BZX84W-B75F Equivalent & Substitute Parts

Part Overview

The BZX84W-B75F is an active Zener diode manufactured by Nexperia USA Inc., designed for voltage regulation and protection applications. This surface mount component operates at a nominal Zener voltage of 75 V with a maximum power dissipation of 275 mW in the SOT-323 package. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard manufacturing environments. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution of the BZX84W-B75F is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

• Voltage - Zener (Nom): 75 V
• Tolerance: ±2%
• Power - Max: 275 mW
• Impedance (Max): 255 Ohms
• Current - Reverse Leakage @ Vr: 50 nA @ 52.2 V
• Voltage - Forward (Max) @ If: 900 mV @ 10 mA
• Operating Temperature: 150°C (TJ)
• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount

All substitute parts must maintain identical compliance certifications (ROHS3, REACH Unaffected) and moisture sensitivity ratings (MSL 1). Packaging format (Tape & Reel) and series designation (BZX84W) remain consistent across all equivalent parts.

Parameter Comparison

Engineering Selection Recommendations

Both the BZX84W-B75F and BZX84W-B75X are active products from Nexperia USA Inc. with identical electrical specifications and compliance certifications. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation.

The BZX84W-B75X offers higher inventory availability (3848 pieces) compared to the BZX84W-B75F (716 pieces), making it suitable for high-volume production runs or extended lead-time mitigation. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in all applicable markets.

The identical SOT-323 package footprint, mounting type, and thermal characteristics ensure direct PCB-level substitution without design modification. Both parts operate within the same temperature range and maintain equivalent electrical performance across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can BZX84W-B75X be used as a direct replacement for BZX84W-B75F?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including Zener voltage (75 V), power rating (275 mW), impedance (255 Ohms), and SOT-323 package configuration. Direct substitution is supported without circuit modification.

Q: Are there differences in compliance or regulatory status between these parts?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

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

A: The suffix designates the packaging or tape reel configuration variant within the BZX84W-B75 product line. Both suffixes represent the same electrical component with identical specifications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The identical electrical parameters, package type, and mounting configuration enable direct interchangeability in PCB designs without layout or schematic modification.

Q: Are there any thermal or performance differences between these substitutes?

A: No. Both parts operate at the same maximum junction temperature (150°C) and maintain identical thermal and electrical performance characteristics across the specified operating range.
