SMBJ90A Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The SMBJ90A is an active Transient Voltage Suppressor (TVS) diode manufactured by KYOCERA AVX, designed for general-purpose transient voltage protection in surface-mount applications. This unidirectional zener diode operates with a 90V reverse standoff voltage and provides 146V maximum clamping voltage at peak pulse current. The component is housed in a DO-214AA SMB package and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). With 300,200 pieces in current inventory and active product status, equivalent and substitute parts are available from alternative manufacturers to support supply chain flexibility and procurement optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ90A is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 90V
• Voltage - Breakdown (Min): 100V
• Voltage - Clamping (Max) @ Ipp: 146V
• Current - Peak Pulse (10/1000µs): 4.1A to 4.11A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Unidirectional Channels: 1

All substitute parts listed maintain these electrical and mechanical specifications within the allowed tolerances for direct circuit-level replacement. Packaging format (Tape & Reel vs. bulk) does not affect electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full ROHS3 compliance with REACH unaffected designation. The SMBJ90A from MDD provides direct electrical and mechanical equivalence with identical voltage and power specifications. The SMBJ90A-13-F from Diodes Incorporated, designated as manufacturer-recommended, offers the same electrical performance with extended temperature range matching the original KYOCERA AVX specification (-55°C to 150°C). Selection between these substitutes should be based on procurement availability, lead time requirements, and packaging format preference (Tape & Reel vs. standard inventory packaging).

Frequently Asked Questions (FAQ)

Q: Can SMBJ90A from MDD be used as a direct replacement for KYOCERA AVX SMBJ90A?

A: Yes. Both parts share identical voltage ratings (90V standoff, 100V breakdown minimum, 146V clamping maximum), equivalent peak pulse current (4.1A vs. 4.11A), matching 600W peak pulse power, and identical DO-214AA SMB package specifications. Both are ROHS3 compliant with MSL 1 rating.

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

A: Both parts are electrically equivalent with identical voltage and power specifications. The primary difference is the manufacturer (Diodes Incorporated vs. KYOCERA AVX) and packaging format. SMBJ90A-13-F is supplied in Tape & Reel format, while standard SMBJ90A may be supplied in alternative packaging. Operating temperature ranges are -55 to 150°C for both.

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

A: Yes. All listed parts use the DO-214AA SMB package with identical surface-mount footprint and land pattern requirements. No PCB redesign is necessary for substitution.

Q: Do substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating, matching the original KYOCERA AVX SMBJ90A specifications.

Q: What is the acceptable tolerance range for peak pulse current when substituting?

A: The specified peak pulse current range is 4.1A to 4.11A at 10/1000µs pulse width. All listed substitutes fall within this range and are electrically interchangeable.
