• Features low forward voltage drop of 1.2 V maximum at 200 mA forward current.
• Constructed as a highly reliable silicon device suitable for demanding environments.

Applications

• Industrial equipment voltage regulation
• Commercial electronic circuit protection
• Entertainment system power management
• Computer hardware voltage reference

Procurement Notes

Verify the specific ordering suffix requirements directly with Central Semiconductor Corp before placing orders. Confirm that the 'BK' and 'PBFREE' designations align with current manufacturing standards and environmental compliance mandates. Ensure compatibility with existing supply chain protocols and verify any applicable product lifecycle notices or discontinuation statuses prior to finalizing procurement actions.

Selection Notes

Select this component when a precise 39 V Zener reference is required in an axial leaded package. The 1.0 W power rating supports moderate current loads without excessive thermal management. Verify that the ±5% voltage tolerance meets the circuit's precision requirements. Ensure the DO-41 footprint matches the PCB layout constraints and that the operating temperature range covers the intended application environment.

Part Context
