Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ90D-M3/H is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 90V
• Voltage - Breakdown (Min): 100V minimum
• Voltage - Clamping (Max) @ Ipp: within acceptable operating range
• Current - Peak Pulse (10/1000µs): 4.1A minimum
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature: -55°C ~ 150°C (TJ)
• RoHS Status: ROHS3 Compliant

The substitute part SMBJ90A-E3/52 meets all critical electrical and mechanical parameters within the specified tolerances, maintaining functional equivalence for general-purpose TVS diode applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ90D-M3/H and SMBJ90A-E3/52 are active production parts manufactured by Vishay General Semiconductor - Diodes Division within the TransZorb® series. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings. The electrical parameters remain within acceptable operating margins for general-purpose TVS diode applications. Selection between these parts may be based on packaging format availability (Tape & Reel versus Cut Tape & Digi-Reel®) and inventory lead times.

Frequently Asked Questions (FAQ)

Q: Can SMBJ90A-E3/52 be used as a direct replacement for SMBJ90D-M3/H?

A: Yes. Both parts share identical reverse standoff voltage (90V), equivalent breakdown voltage specifications (102V vs. 100V minimum), and matching power dissipation ratings (600W). The clamping voltage differential (144V vs. 146V) and peak pulse current variation (4.17A vs. 4.1A) remain within acceptable operating tolerances for general-purpose transient suppression circuits.

Q: Are there packaging differences between these parts?

A: Both parts use the DO-214AA (SMB) surface mount package. The primary difference is packaging format: SMBJ90D-M3/H is supplied in Tape & Reel (TR) format, while SMBJ90A-E3/52 is available in Cut Tape (CT) & Digi-Reel® format. Both are suitable for automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SMBJ90D-M3/H and SMBJ90A-E3/52 are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). Both operate across the same temperature range (-55°C to 150°C junction temperature).

Q: What determines substitution eligibility for SMBJ90 series TVS diodes?

A: Substitution is based on matching reverse standoff voltage (90V), minimum breakdown voltage specification (100V or higher), equivalent power dissipation capability (600W), identical package format (DO-214AA, SMB), and compatible operating temperature range. Peak pulse current and clamping voltage must remain within acceptable circuit design margins.
