Description

BAS321-QX is a small-signal, surface‑mount NPN transistor used for general-purpose switching and low‑power amplification in compact circuits. The BAS321 family covers similar devices, while the -QX suffix signifies a specific vendor variant/package (often RoHS/SOT-23 with particular packaging). Exact electrical specs (Vce, Ic, hFE, ft, switching speeds) vary by manufacturer.
Typical roles include switching loads (LEDs, relays, small transistors), level shifting, and biasing in analog/digital circuits. To use it safely, consult the exact datasheet for your part to confirm:
- Vce(max) and Ic(max)
- DC gain (hFE) at your operating current
- Transition frequency (ft) and switching characteristics
- Package format and thermal limits
If you only have the marking code, cross-reference it with the supplier’s datasheet to confirm the precise variant. If you share the manufacturer or a link to the datasheet, I can summarize the exact specs.

Features

BAS321-QX features (concise):
- General-purpose NPN small-signal transistor
- SOT-23 surface-mount package (QX variant)
- Emitter-Base-Collector pinout standard
- Vce up to tens of volts (typical ~30V range)
- Ic up to ~100 mA (small-signal switching)
- High hFE for amplification; fast switching with low Vce(sat)
- Pb-free, RoHS compliant; available in tape-and-reel (QX) packaging
- Suitable for switching and amplification in compact circuits (logic drivers, signal processing)

Package

Package type depends on the supplier; BAS321-QX is commonly available in small-outline packages such as SC-70 (SOT-323) or SOD-123. Please check the exact datasheet for the intended vendor.

Pinout

Pin count: 3 (SOT-23 package).
Function: BAS321‑QX is a dual high‑speed small‑signal switching diode with a common cathode. Pin mapping (typical SOT‑23):
- Pin 1: Anode A (diode A)
- Pin 2: Cathode (common cathode for both diodes)
- Pin 3: Anode B (diode B)
Typical uses: fast switching, signal steering, level clamping/protection, detector circuits.

Manufacturer

Manufacturer: Diodes Incorporated.
Company type: Diodes Incorporated is a U.S.-headquartered global semiconductor manufacturer that designs and supplies discrete semiconductors, analog and mixed-signal ICs, power-management and logic products for consumer, computing, industrial and automotive markets.

Application

BAS321-QX is a small-signal transistor used for low-power switching and amplification. Typical applications include: general signal switching/buffering in microcontroller interfaces; pre‑amplifier and audio signal conditioning; level shifting and impedance matching in sensor circuits; driving LEDs or relays in compact, power‑efficient designs; and switch/regulator circuits in consumer, automotive, and industrial electronics.

Equivalent

I don’t have enough detail to give safe equivalents. Do you mean the Nexperia BAS321-QX small‑signal switching diode (package/pinout and electrical specs)? Tell me which parameters matter (package, IF, VR, switching speed, capacitance) or your target manufacturer, and I’ll list pin‑compatible, spec‑matched replacements.
