Transient voltage suppression (TVS) diodes are designed to protect sensitive circuits against potentially damaging electrostatic discharge (ESD) and surge voltages. They are commonly used in automotive, telecommunications and consumer electronic applications as well as in industrial systems. The SMCJ6.5AHE3/9AT is a unidirectional TVS diode rated for transient suppression up to 6.5 volts and 3,000 amperes peak pulse current.

The SMCJ6.5AHE3/9AT provides protection for sensitive circuits by limiting the maximum clamping voltage so the device can absorb and dissipate the often destructive energy of an ESD or surge event. The device is specifically designed for over voltage protection for systems such as wires, cables, and printed circuit boards (PCB). With a fast response time and low clamping voltage, the SMCJ6.5AHE3/9AT is an ideal choice for protection against ESD, lightning, and other surge events.

The SMCJ6.5AHE3/9AT TVS diode offers exceptional low surge current and can clamp the voltage from surges in a wide range of frequencies. This makes it suitable for applications with high power dissipation requirements, such as a wide range of power supply, automotive, and general-purpose products. It also offers great over voltage protection characteristic, low leakage current and good clamping efficiency.

In operation, the diode is reverse-biased and any positive switching transients will reverse bias the diode, allowing current to flow until the voltage returns to normal level. Its reverse breakdown voltage, also known as stand-off voltage, is critical in determining the amount of surge current needed to ensure device protection as the breakdown voltage defines the beginning of conduction in the diode.

The SMCJ6.5AHE3/9AT is a lead-free, surface mount diode with cathode indicated by a polarity band. It is supplied in a 6.5mm body size, ideal for applications where space is an issue. It can be soldered directly onto the board without any special assembly techniques, such as hot air or infrared re-flow soldering. Furthermore, its extended range of operating and storage temperature, humidity, and vibration makes it suitable for extreme environmental conditions.

The SMCJ6.5AHE3/9AT diode has a maximum reverse Stand-off voltage of 6.5 V and can handle peak energies of 200W, with a maximum clamping voltage at a specified peak pulse current of 334 V, maximum clamping voltage at 3,000 A of 990 Volts, and a maximum clamping current of 3000A. It is capable of withstanding repetitive ESD strikes up to 25kV (HBM) and offers excellent power handling capability with extremely low leakage current.

The SMCJ6.5AHE3/9AT is designed to provide efficient surge protection for a variety of applications, including automotive, communications and consumer electronic devices. With its compact package size, low leakage current, and high peak pulse current capabilities, the SMCJ6.5AHE3/9AT is the ideal choice for applications that require reliable surge protection.
