Product details
Overview
PDTA124XQB from Nexperia is a 50 V, 100 mA PNP resistor-equipped transistor (RET) in a DFN1110D-3 (SOT8015) leadless SMD package with side-wettable flanks. It integrates R1 = 22 kΩ and R2 = 47 kΩ bias resistors, delivers hFE = 80 at IC = −5 mA / VCE = −5 V, and achieves VCE(sat) ≤ −100 mV at IC = −10 mA / IB = −0.5 mA - used for digital switching of logic-level inputs and low-power load control in space-constrained PCBs.
For engineers reviewing the PDTA124XQB datasheet, PDTA124XQB pinout, PDTA124XQB application, or PDTA124XQB equivalent, this page provides verified electrical parameters, validated pin functions, confirmed SOT8015 package dimensions, AOI-compatible solder joint geometry, and direct alternatives for PNP RET-based level translation and discrete gate driving.
Technical Context
This PNP RET implements a monolithic silicon transistor with two integrated precision thin-film resistors: R1 (22 kΩ) connects base to input, R2 (47 kΩ) connects base to emitter. The internal topology enables single-resistor external drive while maintaining predictable VI(on) (−2.0 to −1.1 V) and VI(off) (−0.8 to −0.5 V) thresholds across temperature.
Its DFN1110D-3 package features 0.65 mm pitch, 1.1 × 1.0 × 0.48 mm body, and side-wettable flanks for automated optical inspection of solder joints - optimized for high-density routing and reflow compatibility on FR4 PCBs with 35–70 µm copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - maximum collector-emitter voltage before breakdown; supports rail-to-rail switching in 3.3 V/5 V logic interfaces. |
| IO | −100 mA - continuous output current capability; sufficient for driving LED indicators, small relays, or MCU GPIO inputs. |
| hFE | 80 @ VCE = −5 V, IC = −5 mA - DC current gain enabling reliable saturation with minimal base drive current. |
| VCE(sat) | ≤ −100 mV @ IC = −10 mA, IB = −0.5 mA - ultra-low saturation voltage minimizes power loss in active-switching applications. |
| R1/R2 | 22 kΩ / 47 kΩ - fixed internal bias network simplifies PCB layout and eliminates need for two external resistors. |
| Tj(max) | 150 °C - maximum junction temperature; allows operation in industrial ambient environments up to +125 °C with derating. |
Pinout & Package
DFN1110D-3 (SOT8015) is an ultra-thin, leadless surface-mount package measuring 1.1 mm × 1.0 mm × 0.48 mm with side-wettable flanks for AOI-compatible solder joint inspection. Pitch is 0.65 mm; thermal pad is absent - thermal dissipation relies on trace conduction via pins 1 and 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to external control signal; internally tied to R1 (22 kΩ) and R2 (47 kΩ) node - defines VI(on)/VI(off) thresholds. |
| 2 | GND (emitter) | Emitter terminal and reference ground for internal resistors; must be connected to system GND for proper biasing and current return path. |
| 3 | Output (collector) | Switched output node; sinks current when active; rated for −50 V VCEO and −100 mA continuous load. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic 22 kΩ + 47 kΩ resistor pair eliminates two external components and reduces BOM count by 2×. |
| AOI-compatible packaging | Side-wettable flanks on DFN1110D-3 enable automated optical inspection of solder fillets without X-ray. |
| Low profile height | 0.48 mm max body height - fits under low-clearance shields and supports ultra-thin portable device designs. |
| Thermal robustness | Rth(j-a) = 298 K/W (70 µm Cu) - enables 420 mW power dissipation on standard FR4, supporting sustained 100 mA switching. |
Applications
| Logic-Level Translation | Digital Input Conditioning |
|---|---|
Use Scenario: Converting 3.3 V microcontroller outputs to interface with 5 V legacy peripherals. IC Role / Device Role / Timing Role: PNP RET acts as an active-low level shifter with defined VI(on)/VI(off) thresholds and fast turn-on/turn-off. Use Value: Eliminates need for dual-supply translators; supports >1 MHz toggle rates with <100 ns propagation delay. |
Use Scenario: Debouncing mechanical switch signals before feeding into FPGA or MCU interrupt pins. IC Role / Device Role / Timing Role: Provides clean, noise-immune digital input conditioning with hysteresis-like behavior via resistor ratio. Use Value: Reduces ESD susceptibility and false triggering; replaces RC + Schmitt trigger discrete solution. |
| LED Driver Interface | Small-Load Switching |
Use Scenario: Driving common-anode status LEDs from open-drain or push-pull GPIOs. IC Role / Device Role / Timing Role: Functions as a low-side sink switch with controlled saturation voltage and current limiting. Use Value: Ensures consistent LED brightness across supply variations; avoids GPIO overcurrent stress. |
Use Scenario: Enabling/disabling 5 V sensor modules or communication transceivers in battery-powered IoT nodes. IC Role / Device Role / Timing Role: High-efficiency load switch with <100 mV dropout and fast enable/disable response. Use Value: Minimizes standby power loss; supports rapid power cycling without inrush current spikes. |
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 |
|---|---|---|---|
| PDTC124XQB | NPN complement with identical R1/R2 values (22 kΩ/47 kΩ), same SOT8015 package, but opposite polarity. | Requires inverted logic drive and sourcing (not sinking) output configuration. | Select when circuit uses NPN-based pull-up architecture or requires complementary switching pairs. |
| PDTA123JQB | Same PNP RET topology but R1 = 2.2 kΩ / R2 = 47 kΩ → lower VI(on) threshold (−1.1 V typ) and higher hFE (100). | Better suited for 1.8 V logic interfaces; less suitable for 3.3 V+ systems due to reduced noise margin. | Choose for ultra-low-voltage digital control where tighter input threshold control is required. |
Compared with PDTC124XQB, PDTA124XQB provides sinking output capability ideal for active-low signaling; versus PDTA123JQB, it offers higher input impedance and improved noise immunity at 3.3 V logic levels - making it optimal for mixed-voltage industrial I/O.

FAQ
What is the maximum allowable input voltage (VI) for PDTA124XQB?
The absolute maximum input voltage is −40 V to +7 V, per Table 6. However, functional operation is guaranteed only within VI(on) = −2.0 to −1.1 V (active state) and VI(off) = −0.8 to −0.5 V (inactive state) at VCE = −5 V and IC = −100 µA. Exceeding these ranges risks unreliable switching or latch-up.
Can PDTA124XQB be used in analog amplifier configurations?
No - PDTA124XQB is designed exclusively for digital switching applications. Its integrated resistors fix the base bias point, eliminating external biasing flexibility. The hFE variation (80 typ, no min/max spec) and lack of linear-region characterization confirm its intended use as a saturated switch, not a linear amplifier.
Is thermal pad connection required for PDTA124XQB's DFN1110D-3 package?
No - the DFN1110D-3 package used for PDTA124XQB has no exposed thermal pad. Thermal performance relies entirely on conduction through pins 1 (input/base) and 2 (GND/emitter). Layout should maximize copper area connected to pin 2 for optimal heat dissipation.
How does PDTA124XQB compare to BC857 in digital applications?
PDTA124XQB replaces BC857 + two external resistors in digital switching roles, reducing component count by 2× and eliminating placement/pick-and-place steps. It offers identical VCEO (−50 V) and IO (−100 mA), plus built-in resistor matching and AOI-ready packaging - improving yield and reliability over discrete implementations.
