Substitution of the CLL4713 BK is determined by the following critical parameters:

Primary Substitution Criteria:

Voltage - Zener (Nom): 30 V
Power - Max: 500 mW
Mounting Type: Surface Mount
Package / Case: SOD-80 (DO-213AC, MINI-MELF)

Secondary Compatibility Factors:

Operating Temperature Range: Minimum -65°C to at least 150°C
Tolerance: ±5% or unspecified (no tighter tolerance required)
Reverse Leakage Current: 10 nA or higher acceptable
Forward Voltage: 1.5 V or lower at specified current

Substitute parts are grouped into two categories:

Category 1: Same Package (SOD-80) - Direct Mechanical Substitutes Parts maintaining SOD-80 package compatibility with matching electrical specifications. These include Vishay TLZ series (TLZ30A-GS08, TLZ30B-GS08, TLZ30B-GS18, TLZ30C-GS08, TLZ30C-GS18, TLZ30D-GS08, TLZ30D-GS18) and Vishay TZM5256B-GS08.

Category 2: Alternative Package (SOD-123) - Functional Equivalent Central Semiconductor CMHZ4713 BK provides electrical equivalence with different surface mount package (SOD-123), requiring PCB layout modification.

Engineering Selection Recommendations

For Direct Replacement (Same Package, Same Footprint):

The Vishay TLZ30 series (TLZ30A-GS08, TLZ30B-GS08, TLZ30C-GS08, TLZ30D-GS08) and TZM5256B-GS08 provide pin-compatible substitutes in SOD-80 package. All are active products with ROHS3 compliance and REACH unaffected status. The TLZ30D-GS08 offers the highest inventory availability (90,200 pcs) and maintains the required 30 V nominal voltage and 500 mW power rating. Operating temperature range of -65°C to 175°C covers the majority of applications, though applications requiring operation above 175°C are limited to the original CLL4713 BK specification of 200°C maximum.

For Package-Agnostic Substitution:

The CMHZ4713 BK from Central Semiconductor Corp provides electrical equivalence with active product status. This part requires PCB layout modification due to SOD-123 package format. Operating temperature maximum of 150°C restricts use in high-temperature applications.

Compliance Considerations:

All recommended Vishay substitutes carry ROHS3 compliance and REACH unaffected status, suitable for regulated applications. Moisture Sensitivity Level (MSL) of 1 (Unlimited) across all Vishay parts eliminates moisture-related handling constraints.

Frequently Asked Questions (FAQ)

Q: Can TLZ30 series parts directly replace CLL4713 BK without PCB modification?

A: Yes. The TLZ30A-GS08, TLZ30B-GS08, TLZ30C-GS08, and TLZ30D-GS08 are packaged in SOD-80 (DO-213AC, MINI-MELF) with identical pin configuration and footprint to CLL4713 BK. No PCB layout changes are required.

Q: What is the difference between TLZ30A, TLZ30B, TLZ30C, and TLZ30D variants?

A: These variants differ in reverse leakage current specifications at different voltage measurement points (ranging from 40 nA @ 22.8 V to 40 nA @ 27.6 V) and impedance characteristics. All maintain 30 V nominal voltage and 500 mW power rating. Selection depends on specific leakage current requirements for the application.

Q: Is TZM5256B-GS08 equivalent to CLL4713 BK?

A: TZM5256B-GS08 matches the 30 V, 500 mW electrical specifications and SOD-80 package. It carries ±5% tolerance matching CLL4713 BK. Differences include lower forward voltage (1.1 V @ 200 mA versus 1.5 V @ 100 mA) and higher reverse leakage (100 nA @ 23 V versus 10 nA @ 22.8 V). These differences are within acceptable substitution parameters for most applications.

Q: Why does CMHZ4713 BK have a lower maximum operating temperature than CLL4713 BK?

A: CMHZ4713 BK is packaged in SOD-123 format with maximum operating temperature of 150°C, compared to CLL4713 BK in SOD-80 with 200°C maximum. Package thermal characteristics differ between SOD-123 and SOD-80 formats. Applications requiring operation above 150°C must use SOD-80 packaged alternatives.

Q: Are all substitute parts RoHS compliant?

A: All Vishay substitute parts (TLZ and TZM series) carry ROHS3 compliance certification. CMHZ4713 BK compliance status is not specified in provided data. Verify CMHZ4713 BK RoHS status with supplier for regulated applications.

Q: What inventory considerations apply to these substitutes?

A: TLZ30D-GS08 offers highest availability (90,200 pcs). TZM5256B-GS08 provides 17,800 pcs. Other TLZ variants range from 850 to 10,200 pcs. CMHZ4713 BK has 731 pcs available. Inventory levels support production requirements across all substitute options.

Q: Can I use CMHZ4713 BK in place of CLL4713 BK on existing PCBs?

A: No. CMHZ4713 BK uses SOD-123 package while CLL4713 BK uses SOD-80 package. These packages have different footprints and pin spacing. PCB redesign is required for CMHZ4713 BK implementation.
