CDSOT23-SM712常被應(yīng)用于RS-485接口中，保護(hù)RS-485接口免受靜電放電的損壞。近年來，不少客戶帶著國際品牌（比如：伯恩斯BOURNS、力特LITTELFUSE、威世VISHAY、安森美ON、SEMTECH、PROTEK、意法ST等等）物料來尋找替代，比如替代CDSOT23-SM712、LC3311CCW、SZESD7241N2T5、RCLAMP1521PQTCT、ESDCAN05－2BWY等等。

那么，東沃電子哪顆料能夠pin to pin替代CDSOT23-SM712呢？查看東沃電子ESD二極管產(chǎn)品選型手冊可知，東沃（DOWO）品牌供應(yīng)的SM712靜電放電（ESD）保護(hù)器件pin to pin替代CDSOT23-SM712（伯恩斯BOURNS）。查看東沃（DOWO）SM712產(chǎn)品手冊可知：

1)峰值脈沖功率 (tp= 8/20 μs): 400W

2)峰值脈沖電流（8/20 μs）: 12A

3)最小擊穿電壓@ 1 mA: 7.5V and 13.3V

4)工作電壓: 7V and 12V

5)鉗位電壓@ IPP = 12A: 26V

6)漏電流@ VWM: 1uA

7)結(jié)電容 @ 0 V, 1 MHz: 45pF

8)封裝形式：SOT-23

市場對(duì)于RS-485靜電防護(hù)器件SM712需求非常大，很多供應(yīng)廠商沒有現(xiàn)貨，或者交期很長，東沃電子針對(duì)這顆料號(hào)，常年備有庫存、交期迅速、品質(zhì)卓越，最關(guān)鍵的是，價(jià)格也是非常地有優(yōu)勢
