SMAJ7.5CA-TP Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The SMAJ7.5CA-TP is an active Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional Zener diode operates with a 7.5V reverse standoff voltage and provides 12.9V maximum clamping voltage at peak pulse current. The component is supplied in Tape & Reel packaging with DO-214AC (SMA) form factor. Equivalent and substitute parts are identified based on matching electrical specifications, package compatibility, and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMAJ7.5CA-TP are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 7.5V
• Voltage - Clamping (Max) @ Ipp: 12.9V
• Current - Peak Pulse (10/1000µs): 31A
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Type: Zener
• Bidirectional Channels: 1
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain these core specifications, ensuring functional equivalence in general-purpose transient voltage suppression applications. Variations in operating temperature range and packaging format (Tape & Reel versus standard packaging) do not affect electrical performance in the specified application.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance with MSL Level 1 rating. The SMAJ7.5CA-TP from Micro Commercial Co offers the widest operating temperature range (-55°C to 175°C ambient), providing extended thermal performance for demanding applications. The SMAJ7.5CA from MDD and SMAJ7.5CA-13-F from Diodes Incorporated are functionally equivalent alternatives with comparable electrical specifications and compliance certifications. Selection between these parts should be based on availability, supply chain requirements, and specific operating temperature constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can SMAJ7.5CA from MDD be used as a direct replacement for SMAJ7.5CA-TP?

A: Yes. Both parts share identical electrical specifications including 7.5V reverse standoff voltage, 12.9V clamping voltage, 31A peak pulse current, and 400W peak pulse power. Both are packaged in DO-214AC (SMA) surface-mount form factor with ROHS3 compliance and MSL Level 1 rating. The primary difference is the operating temperature range: SMAJ7.5CA-TP operates to 175°C ambient, while SMAJ7.5CA operates to 150°C junction temperature.

Q: What is the difference between SMAJ7.5CA-13-F and SMAJ7.5CA-TP?

A: Both parts are electrically equivalent with matching voltage and current specifications. SMAJ7.5CA-13-F is manufactured by Diodes Incorporated and supplied in Tape & Reel packaging, while SMAJ7.5CA-TP is from Micro Commercial Co. Operating temperature ranges differ slightly: SMAJ7.5CA-13-F operates from -55°C to 150°C (junction), and SMAJ7.5CA-TP from -55°C to 175°C (ambient).

Q: Are all substitute parts available in the same packaging format?

A: SMAJ7.5CA-TP and SMAJ7.5CA-13-F are both supplied in Tape & Reel packaging. SMAJ7.5CA from MDD does not specify packaging format in the provided data. All three parts use the DO-214AC (SMA) surface-mount package case, ensuring PCB footprint compatibility.

Q: Do these parts require different PCB layout considerations?

A: No. All substitute parts use identical DO-214AC (SMA) package geometry, requiring no changes to PCB layout, footprint, or assembly processes.

Q: Which part should be selected for high-temperature applications?

A: SMAJ7.5CA-TP from Micro Commercial Co supports the highest ambient operating temperature at 175°C, making it the preferred choice for applications requiring extended thermal performance.
