Product details
Overview
UPA1820GR-9JG-E1-A from Renesas Electronics is a dual N-channel MOSFET in Power TSSOP-8 package, rated for 20 V VDSS, ±12 A DC drain current, and featuring RDS(on) as low as 6.8 mΩ at VGS = 4.5 V. It supports direct 2.5 V gate drive and integrates gate-source ESD protection diodes. It is designed for high-efficiency synchronous rectification and power switching in notebook computer DC/DC converters.
For engineers reviewing the UPA1820GR-9JG-E1-A datasheet, UPA1820GR-9JG-E1-A pinout, UPA1820GR-9JG-E1-A application, or UPA1820GR-9JG-E1-A equivalent, key selection criteria include its dual-channel layout, 2.5 V logic-level drivability, low RDS(on) at sub-4.5 V gate bias, integrated G-S ESD diode, and thermal performance on ceramic substrates.
Technical Context
The UPA1820GR-9JG-E1-A integrates two independent N-channel enhancement-mode MOSFETs in a single Power TSSOP-8 package with shared source terminals per channel (pins 2–3 = Source1, pins 6–7 = Source2). Its gate threshold voltage VGS(off) ranges from 0.5 V to 1.5 V, enabling reliable turn-on with 2.5 V logic. The device exhibits fast switching with td(on) = 18 ns and tf = 52 ns under specified test conditions.
It features a built-in gate-source protection diode per channel but requires external overvoltage protection when subjected to transients exceeding ±12 V VGSS. Its safe operating area (SOA) is defined up to 100 ms pulse width at TA = 25°C on ceramic substrate, with RDS(on) limited conduction boundary dominating at high VDS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20 V - Maximum blocking voltage before avalanche; sets upper limit for input/output rail in buck converter top/bottom switches. |
| RDS(on) @ VGS = 4.5 V | 6.8 mΩ (typ), 8.6 mΩ (max) - Enables <100 mW conduction loss at 6 A DC, critical for thermally constrained notebook power stages. |
| ID(DC) | ±12 A - Continuous current rating per channel; defines maximum steady-state load handling without derating on ceramic substrate. |
| QG | 27 nC - Total gate charge determines driver strength requirement; compatible with standard PWM controller gate drivers. |
| tr/tf | 56 ns / 52 ns - Fast edge rates reduce switching losses in high-frequency (≥300 kHz) DC/DC designs. |
| VGS(th) | 0.5–1.5 V - Low threshold enables full enhancement with 2.5 V logic supply, eliminating level-shifting in compact systems. |
| Ciss | 2020 pF - Input capacitance impacts gate drive loop stability and Miller effect during hard switching. |
Pinout & Package
UPA1820GR-9JG-E1-A is housed in a Power TSSOP-8 package (6.4 mm × 4.4 mm × 1.0 mm max height) with exposed drain pads for thermal enhancement. Pin 1 and Pin 8 are Drain1 and Drain2 respectively; pins 2–3 form Source1, pins 6–7 form Source2; pins 4 and 5 are Gate1 and Gate2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Drain1 | Main current path for Channel 1; electrically connected to exposed pad for thermal conduction to PCB. |
| 2, 3 | Source1 | Reference node for Channel 1; tied to local ground or low-side switch node in synchronous buck configuration. |
| 4 | Gate1 | Control terminal for Channel 1; requires ≤12 V drive; protected by internal G-S diode. |
| 5 | Gate2 | Independent control terminal for Channel 2; enables dual-switching or parallel operation without cross-talk. |
| 6, 7 | Source2 | Reference node for Channel 2; may be tied to Source1 for paralleling or kept separate for isolated half-bridge use. |
| 8 | Drain2 | Main current path for Channel 2; symmetric layout to Pin 1 for balanced thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| 2.5 V logic-compatible gate drive | Guarantees full enhancement at VGS = 2.5 V (RDS(on) ≤ 12 mΩ), enabling direct interface with low-voltage microcontrollers and PMICs. |
| Dual N-channel topology in single package | Reduces board space and layout complexity in synchronous rectifier or dual-phase DC/DC applications versus discrete solutions. |
