STMicroelectronics SMBJ85A-TR TVS Diode
The SMBJ85A-TR from STMicroelectronics is a robust transient voltage suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by system inductive load switching and lightning. This high-quality TVS diode is specifically crafted to safeguard voltage-sensitive components which can be affected by transient voltage spikes and surges, making it an ideal choice for a wide array of applications, including industrial, automotive, telecommunications, and consumer electronics.
Encased in a compact SMB (DO-214AA) surface-mount package, the SMBJ85A-TR is engineered to deliver excellent clamping performance with a stand-off voltage of 85V. This feature ensures that devices are shielded from transient events while maintaining a low clamping voltage during surge events. The peak pulse power dissipation of this diode is an impressive 600W (10/1000μs), providing a strong defense against high-energy transients.
The SMBJ85A-TR is characterized by its fast response time, typically in the picosecond range, which allows it to react swiftly to any overvoltage event, thereby ensuring the highest level of protection for sensitive circuits. Its low incremental surge resistance further enhances its ability to suppress transient voltages effectively.
With its bidirectional design, the SMBJ85A-TR is capable of protecting circuits in both directions, making it a versatile component for various circuit configurations. The device also meets the ISO 7637-2 pulse 5a and 5b standards and is compliant with the IEC 61000-4-2 and MIL-STD-883, Method 3015 standards, ensuring reliability in the most demanding environments.
STMicroelectronics has designed the SMBJ85A-TR with the environment in mind. It is RoHS compliant and free from hazardous substances, aligning with global efforts for environmentally safe electronic components. Whether you are designing power supplies, sensitive communication devices, or looking to enhance the durability of automotive electronics, the SMBJ85A-TR offers a top-tier solution for transient voltage protection.
