SMA6J28CA-TR Transient Voltage Suppressor by STMicroelectronics

The SMA6J28CA-TR from STMicroelectronics is a robust Transient Voltage Suppressor (TVS) designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This component is a part of the SMA6J Series, which is well-regarded for its high surge capability and fast response time to transient over-voltages.

Encased in a compact SMA (DO-214AC) package, the SMA6J28CA-TR is optimized for space-constrained applications while providing a high level of protection for voltage-sensitive circuits. Its bidirectional clamping feature makes it suitable for AC applications, where the polarity of the transient could be positive or negative.

Key Features:

• Stand-off Voltage: The device has a stand-off voltage of 28V, making it suitable for a range of applications that require this level of voltage protection.
• Peak Pulse Power: It can handle a peak pulse power dissipation of 600 Watts (10/1000 µs surge), ensuring reliable protection against high energy transients.
• Clamping Voltage: With a low clamping voltage, the SMA6J28CA-TR effectively limits the voltage spikes and prevents damage to the protected component.
• Fast Response Time: The device reacts in picoseconds to over-voltage events, providing immediate protection to downstream components.
• Operating Temperature Range: The TVS can operate over a wide temperature range from -55°C to +150°C, suitable for various industrial and consumer applications.
• Low Leakage Current: It features low leakage current, which helps to reduce power loss and improve the overall efficiency of the system it protects.
• RoHS Compliant: The product is RoHS compliant, meaning it meets the European Union's restrictions on the use of certain hazardous substances in electrical and electronic equipment.

Applications:

The SMA6J28CA-TR is ideal for protecting voltage-sensitive components in a variety of applications, including:

• Power Supply Units (PSUs)
• Automotive electronics
