SMBJ90-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBJ90-E3/52 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component is classified as obsolete but remains in stock with 1034 units available. The SMBJ90-E3/52 operates with a 90V reverse standoff voltage and provides 160V maximum clamping voltage at peak pulse current, making it suitable for general-purpose transient protection applications in surface-mount configurations.

Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs and long-term supply chain continuity. Substitute parts maintain the same reverse standoff voltage (90V) and package form factor (DO-214AA/SMB) while offering comparable electrical performance and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ90-E3/52 is determined by the following critical parameters:

• Reverse Standoff Voltage (Typ): Must be 90V to maintain circuit protection threshold compatibility
• Package / Case: Must be DO-214AA or SMB to ensure mechanical and thermal compatibility with existing PCB layouts
• Unidirectional Channels: Must be 1 channel to match the original polarity configuration
• Mounting Type: Must be Surface Mount to align with assembly process requirements
• RoHS Status: Must be ROHS3 Compliant to meet regulatory requirements
• Moisture Sensitivity Level: Must be 1 (Unlimited) to match handling and storage specifications

Substitute parts are grouped into two categories based on electrical performance:

Category A - Direct Electrical Match (160V Clamping):

• SMBJ90E3/TR13 (Microchip Technology)

Category B - Comparable Performance (146V Clamping, Higher Peak Pulse Current):

• SMBJ90A-E3/52 (Vishay General Semiconductor - Diodes Division)
• SMBJ90A (MDD)
• SMBJ90A-13-F (Diodes Incorporated)
• TV06B900J-G (Comchip Technology)

All substitute parts maintain the 90V reverse standoff voltage and DO-214AA/SMB package form factor. Category B parts offer slightly lower clamping voltage (146V) but compensate with higher peak pulse current (4.1A or 4.11A versus 3.8A), resulting in equivalent or superior transient suppression capability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

SMBJ90E3/TR13 (Microchip Technology) provides the closest electrical match with 160V clamping voltage and 3.8A peak pulse current identical to the original SMBJ90-E3/52. This part is active and ROHS3 compliant. The extended operating temperature range (-65 to 150°C) offers improved thermal margin compared to the original specification (-55 to 150°C).

For Active Supply Chain Continuity:

SMBJ90A-E3/52 (Vishay General Semiconductor - Diodes Division) maintains the same manufacturer lineage as the original part and is currently active with 12,200 units in stock. This part features 146V clamping voltage and 4.1A peak pulse current, providing enhanced transient suppression capability within the same power budget (600W).

For High-Volume Availability:

SMBJ90A (MDD) offers the largest inventory (300,200 units) with active product status. This part is suitable for applications where supply chain security is prioritized. The 146V clamping voltage and 4.1A peak pulse current maintain equivalent transient protection performance.

For Multi-Source Flexibility:

SMBJ90A-13-F (Diodes Incorporated) and TV06B900J-G (Comchip Technology) provide alternative sourcing options from established TVS diode manufacturers. Both parts meet all substitution criteria with 146V clamping voltage and comparable peak pulse current specifications.

All recommended substitutes maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and DO-214AA/SMB package compatibility.

Frequently Asked Questions (FAQ)

Q: Can SMBJ90A-E3/52 be used as a direct replacement for SMBJ90-E3/52?

A: Yes. Both parts share identical reverse standoff voltage (90V), breakdown voltage (100V minimum), package form factor (DO-214AA/SMB), and operating temperature range (-55 to 150°C). The SMBJ90A-E3/52 features 146V clamping voltage versus 160V on the original, but compensates with higher peak pulse current (4.1A versus 3.8A), maintaining equivalent transient suppression performance within the 600W power budget.

Q: What is the difference between 160V and 146V clamping voltage?

A: Clamping voltage is the maximum voltage across the TVS diode during transient suppression at peak pulse current. The SMBJ90-E3/52 clamps at 160V maximum, while SMBJ90A variants clamp at 146V maximum. Lower clamping voltage provides tighter voltage regulation during transient events. Both values are within acceptable ranges for general-purpose transient protection applications.

Q: Are all substitute parts available in the same packaging options?

A: All substitute parts are available in DO-214AA/SMB surface-mount package form factor, ensuring mechanical compatibility with existing PCB layouts. Packaging options (Cut Tape, Digi-Reel, Tape & Reel) vary by manufacturer and distributor but do not affect electrical performance or board-level compatibility.

Q: Which substitute part has the best long-term availability?

A: SMBJ90A (MDD) has the highest inventory level (300,200 units) and active product status, providing the strongest supply chain continuity. SMBJ90A-E3/52 (Vishay) with 12,200 units and SMBJ90A-13-F (Diodes Incorporated) with 15,400 units also offer robust availability.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original SMBJ90-E3/52.

Q: What is the operating temperature range difference between substitutes?

A: SMBJ90E3/TR13 (Microchip) operates from -65 to 150°C, providing the widest temperature margin. SMBJ90A-E3/52 and SMBJ90A-13-F operate from -55 to 150°C, matching the original specification. SMBJ90A (MDD) operates from -50 to 150°C. All ranges are suitable for standard industrial and consumer applications.

Q: Can I mix different substitute parts in the same design?

A: Yes. All substitute parts maintain the same reverse standoff voltage (90V), breakdown voltage (100V minimum), and package form factor (DO-214AA/SMB). Mixing parts from different manufacturers is acceptable from an electrical and mechanical standpoint, though single-source designs are preferred for manufacturing consistency.
