Frequently Asked Questions
Q: What is the difference between the SMCJ "A" and "CA" variants in this TVS diode pack?
A: The "A" suffix (e.g., SMCJ11A, SMCJ12A) denotes a unidirectional TVS diode, which clamps voltage transients in one polarity — ideal for DC circuits. The "CA" suffix (e.g., SMCJ11CA, SMCJ12CA) denotes a bidirectional TVS diode, which clamps transients in both polarities — suitable for AC lines or data/signal lines where transients can occur in either direction.
Q: What package type are these TVS diodes and are they suitable for surface-mount assembly?
A: Yes — these TVS diodes use the SMC DO-214AB package, which is a standard surface-mount (SMD) form factor. They are fully compatible with standard SMT PCB footprints and can be placed and soldered using reflow or hand-soldering techniques. Their compact size makes them ideal for modern PCB designs where space is at a premium.
Q: How many diodes are included and which part numbers are in this pack?
A: Each order contains 10 pieces. The listing covers the following part numbers: SMCJ11A, SMCJ11CA, SMCJ12A, SMCJ12CA, SMCJ13A, SMCJ13CA, SMCJ15A, and SMCJ15CA. Please check your selected variant at purchase to confirm which specific part number you are ordering.
