SMBJ5353A/TR13 Zener Diode – Equivalent & Substitute Parts Reference

Part Overview

The SMBJ5353A/TR13 from Microchip Technology is a Zener diode categorized under Diodes, Zener; provided in a surface mount DO-214AA (SMBJ) package. It features a nominal Zener voltage of 16 V, maximum power dissipation of 5 W, ±10% tolerance, and maximum Zener impedance of 2.5 Ohms. This component is actively supplied, but RoHS non-compliance may necessitate identifying alternative parts for regions or applications with strict environmental requirements. Finding alternatives is also important for inventory management and supply chain continuity.

Substitute Part Grouping Explanation

Substitute or equivalent Zener diodes are identified by matching these mandatory parameters: Zener voltage (16 V), package/case (DO-214AA, SMB), mounting type (Surface Mount), and temperature range (-65°C ~ 150°C). Additional comparison parameters include tolerance, maximum power dissipation, Zener impedance, reverse leakage current, forward voltage, RoHS status, and MSL rating. Only parts meeting these specific values or stricter criteria for the intended application are considered substitutes.

Engineering Selection Recommendations

Based on product status, RoHS compliance, and provided certifications, SMBJ5353A/TR13 is RoHS non-compliant, while 1SMB5930BT3G is ROHS3 compliant and REACH unaffected. For designs requiring RoHS compliance, use of 1SMB5930BT3G is consistent with regulatory needs. Moisture Sensitivity Level (MSL) of 1 (Unlimited) is present for both Zener diodes. Both components are listed as active, supporting ongoing product availability.

Frequently Asked Questions (FAQ)

Q1: What makes a Zener diode a valid substitute in this context?
A: A valid substitute must match or have stricter parameters for voltage - Zener (nominal), package/case type (DO-214AA, SMB), mounting type, and operating temperature range. Additional selection is based on tolerance, power rating, impedance, reverse leakage, and forward voltage as provided.

Q2: Are there compliance differences between the main and substitute Zener diodes?
A: SMBJ5353A/TR13 is RoHS non-compliant. 1SMB5930BT3G is ROHS3 compliant, and both are REACH unaffected. MSL is 1 (Unlimited) for both.

Q3: Are the package and form factor identical for both parts?
A: Yes, both SMBJ5353A/TR13 and 1SMB5930BT3G use the DO-214AA (SMB) surface mount package.

Q4: What Zener voltage is supported by these products?
A: Both parts support a nominal Zener voltage of 16 V.

Q5: Which part should be selected for RoHS-compliant applications?
A: 1SMB5930BT3G should be selected for RoHS-compliant requirements, as per the provided RoHS status.

Q6: Do both Zener diodes have similar operating temperature ranges?
A: Both have an operating temperature range of -65°C to 150°C.
