Substitute Part Grouping Explanation

Substitution of the TPSMP33AHM3/84A is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 28.2V
• Voltage - Breakdown (Min): 31.4V
• Voltage - Clamping (Max) @ Ipp: 45.7V
• Current - Peak Pulse (10/1000µs): 8.8A
• Power - Peak Pulse: 400W
• Unidirectional Channels: 1
• Package / Case: DO-220AA (SMP)
• Operating Temperature Range: -65°C to 185°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101

The substitute part TPSMP33AHM3_A/H maintains identical electrical and mechanical specifications while differing only in packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The TPSMP33AHM3_A/H is a direct functional equivalent to the TPSMP33AHM3/84A. Both components are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical performance specifications, thermal operating range, and automotive-grade qualification (AEC-Q101).

The primary distinction between these parts is product status and packaging format. The TPSMP33AHM3/84A is classified as obsolete, while the TPSMP33AHM3_A/H maintains active product status with current manufacturing support. The TPSMP33AHM3_A/H is supplied in Tape & Reel format, which is standard for high-volume production environments.

For new designs and ongoing system support, the TPSMP33AHM3_A/H is the appropriate selection due to its active status and continued availability. Both parts satisfy identical compliance requirements including ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can TPSMP33AHM3_A/H be used as a direct replacement for TPSMP33AHM3/84A?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters including voltage ratings, current handling, temperature range, and package specifications. The substitute part maintains the same DO-220AA (SMP) surface mount package and automotive-grade qualification.

Q: What is the difference between these two part numbers?

A: The TPSMP33AHM3/84A is obsolete, while TPSMP33AHM3_A/H is active. The packaging format differs: TPSMP33AHM3/84A is supplied in bulk, while TPSMP33AHM3_A/H is supplied in Tape & Reel format. All electrical and thermal specifications are identical.

Q: Are there any compatibility concerns when substituting these parts?
