DZ23C10-7-F

Overview

The DZ23C10-7-F 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 10 V, operating within a range of 9.4 V to 10.6 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, supported by a thermal resistance of 417 °C/W from junction to ambient air. Electrical specifications include a maximum Zener impedance of 15 Ω at 1 kHz and a typical temperature coefficient of +0.065 %/°C.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation before procurement. Confirm that the commercial grade qualification meets the operational requirements of the target application environment. Ensure compatibility with standard surface-mount assembly processes and verify compliance with relevant environmental regulations such as RoHS and REACH standards.

Selection Notes

Select this component when a compact dual Zener solution is required for voltage regulation or protection tasks. Evaluate the thermal resistance and power dissipation limits relative to the expected ambient temperature conditions. Consider the ±5% voltage tolerance and the positive temperature coefficient characteristics to ensure stability across the specified operating temperature range of -65°C to +150°C.

Part Context

This device belongs to the DZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series offers various voltage options ranging from 2.7 V to 51 V, all sharing the same SOT-23 footprint and 300 mW power rating. The product line is designed to provide cost-effective and reliable solutions for general-purpose electronic applications requiring dual voltage references or clamping functions.

Replacement Considerations
