Overview
Description
BAS28 is a dual silicon fast-switching diode used in high-speed signal paths, clipping/limiting, and detector circuits. It typically contains two diodes in one SMD package (configuration—common cathode vs. common anode—depends on vendor). Key points:
- Fast switching, low capacitance suitable for RF/signal applications.
- Forward voltage roughly 0.6–0.8 V at a few mA.
- Reverse voltage generally tens of volts (vendor specifics vary; common ranges 50–100 V).
- Forward current per diode on the order of 100–200 mA (check datasheet).
- Leakage and recovery parameters are specified per part variant.
The suffix “215” (as in BAS28,215) is usually a batch/date code or packaging variant, not a standard electrical spec. For exact pinout, configuration, VR, IF, IR, and Cj, consult the specific manufacturer’s BAS28 datasheet. If you have a particular supplier part number (e.g., BAS28–XX in SOT-23), use that to get the precise specs.

Equivalent
Do you mean the BAS28-215 part (or BAS28 / 215 as two separate parts)? Please confirm the exact full part number and package (SOT‑23, SOD‑523, etc.) or the device type (switching diode, transistor) so I can list accurate equivalents.
Pinout
- Pin count: 3 pins (SOT-23 package)
- Function: Dual silicon switching diodes in one package with a common terminal (two diodes sharing a common anode or common cathode; exact pinout depends on the specific BAS28-215 variant). Used for fast switching, level shifting, and clipping applications.

Application
BAS28 and BAS215 are fast small-signal silicon switching diodes. Common applications include:
- Fast switching in logic, timing, and pulse circuits
- RF/IF detectors, envelope detectors, and demodulation
- Clipping/limiting and protection in receivers/transceivers
- High-frequency rectification and peak detection
- Mixer/phase-detection networks and sample-and-hold circuits
Note: always check the datasheet for reverse voltage, current ratings, and package.
