TVS – Diodes are a type of electrical component that are used to protect circuits or devices against a variety of peak voltages or electrical transients, such as lightning, electrical surges or other high-energy events. The 1KSMBJ39CA device is a transient voltage suppressor diode that is specifically designed to provide protection to low-power applications.The 1KSMBJ39CA is designed to protect against transient voltages ranging from 6V to 39V with a maximum leak current of 500µA at 83°C. It has an internal ESD (electrostatic discharge) protection of up to 8kV and can handle up to 13A of transient current with a standoff voltage of 36V. It is rated to work up to -65°C to +175°C, making it suitable for a wide range of applications and temperatures.This device is commonly used in industrial, automotive, and consumer electronics applications. In these applications, the 1KSMBJ39CA provides an effective level of protection against high voltage spikes and transients that might otherwise damage sensitive components or circuits. This protection is achieved through a combination of the low breakdown voltage of the device, as well as its low clamping voltage.When exposed to a transient voltage above its breakdown threshold, the 1KSMBJ39CA works in a similar way to a traditional Zener diode. When the breakdown voltage is exceeded, the diode begins to conduct current, which instantaneously “clamps” the voltage across it to a preset level. This clamping action helps to prevent further damage to the circuit or device being protected by limiting the peak voltage across it.In addition to providing protection against voltage spikes, the 1KSMBJ39CA also provides ESD protection of up to 8kV, thanks to its internal ESD network. This helps to protect against the sudden surges of static electricity that can occur when the device is handled, or when it is exposed to electrical storms.The 1KSMBJ39CA is a relatively inexpensive and versatile protection device. Its low breakdown voltage and clamping voltage make it suitable for use in many types of applications, while its ESD protection makes it a great choice for systems that are regularly exposed to static electricity. With its low power consumption and wide temperature range, the 1KSMBJ39CA is an ideal choice for low-power applications that require a reliable and cost-effective level of protection.
