Overview
The Panjit AZ23C3V9_R1_00001 is a dual surface mount Zener diode from the AZ23C2V4 series, housed in an SOT-23 package. It features a common anode configuration with a nominal Zener voltage of 3.9 V and a power dissipation rating of 300 mW. The device operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a maximum Zener impedance of 95 Ω at a test current of 5.0 mA and a maximum reverse leakage current of 10 μA at 1.0 V. The component complies with EU RoHS directives and utilizes halogen-free green molding compound.
Feature Summary
- Dual Zener diodes integrated in a single common anode configuration for space-efficient circuit design.
- Suitable for automated insertion processes due to standardized surface mount packaging.
- Constructed with lead-free terminals and halogen-free green molding compound.
Applications
- Voltage reference circuits requiring dual stable potential sources.
- Clamping applications for signal protection in low-power electronics.
- Biasing networks in transistor amplifier stages.
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packing quantity and reel specifications. Confirm compliance requirements such as RoHS status directly with the manufacturer or authorized distributors before procurement. Ensure storage conditions align with moisture sensitivity levels specified in the datasheet to maintain component integrity during assembly.
Selection Notes
Select this component when a dual Zener array with a common anode topology is required in a compact SOT-23 footprint. Evaluate the 300 mW power dissipation limit against thermal derating curves for high-temperature environments. Compare the 95 Ω impedance and 10 μA leakage current against circuit tolerance requirements to ensure adequate performance stability.
Part Context
This part belongs to the AZ23C2V4 series, which offers a wide range of Zener voltages from 2.4 V to 51 V in the same SOT-23 package. The series provides consistent mechanical dimensions across voltage variants, simplifying PCB layout for designs requiring multiple voltage references. Other series members share identical thermal and electrical structural parameters.
Replacement Considerations
Direct substitutes must match the SOT-23 package, common anode configuration, and 3.9 V nominal voltage. Verify that alternative components meet the 300 mW power dissipation and 95 Ω impedance specifications. Cross-reference marking codes if visual identification is required for assembly verification.
