Substitute Part Grouping Explanation

Substitution eligibility for TVS diodes is determined by strict equivalence across electrical performance parameters and mechanical compatibility. The following criteria establish valid substitution:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 10V
• Voltage - Breakdown (Min): 11.1V
• Voltage - Clamping (Max) @ Ipp: 17V
• Current - Peak Pulse (10/1000µs): 88.2A
• Power - Peak Pulse: 1500W
• Unidirectional Channels: 1
• Type: Zener

Mechanical Parameters (Must Match):

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount

Compliance & Qualification (Must Match or Exceed):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

The SMCJ10AHM3_A/H meets all substitution criteria as a direct equivalent part from the same manufacturer and series.

Parameter Comparison

Engineering Selection Recommendations

The SMCJ10AHM3_A/H is a direct functional equivalent to the SMCJ10AHM3/H. Both parts are manufactured by Vishay General Semiconductor - Diodes Division within the TransZorb® series and share identical electrical specifications and automotive-grade AEC-Q101 qualification.

The primary distinction is product status and packaging format. The SMCJ10AHM3/H is discontinued at DiGi Electronics, while the SMCJ10AHM3_A/H maintains active status with current inventory availability. The substitute part is supplied in Tape & Reel (TR) packaging, which is standard for high-volume production environments and offers equivalent component performance.

Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and long-term storage without degradation.

Frequently Asked Questions (FAQ)

Q: Can SMCJ10AHM3_A/H be used as a direct replacement for SMCJ10AHM3/H?

A: Yes. Both parts are identical in electrical performance, mechanical package, and automotive qualification. The substitute part is functionally equivalent for all circuit applications requiring 10V reverse standoff TVS protection with 17V clamping voltage and 88.2A peak pulse current capability.

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

A: The primary difference is product status and packaging format. SMCJ10AHM3/H is discontinued, while SMCJ10AHM3_A/H is active. The substitute is supplied in Tape & Reel (TR) packaging versus standard packaging for the original part. Electrical and mechanical specifications are identical.
