AZ23C13 Equivalent & Substitute Parts

Part Overview

The AZ23C13 is an active-status zener diode array manufactured by Taiwan Semiconductor Corporation, configured as a 1 pair common anode device in SOT-23 surface mount packaging. This component is designed for small signal applications requiring voltage regulation and transient protection at 13 V nominal zener voltage. The part is ROHS3 compliant and REACH unaffected, making it suitable for current industrial and commercial applications. Substitute parts are identified based on identical electrical specifications and mechanical compatibility to ensure direct functional replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AZ23C13 are identified through parametric equivalence. The substitution criteria are based on the following key parameters that must remain identical:

• Zener voltage (Vz): 13 V nominal
• Voltage tolerance: ±5%
• Maximum power dissipation: 300 mW
• Maximum impedance (Zzt): 25 Ohms
• Reverse leakage current: 100 nA @ 10 V
• Operating temperature range: -55°C to 150°C
• Configuration: 1 Pair Common Anode
• Package type: SOT-23 (TO-236-3, SC-59, SOT-23-3)
• Mounting type: Surface Mount

Parts meeting all these specifications are classified as parametric equivalents and direct substitutes. Variations in manufacturer, packaging format (Tape & Reel vs. bulk), or internal device designation (such as RFG suffix) do not affect functional compatibility when all electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

Both the AZ23C13 and AZ23C13 RFG are active-status components manufactured by Taiwan Semiconductor Corporation with identical electrical and mechanical specifications. Selection between these parts is based on supply chain and inventory considerations rather than technical performance differences.

The AZ23C13 RFG variant carries an MSL (Moisture Sensitivity Level) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for industrial and commercial applications.

Component selection should prioritize availability and lead time requirements. The AZ23C13 RFG currently maintains higher inventory levels (6748 pieces) compared to the standard AZ23C13 (2200 pieces), making it suitable for high-volume production schedules. Both parts are supplied in Tape & Reel packaging format, appropriate for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can AZ23C13 RFG be used as a direct replacement for AZ23C13?

A: Yes. The AZ23C13 RFG is a parametric equivalent with identical zener voltage (13 V), tolerance (±5%), power rating (300 mW), impedance (25 Ohms), leakage current (100 nA @ 10 V), operating temperature range (-55°C to 150°C), configuration (1 Pair Common Anode), and SOT-23 package specifications. No circuit modifications are required.

Q: What does the RFG suffix indicate?

A: The RFG suffix is an internal device designation from Taiwan Semiconductor Corporation. It does not affect electrical performance or mechanical compatibility. Both AZ23C13 and AZ23C13 RFG meet identical specifications for all functional parameters.

Q: Are there package compatibility differences between these parts?

A: No. Both parts use the SOT-23 package (also designated TO-236-3 or SC-59) with identical pinout and mechanical dimensions. Both are surface mount components suitable for automated PCB assembly.

Q: What is the significance of the MSL rating on AZ23C13 RFG?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. This simplifies storage, handling, and logistics without requiring specialized dry-pack storage or baking procedures prior to assembly.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both AZ23C13 and AZ23C13 RFG are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for industrial and commercial applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical electrical specifications, mechanical dimensions, and pinout configuration allow direct substitution without design changes or circuit board modifications.
