Product details
Overview
SI8410DB-T2-E1 from Vishay Siliconix is an N-channel 20 V TrenchFET® power MOSFET in MICRO FOOT® 1 mm × 1 mm package, delivering RDS(on) = 0.037 Ω at VGS = 4.5 V and supporting 5.7 A continuous drain current at TA = 25 °C. It serves as a high-efficiency load switch in space-constrained power management circuits.
For engineers reviewing the SI8410DB-T2-E1 datasheet, SI8410DB-T2-E1 pinout, SI8410DB-T2-E1 application, or SI8410DB-T2-E1 equivalent, this page provides verified package mapping, thermal resistance data (RthJA = 70 °C/W max), gate charge (Qg = 5.9 nC at 4.5 V), body diode recovery (trr = 15–30 ns), and validated alternatives for compact DC-DC and battery-switching designs.
Technical Context
This MOSFET employs trench-gate silicon technology optimized for low RDS(on) and fast switching in ultra-thin, lead-free MICRO FOOT® packaging. Its gate threshold voltage (VGS(th) = 0.4–0.85 V) enables compatibility with 1.8 V and 2.5 V logic-level drive, while its low Qgd/Qg ratio (0.66/5.9 nC) supports clean turn-off in high-frequency load switching.
The device features a monolithic source-drain body diode with VSD = 0.7–1.2 V at IS = 1.5 A and Qrr = 6–15 nC, making it suitable for synchronous rectification and bidirectional current paths where reverse recovery behavior must be tightly controlled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 20 V - Maximum blocking voltage for 3.3 V/5 V rail protection and battery-input switching. |
| RDS(on) @ 4.5 V | 0.037 Ω - Enables ≤210 mW conduction loss at 5.7 A, critical for thermally limited PCB layouts. |
| Qg | 5.9 nC - Low gate charge reduces driver power and allows use with microcontroller GPIOs without external buffers. |
| tr/tf | 25/10 ns - Fast edge rates support >1 MHz PWM operation in compact DC-DC converters. |
| RthJA (max) | 70 °C/W - Thermal performance on full-copper FR4 enables 1.1 W dissipation at 70 °C ambient without heatsinking. |
| VGS(th) | 0.4–0.85 V - Ensures reliable turn-on with 1.8 V logic, eliminating need for level-shifting in low-voltage systems. |
| ID (cont) | 5.7 A @ 25 °C - Sustains high peak loads in portable power rails and USB-C PD sink applications. |
Pinout & Package
MICRO FOOT® 1 mm × 1 mm package with 4 solder bumps (0.5 mm pitch); bump-side-down mounting; backside marked "8410" and lot code. Package height ≤0.548 mm enables co-placement under connectors or shields.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Bump) | Source | Primary current return path; electrically tied to exposed die backside for lowest inductance and thermal path. |
| 2 (Bump) | Source | Second parallel source connection to reduce RDS(on) and improve current sharing in high-current paths. |
| 3 (Bump) | Drain | Main power output node; connected directly to die top metallization; requires thermal pad on PCB for heat transfer. |
| 4 (Bump) | Gate | Control input; sensitive to ESD (±8 V rating); layout must minimize trace inductance to prevent ringing during fast switching. |
Key Features
| Feature | Design Value |
|---|---|
| TrenchFET® architecture | Delivers 30% lower RDS(on) vs. planar MOSFETs of same die size, enabling higher current density in 1 mm² footprint. |

| Portable Medical Sensor Node | Low-Power IoT Edge Module |
Use Scenario: Sequencing power to analog front-end, RF transceiver, and MCU subsystems during wake-up. IC Role / Device Role / Timing Role: Controlled power gate activated by real-time clock interrupt to minimize standby leakage. Use Value: IDSS ≤1 μA at 20 V ensures <100 nA system standby current contribution; small footprint saves space on 2-layer PCBs. |
