Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMA6F6.0A-M3/6B is determined by the following critical parameters:

• Voltage - Reverse Standoff: Must be 6V (nominal)
• Voltage - Breakdown (Min): Must be within 6.7V range
• Voltage - Clamping (Max) @ Ipp: Must not exceed 13.7V
• Current - Peak Pulse: Must support minimum 38.8A capability
• Power - Peak Pulse: Must support minimum 400W capability
• Operating Temperature Range: Must cover -55°C to 175°C
• Mounting Type: Surface Mount required
• RoHS Status: ROHS3 Compliant required

The identified substitute part SMAJ6.0A-TP meets these substitution criteria. Both parts share the same 6V reverse standoff voltage, identical breakdown voltage specifications, and compatible operating temperature ranges. The substitute maintains surface mount configuration and RoHS3 compliance. Package differences (DO-221AC vs. DO-214AC) are noted but do not prevent functional substitution in applications where board layout permits the alternative footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the SMA6F6.0A-M3/6B and SMAJ6.0A-TP are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The SMA6F6.0A-M3/6B is recommended for applications requiring peak pulse current handling of 290A and peak pulse power dissipation of 4000W. The DO-221AC (SlimSMA) package provides a compact form factor suitable for space-constrained designs.

The SMAJ6.0A-TP substitute is suitable for applications with lower peak pulse current requirements (38.8A) and peak pulse power dissipation (400W). The DO-214AC (SMA) package offers standard footprint compatibility. The lower clamping voltage (10.3V vs. 13.7V) provides tighter voltage regulation in transient suppression circuits.

Selection between these parts should be based on specific application requirements for peak pulse current handling, power dissipation capability, and available board space for the respective package footprints.

Frequently Asked Questions (FAQ)

Q: Can SMAJ6.0A-TP be used as a direct replacement for SMA6F6.0A-M3/6B?

A: Functional substitution is possible when application requirements permit. Both parts share identical 6V reverse standoff voltage and compatible breakdown voltage specifications. However, the substitute has lower peak pulse current (38.8A vs. 290A) and peak pulse power (400W vs. 4000W) ratings. Verify that your application does not exceed the substitute's current and power specifications. Package footprints differ (DO-221AC vs. DO-214AC), requiring PCB layout verification.

Q: What are the key electrical differences between these parts?

A: The primary electrical differences are peak pulse current rating (290A vs. 38.8A) and clamping voltage (13.7V vs. 10.3V). Both maintain the same 6V reverse standoff voltage and operating temperature range. The lower clamping voltage of the substitute may provide improved transient suppression in some circuit topologies.

Q: Are both parts RoHS compliant?

A: Yes, both SMA6F6.0A-M3/6B and SMAJ6.0A-TP are ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH unaffected status.

Q: What is the difference between DO-221AC and DO-214AC packages?

A: DO-221AC (SlimSMA) and DO-214AC (SMA) are both surface mount packages for TVS diodes with different physical dimensions and footprints. DO-221AC is a slimmer variant. PCB layout and available space will determine package compatibility for your specific application.

Q: Can I use SMAJ6.0A-TP in a high-current transient suppression circuit?

A: No. The SMAJ6.0A-TP is rated for 38.8A peak pulse current, which is significantly lower than the SMA6F6.0A-M3/6B (290A). For high-current applications, use the SMA6F6.0A-M3/6B or verify that your circuit's transient current does not exceed 38.8A.
