Product details
Overview
PDTB123EQAZ from Nexperia is a PNP resistor-equipped transistor (RET) in a DFN1010D-3 (SOT1215) package, designed for digital switching and IC input control. It features 2.2 kΩ integrated base bias resistors (R1 = R2), −50 V VCEO, −500 mA IO rating, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTB123EQAZ datasheet, PDTB123EQAZ pinout, PDTB123EQAZ application, or PDTB123EQAZ equivalent, this device serves as a space-optimized, solder-joint-inspectable alternative to discrete BC807/BC817-based switch circuits in low-voltage logic interface and load control designs.
Technical Context
This RET integrates matched 2.2 kΩ input and feedback resistors to enable single-pin base drive with predictable turn-on/off thresholds. Its dual-collector configuration (pins 3 and 4) supports higher current handling and thermal spreading on PCBs.
The device operates with VI(on) = −1.0 to −2.0 V at IC = −20 mA and VI(off) = −0.6 to −1.8 V at IC = −100 µA, ensuring robust noise margin in 3.3 V and 5 V digital systems. Its fT = 150 MHz and hFE = 40 (typ.) at IC = −50 mA confirm suitability for medium-speed switching up to ~10 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Withstands reverse collector-emitter voltage in automotive and industrial power-rail switching. |
| IO | −500 mA - Supports direct driving of moderate-current loads like LEDs, relays, or gate inputs without external amplification. |
| R1 / R2 | 2.2 kΩ each - Enables clean logic-level switching with no external bias components; ±10% ratio tolerance ensures consistent gain stability. |
| VCEsat | −100 mV max at IC = −50 mA / IB = −2.5 mA - Minimizes conduction loss and self-heating in high-duty-cycle applications. |
| fT | 150 MHz - Supports reliable switching at frequencies up to 10 MHz with controlled rise/fall times in digital interface circuits. |
| Package | DFN1010D-3 (SOT1215), 1.1 × 1.0 × 0.37 mm - Ultra-thin, leadless, AOI-compatible footprint for high-density portable and automotive PCBs. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive discrete semiconductors, enabling use in body electronics and infotainment modules. |
Pinout & Package
DFN1010D-3 (SOT1215) is a 4-terminal, leadless, thermally enhanced ultra-thin package with visible side pads for optical inspection and reliable reflow soldering. Body dimensions: 1.1 mm × 1.0 mm × 0.37 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Single-point connection for logic-level control signal; internal R1 connects here to emitter. |
| 2 | GND (emitter) | Common reference node; ties internal R2 and transistor emitter; must be connected to system ground plane. |
| 3 | O (collector) | Primary high-current output path; electrically identical to pin 4; used for standard load connection. |
| 4 | O (collector) | Duplicate collector terminal; improves current sharing and thermal dissipation when both pins are routed to copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Matched 2.2 kΩ R1/R2 eliminates external resistors, reducing BOM count and layout area by ≥2 components per switch node. |
| Low-profile packaging | 0.37 mm height enables use in ultra-thin consumer wearables and stacked automotive modules where Z-height is constrained. |
| AOI-solderable side pads | Visible copper sidewalls allow automated optical inspection of solder joint integrity-critical for zero-defect automotive manufacturing. |
| Dual-collector terminals | Pins 3 and 4 provide parallel current paths, lowering effective RDS(on)-equivalent resistance and improving thermal performance on FR4 PCBs. |
| Automotive qualification | AEC-Q101 compliance confirms reliability under temperature cycling, humidity, and mechanical shock conditions required for under-hood and cabin electronics. |
Applications
| LED Driver Interface | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving 20 mA indicator LEDs from 3.3 V MCU outputs in automotive instrument clusters. IC Role / Device Role / Timing Role: Level-shifting, current-sinking switch with defined VI(on)/VI(off) thresholds to prevent false triggering. Use Value: Eliminates need for two external resistors per LED, saving 0.5 mm² PCB area per channel and enabling 12-channel LED banks in <8 mm². |
