III. PNP Transistor Selection
The D365A requires an external pnp transistor to complete the high voltage 3P circuitry. Ideally, this transistor should
have a minimum collector-emitter breakdown voltage higher than the required peak voltage output of the EL driver. It
should also have a high DC current gain (>50) and fast switching characteristics.
Durel typically recommends the MMBTA56 surface mount amplifier transistor for general purpose because it is a
standard device part number supplied by several large manufacturers. The MMBTA56 has a breakdown voltage that
is normally above 100V although it has a minimum rating of 80V only. The counterpart internal npn transistor in the D365
has a minimum 100V breakdown, with typical breakdown value above 120V. Under most nominal design considerations
using the D365, the MMBTA56 is an appropriate selection. Nevertheless, caution is advised to limit designs well within
the maximum output voltage ratings of all devices to avoid failure of the IC or any required external components.
D365 Design Ideas
I. Alternate Lamp Connection
In some applications it may be more convenient to connect the EL lamp to the supply voltage rather than ground. This
connection (shown below) provides design flexibility and does not degrade EL driver performance. This configuration
may also be used to minimize any positive DC bias on the lamp.
