The SMBJ33A from Bourns is a unidirectional Transient Voltage Suppressor (TVS) diode designed for general purpose circuit protection. It features a standoff voltage of 33 V, a typical clamping voltage of 53.3 V at a peak pulse current of 11.3 A, and a peak pulse power dissipation of 600 W (10/1000 µs waveform). The device offers an extremely fast response time of less than 1 picosecond, making it suitable for protecting sensitive electronics from ESD, EFT, and surge events per IEC 61000-4-2, IEC 61000-4-4, and IEC 61000-4-5 standards.
The SMBJ33A is housed in a surface mount DO-214AA (SMB) package, which is compatible with standard pick-and-place assembly processes. It operates over a junction temperature range of -55°C to 150°C and has a steady state power dissipation of 5 W at 75°C lead temperature. The device is RoHS3 compliant and REACH unaffected, though MSL is rated as Level 1 (unlimited) with low confidence.
This TVS diode is not intended for power line protection but is well-suited for data lines, I/O interfaces, and other low-voltage signal lines requiring robust transient protection. Its compact SMB package and high surge capability make it a reliable choice for portable communications, computing, and industrial equipment.
