Vishay Uni-Directional TVS Diode 600 W, 2-Pin DO-214 Surface Mount SMBJ85A-E3/52

The Vishay SMBJ85A-E3/52 is a Uni-Directional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic components from voltage transients such as those caused by inductive load switching and lightning. It is a single-element diode capable of dissipating peak pulse power of 600 W using a 10/1000 μs waveform. The diode is housed in a compact surface mount DO-214 package with two pins, making it compatible with automated PCB manufacturing processes.

This device features a minimum breakdown voltage (Vbr) of 94.4 V and a maximum reverse stand-off voltage (Vwm) of 85 V, providing effective suppression of voltage spikes up to 137 V (clamping voltage). It offers a peak pulse current (Ippm) of 4.4 A and low leakage current of 1 μA, operating reliably over a wide temperature range from -55°C to 150°C.

The glass passivated chip junction and low incremental surge resistance enable very fast response times and excellent surge protection characteristics. Compliant with the automotive industry standard AEC-Q101, it is suitable for applications in automotive, industrial, telecommunications, and consumer electronics, protecting ICs, MOSFETs, sensors, and other sensitive circuits.

Physical dimensions are compact at 4.57 mm length, 3.94 mm width, and 2.24 mm height, facilitating space-efficient PCB layouts. The diode's robust design and high reliability make it an ideal choice for transient voltage suppression in demanding environments.

This TVS diode is commonly employed in safeguarding electronic systems against voltage spikes caused by inductive load switching and lighting events.

It is widely used for protecting integrated circuits, MOSFETs, and signal lines of sensor units in consumer electronics, computer systems, industrial equipment, and telecommunications.

The component's small footprint and surface mount construction make it suitable for automated manufacturing assembly lines. Its uni-directional configuration is preferred for protecting circuits where voltage transients occur in a single polarity.

Meeting automotive quality standards enlarges its applicability to vehicle electronic systems requiring transient voltage protection.
