The SMDA15C-4/TR7 is a robust transient voltage suppressor (TVS) diode array from Microchip Technology, designed to protect sensitive electronic equipment from voltage transients induced by system-level electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. This high-performance device is particularly suitable for multi-line applications where board space is at a premium and strong protective measures are essential.

Key Features

• Transient Protection: The SMDA15C-4/TR7 is capable of protecting against transients up to 400 Watts (@10/1000μs) per line (1-4), providing robust defense against surges.
• Low Clamping Voltage: This TVS diode array has a low clamping voltage, which ensures that the protected components are exposed to minimal stress during transient conditions.
• ESD Protection: It offers excellent ESD protection for electronic equipment, meeting IEC 61000-4-2 (ESD) standards, with ±30kV (air), ±30kV (contact) discharge capability.
• Multi-Line Protection: The device features four lines of protection in a common anode configuration, making it efficient for protecting multiple lines using a single component.
• Low Leakage Current: Minimizing power loss, it has a low leakage current of less than 1μA, ensuring energy efficiency in standby mode.
• Package: The SMDA15C-4/TR7 is offered in a SO-8 package, which is ideal for saving space on densely packed PCBs.
