Product details

Overview

UPA2718GR-E2-AT from Renesas Electronics is a P-channel power MOSFET designed for Li-ion battery protection circuits and notebook computer power management. It delivers R_DS(on) = 9.0 mΩ max at V_GS = −10 V / I_D = −6.5 A, supports −30 V drain-to-source voltage, and features built-in gate protection diode in Power SOP8 package.

For engineers reviewing the UPA2718GR-E2-AT datasheet, UPA2718GR-E2-AT pinout, UPA2718GR-E2-AT application, or UPA2718GR-E2-AT equivalent, key selection criteria include low-voltage gate drive capability (R_DS(on) = 14.5 mΩ max at V_GS = −4.5 V), avalanche energy rating (E_AS = 16.9 mJ), and surface-mount Power SOP8 thermal performance on ceramic substrate.

Technical Context

This device operates as a high-side load switch in battery protection ICs, using depletion-mode-compatible gate threshold (V_GS(off) = −1.0 to −2.5 V) to enable direct control by logic-level signals. Its low C_iss (2810 pF typ.) and fast switching (t_d(on) = 13 ns, t_f = 310 ns) support efficient pulsed operation in overcurrent and short-circuit protection circuits.

The integrated body diode provides reverse-polarity protection with V_F(S-D) = 0.84 V at I_F = 13 A and t_rr = 180 ns, while single-pulse avalanche capability (I_AS = −13 A, E_AS = 16.9 mJ) ensures robustness during transient fault events in portable power systems.

Key Specifications

V_DSS	−30 V: Maximum blocking voltage for Li-ion battery stack (up to 3S configuration).
R_DS(on)1	9.0 mΩ max at V_GS = −10 V / I_D = −6.5 A: Enables <100 mW conduction loss at 6.5 A DC load current.
R_DS(on)2	14.5 mΩ max at V_GS = −4.5 V / I_D = −6.5 A: Supports direct interface with 4.5 V logic or battery monitor outputs.
C_iss	2810 pF typ. at V_DS = −10 V: Limits gate drive power and enables use with low-current protection controllers.
E_AS	16.9 mJ: Withstands single inductive energy dump (e.g., motor stall or cable disconnect) without failure.
T_ch max	150 °C: Specifies maximum junction temperature for continuous operation in thermally constrained notebooks.
Q_G	67 nC: Determines minimum gate driver current required for 100 ns switching transitions.

Pinout & Package

UPA2718GR-E2-AT uses Power SOP8 (also known as PSOP8 or SOP-8L) package: 4.4 mm × 5.37 mm footprint, 1.8 mm height, 1.27 mm lead pitch, with exposed drain pad for thermal enhancement.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Source	Main current return path; tied to battery negative or system ground in high-side switch configuration.
4	Gate	Control input requiring negative voltage relative to source to turn on; protected by internal Zener diode.
5, 6, 7, 8	Drain	High-current output node connected to battery positive; electrically and thermally linked to exposed pad.

Key Features

Feature	Design Value
Low R_DS(on) at −4.5 V	14.5 mΩ max enables direct drive from 4.5 V battery monitor ICs without level-shifting circuitry.
Built-in gate protection diode	Integrated Zener clamps gate-to-source voltage to ±20 V, reducing external ESD protection component count.
Small Power SOP8 package	Surface-mount 8-pin outline with exposed drain pad improves thermal resistance (R_th(ch–A) = 62°C/W on ceramic substrate).
Fast body diode recovery	t_rr = 180 ns and Q_rr = 14 nC minimize switching losses and voltage spikes in bidirectional current paths.
Avalanche-rated operation	Rated for single-pulse I_AS = −13 A and E_AS = 16.9 mJ, supporting reliable fault handling in portable equipment.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si2301DDS-T1-GE3	R_DS(on) = 115 mΩ @ V_GS = −4.5 V; SOT-23 package; lower current rating (−2.7 A DC).	Suitable only for sub-3 A protection loads; lacks avalanche rating and thermal capacity for notebook main battery switches.	Select only for space-constrained, low-power battery packs where 115 mΩ on-resistance is acceptable.
AO3401	R_DS(on) = 55 mΩ @ V_GS = −4.5 V; SO-8 package; no specified E_AS rating.	Acceptable for basic load switching but not recommended for critical battery protection where fault energy must be absorbed.	Prefer for cost-sensitive, non-avalanche-requiring applications; verify thermal margin on PCB with 25.4 mm × 25.4 mm FR4.

Compared with Si2301DDS-T1-GE3 and AO3401, UPA2718GR-E2-AT offers superior conduction efficiency (9.0 mΩ vs. ≥55 mΩ), certified avalanche ruggedness, and Power SOP8 thermal performance-making it uniquely suited for primary Li-ion battery protection in portable computing.

FAQ

What is the maximum continuous drain current rating for UPA2718GR-E2-AT?

The UPA2718GR-E2-AT has a DC drain current rating of −13 A at T_A = 25°C when mounted on a ceramic substrate (1200 mm² × 2.2 mm). Derating applies above 25°C ambient; at 75°C, the usable DC current drops to approximately −7.5 A per the published derating curve in the datasheet.

Does UPA2718GR-E2-AT support gate drive from a 3.3 V microcontroller?

No-UPA2718GR-E2-AT requires negative gate-to-source voltage to conduct; its R_DS(on) is not characterized below V_GS = −4.5 V. At −3.3 V, conduction is marginal and R_DS(on) exceeds 25 mΩ. A dedicated gate driver or level shifter generating at least −4.5 V relative to source is required for reliable operation.

Is the gate protection diode in UPA2718GR-E2-AT sufficient for system-level ESD compliance?

The internal gate protection diode in UPA2718GR-E2-AT clamps V_GS to ±20 V and handles typical board-level ESD transients, but it does not meet IEC 61000-4-2 Level 4 (±15 kV air/±8 kV contact). External TVS diodes remain necessary for full system ESD robustness in end-product certification.

Can UPA2718GR-E2-AT be used in parallel configurations for higher current handling?

Yes-UPA2718GR-E2-AT exhibits positive temperature coefficient for R_DS(on), enabling stable current sharing when paralleled. However, layout symmetry (matched gate trace inductance, equal source/drain loop area) and individual gate resistors (≥10 Ω) are mandatory to prevent oscillation and ensure balanced dynamic current distribution during switching.

What is the thermal resistance from channel to ambient for UPA2718GR-E2-AT on standard FR4 PCB?

When mounted on a 25.4 mm × 25.4 mm × 0.8 mm glass epoxy board, UPA2718GR-E2-AT has R_th(ch–A) = 120°C/W (per datasheet Note 3). This value assumes 10-second pulse width and defines safe operating area limits-continuous operation at rated power requires active cooling or larger copper areas beyond the reference board.
