SMAJ5.0CA-13 Equivalent & Substitute Parts

Part Overview

The SMAJ5.0CA-13 is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface-mount applications. This part features a 5V reverse standoff voltage with a 9.2V maximum clamping voltage and 44.6A peak pulse current capability in a DO-214AC (SMA) package. The SMAJ5.0CA-13 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMAJ5.0CA-13 are classified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

• Voltage - Reverse Standoff: 5V (exact match required)
• Voltage - Breakdown (Min): 6.4V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 9.2V (exact match required)
• Current - Peak Pulse: 44.6A (exact match required)
• Power - Peak Pulse: 400W (exact match required)
• Package / Case: DO-214AC, SMA (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Zener, Bidirectional (exact match required)

Parts meeting all electrical parameters with identical packaging are classified as direct equivalents. Parts with identical electrical specifications but different packaging configurations or manufacturer sourcing are listed as alternative sources. Parts with deviations in electrical parameters are excluded from substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct electrical and mechanical equivalence to the SMAJ5.0CA-13, the following parts are suitable substitutes:

Primary Equivalents (Identical Electrical Parameters, Active Status):

• SMAJ5.0CA-13-F (Diodes Incorporated): Direct equivalent with active product status and ROHS3 compliance. Packaging available in Cut Tape and Digi-Reel formats.
• SMAJ5.0CA-E3/61 (Vishay General Semiconductor - Diodes Division): Direct equivalent with active product status and ROHS3 compliance. Marketed under the TransZorb® series.
• SMAJ5.0CA (MDD): Direct equivalent with active product status and ROHS3 compliance. Manufacturer-recommended alternative source.
• SMAJ5.0CA-TP (Micro Commercial Co): Direct equivalent with active product status and ROHS3 compliance. Available in Tape & Reel packaging.

Non-Equivalent Alternative (Parameter Deviation):

• SMAJ5.0CA-TR (STMicroelectronics): Deviates from electrical specifications with 13.4V maximum clamping voltage and 174A peak pulse current (8/20µs pulse definition). Not suitable for direct substitution where 9.2V clamping and 44.6A (10/1000µs) specifications are required.

Selection should prioritize parts with active product status and ROHS3 compliance to ensure long-term availability and regulatory alignment. Packaging format (Cut Tape, Digi-Reel, or Tape & Reel) should be selected based on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can SMAJ5.0CA-TR be used as a substitute for SMAJ5.0CA-13? A: No. While SMAJ5.0CA-TR shares the same reverse standoff voltage (5V) and package (DO-214AC, SMA), it has different clamping voltage (13.4V vs. 9.2V) and peak pulse current (174A at 8/20µs vs. 44.6A at 10/1000µs). These electrical differences make it unsuitable for direct substitution.

Q: What is the difference between SMAJ5.0CA-13-F and SMAJ5.0CA (MDD)? A: Both are direct electrical equivalents with identical voltage and current ratings. The primary differences are manufacturer (Diodes Incorporated vs. MDD) and packaging options. SMAJ5.0CA-13-F is available in Cut Tape and Digi-Reel formats, while SMAJ5.0CA (MDD) packaging details are not specified. Selection should be based on procurement availability and packaging requirements.

Q: Is the SMAJ5.0CA-13 RoHS compliant? A: No. The SMAJ5.0CA-13 is RoHS non-compliant. All active substitute parts listed (SMAJ5.0CA-13-F, SMAJ5.0CA-E3/61, SMAJ5.0CA, and SMAJ5.0CA-TP) are ROHS3 compliant, making them suitable for applications with RoHS regulatory requirements.

Q: Can I use different packaging formats interchangeably? A: All substitute parts use the DO-214AC (SMA) package, ensuring mechanical compatibility with existing PCB layouts and assembly equipment. Packaging format variations (Cut Tape, Digi-Reel, Tape & Reel) affect procurement and handling but do not impact electrical performance or board-level compatibility.

Q: Why is the SMAJ5.0CA-13 discontinued? A: The SMAJ5.0CA-13 is discontinued at DiGi Electronics. Active equivalent parts from multiple manufacturers ensure continued availability for new designs and production support.
