SMBJ10C-E3/5B Equivalent & Substitute Parts

Part Overview

The SMBJ10C-E3/5B is a transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division, designed for general-purpose overvoltage protection in surface-mount applications. This part operates with a 10V reverse standoff voltage and provides 18.8V clamping at peak pulse current. The product is currently obsolete, necessitating identification of active equivalent parts that maintain electrical and mechanical compatibility for new designs and production continuity.

Substitute Part Grouping Explanation

Substitution of the SMBJ10C-E3/5B is determined by strict electrical and mechanical parameter matching:

Critical Matching Parameters:

Reverse Standoff Voltage: 10V (Typ)
Breakdown Voltage: 11.1V (Min)
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Bidirectional Channels: 1
Type: Zener
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

Clamping Voltage (Max) @ Ipp: 17V to 18.8V
Peak Pulse Current (10/1000µs): 31.9A to 37A
Operating Temperature Range: -50°C to -65°C minimum; 150°C to 175°C maximum
Packaging Format: Tape & Reel (TR), Cut Tape (CT), or bulk

Substitute parts must maintain the same voltage protection class (10V standoff) and physical package to ensure PCB compatibility and circuit protection equivalence. Variations in peak pulse current and clamping voltage within the specified ranges do not affect functional substitution for general-purpose applications.

Engineering Selection Recommendations

Primary Recommendation: SMBJ10CE3/TR13 (Microchip Technology)

This part provides electrical equivalence to the original SMBJ10C-E3/5B with identical clamping voltage (18.8V) and peak pulse current (31.9A). It is currently active in production with ROHS3 compliance and extended operating temperature range (-65°C to 150°C). Tape & Reel packaging ensures compatibility with automated assembly processes.

Secondary Recommendations: SMBJ10CA-E3/5B, SMBJ10CA-13-F, SMBJ10CA-TP, SMBJ10CA-TR, SMBJ10CAE3/TR13

These parts maintain the critical 10V standoff voltage and DO-214AA package specification. Clamping voltage ranges from 17V to 18.8V and peak pulse current from 35.3A to 37A, all within acceptable substitution parameters. All are active products with ROHS3 compliance. Selection among these options depends on packaging availability (Tape & Reel vs. bulk), temperature range requirements, and supply chain considerations.

Alternative: SMBJ10CA (MDD)

This part is suitable for applications where operating temperature does not exceed -50°C minimum. It offers the highest inventory availability (443,100 pcs) and represents a cost-effective option for high-volume production.

Frequently Asked Questions (FAQ)

Q: Can SMBJ10CA-E3/5B replace SMBJ10C-E3/5B directly on the PCB?

A: Yes. Both parts share identical reverse standoff voltage (10V), breakdown voltage (11.1V), and DO-214AA package specification. The clamping voltage difference (17V vs. 18.8V) falls within acceptable substitution parameters for general-purpose transient suppression. Electrical performance remains equivalent for circuit protection.

Q: What is the difference between SMBJ10CE3/TR13 and SMBJ10CAE3/TR13?

A: Both are Microchip Technology products in Tape & Reel packaging with identical electrical specifications (10V standoff, 11.1V breakdown, -65°C to 150°C operating range). SMBJ10CE3/TR13 provides 18.8V clamping at 31.9A peak pulse current, matching the original part exactly. SMBJ10CAE3/TR13 provides 17V clamping at 35.3A peak pulse current. Selection depends on whether exact clamping voltage matching is required for the application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and reliability standards.

Q: Does packaging format (Tape & Reel vs. bulk) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly process compatibility. Electrical specifications remain identical regardless of packaging configuration. Selection should be based on manufacturing process requirements and supply chain logistics.

Q: Which substitute part has the widest operating temperature range?

A: SMBJ10CA-TP (Micro Commercial Co) operates from -55°C to 175°C, providing the widest temperature margin. This part is suitable for applications requiring extended high-temperature performance.

Q: Can I use SMBJ10CA (MDD) in applications requiring -55°C minimum temperature operation?

A: No. SMBJ10CA operates from -50°C minimum, which does not meet the original part's -55°C specification. For applications requiring -55°C minimum temperature, select SMBJ10CA-E3/5B, SMBJ10CE3/TR13, SMBJ10CA-13-F, SMBJ10CA-TP, SMBJ10CA-TR, or SMBJ10CAE3/TR13.
