Product details
Overview
UPA1815GR-9JG-E1-A from Renesas Electronics is a P-channel enhancement-mode MOSFET designed for low-voltage switching applications, featuring RDS(on) = 15 mΩ max at VGS = –4.5 V and ID = –3.5 A, ±20 V drain-source voltage rating, and Power TSSOP8 package. It is optimized for power switches in portable electronics requiring direct 2.5-V gate drive compatibility.
For engineers reviewing the UPA1815GR-9JG-E1-A datasheet, UPA1815GR-9JG-E1-A pinout, UPA1815GR-9JG-E1-A application, or UPA1815GR-9JG-E1-A equivalent, key selection criteria include low-threshold gate drive capability (–2.5 V operational), body diode recovery performance (trr = 60 ns), and thermal derating on ceramic substrate - critical for compact DC-DC load switches and battery protection circuits.
Technical Context
This device operates as a single P-channel silicon MOSFET with integrated gate-source ESD protection diode. Its threshold voltage range (VGS(off) = –0.5 to –1.5 V) enables reliable turn-on with logic-level gate signals down to 2.5 V, while its 2.0 W total power dissipation (on 5000 mm² ceramic substrate) supports pulsed operation up to ±26 A (10 µs, 1% duty).
The device exhibits strong transconductance (|yfs| = 9–19 S), fast switching (td(on) = 45 ns, tf = 160 ns), and controlled capacitive behavior (Ciss = 3000 pF, Coss = 790 pF), making it suitable for synchronous rectification and high-side load switching where gate charge (QG = 25 nC) and reverse recovery (Qrr = 45 nC) directly impact efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | –20 V: Maximum blocking voltage for use in ≤20-V rail systems like USB PD, Li-ion battery packs, and 12-V industrial I/O. |
| RDS(on) @ VGS = –4.5 V | 15 mΩ max: Enables <100 mW conduction loss at 3.5 A, supporting thermally constrained portable PCB layouts. |
| ID(DC) | ±7 A: Continuous current rating defining safe steady-state operation with appropriate heatsinking. |
| trr | 60 ns: Body diode reverse recovery time enabling use in discontinuous-conduction-mode (DCM) flyback or buck converters without excessive ringing. |
| QG | 25 nC: Total gate charge determining required driver strength and switching loss in high-frequency (>100 kHz) applications. |
| Tch max | 150 °C: Maximum channel temperature limiting junction-to-ambient thermal design margin under sustained load. |
| Ciss | 3000 pF: Input capacitance influencing gate drive loop stability and Miller effect during high dv/dt transitions. |
Pinout & Package
UPA1815GR-9JG-E1-A is housed in Power TSSOP8 (8-pin thin shrink small outline package) with exposed drain pad for thermal enhancement. Pin 1, 5, and 8 are internally connected to drain; pins 2, 3, and 6 connect to source; pin 4 is gate. The package supports surface-mount assembly and requires careful layout of the drain thermal pad per Renesas' mounting guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8 | Drain | High-current output node; electrically and thermally tied to exposed pad - must be soldered to large copper area for thermal management. |
| 2, 3, 6 | Source | Reference node for gate drive and current return path; multiple pins reduce source inductance in high-di/dt switching. |
| 4 | Gate | Control input requiring low-impedance drive; internal ESD diode to source protects against ±12 V transients but external clamping recommended. |
| 7 | Source | Additional source connection - used to minimize common-source inductance in high-frequency switching paths. |
Key Features
| Feature | Design Value |
|---|---|
| 2.5-V logic-compatible gate drive | Operates fully enhanced at VGS = –2.5 V (RDS(on) ≤ 23 mΩ), eliminating need for level shifters in 3.3-V/2.5-V microcontroller interfaces. |
| Low RDS(on) with scalable VGS | RDS(on) drops from 23 mΩ at –2.5 V to 15 mΩ at –4.5 V, allowing system-level trade-off between gate drive voltage and conduction loss. |
| Fast body diode recovery | trr = 60 ns and Qrr = 45 nC enable efficient freewheeling in synchronous buck topologies without external Schottky supplementation. |
| ESD-protected gate structure | Integrated gate-source diode provides Class 2 HBM ESD robustness (per datasheet note), reducing need for external TVS in board-level protection schemes. |
