This is a document about Vishay Telefunken's BUD620 high voltage switching transistor. The transistor features simple switch-off function, high-speed technology, planar passivation, 100 kHz switching rate, and so on.
The document describes the BUD620 as a Simple-Switch-Off Transistor (SWOT) featuring High Speed technology. Key characteristics include a 100 kHz switching rate, very low switching losses, and very low dynamic saturation voltage.
It is designed for applications such as electronic lamp ballast circuits and switch-mode power supplies. The device operates with a collector-emitter breakdown voltage of 400 V and supports a total power dissipation of up to 25 W at a case temperature of 60°C. This manual is written in Chinese.
| Collector-emitter voltage (VCEO) | 400 V |
|---|---|
| Total power dissipation (Ptot) | 25 W |
| Collector current (IC) | 4 A |
| Switching rate | 100 kHz |
The absolute maximum collector-emitter voltage (VCEO) is rated at 400 V.
This transistor is intended for use in electronic lamp ballast circuits and switch-mode power supplies.
To order the SMD package, add "-SMD" to the type number (e.g., BUD620 -SMD).
