It switches AC loads without requiring an external RC snubber network. ## Snubberless means one less passive The Snubberless designation means this triac is rated for high commutation dV/dt without an external RC snubber. The trade-off is the higher gate trigger current (35 mA). The 35 mA hold current also means the load must draw at least that much to stay latched on.","metaTitle":"STMicroelectronics T435-600T Snubberless Triac","metaDescription":"STMicroelectronics T435-600T Snubberless Alternistor triac, 600 V off-state, 4 A RMS, 35 mA Igt.
