Equivalent & Substitute Parts for EDZVT2R24B Zener Diode

Part Overview

The EDZVT2R24B is a Zener diode from Rohm Semiconductor, designed for voltage regulation applications. It features a nominal Zener voltage of 24 V, a maximum power dissipation of 150 mW, a tight tolerance of ±2%, and is housed in an SC-79, SOD-523 surface mount package (EMD2). This device is RoHS3 compliant, has a low reverse leakage current, and an operating temperature range suitable for various environments. As supply chain dynamics and inventory availability can change, it is necessary to identify compatible substitute parts to maintain design continuity and production output.

Engineering Selection Recommendations

All substitute parts provided are active unless otherwise noted. Discontinued parts should be selected only when sufficient verified inventory is available. Every substitute listed is RoHS compliant and carries a moisture sensitivity level of 1 (Unlimited), matching the environmental compliance of the reference part. All substitute part numbers conform to the standard packaging and mounting type requirements. Qualification or grade levels (e.g. AEC-Q100) should be referenced when documented per the input; otherwise, selection must be based on the explicit inventory and status fields provided.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical when selecting a Zener diode substitute for EDZVT2R24B?
A1: The critical parameters are Zener voltage (24 V), tolerance, maximum power dissipation, impedance, reverse leakage current, mounting type (Surface Mount), package/case (SC-79, SOD-523), RoHS compliance, and moisture sensitivity level.

Q2: Are all substitute parts compatible with the same footprint and package type as EDZVT2R24B?
A2: Yes. All listed substitutes use SC-79 or SOD-523 surface-mount packaging, matching the main part's mechanical footprint.

Q3: Does tolerance variation affect substitution?
A3: Tolerance directly affects voltage regulation precision. Substitute parts with ±2% (BZX585-B24,115) replicate the main part's range. Wider tolerance (CMOZ24V TR PBFREE at ±5%) should only be chosen if design permits.

Q4: Can higher power rated substitutes be used?
A4: Substitute diodes with higher maximum power (e.g., 300 mW) are compatible as long as other key parameters are matched, per provided specifications.

Q5: What compliance or certification differences exist among substitutes?
A5: All substitutes are RoHS compliant with equivalent MSL ratings. Automotive grade or additional qualifications are detailed per part where applicable.

Q6: Is discontinued status a selection concern?
A6: Discontinued substitute parts (DZ2S240M0L) should only be utilized when inventory is available and lifecycle status matches application requirements. Active status is preferred for new designs.
