SMBJ64AE3/TR13 Transient Voltage Suppressor

Part Overview

The SMBJ64AE3/TR13 is an active Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose voltage transient protection in surface-mount applications. This unidirectional Zener-type device operates across a temperature range of -65°C to 150°C and is available in tape and reel packaging with 889 pieces in current stock. Identifying compatible substitute parts becomes necessary when managing supply chain constraints, evaluating alternative manufacturer options, or addressing specific packaging or inventory requirements while maintaining equivalent electrical and mechanical functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ64AE3/TR13 are qualified based on electrical equivalence and mechanical compatibility. The critical parameters determining substitutability are:

• Voltage - Reverse Standoff (Typ): 64V nominal operating point
• Voltage - Breakdown (Min): 71.1V minimum breakdown threshold
• Voltage - Clamping (Max) @ Ipp: 103V maximum clamping voltage at peak pulse current
• Current - Peak Pulse (10/1000µs): 5.8A nominal peak pulse current rating
• Power - Peak Pulse: 600W maximum power dissipation
• Package / Case: DO-214AA (SMB) surface-mount package
• Operating Temperature Range: Specified by each manufacturer
• Compliance: ROHS3 compliant, MSL 1, REACH Unaffected, ECCN EAR99

All identified substitute parts maintain identical or equivalent voltage and current ratings within the specified tolerances, support the same DO-214AA/SMB package form factor, and are rated for surface-mount assembly with the same regulatory compliance framework.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status with equivalent electrical specifications and identical package form factors. The SMBJ64A-E3/52 (Vishay) offers the highest inventory availability at 45,400 pieces and is manufactured by Vishay General Semiconductor, a tier-1 supplier in the diode industry. The SMBJ64A (Meritek) provides substantial inventory (23,100 pieces) with marginally higher peak pulse current (5.83A versus 5.8A), both within specification tolerance. The SMBJ64A-13-F (Diodes Incorporated) maintains full electrical and regulatory compliance with 3,657 pieces available.

A critical consideration is operating temperature range: the Microchip SMBJ64AE3/TR13 operates to -65°C, while all substitute parts from Meritek, Vishay, and Diodes are rated to -55°C minimum. For applications requiring operation below -55°C, the original Microchip device is required. For standard industrial temperature ranges (-55°C to 150°C), all substitutes are electrically and mechanically equivalent. All parts carry ROHS3 compliance, MSL 1 (unlimited moisture sensitivity), REACH unaffected status, and ECCN EAR99 classification.

Frequently Asked Questions (FAQ)

Q: Can SMBJ64A (Meritek) directly replace SMBJ64AE3/TR13 (Microchip)?

A: Electrical substitution is valid within standard industrial temperature ranges. The Meritek device maintains identical voltage ratings (64V standoff, 71.1V breakdown minimum, 103V clamp maximum) and 5.83A peak pulse current, which is within tolerance of the 5.8A specification. Both devices share the DO-214AA/SMB package and equivalent power handling (600W). However, the Meritek part is rated only to -55°C minimum operating temperature, compared to -65°C for the Microchip device. Applications requiring sub-55°C operation must use the original Microchip SMBJ64AE3/TR13.

Q: What is the difference between SMBJ64A-E3/52 and SMBJ64AE3/TR13?

A: These parts are manufactured by different suppliers (Vishay versus Microchip) with equivalent electrical specifications. The SMBJ64A-E3/52 is Vishay's TransZorb® series variant packaged in tape and reel format. Both devices maintain 64V reverse standoff, 71.1V breakdown minimum, and 103V clamping voltage. Operating temperature ratings differ: Microchip extends to -65°C while Vishay is rated -55°C to 150°C. The Vishay device offers significantly higher inventory availability (45,400 pieces).

Q: Are all substitute parts suitable for tape and reel automation?

A: The SMBJ64AE3/TR13 and SMBJ64A-E3/52 are specified in tape and reel (TR) packaging for automated placement. The SMBJ64A (Meritek) and SMBJ64A-13-F (Diodes) are also available in tape and reel format, making them compatible with standard surface-mount assembly processes. All four devices use the DO-214AA/SMB footprint.

Q: Which substitute offers the best supply continuity?

A: The SMBJ64A-E3/52 (Vishay) maintains the largest active inventory at 45,400 pieces. The SMBJ64A (Meritek) provides 23,100 pieces. Both represent substantially higher availability than the original Microchip part (889 pieces), offering improved supply chain resilience.

Q: Are all substitute parts RoHS3 compliant?

A: All identified substitute parts carry ROHS3 compliance, MSL 1 (unlimited moisture sensitivity), REACH unaffected status, and ECCN EAR99 classification. They meet the same regulatory and environmental compliance standards as the SMBJ64AE3/TR13.