Use Scenario: Managing power to BLE SoC and environmental sensors in coin-cell–powered asset trackers. IC Role / Device Role / Timing Role: Load switch toggled by microcontroller to cycle peripherals and extend battery life. Use Value: Qg = 5.9 nC enables full turn-on in <1 μs using standard GPIO, reducing active time and energy per wake cycle. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8410BD-T1-E3 | Same die, tape-and-reel variant with different packaging (7-inch reel vs. 13-inch); identical electrical specs and MICRO FOOT® 1×1 package. | No functional difference; selected when procurement requires smaller reel size or legacy inventory alignment. | Drop-in replacement for SI8410DB-T2-E1 in new designs if reel logistics favor 7-inch format. |
| DMN2016LFG-7 | Diodes Inc. 20 V N-channel MOSFET; RDS(on) = 0.032 Ω @ 4.5 V, but in 1.6 × 1.6 mm SOT-23-3 package - 2.56× larger footprint. | Higher thermal resistance (RthJA ≈ 150 °C/W) limits continuous current to ~2.5 A on same PCB layout. | Use only when MICRO FOOT® assembly capability is unavailable; expect 30% larger board area and reduced power density. |
Compared with SI8410DB-T2-E1, Si8410BD-T1-E3 offers identical performance in a different reel configuration, while DMN2016LFG-7 trades superior RDS(on) for significantly larger footprint and poorer thermal performance-making SI8410DB-T2-E1 optimal for miniaturized, thermally constrained designs.

FAQ
What is the maximum continuous drain current for SI8410DB-T2-E1 at 70 °C ambient temperature?
The SI8410DB-T2-E1 supports 4.5 A continuous drain current at TA = 70 °C when mounted on a 1" × 1" FR4 board with full copper. This rating is derived from its RthJA = 70 °C/W maximum and TJ(max) = 150 °C limit, ensuring safe operation without derating in thermally managed handheld designs. The SI8410DB-T2-E1 maintains stable RDS(on) up to 125 °C junction temperature.
Does SI8410DB-T2-E1 require a gate resistor for typical 3.3 V GPIO switching?
While the SI8410DB-T2-E1 can be driven directly by 3.3 V microcontroller GPIOs due to its low VGS(th), a 10 Ω gate resistor is recommended to dampen ringing caused by its 5.9 nC Qg and low gate impedance. This prevents false triggering and reduces EMI in densely routed PCBs. The SI8410DB-T2-E1 gate structure tolerates ±8 V, so minor overshoot remains within safe limits.
Can SI8410DB-T2-E1 be used in reverse conduction mode (source-to-drain)?
Yes-the SI8410DB-T2-E1 integrates a monolithic body diode rated for 1.5 A continuous and 20 A pulsed source-drain current, with VSD = 0.7–1.2 V and trr = 15–30 ns. This makes the SI8410DB-T2-E1 suitable for bidirectional power paths such as battery charging/discharging circuits, provided reverse voltage does not exceed 20 V and thermal limits are observed.
What is the reflow profile compliance for SI8410DB-T2-E1?
The SI8410DB-T2-E1 complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C for lead-free processes. Its MICRO FOOT® package uses Sn/Ag/Cu bumps and Ti/Ni/Ag backside plating, ensuring robust solder joint integrity. The SI8410DB-T2-E1 must not be hand-soldered-reflow-only assembly is required per Vishay specification S15-1510-Rev. B.
How does the thermal performance of SI8410DB-T2-E1 compare between full-copper and minimum-copper PCBs?
On a 1" × 1" FR4 board with full copper, the SI8410DB-T2-E1 achieves RthJA = 70 °C/W (max), enabling 1.1 W dissipation at 70 °C ambient. With minimum copper, RthJA degrades to 160 °C/W (max), limiting usable power to 0.5 W. This 2.3× thermal penalty means the SI8410DB-T2-E1 must be placed over solid ground planes in high-power applications to avoid exceeding TJ = 150 °C.
