TVS - Diodes

TVS Diodes Robust Circuit Protection for Transient Voltage Suppression

Definition:
TVS Diodes (Transient Voltage Suppression Diodes) are specialized semiconductor devices designed to protect sensitive electronics from voltage spikes and transient events, such as ESD (electrostatic discharge), lightning surges, or inductive load switching. They act as fast-acting voltage clamps, diverting excess current away from critical components to ensure system reliability.

Product Types:
This category includes:
- Unidirectional TVS Diodes: Clamp positive voltage transients, ideal for DC circuits.
- Bidirectional TVS Diodes: Protect against both positive and negative surges, suited for AC lines or bidirectional signals.
- High-Power TVS Arrays: Multi-channel solutions for robust protection in industrial or automotive applications.
- Low-Capacitance TVS: Optimized for high-speed data lines (e.g., USB, HDMI) to minimize signal distortion.

Purchasing Guidance:
1. Voltage Rating: Select a standoff voltage slightly above the operating voltage of your circuit.
2. Peak Pulse Power: Ensure the diode can handle the expected surge energy (e.g., 600W, 1500W).
3. Response Time: Prioritize ultra-fast models (<1ns) for ESD-sensitive devices.
4. Package Type: Choose SMD (e.g., SOD-323) for compact PCBs or through-hole for high-power needs.

TVS Diodes are a cost-effective safeguard against catastrophic failures invest in the right specification to balance protection and performance.
