P6SMB43CA is a bidirectional transient voltage suppressor (TVS) diode designed for surge and ESD protection applications. It features a breakdown voltage range of 40.9 V to 45.2 V with 5% tolerance and a peak pulse power dissipation of 600 watts at 1 ms pulse width. The device is housed in a compact surface mount DO-214AA (SMB) package and operates over a temperature range of -55°C to +150°C. With typical fast response times of less than 5.0 picoseconds for bidirectional devices, it provides effective protection against IEC 61000-4-2 ESD, IEC 61000-4-4 EFT, and IEC 61000-4-5 surge events. This RoHS compliant and halogen-free component is ideal for portable communications, computing, and video equipment requiring compact transient protection.
