DZ2S200M0L Equivalent & Substitute Parts

Part Overview

The Panasonic DZ2S200M0L is a 20 V, 150 mW Zener diode in surface mount SSMini2-F5-B packaging. This component is designed for voltage regulation and protection applications in electronic circuits. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers. Substitute parts must maintain the same nominal Zener voltage, power dissipation capability, and surface mount compatibility to ensure direct circuit replacement without redesign.

Substitute Part Grouping Explanation

Substitution of the DZ2S200M0L is determined by the following critical parameters:

Primary Matching Criteria:

Nominal Zener voltage of 20 V
Maximum power dissipation of 150 mW or greater
Surface mount packaging (SOD-523 / SC-79 compatible)
RoHS compliance status

Secondary Compatibility Factors:

Voltage tolerance within ±2.5% or tighter
Impedance (Zzt) at or below 80 Ohms
Reverse leakage current specifications
Moisture sensitivity level MSL 1 (Unlimited)

All identified substitute parts meet or exceed the primary matching criteria. Variations in secondary parameters reflect different manufacturer specifications and do not preclude functional equivalence in typical circuit applications.

Engineering Selection Recommendations

BZX585-B20,115 (Nexperia USA Inc.): This substitute provides 300 mW maximum power dissipation, exceeding the original 150 mW specification. The part carries AEC-Q100 automotive qualification and operates across -65°C to 150°C. The tighter ±2% tolerance and lower impedance (55 Ohms) offer improved voltage regulation characteristics. This option is suitable for applications requiring enhanced thermal margin or automotive-grade reliability.

EDZVT2R20B (Rohm Semiconductor): This substitute matches the original 150 mW power rating and provides ±2% tolerance with 85 Ohms impedance. The part is active with ROHS3 compliance and operates across -55°C to 150°C. The EDZV series designation indicates standard industrial-grade performance. This option provides direct functional equivalence with improved availability.

EDZVFHT2R20B (Rohm Semiconductor): This substitute matches the original 150 mW power rating with ±2.18% tolerance and 85 Ohms impedance. The part carries AEC-Q101 automotive qualification and operates to 150°C junction temperature. This option is suitable for automotive applications requiring qualified component status.

All three substitutes are currently in active production with confirmed inventory availability and meet RoHS compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the BZX585-B20,115 with 300 mW rating replace the 150 mW DZ2S200M0L?

A: Yes. The 300 mW rating indicates higher power dissipation capability. In circuits designed for 150 mW operation, the higher-rated device operates within its specifications and provides additional thermal margin. The 20 V nominal Zener voltage, surface mount packaging, and RoHS compliance are identical.

Q: What is the significance of the impedance difference between 80 Ohms (original) and 55 Ohms (BZX585-B20,115)?

A: Lower impedance provides better voltage regulation under load changes. The BZX585-B20,115 with 55 Ohms impedance delivers tighter voltage stability compared to the original 80 Ohms specification. This is a performance improvement for voltage regulation applications.

Q: Are the Rohm EDZVT2R20B and EDZVFHT2R20B interchangeable?

A: Both parts share identical electrical specifications (20 V, 150 mW, 85 Ohms impedance) and SOD-523 packaging. The primary difference is qualification status: EDZVFHT2R20B carries AEC-Q101 automotive qualification, while EDZVT2R20B is industrial-grade. Selection depends on application requirements.

Q: Does the reverse leakage current difference affect circuit performance?

A: The original part specifies 50 nA @ 15 V, while substitute parts specify 100 nA @ 15 V. This difference is negligible in typical voltage regulation and protection circuits. Both values represent extremely low leakage and do not impact functional performance in standard applications.

Q: Are all substitutes compatible with the original SSMini2-F5-B footprint?

A: All substitutes use SOD-523 / SC-79 packaging, which is physically compatible with the original SSMini2-F5-B footprint. Direct PCB placement without modification is possible.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current standard. All parts listed meet hazardous substance restrictions and are suitable for applications requiring RoHS compliance.
