DZ2S02700L Zener Diode Equivalent & Substitute Parts

Part Overview

The DZ2S02700L is a 2.7 V Zener diode manufactured by Panasonic Electronic Components, rated for 150 mW maximum power dissipation in a surface mount SSMini2-F5-B package. This component is classified as discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines. Substitute parts must maintain the core electrical specifications: 2.7 V nominal Zener voltage, ±5% tolerance compatibility, and 150 mW power rating minimum, while accommodating the SC-79/SOD-523 package family.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2S02700L is determined by strict adherence to the following electrical and mechanical parameters:

Primary Matching Criteria:

• Voltage - Zener (Nom): 2.7 V (exact match required)
• Tolerance: ±5% or tighter (±4.07% and ±7.4% are acceptable)
• Power - Max: 150 mW minimum (higher ratings are acceptable for derating applications)
• Mounting Type: Surface Mount (required)
• Package / Case: SC-79 or SOD-523 (compatible package family)

Secondary Compatibility Parameters:

• Impedance (Max): 110 Ohms nominal (100-110 Ohms acceptable)
• Current - Reverse Leakage @ Vr: 120 µA @ 1 V (reference baseline)
• RoHS Compliance: Required for new designs
• Moisture Sensitivity Level: 1 (Unlimited) preferred

All four substitute parts meet the primary matching criteria. Variations in power rating, impedance, and leakage current reflect manufacturing differences across suppliers while maintaining functional equivalence for the 2.7 V Zener application.

Engineering Selection Recommendations

For Direct Replacement (Equivalent Power Rating):

EDZVT2R2.7B (Rohm Semiconductor) is the primary equivalent substitute. This part maintains the 150 mW power rating, 2.7 V nominal Zener voltage, and SC-79/SOD-523 package compatibility. The part is Active in product status with ROHS3 compliance and unlimited moisture sensitivity rating. Operating temperature range of -55°C to 150°C accommodates standard industrial applications.

For Higher Power Dissipation Applications:

BZX585-C2V7,115 (NXP USA Inc.) provides 300 mW power rating with identical 2.7 V Zener voltage and ±5% tolerance. This part is Active in product status with extended operating temperature range (-65°C to 150°C). The doubled power rating enables thermal derating in high-current applications while maintaining package compatibility.

SZMM5Z2V7T1G (onsemi) offers 500 mW power rating with AEC-Q101 automotive qualification. This part is suitable for applications requiring significant thermal margin or automotive-grade reliability. The ±7.4% tolerance remains within acceptable substitution parameters for 2.7 V Zener applications.

For Automotive Applications:

SZMM5Z2V7T1G (onsemi) carries AEC-Q101 qualification and automotive-grade designation, meeting requirements for automotive circuit protection and voltage regulation.

EDZVFHT2R2.7B (Rohm Semiconductor) carries AEC-Q101 qualification with automotive-grade designation. However, this part is classified as Not For New Designs and should be avoided for new product development.

For New Product Designs:

Select from Active product status parts only: EDZVT2R2.7B, BZX585-C2V7,115, or SZMM5Z2V7T1G. All three parts provide ROHS3 compliance and unlimited moisture sensitivity rating suitable for modern manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can BZX585-C2V7,115 replace DZ2S02700L directly in existing designs?

A: Yes. BZX585-C2V7,115 maintains the 2.7 V nominal Zener voltage, ±5% tolerance, and SC-79/SOD-523 package compatibility. The 300 mW power rating exceeds the 150 mW requirement, allowing operation at lower junction temperatures. No circuit modifications are required.

Q: What is the difference between EDZVT2R2.7B and EDZVFHT2R2.7B?

A: Both parts are 2.7 V, 150 mW Zener diodes in EMD2 packages. EDZVFHT2R2.7B is automotive-qualified (AEC-Q101) but classified as Not For New Designs. EDZVT2R2.7B is Active in product status and recommended for new designs. Electrical specifications are equivalent.

Q: Why does SZMM5Z2V7T1G have a ±7.4% tolerance instead of ±5%?

A: Tolerance variation reflects manufacturing process differences across suppliers. The ±7.4% tolerance remains within acceptable substitution parameters for 2.7 V Zener applications. At 2.7 V nominal, ±7.4% tolerance yields a range of 2.50 V to 2.90 V, suitable for voltage regulation and protection circuits.

Q: Are all substitute parts in the same package?

A: All substitute parts use SC-79 or SOD-523 package designations, which are mechanically and electrically compatible. Supplier device packages vary (SSMini2-F5-B, SOD-523, EMD2) but represent the same physical form factor suitable for surface mount assembly.

Q: Which substitute part has the lowest reverse leakage current?

A: BZX585-C2V7,115 and SZMM5Z2V7T1G both specify 20 µA @ 1 V reverse leakage current, compared to 120 µA @ 1 V for the original DZ2S02700L. Lower leakage current reduces standby power consumption in battery-powered applications.

Q: Can I use EDZVFHT2R2.7B in new product designs?

A: EDZVFHT2R2.7B is classified as Not For New Designs. For new product development, select from Active status parts: EDZVT2R2.7B, BZX585-C2V7,115, or SZMM5Z2V7T1G.

Q: What is the operating temperature range for each substitute?

A: EDZVT2R2.7B operates -55°C to 150°C. BZX585-C2V7,115 operates -65°C to 150°C. SZMM5Z2V7T1G operates -65°C to 150°C. EDZVFHT2R2.7B specifies 150°C maximum junction temperature. Select based on application temperature requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. DZ2S02700L is RoHS Compliant. All substitute parts are ROHS3 Compliant, meeting current environmental regulations for new manufacturing.
