Transient voltage suppressors (TVS) are widely used circuit protection components which can help to protect your valuable equipment and critical components from the damage associated with excessive transient voltages. The 1.5KE47CA-B series is one of the most popular TVS devices on the market and can be used for a variety of applications. In this article we will explore the 1.5KE47CA-B series application field and working principle in detail.

1.5KE47CA-B series TVS are used for surge protection of different communication lines, including signals of automotive electronics, power supply and data cable protection, and audio and video signalprotection. The 1.5KE47CA-B series are designed to protect systems against destructive transient voltages which are often caused by lightning strikes, power spikes, and electrostatic discharges. They are especially useful in applications that require a high degree of surge immunity.

The 1.5KE47CA-B series TVS is composed of a semiconductor die and a ceramic chip-mounted package. The semiconductor die is constructed from a p-type junction formed between a heavily doped p+ substrate and a heavily doped n-type epitaxial layer. It has an avalanche breakdown voltage (VBR) of 47V and an operating temperature range from -55°C to 105°C.

The proprietary design of the 1.5KE47CA-B series provides an extremely fast response time to voltage transients. Typically, it can respond to transients in less than 1 ns (nanoseconds). The response time is also unaffected by the temperature or slope of the transient voltage.

The 1.5KE47CA-B series TVS also have excellent clamping performance and very low leakage current due to its low on-resistance design. The on-resistance of the device is less than 0.5Ω and the leakage current is less than 1µA at 25°C.

The 1.5KE47CA-B series also provides protection against electromagnetic interference (EMI). It has a very low capacitance of 4pF at 0V and a high capacitance of 15pF at 100V. This provides effective EMI suppression of up to 30dB at 1MHz.

In conclusion, the 1.5KE47CA-B series is a reliable, robust and efficient TVS device which is ideally suited for protecting electrical and electronic systems from excessive transient voltages. It is well suited for automotive electronics, industrial automation, military, medical and consumer applications. With its extremely fast response time, low on-resistance, low leakage current and high capacitance it provides effective protection against even the harshest transient voltages.
