SA6.0-B Equivalent & Substitute Parts

Part Overview

The SA6.0-B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for telecom applications. This component features a 6V reverse standoff voltage with a 10.3V maximum clamping voltage and 49.5A peak pulse current rating in a through-hole DO-204AC (DO-15) package. The SA6.0-B is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure ongoing component availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA6.0-B is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 6V
• Voltage - Breakdown (Min): 6.67V
• Voltage - Clamping (Max) @ Ipp: 10.3V
• Power - Peak Pulse: 500W

Mechanical Equivalence Criteria:

• Package / Case: DO-204AC (DO-15)
• Mounting Type: Through Hole
• Unidirectional Channels: 1

Functional Equivalence Criteria:

• Type: Zener
• Series: SA

The substitute parts SA6.0A and SA6.0A-B meet all electrical and mechanical requirements for direct substitution. Both parts maintain identical voltage specifications and package configuration. The SA6.0A exhibits a peak pulse current of 50A, which exceeds the SA6.0-B specification of 49.5A, providing equivalent or superior performance within the same thermal and electrical envelope. Both substitute parts are classified as active products with current manufacturing status, ensuring long-term availability.

Parameter Comparison

Engineering Selection Recommendations

SA6.0A (Taiwan Semiconductor Corporation)

The SA6.0A is an active product with current manufacturing status and ROHS3 compliance. This part provides a peak pulse current rating of 50A, which exceeds the SA6.0-B specification by 0.5A. The operating temperature range is -55°C to 175°C, which is narrower than the SA6.0-B range of -65°C to 175°C by 10°C at the lower limit. Selection of the SA6.0A is appropriate for applications where the minimum operating temperature does not fall below -55°C. This part is supplied in Tape & Reel packaging, suitable for automated assembly processes.

SA6.0A-B (Littelfuse Inc.)

The SA6.0A-B is an active product manufactured by Littelfuse Inc., the original manufacturer of the SA6.0-B. This part maintains identical electrical specifications to the SA6.0-B, including the 49.5A peak pulse current rating and 500W power dissipation. The operating temperature range is -55°C to 175°C. The SA6.0A-B carries ROHS3 compliance and is supplied in Bulk packaging. Selection of the SA6.0A-B is appropriate for applications requiring continuity with the original manufacturer and for environments where the minimum operating temperature does not fall below -55°C.

Both substitute parts are electrically and mechanically equivalent to the SA6.0-B and are suitable for direct replacement in new designs and field service applications.

Frequently Asked Questions (FAQ)

Q: Can the SA6.0A or SA6.0A-B be used as direct replacements for the SA6.0-B?

A: Yes. Both substitute parts maintain identical voltage specifications (6V reverse standoff, 6.67V breakdown minimum, 10.3V clamping maximum) and package configuration (DO-204AC through-hole). The electrical and mechanical parameters are equivalent, enabling direct substitution in circuit designs.

Q: What is the difference between the SA6.0A and SA6.0A-B?

A: The SA6.0A is manufactured by Taiwan Semiconductor Corporation and supplied in Tape & Reel packaging with a peak pulse current of 50A. The SA6.0A-B is manufactured by Littelfuse Inc. and supplied in Bulk packaging with a peak pulse current of 49.5A. Both parts are electrically equivalent and suitable for substitution. The choice between them depends on packaging requirements and manufacturing preferences.

Q: Are there temperature range differences between the SA6.0-B and the substitute parts?

A: Yes. The SA6.0-B operates from -65°C to 175°C, while both SA6.0A and SA6.0A-B operate from -55°C to 175°C. The substitute parts have a 10°C higher minimum operating temperature. Applications requiring operation below -55°C must retain the SA6.0-B or identify alternative components with extended low-temperature ratings.

Q: What packaging options are available for the substitute parts?

A: The SA6.0A is supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly. The SA6.0A-B is supplied in Bulk packaging. Both are through-hole components in the DO-204AC (DO-15) axial package format.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both SA6.0A and SA6.0A-B are ROHS3 compliant. The original SA6.0-B is RoHS compliant. All three parts meet RoHS environmental standards.

Q: What is the inventory status of these parts?

A: The SA6.0-B (obsolete) has 759 pieces in stock. The SA6.0A has 60,100 pieces in stock. The SA6.0A-B has 1,029 pieces in stock. The substitute parts offer significantly higher availability for ongoing production requirements.
