Littelfuse 1-Element Bi-Directional TVS Diode 600 W Surface Mount DO-214 SMBJ33CA

Littelfuse SMBJ33CA is a 1-element, bi-directional transient voltage suppression (TVS) diode designed for surface mount applications, packaged in the DO-214 format. It provides a peak pulse power dissipation of 600 W, making it ideal to protect sensitive electronic circuits from transient voltage spikes and surges typically caused by inductive load switching or lightning strikes.

The diode features a minimum breakdown voltage (Vbr) of 36.7 V and a maximum reverse stand-off voltage (Vwm) of 33 V, ensuring stable operation within defined voltage limits. Its clamping voltage (Vc) of 53.3 V offers effective voltage spike containment while maintaining low leakage currents under normal conditions, rated at a maximum of 1 μA.

Its surface mount package (DO-214) with compact dimensions of 4.57 mm length, 3.94 mm width, and 2.237 mm height allows for space-efficient PCB layouts, suitable for modern electronics manufacturing processes. The device operates reliably over a wide temperature range from -65°C to 150°C, supporting use in demanding industrial, automotive, and commercial electronics environments.

The SMBJ33CA TVS diode includes electrostatic discharge (ESD) protection capability with a test current of 1 mA and a maximum peak pulse current of 11.3 A, further enhancing circuit robustness. This diode is part of Littelfuse’s SMBJ series, renowned for quality and durability in transient suppression applications.
