Product details
Overview
The UPA2814T1S-E2-AT from Renesas Electronics is a P-channel MOSFET optimized for high-efficiency DC/DC converters and power management in portable electronics, featuring −30 V VDSS, −24 A ID(DC), and 7.8 mΩ RDS(on) at VGS = −10 V. Its HWSON-8 package with integrated heat spreader supports compact, thermally demanding designs.
For engineers reviewing the UPA2814T1S-E2-AT datasheet, UPA2814T1S-E2-AT pinout, UPA2814T1S-E2-AT application, or UPA2814T1S-E2-AT equivalent, key selection criteria include gate-drive compatibility down to −4.5 V, avalanche energy rating (48.4 mJ), channel-to-case thermal resistance (6.3 °C/W), and Pb-free/Halogen-free compliance for portable power stages.
Technical Context
This device operates as a synchronous rectifier or high-side switch in buck converters and battery protection circuits, leveraging its low RDS(on) and fast switching (td(off) = 130 ns, tf = 220 ns) under −10 V gate drive. Its body diode exhibits VF(S-D) = 0.9 V at 24 A, enabling efficient freewheeling without external Schottky diodes.
The HWSON-8 package places all four drain terminals (pins 5–8) on one side for low-inductance, high-current routing, while source terminals (pins 1–3) and gate (pin 4) are arranged for minimal loop area. Thermal design relies on direct case-to-PCB conduction, supported by Rth(ch-C) = 6.3 °C/W and Rth(ch-A) = 83.3 °C/W on a 25.4 mm × 25.4 mm glass epoxy board.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si2301DDS-T1-GE3 | RDS(on) = 115 mΩ @ −4.5 V; smaller SOT-23 package; lower ID(DC) = −2.7 A | Suitable only for sub-1 A loads; lacks avalanche rating and thermal performance for DC/DC primary switches | Select when board space is critical and current < 1.5 A; not suitable as drop-in replacement for UPA2814T1S-E2-AT in 24 A applications. |
| DMG2305UVT-7 | RDS(on) = 48 mΩ @ −4.5 V; TSOP-6 package; no specified EAS or IAS | Acceptable for low-power load switching but insufficient for repetitive avalanche stress in DC/DC converters | Prefer for cost-sensitive 1–2 A applications where thermal margin and transient robustness are secondary. |

FAQ
What is the maximum continuous drain current for the UPA2814T1S-E2-AT at 25°C ambient?
The UPA2814T1S-E2-AT supports −24 A continuous drain current (ID(DC)) at TC = 25°C, measured with the device mounted on a standard 25.4 mm × 25.4 mm glass epoxy board. This rating assumes proper PCB copper area for heat spreading via the exposed drain pad. At higher ambient temperatures, derating applies per the datasheet's forward bias SOA curve.
Does the UPA2814T1S-E2-AT support 5 V gate drive in practical applications?
Yes, the UPA2814T1S-E2-AT is fully characterized at VGS = −4.5 V, delivering RDS(on) ≤ 14.5 mΩ at −12 A. This makes it compatible with standard 5 V logic outputs and USB PD controller GPIOs without external level shifting-critical for compact portable designs where board space is constrained.
What is the thermal resistance from channel to case for the UPA2814T1S-E2-AT?
The UPA2814T1S-E2-AT has a channel-to-case thermal resistance (Rth(ch-C)) of 6.3 °C/W, measured from junction to the exposed drain pad. This value enables effective heat transfer to the PCB when the pad is soldered to a minimum 100 mm² copper pour, supporting >3 W continuous power dissipation in well-designed layouts.
Is the UPA2814T1S-E2-AT rated for avalanche energy, and what is its value?
Yes, the UPA2814T1S-E2-AT is explicitly rated for single-pulse avalanche operation with IAS = 22 A and EAS = 48.4 mJ under defined test conditions (VDD = −15 V, L = 100 μH, RG = 25 Ω). This rating validates its robustness during inductive turn-off transients common in DC/DC converter switching nodes.
What package type does the UPA2814T1S-E2-AT use, and how are its pins configured?
The UPA2814T1S-E2-AT uses the HWSON-8 package (Renesas code PWSN0008JB-A), a 3.0 mm × 3.0 mm surface-mount outline with an exposed drain pad. Pins 1–3 are source, pin 4 is gate, and pins 5–8 are drain-each drain pin electrically and thermally connected to the exposed pad for low-inductance, high-current routing and efficient heat dissipation.
