Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ36AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Reverse standoff voltage of 36V, breakdown minimum of 40V, and maximum clamping voltage of 58.1V
• Current Handling: Peak pulse current of 10.3A at 10/1000µs pulse duration
• Power Dissipation: 600W peak pulse power rating
• Package: DO-214AA (SMB) surface mount package
• Electrical Type: Unidirectional Zener TVS diode with single channel
• Temperature Range: Operating range of -55°C to 150°C (TJ)
• Compliance: Automotive grade with AEC-Q101 qualification, ROHS3 compliance, and REACH unaffected status

The substitute part SMBJ36AHM3_B/I matches all electrical and mechanical parameters while differing only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The SMBJ36AHM3_B/I is the direct substitute for the obsolete SMBJ36AHM3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical specifications, thermal performance, and compliance certifications.

The primary distinction is product status: SMBJ36AHM3_A/I is Obsolete, while SMBJ36AHM3_B/I is Active. The Active status of SMBJ36AHM3_B/I ensures ongoing availability, manufacturing support, and compliance with current quality standards. Both parts carry Automotive grade qualification and AEC-Q101 certification, confirming suitability for automotive and industrial telecom applications.

The packaging format difference (standard vs. Tape & Reel) reflects supply chain configuration and does not affect electrical or mechanical compatibility. Selection between these formats depends on assembly process requirements and procurement volume.

Frequently Asked Questions (FAQ)

Q: Can SMBJ36AHM3_B/I be used as a direct replacement for SMBJ36AHM3_A/I?

A: Yes. SMBJ36AHM3_B/I is electrically and mechanically identical to SMBJ36AHM3_A/I across all specified parameters. The substitute part maintains the same 36V reverse standoff voltage, 58.1V clamping voltage, 10.3A peak pulse current, 600W power rating, DO-214AA package, and operating temperature range. Both parts are Automotive grade with AEC-Q101 qualification.

Q: What is the difference between SMBJ36AHM3_A/I and SMBJ36AHM3_B/I?

A: The primary differences are product status and packaging format. SMBJ36AHM3_A/I is Obsolete with standard packaging, while SMBJ36AHM3_B/I is Active with Tape & Reel (TR) packaging. All electrical and mechanical specifications are identical.

Q: Why is SMBJ36AHM3_A/I marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. SMBJ36AHM3_B/I, the Active equivalent, is the recommended source for new designs and ongoing production requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both SMBJ36AHM3_A/I and SMBJ36AHM3_B/I are ROHS3 compliant, REACH unaffected, and carry AEC-Q101 automotive qualification. Compliance profiles are identical.

Q: Does the Tape & Reel packaging of SMBJ36AHM3_B/I affect circuit performance?

A: No. Tape & Reel is a supply format for automated assembly processes. It does not alter electrical performance, thermal characteristics, or mechanical fit. The component itself remains identical.

Q: What is the base product number for these parts?

A: The base product number is SMBJ36, which identifies the 36V voltage rating within the TransZorb® TVS diode series. Suffix variations (such as AHM3_A/I and AHM3_B/I) indicate packaging and qualification configurations.
