Overview
The CMPZDA5V6 TR TIN/LEAD is a dual Zener diode manufactured by Central Semiconductor Corp. It features a nominal Zener voltage of 5.6 V with a maximum reverse leakage current of 3 uA and a Zener impedance of 10 Ohms. The device operates in an SOT-323-3 surface-mount package with a power dissipation rating of 275 mW. Electrical testing is conducted at a test current of 5 mA, yielding a forward voltage of 900 mV at 10 mA. The component supports a wide operating temperature range from -65 °C to +150 °C.
Feature Summary
- Dual configuration integrating two Zener diodes within a single compact SOT-323-3 package for space-constrained designs.
- Low leakage current specification of 3 uA ensures minimal power loss and high isolation in reverse bias conditions.
- Wide thermal operating range extending from -65 °C to +150 °C allows reliable performance in extreme environmental conditions.
Applications
- Voltage reference circuits requiring stable dual potential levels.
- Clamping applications for protecting sensitive inputs against transient overvoltages.
- Signal conditioning stages utilizing low-leakage characteristics for precision analog processing.
Procurement Notes
Verify the specific ordering suffix to confirm lead-free status and packaging format. Confirm that the tin/lead designation aligns with project compliance requirements. Request the official datasheet to validate electrical parameters against design specifications before finalizing procurement decisions.
Selection Notes
Select this component when a dual Zener configuration is required in a small outline transistor package. Ensure the 275 mW power dissipation limit accommodates the expected thermal load. Verify that the 5.6 V nominal voltage matches the circuit's clamping or reference requirements.
Part Context
This part belongs to the CMPZDA series of dual Zener diodes produced by Central Semiconductor. The series utilizes silicon planar technology housed in epoxy-molded packages. These components are designed for general-purpose voltage regulation and protection tasks in consumer and industrial electronics.
Replacement Considerations
Consult manufacturer cross-reference lists for verified substitutes. Ensure any replacement maintains the SOT-323-3 footprint and meets the 5.6 V Zener voltage tolerance. Verify equivalent leakage and impedance specifications to maintain circuit performance integrity.
