Substitute Part Grouping Explanation

Substitute parts for the 1SMB7.5A TR13 PBFREE are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 7.5V
• Voltage - Breakdown (Min): 8.33V
• Voltage - Clamping (Max) @ Ipp: 12.9V
• Current - Peak Pulse (10/1000µs): 46.5A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain these core electrical specifications and package requirements, ensuring direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and full RoHS3 compliance with identical electrical performance specifications. The primary distinction is the operating temperature range: the 1SMB7.5A TR13 PBFREE supports -65°C to 150°C, while both substitute parts (SMBJ7.5A-13-F and SMBJ7.5A-E3/52) support -55°C to 150°C. For applications requiring the extended lower temperature range of -65°C, the original 1SMB7.5A TR13 PBFREE is the appropriate selection. For applications within the -55°C to 150°C range, either substitute part provides equivalent electrical and mechanical performance. Inventory availability and lead time considerations may influence final part selection among the three options.

Frequently Asked Questions (FAQ)

Q: Can SMBJ7.5A-13-F or SMBJ7.5A-E3/52 be used as direct replacements for 1SMB7.5A TR13 PBFREE?

A: Yes, both parts are direct functional equivalents for applications operating within the -55°C to 150°C temperature range. All three parts share identical voltage ratings (7.5V reverse standoff, 12.9V clamping), peak pulse current (46.5A), power dissipation (600W), and DO-214AA SMB package specifications.

Q: What is the key difference between these substitute parts?

A: The primary difference is the minimum operating temperature. The 1SMB7.5A TR13 PBFREE operates from -65°C, while SMBJ7.5A-13-F and SMBJ7.5A-E3/52 operate from -55°C. All other electrical and mechanical parameters are identical.

Q: Are all parts RoHS3 compliant?

A: Yes, all three parts are RoHS3 compliant with MSL rating of 1 (Unlimited), ensuring compatibility with modern manufacturing processes and environmental regulations.

Q: Do these parts require different PCB footprints?

A: No. All three parts use the DO-214AA (SMB) surface mount package, requiring identical PCB footprints and assembly processes.

Q: Which substitute part should I select if temperature range is not a constraint?

A: Selection should be based on availability, lead time, and manufacturer preference. SMBJ7.5A-13-F (Diodes Incorporated) and SMBJ7.5A-E3/52 (Vishay) are both qualified equivalents with identical electrical performance within their specified operating range.
