SMBJ5.0A-HRA Equivalent & Substitute Parts

Part Overview

The SMBJ5.0A-HRA is a unidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 5V reverse standoff voltage with a 9.2V maximum clamping voltage and 65.3A peak pulse current capability in a DO-214AA (SMB) package. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when electrical characteristics and mechanical compatibility remain within specified tolerances for the intended application.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ5.0A-HRA are qualified based on electrical parameter equivalence and mechanical compatibility. The critical parameters determining substitution eligibility are:

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Breakdown (Min): 6.4V
• Voltage - Clamping (Max) @ Ipp: 9.2V
• Current - Peak Pulse (10/1000µs): 65.3A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB (surface mount)
• Operating Temperature Range: -65°C to 150°C (TJ)

Parts meeting these specifications across all parameters are classified as direct electrical and mechanical equivalents. Packaging format variations (Tape & Reel versus Cut Tape) do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The SMBJ5.0A manufactured by EVVO Semi qualifies as a direct substitute for the SMBJ5.0A-HRA. Both components are active products with identical electrical specifications across all critical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and power dissipation. Both meet ROHS3 compliance requirements and operate across the same temperature range. Surface-mount package compatibility (DO-214AA, SMB) is maintained, ensuring mechanical interchangeability in PCB layouts. Packaging format differences (Tape & Reel versus Cut Tape) represent logistics variations only and do not affect component performance or installation.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for a part to be considered a substitute for the SMBJ5.0A-HRA?

A: The reverse standoff voltage (5V), breakdown voltage (6.4V minimum), clamping voltage (9.2V maximum), peak pulse current (65.3A), and peak pulse power (600W) must all match exactly. Operating temperature range (-65°C to 150°C) and package type (DO-214AA, SMB) must also be identical.

Q: Are Tape & Reel and Cut Tape packaging formats interchangeable?

A: Yes. Both packaging formats contain the same component with identical electrical and mechanical specifications. The packaging format affects only the delivery and handling method, not the component's functional performance or PCB installation.

Q: Can the SMBJ5.0A from EVVO Semi be used in place of the Littelfuse SMBJ5.0A-HRA without circuit redesign?

A: Yes. The EVVO Semi SMBJ5.0A meets all electrical and mechanical requirements of the SMBJ5.0A-HRA. No circuit modifications are required for direct substitution.

Q: What compliance certifications apply to both the main part and substitute?

A: Both components are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are classified under ECCN EAR99 with HTSUS code 8541.10.0080.

Q: Are there any temperature or environmental limitations that differ between these parts?

A: No. Both components operate across the identical temperature range of -65°C to 150°C (junction temperature) and share the same moisture sensitivity classification.
