APTGT400A120D3G

Transistors - IGBTs - Modules

The APTGT400A120D3G is a module of insulated gate bipolar transistors (IGBTs) that packs two IGBTs and an ultrafast, soft recovery anti-parallel diode in a single package. This small part has a broad range of applications and can be used for anything from straight-forward lighting and motor control to more complicated circuit designs such as induction and synchronous motors, power electronic current source inverters, and resonant converters.

Application field

The APTGT400A120D3G is often used for induction or synchronous motors with ratings up to 1000W. It can also be used in converters such as current source inverters, line- or heater-current-controlled rectifiers, and inverters. Due to its small size and lightweight, the APTGT400A120D3G is ideal for applications such as motor control, electro-hydraulic control, frequency control, and motor starting.

Working principle

The APTGT400A120D3G module consists of two IGBTs and an ultrafast, soft recovery anti-parallel diode. The IGBTs are power transistors that control the current flow in a circuit. They are designed to be used with an alternating current and can switch on and off in less than one micro-second with no ringing or oscillation. When connected to a suitable gate driver, the IGBTs can be turned on and off rapidly, allowing for very efficient power control. The anti-parallel diode works to prevent current from flowing back through the circuit when the IGBTs are turned off, helping to reduce losses and increase system efficiency.
