Additional Details

The BCR3KM-14LA is typically used in applications where precise control of AC power is required. Its high surge current capability makes it suitable for motor control and lighting applications. When using this SCR, it's essential to consider the gate trigger current, holding current, and latching current to ensure proper operation. Heat sinking may be required depending on the operating conditions to maintain the device within its specified temperature range.

Because it is an end-of-life product, designers should investigate available replacements from Renesas or other manufacturers.
