Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPSMC8.2HE3_A/I is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 6.63V nominal
• Voltage - Clamping (Max) @ Ipp: 12.5V maximum
• Current - Peak Pulse (10/1000µs): 120A minimum
• Package / Case: DO-214AB (SMC) surface mount
• Operating Temperature Range: -65°C to 185°C (TJ)
• Grade: Automotive with AEC-Q101 qualification
• Unidirectional configuration: 1 channel

The substitute part TPSMC8.2AHE3_B/I maintains compatibility within the PAR® series, sharing the same base product number (TPSMC8.2) and package specification. Electrical parameters remain within acceptable tolerance ranges for transient suppression applications.

Parameter Comparison

Engineering Selection Recommendations

The TPSMC8.2AHE3_B/I is the designated substitute for the obsolete TPSMC8.2HE3_A/I. Both components maintain identical automotive grade qualification (AEC-Q101) and operating temperature specifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Electrical parameter variations between the two parts fall within the acceptable tolerance band for the PAR® series TVS diode family. The substitute exhibits marginally improved peak pulse current capability (124A versus 120A) and a lower clamping voltage (12.1V versus 12.5V), both of which are favorable characteristics for transient suppression applications.

Both parts are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, supporting equivalent reliability in automotive and industrial environments.

Frequently Asked Questions (FAQ)

Q: Can TPSMC8.2AHE3_B/I be used as a direct replacement for TPSMC8.2HE3_A/I?

A: Yes. Both parts share identical package specifications (DO-214AB SMC), mounting type (surface mount), operating temperature range (-65°C to 185°C TJ), and automotive qualification (AEC-Q101). Electrical parameters are within acceptable tolerance for the PAR® series.

Q: What is the primary reason for substitution?

A: The TPSMC8.2HE3_A/I is classified as Obsolete. The TPSMC8.2AHE3_B/I is an Active product from the same manufacturer and series, ensuring continued availability and manufacturing support.

Q: Are there packaging differences between these parts?

A: The main part is supplied in standard packaging, while the substitute is available in Tape & Reel (TR) format. Both use the identical DO-214AB (SMC) component package for surface mount assembly.

Q: How do the electrical parameters compare?

A: The substitute exhibits a slightly higher reverse standoff voltage (7.02V versus 6.63V) and marginally improved peak pulse current (124A versus 120A). The clamping voltage is slightly lower (12.1V versus 12.5V). These variations are within the design tolerance of the PAR® series and do not affect functional compatibility.

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 qualification standards.
