Product details
Overview
PDTD114EU135 from Nexperia is a 50 V, 500 mA NPN resistor-equipped transistor (RET) in SOT323 (SC-70) package, featuring integrated 10 kΩ input bias resistor (R1) and 10 kΩ base-emitter resistor (R2) with ±10% ratio tolerance. It operates up to 175 °C ambient, supports IC-level digital switching, and replaces discrete BJT + resistor networks in compact load-switching applications.
For engineers reviewing the PDTD114EU135 datasheet, PDTD114EU135 pinout, PDTD114EU135 application, or PDTD114EU135 equivalent, this page delivers verified electrical specs, thermal derating curves, AEC-Q101 qualification status, and direct alternatives for automotive-grade digital interface design.
Technical Context
This RET integrates a silicon NPN transistor with two precision thin-film resistors on a single die: R1 connects the input terminal to the base, and R2 shunts base to emitter. The fixed R2/R1 ratio of 1.0 ±10% ensures stable turn-on/turn-off thresholds across temperature.
It functions as a single-stage digital switch-accepting TTL/CMOS-compatible logic inputs (VI(on) = 1.0–3.0 V, VI(off) = 0.6–1.5 V), delivering low-saturation performance (VCEsat ≤ 100 mV at IC = 50 mA, IB = 2.5 mA), and supporting high-temperature operation up to 175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V industrial and 12 V automotive supply rails with margin. |
| IO | 500 mA - Continuous DC output current capability; sufficient for driving relays, LEDs, small solenoids, or logic-level fan loads. |
| R1 | 10 kΩ - Input bias resistor value; sets base current for defined saturation under standard logic drive conditions. |
| R2 | 10 kΩ - Base-emitter resistor value; provides reliable turn-off by shunting leakage and ensuring VBE stays below threshold. |
| R2/R1 ratio | 1.0 ±10% - Tight resistor matching ensures consistent VI(on)/VI(off) hysteresis and robust noise immunity in noisy environments. |
| Tj max | 175 °C - Maximum junction temperature; supports operation in under-hood automotive or high-ambient industrial enclosures. |
| hFE | 70 (min) - DC current gain at VCE = 5 V, IC = 50 mA; guarantees forced beta ≥20 in typical switching configurations. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.35 mm × 1.15 mm × 0.95 mm body, 0.65 mm lead pitch, 3-terminal configuration with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level control signal; requires no external base resistor. |
| 2 | GND (emitter) | Emitter reference node; tied to system ground; serves as common return path for load current. |
| 3 | output (collector) | Switched high-side output node; connects to load anode (for low-side switch) or load cathode (for high-side switch with pull-up). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates need for two external resistors, reducing PCB area by >30% versus discrete BJT + R1 + R2 solutions. |
| AEC-Q101 qualified | Validated for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces. |
| High-temp operation | Rated for continuous operation at Tamb = −55 °C to +175 °C; suitable for under-dash, powertrain, and battery management systems. |
| Low VCEsat | ≤100 mV at IC = 50 mA ensures <5 mW conduction loss per switch, critical for thermally constrained designs. |
| ±10% R2/R1 tolerance | Guarantees predictable VI(on) and VI(off) thresholds across production lots and temperature, simplifying logic-level interface validation. |

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 |
|---|---|---|---|
| BC807-40,215 | Discrete BJT without built-in resistors; requires external R1 and R2; hFE = 250–630; VCEO = 45 V. | Higher gain but needs additional passives; not AEC-Q101 qualified; unsuitable for space-constrained automotive PCBs. | Select only if higher hFE or lower VCEsat (<80 mV) is required and board area permits two extra 0402 resistors. |
| PDTB114EU | PNP complement in same SOT323 package; identical R1/R2 values (10 kΩ/10 kΩ); VCEO = −50 V; IO = −500 mA. | Used for high-side switching or push-pull configurations; shares footprint and thermal profile but opposite polarity. | Choose when designing complementary driver pairs for H-bridge motor control or dual-rail logic level translation. |

FAQ
What is the maximum ambient temperature for continuous operation of PDTD114EU135?
PDTD114EU135 is rated for continuous operation from −55 °C to +175 °C ambient temperature. Its 175 °C junction rating allows full 500 mA output current at +105 °C ambient on a 4-layer FR4 PCB, with derating applied above that per the published thermal resistance curve (Rth(j-a) = 353 K/W).
Does PDTD114EU135 require an external base resistor?
No, PDTD114EU135 does not require an external base resistor. It integrates a 10 kΩ input resistor (R1) and a 10 kΩ base-emitter resistor (R2), forming a complete bias network. This eliminates the need for external components and ensures consistent VI(on) and VI(off) thresholds across temperature and process variation.
Is PDTD114EU135 qualified for automotive applications?
Yes, PDTD114EU135 is AEC-Q101 qualified for discrete semiconductors. It has passed stress tests including HTGB, HTRB, and temperature cycling, making it suitable for automotive body electronics, infotainment systems, and ADAS sensor interfaces where reliability and extended temperature range are mandatory.
What is the typical transition frequency (fT) of PDTD114EU135?
The typical transition frequency (fT) of PDTD114EU135 is 225 MHz at VCE = 5 V and IC = 50 mA. This high fT supports fast switching in PWM-driven loads and digital interface applications up to several hundred kHz without significant gain roll-off.
How does the R2/R1 ratio affect switching behavior in PDTD114EU135?
The R2/R1 ratio of 1.0 ±10% in PDTD114EU135 directly determines the input hysteresis window: VI(on) ≈ 1.9 V and VI(off) ≈ 1.0 V at 25 °C. This tight ratio ensures stable turn-on/turn-off thresholds across temperature, minimizing false triggering in electrically noisy automotive or industrial environments.
