High-Performance Power Management with STMicroelectronics STPS8170DEE-TR Schottky Diode

Engineered for demanding power applications, the STMicroelectronics STPS8170DEE-TR Schottky Diode delivers exceptional performance in a compact PowerFlat™ package. With its 170V blocking voltage and 8A average rectified current capability, this diode combines robust power handling with ultra-fast recovery characteristics. Designed for modern electronics requiring efficient thermal management and space-saving solutions, this component represents the latest advancements in Schottky diode technology.

Advanced Technical Specifications

At its core, the STPS8170DEE-TR features a cutting-edge Schottky barrier rectifier design optimized for high-frequency switching applications. The device maintains a maximum forward voltage drop of just 900mV at 8A current, significantly reducing conduction losses compared to conventional diodes. Its 170V maximum reverse voltage rating ensures reliable operation in demanding power circuits, while the surface-mount PowerFlat™ (3.3x3.3mm) package enables efficient heat dissipation without compromising board space.

Optimized for Modern Power Systems

This fourth-generation Schottky diode excels in power factor correction (PFC) circuits, DC-DC converters, and battery management systems. The PowerFlat™ package's low thermal resistance (Rth) enables reliable operation at high current densities while maintaining excellent thermal cycling performance. With its 175°C maximum junction temperature, the device offers superior thermal stability in automotive and industrial environments.

Key advantages include:

• Reduced switching losses through fast recovery characteristics
• Improved system efficiency with low forward voltage drop
• Enhanced thermal performance via exposed pad design
• High reliability in harsh operating conditions
• Compliance with RoHS and halogen-free standards

Design Flexibility and Application Scope

The STPS8170DEE-TR's versatility makes it ideal for a wide range of applications including:

- Server power supplies and telecom rectifiers
- Solar inverters and energy storage systems
- Automotive power electronics and 48V systems
- High-frequency switch-mode power supplies (SMPS)
- Industrial motor drives and automation equipment

When compared to traditional through-hole diodes, this PowerTDFN package solution offers 60% smaller board footprint while maintaining equivalent current capacity. The device's low leakage current (15µA @ 170V) ensures minimal standby losses in energy-efficient designs.

Technical Innovation and Reliability

STMicroelectronics' proprietary silicon carbide (SiC) technology enables this diode's exceptional performance characteristics. The device maintains stable electrical parameters across its entire operating temperature range, with less than 2% variation in forward voltage from -55°C to 175°C. Advanced passivation techniques ensure long-term reliability in humid environments, meeting the stringent requirements of IPC/JEDEC J-STD-002 testing.

Manufacturers benefit from simplified PCB design thanks to the component's thermal pad that doubles as a mechanical anchor. The RoHS-compliant, halogen-free construction aligns with modern environmental regulations while maintaining excellent solderability in automated assembly processes.
