Introduction to SMLJ90CE3/TR13 TVS - Diodes

Transient Voltage Suppressors (TVS) are a type of semiconductor component designed to protect sensitive electrical components from electrical overstress. Transient Voltage Suppressor Diodes, or TVS – Diodes, are a type of TVS component that are widely used in circuit protection applications. The SMLJ90CE3/TR13 is a high-reliability, unidirectional TVS – Diode designed to protect sensitive circuits against overvoltage transients.

Application Fields for SMLJ90CE3/TR13 TVS – Diodes

The SMLJ90CE3/TR13 is a popular choice for the protection of automotive electronic circuits, as it has an operating temperature range of -55 °C to + 150 °C and a peak surge current rating of 18 Amperes. This makes it ideal for use in applications such as automotive systems, controllers, braking systems, and other circuits that rely on thermal management for long-term performance and reliability. The SMLJ90CE3/TR13 is also suitable for use in sensitive electrical equipment such as computers, laptops, and mobile phones, where it can protect against up to 8 kilovolts of surge protection. Additionally, the SMLJ90CE3/TR13 is suitable for use in communication systems, smart appliances, medical equipment, and consumer electronics.

The Working Principle of SMLJ90CE3/TR13 TVS – Diodes

The working principle of SMLJ90CE3/TR13 TVS – Diodes is based on a breakdown voltage principle. When a voltage applied to the diode exceeds a certain pre-determined voltage threshold, a breakdown occurs and the diode becomes conductive. This results in the suppression of the transient voltage and current, preventing damage to the connected equipment. The SMLJ90CE3/TR13 has a low clamping voltage and is designed to suppress transients up to 8 kilovolts. This is achieved due to a unique design that incorporates a unique rectifying junction. This junction provides an extremely durable structure that is able to dissipate a wide variety of overvoltage transients.Another key feature of the SMLJ90CE3/TR13 is its very low leakage current, which is less than 0.1 microamperes at 8 kilovolts. This very low leakage current helps to reduce power consumption and ensures that the connected equipment is not subjected to any significant additional heat. The SMLJ90CE3/TR13 also features a very fast response time, with a response time of less than 0.002 nanoseconds for a 1.5 kilovolt transient. This rapid response time helps to ensure that all transients are suppressed in a timely fashion and that connected equipment receives adequate protection against electrical overstress.

Conclusion

In conclusion, the SMLJ90CE3/TR13 is a high reliability, high performance unidirectional TVS – Diode suitable for use in a wide range of circuit protection applications. Its ability to handle up to 8 kilovolts of surge protection and its low leakage current provide effective protection against electrical overstress. The SMLJ90CE3/TR13 is an ideal choice for applications where reliable circuit protection is a must, such as automotive systems, controllers, braking systems, computers, communication systems and medical equipment.
