When a transistor is in operation it experiences electric and thermal loads. The life of a transistor will be short if such loads exceed the maximum tolerances which may break the transistor in a worst case scenario. To avoid this, it is highly recommended to check if there are any issues with the driving the transistor during the design stage.

3) what is the working voltage? 4) is the transistor used as amplifier or as a switch? You'll need to apply 12V to the base of the PNP transistor to switch off (VEB = 0). Leaving PNP's behind, looking at the NPN's that you have availabe, only the BC547B (Ic = 100mA) couldn't handle the 480mA current that your siren needs. From the remaining 3 transistors, I'd choose the one that can handle the most current, just to be on the safe side.

Even if the spike is a millisecond or less! Choose a transistor of the same polarity: The first major selection criterion is whether the transistor is PNP or NPN. Select a replacement transistor of the same material: Most transistors are either silicon or germanium. As bias voltages and other features are different it is necessary to select a replacement transistor with the same material.

Caution GaAs Products This product uses gallium arsenide (GaAs).

If the max Ic value is exceeded, the transistor will probably "burn out". There are thousands of different types of transistors available, and each transistor has different parameters. Transistors are more complicated than resistors and capacitors because you can choose a resistor or capacitor according to required resistance or capacitance value but while choosing a transistor, you have to look for many transistor parameters.

When choosing a transistor it is important to make sure that the gain is high enough for the required use and that the maximum current which it can handle is sufficient to drive the output device. e.g. BFY 51 gain > 40 , max Ic = 1 amp. If the max Ic value is exceeded, the transistor will probably "burn out".

Transistors are small, versatile semiconductor devices designed to switch or amplify electronic signals and power. Almost all electronic devices today contain one or more transistors. Some transistors are individually packaged, but many more are embedded in integrated circuits.
