CLL4716 BK Zener Diode Equivalent & Substitute Parts

Part Overview

The CLL4716 BK is a 39 V, 500 mW Zener diode manufactured by Central Semiconductor Corp in the SOD-80 (DO-213AC, MINI-MELF) surface mount package. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The part operates across a temperature range of -65°C to 200°C and maintains ±5% voltage tolerance at the specified Zener voltage.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLL4716 BK is determined by electrical parameter equivalence and package compatibility. The primary substitute identified is the CMHZ4716 BK, which maintains identical electrical specifications across all critical parameters: 39 V nominal Zener voltage, 500 mW maximum power dissipation, ±5% tolerance, 10 nA reverse leakage current at 29.6 V, and 1.5 V maximum forward voltage at 100 mA. Both parts are surface mount devices manufactured by Central Semiconductor Corp.

The key substitution criteria are:

• Zener voltage: 39 V (nominal)
• Power rating: 500 mW (maximum)
• Voltage tolerance: ±5%
• Reverse leakage current: 10 nA @ 29.6 V
• Forward voltage: 1.5 V @ 100 mA
• Mounting technology: Surface mount

The primary distinction between the main part and its substitute is the package format and product status. The CLL4716 BK uses SOD-80 packaging and is obsolete, while the CMHZ4716 BK uses SOD-123 packaging and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The CMHZ4716 BK is the primary substitute for the obsolete CLL4716 BK. Both components share identical electrical characteristics across all specified parameters, including Zener voltage, power dissipation, tolerance, leakage current, and forward voltage specifications.

The substitute part differs in two aspects:

Package Format: The CMHZ4716 BK uses SOD-123 packaging instead of the SOD-80 format of the main part. PCB layout modifications are required to accommodate the different package footprint.

Operating Temperature Range: The CMHZ4716 BK operates from -65°C to 150°C, compared to the main part's -65°C to 200°C range. For applications requiring operation above 150°C junction temperature, the substitute is not suitable.

The CMHZ4716 BK maintains active product status with 650 pieces in stock, ensuring availability for production and design implementation. The part carries identical ECCN (EAR99) and HTSUS (8541.10.0050) classifications as the main part.

Frequently Asked Questions (FAQ)

Q: Can the CMHZ4716 BK directly replace the CLL4716 BK without circuit modifications?

A: Electrical substitution is complete. However, the package change from SOD-80 to SOD-123 requires PCB footprint modification. Verify that the maximum operating temperature of 150°C (CMHZ4716 BK) meets application requirements, as the original part operates to 200°C.

Q: What is the difference between SOD-80 and SOD-123 packages?

A: SOD-80 (DO-213AC, MINI-MELF) and SOD-123 are distinct surface mount package formats with different physical dimensions and PCB land patterns. Component placement and routing must be adjusted accordingly.

Q: Are there other equivalent Zener diodes listed for the CMHZ4716 BK?

A: The CMHZ4716 BK documentation references cross-references to BZT52C39S-7-F, MMSZ5259B-7-F, BZT52C39-7-F, and DDZ9716-7. These parts share the same electrical specifications but may differ in package format and manufacturer.

Q: Is the CLL4716 BK still available for purchase?

A: The CLL4716 BK is classified as obsolete. However, 804 pieces are currently in stock. For new designs and long-term production, the active CMHZ4716 BK substitute is recommended.

Q: What compliance certifications apply to the CMHZ4716 BK?

A: The CMHZ4716 BK carries REACH Unaffected status, ECCN EAR99, and HTSUS 8541.10.0050 classification, matching the regulatory profile of the main part.
