SMBJ6.5A-HRA Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The SMBJ6.5A-HRA is a unidirectional Zener-type transient voltage suppressor manufactured by Littelfuse Inc. in the DO-214AA (SMB) surface mount package. This component is designed for general-purpose transient voltage suppression applications with a 6.5V reverse standoff voltage and 11.2V maximum clamping voltage. The part is active in production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching electrical characteristics and mechanical compatibility within the SMBJ series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ6.5A-HRA is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Clamping (Max) @ Ipp: 11.2V
• Current - Peak Pulse (10/1000µs): 53.6A nominal tolerance
• Package / Case: DO-214AA or SMB equivalent
• Mounting Type: Surface Mount
• Type: Zener unidirectional
• RoHS3 Compliance: Required

All identified substitute parts maintain these core electrical specifications and package compatibility. Variations in peak pulse current within the 53.6A to 56A range and operating temperature ranges (-55°C to -65°C minimum) are within acceptable substitution parameters for this component category.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts meet the electrical and mechanical requirements for direct replacement of the SMBJ6.5A-HRA. Selection among these alternatives should be based on:

Inventory and Lead Time: SMBJ6.5A (Taiwan Semiconductor Corporation) offers the highest stock availability at 17,957 pieces, followed by SMBJ6V5A at 6,100 pieces. SMBJ6.5A-HRA maintains 649 pieces in stock.

Packaging Format: SMBJ6.5A-HRA and SMBJ6.5A-E3/52 are supplied in Tape & Reel (TR) format. SMBJ6.5A is supplied without specified packaging. SMBJ6.5A-13-F is supplied in Tape & Reel (TR). SMBJ6V5A is supplied in Cut Tape (CT) & Digi-Reel® format.

Temperature Range: SMBJ6.5A-HRA supports the extended lower temperature limit of -65°C, while all substitute parts operate from -55°C minimum. Applications requiring operation below -55°C require the original SMBJ6.5A-HRA.

Compliance and Certifications: All parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring compatibility with standard manufacturing and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can SMBJ6.5A (Taiwan Semiconductor Corporation) directly replace SMBJ6.5A-HRA?

A: Yes. Both parts share identical voltage specifications (6.5V standoff, 11.2V clamping), peak pulse current (56A vs. 53.6A is within acceptable tolerance), power rating (600W), and package format (DO-214AA, SMB). The primary difference is the operating temperature minimum (-55°C vs. -65°C). For applications operating above -55°C, this substitute is fully compatible.

Q: What is the difference between SMBJ6.5A-E3/52 and SMBJ6.5A-HRA?

A: Both parts are electrically identical with 6.5V standoff voltage, 11.2V clamping voltage, and 53.6A peak pulse current. SMBJ6.5A-E3/52 is manufactured by Vishay (TransZorb® series) and supplied in Cut Tape (CT) & Digi-Reel® format, while SMBJ6.5A-HRA is manufactured by Littelfuse and supplied in Tape & Reel (TR) format. The operating temperature minimum is -55°C for the Vishay part versus -65°C for Littelfuse.

Q: Is SMBJ6V5A compatible with SMBJ6.5A-HRA?

A: Yes. SMBJ6V5A (Taiwan Semiconductor Corporation) maintains all critical electrical parameters: 6.5V reverse standoff voltage, 11.2V clamping voltage, and 53.6A peak pulse current. Both use the DO-214AA (SMB) package. The operating temperature range is -55°C to 150°C for SMBJ6V5A compared to -65°C to 150°C for SMBJ6.5A-HRA.

Q: Why does SMBJ6.5A show 56A peak pulse current instead of 53.6A?

A: The 56A specification for SMBJ6.5A (Taiwan Semiconductor Corporation) represents a higher current rating within the same voltage class. This variation is within acceptable tolerance for the SMBJ6.5V series and does not affect substitution compatibility. The component still maintains the 11.2V clamping voltage and 600W power rating.

Q: What packaging options are available for these substitute parts?

A: SMBJ6.5A-HRA and SMBJ6.5A-E3/52 are supplied in Tape & Reel (TR) format. SMBJ6.5A-13-F is supplied in Tape & Reel (TR). SMBJ6V5A is supplied in Cut Tape (CT) & Digi-Reel® format. SMBJ6.5A packaging is not specified in available data. Verify packaging requirements with your procurement process before final selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts—SMBJ6.5A, SMBJ6.5A-13-F, SMBJ6.5A-E3/52, and SMBJ6V5A—maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, matching the compliance profile of SMBJ6.5A-HRA.
