DZ2S075M0L Zener Diode Equivalent & Substitute Parts

Part Overview

The DZ2S075M0L is a surface mount zener diode manufactured by Panasonic Electronic Components, rated at 7.51 V nominal with 150 mW maximum power dissipation. This component is packaged in SC-79/SOD-523 form factor with SSMini2-F5-B supplier designation. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers. Substitute parts must maintain compatibility with the original electrical specifications and mechanical package requirements to ensure direct replacement capability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2S075M0L is determined by the following critical parameters:

Primary Electrical Criteria:

• Zener voltage nominal value within acceptable circuit tolerance (7.5 V to 7.51 V range)
• Maximum power dissipation rating of 150 mW or greater
• Voltage tolerance specification of ±2.5% or tighter
• Operating temperature range encompassing the original -40°C to 85°C specification

Mechanical & Package Criteria:

• Surface mount packaging in SC-79 or SOD-523 form factor
• Moisture sensitivity level of 1 (Unlimited)
• RoHS compliance status

Compliance & Availability:

• Active product status from manufacturer
• RoHS3 compliance preferred for current procurement
• Adequate inventory availability

The three substitute parts identified (BZT585B7V5T-7, EDZVT2R7.5B, EDZVFHT2R7.5B) meet these substitution criteria with variations in power rating, impedance, and temperature range that do not preclude their use as direct replacements in the original application.

Parameter Comparison

Engineering Selection Recommendations

BZT585B7V5T-7 (Diodes Incorporated)

This substitute offers the highest power rating at 350 mW, providing design margin above the original 150 mW specification. The tighter voltage tolerance of ±2% and lower impedance of 10 Ohms improve circuit performance characteristics. Extended operating temperature range of -65 to 150°C exceeds original specifications. Active product status with ROHS3 compliance and high inventory availability (21,510 units) support immediate procurement. Suitable for applications requiring enhanced thermal performance or higher current handling capacity.

EDZVT2R7.5B (Rohm Semiconductor)

This substitute maintains identical power rating of 150 mW and operating temperature range of -55 to 150°C, which encompasses the original -40 to 85°C specification. Voltage tolerance of ±2% is tighter than the original ±2.5%. Active product status with ROHS3 compliance and extensive inventory (16,677 units) ensures availability. Series designation EDZV indicates automotive-grade qualification pathway. Impedance of 30 Ohms is higher than original but within acceptable substitution parameters. Direct functional equivalent for standard applications.

EDZVFHT2R7.5B (Rohm Semiconductor)

This substitute provides automotive-grade qualification with AEC-Q101 certification, suitable for applications requiring automotive component standards. Maintains 150 mW power rating and ±2.13% voltage tolerance. Impedance of 30 Ohms and reverse leakage of 500 nA @ 4 V are within acceptable ranges. Active product status with ROHS3 compliance and adequate inventory (7,271 units) support procurement. Operating temperature specification of 150°C (TJ) indicates maximum junction temperature without explicit lower bound; verify thermal requirements for applications below 0°C.

All three substitutes are mechanically compatible with the original SC-79/SOD-523 package and maintain MSL 1 (Unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can BZT585B7V5T-7 be used as a direct replacement for DZ2S075M0L?

A: Yes. Both components share identical package designation (SC-79, SOD-523), surface mount configuration, and zener voltage specification within 0.01 V. The BZT585B7V5T-7 provides higher power rating (350 mW vs. 150 mW) and tighter voltage tolerance (±2% vs. ±2.5%), making it functionally compatible. Lower impedance (10 Ohms vs. 20 Ohms) may improve circuit stability in certain applications.

Q: What is the difference between EDZVT2R7.5B and EDZVFHT2R7.5B?

A: Both are Rohm Semiconductor products with identical electrical specifications (7.5 V, 150 mW, ±2% to ±2.13% tolerance). The primary distinction is automotive qualification: EDZVFHT2R7.5B carries AEC-Q101 certification for automotive applications, while EDZVT2R7.5B is standard industrial grade. Operating temperature specification for EDZVFHT2R7.5B is listed as 150°C (TJ) maximum; EDZVT2R7.5B specifies -55 to 150°C range. Select EDZVFHT2R7.5B for automotive designs; EDZVT2R7.5B for general industrial use.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts carry ROHS3 compliance certification. The original DZ2S075M0L is RoHS Compliant. All parts meet current environmental and regulatory requirements for electronic component procurement.

Q: Does the higher power rating of BZT585B7V5T-7 affect circuit compatibility?

A: No. Higher power rating (350 mW vs. 150 mW) indicates greater thermal capacity and does not negatively impact circuit operation. The component will dissipate the same power as the original when operating at identical current levels. The higher rating provides design margin and improved reliability in thermal stress conditions.

Q: What is the significance of impedance differences among the substitutes?

A: Impedance (Zzt) affects dynamic response and noise characteristics. The original DZ2S075M0L specifies 20 Ohms maximum impedance. BZT585B7V5T-7 offers lower impedance (10 Ohms), providing superior high-frequency noise filtering. EDZVT2R7.5B and EDZVFHT2R7.5B specify 30 Ohms, which is higher but remains within acceptable substitution parameters for most applications. Select based on circuit noise filtering requirements.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts use identical SC-79/SOD-523 package with surface mount configuration. PCB footprints, solder pad layouts, and component placement remain unchanged. No PCB redesign is required for substitution.

Q: What is the reverse leakage current significance?

A: Reverse leakage current affects standby power consumption and circuit quiescent current. The original DZ2S075M0L specifies 100 nA @ 5 V. BZT585B7V5T-7 specifies 1 µA @ 5 V (higher leakage), while EDZVT2R7.5B and EDZVFHT2R7.5B specify 500 nA @ 4 V. For applications with strict standby power requirements, EDZVT2R7.5B or EDZVFHT2R7.5B provide lower leakage characteristics closer to the original specification.

Q: Which substitute is recommended for new designs?

A: EDZVT2R7.5B is recommended for new industrial designs due to active status, ROHS3 compliance, extensive inventory, and balanced electrical characteristics. For automotive applications, select EDZVFHT2R7.5B with AEC-Q101 qualification. For applications requiring maximum power margin and lowest impedance, select BZT585B7V5T-7.
