Features

BAS21H features (typical, varies by manufacturer; check datasheet for exact numbers):
- NPN silicon small-signal transistor
- Fast switching speed for/general-purpose switching
- Package: SOT-23 (surface-mount)
- Collector current Ic: up to ~50 mA
- Collector-emitter voltage Vceo: around 65 V
- Transition frequency fT: roughly 200–300 MHz
- Gain (hFE): ~100–300 (at standard test conditions)
- Low noise, suitable for high-speed amplification
- Pb-free / compliant, tape-and-reel packaging options
Note: Exact ratings depend on the manufacturer and device lot. Always confirm with the specific BAS21H datasheet.

Package

BAS21H is a surface-mount diode in an SOT-23 (3-pin) package, used as a general-purpose high-speed switching diode.

Pinout

- Pin count: 2 pins (anode and cathode).
- Function: BAS21H is a small-signal fast-switching diode used for high-speed switching and general signal-diode applications.

Manufacturer

BAS21H is a general-purpose switching diode produced by several manufacturers; a common source is Nexperia.
Nexperia is a Dutch multinational semiconductor company that specializes in discrete and logic devices (diodes, transistors, MOSFETs) used in automotive, industrial, and consumer electronics.

Application

BAS21H is a general-purpose high-frequency NPN transistor (SMD). Typical application areas:
- RF and other small-signal amplification and switching
- Buffer/driver stages, oscillators, and mixer front-ends
- Detectors/demodulators and RF front-end circuits
- Use in radios, mobile devices, receivers, instrumentation, and other SMD circuits
Note: Check the datasheet for exact Vce, Ic, and ft specs for your design.
