Product Overview: SMAJ70CA-TR by STMicroelectronics

The SMAJ70CA-TR is a high-quality transient voltage suppression (TVS) diode designed and manufactured by STMicroelectronics, a leader in the semiconductor industry. This robust component is specifically engineered to protect sensitive electronic equipment from voltage spikes and transients induced by lightning and other transient voltage events.

Key Features

• Bi-directional Protection: The SMAJ70CA-TR offers bi-directional clamping, making it suitable for AC applications or where the polarity is reversible, providing versatile protection for various circuits.
• Stand-off Voltage: With a stand-off voltage of 70V, this device is capable of withstanding overvoltages without transitioning to its low-impedance state, ensuring the protection of downstream components.
• Peak Pulse Power: It can handle a peak pulse power of 400W (10/1000μs), allowing it to absorb significant energy associated with transient voltage spikes.
• Fast Response Time: The TVS diode provides a fast response time to transient events, typically in the picosecond range, ensuring immediate protection against overvoltage conditions.
• Low Leakage Current: The low leakage current of the SMAJ70CA-TR minimizes power loss when the diode is in its stand-by state, thus conserving energy in the protected system.
• Package: Housed in a compact SMA (DO-214AC) package, it is suitable for high-density circuit board designs, saving valuable board space.
