In an electronic circuit, in order from lightning or other transient voltage events voltage transients, electrical engineers often chosen TVS TVS diode designed to protect sensitive electronic equipment. 1.5KE series TVS tube, an extremely wide range of applications, high frequency of use. So what about 1.5KE transient suppression diodes, you know how much? Which produced TVS diode 1.5KE6.8CA good?
Professional protection devices suppliers DOW electronic independent research and development, production and sales of TVS diode 1.5KE series, for example:
peak pulse power at • 10 / 1000μs waveform is 1500W, repetition rate (duty cycle): 0.01%
• DO- glass passivated chip junction 201 package
• fast response time: from 0 volts to VBR minimum typically less than 1.0ps
• excellent clamping capability
• typical failure mode is a short circuit due to exceeding the specified voltage or current caused
• tin wire based test JEDEC JESD201A in table 4a and 4c.
• IEC-61000-4-2 ESD 30kV (Air ), 30kV ( discharge contacts).
• Data Line ESD protection according to IEC 61000-4-2
• Data Line protection conforming to IEC 61000-4-4 EFT
low incremental surge resistance •
• standard case, when the minimum value of VBR> 12V, IR of less than 1 [mu

vulnerable circuits • industrial and consumer electronics products
DOW 1.5KE6.8CA difference with Vishay 1.5KE6.8CA-E3 / 54's:
Currently, the market has chosen Vishay company 1.5KE6.8CA-E3 / 54 TVS two-way pipe to make lightning protection design, but for many customers because Vishay long cycle and high prices of goods, often choose a shorter lead times, good price, cost-effective alternative: DOW electronic supply of TVS tube 1.5KE6.8CA, lowest cost can be reduced to 30%.
As can be seen from the figure 2 products electrical parameter table can be seen that the DOW 1.5KE6.8CA Vishay 1.5KE6.8CA-E3 / 54 consistent electrical parameters, are used DO-201 package realize pin -pin compatible design, without changing any external circuit. Except that the DOW having 1.5KE6.8CA can withstand higher peak pulse current of 144.8A and 15 ℃ / W Typical lower junction - better thermal resistance wire electrical parameters.
In addition to the excellent advantages typical parameters, DOW 1.5KE6.8CA also has more advantages:
1) Data Line 61000-4-2 ESD protection according to IEC;
2) Data Line EFT protection according to IEC 61000-4-4;
3) lower cost, compared to the Vishay 1.5KE6.8CA-E3 / 54 can be reduced at least 30%;
4) better delivery period, and follow-up samples allows quick production services;
5) better service experience, from design, product selection, testing one-stop shop to meet customer needs, while also based on customer demand for personalized custom.
