DZ23C13-7

Overview

The DZ23C13-7 is a dual Zener diode array manufactured by Diodes Incorporated, housed in an SOT-23 surface-mount package. It features a common cathode configuration with two silicon junctions within a single molded plastic case. The nominal Zener voltage is 13 V, with an operating range of 12.4 V to 14.1 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, and the device supports an operating temperature range from -65°C to +150°C. Electrical specifications include a maximum Zener impedance (ZZT) of 25 Ω and a typical temperature coefficient of +0.080 %/°C.

Feature Summary

• Dual Zener diodes integrated into a single common cathode configuration for space-efficient circuit design.
• High reliability qualification meeting JEDEC standards for robust performance in demanding environments.
• Environmentally compliant construction featuring lead-free plating, halogen-free materials, and antimony-free compounds.

Applications

• Voltage reference circuits requiring stable dual supply rails.
• Over-voltage protection stages for sensitive signal lines.
• Clamping applications in automated insertion manufacturing processes.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation before procurement. Commercial grade parts utilize the -7 suffix, while automotive-grade variants require the Q-suffix for AEC-Q101 qualification. Confirm that the requested part matches the exact electrical characteristics and packaging requirements defined in the latest datasheet revision DS18002 Rev. 22.

Selection Notes

Select this component when a compact dual Zener solution is required for voltage regulation or protection. Ensure the application operates within the specified 300 mW power dissipation limit and the -65°C to +150°C temperature range. Verify that the 13 V nominal breakdown voltage aligns with the target circuit thresholds and that the SOT-23 footprint fits the available board space constraints.

Part Context

This component belongs to the DZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series spans various voltage ratings from 2.7 V to 51 V, all sharing the same SOT-23 mechanical outline and 300 mW power rating. The DZ23C13-7 specifically addresses designs needing a 13 V reference point within a minimal three-terminal package.

Replacement Considerations

Direct functional equivalents within the same family include other DZ23C variants with different voltage ratings. For automotive applications requiring identical form, fit, and function with enhanced reliability standards, consider the corresponding Q-suffix part number from the manufacturer's automotive product listing.
