The Bourns SMCJ78CA is a bidirectional transient voltage suppressor diode designed to protect sensitive electronics from voltage transients induced by lightning, ESD, and other surge events. It features a reverse standoff voltage of 78V and a maximum clamping voltage of 126V at a peak pulse current of 11.9A (10/1000µs waveform). The device can handle 1500W of peak pulse power and has a fast response time of less than 5ps from 0V to minimum breakdown voltage.
This TVS diode is housed in a standard DO-214AB (SMC) surface mount package, suitable for automated pick-and-place assembly. It operates over a junction temperature range of -55°C to +150°C and has a maximum steady state power dissipation of 5W at 75°C lead temperature. The bidirectional configuration makes it ideal for protecting AC signal lines or data lines where polarity is not fixed.
The SMCJ78CA is RoHS compliant and recognized under UL file number E153537. It meets IEC 61000-4-2 ESD Level 4, IEC 61000-4-4 EFT, and IEC 61000-4-5 surge immunity standards, making it suitable for industrial, telecom, and consumer applications requiring robust transient protection.
