Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZX584B24 is determined by equivalence across the following critical parameters:

Zener voltage specification (24 V nominal), voltage tolerance (±2%), maximum power dissipation (150 mW), impedance rating (70 Ohms maximum), reverse leakage current (100 nA @ 16.8 V), forward voltage drop (900 mV @ 10 mA), operating temperature range (-55°C to 150°C), surface mount mounting type, and SOD-523F package configuration.

The substitute part BZX584B24 RSG maintains identical electrical specifications and package form factor. The primary distinction is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Cut Tape (CT) & Digi-Reel® format. Both parts are manufactured by Taiwan Semiconductor Corporation and carry Active product status with full RoHS3 and REACH compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the BZX584B24 and BZX584B24 RSG are Active products with identical electrical and thermal specifications. Selection between these parts is based on packaging and supply chain requirements rather than functional performance.

The BZX584B24 in Tape & Reel format is appropriate for high-volume automated assembly operations requiring continuous reel feeding. The BZX584B24 RSG in Cut Tape & Digi-Reel® format accommodates lower-volume production runs, manual assembly processes, and applications requiring smaller quantity procurement.

Both parts maintain full compliance with RoHS3 and REACH regulations. The substitute part includes Moisture Sensitivity Level (MSL) 1 classification, indicating unlimited shelf life without moisture control requirements. Either part is suitable for replacement in existing designs without circuit modification, provided the packaging format aligns with assembly equipment capabilities.

Frequently Asked Questions (FAQ)

Q: Can BZX584B24 RSG be used as a direct replacement for BZX584B24?

A: Yes. Both parts are electrically and thermally identical with matching 24 V nominal Zener voltage, ±2% tolerance, 150 mW power rating, and SOD-523F package configuration. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®), which does not affect circuit performance.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging provides components in shorter tape segments or alternative reel formats, typically used for lower-volume production or manual assembly processes.

Q: Are both parts RoHS3 compliant?

A: Yes. Both BZX584B24 and BZX584B24 RSG are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the operating temperature range for these Zener diodes?

A: Both parts operate across -55°C to 150°C junction temperature range, suitable for industrial and extended temperature applications.

Q: Does the substitute part have any moisture sensitivity limitations?

A: No. The BZX584B24 RSG carries Moisture Sensitivity Level (MSL) 1 classification, indicating unlimited shelf life without moisture control or baking requirements prior to assembly.

Q: Are the electrical characteristics identical between the two parts?

A: Yes. Both parts share identical Zener voltage (24 V), tolerance (±2%), maximum power dissipation (150 mW), impedance (70 Ohms), reverse leakage current (100 nA @ 16.8 V), and forward voltage drop (900 mV @ 10 mA) specifications.
