Product details
Overview
PDTB123YQAZ from Nexperia is a PNP resistor-equipped transistor (RET) designed for digital switching and IC input control in space-constrained automotive and industrial applications. It features integrated 2.2 kΩ input bias resistor (R1), 10 kΩ pull-down resistor (R2), −50 V VCEO, −500 mA IO, and AEC-Q101 qualification for automotive reliability.
For engineers reviewing the PDTB123YQAZ datasheet, PDTB123YQAZ pinout, PDTB123YQAZ application, or PDTB123YQAZ equivalent, this device serves as a drop-in replacement for BC807/BC817 series in logic-level interfacing, load switching, and microcontroller GPIO buffering - with verified thermal performance on FR4 PCBs and AOI-compatible solder joints.
Technical Context
This RET integrates a PNP bipolar transistor with two monolithically embedded silicon resistors: R1 (2.2 kΩ) connects base to input, and R2 (10 kΩ) pulls base to emitter. The resulting R2/R1 ratio of 4.55 ±10% ensures stable saturation under varying drive conditions.
It operates with −5 V VEBO, −100 mV VCEsat at IC = −50 mA / IB = −2.5 mA, and delivers hFE ≥70 at VCE = −5 V, enabling robust digital switching without external bias components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown; supports 24 V automotive rail switching with margin. |
| IO | −500 mA: Continuous output current capability; sufficient for driving relays, LEDs, or small solenoids directly. |
| R1 | 2.2 kΩ ±30%: Input bias resistor enabling direct TTL/CMOS logic-level drive without external components. |
| R2/R1 | 4.55 ±10%: Precise internal resistor ratio ensuring reliable turn-off and noise immunity in noisy environments. |
| VCEsat | −100 mV @ IC = −50 mA: Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switching. |
| AEC-Q101 | Qualified: Meets stress test requirements for discrete semiconductors in automotive applications (temperature cycling, HTRB, etc.). |
| Package | DFN1010D-3 (SOT1215): 1.1 × 1.0 × 0.37 mm ultra-thin leadless package with side-wettable flanks for AOI and reflow compatibility. |
Pinout & Package
DFN1010D-3 (SOT1215) is a 3-terminal, leadless surface-mount package with visible side pads for automated optical inspection and enhanced thermal conduction. Body dimensions: 1.1 mm × 1.0 mm × 0.37 mm height; thermal resistance Rth(j-sp) = 40 K/W to solder point.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level voltage to enable transistor conduction. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference and current return path. |
| 3 & 4 | Output (collector) | Dual-collector terminals (pins 3 and 4) are internally shorted; provide parallel current paths and lower thermal resistance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates need for two external resistors, reducing BOM count and PCB area in digital interface circuits. |
| AEC-Q101 qualification | Validated for automotive under-hood and infotainment systems per stress test requirements including temperature cycling and HTRB. |
| 0.37 mm profile | Enables use in ultra-thin portable and wearable electronics where Z-height is constrained by mechanical stack-up. |
| Side-wettable flanks | Supports automated optical inspection (AOI) of solder joints, improving manufacturing yield and process traceability. |
| FR4 thermal performance | Delivers 940 mW Ptot on 4-layer FR4 with 1 cm² collector pad - 2.9× higher than standard footprint mounting. |

FAQ
What is the maximum continuous power dissipation for PDTB123YQAZ on a standard FR4 PCB?
On a single-sided FR4 PCB with standard footprint (no extended copper), PDTB123YQAZ has a Ptot rating of 325 mW at Tamb = 25 °C. With a 1 cm² collector pad, this increases to 575 mW due to improved thermal conduction - confirmed in Table 6 of the official datasheet.
Can PDTB123YQAZ be used as a direct replacement for BC807-40 in existing designs?
Yes - PDTB123YQAZ provides equivalent PNP functionality with integrated biasing, eliminating the need for two external resistors. Its −50 V VCEO, −500 mA IO, and −100 mV VCEsat meet or exceed BC807-40 specs, and its DFN1010D-3 footprint is compatible with reflow profiles used for SOT-23 packages.
Does PDTB123YQAZ support Automatic Optical Inspection (AOI) of solder joints?
Yes - the DFN1010D-3 package features side-wettable flanks that expose solder along the lateral edges of pins 1, 2, 3, and 4. This enables reliable AOI detection of solder fillet quality, a key requirement for automotive and industrial manufacturing lines.
What is the off-state input voltage (VI(off)) range for reliable turn-off behavior?
At VCE = −5 V and IC = −100 µA, VI(off) is specified from −0.4 V (min) to −1.0 V (max). This ensures robust turn-off even with small positive noise spikes on the input line, supporting reliable operation in electrically noisy automotive environments.
