Product details
Overview
PDTC123JE from NXP Semiconductors is an NPN resistor-equipped transistor (RET) in SOT416 (SC-75) package, designed for digital switching applications with built-in bias resistors R1 = 2.2 kΩ and R2/R1 = 21 (typ), 50 V VCEO, 100 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTC123JE datasheet, PDTC123JE pinout, PDTC123JE application, or PDTC123JE equivalent, this page delivers verified electrical parameters, thermal derating behavior, input/output voltage thresholds, and direct alternatives for IC input control and load switching in space-constrained automotive and industrial PCBs.
Technical Context
The PDTC123JE integrates a monolithic NPN transistor with two precision on-die bias resistors-R1 (2.2 kΩ, input) and R2 (47 kΩ, base-emitter feedback)-enabling single-resistor drive logic-level interfacing without external components. Its internal topology eliminates discrete base resistors while maintaining predictable VI(on)/VI(off) thresholds.
It operates as a saturated switch with VCE(sat) ≤ 100 mV at IC = 5 mA / IB = 0.25 mA, supports ±5 V to +12 V input voltage range, and delivers stable hFE ≥ 100 at IC = 10 mA, making it suitable for low-power digital signal conditioning and level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V maximum - enables safe operation in 24 V automotive supply rails with margin against transients. |
| IO | 100 mA continuous output - sufficient to drive LED indicators, small relays, or logic inputs without external amplification. |
| R1 | 2.2 kΩ (1.54–2.86 kΩ) - sets input current sensitivity for TTL/CMOS-compatible drive with ~2.3 mA at 5 V. |
| R2/R1 | 21 (17–26) - ensures stable saturation and prevents unintended turn-on due to leakage or noise. |
| VI(on) | 0.75 V (min) at IC = 5 mA - guarantees reliable turn-on with standard logic high outputs. |
| VI(off) | 0.6 V (typ) at IC = 100 µA - provides noise immunity against sub-threshold signals in noisy environments. |
| fT | 230 MHz - supports fast switching up to ~10–20 MHz square-wave operation in timing-critical digital interfaces. |
Pinout & Package
SOT416 (SC-75) ultra-small surface-mount package: 1.8 mm × 0.95 mm × 0.7 mm body, 3-pin leaded configuration with gull-wing leads, optimized for high-density routing and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level drive voltage; requires no external pull-up/down. |
| 2 | GND (emitter) | Common reference node; ties emitter directly to ground plane; forms return path for both R1 and R2 currents. |
| 3 | output (collector) | Switched output node; connects to load (e.g., LED anode or relay coil); sinks current when active. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors R1/R2 | Eliminates two external components per switch, reducing BOM count and PCB area in multi-channel driver designs. |
| AEC-Q101 qualification | Validated for automotive under-hood and infotainment applications with extended temperature (-65 °C to +150 °C) and reliability stress testing. |
| VCE(sat) ≤ 100 mV | Minimizes power loss (< 0.5 mW at 5 mA) and self-heating in battery-powered or thermally constrained modules. |
| Input voltage range: −5 V to +12 V | Supports bidirectional signal clamping and robust interface with mixed-voltage systems including 3.3 V, 5 V, and 12 V domains. |
| Thermal resistance Rth(j-a) = 830 K/W | Enables 150 mW power dissipation at ambient ≤ 25 °C; derates linearly to zero at ~107 °C on FR4 board. |
Applications
| Automotive LED Indicator Control | Industrial Digital Input Conditioning |
|---|---|
Use Scenario: Driving status LEDs on dashboard clusters or body control modules using 5 V MCU GPIOs. IC Role / Device Role / Timing Role: NPN switch that translates logic-high signal into collector-sinking current path for LED cathode connection.

IC Role / Device Role / Timing Role: Low-quiescent-load power gate that disconnects sensor VDD rail when inactive. Use Value: 100 nA ICBO and 1 µA ICEO minimize standby current, extending coin-cell life beyond 5 years in always-on monitoring applications. |
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 |
|---|---|---|---|
| PDTA123JE | PNP complement with identical R1/R2 values and SOT416 package; VECO = 50 V, IO = −100 mA. | Used where high-side switching or inverted logic polarity is required (e.g., active-low enable lines). | Select PDTA123JE when sourcing current from supply rail instead of sinking to ground. |
| BC847B,115 | Standard NPN BJT (no built-in resistors); hFE = 200–450; requires external base resistor network. | Offers higher gain and lower VCE(sat) but increases component count and layout complexity. | Choose BC847B,115 only if precise gain control or sub-50 mV saturation is mandatory and board space permits extra passives. |
Compared with PDTA123JE, PDTC123JE provides complementary NPN functionality with identical footprint and biasing; versus BC847B,115, it trades off minor VCE(sat) increase for significant BOM reduction and simplified layout in high-channel-count digital I/O designs.

FAQ
What is the maximum operating temperature for PDTC123JE?
The PDTC123JE has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance Rth(j-a) is 830 K/W on FR4 PCB, meaning power dissipation must be limited to 150 mW at 25 °C ambient, derating linearly to zero at approximately 107 °C ambient. This makes PDTC123JE suitable for under-hood automotive locations with proper thermal design.
Does PDTC123JE require external base resistors?
No, PDTC123JE does not require external base resistors. It integrates R1 = 2.2 kΩ (input resistor) and R2 = 47 kΩ (base-emitter feedback resistor) internally. These built-in resistors enable direct connection to logic outputs (e.g., 3.3 V or 5 V GPIOs) without additional components, simplifying circuit design and reducing PCB area-confirmed in Table 1 and Section 1.2 of the NXP datasheet.
Is PDTC123JE pin-compatible with other packages in the PDTC123J series?
No, PDTC123JE (SOT416) is not pin-compatible with PDTC123JM (SOT883), PDTC123JT (SOT23), or PDTC123JU (SOT323), despite sharing identical pin functions (1 = input, 2 = GND, 3 = output). Their physical footprints differ significantly: SOT416 has 0.95 mm width and gull-wing leads, while SOT883 is leadless and SOT23/SOT323 have larger dimensions and different land patterns. Board redesign is required for package substitution.
What is the typical transition frequency (fT) of PDTC123JE?
The typical transition frequency (fT) of PDTC123JE is 230 MHz, measured at VCE = 5 V and IC = 10 mA. This high fT supports fast digital switching with rise/fall times under 10 ns in properly terminated circuits, making PDTC123JE suitable for clock buffering, pulse shaping, and high-speed logic interface applications where bandwidth exceeds 20 MHz.
Can PDTC123JE be used in wave soldering processes?
No, PDTC123JE is qualified for reflow soldering only, as explicitly stated in Section 11 and Table 6 of the NXP datasheet. Wave soldering is not recommended due to thermal stress risks on the SOT416 package and potential damage to internal resistor elements. The manufacturer provides dedicated reflow footprints (Figure 16) and specifies reflow profile requirements-using wave soldering voids warranty and may cause parametric shift or failure.
