The SMAJ78CA is a bidirectional TVS diode from Littelfuse Inc., part of the SMAJ series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
Key electrical specifications include a reverse standoff voltage of 78V, a maximum clamping voltage of 126V, and a peak pulse current rating of 3.2A under a 10/1000µs waveform. The device can handle 400W of peak pulse power under the same test condition. It operates over a junction temperature range of -65°C to 150°C.
The SMAJ78CA is surface-mountable and comes in a DO-214AC (SMA) package. It is RoHS3 compliant, halogen free, and lead free, with an MSL level of 1 (unlimited). This TVS diode is suitable for general-purpose applications such as protecting I/O interfaces, VCC buses, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
