Frequently Asked Questions (FAQ)

Q: Can BZX84W-B22F and BZX84W-B22X be used interchangeably with BZX84W-C22X?

A: Yes. Both parts share identical electrical specifications (22 V nominal, 275 mW power, 55 Ohms impedance) and mechanical compatibility (SOT-323 package, surface mount). The primary difference is tolerance: BZX84W-B22F and BZX84W-B22X carry ±2% tolerance versus ±5% for BZX84W-C22X. This tighter tolerance may provide improved voltage regulation performance in applications requiring higher precision.

Q: What is the difference between BZX84W-C22X and BZX84W-C22F?

A: Both parts carry identical electrical specifications and ±5% tolerance. The difference lies in the packaging format suffix: "X" denotes Tape & Reel packaging, while "F" also denotes Tape & Reel packaging. Both are suitable for automated assembly.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts—BZX84W-B22F, BZX84W-B22X, and BZX84W-C22F—are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the main part specification.

Q: Can these Zener diodes be used in high-temperature applications?

A: All parts in this comparison are rated for operating temperatures up to 150°C (TJ), enabling use in elevated temperature environments within this thermal limit.

Q: What is the significance of the SOT-323 package for these Zener diodes?

A: The SOT-323 package (also designated SC-70) is a surface mount package suitable for automated PCB assembly. All substitute parts use this identical package, ensuring mechanical and electrical compatibility without PCB layout modifications.

Q: Are there any compliance or regulatory differences between the main part and substitutes?
