SA70CA-E3/54 Circuit Protection

The SA70CA-E3/54, part of the TVS – Diodes family of components, is a bi-directional low capacitance transient voltage suppressor (TVS) diode intended to protect a variety of low voltage data and transmission lines. This product provides fast clamping and high peak power capacity in an ultra low profile surface mount package. Its features make the SA70CA-E3/54 the perfect solution to many applications where space is limited.

The SA70CA-E3/54 is designed to protect low voltage data and transmission lines from transient voltage changes that can occur with electrostatic discharge, electrical fast transients, and / or cable coupling. Excessive voltage or electrical noise on a signal line can cause data disruption or system failures.

With a fast response time and a low capacitance this device offers many advantages over traditional unidirectional devices. The SA70CA-E3/54 has been designed to meet the SAEJ1113, UL1577, EN 60950-1, IEC 60950-1, RoHS, and Reach compliance specifications making it the ideal choice for a variety of applications.

The SA70CA-E3/54 features an ultra-low profile surface mount package, with a maximum profile height of 1.35mm, and a low parasitic capacitance of only 2.5pF per pin. This makes the SA70CA-E3/54 an ideal solution for applications with limited space requirements. Its superior performance makes the SA70CA-E3/54 well suited for a variety of industries including automotive, industrial, consumer electronics, telecommunications, and computing systems.

The SA70CA-E3/54 utilizes a semiconductor junction to provide the protection. The semiconductor junction consists of an N-type layer that is sandwiched between P-type layers. This arrangement of layers allows the diode to control the voltage by blocking the high-end voltages and allowing low voltages to pass through. This feature provides bidirectional protection.

The SA70CA-E3/54 also features a high peak power capacity of 2000W at 10/1000μseconds and a maximum reverse leakage current of 1mA at 25°C. This high peak power capacity makes this device well suited for applications such as high-speed processor interfaces, memory modules, automotive systems, and any other device exposed to electrical noise. This device can operate in temperatures between -55°C and +125°C.

In summary, the SA70CA-E3/54 is a bi-directional, low capacitance transient voltage suppressor (TVS) diode designed to protect a variety of low voltage data and transmission lines from transient voltage changes. With its ultra-low profile surface mount package, fast response time, and high peak power capacity, the SA70CA-E3/54 is quickly becoming the go-to choice for applications requiring a fast response time and superior protection.
