an order of magnitude at load currents above 500 mA.
Recommended
Bootstrap Switch for Half-Bridge Drivers
In half-bridge driver circuits for MOSFETs and IGBTs, a P-Channel bootstrap switch refreshes the bootstrap capacitor when the low-side switch is on. The SQ2321ES-T1_GE3, with its 150 V rating and small SOT-23-3 footprint, can serve as this refresh switch in motor-drive and DC-DC converter applications. Its AEC-Q101 qualification extends applicability into automotive 12 V motor drives such as pumps, fans, and small actuators.
Recommended
Battery Monitoring and Protection in Portable Devices
Although the SQ2321ES-T1_GE3 is automotive-qualified, its SOT-23-3 footprint and 150 V VDS also suit portable battery packs as a high-side disconnect switch. The P-Channel configuration keeps gate drive simple: pulling the gate to ground turns the device on. With 840 mA continuous current and 3 W dissipation, it can handle single-cell Li-ion load switching as well as protection against external voltage transients in industrial handheld instruments.

Design Notes
Estimated: at TA = 25 °C on a 1 sq-in 2-oz FR-4 board, the SOT-23-3 package typically exhibits θJA ≈ 150 °C/W. With PD_max = 3 W at TC = 25 °C, the achievable continuous drain current on real PCB area is roughly 300-400 mA, not the 840 mA datasheet TC value. Increase drain-pad copper area or use thermal vias to a backside heatsink plane for high-duty-cycle loads.
Pin 3 (drain) is the primary thermal path. Per the Vishay LITTLE FOOT datasheet convention, expand the drain copper pad with thermal vias to an internal or backside plane. Place the gate-drive resistor as close to pin 1 as possible to minimize parasitic inductance that could cause ringing on fast switching edges, especially when driving the gate from a microcontroller GPIO through long traces.
Do not exceed VGS_max = ±20 V on the gate. For P-Channel high-side switching with source tied to battery+, a gate-source Zener clamp (typically 10-15 V) prevents gate overvoltage during load-dump events. Also confirm that your drive logic can pull the gate to within VGS(th) below source to fully enhance the device; many 3.3 V microcontrollers struggle with 12 V source rails without a level shifter.
For switching speeds above 1 kHz, add a small gate-source resistor (10-100 kΩ) to prevent accidental turn-on from dv/dt-induced Miller coupling, and consider a gate-drive RC snubber (10 Ω + 1 nF) to slow the switching edge. P-Channel MOSFETs in high-side switching configurations can otherwise inject common-mode noise into sensitive analog circuits sharing the same ground reference.
When using the SQ2321ES-T1_GE3 in pulse-width-modulated (PWM) applications such as LED dimming or motor control, the source pin swings between battery voltage and load voltage. Place a 100 nF ceramic bypass capacitor directly across source-drain to absorb switching transients, and keep the gate-drive loop area minimal to avoid parasitic inductance causing gate-oxide stress.
Compliance Information
RoHS compliant to 2011/65/EU per Vishay datasheet front matter. Halogen-free per IEC 61249-2-21. AEC-Q101 qualified (note: AEC-Q100 field is set to qualified because the underlying automotive standard for discrete MOSFETs is AEC-Q101, which is the family qualification applicable to this part).
