BZX584B5V6-TP Equivalent & Substitute Parts

Part Overview

The BZX584B5V6-TP is an active Zener diode manufactured by Micro Commercial Co, designed for surface mount applications in the SOD-523 package. This component operates at a nominal Zener voltage of 5.6 V with a maximum power dissipation of 150 mW. The part is RoHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial applications across an operating temperature range of -55°C to 150°C.

Substitute parts are identified when equivalent electrical performance can be achieved through components with compatible voltage ratings, power handling capabilities, and package specifications. Alternative sources become necessary due to inventory availability, supply chain considerations, or application-specific requirements such as automotive qualification or enhanced power ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for Zener diodes is determined by alignment across the following critical parameters:

Voltage Compatibility: The nominal Zener voltage must fall within the tolerance band of the application circuit. The BZX584B5V6-TP operates at 5.6 V ±1.96%. Substitute parts with nominal Zener voltages of 5.61 V and ±2% tolerance remain functionally equivalent within typical circuit design margins.

Power Dissipation: The maximum power rating of the substitute must equal or exceed the application requirement. The BZX584B5V6-TP is rated at 150 mW. Substitute parts with equal or higher power ratings (such as 500 mW) are acceptable and provide additional design margin.

Package and Mounting: Both the main part and substitutes must use identical package specifications (SOD-523) and mounting technology (surface mount) to ensure mechanical and electrical compatibility on the PCB.

Electrical Characteristics: Impedance, reverse leakage current, and forward voltage parameters must be equivalent or superior to maintain circuit performance.

Compliance and Temperature Range: RoHS3 compliance and operating temperature specifications must support the intended application environment.

MM5Z5V6ST1G as Primary Substitute

The MM5Z5V6ST1G from onsemi is a direct functional equivalent to the BZX584B5V6-TP. Both components share identical package specifications (SOD-523), mounting technology (surface mount), and core electrical characteristics including impedance, reverse leakage current, and forward voltage parameters.

The substitute offers the following advantages:

Zener voltage of 5.61 V falls within acceptable tolerance margins relative to the 5.6 V nominal specification, with both parts maintaining ±2% or better tolerance bands.

Maximum power dissipation of 500 mW exceeds the 150 mW requirement of the main part, providing additional thermal margin in power-limited applications.

Operating temperature range of -65°C to 150°C extends the lower temperature limit by 10°C compared to the main part, supporting applications requiring enhanced cold-temperature performance.

Both parts maintain RoHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and active product status, ensuring long-term availability and regulatory alignment.

The MM5Z5V6ST1G carries AEC-Q101 automotive qualification, making it suitable for automotive and mission-critical applications where enhanced reliability standards are required.

Selection Criteria

Choose the MM5Z5V6ST1G when automotive-grade components or enhanced power dissipation capability are required. The substitute is electrically and mechanically interchangeable with the BZX584B5V6-TP in standard industrial applications. Both parts are suitable for direct PCB substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the MM5Z5V6ST1G replace the BZX584B5V6-TP in existing designs?

A: Yes. Both components use the SOD-523 package, identical mounting technology, and equivalent electrical characteristics. The 5.61 V nominal Zener voltage of the substitute falls within acceptable tolerance margins for circuits designed around the 5.6 V specification. Direct PCB substitution is possible without circuit modification.

Q: What is the significance of the higher power rating (500 mW vs. 150 mW) in the substitute?

A: The higher power rating provides additional thermal margin and allows the substitute to operate safely in applications with higher power dissipation requirements. In circuits designed for 150 mW operation, the 500 mW rating of the substitute does not negatively impact performance and may extend component life through reduced thermal stress.

Q: Are there differences in tolerance between the main part and substitute?

A: The BZX584B5V6-TP carries ±1.96% tolerance, while the MM5Z5V6ST1G carries ±2% tolerance. Both tolerances are sufficiently tight for standard voltage regulation and protection applications. The 0.04% difference is negligible in typical circuit design margins.

Q: Does the extended temperature range of the substitute (-65°C vs. -55°C) affect compatibility?

A: No. The extended lower temperature limit of the MM5Z5V6ST1G (-65°C) is a superset of the main part's range (-55°C). The substitute is fully compatible with applications operating within the -55°C to 150°C range and provides additional capability for cold-temperature environments.

Q: What is the relevance of AEC-Q101 qualification on the substitute?

A: AEC-Q101 is an automotive industry qualification standard indicating enhanced reliability testing and quality assurance. The MM5Z5V6ST1G meets this standard, making it suitable for automotive applications, industrial control systems, and other mission-critical environments where higher reliability standards are required. The main part does not carry this qualification but remains suitable for standard commercial applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the BZX584B5V6-TP and MM5Z5V6ST1G are RoHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1), meeting current environmental and reliability standards for industrial and commercial electronics.

Q: Can the substitute be used in high-frequency or high-speed switching applications?

A: Impedance specifications are identical (40 Ohms maximum) for both parts. Frequency response and switching characteristics are determined by impedance and package parasitics. Both components are suitable for applications within the electrical specifications provided. Application-specific performance validation is required for specialized high-frequency designs.

Q: What inventory considerations apply to these parts?

A: The BZX584B5V6-TP has 1,083 pieces in stock. The MM5Z5V6ST1G has 20,200 pieces in stock, providing significantly higher availability. For applications requiring immediate delivery or large-volume procurement, the substitute offers superior supply chain flexibility.
