VISHAY SMBJ3V3 TVS Diode, Unidirectional, 3.3V, DO-214AA (SMB)
VISHAY SMBJ3V3 TVS diode for circuit protection. 3.3V standoff, 7.3V clamp, 600W pulse power. Surface mount, unidirectional.
The VISHAY SMBJ3V3-E3/52 is a high-performance TRANSZORB® surface-mount Transient Voltage Suppressor (TVS) designed for reliable circuit protection. Its unidirectional design offers excellent clamping capability and an exceptionally fast response time to transient voltage spikes, safeguarding sensitive electronic components from damage. The device features matte tin-plated lead terminals and is encased in a UL94V-0 flame-rated moulding compound for safety and durability. A colour band clearly denotes the cathode end for correct polarity identification during installation.
This diode is engineered for robust performance in demanding applications. It provides a high peak forward surge current handling of 60A and a substantial peak pulse power dissipation of 600W. With a low maximum reverse leakage current of 200μA at 3.3V, it ensures efficient operation with minimal power loss. Its typical junction capacitance is 5200pF, making it suitable for a wide range of circuit designs.
Key Applications
This TVS diode is an ideal solution for power management systems and lighting circuits where voltage transients are a concern. Its surface-mount design and compact DO-214AA (SMB) package make it perfect for modern, space-constrained PCB layouts, offering reliable protection without occupying significant board space. It is a critical component for enhancing the longevity and reliability of electronic assemblies.
