TVS (Transient Voltage Suppressor) diodes are sought after components in many electronic designs as safeguards against surges. SMAJ6.5E3/TR13, in particular, is a series of TVS diodes with a wide range of application fields and working principles.

First and foremost, the SMAJ6.5E3/TR13 series are superbly well-suited to guard against ESD (electrostatic discharge) and other surge threats related to transient voltage. Electrically speaking, they provide fast response times with low capacitance and can ensure non-destructive protection against voltage over-spikes up to 1500 W peak pulse power. The protected terminals then remain operational after the surge event has passed. These features make SMAJ6.5E3/TR13 ideal components for mission-critical systems.

From a practical point of view, SMAJ6.5E3/TR13 are decent performers in the following areas:

• Automotive Electronic Systems - Of the whole range of SMAJ6.5E3/TR13 products, many of them are particularly compatible with the harsh electrical conditions found in the automotive industry. TVS diodes from this series are therefore often subjected to rugged tests and qualified under AEC-Q101. It is important to note that all these unique TVS diodes possess a maximum junction temperature of 175°C.
• Telecommunications Equipment - SMAJ6.5E3/TR13 TVS diodes are also capable of protecting sensitive electronics from over-voltage transients related to communication networks. Devices from this series have extremely low leakage current combined with superb clamping capabilities. Plus, their low capacitance ensures fast responses to voltage spikes.
• Industrial Controllers and Components - These TVS diodes from SMAJ6.5E3/TR13 provide non-destructive protection against transients created by various sources such as inductive loads, motors, or contact protection. In addition, its broad operational temperature enables it to perform reliably in the harshest industrial conditions.

In terms of working principle, SMAJ6.5E3/TR13 TVS devices share the same behavior as any other type of TVS device. When a conducting, non-linear element is exposed to a transient voltage, it begins to conduct quickly and the sudden current increase at the point of exposure is what is known as a “clamp”. This quick current boost enables the voltage spike to be “clamped” off by the short-term surge current.

SMAJ6.5E3/TR13 TVS diodes range may vary according to the wattage power output and peak pulse power, but all of them perform extremely well in their respective fields. Their fast response coupled with robust construction capabilities make then the perfect candidate for protection from all sorts of voltage over-spikes.
