Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped exclusively based on the matching of essential electrical and mechanical parameters. These key parameters are: Zener voltage (7.5 V), tolerance (±5%), maximum power (≥1.5 W), impedance (3 Ohms), reverse leakage current (5 µA @ 6 V), forward voltage (1.5 V @ 200 mA), surface mount configuration, and package/case (DO-214AA, SMB). Product status must be active, and inventory is considered for availability. Compliance flags are retained as per provided data.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts, 1SMB5922B-13 (Diodes Incorporated) and 1SMB5922BT3G (onsemi), are active and available with significant stock. Both alternatives have matching compliance status including RoHS3 and REACH Unaffected. All products are classified under ECCN: EAR99 and HTSUS: 8541.10.0050. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for substitutes. Electrical and mechanical compatibility is ensured by matching provided key parameters.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for a Zener diode to be substituted in this category?
A1: Substitute Zener diodes must match Zener voltage, tolerance, maximum power rating, impedance, reverse leakage current, forward voltage at specified current, mounting type, and package/case.

Q2: What are the differences in packaging types among these substitute parts?
A2: Main part SMBJ5922B-TP is supplied in bulk packaging, while 1SMB5922B-13 uses cut tape (CT), and 1SMB5922BT3G offers cut tape (CT) and Digi-Reel®. All use the same DO-214AA (SMB) mechanical footprint.

Q3: Is power rating compatibility ensured with the substitute parts?
A3: All substitutes provide a maximum power rating of 3 W, which meets or exceeds the specified 1.5 W of SMBJ5922B-TP.

Q4: Are there differences in operating temperature ranges?
A4: Substitute parts specify an operating temperature range of -65°C ~ 150°C, which encompasses the -55°C ~ 150°C range of the main part.

Q5: Are all substitutes suitable for surface mount applications in DO-214AA (SMB) packages?
A5: Yes, all listed substitute parts are designed for surface mount configuration in the DO-214AA (SMB) package.

Q6: Does compliance status differ among these Zener diodes?
A6: All parts, including the main and substitutes, have REACH Unaffected status and are RoHS3 compliant where specified. No differences in regulatory designations are present in the provided data.
