Product Overview
BTA216X-600B High-Power Insulated TRIAC, Unused New Old Stock
The BTA216X-600B is a high-power insulated TRIAC designed for AC switching and phase control. Rated for 600V and 16A, it provides dependable bidirectional control of resistive and inductive loads such as lamps, heaters, and motors.
This device type originated in the classic BTA-series specification, long recognized across the industry for its insulated mounting tab and rugged thermal design. Though the original design was published by STMicroelectronics, compatible equivalents have been produced by multiple semiconductor manufacturers following the same electrical and mechanical standard.
Product Condition
Unused, New Old Stock; clean and in excellent condition. Kept in original packaging with no signs of corrosion or degradation. Factory insulation intact and ready for installation.
Product Overview
The BTA216X-600B is built for high reliability in AC control circuits. Its insulated TO-220F case simplifies heat-sink mounting, while a low gate trigger current allows direct interface with microcontrollers or low-power control circuits.
