概要
Description
PDTC114ET is an NPN digital transistor with a built‑in base resistor, designed to be driven directly from a microcontroller. The “ET” variant is a RoHS/compliant version; the “215” suffix is likely a package/lot or option code and is not a separate electrical spec. Key idea: it simplifies driving a load (LEDs, relays, small motors) by eliminating an external base resistor.
Typical use:
- Load connected between Vcc and the transistor’s collector; MCU output drives the base via the built‑in resistor.
- Provides a quick, compact switch with fewer components.
General (variant‑dependent) specs:
- Vce: ~30–35 V
- Ic: tens to around 100 mA
- Built‑in base bias improves tamper resistance to noise and simplifies design
Note: exact ratings and pinout depend on the specific PDTC114ET variant. For precise electrical specs and the meaning of “215,” consult the manufacturer’s datasheet.

Equivalent
Do you mean PDTC114ET? If so, it’s a pre‑biased NPN digital transistor in SOT‑23. Direct equivalents: DTC114E / PDTC114E (Toshiba, Diodes Inc., Vishay variants) and other DTC114-series parts with the same base‑resistor and hFE. Otherwise you can replace it with any NPN SOT‑23 digital transistor with matching Rbase and gain, or a discrete NPN plus an appropriate base resistor. Provide the datasheet/specs and I’ll give exact cross‑references.

Pinout
PDTC114ET (“,215” is a packaging/tape‑and‑reel suffix) is a single NPN "digital" transistor in a 3‑pin SOT‑23 package (3 pins total). Typical pin assignment (SOT‑23):
- Pin 1: Base (internal base resistor)
- Pin 2: Emitter
- Pin 3: Collector
Function: NPN switching transistor with an integrated base resistor for direct TTL/CMOS drive; used as a low‑side switch, level shifter or simple LED/relay driver.

Application
PDTC114ET and PDTC215ET are digital transistors with built-in base resistors, used for simple logic-level switching. Typical applications:
- Direct MCU/interface drive: no external base resistor, easy logic input
- Low-side switching of small loads: LEDs, indicators, relays, solenoids, small motors (within ratings), with flyback protection for inductive loads
- Signal buffering/level shifting: buffers/inverts between TTL/CMOS and other circuits
- Automotive/industrial control: compact, robust driver for sensors and actuators
- Prototyping/education: reduces component count in switch circuits
(Adapt to specific ratings of each model as needed.)