| Thermally optimized Power TSSOP8 | Exposed drain pad and multi-pin source/drain configuration lower thermal resistance (rth(ch–A) = 62.5 °C/W single-pulse), supporting higher power density than standard SO-8. |
Applications
| Battery Protection Circuit | USB Type-C Power Delivery Switch |

IC Role / Device Role / Timing Role: Active rectification element replacing Schottky diode to improve efficiency at light-to-moderate loads. Use Value: Qrr = 45 nC and trr = 60 ns reduce switching losses and EMI vs. discrete diodes; low Coss maintains stable regulation under dynamic load steps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si2301DDS-T1-GE3 | RDS(on) = 115 mΩ @ –2.5 V (higher conduction loss); SOT-23 package (lower power handling). | Targeted at ultra-low-power always-on circuits (<500 mA), not high-current load switching. | Select only for space-constrained, sub-1-A applications where thermal budget permits higher RDS(on). |
| AO3401 | RDS(on) = 55 mΩ @ –2.5 V; SO-8 package; no specified trr or Qrr in datasheet. | Suitable for general-purpose load switching but lacks documented fast-recovery body diode for synchronous rectification. | Prefer for cost-sensitive, non-synchronous designs where diode recovery is not critical. |
Compared with Si2301DDS-T1-GE3 and AO3401, UPA1815GR-9JG-E1-A delivers superior conduction efficiency at 3.5 A and verified fast body diode performance - essential for high-density, thermally limited portable power architectures requiring both low loss and clean switching transitions.

FAQ
What is the maximum continuous drain current rating for UPA1815GR-9JG-E1-A?
The UPA1815GR-9JG-E1-A has a rated continuous drain current (ID(DC)) of ±7 A at TA = 25 °C when mounted on a 5000 mm² ceramic substrate. This rating decreases with rising ambient temperature per the derating curve in the datasheet, reaching zero at approximately 125 °C ambient. Actual usable current depends on PCB layout, copper area, and airflow - the UPA1815GR-9JG-E1-A must be thermally anchored via its exposed drain pad to sustain rated current.
Does UPA1815GR-9JG-E1-A support direct 2.5-V gate drive?
Yes, UPA1815GR-9JG-E1-A is explicitly characterized for 2.5-V operation: RDS(on) is guaranteed ≤23 mΩ at VGS = –2.5 V and ID = –3.5 A. Its gate threshold range (VGS(off) = –0.5 to –1.5 V) ensures full enhancement well below –2.5 V, enabling reliable switching with 2.5-V or 3.3-V logic outputs without external level shifting - a core design feature confirmed in the "FEATURES" section of the D13805EJ3V0DS datasheet.
What is the body diode reverse recovery time (trr) of UPA1815GR-9JG-E1-A?
The body diode reverse recovery time trr of UPA1815GR-9JG-E1-A is 60 ns, measured at IF = 7 A, VGS = 0 V, and di/dt = 100 A/µs. This value is specified in the "ELECTRICAL CHARACTERISTICS" table and supports use in high-frequency DC-DC converters where fast freewheeling is required. The associated Qrr is 45 nC, confirming low stored charge that reduces switching loss and voltage overshoot during commutation.
Is UPA1815GR-9JG-E1-A pin-compatible with other Power TSSOP8 P-channel MOSFETs?
No documented pin-to-pin compatibility exists between UPA1815GR-9JG-E1-A and other Power TSSOP8 P-channel MOSFETs. While the package footprint matches standard Power TSSOP8 (8-pin, 0.65-mm pitch), internal pin assignments - particularly the multi-pin drain/source configuration (pins 1/5/8 = drain; 2/3/6/7 = source) - are specific to this Renesas device. Substitution requires verification of both pin mapping and electrical parameters; UPA1815GR-9JG-E1-A must not be assumed interchangeable without schematic and layout review.
What quality grade applies to UPA1815GR-9JG-E1-A per Renesas documentation?
UPA1815GR-9JG-E1-A is classified as "Standard" quality grade per Renesas' official documentation (D13805EJ3V0DS, page 7). This designation confirms suitability for applications including portable electronics, office equipment, communications devices, and industrial robots - but excludes safety-critical, automotive, medical life-support, or aerospace uses unless explicitly requalified and approved in writing by Renesas Electronics.
