Product details
Overview
UPA1804GR-9JG-E1-A from Renesas Electronics is an N-channel MOSFET designed for low-voltage power switching in portable electronics. It features RDS(on) ≤ 23 mΩ at VGS = 10 V / ID = 4.0 A, supports direct 4.5 V gate drive, and integrates a G-S ESD protection diode. It is used as a main power switch in battery-powered DC-DC converter outputs and load management circuits.
For engineers reviewing the UPA1804GR-9JG-E1-A datasheet, UPA1804GR-9JG-E1-A pinout, UPA1804GR-9JG-E1-A application, or UPA1804GR-9JG-E1-A equivalent, key selection criteria include its 30 V VDSS, ±8.0 A DC drain current rating, 2.0 W power dissipation on ceramic substrate, and Power TSSOP8 package with drain-source thermal layout optimization.
Technical Context
The UPA1804GR-9JG-E1-A employs a trench-gate vertical DMOS structure optimized for fast switching and low conduction loss at logic-level gate drive. Its gate threshold voltage (VGS(off)) ranges from 1.0 V to 2.5 V, enabling reliable turn-on with 4.5 V supply while maintaining low leakage (IDSS ≤ 10 µA at VDS = 30 V).
Switching performance is characterized by td(on) = 24 ns, tr = 83 ns, td(off) = 46 ns, and tf = 29 ns under standard test conditions (VDD = 15 V, RG = 10 Ω), supported by QG = 13.5 nC and QGD = 3.7 nC - indicating moderate gate drive strength requirements for high-frequency operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - maximum blocking voltage for 5 V–12 V system rail switching |
| RDS(on)1 | 23 mΩ max @ VGS = 10 V, ID = 4.0 A - enables <100 mW conduction loss at 4 A load |
| RDS(on)2 | 32 mΩ max @ VGS = 4.5 V, ID = 4.0 A - ensures full enhancement with single Li-ion battery input |
| ID(DC) | ±8.0 A - continuous current capability with derating above 25°C ambient |
| QG | 13.5 nC - determines gate driver current requirement for <100 ns switching transitions |
| Tch max | 150°C - defines maximum junction temperature for thermal design margin |
| Ciss | 761 pF - impacts gate drive loop stability and Miller effect in high-side configurations |
Pinout & Package
UPA1804GR-9JG-E1-A is housed in a Power TSSOP8 package (6.4 mm × 4.4 mm × 1.0 mm), featuring exposed drain pads on pins 1, 5, and 8 for enhanced thermal conduction to PCB copper. The package uses gull-wing leads with 0.65 mm pitch and is rated for mounting on ceramic substrates (5000 mm² × 1.1 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8 | Drain | High-current output node; electrically and thermally connected to exposed pad - must be routed to large copper pour |
| 2, 3, 6, 7 | Source | Power return path; tied to ground plane; forms body diode cathode for reverse recovery handling |
| 4 | Gate | Control input; requires external series resistor (e.g., 10 Ω) to damp ringing per test circuit |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive compatibility | Guaranteed turn-on at VGS = 4.5 V - eliminates need for gate boosters in single-cell battery systems |
| Integrated G-S ESD protection diode | Provides Class 2 HBM ESD robustness without external components - reduces BOM count in space-constrained layouts |
| Low gate charge (QG = 13.5 nC) | Enables efficient 500 kHz–1 MHz switching with standard microcontroller GPIO or low-power drivers |
| Fast switching (tf = 29 ns) | Minimizes transition losses in high-frequency DC-DC converters - critical for >90% efficiency at light loads |
| Thermally optimized Power TSSOP8 | Exposed drain pads allow 62.5°C/W transient thermal resistance - supports 2.0 W dissipation with proper PCB layout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ROHM RQ3E080BN | RDS(on) = 8.0 mΩ @ VGS = 4.5 V; smaller TSMT8 package (3.0 × 3.0 mm) | Higher current density but lower thermal mass - requires tighter layout control for 8 A DC | Preferred when board space is constrained and gate drive ≥4.5 V is guaranteed |
| Vishay SI2308DS | RDS(on) = 32 mΩ @ VGS = 4.5 V; SOT-23 package with 3.2 A ID(DC) rating | Lower power handling and no exposed drain pad - limited to <1.5 W dissipation | Suitable for sub-3 A loads where cost and footprint outweigh thermal performance needs |
Compared with RQ3E080BN and SI2308DS, the UPA1804GR-9JG-E1-A offers balanced trade-offs: higher RDS(on) than RQ3E080BN but superior thermal performance via Power TSSOP8, and significantly higher current/power capability than SI2308DS - making it optimal for 4–8 A portable power switches requiring robust thermal management.

FAQ
What is the maximum continuous drain current rating for UPA1804GR-9JG-E1-A?
The UPA1804GR-9JG-E1-A has a rated continuous drain current (ID(DC)) of ±8.0 A at TA = 25°C when mounted on a 5000 mm² ceramic substrate. Derating applies above 25°C ambient - e.g., ~5.5 A at 70°C ambient per the derating curve in the datasheet. This rating assumes proper PCB copper area and thermal vias under the exposed drain pads.
Does UPA1804GR-9JG-E1-A require an external gate resistor?
Yes, the UPA1804GR-9JG-E1-A benefits from an external gate series resistor (typically 5–10 Ω) to control dV/dt and suppress ringing, especially in high-speed switching applications. The datasheet's Test Circuit 1 specifies RG = 10 Ω for switching time measurements, confirming this practice improves reliability and EMI performance.
Is UPA1804GR-9JG-E1-A suitable for automotive applications?
No - the UPA1804GR-9JG-E1-A is classified as a "Standard" quality grade device per Renesas documentation, intended for computers, office equipment, and portable electronics. It is not qualified to AEC-Q101 or rated for automotive temperature ranges (−40°C to +125°C ambient), and lacks automotive-specific reliability testing or PPAP support.
What is the purpose of the built-in gate-to-source protection diode in UPA1804GR-9JG-E1-A?
The built-in gate-to-source diode in the UPA1804GR-9JG-E1-A provides electrostatic discharge (ESD) protection per human-body model (HBM), helping prevent gate oxide damage during handling and assembly. However, Renesas explicitly states that external protection remains necessary if voltages exceeding ±20 V are expected - the internal diode alone does not replace full-system ESD safeguards.
Can UPA1804GR-9JG-E1-A be used in synchronous rectification topologies?
Yes - the UPA1804GR-9JG-E1-A supports synchronous rectification due to its low RDS(on) (23 mΩ max), fast switching (tf = 29 ns), and integrated body diode with trr = 27 ns and Qrr = 16 nC. Its gate threshold and capacitance profile enable clean commutation in secondary-side FET roles of isolated DC-DC converters operating up to 1 MHz.
