Product details

Overview

UPA1808GR-9JG-E1-A from Renesas Electronics (formerly NEC) is an N-channel MOSFET optimized for high-efficiency DC/DC converter switching in notebook computer power management. It features 30 V VDSS, 9.5 A continuous drain current, 17 mΩ RDS(on) at VGS = 10 V, 4.0 V logic-level gate drive capability, and integrated gate-source ESD protection diode.

For engineers reviewing the UPA1808GR-9JG-E1-A datasheet, UPA1808GR-9JG-E1-A pinout, UPA1808GR-9JG-E1-A application, or UPA1808GR-9JG-E1-A equivalent, key selection criteria include low RDS(on) at 4.0–4.5 V gate drive, pulse-rated 38 A drain current, transient thermal resistance of 62.5°C/W on ceramic substrate, and Power TSSOP8 package compatibility with space-constrained portable power stages.

Technical Context

The UPA1808GR-9JG-E1-A employs a planar vertical DMOS structure enabling direct 4.0 V microcontroller-compatible gate drive without level-shifting. Its RDS(on) remains ≤26 mΩ even at VGS = 4.0 V and ID = 5.0 A, supporting efficient synchronous rectification in buck converters.

Switching performance is defined by 13.5 ns turn-on delay, 5.6 ns rise time, 38 ns turn-off delay, and 7.9 ns fall time under VDD = 15 V, ID = 5.0 A, and RG = 10 Ω conditions. The body diode exhibits 0.84 V forward voltage at 9.5 A and 27 ns reverse recovery time, critical for freewheeling path integrity.

Key Specifications

Parameter Value and Actual Design Meaning
VDSS 30 V - Maximum blocking voltage for 12 V input rail DC/DC stages with margin
RDS(on) @ VGS = 4.0 V 26 mΩ max - Enables <1 W conduction loss at 5 A in compact notebook power rails
ID(DC) ±9.5 A - Continuous current rating suitable for CPU core VRM output stages
QG 13 nC - Gate charge compatible with standard PWM controller drivers at ≤1 MHz
tr/tf 5.6 ns / 7.9 ns - Fast edge rates minimize switching losses in high-frequency converters
VGS(off) 1.5–2.5 V - Threshold ensures reliable turn-off with 3.3 V logic-level control signals
Ciss 660 pF - Input capacitance supports stable gate drive with low-impedance source

Pinout & Package

UPA1808GR-9JG-E1-A is housed in a Power TSSOP8 package (6.4 mm × 4.4 mm × 1.2 mm max), thermally enhanced with exposed drain paddle for PCB heat spreading. Pin 1–3 are Source, Pin 4 is Gate, and Pins 5–8 are Drain-connected terminals.

Pin/Terminal Circuit Role Design Meaning
1, 2, 3 Source Common source node for internal MOSFET cells; connects to power ground plane
4 Gate Control terminal requiring ≤13 nC charge for full enhancement; protected by built-in G-S diode
5, 6, 7, 8 Drain High-current output node tied to internal drain metallization; electrically and thermally connected to exposed paddle

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
Si2308DS-T1-GE3 RDS(on) = 28 mΩ @ VGS = 4.5 V; 20 V VDSS; SOT-23 package; lower QG (7.5 nC) Limited to ≤12 V input rails; unsuitable for 19 V notebook adapters or USB-C PD 20 V Select when board space is constrained and voltage stress is ≤15 V; verify thermal derating on FR-4
AO3414 RDS(on) = 22 mΩ @ VGS = 4.5 V; 20 V VDSS; SO-8 package; no integrated G-S diode Requires external ESD protection; lower voltage rating restricts use in higher-input DC/DC designs Prefer where cost sensitivity outweighs need for built-in ESD protection and 30 V margin

Compared with Si2308DS-T1-GE3 and AO3414, the UPA1808GR-9JG-E1-A delivers superior 30 V blocking capability and integrated gate protection-critical for unregulated 19 V adapter inputs-while maintaining competitive RDS(on) at 4.0–4.5 V drive, making it uniquely suited for notebook and USB-C PD power stages requiring both voltage margin and logic-level compatibility.

FAQ

What is the maximum continuous drain current rating for UPA1808GR-9JG-E1-A?

The UPA1808GR-9JG-E1-A has a rated continuous drain current (ID(DC)) of ±9.5 A at TA = 25°C when mounted on a 5000 mm² ceramic substrate. Derating applies above 25°C ambient per the datasheet's total power dissipation curve, dropping to ~5.5 A at 75°C ambient under the same mounting condition.

Does UPA1808GR-9JG-E1-A support 3.3 V gate drive?

The UPA1808GR-9JG-E1-A is specified for 4.0 V gate drive, with RDS(on) = 26 mΩ max at VGS = 4.0 V and ID = 5.0 A. While it may partially enhance at 3.3 V, the datasheet does not guarantee performance below 4.0 V; operation at 3.3 V risks excessive RDS(on) and thermal runaway under load. Use only with ≥4.0 V gate drive.

What is the purpose of the built-in gate-source protection diode in UPA1808GR-9JG-E1-A?

The built-in gate-source diode in the UPA1808GR-9JG-E1-A provides electrostatic discharge (ESD) protection per HBM Class 2 (≥2 kV). It clamps transient gate voltage spikes but is not intended as the sole protection against overvoltage; the datasheet explicitly states that external protection is required if voltages exceeding ±20 V VGSS may occur in the system.

Can UPA1808GR-9JG-E1-A be used in synchronous rectification topologies?

Yes, the UPA1808GR-9JG-E1-A is suitable for synchronous rectification due to its low RDS(on) (17 mΩ max at VGS = 10 V), fast switching times (tr = 5.6 ns, tf = 7.9 ns), and well-characterized body diode (trr = 27 ns, Qrr = 19 nC). Its 30 V VDSS rating supports common 12 V and 19 V input buck converters.

What is the thermal resistance from channel to ambient for UPA1808GR-9JG-E1-A?

The UPA1808GR-9JG-E1-A has a transient thermal resistance (rth(ch–A)) of 62.5°C/W for single-pulse operation when mounted on a 5000 mm² × 1.1 mm ceramic substrate. On standard FR-4 (2500 mm² × 1.6 mm), rth(ch–A) rises to 125°C/W. Steady-state θJA is not specified; design must rely on transient curves and derating graphs.
