AZ23C5V6

Overview

The AZ23C5V6 is a dual surface mount Zener diode manufactured by Taiwan Semiconductor Corporation, housed in an SOT-23 package. It features a nominal Zener voltage of 5.6 V with a tolerance of ±5%. The device operates within a Zener voltage range of 5.2 V to 6.0 V and has a maximum power dissipation of 300 mW at 25°C ambient temperature. Key electrical parameters include a Zener impedance (Zzt) of 5 Ω max at IzT = 1 mA, a leakage current (Ir) of 1 µA max at VR = 0.1 V, and a thermal resistance (RθJA) of 420 °C/W. The junction temperature range spans from -55°C to +150°C.

• Moisture sensitivity level 1 per J-STD-020 for automated assembly

Applications

• Low voltage stabilizers or voltage references
• Adapters
• Lighting applications
• On-board DC/DC converters

Procurement Notes

Verify the specific ordering suffix when purchasing, as variations such as 'RF' indicate standard packaging while 'G' denotes halogen-free green compound. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications before finalizing orders. Ensure compatibility with automated assembly processes given the component's design characteristics.

Selection Notes

Select this component for applications requiring precise dual Zener regulation in space-constrained environments. The SOT-23 package facilitates efficient PCB layout. Consider the 300 mW power dissipation limit and thermal resistance when designing heat management strategies. Verify that the 5.6 V nominal voltage aligns with the target reference or stabilization requirements.

Part Context

This part belongs to the AZ23C series, which covers a wide Zener voltage selection range from 2.7 V to 51 V. All devices in this series share identical mechanical data, including the SOT-23 case and UL 94V-0 molding compound. The series is designed for dual surface mount applications, offering consistent performance characteristics across various voltage ratings.

Replacement Considerations

Cross-reference with other manufacturers' dual Zener diodes in the SOT-23 package if supply constraints exist. Verify that substitute parts match the 300 mW power rating, 5.6 V nominal voltage, and ±5% tolerance. Ensure pinout compatibility and thermal performance metrics are equivalent to maintain circuit integrity.
