SMBJ54CD-M3/H Equivalent & Substitute Parts

Part Overview

The SMBJ54CD-M3/H is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 54V reverse standoff voltage class and is designed for general-purpose transient protection applications. The device is classified as Active product status and is RoHS3 compliant. Equivalent and substitute parts are identified when component availability is limited or when procurement requirements necessitate alternative sourcing from the same manufacturer's product line while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ54CD-M3/H are identified based on the following critical parameters that determine functional interchangeability:

Mandatory Matching Parameters:

• Reverse Standoff Voltage: 54V (Typ)
• Package / Case: DO-214AA, SMB (surface mount)
• Mounting Type: Surface Mount
• Series: TransZorb®
• Type: Zener
• Bidirectional Channels: 1
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: ±2.5V tolerance
• Current - Peak Pulse (10/1000µs): ±0.2A tolerance
• Power - Peak Pulse: Equal or greater capacity

The substitute part SMBJ54CA-E3/52 meets all mandatory matching criteria and falls within allowable variation ranges for clamping voltage and peak pulse current, confirming functional equivalence within the SMBJ54 base product family.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ54CD-M3/H and SMBJ54CA-E3/52 are Active product status components manufactured by Vishay General Semiconductor - Diodes Division within the TransZorb® series. Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, confirming equivalent environmental and regulatory compliance.

The SMBJ54CA-E3/52 is the manufacturer-recommended substitute for the SMBJ54CD-M3/H. Selection between these parts is determined by availability and procurement requirements, as both devices satisfy the same functional specifications for 54V class TVS diode applications in surface mount DO-214AA packaging.

Frequently Asked Questions (FAQ)

Q: Can SMBJ54CA-E3/52 be used as a direct replacement for SMBJ54CD-M3/H?

A: Yes. Both parts share identical reverse standoff voltage (54V), package type (DO-214AA, SMB), mounting configuration (surface mount), and operating temperature range (-55°C ~ 150°C). The clamping voltage difference (85.9V vs. 87.1V) and peak pulse current difference (7A vs. 6.9A) fall within acceptable engineering tolerances for the SMBJ54 base product family.

Q: Are there any package or footprint differences between these parts?

A: No. Both SMBJ54CD-M3/H and SMBJ54CA-E3/52 use identical DO-214AA (SMB) surface mount packaging. PCB footprints and assembly processes are interchangeable.

Q: What is the significance of the part number suffix differences (CD-M3/H vs. CA-E3/52)?

A: The suffixes indicate different manufacturing date codes and tape reel configurations from Vishay. These designations do not affect electrical performance or functional compatibility. Both parts belong to the SMBJ54 base product family and meet identical electrical specifications within defined tolerances.

Q: Are both parts RoHS compliant?

A: Yes. Both SMBJ54CD-M3/H and SMBJ54CA-E3/52 are ROHS3 compliant and carry identical MSL Level 1 (Unlimited) ratings, confirming equivalent environmental and regulatory compliance for industrial and commercial applications.

Q: Which part should be selected for new designs?

A: Selection is based on current availability and procurement lead times. Both parts are Active status and functionally equivalent. Consult with your component supplier for inventory status and delivery schedules.
