SA6.0ARL Equivalent & Substitute Parts

Part Overview

The SA6.0ARL is a transient voltage suppressor (TVS) diode manufactured by onsemi, designed for general-purpose overvoltage protection applications. This axial-lead through-hole component features a 6V reverse standoff voltage and 10.3V maximum clamping voltage with 48.5A peak pulse current capability. The SA6.0ARL is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Active alternatives from multiple manufacturers provide compatible electrical and mechanical specifications while offering current product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SA6.0ARL are qualified based on the following critical parameters that must remain constant across all alternatives:

• Voltage - Reverse Standoff: 6V
• Voltage - Clamping (Max) @ Ipp: 10.3V
• Type: Zener, Unidirectional
• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial
• Power - Peak Pulse: 500W
• Applications: General Purpose

The substitute parts identified maintain these core electrical specifications while offering variations in peak pulse current (within acceptable tolerance), operating temperature range, and product status. All substitutes are compatible with the original SA6.0ARL footprint and electrical function.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain electrical equivalence to the SA6.0ARL across the critical voltage and current parameters. Selection among substitutes should be based on the following factors:

SA6.0A (Taiwan Semiconductor Corporation): Active product status with ROHS3 compliance. Peak pulse current rated at 50A, providing 3.1% margin above the original specification. Extended operating temperature range to 175°C. Supplied in Tape & Reel packaging with 60,100 units in stock.

P5KE6.0A-AP (Micro Commercial Co): Active product status with extended operating temperature range (-65°C to 175°C). Peak pulse current matches original specification at 48.5A. Supplied in bulk packaging with 799 units in stock. RoHS compliance status not specified in available data.

SA6.0A-B (Littelfuse Inc.): Active product status with ROHS3 compliance. Peak pulse current rated at 49.5A, providing 2.1% margin above original specification. Extended operating temperature range to 175°C. Supplied in bulk packaging with 1,029 units in stock.

SA6.0A-TP (Micro Commercial Co): Active product status with ROHS3 compliance. Peak pulse current rated at 49.5A. Extended operating temperature range to 175°C. Supplied in Tape & Reel packaging with 834 units in stock.

For applications requiring regulatory compliance, SA6.0A, SA6.0A-B, and SA6.0A-TP all provide ROHS3 certification. For applications with elevated temperature requirements beyond 150°C, all four substitutes support operation to 175°C.

Frequently Asked Questions (FAQ)

Q: Can SA6.0A replace SA6.0ARL directly in existing designs?

A: Yes. The SA6.0A maintains identical voltage specifications (6V reverse standoff, 10.3V clamping) and package configuration (DO-204AC/DO-15 axial). The 50A peak pulse current rating exceeds the original 48.5A specification, providing additional margin. Direct substitution is electrically compatible.

Q: What is the difference between Tape & Reel and Bulk packaging options?

A: Tape & Reel packaging (SA6.0A, SA6.0A-TP) is suitable for automated assembly processes. Bulk packaging (P5KE6.0A-AP, SA6.0A-B) is typically used for manual assembly or lower-volume applications. The electrical specifications remain identical regardless of packaging format.

Q: Why does the SA6.0ARL show as obsolete?

A: The SA6.0ARL is no longer in active production by onsemi. The substitute parts listed represent current production alternatives from active manufacturers that provide equivalent electrical performance and improved compliance certifications.

Q: Are all substitutes RoHS compliant?

A: SA6.0A, SA6.0A-B, and SA6.0A-TP are ROHS3 compliant. RoHS compliance status for P5KE6.0A-AP is not specified in available documentation.

Q: What is the significance of the operating temperature range difference?

A: The SA6.0ARL operates from -55°C to 150°C. All substitute parts extend the upper limit to 175°C, providing additional thermal margin. P5KE6.0A-AP extends the lower limit to -65°C. These extended ranges do not affect substitution compatibility; they represent improved capability.

Q: Can I use P5KE6.0A-AP as a substitute if the original design specifies SA6.0ARL?

A: Yes. The P5KE6.0A-AP maintains all critical electrical parameters (6V standoff, 10.3V clamping, 48.5A peak pulse) and identical package configuration. The part number prefix differs due to manufacturer designation, but functional equivalence is maintained.
