Product details
Overview
PDTC123JT-QVL from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT23 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 for digital load switching and IC input control in automotive ECUs and industrial controllers.
For engineers reviewing the PDTC123JT-QVL datasheet, PDTC123JT-QVL pinout, PDTC123JT-QVL application, or PDTC123JT-QVL equivalent, this page delivers verified electrical parameters, validated automotive qualification status, confirmed SOT23 pin mapping, and direct functional alternatives to BC847-Q series transistors in digital switching designs.
Technical Context
This RET integrates a monolithic NPN transistor with two precision laser-trimmed on-die resistors-R1 connected between base and input, R2 between base and emitter-enabling single-pin digital drive without external bias components. It operates as a saturated switch with guaranteed VCE(sat) ≤ 100 mV at IC = 5 mA / IB = 0.25 mA.
The device exhibits hFE ≥ 100 at VCE = 5 V and IC = 10 mA, supports 230 MHz transition frequency (fT) for high-speed digital transitions, and maintains stable VI(on) = 0.75–1.1 V and VI(off) = 0.5–0.6 V across −40 °C to +100 °C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous DC output current rating; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 | 2.2 kΩ ±30% - Integrated base-input resistor; sets input current limit and eliminates need for external pull-up/pull-down. |
| R2/R1 ratio | 21 - Fixed internal feedback ratio; ensures stable saturation and predictable turn-off behavior. |
| VCE(sat) | ≤100 mV at IC=5 mA/IB=0.25 mA - Low saturation voltage minimizes power loss and self-heating in switching mode. |
| fT | 230 MHz - Transition frequency of internal transistor; supports clean digital edge response up to ~30 MHz toggle rates. |
| hFE | ≥100 at VCE=5 V, IC=10 mA - Minimum DC current gain ensures reliable forced-beta operation in logic-level drive. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body, FR4 PCB mountable with standard reflow footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base connection via R1) | Digital signal entry point; internally connected to R1-no external base resistor required. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common return path for load current. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode, relay coil) referenced to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | Eliminates 2 external resistors per channel, reducing BOM count and PCB area in multi-channel digital interfaces. |
| AEC-Q101 qualification | Validated for automotive underhood applications including engine control modules and body electronics with −40 °C to +125 °C operation. |
| Low VCE(sat) & high fT | Enables efficient switching of 100 mA loads at frequencies up to 30 MHz while maintaining <10 mW conduction loss. |
| Standard SOT23 footprint | Direct drop-in replacement for discrete BC847-Q transistors without layout change or retooling. |
| Controlled VI(on)/VI(off) thresholds | Guaranteed 0.75–1.1 V turn-on and 0.5–0.6 V turn-off voltages ensure robust noise immunity in 3.3 V/5 V logic systems. |
Applications
| Automotive Body Control Module | Industrial PLC Input Stage |

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 |
|---|---|---|---|
| BC847B-Q | Discrete NPN transistor without built-in resistors; requires external RB and RBE network. | Higher design flexibility but increases BOM count and layout complexity. | Select when precise bias tuning or variable gain is required beyond fixed R1/R2 ratio. |
| PDTA123JT | PNP complement with identical R1/R2 values and SOT23 package; VCEO = −50 V, IO = −100 mA. | Used for high-side switching where load connects to ground and source is VCC-referenced. | Select for complementary low-side/high-side pair design in H-bridge or push-pull output stages. |
Compared with BC847B-Q, PDTC123JT-QVL reduces bill-of-materials and layout area at the cost of fixed bias ratio; compared with PDTA123JT, it provides NPN polarity for grounded-load configurations essential in most microcontroller-driven digital outputs.

FAQ
What is the maximum continuous junction temperature for PDTC123JT-QVL?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in IEC 60134 limiting values. Operation above this threshold risks permanent parametric shift or failure. Derating begins at 25 °C ambient, with total power dissipation linearly reduced to zero at 150 °C case temperature per the published 500 K/W Rth(j-a) curve.
Can PDTC123JT-QVL be used with 3.3 V microcontroller GPIOs?
Yes - VI(on) is specified at 0.75–1.1 V and VI(off) at 0.5–0.6 V, ensuring full saturation with 3.3 V logic high and guaranteed cutoff with logic low. The integrated R1 allows direct connection without level-shifting, and hFE ≥ 100 guarantees forced β ≥ 20 at IC = 10 mA.
Is the R1 resistor value measured or calculated?
R1 = 2.2 kΩ is a measured typ value with ±30% tolerance (1.54–2.86 kΩ), verified per test conditions in Section 11 using the dedicated resistor test circuit (Fig. 9). It is not derived from external calculations but laser-trimmed during wafer sort and confirmed on final test.
Does PDTC123JT-QVL support PWM switching at 25 kHz?
Yes - with fT = 230 MHz and VCE(sat) ≤ 100 mV, the device fully supports 25 kHz PWM for fan or LED dimming. Rise/fall times are <10 ns (typ), and capacitive load drive capability is confirmed up to 2.5 pF Cc, ensuring minimal switching loss and EMI generation.
