Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2S30000L is determined by alignment of the following critical parameters:

Primary Matching Criteria:

• Zener voltage nominal value: 30 V (tolerance range 28.5 V to 31.5 V for ±5% specification)
• Package compatibility: SC-79 or SOD-523 surface mount packages
• Mounting type: Surface mount technology
• RoHS compliance status

Secondary Compatibility Factors:

• Power dissipation rating: Minimum 150 mW (equal or greater)
• Impedance characteristics: Maximum 160 Ohms or lower
• Reverse leakage current: 50 nA or lower at specified voltage
• Moisture sensitivity: MSL 1 classification

The substitute parts identified meet the primary matching criteria and maintain functional equivalence within the specified electrical parameters. Both alternatives are available in active production status with improved or equivalent specifications compared to the discontinued DZ2S30000L.

Parameter Comparison

Engineering Selection Recommendations

BZT585B30T-7 (Diodes Incorporated)

This substitute provides superior electrical performance characteristics. The zener voltage matches the primary specification at 30 V with improved tolerance of ±2% compared to the original ±5%. Power dissipation capability is increased to 350 mW, providing additional design margin. Impedance is reduced to 80 Ohms, delivering improved voltage regulation stability. The part maintains active production status with ROHS3 compliance and unlimited moisture sensitivity classification. This option is suitable for applications requiring enhanced performance specifications and long-term supply availability.

EDZVFHT2R30B (Rohm Semiconductor)

This substitute maintains electrical parity with the original DZ2S30000L. The zener voltage is 29.94 V with ±2.5% tolerance, remaining within the acceptable range. Power dissipation is matched at 150 mW. The part carries AEC-Q101 automotive qualification and is designated for automotive-grade applications. Active production status and ROHS3 compliance ensure supply continuity. This option is appropriate for applications requiring automotive-grade components or where impedance characteristics of 200 Ohms are acceptable.

Both substitutes are available in active production with improved compliance certifications and supply availability compared to the discontinued DZ2S30000L.

Frequently Asked Questions (FAQ)

Q: Can the BZT585B30T-7 be used as a direct replacement for the DZ2S30000L?

A: Yes. Both components share identical zener voltage (30 V), package type (SOD-523), and mounting configuration (surface mount). The BZT585B30T-7 provides equivalent or superior electrical performance with improved tolerance (±2% vs. ±5%) and higher power rating (350 mW vs. 150 mW).

Q: What is the difference between the two substitute parts?

A: The BZT585B30T-7 offers higher power dissipation (350 mW) and lower impedance (80 Ohms), providing enhanced regulation characteristics. The EDZVFHT2R30B maintains the original 150 mW power rating and includes automotive-grade qualification (AEC-Q101). Selection depends on application requirements for power handling and automotive compliance.

Q: Are both substitutes available in the same package as the original part?

A: Yes. All three parts use SC-79 or SOD-523 surface mount packages. The BZT585B30T-7 is supplied in Tape & Reel packaging, while the EDZVFHT2R30B is available in Cut Tape and Digi-Reel formats. Both are compatible with standard surface mount assembly processes.

Q: Does the zener voltage tolerance difference affect circuit operation?

A: The original DZ2S30000L specifies ±5% tolerance (28.5 V to 31.5 V range). The BZT585B30T-7 provides ±2% tolerance (29.4 V to 30.6 V), and the EDZVFHT2R30B provides ±2.5% tolerance (29.18 V to 30.70 V). Both substitutes maintain operation within the original tolerance band while offering tighter specifications.

Q: What is the significance of the impedance parameter in zener diode selection?

A: Impedance (Zzt) affects voltage regulation quality. Lower impedance values provide better voltage stability under load changes. The BZT585B30T-7 at 80 Ohms offers superior regulation compared to the original 160 Ohms. The EDZVFHT2R30B at 200 Ohms requires circuit evaluation if regulation performance is critical.

Q: Are there any moisture sensitivity concerns with these substitutes?

A: All three parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.

Q: Which substitute is recommended for new designs?

A: Selection is based on application requirements. For general-purpose voltage regulation with improved performance, the BZT585B30T-7 is suitable. For automotive applications or where the original 150 mW specification is sufficient, the EDZVFHT2R30B is appropriate. Both are in active production with long-term availability.
