Equivalent & Substitute Parts Reference: SMBJ5932A/TR13

Part Overview

The SMBJ5932A/TR13 from Microchip Technology is a Zener diode in the DO-214AA (SMBJ) surface mount package, rated for 20 V nominal Zener voltage and 2 W maximum power dissipation. It features ±10% tolerance, 14 Ohms maximum impedance, and 1 µA maximum reverse leakage at 15.2 V. The component status is Active; it is available in Tape & Reel packaging. Alternative or substitute models are sometimes necessary due to inventory requirements, compliance needs, or preferred tolerances and power ratings within a project.

Substitute Part Grouping Explanation

Substitute parts are grouped according to the following key parameters: Zener voltage (20 V), maximum power dissipation (>=550 mW), tolerance (±5% or ±10%), maximum impedance (14 Ohms), maximum reverse leakage current (1 µA @ 15.2 V), maximum forward voltage (<=1.5 V @ 200 mA), operating temperature (-65°C ~ 150°C), mounting type (Surface Mount), and package (DO-214AA, SMB). Only components matching these criteria—especially voltage, package, mounting type, and electrical characteristics—are considered direct substitutes.

Engineering Selection Recommendations

When selecting a substitute for the SMBJ5932A/TR13 Zener diode, note the product status ("Active") for main and substitute parts. Substitute models 1SMB5932B-13, 1SMB5932BT3G, and SZ1SMB5932BT3G are all "Active." For compliance requirements, the substitute parts are ROHS3 Compliant, while the SMBJ5932A/TR13 is RoHS non-compliant. Moisture Sensitivity Level (MSL) and REACH status are consistent across all parts (MSL 1, REACH Unaffected). For automotive and high-reliability applications, SZ1SMB5932BT3G is specified with AEC-Q101 qualification.

Frequently Asked Questions (FAQ)

Q1: Which key parameters must match for a direct Zener diode substitute?
A1: Zener voltage, tolerance, power rating, impedance, reverse leakage, forward voltage, package/case, mounting type, and operating temperature range are the required matching criteria.

Q2: Can I substitute a Zener diode with a different tolerance or power rating?
A2: Substitute parts listed feature tolerance (±5%) and power ratings between 550 mW and 3 W. Ensure these meet circuit specifications, as they differ from the original ±10% tolerance and 2 W power rating.

Q3: Are package and mounting type critical for substitution?
A3: Yes. All listed substitutes are DO-214AA, SMB surface mount package Zener diodes, maintaining physical compatibility.

Q4: Is RoHS or compliance status important for substitute selection?
A4: Substitute options 1SMB5932B-13, 1SMB5932BT3G, and SZ1SMB5932BT3G are ROHS3 Compliant, unlike the main part. Verify compliance requirements for the application.

Q5: Do the substitute diodes support the same operating temperature range?
A5: Yes. All candidate parts operate between -65°C and 150°C.

Q6: Should applications needing automotive qualification choose a specific substitute?
A6: SZ1SMB5932BT3G possesses AEC-Q101 automotive qualification per input parameters. Select as required for automotive-grade circuits.
