4. Suggestions for Engineering Design

1. Do not exceed the device’s maximum rated voltage, current and power dissipation in practical circuits to prevent permanent device damage.
2. SOT-223 package dissipates heat through PCB copper foil. Sufficient copper area shall be reserved in layout to keep junction temperature within safe limits.
3. Collector cut-off current rises significantly with ambient temperature increase. Evaluate leakage-current impact on whole circuits under high-temperature working conditions.
4. BCP51-BCP53 series PNP transistors can be selected as complementary-pair devices for push-pull circuit design.
5. Select proper DC-gain grade according to practical operating current for amplifier-circuit design to secure stable operating point.
