Présentation

Equivalent

The SM2T3V3A is a transient voltage suppressor (TVS) diode. Equivalent products include:
- SMAJ3.3A (Littelfuse)
- P6SMB3.3A (ON Semiconductor)
- 3.3SMCJxxA (Vishay/Bourns)
- SMBJ3.3A (STMicroelectronics)
These are bidirectional TVS diodes with similar voltage (3.3V) and power ratings. Verify specs (breakdown voltage, clamping voltage, power dissipation) for exact compatibility.

Features

The SM2T3V3A is a 3.3V bidirectional TVS diode designed for ESD protection in high-speed interfaces like USB, HDMI, and Ethernet. Key features:
- Voltage Rating: 3.3V working voltage.
- Bidirectional Protection: Guards against positive and negative transient voltages.
- Low Clamping Voltage: Effective surge suppression (IEC 61000-4-2 Level 4: ±8kV contact, ±15kV air).
- Ultra-Low Capacitance: Typically 0.5pF, ensuring minimal signal distortion for high-speed data lines.
- Compact Package: SOT-23 for space-constrained designs.
- Fast Response Time: Reacts in nanoseconds to transient spikes.
Ideal for protecting sensitive electronics in consumer, industrial, and automotive applications.

Pinout

The SM2T3V3A is a 3-pin TVS diode array designed for ESD protection in high-speed interfaces like USB, HDMI, and Ethernet.
Pin Functions:
1. Pin 1 (I/O1): Connects to the first signal line needing protection.
2. Pin 2 (GND): Ground reference for clamping transient voltages.
3. Pin 3 (I/O2): Connects to the second signal line needing protection.
Key Features:
- Bidirectional ESD protection (up to ±30kV, IEC 61000-4-2).
- Low clamping voltage (3.3V typical).
- Ultra-low capacitance (~0.5pF per line) for minimal signal distortion.
Applications: High-speed data lines (USB 2.0/3.0, HDMI, etc.).
