SMBJ100A-13 Equivalent & Substitute Parts

Part Overview

The SMBJ100A-13 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated in the DO-214AA (SMB) surface mount package. This component is designed for general-purpose transient voltage suppression applications with a 100V reverse standoff voltage and 162V maximum clamping voltage at peak pulse current.

The SMBJ100A-13 is currently discontinued at DiGi Electronics. Equivalent substitute parts are available from alternative manufacturers and packaging configurations that maintain identical electrical specifications and mechanical compatibility, ensuring direct replacement capability in existing designs.

Substitute Part Grouping Explanation

Substitute parts for the SMBJ100A-13 are qualified based on the following electrical and mechanical parameters:

Voltage - Reverse Standoff: 100V (exact match required)
Voltage - Breakdown (Min): 111V (exact match required)
Voltage - Clamping (Max) @ Ipp: 162V (exact match required)
Current - Peak Pulse (10/1000µs): 3.7A (exact match required)
Power - Peak Pulse: 600W (exact match required)
Package / Case: DO-214AA, SMB (exact match required)
Mounting Type: Surface Mount (exact match required)
Type: Zener, Unidirectional (exact match required)

All substitute parts listed maintain these critical parameters. Variations in operating temperature range, packaging format (tape & reel vs. cut tape), and manufacturer do not affect functional equivalence for this application category.

Engineering Selection Recommendations

SMBJ100A-13-F (Diodes Incorporated) is the primary direct substitute. This part maintains identical electrical specifications and operating temperature range as the original SMBJ100A-13. The -F suffix indicates Cut Tape and Digi-Reel packaging format. Product status is Active with RoHS3 compliance.

SMBJ100A-TP (Micro Commercial Co) provides equivalent electrical performance with an extended operating temperature range (-55°C ~ 175°C). This part is supplied in Tape & Reel format and carries RoHS3 compliance. The extended temperature capability provides additional design margin for high-temperature applications.

SMBJ100A (MDD) is a manufacturer-recommended equivalent with identical electrical specifications. Operating temperature range is -50°C ~ 150°C. This part is available in high inventory volume and carries RoHS3 compliance. The -50°C lower temperature limit is suitable for most general-purpose applications.

All substitute parts are RoHS3 compliant and REACH unaffected, meeting modern regulatory requirements. Selection should be based on packaging availability, lead time, and specific temperature operating requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can SMBJ100A-13-F be used as a direct replacement for SMBJ100A-13?

A: Yes. SMBJ100A-13-F maintains identical electrical specifications (100V standoff, 111V breakdown minimum, 162V clamping maximum, 3.7A peak pulse current, 600W peak power) and operating temperature range (-55°C ~ 150°C). The difference is packaging format: -13-F uses Cut Tape and Digi-Reel, while -13 uses standard packaging. Both are DO-214AA (SMB) surface mount packages with identical footprints.

Q: What is the difference between SMBJ100A-TP and SMBJ100A-13?

A: Electrical specifications are identical. SMBJ100A-TP is manufactured by Micro Commercial Co and supplied in Tape & Reel format. The key difference is operating temperature range: SMBJ100A-TP extends to 175°C maximum junction temperature, compared to 150°C for SMBJ100A-13. Both use the same DO-214AA (SMB) package.

Q: Are all substitute parts RoHS compliant?

A: Yes. SMBJ100A-13-F, SMBJ100A-TP, and SMBJ100A (MDD) are all RoHS3 compliant. The original SMBJ100A-13 is RoHS non-compliant, making the substitutes preferable for new designs and applications requiring regulatory compliance.

Q: Can I use SMBJ100A (MDD) in applications requiring -55°C operation?

A: SMBJ100A (MDD) has a minimum operating temperature of -50°C. If your application requires operation at -55°C, use SMBJ100A-13-F or SMBJ100A-TP, both of which are rated to -55°C.

Q: Do all substitute parts use the same DO-214AA (SMB) package?

A: Yes. All substitute parts use the DO-214AA (SMB) surface mount package with identical mechanical dimensions and PCB footprint compatibility. Packaging format differences (Cut Tape, Tape & Reel) refer to supply method, not component package.
