1N914B BK

Overview

The 1N914B BK is a silicon switching diode manufactured by Central Semiconductor Corp. It is housed in a DO-35 glass axial leaded package, designated with the 'BK' suffix indicating black band marking. The device is designed for high-speed switching applications and general-purpose rectification. Key electrical characteristics include a maximum repetitive peak reverse voltage of 100V and a maximum average forward rectified current of 150mA. It features a low forward voltage drop and fast recovery time, making it suitable for use in logic circuits, pulse generation, and signal processing tasks within electronic systems.

Feature Summary

• High-speed switching capability with fast recovery time
• Glass axial leaded construction for environmental stability
• Low forward voltage drop for efficient power handling
• Rated for 100V repetitive peak reverse voltage

Applications

• Logic level signal switching
• Pulse generation and shaping circuits
• General-purpose rectification in low-power electronics
• Clamping and protection circuits

Procurement Notes

Verify the specific datasheet version for the 1N914B BK to confirm exact electrical tolerances and mechanical dimensions. Ensure compatibility with existing PCB footprints for the DO-35 package. Confirm that the black band marking aligns with your assembly identification requirements. Check for any RoHS compliance status if required by your manufacturing standards. Validate supplier authorization to ensure component authenticity.

Selection Notes

Select this component when a standard silicon switching diode with 100V reverse voltage rating is required. The DO-35 package is suitable for through-hole mounting. Consider thermal derating if operating near maximum current limits. Compare forward voltage specifications against circuit requirements to ensure adequate signal integrity. Verify that the switching speed meets the frequency demands of the application.

Part Context

The 1N914 series is a widely recognized standard for small-signal silicon switching diodes. Central Semiconductor produces variants under this designation, often focusing on legacy support or specific marking requirements. The 'BK' suffix typically denotes the physical marking style rather than a change in electrical function. This part belongs to the broader category of discrete semiconductor diodes used in fundamental electronic circuit design.

Replacement Considerations

Standard equivalents include the 1N914, 1N914TR, and 1N4148. Verify pinout and package compatibility before substitution. Electrical parameters such as reverse leakage current and recovery time should be compared to ensure functional equivalence in the specific circuit context.
