Detailed Pin Configuration

The 1.5KE18C diode has a standard axial lead configuration with two leads emerging from the cylindrical body of the DO-201 package. The anode is connected to the positive lead, while the cathode is connected to the negative lead.

Functional Features

The 1.5KE18C diode provides robust protection against voltage transients by quickly diverting excess current away from sensitive components. Its fast response time ensures that the protected circuit is shielded from damaging voltage spikes.

Advantages and Disadvantages

Advantages

• High surge capability
• Low clamping voltage
• Fast response time

Disadvantages

• Relatively large package size compared to surface-mount alternatives
• Limited availability in small quantity packaging

Working Principles

When a voltage transient occurs, the 1.5KE18C diode rapidly conducts excess current, effectively clamping the voltage across the protected circuit. This action prevents the voltage from reaching levels that could damage sensitive components.

Application Field Plans

The 1.5KE18C diode is commonly used in applications such as power supplies, telecommunications equipment, automotive electronics, and industrial control systems. Its ability to handle high surge currents makes it suitable for protecting a wide range of electronic devices from voltage spikes.

Alternative Models

Some alternative models to the 1.5KE18C diode include: - 1.5KE15C - 1.5KE16C - 1.5KE20C - 1.5KE22C

These diodes offer similar transient voltage suppression capabilities and can be used as substitutes depending on specific application requirements.
