DZ2J220M0L Zener Diode Equivalent & Substitute Parts

Part Overview

The DZ2J220M0L is a 22 V, 200 mW surface mount zener diode manufactured by Panasonic Electronic Components in the SMini2-F5-B package. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers. Substitute parts must maintain the 22 V nominal zener voltage and surface mount configuration while accommodating variations in power dissipation, impedance, and package form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2J220M0L is determined by the following critical parameters:

Primary Matching Criteria:

• Voltage - Zener (Nom): 22 V (exact match required)
• Mounting Type: Surface Mount (required)
• RoHS Compliance: All substitutes must maintain RoHS compliance status

Secondary Compatibility Parameters:

• Power - Max: Substitutes rated at 200 mW or higher are acceptable
• Impedance (Max): Variations permitted within circuit design tolerances
• Current - Reverse Leakage @ Vr: Variations permitted within circuit design tolerances
• Package / Case: SC-90, SOD-323F, SOD-323, or equivalent surface mount packages

Acceptable Variations:

• Power dissipation may exceed 200 mW (300 mW, 500 mW acceptable)
• Impedance may vary from 80 Ohms (30 Ohms to 100 Ohms acceptable)
• Reverse leakage current may vary from 50 nA (up to 200 nA acceptable)
• Tolerance specifications may differ (±2%, ±2.11% acceptable)

All substitute parts listed maintain the 22 V zener voltage specification and surface mount configuration required for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

Direct Package Equivalents (Preferred for PCB Compatibility):

UDZSTE-1722B, UDZVFHTE-1722B, and UDZVTE-1722B are manufactured by Rohm Semiconductor in the SC-90, SOD-323F package, matching the original DZ2J220M0L form factor. These parts maintain 200 mW power dissipation and are all ROHS3 compliant with unlimited moisture sensitivity rating. All three are currently in active production status with substantial inventory availability.

UDZVFHTE-1722B carries AEC-Q101 automotive qualification and is specified for automotive applications. This part is suitable for designs requiring automotive-grade components.

Higher Power Capability Alternative:

MM3Z22VST1G (onsemi) provides 300 mW power dissipation in the SOD-323 package with improved impedance characteristics (55 Ohms versus 80 Ohms). This part is ROHS3 compliant and active in production. The SOD-323 package is mechanically compatible with SOD-323F applications.

TFZGTR22B (Rohm Semiconductor) offers the highest power dissipation at 500 mW in the TUMD2 package with the lowest impedance (30 Ohms). This part is suitable for applications requiring enhanced thermal performance. ROHS3 compliant and active in production.

Compliance Status:

All substitute parts maintain RoHS compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can MM3Z22VST1G replace DZ2J220M0L directly on the PCB?

A: MM3Z22VST1G is functionally equivalent with matching 22 V zener voltage and surface mount configuration. The SOD-323 package is mechanically compatible with SOD-323F footprints. The 300 mW power rating exceeds the original 200 mW specification, providing additional thermal margin. Verify PCB footprint compatibility before assembly.

Q: What is the difference between UDZSTE-1722B, UDZVFHTE-1722B, and UDZVTE-1722B?

A: All three parts are manufactured by Rohm Semiconductor in the SC-90, SOD-323F package with identical 22 V, 200 mW specifications. UDZVFHTE-1722B includes AEC-Q101 automotive qualification and is specified for automotive applications. UDZSTE-1722B and UDZVTE-1722B are general-purpose industrial grade. Tolerance specifications vary slightly (±2%, ±2.11%, and unspecified respectively). Operating temperature ranges differ: UDZVFHTE-1722B is specified to 150°C maximum, while UDZSTE-1722B and UDZVTE-1722B operate from -55°C to 150°C.

Q: Is TFZGTR22B suitable as a substitute despite the different package?

A: TFZGTR22B maintains the 22 V zener voltage and surface mount configuration. The TUMD2 package differs from the original SMini2-F5-B package. This part is suitable only if the PCB footprint accommodates the TUMD2 form factor. The 500 mW power rating and 30 Ohms impedance provide superior performance characteristics compared to the original specification.

Q: Why do some substitute parts have higher power ratings?

A: Higher power-rated zener diodes (300 mW, 500 mW) are functionally equivalent substitutes for 200 mW applications. The increased power dissipation capability provides additional thermal margin and does not affect circuit operation. These parts are suitable for direct replacement in applications where the original 200 mW rating is adequate.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 compliant. The original DZ2J220M0L is RoHS compliant. All parts maintain unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing processes.

Q: What is the significance of the ±2.5% tolerance on the original part?

A: The ±2.5% tolerance specifies the accuracy of the 22 V zener voltage. Substitute parts with ±2%, ±2.11%, or unspecified tolerance are acceptable. Tighter tolerance specifications (±2%) provide improved voltage accuracy. For applications requiring specific tolerance performance, select parts with matching or tighter tolerance specifications.

Q: Can I use UDZVFHTE-1722B in non-automotive applications?

A: UDZVFHTE-1722B is qualified to AEC-Q101 automotive standards but is functionally suitable for general-purpose industrial applications. The automotive qualification indicates enhanced reliability testing and quality assurance. This part is acceptable for non-automotive use where the additional qualification provides design margin.
