Introduction of SMLJ6.5AE3/TR13 TVS-Diodes

The SMLJ6.5AE3/TR13 is a Transient Voltage Suppressor (TVS) diode from Vishay. It has been designed to protect sensitive electronic components such as microcontrollers (MCUs), Telecom power systems, sensitive industrial equipment and industrial applications. As with all TVS diodes, it is designed to protect equipment and systems from voltage spikes and other attempts to introduce destructive energy into an electrical system.

Application Field

TheSMLJ6.5AE3/TR13 provides transient voltage protection in high voltage systems such as Telecom, industrial, medical, and computer applications. The diode works in applications with up to 250V surge voltage. It is designed for use in systems with high level of noise, as it protects against electromagnetic disturbances. It is especially suitable for Telecom power systems, as it provides high surge protection of up to 6.5 and 8 kA (typical and maximum ).It can also be used in industrial and consumer electronic systems such as inverters, uninterruptible power supplies (UPS) and power supplies. In addition, the diode can be applied to automotive uses and is also suitable for use in portable electronics such as notebooks, phones and handheld devices.

Working Principle

The SMLJ6.5AE3/TR13 functions by “shunting” the transient voltage (surge or spike) away from sensitive components and to ground. When a transient voltage begins to rise, the diode is triggered and becomes conductive. This allows the voltage to be dissipated through the diode and safely neutralized before it ever reaches the sensitive components of the system.In order to function effectively, TVS diodes must have low capacitance and fast response time. The SMLJ6.5AE3/TR13 features a low capacitance of 5pF Max., as well as a low turn-on voltage (4V max.) and a fast response time of < 50ns. These features help the diode to provide optimal protection against overvoltage transients.The diode also features a low thermal resistance of 2.5°C/W that helps to ensure that it does not overheat in the event of a surge. This helps to increase the diode’s lifespan and ensure reliable operation.

Conclusion

The SMLJ6.5AE3/TR13 is a versatile Transient Voltage Suppressor (TVS) diode from Vishay. It has been designed to protect sensitive electronic components from voltage surges and other destructive energy in high voltage electrical systems with up to 250V surge voltage. It features a low turn-on voltage and fast response time, and a low thermal resistance of 2.5°C/W that helps to ensure reliable operation. It is suitable for use in telecom power systems, industrial and consumer electronics, and automotive. All of these features make the SMLJ6.5AE3/TR13 an excellent choice for protection against voltage transients and power surges.
