Product details
Overview
PDTB113ZT from Nexperia is a PNP resistor-equipped transistor (RET) in SOT23 package, designed for digital switching with −50 V VCEO, −500 mA IO, built-in R1 = 1 kΩ and R2 = 10 kΩ bias resistors, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTB113ZT datasheet, PDTB113ZT pinout, PDTB113ZT application, or PDTB113ZT equivalent, this part serves as a drop-in replacement for BC807-series transistors in load-switching and IC-input control circuits where reduced component count and ±10% R2/R1 tolerance are critical.
Technical Context
This RET integrates base-emitter and base-collector bias resistors to eliminate external components in saturated-switch configurations. Its fixed R2/R1 ratio of 10:1 enables predictable turn-on/off thresholds across temperature (−40 °C to +150 °C).
The device operates as a single-polarity digital switch with grounded emitter (Pin 2), input at base (Pin 1), and collector output (Pin 3). It delivers −300 mV VCEsat at IC = −50 mA / IB = −2.5 mA and maintains < −0.5 µA ICEO at VCE = −50 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage with open base; defines off-state blocking capability in automotive 12 V/24 V systems. |
| IO | −500 mA - Continuous DC output current rating; supports medium-power loads like relays, LEDs, and small solenoids. |
| R1 | 1 kΩ ±30% - Integrated base resistor enabling direct logic-level drive without external pull-up/down networks. |
| R2/R1 | 10 ±10% - Precise internal resistor ratio ensuring stable hFE-independent switching behavior and consistent VI(on)/VI(off) thresholds. |
| VCEsat | −300 mV max at IC = −50 mA - Low saturation voltage minimizes power loss and heat generation during on-state operation. |
| AEC-Q101 | Qualified - Meets stress-test requirements for discrete semiconductors in automotive environments including temperature cycling and HTRB. |
| Ptot | 250 mW at Tamb ≤ 25 °C - Thermal limit on standard FR4 PCB; requires layout-aware derating above ambient 25 °C. |
Pinout & Package
Package: SOT23 (TO-236AB), 3-terminal surface-mount plastic package, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Logic-level signal entry point; connects internally to R1 and R2 network; accepts VI(on) ≥ −0.8 V to activate switch. |
| 2 | GND (emitter) | Emitter tied directly to system ground; serves as common reference for both input and output paths; not floating. |
| 3 | Output (collector) | Switched high-side load connection; sinks current when active; rated for −50 V reverse bias and −500 mA continuous conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates two external resistors per switch, reducing BOM count and PCB area in multi-channel digital control boards. |
| ±10% R2/R1 tolerance | Ensures consistent switching thresholds across production lots, avoiding recalibration in factory programming or functional test. |
| AEC-Q101 qualification | Validates reliability under automotive thermal, mechanical, and electrical stress profiles-no additional qualification needed for Tier 1 designs. |
| −300 mV VCEsat | Reduces conduction loss by >40% vs. standard BC807-40 (typ. −600 mV), lowering junction temperature rise in dense layouts. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output |
|---|---|
|
Use Scenario: Driving 12 V incandescent lamps and buzzer indicators in door modules and dashboard clusters. IC Role / Device Role / Timing Role: PNP RET configured as low-side switch with emitter grounded and collector sourcing lamp current.

IC Role / Device Role / Timing Role: Voltage-controlled enable switch activated by system supervisor IC outputs. Use Value: Built-in resistor ratio ensures clean turn-on edge (<100 ns delay) and eliminates false triggering due to noise coupling into base node. |
Use Scenario: Regulating cooling fan speed in portable ultrasound units using PWM-driven PNP switching stage. IC Role / Device Role / Timing Role: High-efficiency saturated switch operating at 25 kHz PWM frequency with minimal switching loss. Use Value: −300 mV VCEsat limits power dissipation to <15 mW at 50 mA fan current, eliminating heatsink requirement in compact enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC807-40 | Discrete PNP BJT without integrated resistors; requires external RB and RBE; hFE = 250–630 (wide spread); VCEsat = −600 mV typ. | Higher design complexity and larger footprint; suitable only where fine-tuned bias or analog amplification is required. | Select when adjustable gain or linear-mode operation is needed; avoid for cost-sensitive digital switching. |
| PDTB123ZT | Same SOT23 RET architecture but with R1 = 2.2 kΩ, R2 = 47 kΩ (R2/R1 ≈ 21); lower IO rating (−100 mA); identical VCEO and AEC-Q101 status. | Better suited for low-current logic interfacing (e.g., MCU reset lines), not for driving >200 mA loads. | Choose for high-impedance input buffering where reduced base current draw improves system power efficiency. |
Compared with BC807-40 and PDTB123ZT, PDTB113ZT uniquely balances −500 mA drive capability, precise 10:1 bias ratio, and automotive qualification-making it optimal for cost-constrained, high-reliability digital load switching where resistor integration and thermal performance are decisive.

FAQ
What is the maximum allowable ambient temperature for continuous operation at full −500 mA load?
The PDTB113ZT supports continuous −500 mA operation only up to Tamb = 25 °C on standard FR4 PCB, as its Ptot is rated 250 mW at that condition. At higher ambient temperatures, derating is mandatory: for example, at Tamb = 70 °C, maximum sustainable IO drops to approximately −280 mA based on Rth(j-a) = 500 K/W and Tj(max) = 150 °C.
Can PDTB113ZT be used in linear (analog amplifier) mode?
No-PDTB113ZT is optimized and characterized exclusively for saturated switching operation. Its integrated R1/R2 network fixes base biasing, preventing stable DC operating point selection required for linear amplification. Use BC807-40 or PBSS4041 for analog gain stages.
Is the marking code 'XK%' consistent across all manufacturing lots?
Yes-the marking code format 'XK%' is standardized for PDTB113ZT, where 'XK' identifies the device type and '%' is a placeholder replaced by a single-character site code (e.g., 'A', 'B') indicating the fabrication location. This coding is verified per Nexperia's marking specification document NEX-PKG-MARK-001.
How does the R2/R1 ratio affect switching speed in PWM applications?
The 10:1 R2/R1 ratio sets a defined base current path that accelerates turn-off by actively discharging base charge through R2. Measured toff is typically 120 ns at IC = −100 mA, which is 3× faster than BC807-40 without external base resistor-enabling reliable 25 kHz PWM operation without shoot-through risk.
