Product details
Overview
PDTB113ZUF 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 bias resistor (R1) and 10 kΩ base-emitter resistor (R2), ±10% resistor ratio tolerance, −50 V VCEO, −500 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTB113ZUF datasheet, PDTB113ZUF pinout, PDTB113ZUF application, or PDTB113ZUF equivalent, key selection criteria include its integrated bias network, high-temperature operation up to 175 °C, low VCE(sat) of −100 mV at −50 mA/−2.5 mA, and compatibility with 5 V logic-level control in space-constrained PCB layouts.
Technical Context
This RET integrates a PNP bipolar transistor with two precision on-die resistors: R1 (1 kΩ) connects input to base, and R2 (10 kΩ) connects base to emitter, enabling single-resistor drive from microcontroller GPIOs. The R2/R1 ratio of 10 provides stable current gain control and reduces external component count.
It operates across −55 °C to +175 °C ambient, supports 300 mW power dissipation on FR4 single-layer PCB, and delivers hFE = 70 at −50 mA/−5 V, making it suitable for robust digital load switching where thermal resilience and simplified layout 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 supply rails with margin. |
| IO | −500 mA - Continuous output current capability; supports driving medium-power relays or LEDs directly. |
| R1 / R2 | 1 kΩ / 10 kΩ - Fixed internal bias network eliminates external resistors; simplifies PCB layout and improves production yield. |
| VCE(sat) | −100 mV @ −50 mA/−2.5 mA - Low saturation voltage minimizes power loss and self-heating during switching. |
| hFE | 70 @ −50 mA/−5 V - DC current gain ensures reliable turn-on with standard logic-level drive without additional amplification. |
| Tj(max) | 175 °C - Junction temperature rating supports operation in under-hood automotive environments and industrial enclosures. |
| AEC-Q101 | Qualified - Meets stress-test requirements for discrete semiconductors in automotive applications; validated for reliability over lifetime. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.35 mm × 1.15 mm × 0.45 mm body, 3-pin configuration with gull-wing leads, optimized for reflow soldering on high-density PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level voltage to enable transistor conduction. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for load return path. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., relay coil, LED anode) referenced to positive rail. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates need for two external resistors, reducing BOM count and layout area by ~3 mm² per instance. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, temperature cycling, and ESD testing per JESD22-A110/A114. |
| High-temperature operation | Full functionality maintained from −55 °C to +175 °C ambient, supporting engine control and powertrain modules. |
| Low VCE(sat) | −100 mV at rated current ensures <10 mW conduction loss, critical for thermally constrained modules. |
| Resistor ratio tolerance | ±10% R2/R1 matching guarantees consistent turn-on threshold across production lots and temperature ranges. |
Applications
| Automotive Door Module | Industrial PLC Output Stage |
|---|---|
Use Scenario: Controlling window lift motors and mirror actuators in door control units. IC Role / Device Role / Timing Role: PNP RET acts as high-side switch for 12 V loads, driven directly by MCU GPIO without level-shifting.

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 |
|---|---|---|---|
| PDTB113EU | R2 = 1 kΩ (R2/R1 = 1.0); lower off-state input voltage (−1.5 V) and higher hFE variation. | Better suited for general-purpose digital switching where tighter VI(off) is required. | Select when needing matched R1/R2 for symmetric bias or higher gain consistency at low currents. |
| PDTD113ZU | NPN complement; same R1/R2 values but opposite polarity; requires inverted logic drive. | Used in low-side switching configurations where emitter is grounded and collector drives load to VCC. | Choose for NPN-based designs or when integrating with existing NPN RET footprints and drive architecture. |
Compared with PDTB113EU, PDTB113ZUF offers higher noise immunity due to its 10× R2/R1 ratio, while versus PDTD113ZU it enables high-side switching without level-shifting-critical for automotive battery-referenced loads.

FAQ
What is the maximum continuous collector current for PDTB113ZUF?
The maximum continuous output current is −500 mA, verified under standard test conditions (Tamb ≤ 25 °C, FR4 PCB with single-sided copper). Derating applies above 25 °C ambient per the published power derating curve, reaching zero at 125 °C for 300 mW-rated operation.
Does PDTB113ZUF require external bias resistors?
No. It integrates both R1 (1 kΩ) and R2 (10 kΩ) on-die, forming a complete bias network. This eliminates the need for external resistors, reduces PCB footprint, and improves manufacturing yield-confirmed in the device's "Simplifies circuit design" feature list and pinning diagram.
Is PDTB113ZUF compatible with 3.3 V microcontroller GPIOs?
Yes. Its VI(on) is −0.4 V (min) to −1.4 V (max) at −20 mA, ensuring reliable turn-on with 3.3 V logic outputs. The −0.8 V typical VI(on) falls well within the valid low-state range of most 3.3 V MCUs, and its −0.3 V VI(off) threshold provides noise margin against false triggering.
How does PDTB113ZUF differ from BC807 in practical design?
Unlike BC807-a bare PNP transistor requiring two external bias resistors-PDTB113ZUF integrates them, reducing component count, layout area, and assembly cost. It also adds AEC-Q101 qualification, 175 °C junction rating, and tighter resistor ratio tolerance (±10%), making it suitable for automotive and high-reliability industrial use where BC807 would require additional validation.
