VDZT2R36B Equivalent & Substitute Zener Diodes Reference

Part Overview

The VDZT2R36B is a surface-mount Zener diode manufactured by Rohm Semiconductor, designed for voltage regulation and protection applications at 36 V Zener voltage and 100 mW maximum power dissipation. Its electrical and mechanical characteristics include a 300 Ohm maximum impedance, 100 nA maximum reverse leakage at 27 V, and a VMD2 (SOD-723) package. This product is classified as obsolete, making the identification of suitable substitute parts essential for ongoing designs, repairs, and manufacturing continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution between VDZT2R36B and other Zener diodes is determined strictly by the match of key parameters, including Zener voltage (36 V nominal), maximum power dissipation (100 mW), maximum impedance (300 Ohms), maximum reverse leakage current at specified reverse voltage (100 nA @ 27 V), mounting type (surface mount), RoHS compliance, MSL classification, and REACH status. Only parts with equivalent electrical characteristics and compliant surface-mount packaging are listed as substitutes.

Engineering Selection Recommendations

Selection of CDZVT2R36B as a substitute for VDZT2R36B is based strictly on the product status of the main part (Obsolete) and the maintained compliance with ROHS3 and REACH. Both parts are classified as MSL 1 (Unlimited), ensuring identical moisture sensitivity profiles for surface-mount processes. The substitute is active and available in inventory, meeting current sourcing requirements.

Frequently Asked Questions (FAQ)

Q1: What are the mandatory parameters when selecting an equivalent Zener diode?
A1: Mandatory parameters include Zener voltage, power dissipation, impedance, maximum reverse leakage at a defined test voltage, mounting type, and relevant compliance standards.

Q2: Does the package difference between VMD2 (SOD-723) and VMN2M (SOD-923) affect substitution?
A2: Package and supplier device package type are key considerations for PCB design and mechanical compatibility. Ensure compatibility with existing PCB layouts due to potential footprint variations.

Q3: Is the electrical performance of the CDZVT2R36B fully equivalent to the VDZT2R36B?
A3: According to supplied data, key electrical parameters (Zener voltage, power, impedance, and leakage) are equivalent between the two parts.

Q4: Are both parts RoHS and REACH compliant?
A4: Both VDZT2R36B and CDZVT2R36B are ROHS3 compliant and REACH unaffected, supporting use in regulated applications.

Q5: How does the product status impact part selection?
A5: VDZT2R36B is obsolete; therefore, active parts such as CDZVT2R36B are required for new builds or maintenance. All selection must be based on criteria provided.
