Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BZX84W-B3V0F are identified based on electrical parameter equivalence and mechanical compatibility. The critical parameters that determine substitution eligibility are:

• Zener voltage rating: 3 V nominal
• Tolerance specification: ±2%
• Maximum power dissipation: 275 mW
• Package type: SOT-323 (SC-70)
• Mounting configuration: Surface Mount
• Impedance (Max): 95 Ohms
• Reverse leakage current: 10 µA @ 1 V
• Forward voltage: 900 mV @ 10 mA
• Operating temperature range: 150°C (TJ)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Parts meeting all these specifications are classified as parametric equivalents and direct substitutes. The BZX84W series designation indicates a common product family with consistent electrical characteristics across variants.

Parameter Comparison
