Overview
The CMSZDA8V2 TR PBFREE is a dual, common anode silicon zener diode from the CMSZDA series by Central Semiconductor Corp. It provides two independent voltage regulation channels within a single SOT-323 surface-mount package. The nominal zener voltage for each diode is 8.2 V, with a test current of 5.0 mA. Maximum reverse leakage current is specified at 0.7 µA at 1.0 V reverse voltage. The device supports a maximum power dissipation of 275 mW per diode and operates within a junction temperature range of -65°C to +150°C.
Feature Summary
- Dual configuration with a shared common anode terminal for simplified circuit layout
- High-quality silicon construction designed for industrial and commercial applications
- Compact SOT-323 surface-mount footprint suitable for space-constrained designs
Applications
- Industrial control systems requiring dual voltage references
- Commercial equipment needing compact regulation solutions
- Entertainment electronics utilizing surface-mount assembly
- Computer peripheral circuits requiring stable voltage clamping
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The PBFREE designation indicates lead-free compliance. Confirm availability status directly with authorized distributors as supply conditions may vary. Ensure the selected package matches the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when a dual zener configuration with a common anode is required in a small form factor. Verify that the 8.2 V nominal voltage aligns with the circuit's reference needs. Check that the 275 mW power dissipation rating meets the thermal requirements of the application environment.
Part Context
This part belongs to the CMSZDA2V4 through CMSZDA47V series, which offers a wide range of dual zener voltages in the same SOT-323 package. The series maintains consistent mechanical dimensions across all voltage variants, allowing for design flexibility without changing the physical board layout.
Replacement Considerations
Check for other parts in the CMSZDA series if different voltage ratings are needed. Verify pinout compatibility with existing designs. Confirm that alternative manufacturers offer equivalent dual common anode configurations in SOT-323 packages.
