P6KE36CA

Updated: 2026-07-21

Overview

The P6KE36CA is a bidirectional transient voltage suppressor (TVS) diode widely used for protecting sensitive electronic components from voltage spikes and surges. It is part of the P6KE series, known for its reliability and performance in demanding environments. This diode operates by clamping transient voltages to a safe level, diverting excess current away from protected circuits. Its bidirectional design allows it to handle both positive and negative voltage transients, making it versatile for various applications.

Structure and Working Principle

The P6KE36CA consists of a silicon avalanche diode structure housed in a DO-15 package. When the voltage across the diode exceeds its breakdown voltage (36V), it conducts heavily, shunting the excess energy to ground. This rapid response (typically in picoseconds) ensures minimal exposure of downstream components to harmful transients. The bidirectional nature means it can protect against both positive and negative surges, unlike unidirectional TVS diodes.

Key Features

The P6KE36CA offers a peak pulse power dissipation of 600W, making it suitable for high-energy transient events. Its low clamping voltage ensures minimal stress on protected components. Other notable features include its fast response time, low leakage current, and robust construction. These characteristics make it a preferred choice for industrial, automotive, and telecommunications applications where reliability is critical.

Application Areas

The P6KE36CA is commonly used in power supplies, communication equipment, and automotive electronics to protect against lightning strikes, electrostatic discharge (ESD), and other transient events. In industrial settings, it safeguards control systems and sensors. In consumer electronics, it prevents damage from power surges. Its versatility and reliability make it a staple in circuit protection design.

Maintenance and Precautions

B2B Procurement Guide

When procuring P6KE36CA diodes, consider factors such as lead time, minimum order quantities, and supplier reliability. Bulk purchases often attract discounts, making them cost-effective for large-scale projects. Verify the authenticity of the components to avoid counterfeit products. Reputable suppliers typically provide datasheets and compliance certificates. For reference, prices range from $0.50 to $2.00 per unit, depending on quantity and supplier.
