Product details
Overview
PDTC114YK,115 from NXP Semiconductors is an NPN resistor-equipped transistor (RET) in SOT23 package, designed for digital switching applications with built-in bias resistors R1 = 10 kΩ and R2 = 47 kΩ, 50 V VCEO, 100 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTC114YK,115 datasheet, PDTC114YK,115 pinout, PDTC114YK,115 application, or PDTC114YK,115 equivalent, this part serves as a space- and cost-optimized replacement for discrete BJT + resistor networks in IC input control and load switching circuits where simplified layout and reduced component count are critical.
Technical Context
This NPN RET integrates two precision bias resistors (R1 = 10 kΩ, R2/R1 = 4.7) directly into the SOT23 package to eliminate external base resistors. Its internal topology enables direct logic-level drive without additional components while maintaining stable saturation behavior across temperature.
The device operates as a single-pole switch with defined VI(on) = 0.8–1.4 V and VI(off) = 0.5–0.7 V thresholds, supporting reliable turn-on/turn-off in 3.3 V and 5 V digital systems. It delivers 100 mA output current capability with VCE(sat) ≤ 100 mV at IC = 5 mA / IB = 0.25 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V maximum - supports robust operation in 24 V automotive and industrial supply rails with margin. |
| IO | 100 mA continuous - sufficient for driving LED indicators, small relays, and logic inputs. |
| R1 | 10 kΩ ±30% - sets base current for predictable turn-on with standard microcontroller GPIOs. |
| R2/R1 | 4.7 typical - ensures stable bias network ratio for consistent hFE-independent switching behavior. |
| VCE(sat) | ≤100 mV at IC = 5 mA - minimizes power loss and self-heating during active conduction. |
| VI(on) | 0.8–1.4 V - compatible with TTL and CMOS logic families without level-shifting. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD. |
Pinout & Package
SOT23 plastic surface-mounted package (TO-236AB), 3-lead, body dimensions 2.9 × 1.3 × 1.0 mm; suitable for reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level control signal directly from MCU or gate driver. |
| 2 | GND (emitter) | Common reference node; ties emitter to ground or low-side return path. |
| 3 | output (collector) | Switched high-side output node; connects to load (e.g., LED anode or relay coil) referenced to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in R1/R2 bias network | Eliminates two external resistors, reducing PCB area and assembly steps in digital interface designs. |
| 100 mA output current rating | Enables direct drive of moderate-current loads without external amplification stages. |
| AEC-Q101 qualification | Validated for automotive under-hood and infotainment applications requiring extended temperature and reliability compliance. |
| Low VCE(sat) ≤ 100 mV | Reduces conduction losses and thermal stress in battery-powered or thermally constrained systems. |
| Logic-compatible VI(on)/VI(off) | Ensures clean switching with standard 3.3 V/5 V digital outputs without external pull-ups or level shifters. |
Applications
| Automotive LED Lighting Control | Industrial Digital Input Conditioning |
|---|---|
Use Scenario: Driving indicator LEDs in dashboard clusters or exterior lighting modules. IC Role / Device Role / Timing Role: NPN switch controlling LED current path between VCC and ground.

Use Value: VI(on)/VI(off) thresholds and hFE stability ensure reliable detection of 24 V on/off states even with voltage ripple or EMI. |
| Consumer Appliance Load Switching | IoT Device Power Management |
Use Scenario: Enabling/disabling solenoids, buzzers, or small fans in white goods and home appliances. IC Role / Device Role / Timing Role: Low-side switch controlled by appliance main controller. Use Value: 100 mA rating and 50 V VCEO support common 12–24 V appliance rails; AEC-Q101 qualification adds long-term reliability assurance. |
Use Scenario: Managing power to peripheral sensors or radios in battery-operated smart devices. IC Role / Device Role / Timing Role: Discrete load switch enabling software-controlled power gating. Use Value: Low VCE(sat) minimizes quiescent loss during active state; compact SOT23 footprint conserves PCB real estate in miniaturized IoT designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC114YT,215 | Same electrical specs and SOT23 package; differs only in packing code (-215 vs -115) and marking (*27 vs K). | Identical functional use; both rated for automotive and industrial switching. | Select PDTC114YT,215 when tape-and-reel packaging with 3000-unit reels is required. |
| BC847B,215 | Standard NPN BJT without integrated resistors; requires two external bias resistors for same function. | Higher component count and layout complexity; not AEC-Q101 qualified. | Choose BC847B,215 only if discrete bias tuning is needed or legacy design reuse mandates non-RET topology. |
Compared with PDTC114YT,215, the PDTC114YK,115 offers identical performance but distinct manufacturing traceability via 'K' marking; versus BC847B,215, it reduces bill-of-materials and improves production yield by integrating biasing, albeit with fixed R1/R2 values.

FAQ
What is the package type and footprint compatibility of PDTC114YK,115?
The PDTC114YK,115 uses the SOT23 (TO-236AB) package with standard 2.9 mm × 1.3 mm outline and 0.95 mm pitch. Its footprint matches JEDEC TO-236AB specifications and is compatible with reflow soldering processes per NXP's recommended profile. No wave soldering is advised. The PDTC114YK,115 shares mechanical compatibility with other SOT23-based transistors but requires verification of pin 1 orientation and thermal pad clearance per layout guidelines.
Is PDTC114YK,115 suitable for automotive applications?
Yes, PDTC114YK,115 is AEC-Q101 qualified for automotive use, having passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per JS-001. Its operating ambient temperature range of −65 °C to +150 °C and junction temperature limit of 150 °C support under-hood and infotainment module deployment. The PDTC114YK,115 meets automotive reliability requirements without derating in most 12 V/24 V systems.
What are the key electrical differences between PDTC114YK,115 and PDTC114YT,215?
PDTC114YK,115 and PDTC114YT,215 share identical electrical specifications, thermal characteristics, and SOT23 package dimensions. The difference lies solely in ordering code suffixes (−115 vs −215) and top-side marking ('K' vs '*27'), reflecting different reel packaging quantities and manufacturing lot traceability. Both parts are functionally interchangeable in circuit design and layout; no electrical or mechanical redesign is needed when substituting PDTC114YK,115 for PDTC114YT,215.
Can PDTC114YK,115 replace BC847-series transistors directly?
PDTC114YK,115 serves as a cost-saving alternative to BC847/857-series BJTs in digital switching applications, but it is not a pin-to-pin drop-in replacement due to integrated bias resistors. While both use SOT23 packages, the PDTC114YK,115 has internal R1/R2 connections that eliminate external base resistors - meaning existing BC847 layouts require modification to remove those resistors and reroute base drive. The PDTC114YK,115 simplifies new designs but is not a direct PCB swap for legacy BC847 footprints.
What is the maximum power dissipation of PDTC114YK,115 at room temperature?
At Tamb ≤ 25 °C, the PDTC114YK,115 has a total power dissipation (Ptot) rating of 250 mW when mounted on an FR4 PCB with standard footprint. This value decreases linearly above 25 °C per the derating curve in Figure 1, reaching zero at approximately 150 °C ambient. Actual dissipation must be calculated using VCE(sat) × IC in saturation and verified against thermal resistance Rth(j-a) = 500 K/W to ensure junction temperature remains below 150 °C.
