BTW67-1000

BTW67-1000 Description

The BTW67-1000 from STMicroelectronics is a high-performance Standard Recovery SCR (Silicon Controlled Rectifier) designed for robust power control applications. With a 1 kV off-state voltage and 50 A RMS on-state current, it delivers reliable switching capabilities in high-voltage, high-current environments. The device features a low gate trigger voltage (Vgt) of 1.3 V max and a hold current (Ih) of 150 mA max, ensuring efficient triggering and stable conduction. Its low on-state voltage drop (Vtm) of 1.9 V max minimizes power dissipation, enhancing thermal performance. Packaged in RD91 (Chassis Mount), it is built for durability and ease of integration in industrial systems.

BTW67-1000 Features

• High Voltage & Current Handling: Supports 1 kV blocking voltage and 50 A RMS continuous current, with surge capabilities up to 580 A (50Hz) / 610 A (60Hz).
• Low Trigger Requirements: 1.3 V gate trigger (Vgt) and 80 mA gate current (Igt) ensure easy drive compatibility.
• Efficient Power Management: 1.9 V max on-state voltage (Vtm) reduces conduction losses.
• Robust Construction: Chassis-mount RD91 package for high mechanical and thermal stability.
• Compliance & Reliability: ROHS3 compliant, REACH unaffected, and MSL 1 (unlimited) for environmental resilience.
