SMBJ100CA-13 Equivalent & Substitute Parts

Part Overview

The SMBJ100CA-13 is a bidirectional 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 600W peak pulse power rating. The SMBJ100CA-13 is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ100CA-13 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 100V
• Voltage - Breakdown (Min): 111V
• Voltage - Clamping (Max) @ Ipp: 162V
• Current - Peak Pulse (10/1000µs): 3.7A (±0.1A tolerance acceptable)
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Bidirectional operation (for direct substitution)

Acceptable Variations:

• Operating temperature range may extend beyond the original specification
• Packaging format (Tape & Reel vs. Cut Tape) does not affect electrical compatibility
• RoHS compliance status may differ from the original part
• Manufacturer differences are acceptable provided electrical parameters match

The substitute parts listed below meet all critical electrical parameters and package requirements for direct substitution in the SMBJ100CA-13 application.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Recommended): SMBJ100CA-13-F (Diodes Incorporated)

This part is manufactured by the original equipment manufacturer and maintains identical electrical specifications and operating temperature range. It is ROHS3 compliant and currently in active production with high inventory availability (7,900 pcs).

Secondary Substitutes (Active Production):

SMBJ100CA (Good-Ark Semiconductor) and SMBJ100CA-TP (Micro Commercial Co) are functionally equivalent with identical electrical parameters. Both are ROHS3 compliant and available in high quantities. These parts are suitable for applications where manufacturer origin is not a critical constraint.

SMBJ100CA-TR (STMicroelectronics) is ROHS3 compliant with a marginally higher peak pulse current specification (3.8A vs. 3.7A), which provides additional design margin. Operating temperature range matches the original specification.

Limited Substitution: SMBJ100A-TP (Micro Commercial Co)

This part is unidirectional (single channel) rather than bidirectional. It is suitable only for applications where unidirectional transient suppression is acceptable. It is ROHS3 compliant with extended operating temperature range (-55°C ~ 175°C).

All substitute parts are available in active production status, ensuring long-term supply continuity compared to the discontinued SMBJ100CA-13.

Frequently Asked Questions (FAQ)

Q: Can SMBJ100CA-13-F be used as a direct replacement for SMBJ100CA-13?

A: Yes. SMBJ100CA-13-F is manufactured by Diodes Incorporated with identical electrical specifications, package type (DO-214AA SMB), and operating temperature range. The primary difference is RoHS3 compliance and active production status.

Q: What is the difference between bidirectional and unidirectional TVS diodes?

A: Bidirectional TVS diodes suppress transients in both positive and negative directions, suitable for AC or differential signal lines. Unidirectional TVS diodes suppress transients in one direction only, suitable for DC or single-polarity applications. SMBJ100A-TP is unidirectional and should only be used if your application requires single-direction protection.

Q: Are there any compatibility issues with different manufacturers?

A: No. All substitute parts listed maintain identical electrical parameters (voltage, current, power ratings) and the same DO-214AA SMB package. They are pin-compatible and functionally interchangeable in the circuit.

Q: Does the packaging format (Tape & Reel vs. Cut Tape) affect performance?

A: No. Packaging format affects only handling and assembly logistics. Electrical performance and reliability are identical regardless of packaging format.

Q: Why is the SMBJ100CA-13 discontinued?

A: The original part is discontinued at DiGi Electronics. However, equivalent parts from multiple manufacturers remain in active production, ensuring continued availability for new designs and maintenance applications.

Q: Can I use SMBJ100CA-TR if my application operates at temperatures above 150°C?

A: No. SMBJ100CA-TR has the same maximum operating temperature as the original part (-55°C ~ 150°C). For extended temperature applications, SMBJ100CA-TP or SMBJ100A-TP, which support -55°C ~ 175°C, are suitable alternatives.

Q: What does "RoHS3 Compliant" mean?

A: RoHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates the part meets EU environmental standards by restricting hazardous materials. The original SMBJ100CA-13 is RoHS non-compliant, while all active substitute parts are RoHS3 compliant, making them preferable for new designs and regulated applications.
