SACB6.0 Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The SACB6.0 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection in surface mount applications. The device features a 6V reverse standoff voltage with an 11.2V maximum clamping voltage and 41A peak pulse current capability in the DO-214AA (SMB) package. The SACB6.0 maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for continuous procurement and integration into new designs.

Equivalent and substitute parts are identified based on matching electrical performance parameters within the TVS diode category, specifically maintaining compatibility across reverse standoff voltage, clamping voltage range, peak pulse current ratings, and surface mount SMB packaging requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SACB6.0 are qualified based on the following electrical and mechanical compatibility criteria:

Primary Matching Parameters:

• Reverse standoff voltage: 6V (nominal)
• Package type: DO-214AA, SMB surface mount
• Unidirectional Zener diode configuration
• General-purpose TVS application category

Acceptable Variation Range:

• Voltage - Breakdown (Min): 6.67V to 7.9V
• Voltage - Clamping (Max) @ Ipp: 10.3V to 11.2V
• Current - Peak Pulse (10/1000µs): 41A minimum
• Power - Peak Pulse: 500W minimum
• Operating temperature range: -55°C minimum to 150°C maximum

The SMBJ6.0A from EVVO Semi qualifies as a direct substitute, maintaining the 6V reverse standoff voltage specification, SMB package format, and general-purpose TVS classification while meeting or exceeding the electrical performance envelope of the SACB6.0.

Parameter Comparison

Engineering Selection Recommendations

Both the SACB6.0 and SMBJ6.0A maintain active product status with full RoHS3 compliance and REACH unaffected classification, supporting long-term design continuity and regulatory compliance requirements.

The SMBJ6.0A demonstrates enhanced electrical performance characteristics, including lower minimum breakdown voltage (6.67V vs. 7.9V), reduced maximum clamping voltage (10.3V vs. 11.2V), and higher peak pulse current capacity (58.3A vs. 41A) and power dissipation (600W vs. 500W). These parameters indicate improved transient suppression efficiency within the 6V protection class.

The SMBJ6.0A extends the operating temperature range to -65°C minimum, providing broader environmental compatibility compared to the SACB6.0 specification of -55°C minimum.

Both devices utilize identical DO-214AA SMB surface mount packaging, ensuring mechanical and thermal compatibility in existing PCB layouts without design modification.

Frequently Asked Questions (FAQ)

Q: Can SMBJ6.0A replace SACB6.0 in existing designs?

A: Yes. Both devices share identical reverse standoff voltage (6V), package format (DO-214AA, SMB), and unidirectional Zener configuration. The SMBJ6.0A meets or exceeds all electrical performance parameters of the SACB6.0, including peak pulse current and power dissipation ratings. No circuit redesign is required.

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

A: The SMBJ6.0A features lower breakdown voltage (6.67V minimum vs. 7.9V), lower clamping voltage (10.3V maximum vs. 11.2V), and higher peak pulse current capacity (58.3A vs. 41A). These differences indicate improved transient suppression performance within the same 6V protection class.

Q: Are both parts RoHS compliant?

A: Yes. Both SACB6.0 and SMBJ6.0A are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), meeting current regulatory requirements for electronic component procurement.

Q: Do these parts require different PCB footprints?

A: No. Both devices use the DO-214AA (SMB) package format, which defines identical PCB land patterns, solder pad dimensions, and thermal characteristics. Direct footprint compatibility is maintained.

Q: What is the temperature operating range difference?

A: SACB6.0 operates from -55°C to 150°C junction temperature, while SMBJ6.0A extends the lower limit to -65°C. Both maintain the same 150°C maximum junction temperature. The SMBJ6.0A provides broader low-temperature environmental coverage.
