T16xxxH Series Thyristor (SCR) - Technical Summary

Overview

The T16xxxH series is a family of high-power thyristors (Silicon Controlled Rectifiers) designed for demanding industrial and power electronics applications. These devices are optimized for high voltage switching with excellent thermal performance thanks to their TO-220 package. The series offers multiple voltage ratings from 400V to 800V, making it suitable for a wide range of AC power control applications.

As a member of the phase-control thyristor family, the T16 provides reliable switching capabilities for half-wave or full-wave AC power control. The robust construction ensures stable operation even under high surge current conditions.

Design Considerations

When designing with the T16 series, consider the following:

Thermal Management

Proper heat sinking is critical for reliable operation at full current ratings. Use thermal compound between the device and heat sink to minimize thermal resistance.

Gate Drive Requirements

Ensure adequate gate drive current (typically 2-3 times I_GT) for reliable triggering, especially at low temperatures. A gate resistor (10Ω to 100Ω) is recommended to limit gate current.
