Overview
The BAV74 is a silicon switching diode array manufactured by Siemens, designed for high-speed switching applications. It features a common cathode configuration with one pair of diodes housed in a surface-mount TO-236-3 (SC-59, SOT-23-3) package. The device supports a maximum DC reverse voltage of 50 V and an average rectified forward current of 200 mA per diode. Typical forward voltage drop is 1.25 V at specified conditions.
Feature Summary
- High-speed switching capability utilizing standard silicon technology
- Common cathode dual diode configuration for efficient circuit integration
- Surface-mount packaging suitable for automated assembly processes
Applications
- General purpose high-speed switching circuits
- Signal demodulation applications
- Logic level shifting interfaces
Procurement Notes
Verify component status as some sources indicate obsolete status while others list active availability. Confirm package type matches TO-236-3 requirements. Ensure supplier documentation aligns with Siemens Semiconductor Group specifications for electrical characteristics and thermal limits before finalizing orders.
Selection Notes
Select this component when a compact, common-cathode dual diode solution is required for high-speed signal processing. The 50V reverse voltage rating suits low-voltage logic and signal paths. Consider the SOT-23-3 footprint for space-constrained PCB layouts requiring standard switching performance without specialized fast-recovery characteristics.
Part Context
This part belongs to the BAV series of silicon switching diode arrays produced by Siemens Semiconductor Group. These components are widely used in consumer electronics and industrial control systems where reliable, fast switching is necessary. The BAV74 specifically offers a balanced trade-off between speed and current handling in a small outline transistor package.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Verify compatibility with generic equivalents based on matching pinout, voltage ratings, and package dimensions if direct Siemens sourcing is unavailable.
