Overview of SMAJ12A-13-F by Diodes Incorporated
The SMAJ12A-13-F is a Transient Voltage Suppressor (TVS) Diode, specified at 400W with a reverse working voltage (VRWM) of 12V and a maximum clamping voltage of 19.9V. Designed for unidirectional application, it incorporates a single silicon diode element within a green, plastic SMA package, featuring 2 pins for connection. This component falls within the electronic parts subcategory of Transient Suppressors under the broader category of Diodes. The SMAJ12A-13-F stands out for its excellent clamping capability, ensuring protection against voltage spikes and surges that can occur in various electronic circuits.
This diode’s physical construction adheres to the DO-214AC (SMA) package design, identified by the industry standard JESD-30 code of R-PDSO-C2, and the manufacturer’s package code “SMA”. It has a breakdown voltage range from 13.3V to 14.7V, with a nominal value at approximately 14V. This range ensures that the device activates (or “breaks down”) only when the voltage exceeds the specified minimum, offering a safeguard for sensitive components downstream. The device operates effectively within a wide temperature range from -55°C up to 150°C, making it suitable for various challenging environments. Further, it supports a peak reflow temperature of 260°C for a maximum of 30 seconds, compatible with most lead-free soldering processes as indicated by its JESD-609 Code e3. Despite its impressive power dissipation capability up to 400W for transient spikes, its maximal power dissipation during normal operation is capped at 1W.
Diodes Incorporated certifies this component as RoHS compliant, albeit with the note of not being lead-free (“Pbfree Code: No”). It also hasn’t completed REACH compliance and is classified under ECCN Code “EAR99” and HTS Code “8541.10.00.50”. As of the current writing, the factory lead time for this part is approximately 8 weeks.
