• Electrical classification: Unidirectional Zener TVS diode with single channel
• Voltage rating range: Reverse standoff voltage between 12.9V and 13.6V; clamping voltage between 22.5V and 23.5V
• Current handling: Peak pulse current of 17A to 17.8A at 10/1000µs pulse width
• Power dissipation: 400W peak pulse power rating
• Temperature range: -65°C to 185°C junction temperature
• Automotive compliance: AEC-Q101 qualification and automotive grade designation
• Regulatory compliance: ROHS3 compliant, REACH unaffected

The substitute part TPSMP16AHM3_A/H meets all substitution criteria within the allowed parameter tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

The TPSMP16AHM3_A/H is the qualified substitute for the obsolete TPSMP16HM3/84A. Both components share identical automotive-grade classification and AEC-Q101 qualification, ensuring compliance with automotive reliability standards. The substitute maintains the same operating temperature range, power dissipation capability, and surface mount package configuration.

The TPSMP16AHM3_A/H is currently in active production status with substantial inventory availability (26,335 pieces), whereas the original part is obsolete. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The electrical parameter variations between the two parts fall within acceptable substitution tolerances for TVS diode applications in this voltage and current class.

Frequently Asked Questions (FAQ)

Q: Can TPSMP16AHM3_A/H be used as a direct replacement for TPSMP16HM3/84A?
