Product details
Overview
UPA1902TE-T1-AT from Renesas Electronics is an N-channel MOSFET designed for low-voltage switching applications, featuring 4.5 V gate drive capability, 30 V drain-source voltage rating, 7.0 A DC drain current, and a typical RDS(on) of 22 mΩ at VGS = 4.5 V - enabling efficient power management in portable electronics.
For engineers reviewing the UPA1902TE-T1-AT datasheet, UPA1902TE-T1-AT pinout, UPA1902TE-T1-AT application, or UPA1902TE-T1-AT equivalent, this device is selected for compact DC-DC load switching where low gate threshold, fast turn-on (16 ns), and thermally robust SC-95 packaging are critical design requirements.
Technical Context
The UPA1902TE-T1-AT employs a planar trench-gate structure optimized for low RDS(on) and fast switching with minimal gate charge (QG = 8.0 nC). Its gate threshold voltage range (1.5–2.5 V) ensures reliable enhancement-mode operation across temperature.
It integrates no built-in gate-source protection diode and requires external ESD safeguards. The body diode exhibits VF(S-D) = 0.84 V at 7.0 A, supporting synchronous rectification and reverse-current blocking in half-bridge configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum continuous drain-source blocking voltage; suitable for 24 V rail switching and USB-powered systems. |
| RDS(on) @ VGS = 4.5 V | 22 mΩ TYP - Enables ≤155 mW conduction loss at 3.5 A, reducing thermal load on small PCBs. |
| ID(DC) | ±7.0 A - Rated DC current supports sustained load switching in battery-powered peripherals. |
| QG | 8.0 nC - Low total gate charge allows fast switching with modest driver strength (e.g., MCU GPIO). |
| td(on)/tr | 16 ns / 10 ns - Short turn-on delay and rise time support >1 MHz PWM operation in compact DC-DC regulators. |
| Tch max | 150 °C - Channel temperature limit defines safe derating envelope when mounted on 50 mm × 50 mm FR-4 board. |
Pinout & Package
UPA1902TE-T1-AT is housed in the SC-95 (Mini Mold Thin Type) package - a 6-pin, surface-mount, lead-free outline measuring 2.9 mm × 1.9 mm × 0.65 mm with exposed drain pads for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Drain | Common high-current output node; electrically and thermally connected to exposed die pad for low-inductance, low-resistance heat path. |
| 3 | Gate | Control input requiring < ±100 nA leakage; sensitive to ESD - must be protected externally per datasheet caution. |
| 4 | Source | Reference node for gate drive and current sensing; tied to system ground or low-side switch return path. |
Key Features
| Feature | Design Value |
|---|---|
| 4.5 V logic-level gate drive | Operates fully enhanced from standard 5 V or 4.5 V supply rails - eliminates need for gate boosters in portable designs. |
| Low RDS(on) at low VGS | 22 mΩ typ. @ 4.5 V enables high-efficiency load switching without thermal derating in space-constrained layouts. |
| Fast switching performance | 16 ns turn-on delay + 10 ns rise time supports high-frequency DC-DC conversion with minimal switching loss. |
| Thermally optimized SC-95 package | Exposed drain pads and thin profile allow 2.0 W power dissipation on standard FR-4 - ideal for handheld PCBs. |

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 |
|---|---|---|---|
| AO3400 | RDS(on) = 28 mΩ @ 4.5 V; higher QG (12 nC); same SC-70 package but smaller thermal mass. | Limited to ≤3 A continuous due to lower PT2 (1.4 W on FR-4); less suitable for sustained 7 A loads. | Choose AO3400 only if board area is tighter than thermal margin - verify layout copper and ambient derating. |
| SI2302DS | RDS(on) = 35 mΩ @ 4.5 V; lower ID(DC) (3.2 A); TO-236AB package with inferior thermal resistance. | Not rated for 7 A DC operation; requires significant derating above 50 °C ambient. | Select SI2302DS only for cost-sensitive, low-current (<2 A), non-thermally constrained applications. |
Compared with AO3400 and SI2302DS, the UPA1902TE-T1-AT delivers superior thermal performance (2.0 W on FR-4), lower on-resistance at 4.5 V, and verified 7 A DC capability - making it the preferred choice for portable power switches demanding both current capacity and compact footprint.

FAQ
What is the maximum continuous drain current for UPA1902TE-T1-AT under standard PCB conditions?
The UPA1902TE-T1-AT supports ±7.0 A DC drain current when mounted on a 50 mm × 50 mm × 1.6 mm FR-4 board per datasheet Note 2. This rating assumes proper copper pour under the exposed drain pads and ambient temperatures ≤70 °C. At higher temperatures, derating applies - e.g., ~5.5 A at 100 °C ambient.
Does UPA1902TE-T1-AT include integrated gate protection?
No, the UPA1902TE-T1-AT does not include a built-in gate-source protection diode. As stated in the datasheet caution, it is an electrostatic-sensitive device with low ESD capability. External gate protection (e.g., Zener clamp or RC snubber) is mandatory when voltages exceeding ±20 V may occur at the gate terminal.
Can UPA1902TE-T1-AT be driven directly by a 3.3 V microcontroller GPIO?
While the UPA1902TE-T1-AT specifies RDS(on) down to 22 mΩ at VGS = 4.5 V, its gate threshold voltage (VGS(off)) ranges from 1.5–2.5 V. At 3.3 V, it will conduct but with significantly elevated RDS(on) (~45–60 mΩ), increasing conduction loss. For reliable 3.3 V drive, verify actual load current and thermal margin - or use a level-shifting driver.
What is the safe operating area (SOA) limitation for pulsed operation of UPA1902TE-T1-AT?
The UPA1902TE-T1-AT SOA curve shows single-pulse current capability up to 28 A for ≤1 ms at VDS ≤ 10 V when mounted on the specified FR-4 board. At higher VDS, current must be reduced per the RDS(on)-limited boundary. Pulse width >100 ms requires adherence to the DC derating curve.
Is UPA1902TE-T1-AT compliant with RoHS and lead-free assembly standards?
Yes, the UPA1902TE-T1-AT is RoHS-compliant and qualified for lead-free reflow soldering. Its SC-95 package uses lead-free terminations and meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 specifications - allowing unlimited floor life at ≤30 °C/60% RH.
