PDTC114YT,215

PDTC114YT,215 is a PDTC114-series digital transistor (NPN) with an integrated base resistor. It is meant to be driven directly from a microcontroller or logic output, eliminating the need for an external base resistor and simplifying interfacing to small loads.
Key points:
- Built-in base resistor enables direct logic drive of the transistor.
- Used to switch modest loads (LEDs, relays, small signals).
- Typical electricals (exact values depend on the variant): Vce in the tens of volts, Ic in the tens of milliamps range; input current dictated by the internal base resistor.
- Packaging: available in small SMD/through-hole configurations; “YT” denotes a specific package/configuration, while “215” is likely a date/lot code.
- Always consult the exact PDTC114YT datasheet for precise pinout, Ic, Vce, hFE, and any optional features (e.g., base-emitter resistors) for your application.

PDTC114YT,215 is a digital NPN transistor with a built‑in base resistor. Common cross‑refs (same family, similar Rin and ratings) include:
- Toshiba: DTC114Y (and related DTC114YE/DTC114YT)
- On Semiconductor: PDTC114E / PDTC114ET
- Vishay: DTC114EU (DTC114 series)
Note: Rin, Vce, and package vary by variant; always verify exact Rin, Vce, and footprint before substituting. If unsure, pull the exact equivalent by cross‑reference from the distributor’s datasheets.

PDTC114YT,215 is an NPN digital transistor with built-in bias resistor. Key features:
- Built-in base resistor (no external base resistor needed) for direct microcontroller drive.
- TTL/CMOS-compatible input; low drive current required to switch.
- Moderate load capability: typically drives loads like LEDs, transistors, small relays (IC up to around 50 mA range).
- Rated for voltages in tens of volts (Vce typically ~30–35 V) with low Vce(sat) for efficient switching.
- Internal protection features (bias network helps limit base current and protect the device during switching).
- Wide operating temperature range (commonly -40 °C to +125 °C).
- Small package options (SOT-23/SO-23 family; “YT” indicates tape-and-reel packaging; “215” relates to reel quantity).
- RoHS-compliant.
Applications: direct-drive logic interfacing, LED indicators, small relays, and simple switch-driving without external resistors. For exact electrical specs (Ic, Vce, rB, etc.) check the specific datasheet for the PDTC114YT variant you have.

PDTC114YT,215 is a 3‑pin SOT‑23 digital NPN transistor. Pin assignments (viewed from front, leads down):
- Pin 1: Base (internal series/base‑bias resistor)
- Pin 2: Collector
- Pin 3: Emitter (reference/return)
Function: it’s an NPN switching transistor with an integrated base resistor (digital transistor) for simplified drive (direct logic‑level input to Pin 1), Pin 2 is the switched output/collector, and Pin 3 is the emitter/ground.
