Substitute Part Grouping Explanation

Substitution of the GDZ2V2B-E3-08 is determined by the following critical parameters:

Primary Substitution Criteria:

Voltage - Zener (Nom): 2.2 V
Package / Case: SOD-323
Mounting Type: Surface Mount
Operating Temperature Range: Minimum -55°C, Maximum 150°C

Secondary Compatibility Factors:

Power - Max: Equal or greater than 200 mW

Engineering Selection Recommendations

GDZ2V2B-E3-18 (Parametric Equivalent)

The GDZ2V2B-E3-18 is a direct parametric equivalent to the GDZ2V2B-E3-08. Both components share identical electrical specifications including 2.2 V nominal zener voltage, ±4% tolerance, 200 mW maximum power, 100 Ohms maximum impedance, and 120 µA reverse leakage current. Both are manufactured by Vishay General Semiconductor, packaged in SOD-323, and maintain ROHS3 compliance with MSL 1 rating. This substitute provides full functional interchangeability with no design modifications required.

CMDZ2L2 TR PBFREE (Manufacturer-Recommended Alternative)

The CMDZ2L2 TR PBFREE is a manufacturer-recommended alternative manufactured by Central Semiconductor Corp. This component maintains the 2.2 V nominal zener voltage and SOD-323 package compatibility. The CMDZ2L2 TR PBFREE provides enhanced specifications in power dissipation (250 mW versus 200 mW) and extended lower operating temperature (-65°C versus -55°C). Tolerance is ±5% compared to ±4%, and impedance is 1000 Ohms compared to 100 Ohms. Reverse leakage current is 25 µA @ 1 V. This component is ROHS3 compliant with MSL 1 rating. Selection of this alternative is appropriate when higher power dissipation capability or extended low-temperature operation is required.

Frequently Asked Questions (FAQ)

Q: Can GDZ2V2B-E3-18 be used as a direct replacement for GDZ2V2B-E3-08?

A: Yes. The GDZ2V2B-E3-18 is a parametric equivalent with identical electrical and mechanical specifications. No circuit modifications are required.

Q: What are the key differences between GDZ2V2B-E3-08 and CMDZ2L2 TR PBFREE?

A: Both components share the same 2.2 V nominal zener voltage and SOD-323 package. The CMDZ2L2 TR PBFREE offers higher maximum power dissipation (250 mW versus 200 mW), lower operating temperature limit (-65°C versus -55°C), and lower reverse leakage current (25 µA versus 120 µA). Tolerance is ±5% compared to ±4%, and impedance is 1000 Ohms compared to 100 Ohms.

Q: Are all three parts RoHS compliant?

A: Yes. GDZ2V2B-E3-08, GDZ2V2B-E3-18, and CMDZ2L2 TR PBFREE are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the significance of the SOD-323 package for substitution?

A: The SOD-323 package is a surface mount semiconductor package with fixed mechanical and electrical interface dimensions. All three parts use this package, ensuring physical and electrical compatibility on printed circuit boards without layout modifications.

Q: When should CMDZ2L2 TR PBFREE be selected over the Vishay alternatives?

A: The CMDZ2L2 TR PBFREE should be selected when circuit design requires higher power dissipation capability (250 mW), extended low-temperature operation (-65°C), or lower reverse leakage current (25 µA). The ±5% tolerance and 1000 Ohms impedance are acceptable for applications where these specifications do not conflict with design requirements.

Q: Are there any temperature range limitations when substituting these parts?

A: The GDZ2V2B-E3-08 and GDZ2V2B-E3-18 operate from -55°C to 150°C. The CMDZ2L2 TR PBFREE extends the lower limit to -65°C. Substitution is valid only when the application operating temperature falls within the specified range of the selected component.

Q: What does ±4% tolerance mean for the zener voltage?

A: The ±4% tolerance indicates that the 2.2 V nominal zener voltage will fall within the range of 2.112 V to 2.288 V at specified test conditions. The CMDZ2L2 TR PBFREE has ±5% tolerance, resulting in a range of 2.09 V to 2.31 V.
