CDSOT23-SM712常被应用于RS-485接口中,保护RS-485接口免受静电放电的损坏。近年来,不少客户带着国际品牌(比如:伯恩斯BOURNS、力特LITTELFUSE、威世VISHAY、安森美ON、SEMTECH、PROTEK、意法ST等等)物料来寻找替代,比如替代CDSOT23-SM712、LC3311CCW、SZESD7241N2T5、RCLAMP1521PQTCT、ESDCAN05-2BWY等等。
那么,东沃电子哪颗料能够pin to pin替代CDSOT23-SM712呢?查看东沃电子ESD二极管产品选型手册可知,东沃(DOWO)品牌供应的SM712静电放电(ESD)保护器件pin to pin替代CDSOT23-SM712(伯恩斯BOURNS)。查看东沃(DOWO)SM712产品手册可知:
1)峰值脉冲功率 (tp= 8/20 μs): 400W
2)峰值脉冲电流(8/20 μs): 12A
3)最小击穿电压@ 1 mA: 7.5V and 13.3V
4)工作电压: 7V and 12V
5)钳位电压@ IPP = 12A: 26V
6)漏电流@ VWM: 1uA
7)结电容 @ 0 V, 1 MHz: 45pF
8)封装形式:SOT-23
市场对于RS-485静电防护器件SM712需求非常大,很多供应厂商没有现货,或者交期很长,东沃电子针对这颗料号,常年备有库存、交期迅速、品质卓越,最关键的是,价格也是非常地有优势
