Product details
Overview
PDTA124XQB-Q 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 VCE(sat) ≤ −100 mV at IC = −10 mA / IB = −0.5 mA, and supports automotive-grade operation per AEC-Q101. It functions as a compact, pre-biased switch for digital load control in space-constrained PCBs.
For engineers reviewing the PDTA124XQB-Q datasheet, PDTA124XQB-Q pinout, PDTA124XQB-Q application, or PDTA124XQB-Q equivalent, this device serves as a drop-in replacement for BC857-Q series transistors in low-power digital switching-where reduced component count, AOI-compatible solder joints, and −40 °C to +150 °C ambient operation are critical.
Technical Context
This PNP RET uses an integrated bipolar junction transistor with two on-die resistors: R1 (22 kΩ) connects base to input, and R2 (47 kΩ) connects base to emitter, enabling single-resistor drive and eliminating external bias networks. Its internal structure ensures predictable turn-on/off thresholds across temperature.
The device operates with VI(off) = −0.8 V to −0.5 V and VI(on) = −2.0 V to −1.1 V at IC = −2 mA, supporting TTL- and CMOS-level compatible digital inputs. Its 0.48 mm profile and side-wettable flanks facilitate automated optical inspection and high-density reflow assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage under open-base conditions; enables use in 24 V automotive and industrial supply rails. |
| IO | −100 mA - Continuous DC output current capability; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 / R2 | 22 kΩ / 47 kΩ - Precisely trimmed on-die resistors; eliminate need for external bias components and reduce BOM count by one. |
| VCE(sat) | ≤ −100 mV at IC = −10 mA, IB = −0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching applications. |
| hFE | 80 at VCE = −5 V, IC = −5 mA - Guaranteed DC current gain ensures reliable switching margin with standard logic drive levels. |
| Tj(max) | 150 °C - Junction temperature limit aligned with AEC-Q101 automotive qualification; supports under-hood and engine-control module deployment. |
| Package | DFN1110D-3 (SOT8015) - 1.1 × 1.0 × 0.48 mm ultra-thin leadless package with side-wettable flanks for AOI-capable solder joint verification. |
Pinout & Package

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-Q | NPN complement with identical R1/R2 values (22 kΩ/47 kΩ), same package and AEC-Q101 rating. | Requires inverted logic drive and high-side load placement; not interchangeable without circuit redesign. | Select when sourcing complementary NPN/PNP pairs for push-pull or H-bridge driver stages. |
| BC857B-Q | Discrete PNP transistor without built-in resistors; requires external 22 kΩ base resistor for equivalent biasing. | Higher BOM count and larger footprint; lacks side-wettable flanks and AOI support. | Choose only if legacy board reuse mandates discrete topology or if tighter hFE tolerance (160–450) is required. |
Compared with PDTC124XQB-Q, PDTA124XQB-Q provides native PNP polarity for direct MCU sink-drive; compared with BC857B-Q, it reduces component count by one resistor and improves manufacturability via AOI-ready packaging.

FAQ
What is the maximum operating temperature for PDTA124XQB-Q?
The device is rated for junction temperatures up to 150 °C and ambient temperatures from −55 °C to +150 °C. Its thermal resistance is 298 K/W on a 70 µm copper FR4 PCB, enabling full 100 mA output current at 100 °C ambient when properly heatsinked via PCB copper pour.
Can PDTA124XQB-Q replace BC857B-Q without circuit changes?
No-PDTA124XQB-Q integrates R1 and R2 bias resistors, while BC857B-Q is a bare transistor requiring an external base resistor. Direct substitution would cause incorrect biasing and potential saturation failure. A redesign removing the external resistor is required for functional equivalence.
Is side-wettable flank inspection supported for this package?
Yes-the DFN1110D-3 (SOT8015) package features side-wettable flanks designed explicitly for automated optical inspection (AOI) of solder fillets. This eliminates reliance on X-ray for process validation and improves first-pass yield in high-volume SMT lines.
What is the typical transition frequency (fT) of the internal transistor?
The built-in PNP transistor has fT = 180 MHz at VCE = −5 V, IC = −10 mA, and f = 100 MHz. This bandwidth supports fast digital switching (tON/tOFF < 50 ns) but is not intended for RF amplification; the RET is optimized for DC and low-frequency (<1 MHz) switching.
