AZ23C39 Equivalent & Substitute Parts

Part Overview

The AZ23C39 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 applications requiring voltage regulation and transient protection at 39 V nominal zener voltage with 300 mW maximum power dissipation. 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, mechanical compatibility, and regulatory compliance to ensure direct functional replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AZ23C39 are identified through parametric equivalence. The substitution logic is based on the following critical parameters that must remain identical:

• Zener Voltage (Vz): 39 V nominal
• Voltage Tolerance: ±5%
• Maximum Power Dissipation: 300 mW
• Maximum Impedance (Zzt): 90 Ohms
• Reverse Leakage Current: 100 nA @ 29 V
• Operating Temperature Range: -55°C ~ 150°C
• Configuration: 1 Pair Common Anode
• Package Type: SOT-23 (TO-236-3, SC-59, SOT-23-3)
• Mounting Type: Surface Mount
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

Parts meeting all these specifications are classified as parametric equivalents and direct functional substitutes. Variations in manufacturer, packaging format (Tape & Reel vs. alternative formats), or moisture sensitivity level do not affect electrical or mechanical compatibility when all core parameters align.

Parameter Comparison

Engineering Selection Recommendations
