Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ5.0A-M3/5B is determined by the following criteria:

Electrical Parameters (Critical):

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Breakdown (Min): 6.4V
• Voltage - Clamping (Max) @ Ipp: 9.2V
• Current - Peak Pulse (10/1000µs): 65.2A (±0.1A tolerance acceptable)
• Power - Peak Pulse: 600W
• Type: Zener, Unidirectional (1 channel)

Mechanical Parameters (Critical):

• Package / Case: DO-214AA or SMB equivalent
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Packaging Format (Interchangeable):

• Tape & Reel (TR), Cut Tape (CT), or Digi-Reel® formats are functionally equivalent for component selection

Substitute parts must match all electrical and mechanical parameters. Packaging format differences do not affect electrical compatibility. Operating temperature range variations are noted but do not disqualify substitution when the specified operating range is within the substitute part's capability.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Electrical and Mechanical Parameters):

SMBJ5.0A-E3/52, SMBJ5.0A-E3/5B, 1SMB5.0A TR13 PBFREE, SMBJ5.0A-13-F, SMBJ5.0A-TP, and SMBJ5.0AE3/TR13 are direct functional equivalents to the SMBJ5.0A-M3/5B. All parts maintain identical voltage ratings (5V standoff, 6.4V breakdown, 9.2V clamping), peak pulse current (65.2A), and power dissipation (600W). All substitute parts are ROHS3 compliant and carry MSL 1 rating. Packaging format differences (Tape & Reel, Cut Tape, Digi-Reel®) do not affect electrical performance or PCB assembly compatibility.

Extended Temperature Range Options:

1SMB5.0A TR13 PBFREE, SMBJ5.0AE3/TR13, and SMBJ5.0A (EVVO Semi) offer extended lower operating temperature limits (-65°C minimum) compared to the original part (-55°C minimum). These parts are suitable for applications requiring enhanced cold-temperature performance while maintaining all other electrical specifications.

Higher Temperature Capability:

SMBJ5.0A-TP (Micro Commercial Co) extends the upper operating temperature to 175°C, compared to 150°C for the original part. This option is applicable for high-temperature environment applications.

Compliance Verification:

SMBJ5V0A (Fairchild Semiconductor) matches all electrical and mechanical parameters but does not specify RoHS or MSL compliance in the provided data. Compliance verification with the component supplier is required before selection for regulated applications.

Peak Pulse Current Tolerance:

SMBJ5.0A (EVVO Semi) specifies 65.3A peak pulse current, representing a 0.1A variance from the 65.2A specification. This minor tolerance variation remains within acceptable engineering margins for TVS diode applications and does not disqualify the part as a functional equivalent.

Frequently Asked Questions (FAQ)

Q: Can I substitute SMBJ5.0A-E3/52 for SMBJ5.0A-M3/5B?

A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications (5V standoff, 6.4V breakdown, 9.2V clamping, 65.2A peak pulse, 600W power). The difference is packaging format: SMBJ5.0A-E3/52 is supplied in Cut Tape (CT) format while SMBJ5.0A-M3/5B is Tape & Reel (TR). Electrical performance and PCB assembly compatibility are identical.

Q: What is the difference between the various Vishay part numbers (SMBJ5.0A-M3/5B, SMBJ5.0A-E3/52, SMBJ5.0A-E3/5B)?

A: These are all Vishay SMBJ5.0A variants with identical electrical characteristics. The suffix designations indicate packaging and reel configuration differences. The "-M3/5B" denotes one reel configuration, "-E3/52" denotes another, and "-E3/5B" denotes a third. All are functionally equivalent for circuit design purposes.

Q: Can I use 1SMB5.0A TR13 PBFREE as a substitute?

A: Yes. The 1SMB5.0A TR13 PBFREE (Central Semiconductor Corp) is electrically identical to the SMBJ5.0A-M3/5B with matching voltage ratings and peak pulse current. The part is ROHS3 compliant and lead-free. The extended operating temperature range (-65°C to 150°C) provides additional capability for cold-temperature applications.

Q: Are there any compatibility issues with different manufacturers?

A: No. All listed substitute parts maintain identical electrical specifications and DO-214AA (SMB) package compatibility. Cross-manufacturer substitution is valid when electrical parameters and package specifications match. Verify compliance certifications (RoHS, MSL) with your application requirements.

Q: What does the 65.2A peak pulse current specification mean?

A: Peak pulse current (Ipp) is the maximum instantaneous current the TVS diode can conduct during a transient event under specified pulse conditions (10/1000µs waveform). All listed equivalents maintain this 65.2A specification, ensuring identical transient suppression performance.

Q: Can I use SMBJ5.0A-TP for applications requiring higher temperature operation?

A: Yes. SMBJ5.0A-TP (Micro Commercial Co) extends the maximum operating temperature to 175°C compared to 150°C for most other variants. All other electrical specifications remain identical. This part is suitable for high-temperature environment applications.

Q: Is SMBJ5V0A (Fairchild) a valid substitute?

A: SMBJ5V0A matches all electrical and mechanical specifications but does not specify RoHS or MSL compliance in available documentation. Confirm compliance status with the supplier before selection for regulated or high-reliability applications.

Q: What is the significance of the 0.1A difference in peak pulse current for EVVO Semi's SMBJ5.0A?

A: EVVO Semi's SMBJ5.0A specifies 65.3A peak pulse current versus 65.2A for the original part. This 0.1A variance is within normal manufacturing tolerance for TVS diodes and does not affect functional equivalence or circuit performance.

Q: Can packaging format affect my PCB assembly process?

A: Packaging format (Tape & Reel, Cut Tape, Digi-Reel®) affects supply and handling but not electrical performance or PCB compatibility. All formats use the same DO-214AA (SMB) component body. Select based on your assembly equipment and supply chain requirements.
