Vishay SMBJ3V3 Unidirectional TVS Diode 3.3V DO-214AA (SMB)
Vishay SMBJ3V3 unidirectional TVS diode, 3.3V standoff, 600W peak pulse power, DO-214AA (SMB) surface-mount package.
Vishay SMBJ3V3 Unidirectional TVS Diode is a surface-mount Transient Voltage Suppressor with a 3.3V reverse standoff voltage and 600W peak pulse power dissipation, housed in a DO-214AA (SMB) package.
Overview
The SMBJ3V3 is a TRANSZORB surface-mount TVS diode designed to protect sensitive electronic components from transient voltage spikes. Its unidirectional design provides clamping capability with a fast response time, and it has a maximum clamping voltage of 7.3V.
Key Features
- Unidirectional polarity with a colour band marking the cathode end
- Peak pulse power dissipation of 600W
- Peak forward surge current of 60A
- Maximum reverse leakage current of 200μA at 3.3V
- Typical junction capacitance of 5200pF at 0V/1MHz
- Matte tin-plated lead terminals
- UL94V-0 flame-rated moulding compound
Applications
This TVS diode is suited to power management systems and lighting circuits where voltage transients are a concern. Its surface-mount design and compact DO-214AA (SMB) package suit modern, space-constrained PCB layouts, providing protection without occupying significant board space.
Installation
The colour band denotes the cathode end and should be observed for correct polarity identification during installation. The device has a power dissipation of 5W on an infinite heatsink.
Choose the Vishay SMBJ3V3 when a 3.3V unidirectional TVS diode in a compact DO-214AA (SMB) surface-mount package is required to help protect electronic assemblies from voltage transients.
