STMicroelectronics SMBJ70CA-TR TVS Diode

The SMBJ70CA-TR from STMicroelectronics is a robust transient voltage suppressor (TVS) diode, designed to protect sensitive electronic equipment from voltage spikes and transients. This component is part of STMicroelectronics' SMBJ series, which is known for its reliability and performance in surge protection. The SMBJ70CA-TR is specifically engineered to safeguard circuits against transient overvoltage events such as electrostatic discharges (ESD), electrical fast transients (EFT), and effects of secondary lightning.

With its bidirectional clamping feature, the SMBJ70CA-TR is capable of providing protection for both positive and negative voltage transients. This makes it an ideal choice for applications where the polarity of the transient could be in either direction. The device has a standoff voltage of 70V, which defines the maximum voltage that can be applied while maintaining the diode in a non-conductive state under normal operating conditions.

The SMBJ70CA-TR can handle peak pulse power dissipation of 600W for a 10/1000μs waveform, ensuring that it can withstand high-energy transients without sustaining damage. Its fast response time is crucial for protecting sensitive circuit components from immediate and potentially harmful voltage spikes.

Constructed in a DO-214AA package, also known as an SMB package, the SMBJ70CA-TR is designed for surface-mount applications, making it suitable for use in compact and high-density circuit designs. Its operating temperature range of -55°C to +150°C allows for deployment in environments with varying temperature conditions.

Applications that can benefit from the SMBJ70CA-TR include consumer electronics, computer systems, industrial equipment, and communication devices, among others. Its compliance with IEC standards for ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and surge (IEC 61000-4-5) ensures that it meets the rigorous requirements for electronic system protection.

In summary, the SMBJ70CA-TR TVS diode from STMicroelectronics is a high-quality protective component that provides reliable and efficient overvoltage protection for a wide range of electronic applications.
