The Vishay SMAJ12AHE3/61 is a high-performance Transient Voltage Suppression (TVS) diode designed to protect sensitive electronic equipment from voltage spikes and transient surges. With a working standoff voltage (V<sub>WM</sub>) of 12V and a peak pulse surge current (I<sub>PP</sub>) of 20.1A, this diode effectively clamps voltages to a safe level of 19.9V. Encased in a DO-214AC (SMA) surface-mount package, it is ideal for space-constrained applications. This TVS diode offers fast response time and low clamping voltage, ensuring reliable protection for automotive, industrial, and consumer electronics. Vishay’s robust design ensures long-term stability and performance.
