SMBJ90A-13 Equivalent & Substitute Parts

Part Overview

The SMBJ90A-13 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated in SMB (DO-214AA) surface mount packaging. This component is designed for general-purpose transient voltage suppression applications with a 90V reverse standoff voltage and 146V maximum clamping voltage. The SMBJ90A-13 is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ90A-13 is determined by strict electrical and mechanical parameter matching:

Critical Parameters for Substitution:

• Voltage - Reverse Standoff (Typ): 90V
• Voltage - Breakdown (Min): 100V
• Voltage - Clamping (Max) @ Ipp: 146V
• Current - Peak Pulse (10/1000µs): 4.1A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Unidirectional Channels: 1

All identified substitute parts maintain identical electrical specifications and package configuration, ensuring functional equivalence in circuit applications. Differences in product status, compliance certifications, and packaging format (bulk vs. tape & reel) do not affect electrical performance.

Parameter Comparison

Engineering Selection Recommendations

SMBJ90A-13-F (Diodes Incorporated): This part is the direct equivalent of the original SMBJ90A-13, manufactured by the same supplier with identical electrical specifications and operating temperature range. The primary distinction is product status (active vs. discontinued) and packaging format (tape & reel vs. bulk). This part carries ROHS3 compliance certification, meeting current regulatory requirements. Inventory availability is significantly higher at 15,400 pieces.

SMBJ90A (MDD): This alternative from MDD manufacturer provides identical electrical performance across all critical parameters. The operating temperature range is slightly narrower (-50°C to 150°C versus -55°C to 150°C), which is acceptable for most general-purpose applications. This part is ROHS3 compliant and maintains active product status with substantial inventory availability at 300,200 pieces.

Selection between SMBJ90A-13-F and SMBJ90A should be based on supply chain requirements, preferred manufacturer qualification, and inventory lead times. Both parts are functionally equivalent for the specified application.

Frequently Asked Questions (FAQ)

Q: Can SMBJ90A-13-F be used as a direct replacement for SMBJ90A-13?

A: Yes. Both parts are manufactured by Diodes Incorporated with identical electrical specifications, including 90V reverse standoff voltage, 146V clamping voltage, 4.1A peak pulse current, and 600W peak pulse power. The primary difference is packaging format (tape & reel versus bulk) and product status (active versus discontinued).

Q: What is the difference between SMBJ90A-13-F and SMBJ90A from MDD?

A: The electrical specifications are identical. The MDD SMBJ90A has a slightly narrower operating temperature range (-50°C to 150°C versus -55°C to 150°C). Both parts are ROHS3 compliant and actively manufactured. Selection depends on manufacturer qualification and supply availability.

Q: Does the SMB package format differ between these parts?

A: No. All three parts use the DO-214AA SMB surface mount package with identical mechanical and electrical interface characteristics. Tape & reel packaging (SMBJ90A-13-F) and bulk packaging do not affect component performance or PCB assembly compatibility.

Q: Are there compliance differences between the original SMBJ90A-13 and its substitutes?

A: Yes. The original SMBJ90A-13 is RoHS non-compliant. Both substitute parts (SMBJ90A-13-F and SMBJ90A) are ROHS3 compliant, meeting current environmental and regulatory standards for electronic components.

Q: Which substitute part should be selected for new designs?

A: For new designs, either SMBJ90A-13-F or SMBJ90A is acceptable based on electrical equivalence. ROHS3 compliance of both substitutes makes them suitable for current manufacturing standards. Selection should consider manufacturer qualification requirements and supply chain logistics.
