40RIA120, SCR Thyristor, TO-65 Package

The 40RIA120 is a silicon-controlled rectifier (SCR) thyristor designed for high-power control applications such as motor speed control, power regulators, and industrial power conversion. With a 1200V blocking voltage and 40A current rating, it ensures reliable operation in demanding environments. The TO-65 package improves heat dissipation, making it ideal for continuous high-power operation.

• High Voltage Capability – Rated for 1200V repetitive peak off-state voltage (VDRM).
• High Current Handling – Supports 40A average on-state current (IT(AV)).
• Surge Protection – Can withstand 500A surge current for high transient loads.
• Low On-State Voltage Drop – Enhances efficiency with a 1.55V forward voltage at 40A.
• Fast Switching Capability – Ideal for phase control applications.
• Robust Metal Case (TO-65) – Provides excellent thermal performance and durability.
