Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLZ22C-GS08 is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Zener voltage rating of 22 V nominal
• Power dissipation capacity of 500 mW minimum
• Surface mount package classification (SOD-80 / DO-213AC / MINI-MELF)
• Operating temperature range compatibility

Compliance & Regulatory Criteria:

• RoHS3 compliance status
• REACH unaffected classification
• Moisture sensitivity level MSL 1 (Unlimited)

The substitute part CLL5251B TR PBFREE meets all electrical and mechanical requirements for direct substitution. Both components share identical nominal Zener voltage, power rating, and package designation, with compatible operating temperature ranges and regulatory compliance profiles.

Parameter Comparison

Engineering Selection Recommendations

Both the TLZ22C-GS08 and CLL5251B TR PBFREE are Active status components with full RoHS3 compliance and REACH unaffected classification. The substitute part CLL5251B TR PBFREE provides equivalent electrical performance with identical nominal Zener voltage and power rating in the same surface mount package.

The CLL5251B TR PBFREE offers an extended operating temperature range to 200°C compared to the TLZ22C-GS08 maximum of 175°C, providing additional thermal margin in high-temperature applications. The substitute part also demonstrates lower forward voltage drop (1.25 V versus 1.5 V at 200 mA) and marginally lower impedance (29 Ohms versus 30 Ohms), resulting in improved efficiency characteristics.

Both components maintain unlimited moisture sensitivity rating and are suitable for automated assembly processes without special handling requirements. Selection between these parts depends on application-specific thermal requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CLL5251B TR PBFREE be used as a direct replacement for TLZ22C-GS08?

A: Yes. Both components share identical nominal Zener voltage (22 V), power dissipation (500 mW), and surface mount package designation (SOD-80 / DO-213AC / MINI-MELF). Electrical and mechanical compatibility is confirmed across all critical parameters.

Q: What are the key differences between these two parts?

A: The CLL5251B TR PBFREE provides an extended operating temperature range (-65°C to 200°C versus -65°C to 175°C), lower forward voltage drop (1.25 V versus 1.5 V at 200 mA), and includes ±5% Zener voltage tolerance specification. Impedance is marginally lower at 29 Ohms versus 30 Ohms.

Q: Are both parts RoHS3 compliant?

A: Yes. Both TLZ22C-GS08 and CLL5251B TR PBFREE are RoHS3 compliant with REACH unaffected status and MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for high-temperature applications?

A: The CLL5251B TR PBFREE supports operation to 200°C, providing 25°C additional thermal margin compared to the TLZ22C-GS08 maximum of 175°C.

Q: Are there packaging or tape & reel considerations?

A: Both components are supplied in Tape & Reel (TR) packaging suitable for automated pick-and-place assembly. Package designation is identical: SOD-80 MiniMELF with DO-213AC case style.

Q: What is the reverse leakage current specification difference?

A: The TLZ22C-GS08 specifies 40 nA at 20 V reverse voltage, while the CLL5251B TR PBFREE specifies 100 nA at 17 V. These measurements are taken at different reference voltages and represent acceptable leakage characteristics for both components in their respective operating ranges.
