Key Parameters

Substitute Part Grouping Explanation

Substitute parts for SMBJ5935B-TP are identified by matching the following allowed electrical and mechanical parameters:

• Zener voltage (27 V nominal)
• Tolerance (±5%)
• Power rating (≥1.5 W)
• Maximum impedance (23 Ohms)
• Maximum reverse leakage current at specified test voltage
• Forward voltage characteristics
• Package compatibility (DO-214AA/SMB)
• Mounting type (surface mount)
• Operating temperature range
• Status (active)
• Compliance data if available (REACH, RoHS, MSL, ECCN)

Parts categorized as “Upgrade,” “Similar,” or “Parametric Equivalent” maintain these criteria as per provided data.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts for SMBJ5935B-TP are active and fulfill compliance standards as indicated (RoHS, REACH). Differences in power ratings and specific supplier device package notations must be matched with application requirements. MSL and ECCN data are consistent with standard electronic component distribution. Where parts are automotive qualified or possess a higher or lower power rating than the main part, this must align with project design requirements, as per presented specifications.

Frequently Asked Questions (FAQ)

Q1: Which electrical parameters are mandatory for Zener diode substitution?
A1: Voltage - Zener (Nominal), tolerance, power rating, impedance, and maximum reverse leakage at the reference voltage.

Q2: Is the mechanical package critical for substitution?
A2: Yes, the substitute must have the same DO-214AA (SMB) package and surface mount configuration.

Q3: Can a part with higher power rating substitute the main part?
A3: Yes, as per provided information, higher power rating is allowed; however, all other parameters must match.

Q4: Are compliance and qualification factors considered?
A4: Yes, compliance data such as RoHS, REACH, MSL, and automotive qualification are included within the substitution criteria where available.

Q5: Can reverse leakage differences affect part selection?
A5: Only within the specified parameter range. Parts with higher reverse leakage (provided value) are included as options per the supplied data.

Q6: What if the voltage forward parameter is omitted from the substitute?
A6: Only substitutes with explicitly matching parameters are compared for this criterion. If omitted, comparison is limited to presented parameters.

Q7: Does packaging format affect electrical equivalence?
A7: Packaging (Bulk vs Tape & Reel) does not affect substitution eligibility in an electrical or mechanical sense if device form and package code match.
