The SMBJ45CA-E3/52 is a bidirectional TVS diode from Vishay Dale designed for transient overvoltage protection. It features a 45V reverse standoff voltage and a clamping voltage of 72.7V. The device is rated for 600W peak pulse power dissipation under a 10/1000μs waveform and can handle 100A peak forward surge current (8.3ms half sine wave). With a power dissipation of 5W on an infinite heatsink at 50°C ambient, it operates reliably across a temperature range of -55°C to 150°C.
This TVS diode is housed in a DO-214AA (SMB) surface mount package, suitable for automated assembly. It is commonly used to protect sensitive electronics from voltage transients in power supplies, I/O interfaces, and communication lines. The bidirectional configuration allows protection for both positive and negative transients.
Key specifications include 600W peak pulse power, 100A surge current, and a wide operating temperature range. The device is RoHS compliant and lead-free, meeting modern environmental standards.
