Substitute Part Grouping Explanation

Substitute parts for the TPSMB20AHM3_A/I are identified based on strict equivalence of the following critical parameters:

• Voltage - Reverse Standoff (Typ): 17.1V
• Voltage - Breakdown (Min): 19V
• Voltage - Clamping (Max) @ Ipp: 27.7V
• Current - Peak Pulse (10/1000µs): ≥21.7A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The P6SMB20A-AU_R1_000A1 manufactured by Panjit International Inc. meets all substitution criteria with equivalent electrical performance and identical mechanical packaging specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TPSMB20AHM3_A/I and P6SMB20A-AU_R1_000A1 are active production components with automotive-grade classification and AEC-Q101 qualification. Both devices comply with ROHS3 standards and maintain MSL 1 moisture sensitivity ratings.

The primary distinction is the operating temperature range. The TPSMB20AHM3_A/I supports -65°C to 185°C (TJ), while the P6SMB20A-AU_R1_000A1 operates within -55°C to 150°C (TJ). Selection between these parts depends on the specific thermal requirements of the application. For applications operating within the -55°C to 150°C range, both parts are functionally interchangeable. For applications requiring extended low-temperature operation below -55°C or sustained junction temperatures above 150°C, the TPSMB20AHM3_A/I is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB20A-AU_R1_000A1 be used as a direct replacement for the TPSMB20AHM3_A/I?

A: Yes, provided the application operating temperature range does not exceed -55°C to 150°C (TJ). Both parts share identical electrical specifications, package geometry (DO-214AA, SMB), and automotive qualifications.

Q: What is the significance of the operating temperature range difference?

A: The TPSMB20AHM3_A/I extends to -65°C minimum and 185°C maximum junction temperature, while the P6SMB20A-AU_R1_000A1 is rated to -55°C minimum and 150°C maximum. Applications requiring operation outside the Panjit range must use the Vishay component.

Q: Are both parts suitable for automotive applications?

A: Yes. Both components carry automotive-grade classification and AEC-Q101 qualification, meeting automotive industry reliability and quality standards.

Q: Do both parts have identical mechanical packaging?

A: Yes. Both components use DO-214AA (SMB) surface mount packaging with identical footprint and land pattern compatibility.

Q: What is the peak pulse current difference between these parts?

A: The TPSMB20AHM3_A/I is rated at 21.7A peak pulse current, while the P6SMB20A-AU_R1_000A1 is rated at 22A. Both ratings exceed the minimum requirement and are functionally equivalent for circuit protection applications.

Q: Are both parts RoHS compliant?

A: Yes. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.
