Posted in SEA Series

SEA Series is produced by multiple layers process. The inner electrode is printed above sheet and press the sheets to make the structure dense and sinter at high temperature through oven. At this stage, the ceramic particle will grow up and make the structure more dense and end termination at both ends eventually. We develop the overvoltage suppressors base on professional formula and production technic (acquired many international patents). It not only provides the high performance of surge protection for electronic products, but also saves the assembly cost and space limits due to SMD package. In addition, due to the excellent electric characteristics (BDV、α、Ir、Capacitance with normal distribution and low dispersion), it not only can apply in ESD protection for automotive, but also it can pass the test of ISO7637-2 pulse 1、2、3a、3b. The different capacitance of SEA series can replace traditional TVS plus two pieces of capacitors for noise filters and save cost. Therefore, the SEA series is the best choice for ESD protection for automotive electronics. Key Features: •ESD contact +/-30 kV •IEC61000-4-4 (EFT 5/50 ns) +/-4 kV •IEC61000-4-5 (Surge 8/20 us) > 10 A •Response time < 0.5 ns • Low Reverse Leakage Current (<0.1 uA) •Operating range up to 125°C. •Bi-directional clamping •Zero-inductance (SMD devices) •Lead-free electronics. •Low Capacitance High−CAN Data Rates •ISO pulse capability (ISO7637-2: 2004(E)): • Pulse 1 (max. -50 V), • Pulse 2 (max. 125 V), • Pulses 3a and 3b
