Substitute Part Grouping Explanation

Substitution of the TPSMC24HE3_A/I is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 20.5V
• Voltage - Breakdown (Min): 22.8V
• Voltage - Clamping (Max) @ Ipp: 33.2V
• Current - Peak Pulse (10/1000µs): 45.2A
• Power - Peak Pulse: 1500W
• Unidirectional Channels: 1
• Package / Case: DO-214AB, SMC
• Operating Temperature Range: -65°C to 185°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101

The TPSMC24AHE3_B/I meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The TPSMC24AHE3_B/I is the direct equivalent for the obsolete TPSMC24HE3_A/I. Both components share identical electrical specifications, automotive-grade qualification (AEC-Q101), and ROHS3 compliance. The primary distinction is product status: the TPSMC24AHE3_B/I is active and available in Tape & Reel packaging, ensuring long-term procurement viability and supply chain continuity. For new designs or ongoing production requiring transient voltage suppression at 20.5V standoff with 45.2A peak pulse capability, the TPSMC24AHE3_B/I is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can TPSMC24AHE3_B/I be used as a direct replacement for TPSMC24HE3_A/I?
