Overview
The DZ23C20_R1_00001 is a dual surface mount Zener diode from the Panjit DZ23C2V4 series, housed in an SOT-23 package. It features a common cathode configuration with two independent Zener elements sharing a single cathode terminal. The nominal Zener voltage is 20 V, with a tolerance range of 19.00 V to 21.00 V. Maximum power dissipation is rated at 300 mW, and the maximum reverse leakage current is specified as 100 nA at 15.0 V. The device exhibits a maximum Zener impedance of 50 Ohms at a test current of 5.0 mA. Operating junction and storage temperatures span from -65°C to +150°C.
Feature Summary
- Dual Zener diodes integrated into a single compact SOT-23 package for space-efficient circuit design.
- Common cathode configuration allows shared grounding and simplified routing in low-voltage regulation applications.
- Manufactured using lead-free materials compliant with EU RoHS 2.0 directives and green molding compounds per IEC 61249 standards.
Applications
- Voltage reference circuits requiring stable dual supply rails.
- Clamping and protection stages in consumer electronics.
- General-purpose signal conditioning within automated assembly processes.
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging orientation and reel size. The R1 designation indicates tape and reel packing on a 7-inch plastic reel. Confirm compliance requirements such as RoHS status and material specifications directly with the manufacturer before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener array with a common cathode topology is required in a small outline transistor package. Ensure the 300 mW power dissipation rating aligns with the thermal management capabilities of the target PCB layout. Verify that the 20 V nominal breakdown voltage meets the specific clamping or reference requirements of the application circuit.
Part Context
This part belongs to the DZ23C2V4 series, which encompasses dual Zener diodes with nominal voltages ranging from 2.4 V to 51 V. All members of this series share identical mechanical dimensions, pin configurations, and maximum ratings, differing only in their specific Zener voltage characteristics and marking codes.
Replacement Considerations
Direct replacements must match the SOT-23-3 footprint, common cathode configuration, and 300 mW power rating. Verify that substitute components offer equivalent Zener impedance and leakage current specifications at 20 V to ensure circuit performance parity.
FAQ
What is the electrical configuration of the DZ23C20?
The DZ23C20 utilizes a dual common cathode configuration, meaning both Zener diodes share a single cathode terminal while maintaining separate anodes.
How is the R1 suffix defined in the ordering code?
According to the datasheet, the R1 packing code signifies Tape and Reel (T/R) packaging on a 7-inch plastic reel.
What is the maximum operating temperature for this device?
The maximum operating junction temperature and storage temperature range extends up to +150°C.
