1SMB10A TR13 PBFREE Equivalent & Substitute Parts

Part Overview

The 1SMB10A TR13 PBFREE is a unidirectional transient voltage suppressor (TVS) diode manufactured by Central Semiconductor Corp, designed for general-purpose overvoltage protection in surface-mount applications. This component operates with a 10V reverse standoff voltage and provides 17V maximum clamping voltage at peak pulse current of 35.3A, delivering 600W peak pulse power dissipation. The part is classified as Active status and is fully RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are necessary when the original manufacturer's stock is unavailable, when alternative sourcing reduces procurement lead times, or when design flexibility permits selection from multiple qualified manufacturers offering identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the 1SMB10A TR13 PBFREE is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 10V
• Voltage - Breakdown (Min): 11.1V (or 11V minimum acceptable)
• Voltage - Clamping (Max) @ Ipp: 17V
• Current - Peak Pulse (10/1000µs): 35.3A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Unidirectional Channels: 1
• RoHS Status: ROHS3 Compliant

All substitute parts listed maintain identical electrical performance specifications and package compatibility. Variations in operating temperature range and packaging format (Tape & Reel vs. Cut Tape) do not affect functional substitution for general-purpose TVS applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are Active status components with full RoHS3 compliance and REACH unaffected designation, meeting the same regulatory and environmental requirements as the original 1SMB10A TR13 PBFREE.

SMBJ10A-TP (Micro Commercial Co) offers the widest operating temperature range (-55 to 175°C), providing additional thermal margin for applications requiring extended high-temperature performance.

SMBJ10A (MDD) provides the highest inventory availability (113,100 pcs) and represents the most readily accessible substitute for immediate procurement needs.

SMBJ10A-E3/52 (Vishay General Semiconductor - Diodes Division) is supplied in Cut Tape & Digi-Reel® format, suitable for applications requiring flexible packaging options beyond standard Tape & Reel delivery.

SMBJ10A-13-F (Diodes Incorporated) maintains the SMBJ series designation with standard Tape & Reel packaging and mid-range inventory availability (7,330 pcs).

Selection among these substitutes should be based on procurement availability, packaging format requirements, and thermal operating range specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can SMBJ10A-TP be used as a direct replacement for 1SMB10A TR13 PBFREE?

A: Yes. Both components share identical electrical specifications (10V standoff, 17V clamping, 35.3A peak pulse current, 600W peak power) and the same DO-214AA SMB package. The SMBJ10A-TP offers an extended operating temperature range (-55 to 175°C vs. -65 to 150°C), which does not prevent substitution but may provide additional thermal capability.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape & Digi-Reel® (as offered with SMBJ10A-E3/52) provides components on cut tape segments, accommodating lower-volume or mixed-component assembly processes. Both formats contain identical components in the same DO-214AA SMB package.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification and REACH unaffected status, matching the regulatory compliance of the original 1SMB10A TR13 PBFREE.

Q: Does the operating temperature range difference affect substitution suitability?

A: Operating temperature range variations do not prevent functional substitution for general-purpose TVS applications. The original part specifies -65 to 150°C; substitute parts range from -50 to 175°C. Selection should be based on the actual thermal requirements of the target circuit. Parts with narrower ranges (such as SMBJ10A at -50 to 150°C) remain suitable for applications operating within those boundaries.

Q: What is the significance of the SMBJ series designation?

A: SMBJ is a standard industry series designation for surface-mount TVS diodes in DO-214AA packages. All substitute parts bearing the SMBJ10A designation conform to this series standard, ensuring mechanical and electrical compatibility across manufacturers.

Q: Can I mix manufacturers in the same circuit board assembly?

A: Yes. All listed parts meet identical electrical and mechanical specifications and carry equivalent compliance certifications. Mixed-manufacturer sourcing is permissible for production flexibility and supply chain resilience.
