Overview
The Central Semiconductor Corp 1N4454 BK PBFREE is a standard switching diode housed in a DO-35 through-hole package. It features a maximum repetitive reverse voltage of 75 V and an average rectified forward current of 150 mA. The device supports a surge forward current of 4 A and dissipates up to 500 mW of power. Operating junction temperatures range from -65°C to +200°C, with a storage temperature range extending to 300°C.
Feature Summary
- High conductance ultra-fast switching capability
- Extended thermal stability for high-temperature environments
- Robust surge current handling capacity
Applications
- General purpose switching circuits
- High-speed rectification applications
- Protection against voltage spikes
Procurement Notes
Verify the specific ordering suffix (BK PBFREE) ensures lead-free compliance and bulk packaging format. Confirm active status directly with Central Semiconductor or authorized distributors, as availability may vary by region. Request updated datasheets to validate electrical characteristics against current design requirements before finalizing procurement.
Selection Notes
Select this component when a fast-switching diode with moderate current ratings is required in a compact axial leaded package. Ensure the 75 V reverse voltage rating exceeds the peak inverse voltage in the circuit. Verify that the 150 mA continuous current and 4 A surge capabilities meet the load demands without exceeding the 500 mW power dissipation limit at the expected ambient temperature.
Part Context
This part belongs to the 1N4454 series of high-conductance ultra-fast diodes originally characterized by Fairchild Semiconductor and now produced by Central Semiconductor. The DO-35 package provides a standardized footprint for through-hole mounting on printed circuit boards, suitable for space-constrained designs requiring reliable switching performance.
Replacement Considerations
The 1N4454 TR PBFREE variant offers identical electrical specifications but utilizes tape-and-reel packaging for automated assembly. Cross-reference with other 1N4454 equivalents from different manufacturers only if pinout and package dimensions match exactly.
