Product details
Overview
PDTB113EUF from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, designed for digital switching applications with built-in 1 kΩ input and 1 kΩ base-emitter bias resistors, −50 V VCEO, −500 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTB113EUF datasheet, PDTB113EUF pinout, PDTB113EUF application, or PDTB113EUF equivalent, this device serves as a space- and BOM-optimized replacement for discrete BJT + resistor networks in logic-level load switching, microcontroller I/O interfacing, and high-temperature industrial control circuits.
Technical Context
This RET integrates a PNP bipolar transistor with two monolithically embedded precision resistors: R1 (input bias) and R2 (base-emitter feedback), enabling single-pin digital drive without external components. Its ±10% R2/R1 ratio tolerance ensures predictable turn-on/off thresholds across temperature.
Rated for operation from −55 °C to +175 °C ambient and qualified to AEC-Q101, it supports robust switching in engine control units, body electronics, and under-hood power management where thermal stability and reliability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive and industrial supply rails with margin. |
| IO | −500 mA - Continuous output current capability; supports driving medium-power loads like relays, LEDs, and small solenoids. |
| R1 / R2 | 1 kΩ / 1 kΩ - Integrated bias network eliminates external resistors; reduces PCB area and assembly cost in digital interface designs. |
| hFE | 33 (min) at IC = −50 mA - DC current gain sufficient for saturated switching with low base drive current (e.g., 2.5 mA for 50 mA load). |
| VCE(sat) | −100 mV (max) at IC = −50 mA, IB = −2.5 mA - Low saturation voltage minimizes conduction loss and self-heating in high-duty-cycle operation. |
| Tj max | +175 °C - Junction temperature rating allows reliable operation in under-hood and enclosed industrial environments without derating. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: ultra-compact 3-lead outline measuring 2.2 × 1.35 × 0.95 mm (L × W × H), optimized for high-density PCB layouts and reflow-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level drive signal (e.g., MCU GPIO); no external base resistor required. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides return path for load current and bias network reference. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., relay coil anode or LED cathode) referenced to positive rail. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, and ESD testing - suitable for safety-critical non-safety systems (e.g., lighting, HVAC). |
| ±10% R2/R1 tolerance | Ensures consistent VI(on)/VI(off) thresholds across production lots, reducing need for system-level calibration or margining. |
| 175 °C junction rating | Enables uninterrupted operation in sealed enclosures or near heat sources without thermal shutdown or parameter drift. |
| Reduced component count | Replaces one BJT + two resistors; cuts BOM line items, placement time, and solder joint risk in automated assembly. |
Applications
| Automotive Lighting Control | Industrial PLC Output Stage |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTB113ZUF | R2 = 10 kΩ (vs. 1 kΩ), R2/R1 = 10; higher VI(off) (−1.0 V typ) and lower IEBO (−0.8 mA max). | Better noise immunity in noisy environments; suited for higher-impedance logic drivers (e.g., open-drain I²C buffers). | Select when system requires higher off-state input threshold or operates with weak-drive sources. |
| BC807-40,215 | Discrete PNP BJT only; requires external 1 kΩ base resistor; no integrated R2; hFE = 250–600 (wider spread). | Higher design flexibility but increases BOM count, layout area, and calibration effort for consistent switching. | Choose only if precise R2/R1 ratio control is unnecessary and manual resistor selection is acceptable. |
Compared with PDTB113ZUF, PDTB113EUF offers tighter R2/R1 matching (1.0 vs. 10.0) for predictable VI(on)/VI(off), while BC807-40 demands external biasing and lacks AEC-Q101 validation - making PDTB113EUF optimal for automotive and space-constrained industrial designs requiring zero-resistor integration.

FAQ
What is the maximum operating temperature for PDTB113EUF?
The PDTB113EUF is rated for junction temperatures up to +175 °C and ambient operation from −55 °C to +175 °C. Its thermal resistance Rth(j-a) is 353 K/W on a 4-layer FR4 PCB, enabling sustained operation in under-hood automotive locations and sealed industrial enclosures without active cooling.
Can PDTB113EUF replace BC807-40 in existing designs?
Yes - PDTB113EUF provides pin-compatible functionality with BC807-40 in high-side switching roles, but adds integrated 1 kΩ R1 and R2 resistors. It simplifies layout by eliminating two external components and improves consistency in VI(on)/VI(off) due to matched on-chip resistors, though base drive voltage range differs slightly (−1.4 V typ vs. −0.7 V for BC807).
Is PDTB113EUF suitable for PWM-driven loads?
Yes - with fT = 140 MHz and low VCE(sat), PDTB113EUF supports PWM frequencies up to several hundred kHz in saturated switching mode. Its fast turn-on/off characteristics (verified in datasheet Figures 4–7) ensure minimal switching loss when driving LEDs or small motors with duty cycles down to 1%.
Does PDTB113EUF require a pull-down resistor on the input pin?
No - the integrated R2 (1 kΩ) from base to emitter provides inherent pull-down functionality. When the input (Pin 1) is left floating or driven high-impedance, R2 ensures the transistor remains fully off, eliminating risk of unintended conduction and removing need for external pull-down components.
