Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMAJ6.0CE3/TR13 are qualified based on the following electrical and mechanical criteria:

Primary Matching Criteria:

• Reverse standoff voltage: 6V (typical)
• Breakdown voltage minimum: 6.67V or 6.7V
• Package type: DO-214AC / SMA (surface mount)
• Bidirectional configuration: Single channel
• Type: Zener diode
• RoHS3 compliance
• MSL rating: 1 (unlimited)

Acceptable Parameter Variations:

• Clamping voltage (Max @ Ipp): 10.3V to 13.7V
• Peak pulse current (10/1000µs or 8/20µs): 38.8A to 290A
• Peak pulse power: 400W to 600W
• Operating temperature range: -55°C to 175°C (minimum -55°C, maximum 150°C or higher)

Substitute parts maintain compatibility with the original design through matching voltage ratings and package specifications. Variations in clamping voltage and current ratings reflect different manufacturer implementations of the same 6V protection class, all suitable for general-purpose transient suppression applications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full ROHS3 compliance with unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original SMAJ6.0CE3/TR13.

Clamping Voltage Considerations:

Parts with 10.3V clamping (SMAJ6.0CA, SMAJ6.0CA-13-F, SMAJ6.0CA-TP) provide lower clamping voltage compared to the original 11.4V specification. These parts are suitable for applications where lower transient voltage peaks are acceptable or beneficial.

Parts with 13.7V clamping (SMA6J6.0CA-TR, SMAJ6.0CA-TR from STMicroelectronics) provide higher clamping voltage. These are appropriate for applications requiring higher transient tolerance or where the original 11.4V specification is not critical.

Peak Pulse Current and Power Ratings:

The original part specifies 43.9A at 500W. Substitute parts range from 38.8A at 400W to 290A at 600W. Selection depends on the specific transient energy profile of the application. Parts rated at 38.8A/400W are suitable for lower-energy transient environments. Parts rated at 170A or 290A provide enhanced transient suppression capability for higher-energy surge conditions.

Temperature Range:

The original part operates from -65°C to 150°C. Most substitutes operate from -55°C to 150°C or -55°C to 175°C. Applications requiring operation below -55°C must retain the original SMAJ6.0CE3/TR13. All other applications are compatible with substitute parts.

Packaging and Availability:

All substitute parts are packaged in DO-214AC (SMA) surface-mount format, ensuring mechanical and electrical compatibility. Inventory levels vary significantly across manufacturers, with Good-Ark SMAJ6.0CA offering the highest availability at 55,400 pieces.

Frequently Asked Questions (FAQ)

Q: Can I substitute SMAJ6.0CA (Good-Ark) for SMAJ6.0CE3/TR13 (Microchip)?

A: Yes. Both parts share identical reverse standoff voltage (6V), breakdown voltage (6.67V), and package format (DO-214AC/SMA). The SMAJ6.0CA has a lower clamping voltage (10.3V vs 11.4V) and lower peak pulse rating (38.8A/400W vs 43.9A/500W). This substitution is valid for applications where the lower clamping voltage and power rating are acceptable.

Q: What is the difference between the two STMicroelectronics parts (SMA6J6.0CA-TR and SMAJ6.0CA-TR)?

A: Both are STMicroelectronics TVS diodes with 6V standoff voltage and 13.7V clamping. The primary difference is peak pulse current rating: SMA6J6.0CA-TR is rated at 290A (8/20µs) with 600W power, while SMAJ6.0CA-TR is rated at 170A (8/20µs) with 400W power. The SMA6J6.0CA-TR provides higher transient suppression capability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant with MSL rating 1 (unlimited) and REACH unaffected status, matching the original part's regulatory compliance.

Q: Which substitute part has the closest electrical match to the original SMAJ6.0CE3/TR13?

A: The SMAJ6.0CA-TR from STMicroelectronics provides the closest match in clamping voltage (13.7V vs 11.4V) and operates within the same temperature range (-55°C to 150°C). However, it uses an 8/20µs pulse profile rather than the original 10/1000µs specification.

Q: Can I use a substitute part with lower clamping voltage (10.3V) in place of the original (11.4V)?

A: Yes, if the application circuit design permits. Lower clamping voltage provides more aggressive transient suppression, which is generally beneficial. However, verify that the protected circuit components can tolerate the lower peak voltage. The 10.3V clamping parts (SMAJ6.0CA, SMAJ6.0CA-13-F, SMAJ6.0CA-TP) are suitable for most general-purpose applications.

Q: What is the impact of using a substitute part with higher peak pulse current rating?

A: Higher peak pulse current ratings (170A or 290A vs 43.9A) indicate enhanced capability to suppress larger transient events without degradation. These parts are backward compatible with applications designed for lower current ratings and provide additional margin for transient protection.

Q: Are there temperature range limitations I should consider?

A: The original SMAJ6.0CE3/TR13 operates from -65°C to 150°C. Most substitutes operate from -55°C minimum. If your application requires operation below -55°C, the original part must be retained. For all other temperature ranges, substitute parts are compatible.

Q: Do all parts use the same pulse test profile?

A: No. The original part uses 10/1000µs pulse profile. STMicroelectronics parts use 8/20µs profile. Good-Ark and Diodes Incorporated parts use 10/1000µs. The pulse profile affects how peak current is measured but does not prevent substitution, as both profiles characterize the same transient suppression function.

Q: Which substitute offers the best inventory availability?

A: Good-Ark Semiconductor SMAJ6.0CA offers the highest inventory at 55,400 pieces. This part is suitable for high-volume production requirements and provides the lowest clamping voltage (10.3V) among available substitutes.
