SMAJ7.0A-TP Equivalent & Substitute Parts

Part Overview

The SMAJ7.0A-TP is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage protection in surface mount applications. This component features a 7V reverse standoff voltage with a 12V maximum clamping voltage and 33.3A peak pulse current capability in a DO-214AC (SMA) package. The part is Active status and ROHS3 compliant, making it suitable for modern electronic designs requiring transient suppression without power line protection requirements. Equivalent substitute parts are identified based on matching electrical performance parameters and package compatibility to support procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the SMAJ7.0A-TP are qualified based on strict electrical and mechanical parameter matching within the Transient Voltage Suppressors (TVS) category. The substitution criteria are:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 7V
• Voltage - Breakdown (Min): 7.78V
• Voltage - Clamping (Max) @ Ipp: 12V
• Current - Peak Pulse (10/1000µs): 33.3A
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Type: Zener
• Unidirectional Channels: 1

The P4SMAJ7.0A_R1_00001 manufactured by Panjit International Inc. meets all critical electrical parameters and package requirements, qualifying it as a direct electrical equivalent. Packaging format differences (Cut Tape vs. Tape & Reel) do not affect electrical compatibility and represent procurement and handling variations only.

Parameter Comparison

Engineering Selection Recommendations

Both the SMAJ7.0A-TP and P4SMAJ7.0A_R1_00001 are Active status components with identical electrical specifications and package configurations. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

The primary distinction is the operating temperature range specification: the SMAJ7.0A-TP is rated to 175°C (TA), while the P4SMAJ7.0A_R1_00001 is rated to 150°C (TJ). Component selection should be based on the specific thermal environment of the application. For applications operating within -55°C to 150°C, either part is suitable. For applications requiring operation above 150°C, the SMAJ7.0A-TP is the appropriate selection.

Packaging format (Cut Tape vs. Tape & Reel) is a procurement and logistics consideration and does not affect electrical performance or circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can P4SMAJ7.0A_R1_00001 be used as a direct replacement for SMAJ7.0A-TP in all applications?

A: Yes, for applications operating within the -55°C to 150°C temperature range. Both parts have identical electrical specifications (7V standoff, 12V clamping, 33.3A peak pulse current) and the same DO-214AC (SMA) package. If your application requires operation above 150°C, use the SMAJ7.0A-TP.

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

A: Cut Tape (CT) and Tape & Reel (TR) are packaging and delivery formats only. Both contain the same component in the same DO-214AC (SMA) package. Cut Tape is typically used for smaller quantities or manual assembly, while Tape & Reel is standard for automated pick-and-place assembly. Electrical performance is identical.

Q: Are both parts suitable for general-purpose transient voltage suppression?

A: Yes. Both the SMAJ7.0A-TP and P4SMAJ7.0A_R1_00001 are specified for general-purpose applications and provide identical transient suppression performance with 33.3A peak pulse current handling and 400W peak pulse power dissipation.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component use.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
