SMBJ100D-M3/H Equivalent & Substitute Parts

Part Overview

The SMBJ100D-M3/H is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay's TransZorb® series, designed for general-purpose transient protection applications. This surface-mount component operates across a junction temperature range of -55°C to 150°C and is RoHS3 compliant. The part is currently active in production with 850 units in stock, making it readily available for new designs and production requirements. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and access to alternative packaging or inventory options when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ100D-M3/H is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Reverse Standoff Voltage: 100V (Typ)
• Unidirectional channel configuration: 1 channel
• Package type: DO-214AA (SMB)
• Mounting type: Surface Mount
• Series classification: TransZorb® Zener diode
• Operating temperature range: -55°C to 150°C
• RoHS3 compliance and MSL rating

Allowable Variation Range:

• Voltage - Breakdown (Min): 111V to 113V
• Voltage - Clamping (Max) @ Ipp: 159V to 162V
• Current - Peak Pulse (10/1000µs): 3.7A to 3.77A
• Power - Peak Pulse: 600W (fixed)

The SMBJ100A-E3/52 meets all critical matching parameters and falls within the allowable variation ranges for electrical performance specifications. Both parts share identical base product classification (SMBJ100), manufacturer origin, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ100D-M3/H and SMBJ100A-E3/52 are active production parts from Vishay with full RoHS3 compliance and identical MSL ratings. Selection between these parts should be based on the following factors:

Packaging Format Consideration: The primary difference between these parts is the packaging format. The SMBJ100D-M3/H is supplied in Cut Tape (CT) and Digi-Reel® format, while the SMBJ100A-E3/52 is supplied in standard Tape & Reel (TR) format. Choose based on your assembly process requirements and tape specifications.

Electrical Performance: The SMBJ100A-E3/52 exhibits marginally lower breakdown voltage (111V minimum versus 113V) and slightly higher clamping voltage (162V maximum versus 159V), with fractionally lower peak pulse current (3.7A versus 3.77A). These variations remain within the functional tolerance band for general-purpose transient protection applications and do not compromise circuit protection performance.

Inventory and Availability: The SMBJ100A-E3/52 currently has higher inventory availability (1650 units) compared to the SMBJ100D-M3/H (850 units), which may influence procurement decisions for high-volume production runs.

Frequently Asked Questions (FAQ)

Q: Can SMBJ100A-E3/52 be used as a direct replacement for SMBJ100D-M3/H in existing designs?

A: Yes. Both parts share identical electrical specifications within functional tolerance, the same DO-214AA package footprint, and equivalent thermal performance. The only difference is the packaging format (Cut Tape versus standard Tape & Reel). PCB assembly compatibility is maintained.

Q: What is the significance of the different clamping voltages (159V vs 162V)?

A: Both values fall within the acceptable clamping range for 100V standoff TVS diodes. The 3V difference represents normal manufacturing tolerance and does not affect circuit protection effectiveness in general-purpose applications.

Q: Does the packaging format difference affect component performance?

A: No. The packaging format (Cut Tape versus Tape & Reel) affects only the delivery and handling method, not electrical or thermal performance. Selection should be based on your assembly equipment compatibility and tape specifications.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both SMBJ100D-M3/H and SMBJ100A-E3/52 operate across -55°C to 150°C junction temperature, making them functionally equivalent for thermal performance requirements.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited). They meet identical regulatory and environmental standards.
