SMA5J9.0CA-M3/5A Equivalent & Substitute Parts

Part Overview

The SMA5J9.0CA-M3/5A is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component operates with a 9V reverse standoff voltage and provides 15.4V maximum clamping voltage at peak pulse current. The device is housed in a DO-214AC (SMA) surface mount package and is designed for general-purpose transient protection applications. The part is currently in active production status with 726 units in stock. Equivalent and substitute parts are identified based on matching electrical characteristics and package compatibility to support procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMA5J9.0CA-M3/5A is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 9V
• Voltage - Clamping (Max) @ Ipp: 15.4V
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

The SMAJ9.0CA manufactured by MDD meets these substitution criteria. Both parts share identical reverse standoff voltage, clamping voltage, package configuration, and mounting type. The substitute part maintains the same electrical protection characteristics within the specified voltage range and operates across a compatible temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both the SMA5J9.0CA-M3/5A and SMAJ9.0CA are active production components with ROHS3 compliance and identical voltage protection specifications. The primary difference is peak pulse current handling: the Vishay part supports 32.5A at 500W peak pulse power, while the MDD substitute supports 26A at 400W. Selection between these parts depends on the specific transient current requirements of the application. Both parts are suitable for general-purpose transient voltage suppression in DO-214AC surface mount applications. Compliance certifications and regulatory status are equivalent across both options.

Frequently Asked Questions (FAQ)

Q: Can SMAJ9.0CA replace SMA5J9.0CA-M3/5A in all applications?

A: Both parts share identical reverse standoff voltage (9V) and clamping voltage (15.4V) specifications. The SMAJ9.0CA is suitable for applications where peak pulse current does not exceed 26A. Applications requiring the full 32.5A peak pulse capability of the original part require the SMA5J9.0CA-M3/5A.

Q: Are the package dimensions identical between these parts?

A: Both parts use the DO-214AC (SMA) surface mount package, ensuring mechanical and electrical compatibility on PCB layouts designed for either component.

Q: What is the temperature operating range difference?

A: The SMA5J9.0CA-M3/5A operates from -55°C to 150°C, while the SMAJ9.0CA operates from -50°C to 150°C. Applications requiring operation below -50°C require the original Vishay part.

Q: Are both parts RoHS compliant?

A: Yes, both the SMA5J9.0CA-M3/5A and SMAJ9.0CA are ROHS3 compliant.

Q: What determines whether a substitute part is acceptable?

A: Substitution is valid when reverse standoff voltage, clamping voltage, package type, and mounting configuration match the original part. Peak pulse current and power ratings must meet or exceed application requirements.
