GDZ3V0B-E3-08 Equivalent & Substitute Parts

Part Overview

The GDZ3V0B-E3-08 is a 3 V Zener diode rated at 200 mW, manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component in SOD-323 package is designed for voltage regulation and protection applications requiring precise 3 V reference voltage. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, inventory constraints, or design optimization within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GDZ3V0B-E3-08 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Zener voltage nominal value: 3 V
• Package type: SOD-323 (SC-76)
• Mounting type: Surface Mount
• RoHS3 compliance status
• Operating temperature range compatibility: -55°C to 150°C minimum

Allowable Parameter Variance:

• Power rating: Substitute parts may exceed 200 mW (250 mW or 320 mW acceptable for higher power applications)
• Tolerance: Substitute parts may have tighter tolerance (±2%) or equivalent tolerance (±5%)
• Impedance: Substitute parts may vary within specified maximum values
• Reverse leakage current: Substitute parts may have lower leakage specifications

All identified substitute parts maintain the 3 V nominal zener voltage, SOD-323 package configuration, surface mount capability, and RoHS3 compliance required for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active production components with full RoHS3 compliance and unlimited moisture sensitivity rating, matching the regulatory and environmental requirements of the GDZ3V0B-E3-08.

CMDZ5225B TR PBFREE (Central Semiconductor Corp): Provides 250 mW power rating with ±5% tolerance. Impedance specification of 29 Ohms is significantly lower than the main part. Operating temperature range extends to -65°C, providing broader low-temperature capability. Suitable for applications requiring moderate power increase with equivalent leakage characteristics.

PZU3.0B2A,115 (Nexperia USA Inc.): Offers 320 mW power rating with tighter ±2% tolerance specification. Impedance of 95 Ohms remains within acceptable range. Reverse leakage current reduced to 10 µA provides improved performance in low-leakage applications. Operating temperature range matches the main part specification.

PZU3.0BA,115 (Nexperia USA Inc.): Provides 320 mW power rating with ±5% tolerance. Impedance and leakage specifications identical to PZU3.0B2A,115. Operating temperature range matches the main part specification. Represents highest power capacity among substitutes.

Selection between substitutes depends on application requirements for power dissipation, tolerance precision, and leakage current performance within the 3 V zener voltage class.

Frequently Asked Questions (FAQ)

Q: Can CMDZ5225B TR PBFREE replace GDZ3V0B-E3-08 in all applications?

A: CMDZ5225B TR PBFREE maintains the 3 V nominal zener voltage and SOD-323 package required for mechanical and electrical compatibility. The 250 mW power rating exceeds the 200 mW specification of the main part, and impedance of 29 Ohms is lower than the 120 Ohm maximum. Substitution is valid where these parameter differences do not conflict with circuit design requirements.

Q: What is the difference between PZU3.0B2A,115 and PZU3.0BA,115?

A: Both parts are manufactured by Nexperia USA Inc. and share identical 3 V zener voltage, 320 mW power rating, SOD-323 package, and operating temperature range. The primary difference is tolerance specification: PZU3.0B2A,115 provides ±2% tolerance while PZU3.0BA,115 provides ±5% tolerance. Impedance and reverse leakage specifications are identical between the two parts.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging with SOD-323 package configuration, matching the surface mount requirements of the GDZ3V0B-E3-08.

Q: Do substitute parts meet the same compliance requirements?

A: All substitute parts are RoHS3 compliant with MSL rating of 1 (Unlimited), matching the regulatory and environmental compliance status of the main part. REACH status is unaffected for all parts.

Q: Which substitute part has the lowest reverse leakage current?

A: Both PZU3.0B2A,115 and PZU3.0BA,115 specify 10 µA reverse leakage current at 1 V, compared to 50 µA for the main part and CMDZ5225B TR PBFREE. Lower leakage current provides improved performance in precision voltage reference applications.

Q: Can I use a substitute part with higher power rating in a circuit designed for 200 mW?

A: Substitute parts with 250 mW or 320 mW ratings are electrically compatible with circuits designed for 200 mW operation. The higher power rating indicates greater thermal capability and does not create incompatibility. Circuit performance is determined by the maintained 3 V nominal zener voltage and compatible impedance characteristics.
