1SMB6.5A TR13 PBFREE Equivalent & Substitute Parts

Part Overview

The 1SMB6.5A TR13 PBFREE is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Central Semiconductor Corp in the DO-214AA (SMB) surface mount package. This component is designed for general-purpose transient voltage suppression applications, offering a 6.5V reverse standoff voltage with an 11.2V maximum clamping voltage and 53.6A peak pulse current capability. The part is ROHS3 compliant and carries an active product status. Equivalent and substitute parts are identified based on matching electrical characteristics and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1SMB6.5A TR13 PBFREE are qualified based on the following criteria:

• Voltage - Reverse Standoff: 6.5V (exact match)
• Voltage - Clamping (Max) @ Ipp: 11.2V (exact match)
• Package / Case: DO-214AA or SMB (mechanical compatibility)
• Type: Zener, Unidirectional (functional equivalence)
• RoHS Status: ROHS3 Compliant (regulatory compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (handling compatibility)

All identified substitute parts maintain these core electrical and mechanical parameters, ensuring direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original 1SMB6.5A TR13 PBFREE component. The SMBJ6.5A from Taiwan Semiconductor Corporation exhibits a marginally higher peak pulse current specification (56A versus 53.6A), which remains within acceptable substitution parameters for general-purpose TVS applications. The remaining substitute parts (SMBJ6.5A-13-F, SMBJ6.5A-E3/52, and SMBJ6V5A) match the original specifications across all critical electrical parameters.

Operating temperature range differences exist between the original part (-65°C ~ 150°C) and substitute parts (-55°C ~ 150°C). Applications requiring operation below -55°C must retain the original 1SMB6.5A TR13 PBFREE component.

Frequently Asked Questions (FAQ)

Q: Can SMBJ6.5A from Taiwan Semiconductor replace 1SMB6.5A TR13 PBFREE?

A: Yes. The SMBJ6.5A maintains identical voltage specifications (6.5V reverse standoff, 11.2V clamping) and package compatibility (DO-214AA, SMB). The peak pulse current specification is 56A versus 53.6A, which does not restrict substitution for general-purpose applications.

Q: What is the difference between the substitute parts?

A: All substitute parts share identical voltage and power ratings. Differences exist in manufacturer, packaging format (Tape & Reel versus Cut Tape), and operating temperature range. The original part and SMBJ6.5A-13-F support -55°C minimum operation, while SMBJ6.5A-E3/52 and SMBJ6V5A are available in Cut Tape packaging.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, matching the regulatory status of the original 1SMB6.5A TR13 PBFREE component.

Q: Does package format affect substitution?

A: No. All substitute parts use the DO-214AA (SMB) surface mount package, ensuring mechanical and electrical compatibility regardless of packaging format (Tape & Reel or Cut Tape).

Q: What is the minimum operating temperature for substitution?

A: The original 1SMB6.5A TR13 PBFREE supports -65°C minimum operation. All substitute parts support -55°C minimum operation. Applications requiring operation below -55°C must use the original component.
