1.5SMC110CA-M3/9AT Equivalent & Substitute Parts

Part Overview

The 1.5SMC110CA-M3/9AT is a bidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 94V reverse standoff voltage range with a 152V maximum clamping voltage and 1500W peak pulse power rating. The part is actively produced and ROHS3 compliant, making it suitable for general-purpose transient protection applications. Equivalent and substitute parts are identified based on matching electrical specifications and mechanical compatibility within the DO-214AB (SMC) package standard.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1.5SMC110CA-M3/9AT are qualified based on the following critical parameters that determine functional equivalence:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 94V
• Voltage - Breakdown (Min): 105V
• Voltage - Clamping (Max) @ Ipp: 152V
• Current - Peak Pulse (10/1000µs): 9.9A or higher
• Power - Peak Pulse: 1500W (1.5kW)
• Bidirectional Channels: 1
• Type: Zener

Mechanical Compatibility Criteria:

• Package / Case: DO-214AB (SMC)
• Mounting Type: Surface Mount

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Product Status: Active

Parts meeting all electrical parameters within the specified ranges and housed in the identical DO-214AB (SMC) package are classified as direct substitutes. Variations in peak pulse current above the minimum threshold (9.9A) and operating temperature ranges do not disqualify substitution when all other parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed meet the core electrical and mechanical requirements for direct substitution. Selection should be based on the following factors:

Vishay 1.5SMC110CA-M3/9AT: Primary specification with -65°C lower operating temperature limit. Suitable for applications requiring extended low-temperature performance.

Vishay 1.5SMC110CA-E3/57T: Identical electrical and thermal specifications to the main part. Packaging variant (E3/57T tape configuration) may differ from M3/9AT. Verify tape reel specifications for automated assembly compatibility.

Taiwan Semiconductor Corporation 1.5SMC110CA: Meets all core electrical parameters with marginally higher peak pulse current (10.3A vs. 9.9A). Operating temperature minimum is -55°C, which is 10°C higher than Vishay variants. ROHS3 compliant and actively produced. Suitable for applications where the higher minimum operating temperature does not present a constraint.

All parts are ROHS3 compliant and actively produced, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can 1.5SMC110CA-E3/57T be used as a direct replacement for 1.5SMC110CA-M3/9AT?

A: Yes. Both parts share identical electrical specifications (94V standoff, 105V breakdown minimum, 152V clamping maximum, 9.9A peak pulse current, 1500W power rating) and are housed in the DO-214AB (SMC) package. The suffix designations (M3/9AT vs. E3/57T) indicate different tape reel configurations. Verify that the tape specifications are compatible with your assembly equipment before implementation.

Q: Is the Taiwan Semiconductor Corporation 1.5SMC110CA a suitable substitute?

A: Yes. This part meets all critical electrical parameters and is housed in the identical DO-214AB (SMC) package. The peak pulse current is slightly higher (10.3A vs. 9.9A), which provides additional margin. The operating temperature range minimum is -55°C instead of -65°C. If your application operates above -55°C, this part is fully compatible. Confirm compliance with your system's temperature requirements before selection.

Q: What is the significance of the different tape reel suffixes (M3/9AT vs. E3/57T)?

A: These suffixes denote different tape and reel configurations used for automated component placement. Both parts are electrically identical. The suffix indicates packaging format for manufacturing purposes. Verify that the specific tape configuration is compatible with your pick-and-place equipment specifications.

Q: Are all listed parts ROHS3 compliant?

A: Yes. All three parts carry ROHS3 compliance certification, meeting regulatory requirements for restricted substances in electrical and electronic equipment.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All parts use the DO-214AB (SMC) surface mount package with identical pinout and footprint. No PCB layout modifications are required for substitution.
