SMBJ33CA Description

Short technical summary and product information.

The SMBJ33CA is a bidirectional Zener transient voltage suppression diode manufactured by Taiwan Semiconductor. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and other surge events.

 

Key electrical parameters include a reverse standoff voltage of 33 V, a maximum clamping voltage of 53.3 V at a peak pulse current of 11.3 A, and a peak pulse power dissipation of 600 W. The device features a fast response time of less than 5 picoseconds from 0 V to minimum breakdown voltage, ensuring rapid clamping of transient overvoltages.

 

This TVS diode is housed in a standard DO-214AA (SMB) surface mount package, suitable for automated pick-and-place assembly. The operating temperature range spans -55 °C to 150 °C, making it suitable for both commercial and industrial environments.

 

Applications include general purpose circuit protection, power supply protection, and protection of I/O interfaces against IEC 61000-4-2 ESD (Level 4), IEC 61000-4-4 EFT, and IEC 61000-4-5 surge conditions.
