Ultrasonic Welding Generator Transistor Selection & DMM Testing | BUX98A, 2SC5047

In this video, we explain how to select and test ultrasonic welding generator transistors using a digital multimeter (DMM). These transistors are used in Villard amplifier circuits and high-frequency ultrasonic welding generators, especially in old-model industrial machines.

We cover real-world testing methods, correct voltage and current ratings, and common mistakes technicians make when replacing high-voltage power transistors. This guide is based on practical repair experience, not blind datasheet theory.

🔧 Transistors explained in this video:

2SC5047 – 800V, 25A (first choice for ultrasonic generators)

2SC3998 – high-frequency power transistor

2SC3997 – commonly used in Villard amplifiers

BUV48B – medium-voltage ultrasonic driver transistor

BUV84B – high-speed switching transistor

BUX98A – old-model ultrasonic welding generator transistor
