The SM03C with 13V 4V 3.3V SOT-23 TVS ROHS is an electronic protection device manufactured by Microdiode Electronics. It is a transient voltage suppression diode in a small surface mount package. It offers superior transient voltage protection for very high densities in order to meet the more stringent safety requirements of today's electronics. The SOT-23 package is compliant with RoHS, making it suitable for various environmental regulations. It is available in a 3.3V, 4V, and 13V voltage range, with a single working peak voltage (Vp) of 18V, and a breakdown voltage of ~12V@100mA. The SM03C has a fast response time of less than 1 nanosecond and a low clamping voltage over a wide operating temperature range (-55 to +125°C). Its high ESD protection rating at the pins also ensures that it provides robust protection against electrostatic discharge (ESD) related failures.
