SMBJ13CA-13 Equivalent & Substitute Parts

Part Overview

The SMBJ13CA-13 is a Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose transient voltage protection in surface mount applications. This part operates with a 13V reverse standoff voltage and provides 21.5V maximum clamping voltage at peak pulse current of 27.9A. The SMBJ13CA-13 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ13CA-13 are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff: 13V (exact match required)
• Voltage - Breakdown (Min): 14.4V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 21.5V (exact match required)
• Current - Peak Pulse (10/1000µs): 27.9A minimum (28A acceptable within tolerance)
• Power - Peak Pulse: 600W (exact match required)
• Package / Case: DO-214AA, SMB (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Zener, Bidirectional (exact match required)

Parts meeting these criteria are electrically and mechanically interchangeable for the SMBJ13CA-13 application.

Parameter Comparison

Engineering Selection Recommendations

SMBJ13CA-13-F (Diodes Incorporated) is the primary substitute. This part maintains identical electrical specifications to the original SMBJ13CA-13 and is manufactured by the same supplier. The primary difference is packaging format (Tape & Reel) and active product status. SMBJ13CA-13-F carries ROHS3 compliance, addressing regulatory requirements where the original part does not.

SMBJ13CA-TP (Micro Commercial Co) provides equivalent electrical performance with extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 150°C). This part is suitable for applications requiring higher temperature operation. ROHS3 compliance is confirmed.

SMBJ13CA (MDD) offers equivalent electrical performance with peak pulse current specified at 28A, which falls within acceptable tolerance of the 27.9A specification. Operating temperature range is -50°C ~ 150°C. ROHS3 compliance is confirmed. This part is available in high inventory volume.

All three substitute parts are active products with confirmed availability and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can SMBJ13CA-13-F directly replace SMBJ13CA-13 in existing designs?

A: Yes. SMBJ13CA-13-F maintains identical electrical specifications (13V standoff, 21.5V clamping, 27.9A peak pulse current, 600W peak power) and package format (DO-214AA, SMB). The primary difference is packaging configuration (Tape & Reel versus bulk) and active product status.

Q: What is the difference between SMBJ13CA-13-F and SMBJ13CA-TP?

A: Both parts meet the core electrical requirements. SMBJ13CA-TP offers extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 150°C) and is manufactured by Micro Commercial Co rather than Diodes Incorporated. Selection depends on application temperature requirements and supplier preference.

Q: Is the 28A peak pulse current specification of SMBJ13CA (MDD) compatible with the 27.9A requirement?

A: Yes. The 28A specification is within acceptable tolerance of the 27.9A requirement and meets the electrical protection requirements of the application.

Q: Are all substitute parts RoHS compliant?

A: SMBJ13CA-13-F, SMBJ13CA-TP, and SMBJ13CA (MDD) are all ROHS3 compliant. The original SMBJ13CA-13 is RoHS non-compliant.

Q: What packaging formats are available for these substitute parts?

A: SMBJ13CA-13-F is supplied in Tape & Reel format. SMBJ13CA-TP is supplied in Tape & Reel format. SMBJ13CA (MDD) packaging format is not specified in available data but maintains DO-214AA, SMB package compatibility.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts use identical DO-214AA, SMB surface mount package format and maintain the same pin configuration and footprint compatibility.
