Component Specifications

Definition
Leads and terminals are conductive components designed to establish electrical connections between clamping devices (such as TVS diodes) and circuit boards or wiring systems. They serve as interface points that ensure reliable electrical contact, mechanical stability, and proper current flow while withstanding environmental stresses and thermal cycling.
Working Principle
Leads/terminals function by providing a conductive pathway between the clamping device's internal semiconductor structure and external circuits. They utilize metallic conductors with specific geometries to ensure low-resistance connections, proper heat dissipation, and mechanical retention within the clamping assembly. The design ensures electrical continuity while maintaining isolation between different potential points.
Materials
Copper alloys (C11000, C19400), phosphor bronze (C51000), brass (C26000), or nickel-plated steel; often with tin, silver, or gold plating for improved conductivity and corrosion resistance.

Frequently Asked Questions

What is the difference between leads and terminals in clamping devices?

Leads refer to the conductive wires or pins extending from the clamping device body, while terminals are the connection points where these leads interface with external circuits. Leads are integral to the device, while terminals may be separate components or part of the mounting system.

How do material choices affect lead/terminal performance?

Material selection impacts conductivity, corrosion resistance, mechanical strength, and thermal performance. Copper alloys offer excellent conductivity, while plating with tin/silver/gold enhances surface properties. Material choices must balance electrical requirements with environmental conditions and cost considerations.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
