Equivalent & Substitute Parts for SMBJ5365A/TR13

Part Overview

The SMBJ5365A/TR13 is a 36 V 5 W Zener diode intended for surface mounting in electronic assemblies. This device features a Zener voltage of 36 V ±10%, a maximum power dissipation of 5 W, and is supplied in a DO-214AA (SMBJ) package. The part is active and available in tape & reel packaging, with a specified reverse leakage current and voltage forward drop. Finding alternative models is necessary when considering inventory requirements, regulatory compliance (such as RoHS status), or sourcing flexibility.

Substitute Part Grouping Explanation

Substitution is determined strictly by matching essential electrical and mechanical parameters for Zener diodes, including:

Zener voltage (Vz)
Voltage tolerance
Maximum power dissipation
Impedance (Zzt)
Reverse leakage current at specified voltage
Forward voltage at measuring current
Operating temperature range
Package, mounting type, and form factor
Compliance status (RoHS, REACH, MSL)

Only devices matching these key parameters within the bounds specified are grouped as suitable substitutes.

Engineering Selection Recommendations

Selection among the above Zener diodes should be determined by product status (all parts listed are active), environmental compliance (RoHS and REACH status), and moisture sensitivity level. RoHS status differs between the original SMBJ5365A/TR13 (RoHS non-compliant) and substitute parts (ROHS3 Compliant). All parts have MSL 1 (Unlimited) and are listed as REACH Unaffected.

Frequently Asked Questions (FAQ)

Q1: What parameters are essential when selecting a Zener diode substitute?
A1: Essential parameters for Zener diode substitution include Zener voltage, tolerance, power rating, impedance, reverse leakage current, forward voltage at specified current, operating temperature range, package, mounting type, and compliance status.

Q2: Are the substitute Zener diodes compatible with the same surface mount footprint?
A2: All compared parts share the DO-214AA (SMB) case and surface mount style, supporting drop-in compatibility from a mechanical perspective.

Q3: How does RoHS compliance affect selection?
A3: The SMBJ5365A/TR13 is RoHS non-compliant, while substitute parts are ROHS3 Compliant. Selection may depend on environmental and regulatory requirements of the end application.

Q4: Can the substitute diodes be used in the same temperature range?
A4: All listed parts support an operating temperature range of -65°C to 150°C.

Q5: Are there differences in power handling between substitutes and the main part?
A5: Substitute parts have lower maximum power ratings (550 mW or 3 W), whereas the SMBJ5365A/TR13 is rated for 5 W. Review application power requirements before selection.

Q6: Do all substitutions have the same electrical parameters?
A6: There are differences in tolerance, power rating, impedance, reverse leakage, and forward voltage. These must be matched to application needs according to specified values.
