SMBJ6.5D-M3/H Equivalent & Substitute Parts

Part Overview

The SMBJ6.5D-M3/H is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, part of the TransZorb® series. This surface mount component operates in the DO-214AA (SMB) package and is designed for general-purpose transient voltage suppression applications. The part is currently Active in product status and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ6.5D-M3/H is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Clamping (Max) @ Ipp: within acceptable tolerance range
• Current - Peak Pulse (10/1000µs): within acceptable tolerance range
• Power - Peak Pulse: 600W minimum
• Package / Case: DO-214AA, SMB (surface mount)
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional (1 channel)
• Operating Temperature Range: -55°C to 150°C (TJ)
• RoHS3 Compliance: Required
• Product Status: Active

The substitute part SMBJ6.5A-E3/52 maintains identical reverse standoff voltage, equivalent clamping voltage performance, comparable peak pulse current capability, and identical package specifications. Both parts are manufactured by the same supplier, share the same base product number (SMBJ6.5), and maintain full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ6.5D-M3/H and SMBJ6.5A-E3/52 are Active products manufactured by Vishay General Semiconductor - Diodes Division and maintain full ROHS3 compliance. The substitute part meets all electrical parameter requirements within acceptable engineering tolerances. Selection between these parts may be based on packaging format availability: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) & Digi-Reel® format. Both parts share identical regulatory certifications (REACH Unaffected, EAR99 ECCN classification, and HTSUS code 8541.10.0080).

Frequently Asked Questions (FAQ)

Q: Can SMBJ6.5A-E3/52 be used as a direct replacement for SMBJ6.5D-M3/H?

A: Yes. Both parts maintain identical reverse standoff voltage (6.5V), equivalent clamping voltage performance (11V vs. 11.2V), comparable peak pulse current (54.5A vs. 53.6A), and identical power dissipation (600W). Package specifications and mounting type are identical.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel is a continuous reel format suitable for high-volume automated assembly. Cut Tape & Digi-Reel® provides flexibility for lower-volume or mixed-component orders. The electrical and mechanical specifications of the component remain unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both SMBJ6.5D-M3/H and SMBJ6.5A-E3/52 are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Do these parts have identical operating temperature ranges?

A: Yes. Both parts operate across -55°C to 150°C (TJ) junction temperature range.

Q: What is the base product number for these parts?

A: Both parts share the base product number SMBJ6.5, indicating they are variants within the same product family with identical voltage rating specifications.
