SMBJ64CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ64CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional Zener diode operates with a 64V reverse standoff voltage and provides clamping at 114V maximum, with a peak pulse current rating of 5.3A and 600W peak pulse power dissipation. The component is housed in a DO-214AA (SMB) package and supplied in Tape & Reel (TR) format.

The SMBJ64CE3/TR13 maintains Active product status and is fully RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Substitute parts are identified based on matching electrical parameters within the SMBJ64 base product family, ensuring functional equivalence for circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ64CE3/TR13 are identified within the SMBJ64 base product family. Substitution eligibility is determined by the following critical parameters:

Matching Criteria:

• Voltage - Reverse Standoff (Typ): 64V
• Voltage - Breakdown (Min): 71.1V
• Type: Zener, Bidirectional
• Bidirectional Channels: 1
• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Allowable Variation:

• Voltage - Clamping (Max) @ Ipp: 103V to 114V (within protection circuit tolerance)
• Current - Peak Pulse (10/1000µs): 5.3A to 5.83A (within thermal design margin)
• Operating Temperature: -55°C to -65°C minimum; 150°C maximum

All substitute parts maintain identical reverse standoff and breakdown voltage specifications, ensuring circuit protection thresholds remain unchanged. Clamping voltage and peak pulse current variations fall within acceptable ranges for general-purpose transient suppression applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (SMBJ64CE3/TR13 - Microchip Technology): The original Microchip part is recommended when the extended operating temperature range of -65°C to 150°C is required. This part offers the highest clamping voltage specification (114V maximum), providing additional margin in transient suppression circuits. Active product status and full RoHS3 compliance support long-term supply chain stability.

Alternative Selection (SMBJ64CA-13-F - Diodes Incorporated): The Diodes Incorporated SMBJ64CA-13-F is suitable for applications where the standard operating temperature range of -55°C to 150°C is acceptable. This part maintains identical reverse standoff and breakdown voltage specifications. The lower clamping voltage (103V maximum) and higher peak pulse current (5.8A) are appropriate for circuits designed to these parameters. Cut Tape (CT) and Digi-Reel® packaging options provide flexibility for different procurement workflows. Active product status and full RoHS3 compliance are maintained.

Alternative Selection (SMBJ64CA - Meritek): The Meritek SMBJ64CA is functionally equivalent within the specified parameter ranges, with operating temperature limited to -55°C to 150°C. This part offers the highest peak pulse current rating (5.83A) and lowest clamping voltage (103V), suitable for circuits optimized for these electrical characteristics. Active product status and full RoHS3 compliance are confirmed. Packaging format is not specified in available data.

Compliance Basis: All three parts maintain RoHS3 compliance, REACH Unaffected status, and EAR99 export classification. Selection among these parts is based on specific circuit requirements for operating temperature range, clamping voltage margin, and peak pulse current capacity, with no compliance-based restrictions on substitution.

Frequently Asked Questions (FAQ)

Q: Can SMBJ64CA (Meritek) be used as a direct replacement for SMBJ64CE3/TR13 (Microchip)?

A: Yes, within specified circuit parameters. Both parts share identical reverse standoff voltage (64V) and breakdown voltage (71.1V). The Meritek part has a lower clamping voltage maximum (103V vs. 114V) and higher peak pulse current (5.83A vs. 5.3A). Substitution is valid if the circuit design accommodates these electrical differences. The Meritek part operates at -55°C minimum temperature, compared to -65°C for the Microchip part.

Q: What is the difference between SMBJ64CA and SMBJ64CA-13-F?

A: Both parts are electrically identical with 64V reverse standoff, 71.1V breakdown voltage, 103V clamping voltage, and 5.8A peak pulse current. The primary difference is packaging format: SMBJ64CA-13-F is supplied in Cut Tape (CT) and Digi-Reel® formats by Diodes Incorporated, while SMBJ64CA (Meritek) packaging format is not specified. Both operate across -55°C to 150°C temperature range.

Q: Does the clamping voltage difference (114V vs. 103V) affect circuit compatibility?

A: Clamping voltage determines the maximum voltage applied to protected circuitry during a transient event. The SMBJ64CE3/TR13 clamps at 114V maximum, while substitute parts clamp at 103V maximum. Circuits designed for the 103V clamping specification can use either part. Circuits requiring 114V clamping margin should use the original SMBJ64CE3/TR13. Verify circuit protection requirements before substitution.

Q: Are all three parts suitable for the same PCB assembly process?

A: Yes. All three parts use identical DO-214AA (SMB) surface-mount packages and are compatible with standard reflow soldering processes. Moisture sensitivity level is 1 (Unlimited) for all parts, eliminating bake-out requirements. Packaging format differences (Tape & Reel vs. Cut Tape vs. unspecified) affect procurement and handling but not assembly compatibility.

Q: What is the temperature range consideration for substitution?

A: The SMBJ64CE3/TR13 operates from -65°C to 150°C junction temperature. Both substitute parts operate from -55°C to 150°C. If the application requires operation below -55°C, the original Microchip part is required. For applications within -55°C to 150°C range, all three parts are interchangeable from a temperature specification standpoint.

Q: Are all parts RoHS3 compliant?

A: Yes. SMBJ64CE3/TR13, SMBJ64CA, and SMBJ64CA-13-F are all RoHS3 compliant with MSL rating of 1 (Unlimited). REACH status is Unaffected for all parts, and all are classified as EAR99 for export purposes.
