Vishay 1-Element Uni-Directional Transient Voltage Suppressor 600W 2-Pin DO-214AA SMBJ70A-E3/52

Vishay SMBJ70A-E3/52 is a single-element uni-directional transient voltage suppressor designed for protection of sensitive electronic circuits against voltage transients. This device offers a peak pulse power dissipation of 600 W using a 10/1000 μs waveform with a very low duty cycle of 0.01%, making it suitable for transient voltage protection applications in consumer, industrial, computer, and telecommunications equipment.

Featuring a compact surface mount DO-214AA (SMB) package with two pins, the suppressor is ideal for automated PCB assembly processes. The glass passivated chip junction technology ensures stable performance and longevity under operating conditions ranging from -55°C to 150°C.

The device's electrical characteristics include a minimum breakdown voltage of 77.8 V, maximum reverse stand-off voltage of 70 V, clamping voltage of 113 V, and a peak pulse current of 5.3 A. It has a very low maximum reverse leakage current of only 1 μA, enhancing energy efficiency during normal operation. The transient voltage suppressor meets the AEC-Q101 automotive standard, enabling its deployment in automotive electronic systems requiring high reliability.

Dimensions of 4.57 mm length, 3.94 mm width, and 2.24 mm height allow for compact circuit layout, making this device well suited for space-constrained applications. The suppressor’s very fast response time and excellent clamping capability protect ICs, MOSFETs, and signal lines from transient voltage spikes induced by inductive loads, switching, or lightning surges.

Applications include semiconductor protection in consumer electronics, industrial controls, communication equipment, and automotive circuits. The SMBJ70A-E3/52 device is a reliable component for mitigating electromagnetic disturbances and enhancing system robustness.
