STMicroelectronics SMA6J170A-TR Product Overview

The SMA6J170A-TR from STMicroelectronics is a robust and high-performance transient voltage suppression (TVS) diode, designed to protect sensitive electronic equipment from voltage transients induced by system-level events such as load dump, lightning, and electrostatic discharge (ESD). This TVS diode is a go-to solution for safeguarding critical applications across a wide range of industries, including automotive, industrial control, telecommunications, and consumer electronics.

Key Features

• Stand-off Voltage: The device features a stand-off voltage of 170V, which allows it to tolerate high transient overvoltages without going into breakdown.
• High Surge Capability: With a peak pulse power dissipation of 600W (10/1000µs), the SMA6J170A-TR is capable of handling significant surge events, ensuring reliable protection for your electronics.
• Low Clamping Voltage: Once the transient voltage exceeds the stand-off voltage, the TVS diode clamps the voltage to a safe level, thereby protecting the downstream circuitry from high voltage spikes.
• Fast Response Time: The device responds to overvoltage events in picoseconds, providing immediate protection against transient voltage spikes.
• Unidirectional Protection: This TVS diode offers unidirectional protection, making it suitable for DC voltage applications where the polarity is fixed.
• Compact Package: Housed in a surface-mount SMA package, the SMA6J170A-TR is designed for efficient PCB layout and is compatible with high-volume assembly processes.
• Automotive Qualification: The device is AEC-Q101 qualified, ensuring reliability and performance under the stringent conditions typical of automotive environments.
