Overview

Description

The SMBJ3V3-E3/52 is a surface-mount transient voltage suppressor (TVS) diode designed to protect sensitive electronics from voltage spikes and transients. Key features:
- Voltage Rating: 3.3V (standoff)
- Peak Pulse Power: 600W (8/20µs waveform)
- Breakdown Voltage: ~3.67V (min)
- Low Clamping Voltage: Fast response to surges
- Package: SMB (DO-214AA)
Commonly used in power supplies, communication ports, and automotive circuits, it safeguards against ESD, lightning, and inductive switching events. The E3/52 suffix indicates specific packaging (tape & reel) and RoHS compliance.
For detailed specs, refer to the manufacturer’s datasheet.

Pinout

The SMBJ3V3-E3/52 is a 3.3V bidirectional TVS diode in an SMB (DO-214AA) package.
- Pin Count: 2 pins (anode and cathode).
- Function: Protects sensitive electronics from transient voltage spikes (ESD, surges) by clamping excess voltage to a safe level (3.3V). It is bidirectional, meaning it safeguards against both positive and negative voltage transients.
Key Features:
- Standoff Voltage: 3.3V
- Peak Pulse Power: 600W (8/20µs waveform)
- Low clamping voltage for effective protection.
Commonly used in power lines, data interfaces, and communication ports.

Package

The SMBJ3V3-E3/52 is a surface-mount TVS diode in an SMB (DO-214AA) package. It provides transient voltage suppression for protection against surges, with a standoff voltage of 3.3V. The package is compact, suitable for high-speed circuit protection, and compliant with industry standards.
