TVS–Diodes or Transient Voltage Suppressor Diodes (TVSD), are semiconductor components used to protect electrical equipment from short- duration electrical transients resulting from lightning strikes, induction of current from power lines, and other electrical spikes. The BZG04–43TR3 TVS is a simple, yet powerful device designed to provide effective protection to sensitive electronic components that may be damaged by high voltage transients.

The BZG04–43TR3 is a surface-mount SOD-444 type device with a built-in Avalanche Diode. The integrated diode has an avalanche breakdown voltage of 43V and a peak pulse power rating of 500W. The device is capable of withstanding high input voltages and is UL 1449 4th Edition listed, making it suitable for use in a wide range of applications.

The BZG04–43TR3 is designed to provide effective transient protection in areas exposed to destructive surges. The integrated diode allows for higher peak pulse power without sacrificing the clamping voltage. This device is ideal for protecting sensitive electronic components such as mobile phones, home appliances, computers and telecom equipment.

The BZG04–43TR3 works by instantly responding to a spike in voltage and dissipating the excess energy. The integrated diode limits the excess voltage to a safe level with minimal voltage drop. As the signal passes through the device, it is checked for critical values of voltage. If the signal exceeds the threshold voltage (Vt1), the integrated diode triggers. This action limits the excess voltage to a safe level and provides effective protection to the electronic components.

The BZG04–43TR3 is constructed using a patented design and comes in a small surface-mount package. The device features a low closure time, high surge current capability and low leakage current. The device also comes with an integrated heat sink for improved thermal performance, as well as low clamping voltage and fast response time.

Overall, the BZG04–43TR3 is an effective transient voltage suppressor designed to protect sensitive electronic components from high voltage spikes and transients. The device is equipped with a built-in avalanche diode, allowing it to withstand high input voltages while dissipating excess energy. The device is UL 1449 4th Edition listed, making it suitable for use in a wide range of applications.
