Overview
Description
Key characteristics:
- Maximum reverse voltage (V_R): 75V
- Average forward current (I_F): 200mA
- Small form factor: Often in SOD-323 or DO-35 packages
Applications include clipping, clamping, and protection circuits in communication devices, power supplies, and RF systems. Its fast recovery time minimizes signal distortion, ideal for digital and analog circuits.
For precise performance, always refer to the datasheet for operating conditions and thermal considerations.
Equivalent
- 1N4148: Common, general-purpose diode.
- BAV99: Dual series diode, similar specs.
- 1N914: Nearly identical to 1N4148.
- BAV70: Dual diode, SMD alternative.
- LL4148: Miniature glass version.
These substitutes match BAS31's key specs (fast switching, low capacitance). Verify voltage/current ratings for your application.
Pinout
Functions:
1. Anode (A): Positive terminal for forward current flow.
2. Cathode (K): Negative terminal; current flows out when forward-biased.
Key Features:
- Fast switching (low reverse recovery time).
- Used in rectification, clipping, and protection circuits.
- Low forward voltage (~1V).
Typical applications include signal demodulation, high-frequency circuits, and logic protection.
Application
1. Signal Demodulation – Extracting signals in RF and communication circuits.
2. High-Speed Switching – Fast switching in digital and logic circuits.
3. Protection Circuits – Clamping and transient voltage suppression.
4. Rectification – Low-voltage, high-frequency rectification.
5. Waveform Clipping – Shaping signals in audio and RF applications.
Its small signal handling, fast recovery, and low capacitance make it suitable for high-frequency and precision applications.
