Product details

Overview

UPA2802T1L-E2-AY from Renesas Electronics is an N-channel power MOSFET designed for DC/DC converter and power management in portable equipment. It delivers R_DS(on)1 = 5.8 mΩ max at V_GS = 10 V, I_D = 18 A; R_DS(on)2 = 10 mΩ max at V_GS = 4.5 V, I_D = 9 A; and features a built-in gate protection diode in an 8-pin HVSON (3.3 × 3.3 mm) package.

For engineers reviewing the UPA2802T1L-E2-AY datasheet, UPA2802T1L-E2-AY pinout, UPA2802T1L-E2-AY application, or UPA2802T1L-E2-AY equivalent, key selection criteria include low on-resistance at 4.5 V gate drive, avalanche energy rating (E_AS = 32.4 mJ), thermal resistance (R_th(ch-C) = 2.4 °C/W), and RoHS-compliant pure Sn lead plating.

Technical Context

This MOSFET employs a trench-gate structure optimized for high-current switching with fast turn-on (t_d(on) = 14 ns) and turn-off (t_d(off) = 49 ns) times under 10 Ω gate resistance. Its body diode exhibits V_F(S-D) = 0.82–1.2 V at I_F = 18 A and t_rr = 32 ns with 100 A/μs di/dt, supporting synchronous rectification in buck converters.

The device operates within a V_DSS = 20 V rating and supports ±72 A pulsed drain current (PW ≤ 10 μs, duty ≤ 1%). Its channel-to-case thermal resistance of 2.4 °C/W enables efficient heat transfer to PCB copper when mounted on FR-4 (25.4 × 25.4 × 0.8 mm), critical for thermally constrained portable designs.

Key Specifications

V_DSS	20 V - Maximum blocking voltage suitable for 12 V input rail DC/DC stages.
R_DS(on)1	5.8 mΩ max @ V_GS = 10 V, I_D = 18 A - Enables <100 mW conduction loss at full load in compact converters.
R_DS(on)2	10 mΩ max @ V_GS = 4.5 V, I_D = 9 A - Ensures robust operation with 5 V or single-cell Li-ion gate drive.
E_AS	32.4 mJ - Withstands single-pulse inductive energy during hard-switching or fault events without failure.
Q_G	16 nC - Low gate charge reduces driver power requirement and improves switching efficiency at >500 kHz.
R_th(ch-C)	2.4 °C/W - Direct thermal path to drain pad allows >1.5 W continuous dissipation with minimal board area.
I_D(DC)	±18 A - Rated continuous current supports high-density power stages in space-constrained applications.

Pinout & Package

UPA2802T1L-E2-AY uses an 8-pin HVSON (3.3 × 3.3 mm, 0.65 mm pitch) package with exposed drain paddle for thermal and electrical performance. The package conforms to JEDEC MO-229 standard and features pure Sn lead finish.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Source	Common source connection for internal parallel FET cells; low-inductance tie to ground plane.
4	Gate	Control terminal requiring <16 nC charge; gate protection diode integrated between Gate and Source.
5, 6, 7, 8	Drain	High-current output node tied to exposed thermal pad; electrically and thermally coupled to PCB copper.

Key Features

Feature	Design Value
Low R_DS(on) at 4.5 V	10 mΩ max enables use with 5 V microcontroller GPIO or battery-powered gate drivers without level-shifting.
Built-in gate protection diode	ESD protection between gate and source per human-body model (HBM); external TVS still required for system-level surge.
Thin HVSON package	0.32 mm profile minimizes board height-critical for ultra-thin smartphones and wearables.
Avalanche-rated	Rated for single-pulse I_AS = 18 A and E_AS = 32.4 mJ, supporting reliable operation in non-synchronous flyback or boost topologies.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si2302DS-T1-GE3	R_DS(on) = 50 mΩ @ 4.5 V; SOT-23 package; lower current rating (I_D = 3.2 A).	Suitable only for sub-1 A loads; lacks avalanche rating and thermal performance for DC/DC primary switches.	Select only for low-power load switching where size and cost outweigh efficiency and ruggedness requirements.
AO3400	R_DS(on) = 28 mΩ @ 4.5 V; same 8-pin SO-8 footprint but larger thermal resistance (R_th(j-a) ≈ 60 °C/W).	Requires larger PCB copper area for equivalent thermal performance; not optimized for ultra-thin portable designs.	Prefer when existing SO-8 layout exists and 28 mΩ R_DS(on) meets efficiency targets at lower cost.

Compared with Si2302DS-T1-GE3 and AO3400, UPA2802T1L-E2-AY provides superior conduction efficiency at 4.5 V gate drive, significantly lower thermal resistance, and guaranteed avalanche capability-making it uniquely suited for high-density, high-reliability portable DC/DC converters.

FAQ

What is the maximum continuous drain current rating for UPA2802T1L-E2-AY?

The UPA2802T1L-E2-AY is rated for ±18 A DC drain current at T_A = 25°C with all terminals connected and mounted on a standard FR-4 board (25.4 × 25.4 × 0.8 mm). Derating applies above 25°C ambient, and actual usable current depends on PCB copper area, airflow, and thermal interface to the drain pad. The UPA2802T1L-E2-AY must be operated within its safe operating area defined by V_DS, I_D, and pulse width limits.

Does UPA2802T1L-E2-AY have built-in ESD protection?

Yes, the UPA2802T1L-E2-AY integrates a gate-to-source protection diode to guard against electrostatic discharge per human-body model (HBM). However, Renesas explicitly states that this internal diode serves only as a basic protector and that an external protection circuit remains mandatory if voltages exceeding the rated ±20 V gate-to-source limit may occur in the system. The UPA2802T1L-E2-AY datasheet confirms this requirement in the "Remark" section of the Absolute Maximum Ratings table.

What is the thermal resistance from channel to case for UPA2802T1L-E2-AY?

The channel-to-case thermal resistance (R_th(ch-C)) of UPA2802T1L-E2-AY is 2.4 °C/W, measured from the silicon channel to the exposed drain paddle. This value assumes proper soldering of the drain pad to a minimum 25.4 × 25.4 mm copper area on FR-4. The low R_th(ch-C) enables efficient heat transfer directly into the PCB, allowing UPA2802T1L-E2-AY to sustain higher power dissipation than conventional SO-8 or SOT-23 packages under identical conditions.

Can UPA2802T1L-E2-AY be used in avalanche mode?

Yes, UPA2802T1L-E2-AY is fully specified for single-pulse avalanche operation with I_AS = 18 A and E_AS = 32.4 mJ under defined test conditions (V_DD = 10 V, R_G = 25 Ω, L = 100 μH, starting T_ch = 25°C). This rating permits controlled energy absorption during inductive switching transients, making UPA2802T1L-E2-AY suitable for non-synchronous flyback or boost converters where the body diode conducts during dead time.

What is the gate threshold voltage range for UPA2802T1L-E2-AY?

The gate-to-source cutoff voltage (V_GS(off)) of UPA2802T1L-E2-AY is specified from 1.0 V to 2.5 V at V_DS = 10 V and I_D = 1 mA. This threshold range ensures reliable turn-on with standard 3.3 V or 5 V logic-level gate drivers while maintaining low leakage (I_DSS ≤ 10 μA at V_DS = 20 V). The UPA2802T1L-E2-AY's typical forward transfer admittance |y_fs| of 6 S further confirms strong transconductance across its operating region.
