Bourns CDSOT23-SM712 is a bidirectional Transient Voltage Suppressor diode with 400W peak power dissipation and 20uA reverse current. Ideal for surge protection in applications requiring a max clamping voltage of 14V, such as IEC-61000-4-2 compliant systems. Operates b/w -55°C to 150°C with matte tin finish and Gull Wing terminals.
2N2222A by Texas Instruments is a small signal NPN bipolar junction transistor (BJT) with a max collector-emitter voltage of 40V and a max collector current of 0.8A. It is commonly used for switching applications due to its fast turn on/off times (35ns/285ns) and high transition frequency (300MHz).
