Product Description
Vishay SMAJ18A-E3/61 is a high-performance 1-element uni-directional TVS diode engineered for transient voltage suppression in sensitive electronic circuits. It delivers 400 W peak pulse power dissipation in a compact DO-214 surface mount package with 2 pins, ideal for efficient printed circuit board assembly.
This TVS diode features a minimum breakdown voltage of 20 V and a maximum reverse stand-off voltage of 18 V, with a clamping voltage of 29.2 V to effectively clamp voltage surges. It supports a peak pulse current of up to 13.7 A, providing robust protection against transient voltage events.
The device operates reliably across a broad temperature range from -55°C to +150°C, making it suitable for automotive and industrial environments complying with the AEC-Q101 standard. Its low maximum reverse leakage current of 1 μA ensures minimal power loss during normal operation.
Measuring just 4.5 mm in length, 2.79 mm in width, and 2.09 mm in height, this TVS diode fits compact applications without compromising performance. The TRANSZORB® series represents Vishay's commitment to high-quality transient voltage suppressors with proven reliability across electronic, automotive, industrial, and manufacturing uses.
