TVS (Transient Voltage Suppressors) diodes are specialized ruggedized diodes used to protect components and systems from electrical transients. As the various types of circuit boards increase their micro-electronics, surge protection components become increasingly important and used in order to protect against electrical transients, which can include voltage transients, electrostatic discharge (ESD), and electromagnetic interference (EMI). The SMAJ36A-13-F TVS diode is one such surge protection device, designed to provide ESD and voltage transient protection, as well as EMI filtering. In this article, we discuss the application field and working principle of the SMAJ36A-13-F.

The SMAJ36A-13-F is a unidirectional TVS diode that can handle 36V power potentials and 13A of surge current. This makes the SMAJ36A-13-F well-suited to a variety of application fields, including USB / IEEE 1394, Telecom, Industrial and Automotive Electronics, Consumer Electronics, and Computer Systems. In all of these application fields, the SMAJ36A-13-F is used to provide surge protection, ESD protection, and EMI filtering.

The SMAJ36A-13-F is designed to protect microelectronic components from overvoltage conditions. It does this by clamping and dissipating transients as part of an ESD protection network. In a basic circuit diagram, SMAJ36A-13-F can be seen to perform this clamping by providing a path to ground when a transient strikes the power line or the ground line.

When a positive transient occurs, the positive voltage will strike and forward bias the SMAJ36A-13-F, causing it to conduct current and dissipate the transient energy as heat. Then, when the transient voltage drops, the diode is reversed biased and stops conducting. This clamping action of the SMAJ36A-13-F allows for the protection of sensitive components by dissipating the transient energy and preventing it from reaching downstream components.

Besides ESD protection, the SMAJ36A-13-F also provides EMI (electromagnetic interference) protection. This is done by creating a low pass filter that blocks high frequency noise, and by utilizing the reverse protection action of the SMAJ36A-13-F to provide an impedance path to ground for any high frequency noise on the power line or ground line. The SMAJ36A-13-F is a valuable device in applications where EMI noise poses a threat.

In addition, the SMAJ36A-13-F has a wide temperature range, from -55 ℃ to + 125℃, allowing it to operate in both industrial and automotive settings. It is also very small, with a RoHS compliant, halogen free, UL recognized SOD-123 FL package. This package makes the SMAJ36A-13-F well-suited for circuit applications where space is at a premium.

The SMAJ36A-13-F provides a variety of features and benefits for a range of applications. Its ESD protection, EMI protection, and surge protection capabilities make it ideal for protecting sensitive components, while its durable design and small size make it suitable for industrial and automotive applications. The SMAJ36A-13-F is an invaluable device for providing reliable protection against electrical transients of all sorts.
