Notes
1. Provided the IE rating is not exceeded.
2. During switching on, the device can withstand the discharge of a capacitor of a maximum value of 500 pF. This
capacitor is charged when the transistor is in cut-off condition, with a collector supply voltage of 160 V and a series
resistance of 100 kΩ.

Explanation of symbols
For application of the BRY39 as a programmable
unijunction transistor, only the anode gate is used. To
simplify the symbols, the term gate instead of anode gate
will be used (see Fig.2).
