Co.,LTD.The SMDJ48A is a TVS (transient voltage suppressor) diode manufactured by Changjing Electronics Technology Co.,LTD with SMCG RoHS (Restriction of Hazardous Substances) certification. It is constructed with a glass passivated junction in a small surface-mount package, allowing it to be used for a variety of applications such as transceivers, digital cameras, computers, modems, portable electronics, and many others. The SMDJ48A has a working voltage of 48VPP and with its unidirectional, ultralow leakage characteristics it can protect components from ESD (electrostatic discharge) and other voltage surges up to 50 amps. Its operating temperature range is -55°C ~ +150°C and its maximum clamping voltage can be as low as 13.2. It also features low capacitance and noise performance to ensure reliable protection for sensitive components.
