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

STMicroelectronics SMBJ33CA-TR is a high-performance 1-element bi-directional TVS diode engineered to safeguard electronic circuits from voltage transients and surges. With a peak pulse power dissipation of 600 W, this device provides superior protection against electrostatic discharge, lightning surges, and other transient voltage events. The surface-mount DO-214 package facilitates seamless integration into compact printed circuit boards commonly used in industrial and electronic assemblies.

Featuring a robust diode configuration with a minimum breakdown voltage of 36.7 V and a maximum reverse stand-off voltage of 33 V, the diode ensures reliable clamping during voltage spikes, effectively protecting sensitive components downstream. The clamping voltage of 69.7 V is optimized for efficient energy absorption without damage. A maximum peak pulse current of 57 A highlights its capability to withstand high surge currents.

The wide operating temperature range from -55°C to 150°C suits the diode for harsh environments including industrial automation, power supplies, and telecommunications electronic subsystems. The compact dimensions of 4.6 mm (length), 3.95 mm (width), and 2.45 mm (height) enable flexible design layouts in modern electronics.

This TVS diode exhibits a low maximum reverse leakage current of 200 nA to minimize power consumption during normal operation. It is ideal for transient voltage suppression in critical applications such as power management, signal line protection, and automotive electronics where reliable transient suppression is essential but automotive certification is not a requirement.
