Description

PDTA144ET is a small-signal NPN transistor from Nexperia’s PDTA family, in a SOT-23 package. It’s intended for general-purpose switching and low-power amplification in surface-mount designs. Key points:
- Package/packaging: SOT-23; ET indicates tape-and-reel packaging; Pb-free.
- Use: general-purpose switching and amplification in low-power circuits.
- Electricals: device-dependent, but typically tens of volts Vce and hundreds of milliamps Ic, with gain (hFE) that varies with Ic and temperature; low Vce(sat) when saturated.
- Alternatives: SMT counterpart to classic through-hole transistors (e.g., 2N3904).
For exact ratings (Vce, Ic, hFE, power, temperature ranges) and layout recommendations, consult the latest PDTA144ET datasheet from Nexperia. If you need, I can pull specific figures from the datasheet.

Features

PDTA144ET is a NPN digital transistor with built-in base resistor. Key features:
- 3-pin SOT-23 package; no external base resistor required
- Built-in base resistor for direct logic drive (TTL/CMOS compatible input)
- Vceo around 50 V; Ic up to about 100 mA (varies by variant)
- Low input current and fast switching
- Low saturation voltage
- Pb-free/RoHS compliant; available in tape & reel
- ESD protection on input (typical) and robust operation in logic-driving applications
Note: exact electricals (Vceo, Ic, resistor values) can vary by specific PDTA144ET lot/variant—consult the datasheet for precise numbers.

Package

PDTA144ET uses a SOT-23-6 (SC-74A) package.

Pinout

PDTA144ET is a 3‑pin device in an SOT‑23 package: a pre‑biased (digital) NPN small‑signal transistor with built‑in base resistor(s) for direct logic drive. Function: switching/amplification (NPN). Pins (3 total): Base, Collector, Emitter (B, C, E) — SOT‑23 tape & reel suffix “T”.

Manufacturer

- Manufacturer: Nexperia.
- What kind of company: A global semiconductor company that designs and manufactures discrete components and protection devices (e.g., diodes, transistors, transistor arrays). It originated from NXP and now operates as an independent, worldwide supplier.

Application

PDTA144ET is a small-signal digital transistor with built-in bias resistors. Applications include:
- Direct-drive interfacing with MCUs/logic
- Switching LEDs, relays, or small loads
- Signal amplification/buffering in analog/digital circuits
- Driving high-side or low-side switches in automotive/industrial gear
- General-purpose switching in compact, low-power, surface-mount designs

Equivalent

PDTA144ET is a digital transistor (NPN) with built-in base resistors in SOT-23. Exact equivalents depend on the base resistor value and package. Common cross‑references come from other vendors’ DTA/DT A family parts with the same pinout and ratings. Please confirm the package (SOT‑23) and required ratings (Vce, Ic) or allow me to look up current cross references for precise substitutes.