Use Scenario: Extending limited GPIO count on ARM Cortex-M0+ MCUs to control multiple peripheral enable lines. IC Role / Device Role / Timing Role: Digital buffer with hFE = 40 and fT = 150 MHz, supporting clean 10 MHz toggle rates without signal degradation. Use Value: Reduces component count vs. discrete BJT + resistor solutions by 67%, accelerating layout and lowering assembly cost in high-volume IoT nodes. |
| Automotive Door Module Load Switch | Industrial Sensor Signal Conditioning |
Use Scenario: Controlling 100–300 mA window motor drivers or mirror fold actuators in door control units. IC Role / Device Role / Timing Role: High-side switch replacement in grounded-load configurations; handles repetitive 500 mA pulsed loads. Use Value: −500 mA IO rating and −50 V VCEO ensure safe operation during load dump transients; AEC-Q101 certification validates field reliability. |
Use Scenario: Isolating and conditioning analog sensor outputs (e.g., thermistor networks) before ADC input in PLC I/O modules. IC Role / Device Role / Timing Role: Active pull-down switch that disables sensor bias paths during sleep mode to reduce quiescent current. Use Value: VI(off) ≤ −1.8 V guarantees full cutoff at 0 V logic levels, cutting leakage to <0.5 µA and extending battery life in remote sensors. |
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 |
|---|---|---|---|
| PDTB123EQA | Same silicon, identical R1/R2 (2.2 kΩ), but unmarked DFN1010D-3 package without Z-suffix; no guaranteed traceability or extended temp screening. | Lacks Z-grade marking and may not meet full AEC-Q101 lot traceability requirements for Tier-1 automotive programs. | Select PDTB123EQAZ when full automotive documentation, lot traceability, and guaranteed −40 °C to +150 °C operation are contractually required. |
| PDTD123EQAZ | NPN complement with same R1/R2 values, package, and AEC-Q101 rating; polarity inverted; VI(on) positive, VCEsat referenced to emitter. | Used where active-high control or sourcing (vs. sinking) is needed-e.g., driving NMOS gates or high-side LED anodes. | Choose PDTD123EQAZ only when circuit topology requires NPN behavior; not a drop-in replacement due to polarity reversal. |
Compared with PDTB123EQA, the Z-suffix variant guarantees full automotive traceability and extended temperature validation; versus PDTD123EQAZ, it provides complementary PNP functionality essential for grounded-load switching where sourcing capability is unnecessary or undesirable.

FAQ
What is the function of pins 3 and 4 on PDTB123EQAZ?
Pins 3 and 4 are electrically identical collector terminals. Both connect internally to the same transistor collector node and are intended to be used in parallel-either individually or together-to improve current handling, reduce thermal resistance, and enhance solder joint reliability on PCBs. They are not separate devices or channels.
Can PDTB123EQAZ replace BC807-40 in existing designs?
Yes, with layout adaptation: PDTB123EQAZ provides equivalent PNP switching capability (−50 V, −500 mA) and higher hFE (40 vs. BC807-40's 250–630, but more consistent due to built-in bias). However, its DFN1010D-3 footprint differs from SOT23, requiring PCB redesign and verification of VI(on)/VI(off) compatibility with driving logic.
What does the 'Z' suffix signify in PDTB123EQAZ?
The 'Z' denotes Nexperia's automotive-grade variant: full AEC-Q101 qualification with documented lot traceability, extended temperature screening (−40 °C to +150 °C), and guaranteed compliance with automotive PPAP requirements-not just electrical equivalence but full process and reliability validation for Tier-1 supply chains.
How is thermal performance affected when using only pin 3 (not pin 4)?
Using only pin 3 increases thermal resistance by ~15–20% compared to connecting both pins 3 and 4 to a common copper pour. Data shows Rth(j-a) improves from 239 K/W (4-layer PCB, standard footprint) to 133 K/W when both collectors are utilized-critical for sustained 300+ mA operation above 70 °C ambient.
