SMBJ13CA-TP Equivalent & Substitute Parts

Part Overview

The SMBJ13CA-TP is a transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection in surface-mount applications. This zener-type TVS diode operates with a 13V reverse standoff voltage and provides 21.5V clamping at peak pulse current, delivering 600W peak pulse power dissipation in a compact DO-214AA (SMB) package. The part is active in production status and ROHS3 compliant. Equivalent and substitute parts are identified based on matching electrical performance parameters and package compatibility to support design flexibility, supply chain alternatives, and procurement optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ13CA-TP are qualified based on the following critical parameters:

• Voltage - Reverse Standoff (Typ): 13V
• Voltage - Clamping (Max) @ Ipp: 21.5V
• Current - Peak Pulse (10/1000µs): 27.9A to 28A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Type: Zener
• Bidirectional Channels: 1
• RoHS Status: ROHS3 Compliant

All identified substitutes maintain these core electrical and mechanical specifications, ensuring functional equivalence in circuit protection applications. Variations in operating temperature range and packaging format (Tape & Reel vs. Cut Tape) do not affect electrical performance and represent alternative sourcing options.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance, meeting regulatory requirements for commercial and industrial applications. Selection among equivalents should be based on:

Availability and lead time from authorized distributors. The MDD SMBJ13CA variant offers the highest inventory (20,461 pcs), providing supply chain stability. The Vishay TransZorb® series (SMBJ13CA-E3/52 and SMBJ13CA-E3/5B) provides established automotive-grade reliability through the TransZorb® product line. The Littelfuse SZ1SMB13CAT3G includes AEC-Q101 automotive qualification and extended low-temperature operation (-65°C), suitable for automotive and harsh-environment applications. The Central Semiconductor 1SMB13CA TR13 PBFREE offers extended low-temperature capability (-65°C) with lead-free construction. Operating temperature range compatibility with the application environment. The SMBJ13CA-TP supports the widest operating range (-55°C to 175°C), making it suitable for high-temperature applications. For standard commercial temperature ranges (-50°C to 150°C), all other substitutes are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can SMBJ13CA-TP be directly replaced with SMBJ13CA from MDD?

A: Yes. Both parts share identical electrical specifications (13V standoff, 21.5V clamping, 27.9A peak pulse, 600W power dissipation) and the same DO-214AA SMB package. The primary difference is operating temperature range (-55°C to 175°C for SMBJ13CA-TP vs. -50°C to 150°C for MDD SMBJ13CA). Direct substitution is valid for applications operating within -50°C to 150°C.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel and Cut Tape are packaging formats for automated assembly. Tape & Reel is supplied on continuous carrier tape for high-volume pick-and-place equipment. Cut Tape is supplied in shorter tape segments for lower-volume or manual assembly. Both formats contain identical components; the choice depends on assembly equipment and order volume requirements.

Q: Are Vishay TransZorb® parts (SMBJ13CA-E3/52, SMBJ13CA-E3/5B) interchangeable with the main part?

A: Yes. Both Vishay variants meet all electrical specifications and package requirements. The TransZorb® designation indicates Vishay's product line branding. The suffix differences (-E3/52 vs. -E3/5B) represent packaging or tape configuration variants but do not affect electrical performance.

Q: Is the Littelfuse SZ1SMB13CAT3G suitable for automotive applications?

A: Yes. The SZ1SMB13CAT3G carries AEC-Q101 automotive qualification and operates across -65°C to 150°C, meeting automotive-grade reliability standards. It is a direct electrical equivalent to SMBJ13CA-TP and suitable for automotive overvoltage protection circuits.

Q: What does ROHS3 compliance mean for this part?

A: ROHS3 compliance indicates the part meets the Restriction of Hazardous Substances Directive 3, restricting lead, cadmium, mercury, and other hazardous materials. All listed substitutes are ROHS3 compliant, ensuring regulatory compliance for commercial, industrial, and consumer applications.

Q: Can I use a substitute part with a lower peak pulse current rating?

A: No. The peak pulse current rating (27.9A to 28A) is a critical specification for transient suppression. Using a part with lower current rating may result in inadequate protection and component failure under transient events. All qualified substitutes maintain the specified 27.9A to 28A rating.
