5 FAQs of 100mA Bi-directional Controlled Thyristors (BCT)

What is a 100mA Bi-directional Controlled Thyristor (BCT)? A 100mA BCT is a semiconductor device designed to control alternating current (AC) power in both directions. It can handle currents up to 100mA and is triggered by a gate signal, enabling precise switching for low-power applications. Unlike standard thyristors, it conducts current bidirectionally, making it ideal for AC circuits without additional components.

How does a 100mA BCT work? The BCT consists of two thyristors connected in inverse parallel, allowing current flow in both directions. When a gate pulse is applied during either the positive or negative half-cycle of AC voltage, the device turns on and conducts until the current drops below its holding threshold (100mA). This enables controlled switching for AC loads.

What are typical applications of 100mA BCTs? These devices are used in low-power AC control systems, such as dimmer switches, small motor speed controllers, and temperature regulators in home appliances. They are also common in lighting systems, HVAC controls, and industrial automation equipment requiring bidirectional switching with precise current management.

What advantages do 100mA BCTs offer over other thyristors? BCTs eliminate the need for separate anti-parallel thyristors in AC circuits, simplifying design. Their low holding current (100mA) ensures energy efficiency in low-power applications. They provide reliable bidirectional control with a single gate trigger, reducing component count and cost compared to traditional setups.

How do I select the right 100mA BCT for my application? Consider voltage ratings (peak and RMS), gate trigger current requirements, thermal management needs, and switching speed. Ensure the device’s voltage rating exceeds your circuit’s maximum AC voltage. Match the gate trigger current to your control circuit’s capability, and verify thermal limits align with operating conditions to prevent overheating.
