DZ2W36000L Equivalent & Substitute Parts

Part Overview

The DZ2W36000L is a 36 V, 1 W Zener diode manufactured by Panasonic Electronic Components in the SOD-123F surface mount package. This component is designed for voltage regulation and protection applications requiring precise 36 V reference voltage with ±5% tolerance. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers. Substitute parts must maintain compatibility with the original electrical specifications and surface mount package requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2W36000L is determined by the following critical parameters:

Primary Substitution Criteria:

• Zener voltage nominal value: 36 V
• Maximum power dissipation: 1 W
• Package type: SOD-123F surface mount
• Impedance (Max): 30 Ohms
• Reverse leakage current: 10 µA @ 28.8 V
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Factors:

• Voltage tolerance range
• Forward voltage characteristics
• Operating temperature range
• RoHS compliance status

The substitute parts identified maintain the core electrical parameters required for direct functional replacement. Variations in voltage tolerance, forward voltage, and operating temperature do not preclude substitution when the primary criteria are satisfied and the application requirements permit such variations.

Engineering Selection Recommendations

CRZ36(TE85L,Q,M) - Toshiba Semiconductor and Storage

This substitute maintains the 36 V nominal zener voltage and 30 Ohm impedance specification. Power dissipation is reduced to 700 mW, which represents a limitation for applications requiring full 1 W operation. The ±10% tolerance is wider than the original ±5% specification. This part is suitable for applications where power dissipation does not exceed 700 mW and voltage tolerance of ±10% is acceptable. Product status is active with ROHS3 compliance.

KDZVTR36B - Rohm Semiconductor

This substitute provides 1 W power dissipation matching the original specification. The zener voltage is specified at 38 V, representing a 2 V deviation from the 36 V nominal. Tolerance information is not provided in the available data. This part is suitable for applications where the 38 V zener voltage is compatible with circuit requirements. Product status is active with ROHS3 compliance and REACH unaffected status. Automotive grade qualification (AEC-Q101) is available in the KDZVTFTR36B variant.

KDZVTFTR36B - Rohm Semiconductor

This substitute provides 1 W power dissipation and maintains the ±5.56% tolerance specification. The zener voltage is specified at 38 V. This part includes automotive qualification (AEC-Q101) and is designated for automotive applications. Product status is active with ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the CRZ36(TE85L,Q,M) directly replace the DZ2W36000L in all applications?

A: The CRZ36(TE85L,Q,M) maintains the 36 V zener voltage and SOD-123F package compatibility. However, maximum power dissipation is 700 mW compared to 1 W in the original part. Applications requiring full 1 W dissipation must use KDZVTR36B or KDZVTFTR36B. The ±10% tolerance is wider than the original ±5%.

Q: What is the significance of the 38 V zener voltage in the Rohm parts?

A: The KDZVTR36B and KDZVTFTR36B are specified at 38 V nominal zener voltage, representing a 2 V deviation from the 36 V original specification. Circuit compatibility depends on whether this voltage shift is acceptable for the intended application. Applications with strict voltage regulation requirements may require evaluation of this parameter.

Q: Are all substitute parts available in the same package?

A: All substitute parts are available in the SOD-123F surface mount package, ensuring mechanical and electrical compatibility with the original PCB layout and assembly process.

Q: What is the difference between KDZVTR36B and KDZVTFTR36B?

A: Both parts are manufactured by Rohm Semiconductor with identical electrical specifications (38 V, 1 W, SOD-123F). The KDZVTFTR36B includes automotive qualification (AEC-Q101) and is designated for automotive applications. The KDZVTR36B is the standard industrial grade variant.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts are RoHS compliant. The original DZ2W36000L is RoHS Compliant. The Toshiba CRZ36(TE85L,Q,M) and both Rohm parts (KDZVTR36B and KDZVTFTR36B) are ROHS3 Compliant.

Q: What is the moisture sensitivity level for all parts?

A: All parts, including the original DZ2W36000L and all substitutes, have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Can the Rohm automotive-qualified part be used in non-automotive applications?

A: The KDZVTFTR36B automotive-qualified part can be used in non-automotive applications. Automotive qualification indicates additional testing and reliability standards but does not restrict use in other applications.
