Q4010R5Triac 400V 10A 50,50,50 mA TO220	Discrete Semiconductor Products	2	Unknown	10 Amp bi-directional solid state switch series is designed for AC switching and phase control applications such as motor speed and temperature modulation controls, lighting controls, and static switching relays. Standard type devices normally operate in Quadrants I & III triggered from AC line.
Q4012Altnstr 400V 12A 50-50-50 mA TO220	Thyristors	5	Active	12Amp bi-directional solid state switch series is designed for AC switching and phase control applications such as motor speed and temperature modulation controls, lighting controls, and static switching relays. Alternistor type devices only operate in quadrants I, II, & III and are used in circuits requiring high dv/dt capability.

Q4015Triac 400V 15A 50-50-50 mA TO220 Iso	TRIACs	7	Active	Teccor brand Quadrac devices are triacs that include a diac trigger mounted inside the same package. This device, developed by Littelfuse, saves the user the expense and assembly time of buying a discrete diac and assembling in conjunction with a gated triac. Also, the alternistor Quadrac device (QxxxxLTH) eliminates the need for a snubber network. The Quadrac device is a bidirectional AC switch and is gate controlled for either polarity of main terminal voltage. Its primary purpose is for AC switching and phase control applications such as speed controls, temperature modulation controls, and lighting controls where noise immunity is required. Triac current capacities range from 4A to 15A with voltage ranges from 200V to 600V. Quadrac devices are available in the TO-220 package. The TO-220 package is electrically isolated to 2500V rms from the leads to mounting surface. 4000V rms is available on special order. This means that no external isolation is required, thus eliminating the need for separate insulators and insulator-mounting steps and saving dollars over "hot tab" devices. All Teccor triac and diac chips have glass-passivated junctions to ensure long-term device reliability and parameter stability. Variations of devices in this data sheet are available for custom design applications. Consult the factory for more information.
Q4015L5TPTriac 400V 15A 50-50-50 mA TO220 Iso	Discrete Semiconductor Products	1	Active	15 Amp and 16 Amp bi-directional solid state switch series is designed for AC switching and phase control applications such as motor speed and temperature modulation controls, lighting controls, and static switching relays.
