Product details
Overview
UPA1809GR-9JG-E1-A from Renesas Electronics is a dual N-channel MOSFET in Power TSSOP-8 package, designed for high-efficiency DC/DC converter switching and notebook computer power management. It supports 4.0 V gate drive, delivers ≤32 mΩ RDS(on) at VGS = 4.0 V / ID = 4.0 A, and features integrated gate-source ESD protection diodes.
For engineers reviewing the UPA1809GR-9JG-E1-A datasheet, UPA1809GR-9JG-E1-A pinout, UPA1809GR-9JG-E1-A application, or UPA1809GR-9JG-E1-A equivalent, key selection criteria include low-voltage gate drive capability, dual-channel layout for synchronous buck topologies, RDS(on) performance at 4.0–4.5 V, thermal derating on ceramic substrates, and body diode recovery (trr = 24 ns, Qrr = 15 nC).
Technical Context
This device implements two independent N-channel enhancement-mode MOSFETs in a single Power TSSOP-8 package with shared thermal pad. Its gate threshold voltage range (VGS(off) = 1.5–2.5 V) enables reliable turn-on from 4.0 V logic rails, while the low input capacitance (Ciss = 520 pF) and fast switching (td(on) = 11.5 ns, tf = 6.1 ns) support high-frequency PWM operation up to several hundred kHz.
The integrated source-drain body diode exhibits VF(S-D) = 0.85 V at 8.0 A and fast reverse recovery (trr = 24 ns), making it suitable for synchronous rectification where external Schottky replacement is not required. Thermal design must account for 62.5°C/W transient thermal resistance on 5000 mm² ceramic substrate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage for DC/DC primary-side switch or synchronous rectifier in ≤12 V input systems. |
| RDS(on) @ VGS=4.0 V | 32 mΩ MAX - Enables efficient operation directly from 4.0 V microcontroller GPIO or PMIC gate drivers without level-shifting. |
| ID(DC) | ±8.0 A - Continuous current rating per channel at TA = 25°C on specified ceramic substrate. |
| QG | 10 nC - Total gate charge determines driver strength requirement and switching loss at target frequency. |
| trr / Qrr | 24 ns / 15 nC - Fast body diode recovery minimizes shoot-through risk and conduction loss in synchronous buck converters. |
| Ciss | 520 pF - Input capacitance impacts gate drive loop stability and required driver peak current. |
Pinout & Package
UPA1809GR-9JG-E1-A uses the Power TSSOP-8 package (6.4 mm × 4.4 mm × 1.0 mm max height) with exposed thermal pad. Pin 1 is Drain1; pins 2–3 are Source1; pin 4 is Gate1; pin 5 is Gate2; pins 6–7 are Source2; pin 8 is Drain2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Drain1 | High-side switch output node in half-bridge or synchronous buck high-side position. |
| 2,3 | Source1 | Return path for Channel 1; electrically tied to thermal pad for enhanced heat dissipation. |
| 4 | Gate1 | Control input for first N-channel MOSFET; requires 4.0–10 V drive for full enhancement. |
| 5 | Gate2 | Independent control input for second N-channel MOSFET; enables dual-switch or synchronous rectifier configuration. |
| 6,7 | Source2 | Return path for Channel 2; isolated from Source1 to support floating low-side gate drive in half-bridge. |
| 8 | Drain2 | Low-side switch output node; used as synchronous rectifier in buck converters or second switch in load switches. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7852DP-T1-GE3 | Single N-channel, SO-8, RDS(on) = 12 mΩ @ 10 V; no 4.0 V drive spec; higher Ciss (1100 pF) | Requires external level shift or 10 V gate drive; unsuitable for direct 4.0 V logic interface | Select only if system uses dedicated 10 V gate driver and needs lower RDS(on) at higher VGS. |
| DMN3022LSD-13 | Dual N-channel, SO-8, RDS(on) = 29 mΩ @ 4.5 V; no 4.0 V RDS(on) spec; trr = 35 ns (slower) | Marginally compatible for 4.5 V drive systems; higher body diode loss in synchronous rectification | Acceptable for cost-sensitive designs where 4.0 V drive is not required and 35 ns trr is acceptable. |

FAQ
What is the maximum continuous drain current rating for UPA1809GR-9JG-E1-A?
The UPA1809GR-9JG-E1-A has a rated continuous drain current (ID(DC)) of ±8.0 A per channel at TA = 25°C when mounted on a 5000 mm² ceramic substrate. Derating applies above 25°C ambient; at 75°C, usable current drops to approximately 5.5 A per channel based on the published derating curve.
Does UPA1809GR-9JG-E1-A support true 4.0 V gate drive with guaranteed RDS(on)?
Yes. The UPA1809GR-9JG-E1-A datasheet specifies RDS(on)3 = 32 mΩ MAX at VGS = 4.0 V and ID = 4.0 A. This is a production-tested maximum value-not a typical or conditional spec-making UPA1809GR-9JG-E1-A suitable for direct drive from 4.0 V logic or PMIC outputs without level shifting.
What is the purpose of the built-in gate-source protection diode in UPA1809GR-9JG-E1-A?
The built-in gate-source diode in UPA1809GR-9JG-E1-A provides electrostatic discharge (ESD) protection per human-body model (HBM). It clamps transient gate voltage spikes to prevent oxide breakdown. However, the datasheet explicitly states that an external protection circuit remains necessary if operating voltages may exceed ±20 V gate-source rating.
Can UPA1809GR-9JG-E1-A be used in synchronous rectifier configurations?
Yes. UPA1809GR-9JG-E1-A includes a body diode with VF(S-D) = 0.85 V at 8.0 A and trr = 24 ns, enabling use as a synchronous rectifier in buck converters. Its dual-channel structure allows one channel to serve as high-side switch and the other as low-side synchronous rectifier, reducing conduction loss versus Schottky diodes.
What thermal substrate is required to achieve the 2.0 W total power dissipation rating for UPA1809GR-9JG-E1-A?
The 2.0 W total power dissipation (PT) rating for UPA1809GR-9JG-E1-A assumes mounting on a ceramic substrate measuring 5000 mm² × 1.1 mm thickness. On standard FR-4 PCBs (2500 mm² × 1.6 mm), PT derates to ~1.2 W at 25°C ambient-requiring careful thermal design and potentially heatsinking for sustained 8 A operation.