| Built-in gate-source ESD protection diodes | Provides Class 2 HBM ESD robustness (per datasheet note), reducing need for external TVS in non-harsh environments. |
| Low QGD/QG ratio (13 nC / 27 nC) | Minimizes Miller-induced shoot-through risk during hard switching, improving reliability in high-dV/dt applications. |
| Thermally optimized Power TSSOP-8 | Exposed drain pads allow >1.5 W dissipation on 5000 mm² ceramic substrate, supporting compact high-power density designs. |

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 | 30 V VDSS, RDS(on) = 9.5 mΩ @ 4.5 V, SO-8 package, no integrated G-S diode. | Higher voltage rating suits 24 V industrial rails; lacks on-chip ESD protection requiring external diodes. | Select when higher blocking voltage or SO-8 footprint compatibility is required; verify external ESD protection. |
| DMN3022LSD-13 | 30 V VDSS, RDS(on) = 12.5 mΩ @ 4.5 V, dual N-channel in SO-8, no G-S diode, QG = 11 nC. | Lower gate charge reduces driver loading but higher RDS(on) increases conduction loss at >5 A. | Prefer for lower-power, high-frequency applications where gate drive strength is limited; not suitable for 12 A DC loads. |
Compared with Si7852DP-T1-GE3 and DMN3022LSD-13, the UPA1820GR-9JG-E1-A offers superior 2.5 V drive capability and integrated ESD protection-critical for space-constrained, low-voltage notebook power stages-while trading off voltage rating and gate charge for lower on-resistance at mid-range gate voltages.

FAQ
What is the maximum continuous drain current rating for UPA1820GR-9JG-E1-A?
The UPA1820GR-9JG-E1-A is rated for ±12 A DC drain current per channel at TA = 25°C when mounted on a 5000 mm² ceramic substrate. This rating assumes proper thermal management; derating is required above 25°C ambient or on FR-4 boards. The device's RDS(on) and SOA curves must be consulted to confirm safe operation under actual board-level thermal conditions for UPA1820GR-9JG-E1-A.
Does UPA1820GR-9JG-E1-A support true 2.5 V gate drive across its full current range?
Yes - the UPA1820GR-9JG-E1-A guarantees RDS(on) ≤ 12 mΩ at VGS = 2.5 V and ID = 6.0 A, confirming full enhancement at 2.5 V logic levels. Its VGS(off) range (0.5–1.5 V) ensures robust turn-on margin. This makes UPA1820GR-9JG-E1-A suitable for direct drive from 2.5 V GPIOs or low-voltage PMIC outputs without level shifting.
What is the purpose of the internal gate-source protection diode in UPA1820GR-9JG-E1-A?
The internal gate-source diode in UPA1820GR-9JG-E1-A provides electrostatic discharge (ESD) protection per the datasheet's Class 2 HBM specification. It clamps transient gate overvoltage but does not replace external protection when sustained overvoltage (>±12 V) or fast transients are expected. Designers must still implement external TVS or RC networks for robust system-level ESD immunity in UPA1820GR-9JG-E1-A applications.
Can UPA1820GR-9JG-E1-A be used in synchronous rectifier configurations?
Yes - UPA1820GR-9JG-E1-A is explicitly designed for synchronous rectification in DC/DC converters. Its low RDS(on), fast switching (tf = 52 ns), and matched dual-channel structure allow efficient replacement of Schottky diodes in buck, boost, and flyback topologies. The body diode VF(S-D) = 0.81 V at 12 A further supports low-loss freewheeling in UPA1820GR-9JG-E1-A-based synchronous rectifiers.
Is UPA1820GR-9JG-E1-A qualified for automotive applications?
No - UPA1820GR-9JG-E1-A is classified as a "Standard" quality grade device per Renesas documentation, intended for computers, office equipment, and consumer electronics. It is not AEC-Q101 qualified and lacks automotive-specific stress testing, failure rate data, or extended temperature support. For automotive use, designers must select Renesas' "High Quality" or AEC-Q101-certified alternatives instead of UPA1820GR-9JG-E1-A.
