SMCJ12CA-13-F is an unidirectional and bidirectional surface mount transient voltage suppressor diode that is designed for clamping and protection against voltage transients caused by lightning, inductive switching, or other noise sources. It is commonly found in in-rush current protection, DC and AC line overvoltage protection, RF systems protection, AC fast transients protection, and signal line protection. This diode offers a wide working range with peak pulse power rating of 1.3 kW (10/1000 μs) at an ambient temperature of 25°C.

The SMCJ12CA-13-F is a Packaged in a 0.205” (5.2mm) square SMAF package. It has a low component height profile of just 0.110” (2.8mm) which makes it suitable for commercial applications with space constrictions. The device’s peak pulse power dissipation rating of 1.3kW is significantly greater than that of other diode packages with comparable footprints, rendering it an ideal fit for applications with ultra-low RDS(ON) requirements. Furthermore, the presence of an integrated clamping structure provides an extra layer of protection against extreme surge and overvoltage events.

SMCJ12CA-13-F employs proven technologies such as avalanche breakdown and zinc-oxide avalanche technology in order to provide robust transient voltage protection. Avalanche breakdown technology operates by allowing electrons to gain sufficient energy to form “electron-hole pairs.” These electron-hole pairs become bulk current carriers which help to reduce voltage overshoot. This can cause a large amount of heat to be dissipated from the junction but due to the low thermal impedance of the SMCJ12CA-13-F, this voltage suppression is easily managed within standard operating conditions.

Extremely fast clamping characteristic times of the SMCJ12CA-13-F allows transient energy to be diverted from sensitive circuit components and limit inrush current to provide overload protection. The high, stable breakdown voltage along with the rated and tested capacitance and ESD robustness of this diode also ensures superior performance in a variety of applications. The SMCJ12CA-13-F can be used in consumer electronics, automotive systems, and industrial applications. This device is characterized and tested in accordance with AEC Q101, making it RoHS compliant.

Overall, the SMCJ12CA-13-F is a versatile TVS diode offering superior bi-directional low-capacitance protection for a wide range of applications. With its low component height profile and built-in features that help resist electrical surges and transients, it is the ideal choice for a variety of electronics, including consumer electronics, automotive systems, and industrial applications.
