DZ2S036M0L Zener Diode Equivalent & Substitute Parts

Part Overview

The DZ2S036M0L is a 3.6 V, 150 mW surface mount zener diode manufactured by Panasonic Electronic Components in the SC-79/SOD-523 package. This component is classified as discontinued at DiGi Electronics, creating a requirement to identify functionally equivalent alternatives from active product lines. The part operates with a nominal zener voltage of 3.6 V and a maximum power dissipation of 150 mW, making it suitable for voltage regulation and protection applications in low-power circuits. Equivalent substitutes must maintain identical electrical specifications within acceptable tolerance ranges and support the same surface mount packaging format.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2S036M0L is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Nominal zener voltage of 3.6 V
• Maximum power dissipation of 150 mW
• Reverse leakage current of 10 µA @ 1 V
• Forward voltage of 1 V @ 10 mA

Physical & Packaging Requirements:

• Surface mount technology
• SC-79/SOD-523 package format
• Moisture sensitivity level 1 (unlimited)

Compliance & Environmental:

• RoHS compliance status
• EAR99 export classification
• HTSUS code 8541.10.0050

The substitute parts identified (EDZVFHT2R3.6B and EDZVT2R3.6B) maintain all critical electrical parameters within acceptable tolerance ranges. Both alternatives are manufactured by Rohm Semiconductor in the EMD2 supplier package, which is physically and electrically compatible with the original SC-79/SOD-523 format. Tolerance variations (±3.4% and ±3% respectively) remain within acceptable engineering margins for zener diode applications. Impedance specifications (100 Ohms maximum) are superior to the original specification (130 Ohms maximum), providing improved performance characteristics.

Engineering Selection Recommendations

EDZVT2R3.6B (Primary Substitute)

The EDZVT2R3.6B is the preferred substitute for the DZ2S036M0L. This part maintains active product status with high inventory availability (37,300 pcs), ensuring long-term supply continuity. The component operates across an extended temperature range of -55°C to 150°C, providing broader environmental compatibility than the original part. Rohm's EDZV series classification and ROHS3 compliance status exceed the original RoHS specification. The impedance specification of 100 Ohms maximum represents an improvement over the original 130 Ohms maximum, resulting in superior voltage regulation characteristics. Tolerance of ±3% is acceptable for standard zener diode applications.

EDZVFHT2R3.6B (Secondary Substitute)

The EDZVFHT2R3.6B serves as an alternative substitute with automotive-grade qualification (AEC-Q101) and a maximum operating temperature of 150°C. This part is suitable for applications requiring automotive-level reliability and traceability. Inventory availability is lower (8,935 pcs) compared to the primary substitute. The tolerance specification of ±3.4% remains within acceptable engineering margins. Selection of this part is appropriate when automotive qualification requirements are specified in the application.

Both substitutes are physically compatible with the original SC-79/SOD-523 package format and support identical electrical functionality. The choice between primary and secondary substitutes depends on application-specific requirements regarding temperature range and automotive qualification status.

Frequently Asked Questions (FAQ)

Q: Can EDZVT2R3.6B and EDZVFHT2R3.6B be used interchangeably with DZ2S036M0L?

A: Both Rohm parts are electrically and physically compatible with the DZ2S036M0L. The primary differences are product status (active vs. discontinued), temperature operating range, and automotive qualification. Selection depends on application requirements. EDZVT2R3.6B is recommended for general applications due to extended temperature range and higher inventory availability. EDZVFHT2R3.6B is specified when automotive-grade qualification is required.

Q: What is the impact of tolerance differences between the original and substitute parts?

A: The DZ2S036M0L specifies ±2.5% tolerance, while EDZVT2R3.6B specifies ±3% and EDZVFHT2R3.6B specifies ±3.4%. These tolerance variations are within acceptable ranges for zener diode voltage regulation applications. The nominal zener voltage of 3.6 V remains constant across all three parts. Applications with strict voltage tolerance requirements should evaluate the specific tolerance band impact on circuit performance.

Q: Are the package formats identical between the original and substitute parts?

A: Yes. All three parts use the SC-79/SOD-523 package format with surface mount technology. The Rohm parts are supplied in EMD2 packaging, which is physically and electrically equivalent to the original SSMini2-F5-B format. No PCB layout modifications are required for substitution.

Q: What is the significance of the impedance specification difference?

A: The DZ2S036M0L specifies a maximum impedance of 130 Ohms, while both Rohm substitutes specify 100 Ohms maximum. Lower impedance provides improved voltage regulation performance and reduced output impedance in voltage regulation circuits. This represents a performance improvement over the original specification.

Q: Are there any compliance or regulatory differences between the parts?

A: The original DZ2S036M0L is RoHS Compliant. Both Rohm substitutes are ROHS3 Compliant, representing an enhanced compliance status. EDZVFHT2R3.6B includes AEC-Q101 automotive qualification and REACH Unaffected status. All three parts share the same EAR99 export classification and HTSUS code 8541.10.0050.

Q: What is the moisture sensitivity level, and does it affect handling?

A: All three parts specify Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage, handling, or assembly. Standard PCB assembly processes are applicable without additional moisture management procedures.

Q: Why is the DZ2S036M0L discontinued, and what is the supply outlook for substitutes?

A: The DZ2S036M0L is discontinued at DiGi Electronics, indicating end-of-life status for the original product. Both Rohm substitutes maintain active product status with substantial inventory availability. EDZVT2R3.6B has 37,300 pcs in stock, ensuring reliable long-term supply for new designs and production requirements.
