DZ23C39-7 Equivalent & Substitute Parts

Part Overview

The DZ23C39-7 is a Zener Diode Array manufactured by Diodes Incorporated, configured as a 1 Pair Common Cathode design with a nominal Zener voltage of 39 V and maximum power dissipation of 300 mW. The device is packaged in SOT-23-3 (TO-236-3, SC-59) surface mount configuration.

The DZ23C39-7 is discontinued at DiGi Electronics. Identification of equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution of the DZ23C39-7 is determined by strict equivalence across the following electrical and mechanical parameters:

Zener voltage: 39 V nominal
Voltage tolerance: ±5%
Maximum power dissipation: 300 mW
Maximum impedance: 90 Ohms
Operating temperature range: -65°C to 150°C
Configuration: 1 Pair Common Cathode
Package: SOT-23-3 surface mount

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Packaging format (bulk versus tape & reel) does not affect electrical or mechanical compatibility and does not preclude substitution.

Engineering Selection Recommendations

The DZ23C39-7-F is a direct parametric equivalent to the DZ23C39-7. All electrical specifications, mechanical dimensions, and thermal characteristics are identical. The primary differences are product status and regulatory compliance:

The DZ23C39-7 is discontinued and carries RoHS non-compliant status. The DZ23C39-7-F is an active product with ROHS3 compliance, making it suitable for applications subject to RoHS regulations and ensuring long-term component availability.

The DZ23C39-7-F is supplied in Tape & Reel (TR) packaging format, whereas the DZ23C39-7 is supplied in bulk. This packaging difference does not affect electrical performance or mechanical compatibility and is determined by procurement and assembly requirements.

For new designs and production applications, the DZ23C39-7-F is the appropriate selection. For legacy systems requiring the original DZ23C39-7, the DZ23C39-7-F provides full functional and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DZ23C39-7-F be used as a direct replacement for the DZ23C39-7?

A: Yes. The DZ23C39-7-F is a parametric equivalent with identical electrical specifications (39 V Zener voltage, ±5% tolerance, 300 mW maximum power, 90 Ohms maximum impedance), identical configuration (1 Pair Common Cathode), and identical package (SOT-23-3). Direct substitution is supported without circuit modification.

Q: What is the difference between the DZ23C39-7 and DZ23C39-7-F?

A: The electrical and mechanical specifications are identical. The DZ23C39-7-F differs in product status (active versus discontinued), RoHS compliance (ROHS3 compliant versus non-compliant), and packaging format (Tape & Reel versus bulk). These differences do not affect functional compatibility.

Q: Does the Tape & Reel packaging of the DZ23C39-7-F affect compatibility?

A: No. Packaging format (Tape & Reel versus bulk) is a supply and handling specification only. It does not affect the electrical performance, mechanical dimensions, or thermal characteristics of the component. The device itself is identical.

Q: Is the DZ23C39-7-F suitable for RoHS-regulated applications?

A: Yes. The DZ23C39-7-F carries ROHS3 compliance certification, making it suitable for applications subject to RoHS directives. The original DZ23C39-7 is RoHS non-compliant.

Q: Are there any temperature or impedance differences between these parts?

A: No. Both parts operate across the identical temperature range (-65°C to 150°C) and maintain the same maximum impedance specification (90 Ohms). All thermal and frequency-dependent characteristics are equivalent.

Q: Can the DZ23C39-7-F be used in existing PCB designs without layout changes?

A: Yes. The DZ23C39-7-F uses the identical SOT-23-3 package with the same pin configuration and mechanical footprint. No PCB layout modifications are required.
