STMicroelectronics SMBJ170CA-TR TVS Diode

The SMBJ170CA-TR from STMicroelectronics is a robust transient voltage suppressor (TVS) diode, designed to provide high-quality surge and electrostatic discharge (ESD) protection in a compact package. This product is engineered to shield sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events.

Key Features

• Stand-Off Voltage: The device has a stand-off voltage of 170V, which is the maximum voltage that the diode can withstand without conducting in its reverse direction.
• Peak Pulse Power: It offers an impressive peak pulse power dissipation of 600W (10/1000μs), ensuring that it can handle significant surge events without damage.
• Clamping Voltage: With a clamping voltage of 275V, this TVS diode can effectively clamp transient overvoltages, preventing them from damaging the protected component.
• Bi-directional Protection: As a 'CA' type device, it provides bi-directional protection, making it suitable for AC applications or where the polarity of the transient could be either direction.
• Low Leakage Current: The SMBJ170CA-TR is characterized by its low leakage current, ensuring minimal power loss when the device is in the standby mode.
• Fast Response Time: The diode's response time is virtually instantaneous (<1ps), providing immediate protection against voltage spikes.
• Compact SMB Package: Housed in a Surface-Mounted Device (SMD) SMB package, it is suitable for high-density circuit board designs.

Applications

The SMBJ170CA-TR is ideal for a variety of applications where transient voltage protection is critical. These include:
