## Description
The Littelfuse SMBJ36CA is a bidirectional transient voltage suppressor (TVS) diode designed for the protection of sensitive electronic equipment against voltage transients induced by lightning and other high-energy surge events. Housed in a compact, low-profile DO-214AA (SMB) surface-mount package, this component offers a peak pulse power dissipation of 600W based on a 10/1000µs waveform. With a reverse standoff voltage of 36V and a maximum clamping voltage of 58.1V, it provides effective protection for I/O interfaces, VCC buses, and data communication lines in industrial, telecommunications, and consumer electronic applications.
This TVS diode features a minimum breakdown voltage of 40V and a maximum breakdown voltage of 44.2V, ensuring reliable triggering during overvoltage conditions. The device is engineered for high-temperature stability, with an operating temperature range spanning -65°C to 150°C. It is fully RoHS compliant, halogen-free, and meets MSL level 1 standards per J-STD-020, facilitating high-temperature reflow soldering up to 260°C for 30 seconds. The SMBJ36CA is UL Recognized to ANSI/UL 497B, confirming its suitability for data communications and fire-alarm circuit protection where robust, fast-response transient suppression is required.
