Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ90AE3/TR13 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• 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 or SMB
• Mounting Type: Surface Mount
• Unidirectional Channels: 1
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts maintain identical electrical performance specifications and package compatibility. Operating temperature ranges may vary within acceptable limits for general-purpose applications. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel) represents logistical variation only and does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the SMBJ90AE3/TR13. Selection among available options is determined by:

Compliance & Certification: All substitute parts carry ROHS3 compliance and REACH unaffected status, matching the original component's regulatory standing. Moisture sensitivity level remains constant at MSL 1 (Unlimited) across all options.

Product Status: All parts are active in production, ensuring continued availability and supply chain stability.

Operating Temperature Considerations: The SMBJ90AE3/TR13 operates across -65°C to 150°C. Substitute options from Diodes Incorporated (SMBJ90A-13-F) and Vishay (SMBJ90A-E3/52) operate across -55°C to 150°C, which is acceptable for general-purpose applications where the lower temperature limit does not fall below -55°C. The MDD SMBJ90A operates across -50°C to 150°C. Selection should confirm application temperature requirements do not exceed these specified ranges.

Packaging & Availability: The SMBJ90A (MDD) offers the highest inventory availability at 300,200 pieces. SMBJ90A-13-F (Diodes Incorporated) provides 15,400 pieces, and SMBJ90A-E3/52 (Vishay) provides 12,200 pieces. Packaging formats (Tape & Reel, Cut Tape, Digi-Reel) represent distribution options without affecting electrical performance.

Frequently Asked Questions (FAQ)

Q: Can SMBJ90A (MDD) directly replace SMBJ90AE3/TR13 (Microchip)?

A: Yes. Both components share identical electrical specifications: 90V reverse standoff voltage, 100V minimum breakdown voltage, 146V maximum clamping voltage, and 4.1A peak pulse current. Both use the DO-214AA (SMB) package and are RoHS3 compliant with MSL 1 rating. The operating temperature range for MDD extends to -50°C minimum, which is acceptable for applications not requiring operation below -50°C.

Q: What is the difference between SMBJ90A-13-F and SMBJ90A-E3/52?

A: Both parts are electrically identical with matching voltage and current specifications. SMBJ90A-13-F is manufactured by Diodes Incorporated and operates across -55°C to 150°C. SMBJ90A-E3/52 is manufactured by Vishay and operates across -55°C to 150°C. The primary difference is manufacturer and packaging format (Tape & Reel versus Cut Tape & Digi-Reel). Both are suitable for direct substitution.

Q: Are there any package compatibility issues when substituting these parts?

A: No. All substitute parts use the DO-214AA (SMB) package format, which is mechanically and electrically identical. Surface-mount footprints are standardized across all options, allowing direct PCB placement without modification.

Q: Does operating temperature range affect substitution suitability?

A: Operating temperature range should be verified against application requirements. The original SMBJ90AE3/TR13 operates from -65°C to 150°C. Substitute parts operate from -50°C to -55°C minimum. If the application requires operation below -50°C, the original Microchip part or parts with equivalent lower temperature limits must be selected.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification and REACH unaffected status, matching the regulatory requirements of the original component.

Q: What is the significance of the SMBJ base product number?

A: The SMBJ90 base product number indicates the 90V voltage rating class. All substitute parts share this base designation, confirming electrical equivalence within the SMBJ90 product family across different manufacturers.
