Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical specifications of the SMBJ14C-E3/5B. Selection should prioritize active product status and compliance certifications:

SMBJ14CA-E3/5B (Vishay) provides the closest electrical match with identical clamping voltage (25.8V) and maintains the same operating temperature range as the original part. This part is active and ROHS3 compliant.

SMBJ14CE3/TR13 (Microchip Technology) offers identical electrical performance with extended operating temperature range (-65°C minimum) and is active with ROHS3 compliance.

SMBJ14CA-13-F (Diodes Incorporated) and SMBJ14CAE3/TR13 (Microchip Technology) provide functionally equivalent performance with minor clamping voltage variation (23.2V) and are both active with ROHS3 compliance.

SMBJ14CA (MDD) is available in high inventory volume (30,100 pcs) with active status and ROHS3 compliance, though operating temperature minimum is -50°C.

TV06B140JB-G (Comchip Technology) is functionally equivalent with active status and ROHS3 compliance, though operating temperature range is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can SMBJ14CA-E3/5B directly replace SMBJ14C-E3/5B?

A: Yes. Both parts share identical reverse standoff voltage (14V), breakdown voltage (15.6V), package (DO-214AA, SMB), and operating temperature range (-55°C ~ 150°C). The clamping voltage variation (23.2V vs 25.8V) and peak pulse current variation (25.9A vs 23.3A) fall within acceptable substitution parameters for general-purpose transient suppression applications.

Q: What is the difference between SMBJ14CA and SMBJ14CA-E3/5B?

A: Both parts are electrically equivalent with 14V reverse standoff and 15.6V breakdown voltage. SMBJ14CA-E3/5B specifies -55°C ~ 150°C operating temperature, while SMBJ14CA (MDD) specifies -50°C ~ 150°C. The E3/5B designation indicates specific packaging and tape configuration. Selection depends on temperature requirements and packaging preferences.

Q: Are Microchip Technology SMBJ14CE3/TR13 and SMBJ14CAE3/TR13 interchangeable?

A: Both Microchip parts are functionally equivalent with 14V reverse standoff and 15.6V breakdown voltage in DO-214AA package. SMBJ14CE3/TR13 has 25.8V clamping voltage and 23.3A peak pulse current, while SMBJ14CAE3/TR13 has 23.2V clamping voltage and 25.8A peak pulse current. Both support extended operating temperature range (-65°C ~ 150°C). Selection depends on specific clamping voltage requirements.

Q: Does package type affect substitution compatibility?

A: All listed substitutes use DO-214AA (SMB) surface mount package, ensuring mechanical and footprint compatibility. Tape & Reel (TR) and Cut Tape (CT) packaging variations are handling and delivery formats that do not affect electrical performance or PCB assembly compatibility.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts listed are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080. All parts have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions.
