AZ23C13-7 Equivalent & Substitute Parts

Part Overview

The AZ23C13-7 is a Zener Diode Array manufactured by Diodes Incorporated, configured as 1 Pair Common Anode with a nominal Zener voltage of 13 V and maximum power dissipation of 300 mW. The device is packaged in SOT-23-3 (TO-236-3, SC-59) surface mount configuration.

This part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components that maintain functional compatibility within the specified electrical and mechanical parameters. Equivalent parts are available from the same manufacturer with improved product status and compliance certifications, while manufacturer-recommended alternatives from other suppliers offer comparable performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AZ23C13-7 is determined by the following critical parameters:

Electrical Parameters:

• Zener voltage nominal value: 13 V
• Voltage tolerance: ±5%
• Configuration: 1 Pair Common Anode
• Operating temperature range: -65°C to 150°C

Mechanical Parameters:

• Mounting type: Surface Mount
• Package compatibility: SOT-23-3 or equivalent footprint

Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS and REACH compliance status

Substitute parts are grouped into two categories:

1. Parametric Equivalent (Same Manufacturer): AZ23C13-7-F maintains identical electrical specifications and package footprint with improved product status and RoHS3 compliance.

2. Manufacturer-Recommended Alternative (Different Manufacturer): BZB784-C13,115 from NXP Semiconductors provides equivalent Zener voltage and configuration but operates at reduced maximum power (180 mW versus 300 mW) and uses a different package footprint (SOT-323 versus SOT-23-3).

Parameter Comparison

Engineering Selection Recommendations

AZ23C13-7-F (Diodes Incorporated) is the direct parametric equivalent and primary substitute. This part maintains identical electrical specifications (13 V nominal Zener voltage, 300 mW maximum power, ±5% tolerance, 25 Ohms maximum impedance) and identical package footprint (SOT-23-3). The part is currently in active product status with 17,580 units in stock. AZ23C13-7-F is ROHS3 compliant, addressing regulatory compliance requirements that the original AZ23C13-7 does not meet. This substitute requires no circuit redesign or PCB layout modification.

BZB784-C13,115 (NXP Semiconductors) is the manufacturer-recommended alternative from a different supplier. This part maintains the critical electrical parameters of 13 V nominal Zener voltage and ±5% tolerance with 1 Pair Common Anode configuration. However, the maximum power rating is reduced to 180 mW (compared to 300 mW), and the impedance specification increases to 30 Ohms (compared to 25 Ohms). The package footprint differs (SOT-323 versus SOT-23-3), requiring PCB layout modification. This substitute is suitable for applications where the reduced power dissipation rating is acceptable and where PCB redesign is feasible. The part is currently in active product status with 4,100 units in stock.

Selection between AZ23C13-7-F and BZB784-C13,115 depends on application power requirements and PCB layout constraints. For direct replacement without circuit modification, AZ23C13-7-F is the appropriate choice. For applications with lower power dissipation requirements and where PCB redesign is acceptable, BZB784-C13,115 provides an alternative from an established semiconductor manufacturer.

Frequently Asked Questions (FAQ)

Q: Can AZ23C13-7-F be used as a direct replacement for AZ23C13-7?

A: Yes. AZ23C13-7-F is a parametric equivalent with identical electrical specifications (13 V Zener voltage, 300 mW power rating, ±5% tolerance) and identical package footprint (SOT-23-3). No circuit modification or PCB layout change is required. The primary difference is improved product status (Active versus Discontinued) and ROHS3 compliance.

Q: What are the limitations of using BZB784-C13,115 as a substitute?

A: BZB784-C13,115 has two significant differences from the original AZ23C13-7. First, the maximum power dissipation is reduced from 300 mW to 180 mW, which may limit application in high-power circuits. Second, the package footprint differs (SOT-323 versus SOT-23-3), requiring PCB layout modification. The impedance specification also increases from 25 Ohms to 30 Ohms. This substitute is suitable only for applications where these parameter reductions are acceptable.

Q: Are all substitute parts RoHS compliant?

A: AZ23C13-7-F is ROHS3 compliant. RoHS compliance status for BZB784-C13,115 is not specified in the provided data. Verify RoHS compliance requirements with the specific application and regulatory environment before final component selection.

Q: What is the moisture sensitivity level for these parts?

A: All three parts (AZ23C13-7, AZ23C13-7-F, and BZB784-C13,115) have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can the package footprints be used interchangeably?

A: No. AZ23C13-7 and AZ23C13-7-F both use SOT-23-3 package footprint and are mechanically interchangeable. BZB784-C13,115 uses SOT-323 package footprint, which has different pin spacing and dimensions. PCB layout modification is required if substituting with BZB784-C13,115.

Q: What is the operating temperature range for BZB784-C13,115?

A: Operating temperature range for BZB784-C13,115 is not specified in the provided data. Confirm temperature specifications with the manufacturer before selecting this part for applications with specific temperature requirements.
