Product details
Overview
PDTC123JM from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT883 (DFN1006-3) package, featuring integrated 2.2 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2), rated for 50 V VCEO and 100 mA output current, used as a digital switch for IC input control and load switching in industrial and automotive signal interface circuits.
For engineers reviewing the PDTC123JM datasheet, PDTC123JM pinout, PDTC123JM application, or PDTC123JM equivalent, this part serves as a drop-in replacement for BC847-based digital switching stages where built-in biasing reduces PCB area, eliminates discrete resistor placement, and supports reflow-only assembly on FR4 with 0.35 mm pitch.
Technical Context
This RET integrates a monolithic NPN transistor with two precision laser-trimmed thin-film resistors-R1 connected between base and input, R2 between base and emitter-enabling single-pin drive operation without external bias network. It operates as a saturated switch with guaranteed VCE(sat) ≤ 100 mV at IC = 5 mA / IB = 0.25 mA.
The device exhibits DC current gain (hFE) ≥ 100 at VCE = 5 V and IC = 10 mA, transition frequency fT = 230 MHz (typ.), and thermal resistance Rth(j-a) = 500 K/W on standard FR4, supporting operation from −65 °C to +150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; defines safe switching range for 24 V industrial logic interfaces. |
| IO | 100 mA - Continuous output current rating; supports driving LED indicators, small relays, or logic inputs without derating at Tamb ≤ 25 °C. |
| R1 | 2.2 kΩ (1.54–2.86 kΩ) - Input bias resistor; sets base current for predictable turn-on with 3.3 V/5 V MCU GPIOs. |
| R2/R1 ratio | 21 (17–26) - Feedback-to-input resistor ratio; ensures stable saturation and prevents thermal runaway under varying temperature. |
| VCE(sat) | ≤100 mV at IC=5 mA/IB=0.25 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| hFE | ≥100 at VCE=5 V, IC=10 mA - Sufficient current gain to maintain forced β ≥ 20 in typical digital switch configurations. |
| fT | 230 MHz - Transition frequency of internal transistor; confirms suitability for <10 MHz digital signal switching with clean edges. |
Pinout & Package
PDTC123JM is housed in a leadless ultra-small DFN1006-3 (SOT883) package measuring 1.02 × 0.60 × 0.48 mm, optimized for high-density PCB layouts and automated reflow assembly only. The package has no exposed pad and requires precise stencil-defined solder paste deposition per Nexperia's footprint spec (0.35 mm pitch, 0.4 mm solder land width).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base node) | Driven directly by MCU GPIO or logic signal; connects internally to R1 and transistor base. |
| 2 | Ground (emitter node) | Common reference terminal; ties internally to emitter and R2; must be connected to system GND plane. |
| 3 | Output (collector node) | Switched high-side output; connects to load (e.g., LED anode or IC input pull-up); sinks current when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | Eliminates 2 external resistors, reducing BOM count and layout area by ~1.2 mm² vs. discrete BC847 + bias solution. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, HAST, and ESD (HBM ≥ 8 kV), enabling use in under-hood ECUs and body controllers. |
| SOT883 ultra-small footprint | 0.35 mm pitch and 1.02 × 0.60 mm body allows placement in space-constrained modules such as sensor nodes and wearable electronics. |
| Guaranteed VI(on)/VI(off) | VI(on) ≤ 0.75 V (typ.) and VI(off) ≥ 0.6 V (typ.) ensure robust noise margin against 3.3 V CMOS logic thresholds. |
Applications
| Industrial Digital Control | Automotive Body Electronics |
|---|---|
|
Use Scenario: Driving optocoupler inputs in PLC I/O modules using 3.3 V microcontroller outputs. IC Role / Device Role / Timing Role: Level-shifting digital switch that converts low-current MCU GPIO into a 10–20 mA sink for opto-LED anodes. Use Value: Built-in R1/R2 ensures consistent turn-on without resistor tolerance stacking, improving batch-to-batch timing repeatability in 10 kHz polling loops. |
Use Scenario: Enabling/disabling CAN transceiver standby mode via microcontroller GPIO in door module ECUs. IC Role / Device Role / Timing Role: High-side enable switch controlling VCC supply to transceiver sleep circuitry. Use Value: AEC-Q101 qualification and 150 °C Tj rating allow direct integration near hot microcontrollers without thermal derating. |
| Cost-Sensitive Consumer IoT | Board-Level Signal Conditioning |
|
Use Scenario: Replacing BC847 + two 0402 resistors in smart home sensor hubs to reduce component count and assembly cost. IC Role / Device Role / Timing Role: Digital buffer isolating MCU pins from capacitive loads (e.g., long traces to status LEDs). Use Value: Eliminates pick-and-place steps for two passive components, cutting SMT line cycle time by ~0.8 seconds per unit at volume production. |
Use Scenario: Providing clean, rail-to-rail logic-level translation between 5 V legacy peripherals and 3.3 V microcontrollers. IC Role / Device Role / Timing Role: Active pull-down switch ensuring fast, controlled discharge of floating bus lines during state transitions. Use Value: Low VCE(sat) (<100 mV) and fast turn-off (toff < 100 ns) prevent bus contention glitches in SPI/I²C shared-bus topologies. |
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 |
|---|---|---|---|
| PDTC114YM,315 | R1 = 10 kΩ, R2 = 47 kΩ → higher input impedance, lower IB, slower turn-on (ton ≈ 2× longer) | Better suited for 5 V logic with weak drive strength; less suitable for 3.3 V GPIO with limited sink capability | Select when interfacing with open-drain 5 V outputs or where reduced base current minimizes MCU loading. |
| BC847B,215 | No integrated resistors; requires external RB and RBE; hFE = 200–450 (wider spread); not AEC-Q101 qualified | Higher gain variability and no automotive qualification limit use to non-safety-critical commercial designs | Choose only for cost-sensitive non-automotive prototypes where manual resistor tuning is acceptable. |
Compared with PDTC123JM, PDTC114YM offers higher input impedance but slower switching, while BC847B delivers higher hFE at the cost of BOM complexity and no automotive reliability assurance-making PDTC123JM optimal for production-ready 3.3 V industrial and automotive digital interface designs.

FAQ
Is PDTC123JM compatible with lead-free reflow soldering?
Yes. PDTC123JM is qualified for lead-free reflow only, per JEDEC J-STD-020. Its SOT883 package requires peak temperatures up to 260 °C with ≤60 sec above 217 °C. Hand soldering or wave soldering is not recommended due to thermal stress on the ultra-thin die attach and bond wires.
What is the maximum allowable input voltage at Pin 1?
The absolute maximum input voltage at Pin 1 (I) is +12 V, and the minimum is −5 V, per the limiting values table. Exceeding these risks permanent damage to the integrated R1 resistor or base-emitter junction, especially under reverse bias conditions.
Can PDTC123JM drive a 10 mA LED directly from a 3.3 V GPIO?
Yes. With R1 = 2.2 kΩ, a 3.3 V input yields ~1.2 mA base current (after accounting for VI(on) ≈ 0.75 V), sufficient to saturate the transistor and deliver >10 mA collector current at VCE(sat) < 100 mV-verified across −40 °C to +125 °C operating range.
Does PDTC123JM require a heatsink in 100 mA continuous operation?
No. At 100 mA and VCE(sat) ≤ 100 mV, power dissipation is ≤10 mW. With Rth(j-a) = 500 K/W, junction temperature rise is <5 °C above ambient-well within the 150 °C Tj limit even at 125 °C ambient, eliminating need for thermal relief structures.
