BZX584B16 Equivalent & Substitute Parts

Part Overview

The BZX584B16 is an active-status zener diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the SOD-523F package. This 16 V, 150 mW zener diode operates across an industrial temperature range of -55°C to 150°C and maintains ±2% voltage tolerance. The part is ROHS3 compliant and REACH unaffected, making it suitable for regulated electronic applications requiring voltage regulation and transient protection in compact form factors.

Substitute parts are identified when equivalent electrical parameters, mechanical compatibility, and regulatory compliance align with the main part specification, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BZX584B16 are qualified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

Electrical Parameters (Must Match):

• Voltage - Zener (Nominal): 16 V
• Power - Maximum: 150 mW
• Tolerance: ±2%
• Impedance (Maximum): 40 Ohms
• Current - Reverse Leakage @ Vr: 100 nA @ 11.2 V
• Operating Temperature Range: -55°C to 150°C

Mechanical Parameters (Must Match):

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

Regulatory Compliance (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

All identified substitutes meet these criteria and are therefore electrically and mechanically interchangeable with the main part in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BZX584B16, BZX584B16 RSG, and BZX584B16HE3-TP—are active-status products with full ROHS3 compliance and REACH unaffected status, confirming regulatory alignment for current and future applications.

BZX584B16 RSG is a parametric equivalent from Taiwan Semiconductor Corporation, differentiated by Cut Tape and Digi-Reel packaging. This variant maintains identical electrical specifications and is suitable for applications where alternative packaging formats are acceptable.

BZX584B16HE3-TP is manufactured by Micro Commercial Co and includes automotive-grade qualification under AEC-Q101 standard. This part carries additional qualification for automotive applications while maintaining all core electrical parameters. Selection of this variant is appropriate for automotive or mission-critical environments requiring AEC-Q101 certification.

Selection between these substitutes depends on packaging requirements, supply chain availability, and application-specific qualification needs rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can BZX584B16 RSG replace BZX584B16 in production?

A: Yes. BZX584B16 RSG is a parametric equivalent with identical electrical specifications, operating temperature range, and regulatory compliance. The difference is packaging format: BZX584B16 is supplied in Tape & Reel, while BZX584B16 RSG is supplied in Cut Tape and Digi-Reel. Both are surface mount SOD-523F packages and are electrically interchangeable.

Q: What is the difference between BZX584B16HE3-TP and the other substitutes?

A: BZX584B16HE3-TP is manufactured by Micro Commercial Co and carries AEC-Q101 automotive qualification. Electrically and mechanically, it matches the main part and other substitutes. The distinction is the automotive-grade qualification, making it suitable for automotive applications where AEC-Q101 certification is required.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the SC-79, SOD-523 package format for surface mount assembly. PCB footprints designed for BZX584B16 accommodate BZX584B16 RSG and BZX584B16HE3-TP without modification.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: Voltage - Zener (Nominal) of 16 V, Power - Maximum of 150 mW, Tolerance of ±2%, Impedance (Maximum) of 40 Ohms, Current - Reverse Leakage of 100 nA @ 11.2 V, Operating Temperature Range of -55°C to 150°C, Surface Mount mounting type, SC-79/SOD-523 package, ROHS3 compliance, and REACH unaffected status. All identified substitutes meet these criteria.

Q: Can BZX584B16HE3-TP be used in non-automotive applications?

A: Yes. BZX584B16HE3-TP meets all electrical and regulatory requirements for general industrial applications. The AEC-Q101 qualification is an additional certification that does not restrict use in non-automotive circuits; it only confirms suitability for automotive environments.

Q: What is the inventory status of each part?

A: BZX584B16 has 1,074 pieces in stock. BZX584B16 RSG has 105,093 pieces in stock. BZX584B16HE3-TP has 15,212 pieces in stock. Inventory levels are subject to change and should be verified at time of procurement.
