The 1SMC170CA is a surface mount transient voltage suppressor (TVS) diode manufactured by Central Semiconductor Corp. It is designed to protect sensitive electronic components from voltage transients induced by lightning, electrostatic discharge (ESD), inductive switching, and other transient voltage events. The diode is packaged in a small SMC (DO-214AB) package, making it suitable for space-constrained applications where higher power dissipation is needed and where bidirectional protection is required.

Additional Details

The 1SMC170CA TVS diode is designed to be connected in parallel with the circuit to be protected. During normal operation, the diode presents a high impedance to the circuit. When a transient voltage exceeds the diode's stand-off voltage, the diode rapidly becomes conductive, clamping the voltage to a safe level and diverting the surge current away from the protected components. The 1SMC170CA is a bidirectional device, meaning it is designed to protect against both positive and negative voltage transients. The diode is rated for a peak pulse power of 1500W with a 10/1000µs waveform. Operating and Storage Temperature: -65°C to +150°C
