This way, the SCR acts as an efficient power controller. DC Gate Trigger Current-Max: 30.0 mA, DC Gate Trigger Voltage-Max: 1.5 V. Circuit Commutated Turn-off Time-Nom: 15.0 s. The 10K variable resistor and the 1uF capacitor act like an RC time delay, controlling how much of one AC half cycle is seen by the load. Motorola - 2N6507 - SCR, Silicon Controlled Rectifier. Shown here in the figure below is a simple dimming circuit that controls the brightness of a lamp. The BT-151 can be used as a rectifier to provide pulsed DC current to various appliances. SCRs in many ways behave like diodes with similar forward drops, hence the name ‘controlled rectifier’. They stay in conduction till the anode-cathode current drops below a certain value called the holding current. stay on once triggered, even if the gate signal is removed. Teccors SCR products are half-wave, silicon-controlled rectifiers that. SCRs are like transistors but have the ability to latch, i.e. The BT-151 is a medium power SCR used for power switching. Note: Complete Technical Details can be found in the BT151 SCR datasheet present at the end of this page.īT151 Equivalent SCRs: BT152, TYN208, 2N6508
