SMAJ9.0A-13 Equivalent & Substitute Parts

Part Overview

The SMAJ9.0A-13 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated in a surface mount SMA package (DO-214AC). This component is designed for general-purpose transient voltage suppression applications with a 9V reverse standoff voltage and 15.4V maximum clamping voltage at peak pulse current.

The SMAJ9.0A-13 is currently discontinued at DiGi Electronics. Equivalent substitute parts are available from multiple manufacturers with identical electrical specifications and package configurations, ensuring direct functional replacement in existing designs.

Engineering Selection Recommendations

SMAJ9.0A-13-F is the primary direct substitute. Manufactured by Diodes Incorporated with identical electrical specifications, this part is in active production status with ROHS3 compliance. Tape & Reel packaging provides improved handling for automated assembly processes compared to bulk packaging of the original part.

SMAJ9.0A-E3/61 (Vishay General Semiconductor) and SMAJ9.0A-TP (Micro Commercial Co) are functionally equivalent alternatives. Both maintain all critical electrical parameters and offer ROHS3 compliance with active product status. The Vishay part is branded under the TransZorb® series designation. The Micro Commercial Co variant supports an extended operating temperature range to 175°C, suitable for applications requiring higher thermal performance.

SMAJ9.0A (MDD) is available as a manufacturer-recommended substitute with active status and ROHS3 compliance. Operating temperature range extends to -50°C minimum, which is 5°C higher than the original specification.

All substitute parts are compatible with existing PCB layouts and assembly processes due to identical DO-214AC SMA package geometry and surface mount mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can SMAJ9.0A-13-F be used as a direct replacement for SMAJ9.0A-13?

A: Yes. Both parts share identical electrical specifications including 9V reverse standoff voltage, 15.4V clamping voltage, and 26A peak pulse current. The primary difference is packaging format (Tape & Reel versus bulk) and product status (active versus discontinued). No circuit modifications are required.

Q: What is the difference between the Diodes Incorporated and Vishay versions?

A: Electrical specifications are identical. The Vishay SMAJ9.0A-E3/61 is marketed under the TransZorb® product line. Both are ROHS3 compliant with active production status. Selection between these parts is based on supplier availability and procurement preferences.

Q: Does the extended temperature range of SMAJ9.0A-TP affect compatibility?

A: No. The SMAJ9.0A-TP supports -55°C to 175°C operating range, which encompasses the original -55°C to 150°C specification. This part is suitable for applications requiring higher thermal performance without any functional compromise.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All active substitute parts listed are supplied in Tape & Reel (TR) packaging, which is standard for automated assembly processes. The original SMAJ9.0A-13 was supplied in bulk packaging.

Q: What compliance certifications apply to these substitute parts?

A: All active substitute parts are ROHS3 compliant and REACH unaffected. The original SMAJ9.0A-13 is RoHS non-compliant. For applications requiring RoHS compliance, any of the listed active substitutes are appropriate selections.

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

A: Yes. All substitute parts maintain the DO-214AC SMA package geometry, surface mount mounting type, and identical electrical performance parameters. PCB layout and assembly processes require no modification.
