Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact packaging and compliance status. Ensure the requested variant matches the required RoHS or REACH specifications. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when a 27 V reference point is required with 1 W power handling capability. The DO-41 package suits through-hole assembly processes. Consider the 5% voltage tolerance and 35 Ohm impedance characteristics for precision requirements. Verify thermal derating needs if operating near the maximum junction temperature limit.
Part Context
This device belongs to the 1N47xxA series of hermetically sealed glass Zener diodes licensed by onsemi. These components are characterized by double slug type construction and are widely used in industrial and commercial electronics where reliable voltage clamping is essential. The series covers a broad voltage range from 3.3 V to 100 V.
Replacement Considerations
Compatible substitutes include 1N4750A from other manufacturers such as Rectron or Taiwan Semiconductor. Verify pinout compatibility and ensure equivalent Zener voltage and power dissipation ratings. Check for matching package dimensions and thermal characteristics to guarantee seamless integration into existing designs.
