Supply of new RD-91 package BTA25-600B triac 7 days of receipt of goods and found goods have any quality problems, please contact us, let us first clear understanding of your question, we provide the appropriate question to pictures. After communication SCR, if confirmation is our product quality problems caused by human error rather than you CLA50E1200 way SCR, we agree that you get approval to return the goods; and to ensure that goods are clean and free of stains, without any artificial damage and scratches, can the new replacement, please return it when packed. Please check the delivery address when we return it. We do not accept no communication to pay return shipping way! If you insist on returning 40TPS12A way to pay for SCR, we all refused to sign and receive! Goods sent to the buyer, the buyer no quality problems, no transportation problem, unjustified BTW69 way thyristor, do not communicate with the seller shall not return, hope to understand! TYN812 12A, 800V way thyristor SCR main parameters are: the average value of a voltage, rated 50 Hz sine-state average current IT under certain conditions, between the anode cathode --- continuously through the half-wave current average. 2, the forward blocking voltage peak VPF control plus a trigger signal is not very open, not over the anode forward voltage can lead voltage, can be repeated added to both ends of the forward peak voltage thyristor. SCR withstand peak forward voltage can not exceed the value of this parameter is given in the manual. BTW69 way SCR | are fertile Electronics (certified) | SCR Dongguan City is provided by Wal-Electronic Technology Co., Ltd. Dongguan City is Wal-Electronic Technology Co., Ltd.
