SMA6J85CA-TR

Product Overview

The SMA6J85CA-TR belongs to the category of TVS (Transient Voltage Suppressor) diodes. These diodes are used to protect sensitive electronics from voltage spikes and transient events. The SMA6J85CA-TR is characterized by its high surge capability, low clamping voltage, and fast response time. It is typically packaged in a DO-214AC (SMA) package and is available in tape and reel packaging with a quantity of 3000 units per reel.

Specifications

• Peak Pulse Power: 600W
• Breakdown Voltage: 85V
• Clamping Voltage: 137V
• Operating Temperature Range: -55°C to +150°C
• Package Type: DO-214AC (SMA)

Detailed Pin Configuration

The SMA6J85CA-TR has two pins, with the anode connected to pin 1 and the cathode connected to pin 2.

Functional Features

The primary function of the SMA6J85CA-TR is to provide overvoltage protection for electronic circuits. When a transient event occurs, the diode rapidly conducts, diverting the excess current away from the protected circuit, thus limiting the voltage across it.

Advantages and Disadvantages

Advantages: - High surge capability - Low clamping voltage - Fast response time

Disadvantages: - Limited breakdown voltage compared to higher voltage-rated TVS diodes - Sensitive to reverse bias conditions

Working Principles

When the voltage across the SMA6J85CA-TR exceeds its breakdown voltage, the diode begins to conduct, providing a low-impedance path for the excess current. This effectively clamps the voltage across the protected circuit to a safe level, preventing damage from transient events.

Detailed Application Field Plans

The SMA6J85CA-TR is commonly used in various electronic systems, including power supplies, communication equipment, automotive electronics, and industrial controls. Its ability to handle high surge currents makes it suitable for applications where protection against voltage transients is critical.

Detailed and Complete Alternative Models

Some alternative models to the SMA6J85CA-TR include the SMA6J series from different manufacturers such as Vishay, ON Semiconductor, and Littelfuse. These alternatives offer similar transient voltage suppression capabilities but may vary in terms of breakdown voltage, clamping voltage, and package options.
