SA6.0AG Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts
Part Overview
The SA6.0AG is a unidirectional Zener-type transient voltage suppressor diode manufactured by Littelfuse, designed for general-purpose overvoltage protection applications. Housed in a DO-204AC (DO-15) axial through-hole package, this component provides 6V reverse standoff voltage with a 10.3V maximum clamping voltage at peak pulse current of 48.5A.
The SA6.0AG is classified as obsolete. Equivalent and substitute parts are available from multiple manufacturers with active product status, offering identical or compatible electrical characteristics and the same through-hole axial package configuration.

Engineering Selection Recommendations
For Direct Replacement (10.3V Clamping Voltage):
Select from Group 1 parts when the circuit design requires the exact clamping voltage specification of 10.3V and peak pulse current of 48.5A or higher. All Group 1 substitutes are active products with ROHS3 compliance and REACH unaffected status.
- SA6.0A (Taiwan Semiconductor Corporation) offers the highest peak pulse current (50A) and extended temperature range (-55 to 175°C) in tape & reel packaging.
- SA6.0A-B (Littelfuse Inc.) provides manufacturer continuity with active status and bulk packaging.
- P5KE6.0A series (Micro Commercial Co) variants offer extended low-temperature operation (-65°C minimum) with identical electrical specifications.
For Relaxed Clamping Voltage Applications (11.2V Clamping Voltage):
Select from Group 2 parts when circuit design permits higher clamping voltage (11.2V) and reduced peak pulse current (41A). These parts maintain identical standoff and breakdown voltages while offering active product status and extended temperature ranges.
- SAC6.0-E3/54 (Vishay General Semiconductor - Diodes Division) provides TransZorb® series designation with tape & reel packaging and ROHS3 compliance.
- SAC6.0-TP (Micro Commercial Co) offers tape & reel packaging with ROHS3 compliance.
All recommended substitutes are ROHS3 compliant, REACH unaffected, and rated for general-purpose applications in DO-204AC (DO-15) axial through-hole configuration.
Frequently Asked Questions (FAQ)
Q: Can SA6.0A be used as a direct replacement for SA6.0AG?
A: Yes. SA6.0A meets all primary electrical criteria: 6V reverse standoff, 6.67V minimum breakdown, 10.3V maximum clamping voltage, and 50A peak pulse current (exceeds the 48.5A requirement). Both use DO-204AC (DO-15) axial through-hole packaging. SA6.0A is an active product with extended operating temperature range (-55 to 175°C versus -55 to 150°C).
Q: What is the difference between Group 1 and Group 2 substitutes?
A: Group 1 parts (SA6.0A, SA6.0A-B, P5KE6.0A series, SA6.0A-TP) maintain the 10.3V clamping voltage with peak pulse current of 48.5A to 50A. Group 2 parts (SAC6.0 series) have a higher clamping voltage of 11.2V with reduced peak pulse current of 41A. Selection depends on circuit tolerance for clamping voltage variation.
Q: Are all substitutes available in the same packaging?
A: All substitutes use DO-204AC (DO-15) axial through-hole package configuration. Packaging format (bulk, tape & reel) varies by manufacturer and part number suffix. Verify packaging requirements for your assembly process.
Q: What compliance certifications apply to these substitutes?
A: All listed substitutes are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (Unlimited) for parts with specified MSL ratings. ECCN classification is EAR99 for all parts.
Q: Can P5KE6.0A series parts be used in place of SA6.0AG?
A: Yes. P5KE6.0A-AP, P5KE6.0A-BP, and P5KE6.0A-TP all meet electrical specifications with 10.3V clamping voltage and 48.5A peak pulse current. These parts offer extended low-temperature operation (-65°C minimum) compared to SA6.0AG (-55°C minimum).
Q: What is the operating temperature difference between SA6.0AG and its substitutes?
A: SA6.0AG operates from -55 to 150°C. Most active substitutes extend the upper temperature limit to 175°C. P5KE6.0A series extends the lower limit to -65°C. Verify application temperature requirements before selection.
