Substitute Part Grouping Explanation

Substitute parts for the 1SMB5926B-13 are classified based on electrical parameter equivalence and mechanical compatibility. All identified substitutes maintain the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Zener (Nom): 11 V
• Tolerance: ±5%
• Power - Max: 3 W
• Impedance (Max): 5.5 Ohms
• Current - Reverse Leakage @ Vr: 1 µA @ 8.4 V
• Voltage - Forward (Vf) (Max) @ If: 1.5 V @ 200 mA

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: DO-214AA, SMB
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitutes are grouped into two categories: MFR Recommended (manufacturer-recommended alternative) and Parametric Equivalents (parts meeting all electrical and mechanical specifications). Operating temperature range variations are noted where applicable but do not preclude substitution for standard industrial applications within the overlapping temperature envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (1SMB5926B-13): The 1SMB5926B-13 from Diodes Incorporated is the primary part specification. It is Active in product status, RoHS3 compliant, and available in standard Tape & Reel packaging. This part is suitable for general industrial and commercial applications requiring 11 V Zener regulation within the -65°C to 150°C operating range.

MFR Recommended Substitute (3SMBJ5926B-TP): The 3SMBJ5926B-TP from Micro Commercial Co is the manufacturer-recommended alternative. It meets all electrical specifications and is packaged identically in Tape & Reel format. The operating temperature range is -55°C to 150°C, which is suitable for applications not requiring the extended low-temperature performance of -65°C. This part is Active in product status and RoHS3 compliant.

Parametric Equivalents (1SMB5926BT3G and SZ1SMB5926BT3G): Both onsemi parts (1SMB5926BT3G and SZ1SMB5926BT3G) are parametric equivalents meeting all electrical and mechanical specifications. The 1SMB5926BT3G is available in Cut Tape and Digi-Reel packaging, while the SZ1SMB5926BT3G is supplied in Tape & Reel format. The SZ1SMB5926BT3G carries Automotive grade qualification and AEC-Q101 certification, making it suitable for automotive and high-reliability applications. Both onsemi parts maintain the full -65°C to 150°C operating temperature range.

Selection Basis:

• All substitutes are Active products with RoHS3 compliance
• Electrical parameters are identical across all parts
• Mechanical compatibility is confirmed for all substitutes
• Operating temperature range overlap supports direct substitution for standard industrial applications
• Automotive-qualified variant (SZ1SMB5926BT3G) is available for applications requiring AEC-Q101 certification

Frequently Asked Questions (FAQ)

Q: Can the 3SMBJ5926B-TP be used as a direct replacement for the 1SMB5926B-13?

A: Yes. The 3SMBJ5926B-TP meets all electrical specifications (11 V nominal, ±5% tolerance, 3 W power, 5.5 Ohms impedance) and is mechanically compatible in the DO-214AA (SMB) package. The operating temperature range difference (-55°C to 150°C versus -65°C to 150°C) does not affect substitution for applications operating within the overlapping range of -55°C to 150°C.

Q: What is the difference between the onsemi 1SMB5926BT3G and SZ1SMB5926BT3G?

A: Both parts are electrically and mechanically identical with identical operating temperature ranges (-65°C to 150°C). The primary difference is that the SZ1SMB5926BT3G carries Automotive grade qualification and AEC-Q101 certification, making it suitable for automotive applications. The 1SMB5926BT3G is supplied in Cut Tape and Digi-Reel packaging, while the SZ1SMB5926BT3G is supplied in Tape & Reel format.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitutes (3SMBJ5926B-TP, 1SMB5926BT3G, and SZ1SMB5926BT3G) are RoHS3 compliant, matching the compliance status of the primary part 1SMB5926B-13.

Q: What packaging options are available for these Zener diodes?

A: The 1SMB5926B-13 and 3SMBJ5926B-TP are supplied in Tape & Reel (TR) format. The onsemi 1SMB5926BT3G is available in Cut Tape (CT) and Digi-Reel® format. The onsemi SZ1SMB5926BT3G is supplied in Tape & Reel (TR) format. All parts use the same DO-214AA (SMB) physical package.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes. All substitute parts share identical mechanical specifications (DO-214AA SMB package, Surface Mount mounting type, and Moisture Sensitivity Level 1). Tape & Reel packaged parts (1SMB5926B-13, 3SMBJ5926B-TP, SZ1SMB5926BT3G) are directly compatible with standard pick-and-place equipment. The Cut Tape variant (1SMB5926BT3G) requires compatible tape handling equipment.

Q: Which part should be selected for automotive applications?

A: The SZ1SMB5926BT3G from onsemi is qualified for automotive applications with AEC-Q101 certification. This part meets all electrical and mechanical specifications while providing automotive-grade reliability assurance.
