TVS diodes are commonly used electronic components that are designed to divert or clamp surge currents from electronic circuits. The SMDA15C-7/TR13 is a unidirectional dual-channel diode array manufactured by Diodes Incorporated. It is specifically designed to protect relay coil and contact circuits by shunt diverting surge current away from sensitive relay control circuitry. In applications where the SMDA15C-7/TR13 is used, it provides protection for relay integrated circuit (IC) contact circuits against overvoltage transients originating from inductive switching loads.

The SMDA15C-7/TR13 is a double-channel array diode consisting of two integrated guard rings and integrated shielding. This device is designed to provide high surge clamping capability with a low voltage drop and fast response time. The low counter circuit parasitic capacitances make this device suitable for applications that require low capacitive loading.

The SMDA15C-7/TR13 has a typical breakdown voltage of 15V and a maximum peak surge current rating of 13A. It is offered in an ultra-small thermally enhanced package which provides efficient heat dissipation and improved electrical performance. The package dimensions are 2.0 mm x 1.6 mm with a height of 0.6 mm. This device is rated for continuous operating temperatures up to 125°C and is RoHS compliant.

The SMDA15C-7/TR13 can be used in a wide variety of applications, including AC or DC motor control, CFL inverters, UPS systems, and audio/video systems. It is widely used in automotive applications, such as on-board chargers, airbag control circuits, and diesel aftertreatment systems. It can also be found in consumer and industrial products, as well as telecom equipment.

The working principle of the SMDA15C-7/TR13 is based on the avalanche breakdown mechanism. When the voltage across the diode increases above the breakdown voltage, a large current will start to flow through the diode. The current will reach a peak before the voltage across the diode begins to decrease and the current level slowly begins to drop. This avalanche effect is what allows the SMDA15C-7/TR13 to clamp large voltage transients and divert them away from sensitive circuitry.

The SMDA15C-7/TR13 diode array provides efficient and reliable protection in high performance applications. Its low-voltage drop and fast response time make it ideal for protecting sensitive electronic circuits from overvoltage transients. It is offered in an ultra-small thermally enhanced package, making it well-suited for space-constrained applications. The wide range of applications make the SMDA15C-7/TR13 an ideal choice for protecting a variety of sensitive electronic circuits.
