Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZX84C15TS-7-F is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Nominal Zener voltage of 15 V
• 3 independent channel configuration
• Maximum power rating of 200 mW
• Operating temperature range of -65°C to 150°C
• Forward voltage (Vf) of 900 mV @ 10 mA

Mechanical Compatibility Criteria:

• Surface mount technology
• 6-TSSOP / SOT-363 package footprint
• RoHS3 compliance
• MSL rating of 1 (Unlimited)

The MMBZ5245BTS-7-F meets all substitution criteria. While it features improved tolerance (±5% versus ±6%) and lower impedance (16 Ohms versus 30 Ohms), these represent enhanced performance characteristics that maintain full backward compatibility. The substitute part is active in production status and carries automotive-grade qualification (AEC-Q101), providing superior availability and supply chain stability compared to the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

The MMBZ5245BTS-7-F is the direct substitute for the BZX84C15TS-7-F based on the following engineering factors:

Product Status: The BZX84C15TS-7-F is obsolete, creating supply chain risk. The MMBZ5245BTS-7-F is active in production, ensuring long-term availability and procurement reliability.
