High-voltage, low-frequency n-p-n transistor 3dd5023 with a resistor between the base-emitter resistance of 50 ohms and a damping diode between the collector and the emitter.Such a transistor can be found in old kinescope televisions
The main characteristics of the transistor:
- Base-collector voltage 1500 V
Collector-emitter voltage 600V
Base-emitter voltage 6V
Direct collector current 6A, in pulse 12A
Base current 3A
Power dissipation 35W
The time of charge transfer through the tf base is 1 ms
When checking on the tester for the serviceability of such a transistor, the tester will show that the transistor is allegedly faulty.In fact, the transistor is working.If you ring the base-emitter of the transistor with a multimeter, the ringer will beep and show the resistance of the resistor 50 ohms, this will be normal.
