Product details
Overview
PDTA123JQB-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 2.2 kΩ input and 47 kΩ base-emitter bias resistors, delivers hFE = 100 at IC = −5 mA / VCE = −5 V, and achieves VCE(sat) ≤ −100 mV - used for digital load switching and IC input control in space-constrained automotive and industrial PCBs.
For engineers reviewing the PDTA123JQB-Q datasheet, PDTA123JQB-Q pinout, PDTA123JQB-Q application, or PDTA123JQB-Q equivalent, this part serves as an AEC-Q101-qualified, ultra-thin (0.48 mm height) PNP RET optimized for AOI-compatible assembly, low-component-count digital interface circuits, and cost-sensitive 5 V/3.3 V logic-level switching.
Technical Context
This PNP RET embeds two monolithic silicon resistors to form a single-input, single-output active switch with fixed bias network. Its internal topology eliminates external base resistors while maintaining predictable turn-on/off thresholds across temperature (−55 °C to +150 °C).
The device operates with verified off-state input voltage VI(off) = −0.6 V to −0.5 V and on-state input voltage VI(on) = −1.1 V to −0.75 V under defined IC conditions, enabling reliable interfacing with standard CMOS/TTL outputs without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - supports robust operation in 24 V automotive supply rails with margin |
| IO | −100 mA - drives moderate loads such as LEDs, relays, or gate inputs directly |
| R1 / R2 | 2.2 kΩ / 47 kΩ - sets precise base current for consistent saturation at logic-compatible input levels |
| hFE | 100 (min) at −5 mA / −5 V - ensures stable gain for predictable switching behavior |
| VCE(sat) | ≤ −100 mV - minimizes conduction loss and self-heating in high-duty-cycle applications |
| Tj max | +150 °C - qualified per AEC-Q101 for under-hood and powertrain environments |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, leadless, ultra-thin (0.48 mm body height) plastic package with side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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 |
|---|---|---|---|
| PDTC123JQB-Q | NPN complement; identical R1/R2 values and package; requires inverted logic drive | Suitable where load is connected to VCC (high-side switching), not ground-referenced | Select when driving common-anode LEDs or sourcing current into pull-up networks |
| BC857B-Q | Discrete PNP transistor without integrated resistors; requires external base bias network | Offers higher hFE (200–450) but increases component count and layout complexity | Choose only when variable gain or adjustable switching threshold is required |
Compared with PDTC123JQB-Q, PDTA123JQB-Q provides native low-side sinking with direct logic compatibility; versus BC857B-Q, it trades minor hFE reduction for 2-resistor elimination, AOI support, and AEC-Q101 assurance - critical for production scalability and automotive compliance.

FAQ
What is the maximum continuous collector current for PDTA123JQB-Q?
The absolute maximum continuous collector 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 75 °C ambient, maximum sustainable current drops to approximately −65 mA to maintain junction temperature below 150 °C.
Does PDTA123JQB-Q require external base resistors?
No. It integrates a 2.2 kΩ input resistor (R1) and a 47 kΩ base-emitter resistor (R2), forming a complete bias network. This eliminates the need for external resistors in standard digital switching configurations, reducing bill-of-materials count and PCB real estate.
Is PDTA123JQB-Q suitable for automotive applications?
Yes. It is fully qualified to AEC-Q101 standards for stress testing of discrete semiconductors and explicitly recommended for automotive use. Its construction, thermal performance, and reliability data meet requirements for body electronics, infotainment, and power distribution modules.
What is the marking code for PDTA123JQB-Q on the package?
The top-side marking is "D2", as specified in Table 5 of the datasheet. This 2-character laser mark appears on the transparent top view of the DFN1110D-3 package and is used for traceability and automated optical recognition during assembly.
