Product details
Overview
PDTA144EQB-Q from Nexperia is a 50 V, 100 mA PNP resistor-equipped transistor (RET) in a DFN1110D-3 (SOT8015) leadless package with side-wettable flanks. It integrates 47 kΩ input and output bias resistors, delivers −100 mA output current, exhibits −1.2 V to −0.8 V off-state input voltage, and is AEC-Q101 qualified for automotive load switching applications.
For engineers reviewing the PDTA144EQB-Q datasheet, PDTA144EQB-Q pinout, PDTA144EQB-Q application, or PDTA144EQB-Q equivalent, this device serves as a space-optimized, AOI-compatible digital switch with built-in biasing for IC input control and low-power load management in constrained PCB layouts.
Technical Context
This PNP RET integrates two precision silicon resistors (R1 = R2 = 47 kΩ) directly into the die assembly, eliminating external base resistors and reducing component count. Its internal transistor features a minimum DC current gain (hFE) of 80 at −5 mA collector current and −5 V VCE, with collector-emitter saturation voltage ≤ −100 mV under −10 mA/−0.5 mA drive conditions.
The device operates across −55 °C to +150 °C ambient temperature, supports automatic optical inspection via side-wettable flanks, and meets AEC-Q101 stress qualification for automotive under-hood and body-control modules requiring robust, miniaturized discrete switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive systems with margin. |
| IO | −100 mA: Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 / R2 | 47 kΩ / 47 kΩ: Matched on-die bias resistors; eliminates external components and ensures consistent turn-on/off thresholds. |
| VI(off) | −1.2 V to −0.8 V: Input voltage range guaranteeing reliable cutoff; prevents false triggering in noisy environments. |
| VCE(sat) | ≤ −100 mV at IC = −10 mA, IB = −0.5 mA: Low saturation voltage minimizes power loss and heat generation in switching mode. |
| hFE | 80 min at VCE = −5 V, IC = −5 mA: Sufficient current gain for predictable digital switching without overdesigning drive circuitry. |
| Package | DFN1110D-3 (SOT8015): 1.1 × 1.0 × 0.48 mm ultra-thin leadless package with side-wettable flanks for solder-joint AOI verification. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Internal connection to R1; accepts logic-level control signal to enable PNP conduction path. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; forms common reference for input and output paths. |
| 3 | Output (collector) | Switched high-side output node; sinks current from load connected between VCC and pin 3. |
Key Features

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 |
|---|---|---|---|
| PDTC144EQB-Q | NPN complement with identical R1/R2 (47 kΩ), same package and AEC-Q101 rating, but opposite polarity switching. | Requires inverted logic drive and low-side load configuration instead of high-side PNP topology. | Select when load must be grounded and switched on the low side, or when existing NPN-based board layout reuse is prioritized. |
| BC857B-Q | Discrete PNP transistor without integrated resistors; requires external 47 kΩ base resistor and occupies larger footprint (SOT23). | Offers higher hFE (≥200) but increases component count, layout complexity, and AOI inspection burden. | Choose only if precise gain tuning or higher current gain is required, and board space and assembly cost are secondary concerns. |
Compared with PDTC144EQB-Q, PDTA144EQB-Q enables high-side switching with native logic compatibility; compared with BC857B-Q, it reduces bill-of-materials count and improves manufacturability while maintaining automotive-grade reliability in a 40% smaller footprint.

FAQ
What is the maximum continuous collector current for PDTA144EQB-Q?
The maximum continuous output current is −100 mA at Tamb ≤ 25 °C on a standard FR4 PCB with 35 µm copper. Derating applies above 25 °C per Figure 1; at 100 °C ambient, maximum usable current drops to approximately −65 mA to maintain junction temperature below 150 °C.
Can PDTA144EQB-Q replace BC857B-Q without circuit modification?
No - PDTA144EQB-Q integrates 47 kΩ base and emitter resistors, whereas BC857B-Q is a bare transistor requiring external biasing. Direct replacement would cause incorrect biasing and likely failure. A redesign removing the external resistor and verifying VI(on)/VI(off) compatibility is required.
Is the DFN1110D-3 package compatible with standard reflow profiles?
Yes - the DFN1110D-3 package is qualified for JEDEC J-STD-020-compliant reflow. Recommended stencil thickness is 0.1 mm, and solder paste volume must match the footprint in Figure 31 to ensure reliable side-wettable flank formation and void-free joints.
Does PDTA144EQB-Q support bidirectional signal routing?
No - it is a unidirectional PNP switch optimized for high-side current sinking. The internal structure lacks symmetrical terminals or reverse-biased operational ratings; using it for reverse current or AC signal switching violates absolute maximum ratings and risks permanent damage.
