Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BZX584B11-TP are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Electrical Parameters (Must Match):

• Voltage - Zener (Nom): 11 V
• Tolerance: ±2%
• Power - Max: 150 mW
• Impedance (Max): 20 Ohms
• Current - Reverse Leakage @ Vr: 100 nA @ 8 V
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 10 mA
• Operating Temperature Range: -55°C to 150°C (TJ)

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: SC-79, SOD-523 (or SOD-523F variant)

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Packaging format variations (Tape & Reel vs. Cut Tape & Digi-Reel) do not affect electrical or mechanical compatibility and are therefore acceptable substitution variables.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BZX584B11-TP, BZX584B11, and BZX584B11 RSG—meet the electrical and mechanical requirements for direct substitution. Selection among these alternatives is determined by:

Availability and Lead Time: BZX584B11 RSG (Taiwan Semiconductor Corporation) has the highest inventory at 104,644 units, followed by BZX584B11 (Good-Ark Semiconductor) at 7,061 units, and BZX584B11-TP (Micro Commercial Co) at 1,019 units.

Packaging Format: BZX584B11-TP is supplied in Tape & Reel format. BZX584B11 and BZX584B11 RSG are supplied in Cut Tape & Digi-Reel format. Packaging selection depends on assembly equipment compatibility and procurement volume requirements.

Compliance Certification: All three parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8541.10.0050).

Package Variant: BZX584B11 RSG uses SOD-523F supplier device package, while BZX584B11-TP and BZX584B11 use standard SOD-523. Both variants are mechanically and electrically compatible within the SC-79 / SOD-523 package family.

Frequently Asked Questions (FAQ)

Q: Can BZX584B11 (Good-Ark Semiconductor) be used as a direct replacement for BZX584B11-TP (Micro Commercial Co)?

A: Yes. Both parts share identical electrical parameters (11 V nominal, ±2% tolerance, 150 mW power rating, 20 Ohms impedance, 100 nA reverse leakage, 900 mV forward voltage), identical operating temperature range (-55°C to 150°C), identical package designation (SC-79, SOD-523), and identical compliance certifications (ROHS3, MSL 1). The only difference is packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) and manufacturer.

Q: What is the difference between SOD-523 and SOD-523F package variants?

A: Both SOD-523 and SOD-523F are mechanically and electrically equivalent surface mount packages within the SC-79 family. The "F" designation indicates a supplier-specific variant designation used by Taiwan Semiconductor Corporation. No functional difference exists for circuit design purposes.

Q: Are all three parts suitable for the same circuit applications?

A: Yes. All three parts meet identical electrical specifications for voltage regulation, transient suppression, and protection applications requiring 11 V Zener diodes with 150 mW power dissipation and ±2% tolerance.

Q: Does the difference in inventory levels affect part selection?

A: Inventory levels do not affect electrical or mechanical compatibility. Selection based on inventory should consider lead time requirements and procurement volume. BZX584B11 RSG offers the highest stock availability.

Q: Are there any temperature or environmental performance differences between manufacturers?

A: No. All three parts specify identical operating temperature range (-55°C to 150°C junction temperature), identical moisture sensitivity level (MSL 1, Unlimited), and identical compliance status (ROHS3 Compliant, REACH Unaffected).
