Overview
The CMPZDA7V5 TR PBFREE is a dual-series Zener diode manufactured by Central Semiconductor Corp, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 7.5 V with a maximum power dissipation of 350 mW. The device operates within a junction temperature range of -65°C to +150°C and includes an integrated series resistor for current limiting. Key electrical parameters include a maximum reverse leakage current of 5 µA at 5.5 V and a typical dynamic impedance of 40 Ω at a test current of 5 mA.
Feature Summary
- Dual-series configuration integrates two Zener diodes in a single compact package.
- Built-in series resistor provides inherent current limiting functionality.
- Designed for surface-mount assembly using the standard SOT-23 footprint.
Applications
- Voltage reference circuits requiring stable dual-rail supplies.
- Transient voltage suppression in low-power signal lines.
- Clamping applications in portable electronic devices.
Procurement Notes
Verify the specific suffix 'TR PBFREE' against the manufacturer's official datasheet to confirm tape-and-reel packaging and lead-free compliance. Ensure the component matches the exact electrical specifications required for your circuit design before finalizing procurement orders.
Selection Notes
Select this component when space constraints necessitate a dual-diode solution in an SOT-23 package. Confirm that the 7.5 V breakdown voltage and 350 mW power rating align with the target application's thermal and voltage requirements.
Part Context
This part belongs to Central Semiconductor's CMPZDA series of dual-series Zener diodes. These components are designed to replace discrete dual-diode arrangements, offering a simplified layout and reduced board space consumption for voltage regulation and protection tasks.
Replacement Considerations
Consult official substitution guides for equivalent dual-series Zener diodes in SOT-23 packages. Verify pinout compatibility and electrical parameter tolerances before replacing the original component in existing designs.
