TVS diodes, or Transient Voltage Suppressors, are commonly used to protect electric devices from transient over voltages and circuit spikes. The CD214A-T70ALF is one such type of TVS diode, which is commonly used to protect automotive electronics, such as ECUs. This article will discuss the application fields and working principles of the CD214A-T70ALF.
The CD214A-T70ALF is a dual-diode, unidirectional device with an operating voltage range of 7V to 70V and a maximum stand-off voltage of 65V. It’s reverse stand-off voltage is 5V, with a low leakage current of 10nA. The CD214A-T70ALF’s peak pulse power dissipation is 600W (10/1000µs) and its clamping voltage is 140V. It has a maximum AC/DC diode capacitance of 1.5pF, and its maximum AC/DC diode voltage is 0.5V.
The CD214A-T70ALF is primarily used in automotive ECU and Electronic Control Units (ECUs), as it provides protection from transients. This diode is also used in in-vehicle networks, thanks to its low leakage current, high peak pulse power and its wide operating voltage range. Additionally, the CD214A-T70ALF can be used for ionizing radiation protection, as it is rated to protect from both Class B and Class C radiation.
The basic working principle of the CD214A-T70ALF is a rectifying circuit designed to limit voltage swings to an acceptable level. The CD214A-T70ALF is designed to protect the device from both positive and negative voltage transients. When the voltage transient reaches a pre-determined voltage threshold, it triggers the diode, and it works like a switch, diverting the surge away from the sensitive components and discharging it to ground. This limits the surge voltage level to an acceptable level and prevents further damage to the device.
In conclusion, the CD214A-T70ALF is a dual-diode TVS diode that is primarily used to protect automotive ECUs and Motor Control Units from transients. It has a wide operating voltage range, low leakage current and high peak pulse power capabilities, making it ideal for use in in-vehicle networks. Its basic working principle is to limit voltage swings to an acceptable level and divert surge voltages to ground.
