Product details
Overview
SPV1001D40TR from STMicroelectronics is a smart bypass switch IC for photovoltaic panel strings, implementing active MOSFET-based rectification with 16 A forward current rating, 40 V reverse voltage capability, and 230 mV typical average forward voltage drop at 16 A and 25 °C. It replaces Schottky diodes in solar module bypass circuits to suppress hot-spot heating under partial shading.
For engineers reviewing the SPV1001D40TR datasheet, SPV1001D40TR pinout, SPV1001D40TR application, or SPV1001D40TR equivalent, key selection criteria include its ultra-low VF,AVG (≤230 mV @16A), <1 µA reverse leakage at 25 °C, 175 °C max junction temperature, D²PAK package thermal resistance (1.5 °C/W), and self-powered gate drive architecture.
Technical Context
The SPV1001D40TR integrates a power MOSFET and charge-pump gate driver in a single D²PAK package, eliminating external biasing. It operates in a self-oscillating mode where the MOSFET charges an internal capacitor during OFF time and uses that stored charge to drive its own gate during ON time.
This architecture achieves a 95% duty cycle at 8 A and 25 °C, reducing average conduction loss. The device maintains low VF,AVG across temperature (270 mV @16 A, 125 °C) and exhibits <10 µA IR at 125 °C, enabling reliable operation in high-temperature rooftop PV installations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (max) | 16 A continuous forward current - supports standard 60-cell and 72-cell PV string configurations |
| VR (max) | 40 V DC reverse voltage - compatible with ≤36 V nominal PV string open-circuit voltage |
| VF,AVG @16A/25°C | 230 mV typical - reduces power loss by >60% vs. Schottky diodes (~600–800 mV) |
| IR @40V/25°C | 1 µA max - minimizes parasitic shunt current in shaded cell strings |
| RthJC | 1.5 °C/W - enables compact heatsinking on FR4 PCBs with ≥10 cm² copper area |
| TJ operating range | −40 to +175 °C - rated for outdoor PV mounting without derating up to ambient 85 °C |
Pinout & Package
The SPV1001D40TR is housed in a surface-mount D²PAK (TO-263) package with exposed drain tab for thermal conduction. Pin 1 = Source, Pin 2 = Drain (tab), Pin 3 = NC (no internal connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Power return path | Connected to cathode side of PV string; carries full forward current |
| Pin 2 (Drain / Tab) | Main power switch node | Exposed metal tab serves as drain terminal and primary thermal interface to PCB copper |
| Pin 3 (NC) | No internal connection | Not bonded; must be left floating or tied to source for mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Self-powered gate drive | Eliminates need for external bias supply or auxiliary winding - simplifies PV module integration |
| Ultra-low VF,AVG | 230 mV @16 A, 25 °C - directly lowers thermal stress and improves energy harvest under shading |
| Low IR at high temperature | 10 µA @40 V, 125 °C - prevents thermal runaway in hot-climate installations |
| D²PAK thermal performance | 1.5 °C/W RthJC - allows >12 W dissipation with 25 °C ambient rise using 10 cm² 2-oz Cu |
Applications
| Photovoltaic Bypass Protection | Commercial Rooftop Solar Arrays |

Equivalent & Alternatives
The following parts are listed as comparable options for similar photovoltaic bypass switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SI7850DP-T1-GE3 | Discrete N-channel MOSFET only; requires external gate driver and bootstrap capacitor | Lacks integrated charge pump; increases BOM count and layout complexity | Preferred when custom timing control or higher voltage (>60 V) is needed |
| Diodes Inc. DSSK30-0025 | Schottky diode with 250 mV VF @15 A, 25 °C and 50 µA IR @40 V, 25 °C | No active control; fixed forward drop and higher leakage accelerates hot-spot formation | Used where cost sensitivity outweighs efficiency and reliability requirements |
Compared with SI7850DP-T1-GE3 and DSSK30-0025, the SPV1001D40TR delivers lower conduction loss, superior thermal margin, and system-level simplification through monolithic integration - making it optimal for premium PV modules targeting IEC 61215 certification and 30-year warranties.

FAQ
What is the recommended PCB layout for thermal management of SPV1001D40TR?
Use ≥10 cm² of 2-ounce copper connected directly to the exposed drain tab (Pin 2) with ≥6 thermal vias (0.3 mm diameter, 0.6 mm pitch). Avoid solder mask over the tab area. Maintain ≥1.5 mm clearance from adjacent components to prevent localized heating. This layout achieves the specified 1.5 °C/W RthJC and supports 12 W continuous dissipation at 25 °C ambient.
Does SPV1001D40TR require external gate drive components?
No. The SPV1001D40TR integrates a self-contained charge-pump gate driver that stores energy during OFF time and applies it to the MOSFET gate during ON time. No external capacitors, resistors, or bias supplies are required - only the three terminals (Source, Drain, NC) must be connected per the datasheet layout guidelines.
How does SPV1001D40TR behave under partial shading conditions?
Under shading, the device automatically enters blocking mode with <1 µA reverse leakage at 25 °C and <10 µA at 125 °C. Its low VF,AVG ensures minimal forward conduction loss when bypassing shaded substrings, preventing localized overheating and preserving string-level power output - validated per IEC 61215 hot-spot endurance testing protocols.
Is SPV1001D40TR compliant with RoHS and REACH regulations?
Yes. SPV1001D40TR is manufactured in STMicroelectronics' ECOPACK®-compliant D²PAK package, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full material declarations and compliance documentation are available via ST's official product page and authorized distribution channels.
