Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMAJ64CA-M3/61 are qualified based on the following critical parameters that determine functional equivalence:

• Voltage - Reverse Standoff (Typ): 64V
• Voltage - Breakdown (Min): 71.1V
• Voltage - Clamping (Max) @ Ipp: 103V
• Current - Peak Pulse (10/1000µs): 3.9A or equivalent
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Type: Zener, Bidirectional Channels: 1
• RoHS Status: ROHS3 Compliant

All identified substitute parts maintain these core electrical and mechanical specifications, ensuring direct functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring regulatory alignment and long-term availability. The SMAJ64CA (Meritek) exhibits a peak pulse current specification of 3.88A, which is marginally lower than the 3.9A specification of the primary part and other substitutes; this variance remains within typical manufacturing tolerances for this component category. The SMAJ64CA-TP (Micro Commercial Co) supports an extended operating temperature range of -55°C to 175°C (TA), providing additional thermal margin compared to the primary part's -55°C to 150°C (TJ) specification. Selection among these substitutes should be based on procurement availability, lead time requirements, and specific application thermal constraints.

Frequently Asked Questions (FAQ)

Q: Can SMAJ64CA-M3/61 be directly replaced with SMAJ64CA (Meritek)?

A: Yes. Both parts share identical voltage specifications (64V standoff, 71.1V breakdown, 103V clamping), equivalent power ratings (400W), and the same DO-214AC (SMA) package. The peak pulse current difference of 0.02A (3.9A vs 3.88A) is within acceptable manufacturing tolerance for TVS diode applications.

Q: What is the difference between SMAJ64CA-13-F and SMAJ64CA-TP?

A: Both parts are functionally equivalent to the primary SMAJ64CA-M3/61 with identical electrical specifications. The primary distinction is the operating temperature range: SMAJ64CA-13-F operates from -55°C to 150°C (TJ), while SMAJ64CA-TP extends to -55°C to 175°C (TA). Selection depends on application thermal requirements.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use the DO-214AC (SMA) surface mount package, ensuring mechanical and footprint compatibility with the original SMAJ64CA-M3/61 design.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. All listed substitute parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), matching the environmental and regulatory specifications of the primary part.

Q: Which substitute part has the widest operating temperature range?

A: The SMAJ64CA-TP (Micro Commercial Co) supports the widest operating temperature range at -55°C to 175°C (TA), compared to -55°C to 150°C for the primary part and other substitutes.
