Engineered for efficiency, this diode features fast recovery characteristics (<30 ns) that minimize switching losses in high-frequency circuits. Its surface-mount SMB package enables automated PCB assembly while maintaining excellent thermal dissipation capabilities. The device's 1.05 V forward voltage drop at full load ensures minimal power loss, translating to improved system efficiency and reduced heat generation.
Design Advantages and Applications
The STTH4R02U's combination of 200V blocking capability and 4A current rating makes it particularly suitable for:
• Switch-mode power supplies (SMPS)
• Motor control circuits
• Industrial automation systems
• Automotive electronics
• Renewable energy inverters
Its high junction temperature rating (175°C) provides exceptional reliability in harsh environments, while the 3 µA reverse leakage current at maximum voltage ensures minimal standby power consumption. The device's fast recovery time enables efficient operation in circuits switching at frequencies exceeding 100 kHz.
Technical Excellence in Power Electronics
STMicroelectronics' proprietary silicon technology delivers consistent performance across the device's operating range. The STTH4R02U maintains stable electrical characteristics even under thermal stress, with minimal parameter drift between 25°C and 175°C operating temperatures. This stability makes it particularly valuable in:
• Power factor correction (PFC) circuits
• DC-DC converters
• Battery charging systems
• High-voltage motor drives
The SMB package (equivalent to DO-214AA) offers excellent mechanical robustness while maintaining industry-standard footprint compatibility. This allows designers to easily integrate the STTH4R02U into existing layouts without requiring extensive PCB redesign.
Quality and Reliability
As part of STMicroelectronics' industrial-grade component portfolio, the STTH4R02U undergoes rigorous testing to ensure compliance with:
• JEDEC qualification standards
• AEC-Q101 automotive requirements
• RoHS/REACH environmental regulations
This quality assurance makes it suitable for mission-critical applications where component failure could have significant operational consequences.
