Additional Details

The 1SMC22CA features a stand-off voltage of 22V, suitable for protecting circuits operating at or around this voltage level. The 'CA' suffix indicates that it's a bidirectional device, offering protection against both positive and negative voltage transients. It comes in a surface-mount SMC/DO-214AB package. With its fast response time and high surge handling capability, the 1SMC22CA effectively clamps transient voltages to safe levels, preventing damage to downstream components. The operating temperature range is typically -55°C to +150°C.
