Product details
Overview
PDTC123EMB from Nexperia is an NPN resistor-equipped transistor (RET) in a leadless DFN1006B-3 (SOT883B) package, designed as a single-chip digital switch with integrated 2.2 kΩ input and feedback bias resistors. It delivers 100 mA output current, supports 50 V collector-emitter voltage, and is AEC-Q101 qualified for automotive use - commonly deployed in low-current peripheral driver circuits and IC input control stages.
For engineers reviewing the PDTC123EMB datasheet, PDTC123EMB pinout, PDTC123EMB application, or PDTC123EMB equivalent, key selection considerations include its built-in resistor ratio (R2/R1 = 1.0 ±0.2), ultra-low profile (0.37 mm height), thermal resistance (500 K/W), and suitability for space-constrained mobile and automotive signal-switching designs.
Technical Context
This RET integrates an NPN bipolar transistor with two monolithically embedded thin-film resistors: R1 (2.2 kΩ) connected between base and input, and R2 (2.2 kΩ) between base and emitter. The fixed 1:1 bias ratio enables predictable saturation behavior without external components.
It operates as a digital on/off switch with VI(on) = 1.6 V (typ) at IC = 20 mA and VI(off) = 1.2 V (typ), ensuring clean logic-level compatibility with 1.8 V–5 V microcontrollers. Its fT = 230 MHz (typ) and CC = 2.5 pF support fast switching in low-power digital interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage under open-base conditions; defines voltage headroom for 24 V automotive or 3.3/5 V logic interface applications. |
| IO | 100 mA - Continuous DC output current capability; sufficient to drive LEDs, small relays, or logic inputs without external current amplification. |
| R1 | 2.2 kΩ (±30%) - Input bias resistor enabling direct connection to MCU GPIO; eliminates need for discrete pull-up/base resistor. |
| R2/R1 | 1.0 (±0.2) - Fixed feedback-to-input resistor ratio ensuring stable turn-on threshold and consistent hFE effective gain across temperature. |
| Ptot | 250 mW at Tamb ≤25 °C - Power dissipation limit defining maximum continuous switching duty cycle in FR4 PCB environments. |
| fT | 230 MHz (typ) - Transition frequency confirming suitability for >1 MHz digital switching (e.g., PWM dimming, data enable gating). |
| Rth(j-a) | 500 K/W - Junction-to-ambient thermal resistance on standard FR4; informs derating above 25 °C ambient (e.g., 150 mW at 75 °C). |
Pinout & Package
Package: DFN1006B-3 (SOT883B), leadless ultra-small plastic package; dimensions 1.0 × 0.6 × 0.37 mm; 3 solder lands; bottom-side thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input (base node) | Direct connection point for logic-level control signal; internally tied to R1 top terminal. |
| 2 (G) | GND (emitter) | Emitter reference and return path; connects to system ground plane; serves as common node for R2 and transistor emitter. |
| 3 (O) | Output (collector) | Switched high-side output node; sinks current when active; connects to load (e.g., LED cathode, IC input pull-down). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 + R2 resistors eliminate 2 external components and reduce BOM count in digital switching nodes. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥8 kV), enabling use in body electronics modules. |
| Ultra-compact footprint | DFN1006B-3 (1.0 × 0.6 mm) saves >70% board area vs. SOT23, critical for wearable and ultra-thin mobile PCBs. |
| Low-profile packaging | 0.37 mm max height enables stacking under shields or integration into tight mechanical envelopes (e.g., camera modules). |
| Logic-compatible VI(on)/VI(off) | 1.6 V typical turn-on and 1.2 V typical turn-off thresholds ensure robust operation with 1.8 V and 3.3 V I/O standards. |
Applications
| Automotive Body Control Module | Smartphone Peripheral Interface |
|---|---|
Use Scenario: Driving LED status indicators and small solenoid valves in door module PCBs. IC Role / Device Role / Timing Role: Digital output switch replacing discrete BJT + two resistors; provides level-shifted, current-limited drive from 3.3 V MCU GPIO.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC114EMB | R1 = 10 kΩ, R2 = 10 kΩ - higher input impedance reduces MCU GPIO loading but increases VI(on) to 2.0 V (typ). | Better suited for 5 V logic systems; less optimal for 1.8 V/3.3 V MCUs due to higher turn-on threshold. | Select when interfacing with legacy 5 V controllers or where lower input current (<1 µA standby) is prioritized over speed. |
| PDTC143EMB | R1 = 4.7 kΩ, R2 = 4.7 kΩ - intermediate bias value yields VI(on) = 1.8 V (typ); fT = 180 MHz (typ), ~22% lower than PDTC123EMB. | Slightly slower switching; suitable for <500 kHz PWM or general-purpose logic buffering where 230 MHz is unnecessary. | Choose for cost-sensitive consumer applications where marginal speed reduction is acceptable for broader supply-chain availability. |
Compared with PDTC114EMB and PDTC143EMB, PDTC123EMB offers the lowest VI(on) and highest fT among Nexperia's 100 mA RET family, making it optimal for high-speed, low-voltage digital switching in space-constrained automotive and portable designs.

FAQ
What is the maximum allowable junction temperature for PDTC123EMB?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in the limiting values table. Operation beyond this temperature risks permanent degradation of the silicon die and embedded resistors. Derating begins at 25 °C ambient, with total power dissipation linearly reduced to zero at 150 °C ambient per the published power derating curve.
Can PDTC123EMB be used in reverse-biased configurations (e.g., emitter-follower mode)?
No - PDTC123EMB is optimized as a grounded-emitter NPN switch. Its internal R1–R2 network assumes emitter (Pin 2) as the reference node. Using it in emitter-follower or inverted configurations disrupts biasing, invalidates VI(on)/VI(off) specifications, and may cause unpredictable conduction or thermal overstress due to uncontrolled base current paths.
Is reflow soldering the only recommended assembly method?
Yes - the datasheet explicitly states that reflow soldering is the only recommended method. Hand soldering or wave soldering is not qualified and risks damage due to the DFN1006B-3 package's thermal sensitivity and small land geometry. Reflow profiles must follow JEDEC J-STD-020, with peak temperature ≤260 °C and time above liquidus ≤60 seconds.
How does the R2/R1 ratio tolerance affect switching performance?
The R2/R1 ratio tolerance of ±0.2 directly impacts the effective base current and thus the guaranteed saturation margin. At R2/R1 = 0.8, hFE effective drops, increasing VCE(sat); at 1.2, excess base drive may raise power loss. Designers should verify worst-case VCE(sat) (≤150 mV typ, ≤250 mV max) and switching speed using the min/max R1 (1.54 kΩ / 2.86 kΩ) in SPICE simulations.
