Product details
Overview
UPA1814GR-9JG-E1-A from Renesas Electronics is a P-channel enhancement-mode MOSFET designed for low-voltage DC power switching in portable electronics. It features RDS(on) = 16 mΩ max at VGS = –10 V / ID = –3.5 A, supports direct 4 V gate drive, and integrates a G–S ESD protection diode. It is used as a load switch in battery-powered devices such as PDAs and digital cameras.
For engineers reviewing the UPA1814GR-9JG-E1-A datasheet, UPA1814GR-9JG-E1-A pinout, UPA1814GR-9JG-E1-A application, or UPA1814GR-9JG-E1-A equivalent, key selection criteria include its –30 V VDSS, ±7.0 A ID(DC), 2.0 W power dissipation on ceramic substrate, and compatibility with 4.0–4.5 V logic-level gate drive in compact Power TSSOP8 packaging.
Technical Context
This device operates as a single P-channel silicon MOSFET with a built-in gate–source ESD protection diode. Its threshold voltage range (VGS(off) = –1.0 to –2.5 V) ensures reliable turn-on with low-voltage controllers, while its low input capacitance (Ciss = 2180 pF) and fast switching times (td(on) = 30 ns, tf = 86 ns) support efficient high-frequency PWM control.
The MOSFET's channel temperature rating of 150 °C and derated safe operating area (SOA) up to 100 ms pulses enable robust operation under transient load conditions. Its RDS(on) increases predictably with temperature-e.g., +25% at 125 °C vs. 25 °C under VGS = –4.0 V-supporting thermal-aware design in space-constrained applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | –30 V: Maximum drain–source blocking voltage; suitable for 24 V nominal systems with margin. |
| RDS(on) @ VGS = –10 V | 16 mΩ max: Enables <100 mW conduction loss at 3.5 A, reducing thermal load in portable designs. |
| ID(DC) | ±7.0 A: Continuous drain current rating when mounted on 5000 mm² ceramic substrate. |
| QG | 38 nC: Total gate charge determines driver strength requirement for 100 kHz+ switching. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET switching applications.
| 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) = 2.6 A. | Suitable only for sub-2 A loads; limited thermal mass for sustained conduction. | Select when board space is critical and current demand is ≤2 A; not recommended for 3.5 A continuous use. |
| AO3401 | RDS(on) = 44 mΩ @ –4.5 V; SO-8 package; higher QG = 12 nC; no integrated G–S diode. | Requires external ESD protection; slower switching due to higher gate charge. | Choose where cost is prioritized over thermal performance and ESD robustness; verify external protection layout. |
Compared with Si2301DDS-T1-GE3 and AO3401, the UPA1814GR-9JG-E1-A delivers superior conduction efficiency at 3.5 A, integrated ESD protection, and faster switching-making it optimal for thermally constrained, medium-power portable switching where reliability and gate-drive simplicity are essential.

FAQ
What is the maximum continuous drain current rating for UPA1814GR-9JG-E1-A?
The UPA1814GR-9JG-E1-A has a rated continuous drain current (ID(DC)) of ±7.0 A when mounted on a 5000 mm² ceramic substrate per the datasheet. This rating assumes proper thermal management; derating is required above 25 °C ambient, with full derating to zero at 100 °C ambient per the derating curve. Actual usable current depends on PCB copper area, airflow, and duty cycle.
Does UPA1814GR-9JG-E1-A require an external gate resistor for typical switching applications?
The UPA1814GR-9JG-E1-A does not mandate an external gate resistor for basic on/off control, but a small series resistor (e.g., 5–22 Ω) is recommended to damp ringing and limit peak gate current during fast transitions. The datasheet specifies switching times (e.g., tr = 140 ns) using RG = 10 Ω, confirming this value provides stable, reproducible performance without oscillation in standard layouts.
Can UPA1814GR-9JG-E1-A be used as a high-side switch with 3.3 V logic control?
Yes, UPA1814GR-9JG-E1-A is explicitly characterized for 4 V gate drive and exhibits RDS(on) = 24 mΩ max at VGS = –4.5 V and ID = –3.5 A. With a 3.3 V logic high referenced to source, VGS ≈ –3.3 V yields usable but higher RDS(on) (~27 mΩ max), making it functional for moderate-current (<2 A) high-side switching where efficiency is secondary to simplicity.
Is the body diode in UPA1814GR-9JG-E1-A suitable for reverse polarity protection?
No-the intrinsic body diode in UPA1814GR-9JG-E1-A conducts from source to drain (S→D), so it cannot block reverse input voltage. For reverse polarity protection, the device must be placed in the high-side position with source connected to input and drain to load; conduction then occurs only when input polarity is correct. The diode's VF(S-D) = 0.79 V at 7.0 A confirms forward conduction capability, but it is not a dedicated protection feature.
What is the quality grade of UPA1814GR-9JG-E1-A per Renesas documentation?
Per Renesas' quality grading policy stated in the datasheet, the UPA1814GR-9JG-E1-A is classified as "Standard" grade unless otherwise specified. This means it is qualified for applications including portable electronics, office equipment, communications devices, and industrial robots-but not for automotive safety-critical, medical life-support, or aerospace systems without explicit requalification and written consent from Renesas Electronics.
