Overview

The SMA4F188AY is a TV made by STMicroelectronics in a SMA-flat package with 2 pins. -55℃~+175℃ 1.4A 188V 2.5kW@8/20us 200nA 209V 328V IEC 61000-4-2、IEC 61000-4-4 TVS Unidirectional SMA-flat ESD and Surge Protection (TVS/ESD) ROHS.

PCBKit's library has its KiCad symbol (Device:D_TVS, from KiCad's library) and its footprint (EasyEDA_Cloud:SMA_L4.3-W2.6-LS5.2-FD, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C1981486).

Questions

Is there a KiCad symbol and footprint for the SMA4F188AY?

Yes. The symbol is Device:D_TVS and the footprint EasyEDA_Cloud:SMA_L4.3-W2.6-LS5.2-FD, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SMA4F188AY?

SMA-flat, with 2 pins. Its footprint is drawn on this page.

Where is the SMA4F188AY datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the SMA4F188AY?

JLCPCB lists it as part C1981486, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SMA4F188AY?

Parts like it in the library: the SMAJ188A M2G by Taiwan Semiconductor, the SMAJ188A R3G by Taiwan Semiconductor, the SMAJ188AHM2G by Taiwan Semiconductor and the SMAJ188AHR3G by Taiwan Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
