Substitute Part Grouping Explanation

Substitution of the SPHV36-01KTG-C is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters (Non-Negotiable):

• Reverse standoff voltage: 36V (Max)
• Breakdown voltage: 40V (Min)
• Clamping voltage: 65V (Max) @ Ipp
• Peak pulse current: 2A (8/20µs)
• Peak pulse power: 200W
• Capacitance: 13pF @ 1MHz
• Operating temperature range: -40°C ~ 125°C

Mechanical & Packaging Parameters (Non-Negotiable):

• Package type: SOD-882
• Mounting type: Surface Mount
• Bidirectional channels: 1
• Diode type: Zener

Compliance & Certification (Non-Negotiable):

• Automotive grade
• AEC-Q101 qualification
• ROHS3 compliance
• MSL rating: 1 (Unlimited)

The SPHV36-01ETG-C qualifies as a direct substitute because it maintains all electrical specifications, mechanical packaging, and automotive certifications while offering the advantage of active product status and significantly higher inventory availability.
