Product details
Overview
PDTB113ZUX from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, designed for digital switching applications requiring integrated biasing. It delivers −500 mA output current, features 1 kΩ input bias resistor (R1) and 10 kΩ base-emitter resistor (R2), and supports operation up to 175 °C ambient temperature - used in automotive body control modules for LED load switching.
For engineers reviewing the PDTB113ZUX datasheet, PDTB113ZUX pinout, PDTB113ZUX application, or PDTB113ZUX equivalent, key selection criteria include its ±10 % R2/R1 ratio tolerance, −5 V emitter-base voltage limit, −100 mV VCE(sat) at −50 mA/−2.5 mA, AEC-Q101 qualification, and compatibility with 3.3 V/5 V logic-level drive.
Technical Context
This device integrates a PNP bipolar transistor with two monolithic silicon resistors: R1 (1 kΩ) connects the input terminal to the base, and R2 (10 kΩ) connects base to emitter, enabling single-resistor logic interface without external bias components. Its −50 V VCEO rating and −500 mA IO capability support robust load switching in 12 V automotive subsystems.
The built-in resistor ratio (R2/R1 = 10) ensures stable turn-on/off thresholds across temperature (−55 °C to +175 °C), while its 140 MHz fT and 11 pF collector capacitance support fast digital transitions in low-power control nodes - critical for duty-cycled lighting and sensor interface circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter voltage before breakdown; enables use in 12 V automotive supply rails with margin. |
| IO | −500 mA: Continuous output current capacity; sufficient for driving high-brightness LEDs or small relays. |
| R1 | 1 kΩ: Input bias resistor value; sets base current when driven by standard CMOS/TTL logic outputs. |
| R2 | 10 kΩ: Base-emitter resistor; provides active pull-down for reliable turn-off and noise immunity. |
| VCE(sat) | −100 mV at IC = −50 mA, IB = −2.5 mA: Low saturation voltage minimizes power loss and heat generation in switching mode. |
| hFE | 70 (typ): DC current gain at VCE = −5 V, IC = −50 mA; ensures adequate current amplification for logic-driven loads. |
| VEBO | −5 V: Maximum reverse emitter-base voltage; defines safe operating range for negative transient suppression. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.3 mm × 1.8 mm footprint, 0.95 mm height, 3-terminal configuration with gull-wing leads optimized for reflow soldering on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base connection via R1) | Logic signal input node; internally connected to R1, which biases the transistor base. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common return path for load current. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode) and supply rail. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors | Eliminates need for two external resistors, reducing BOM count and PCB area in space-constrained modules. |
| AEC-Q101 qualification | Validated for automotive under-hood applications including temperature cycling, humidity, and mechanical shock testing. |
| High-temperature operation | Junction temperature rated to 175 °C, supporting placement near heat sources like power converters or motors. |
| ±10 % R2/R1 tolerance | Ensures consistent VI(on)/VI(off) thresholds across production lots, improving batch-to-batch reliability in digital interfaces. |
| Low VCE(sat) | −100 mV at rated current reduces conduction losses and thermal stress in continuous-duty switching applications. |

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 threshold (−1.5 V vs −1.0 V). | Better suited for higher-speed switching where faster turn-off is required. | Select when tighter R2/R1 matching is needed and VEBO ≥ −10 V is acceptable. |
| BC807-40 | Discrete PNP BJT without built-in resistors; requires external R1/R2; hFE = 250–630 (wider spread). | Higher gain but increased design complexity and board space; no AEC-Q101 qualification. | Choose only if custom biasing is required or cost-per-transistor is prioritized over design time savings. |
Compared with PDTB113ZUX, PDTB113EU offers faster switching due to matched R1/R2 but lacks the −5 V VEBO margin needed for noisy automotive environments; BC807-40 demands additional passives and validation effort, making it less suitable for AEC-Q101-compliant compact designs.

FAQ
What is the maximum allowable input voltage for PDTB113ZUX?
The absolute maximum input voltage (VI) is −10 V to +5 V, with typical on-state operation between −0.4 V and −1.4 V at IC = −20 mA. Exceeding +5 V risks damaging the internal R1 resistor or base-emitter junction; always limit drive signals to 3.3 V or 5 V logic levels with appropriate series resistance if interfacing with higher-voltage sources.
Can PDTB113ZUX replace BC807-40 directly in existing designs?
No direct replacement is possible without circuit modification: PDTB113ZUX has integrated 1 kΩ/10 kΩ bias resistors and operates as a single-input switch, whereas BC807-40 requires external base resistors. Layout changes and verification of VI(on)/VI(off) thresholds, thermal performance, and AEC-Q101 compliance are mandatory before substitution.
How does the R2/R1 = 10 ratio affect switching behavior?
An R2/R1 ratio of 10 ensures strong base-emitter pull-down relative to base drive, resulting in VI(off) = −1.0 V (typ) and sharp turn-off characteristics - critical for noise immunity in automotive CAN/LIN bus proximity. This ratio also stabilizes hFE across temperature, reducing gain variation versus discrete bias networks.
Is thermal derating required above 25 °C ambient?
Yes: total power dissipation drops from 425 mW (4-layer PCB) to 300 mW (single-layer PCB) at Tamb = 25 °C, and derates linearly to zero at 175 °C. For continuous −500 mA operation, keep junction temperature ≤175 °C using thermal vias, copper pour, or forced airflow - especially in sealed enclosures near power stages.
