• Zener Voltage (Vz): 11 V nominal
• Tolerance: ±2%
• Maximum Power Dissipation: 275 mW
• Impedance (Zzt): 20 Ohms maximum
• Reverse Leakage Current: 100 nA @ 8 V
• Forward Voltage: 900 mV @ 10 mA maximum
• Operating Temperature: 150°C junction temperature
• Package: SOT-323 (SC-70)
• Mounting: Surface Mount
• Compliance: RoHS3, REACH Unaffected

Parts meeting all these parameters are classified as direct parametric equivalents and may be used interchangeably in circuit designs without modification.

Frequently Asked Questions (FAQ)

Q: Can BZX84W-B11X be used as a direct replacement for BZX84W-B11F?

A: Yes. Both parts are parametric equivalents with identical Zener voltage (11 V), tolerance (±2%), power rating (275 mW), impedance (20 Ohms), and package specifications (SOT-323). No circuit modifications are required.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited). Both are manufactured by Nexperia USA Inc. and maintain Active product status.

Q: What is the significance of the part number suffix (F vs. X)?

A: The suffix designates the packaging reel configuration or tape specification. Both BZX84W-B11F and BZX84W-B11X are supplied in Tape & Reel (TR) format and are functionally equivalent. The suffix does not affect electrical performance or circuit compatibility.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts use identical SOT-323 surface mount packages with the same pin configuration, footprint, and soldering requirements. Assembly processes and reflow profiles remain unchanged.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: Zener voltage (11 V), tolerance (±2%), maximum power dissipation (275 mW), impedance (20 Ohms), reverse leakage current (100 nA @ 8 V), forward voltage (900 mV @ 10 mA), operating temperature (150°C), and package type (SOT-323 surface mount).
