BZX584C16-V-G-08 Equivalent & Substitute Parts

Part Overview

The BZX584C16-V-G-08 is a Zener diode rated at 16 V nominal voltage with 200 mW maximum power dissipation in a surface mount SOD-523 package. Manufactured by Vishay General Semiconductor - Diodes Division, this component is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, equivalent substitute parts are necessary to maintain design continuity and ensure long-term supply chain reliability for applications requiring 16 V Zener regulation in compact surface mount form factors.

Substitute Part Grouping Explanation

Substitution of the BZX584C16-V-G-08 is determined by the following critical parameters:

Primary Substitution Criteria:

Zener voltage: 16 V nominal (fixed requirement)
Package type: SOD-523 or equivalent 0603/SOD-523F form factor
Mounting type: Surface mount
Compliance: RoHS3 and REACH requirements

Secondary Compatibility Factors:

Power rating: Minimum 200 mW (equal or greater acceptable)
Voltage tolerance: ±5% or tighter
Operating temperature range: Must encompass -65°C to 150°C or be suitable for intended application
Reverse leakage current: 50 nA or lower at specified voltage

Substitute parts are grouped into two categories: direct SOD-523 package equivalents and alternative package form factors (0603/SOD-523F) that maintain electrical compatibility while offering different mechanical configurations.

Engineering Selection Recommendations

Primary Recommendation: BZX584C16-G3-08

The BZX584C16-G3-08 from Vishay is the direct active equivalent. It maintains identical electrical specifications (16 V, ±5% tolerance, 200 mW power rating, SOD-523 package) and is manufactured by the same supplier as the original part. This part is currently in active production status with substantial inventory availability (6,172 units). It carries ROHS3 compliance and REACH unaffected status, matching the original part's regulatory certifications. The lower impedance (10 Ω vs. 40 Ω) provides improved performance characteristics.

Secondary Recommendation: DDZ9703T-7

The DDZ9703T-7 from Diodes Incorporated is suitable for applications where 150 mW power rating is acceptable. It maintains the 16 V nominal voltage, ±5% tolerance, and full -65°C to 150°C operating temperature range. This part offers the lowest reverse leakage current (50 nA @ 12.1 V) and is available in high volume (177,200 units). ROHS3 and REACH compliance are confirmed.

Alternative for Reduced Power Requirements: BZT52C16T-TP

The BZT52C16T-TP from Micro Commercial Co is applicable for designs requiring only 100 mW power dissipation. It maintains 16 V nominal voltage, ±5% tolerance, and full temperature range operation. This part is suitable for lower-power applications and offers high availability (6,622 units).

Package Alternative: CZRU52C16 or CZRUR52C16

The Comchip Technology parts CZRU52C16 and CZRUR52C16 provide 0603/SOD-523F package alternatives while maintaining 16 V nominal voltage and ±5% tolerance. These are applicable when PCB layout constraints require the 0603 form factor. Operating temperature range is -55°C to 125°C, which may limit use in applications requiring the full -65°C lower temperature specification.

Frequently Asked Questions (FAQ)

Q: Can BZX584C16-G3-08 directly replace BZX584C16-V-G-08 without circuit modification?

A: Yes. Both parts share identical nominal voltage (16 V), tolerance (±5%), power rating (200 mW), and SOD-523 package. The BZX584C16-G3-08 features lower impedance (10 Ω vs. 40 Ω), which provides superior performance. No circuit changes are required.

Q: Is BZT52C16T-7 a suitable substitute despite its ±6% tolerance versus ±5%?

A: BZT52C16T-7 is electrically compatible for most applications. The ±6% tolerance is marginally wider than the original ±5%. The part offers higher power rating (300 mW vs. 200 mW), which provides design margin. Tolerance impact must be evaluated against specific circuit requirements.

Q: Why do CZRU52C16 and CZRUR52C16 have a reduced operating temperature range?

A: These Comchip parts are specified for -55°C to 125°C operation, compared to the original -65°C to 150°C range. Applications requiring full temperature range coverage should use SOD-523 package alternatives. The 0603/SOD-523F package form factor may impose thermal limitations.

Q: What is the difference between CZRU52C16 and CZRUR52C16?

A: Both parts are electrically identical 16 V Zener diodes in 0603/SOD-523F package with 150 mW power rating and ±5% tolerance. CZRUR52C16 is the Tape & Reel variant. Selection depends on packaging and supply chain requirements.

Q: Can BZX584B16-TP be used in place of BZX584C16-V-G-08?

A: BZX584B16-TP is compatible for most applications. It maintains 16 V nominal voltage and SOD-523 package. However, it features tighter tolerance (±2% vs. ±5%), lower power rating (150 mW vs. 200 mW), and reduced lower temperature limit (-55°C vs. -65°C). Use is appropriate when these specifications align with application requirements.

Q: Is DDZ9703T-7 suitable for high-temperature applications?

A: Yes. DDZ9703T-7 maintains the full -65°C to 150°C operating temperature range of the original part. It is suitable for applications requiring extended temperature operation. The 150 mW power rating is the primary limitation compared to the original 200 mW specification.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts listed carry ROHS3 compliance and REACH unaffected status, matching the original BZX584C16-V-G-08 certifications. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no special moisture handling requirements.
