Product details
Overview
PDTC123YT from Nexperia is an NPN resistor-equipped transistor (RET) in SOT23 package, featuring integrated bias resistors R1 = 2.2 kΩ and R2 = 10 kΩ, VCEO = 50 V, IO = 100 mA, and AEC-Q101 qualification. It functions as a single-chip switch/driver for digital interface circuits, eliminating external base resistors in microcontroller GPIO-driven loads.
For engineers reviewing the PDTC123YT datasheet, PDTC123YT pinout, PDTC123YT application, or PDTC123YT equivalent, key selection criteria include built-in R1/R2 ratio (4.5 typ), low VCEsat (150 mV @ 10 mA/0.5 mA), off-state input voltage (0.75 V typ), and automotive-grade reliability for space-constrained DC switching.
Technical Context
This RET integrates two precision thin-film resistors to configure fixed-current gain control: R1 connects base to input, R2 shunts base to emitter, enabling direct logic-level drive without external biasing. Its internal topology supports fast turn-on/turn-off with predictable saturation behavior across -40 °C to 125 °C.
The device operates as a saturated switch under standard TTL/CMOS logic drive, with VI(on) = 1.15 V (typ) at IC = 20 mA and VI(off) = 0.75 V (typ) at IC = 100 µA - ensuring robust noise immunity and clean digital transitions in mixed-signal interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V industrial control rails. |
| IO | 100 mA - Continuous output current rating; supports driving LEDs, small relays, or logic buffers directly. |
| R1 | 2.2 kΩ (typ) - Input bias resistor value; sets base current for defined switching threshold with 3.3 V/5 V logic. |
| R2/R1 | 4.5 (typ) - Internal resistor ratio; determines effective current gain and ensures stable saturation under varying temperature. |
| VCEsat | 150 mV (max @ IC = 10 mA, IB = 0.5 mA) - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| AEC-Q101 | Qualified - Meets automotive stress test requirements for discrete semiconductors; suitable for under-hood and ADAS subsystems. |
| Ptot | 250 mW (@ Tamb = 25 °C) - Total power dissipation limit on FR4 PCB; defines thermal derating envelope for layout planning. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pitch); thermally optimized for reflow soldering on standard FR4 PCBs with 35 µm copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input (base node) | Logic-level signal entry point connected internally to R1; accepts 3.3 V or 5 V CMOS/TTL drive without series resistor. |
| 2 (GND) | Ground (emitter node) | Emitter terminal tied to system ground; serves as common return path and reference for R2 bias network. |
| 3 (O) | Output (collector node) | Switched load connection point; sinks up to 100 mA when driven; requires external pull-up or load to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in R1 and R2 bias network | Eliminates two external resistors per switch channel, reducing BOM count and PCB area in multi-channel driver designs. |
| Fixed R2/R1 ratio of 4.5 (typ) | Ensures consistent hFE-equivalent gain across production lots and temperature, improving batch-to-batch predictability. |
| Low VI(on) of 1.15 V (typ) | Guarantees reliable turn-on with 1.8 V or higher logic families, including modern ultra-low-voltage MCUs and FPGAs. |
| AEC-Q101 qualification | Validated for automotive applications including body electronics, lighting control, and infotainment power management. |
| VCEsat ≤ 150 mV @ 10 mA | Reduces conduction losses by >60% vs. discrete BJT + resistor solutions, lowering thermal stress in dense layouts. |

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 |
|---|---|---|---|
| PDTC114YT | R1 = 10 kΩ, R2 = 10 kΩ (R2/R1 = 1.0), lower input sensitivity; hFE ≈ 160 (vs. 35–100 for PDTC123YT) | Better suited for high-impedance logic sources; less tolerant of leakage currents in battery-powered sleep modes | Select when driving from weak-sourcing outputs (e.g., older 74HC logic) or where higher gain stability is required. |
| MMBT3904LT1G | No integrated resistors; requires external RB; VCEO = 40 V; IC = 200 mA; not AEC-Q101 qualified | Higher current capability but adds design complexity and fails automotive qualification requirements | Choose only for non-automotive, cost-sensitive consumer applications where board space and qualification are secondary. |
Compared with PDTC123YT, PDTC114YT offers higher gain and lower input current demand but reduced noise margin, while MMBT3904LT1G provides greater current headroom at the expense of added components, thermal uncertainty, and no automotive compliance.

FAQ
What is the maximum continuous collector current for PDTC123YT?
The PDTC123YT is rated for 100 mA continuous output current (IO) under ambient conditions ≤25 °C with proper PCB thermal relief. Derating applies above 25 °C per the published power curve - at 75 °C ambient, usable current drops to ~65 mA to maintain junction temperature ≤150 °C.
Can PDTC123YT replace a standard BJT like BC847 in existing designs?
Yes, but only if the original design uses a base resistor and the required gain matches the PDTC123YT's effective hFE range (35–100). The RET's fixed R1/R2 ratio eliminates the base resistor but fixes biasing - verify VI(on)/VI(off) thresholds align with your driver's logic levels before substitution.
Is PDTC123YT compatible with lead-free reflow profiles?
Yes. PDTC123YT is qualified for standard IPC/JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C. The SOT23 package outline and recommended solder land patterns (Fig. 9) ensure reliable joint formation using typical 3-zone or 5-zone reflow ovens.
Does PDTC123YT support bidirectional signal routing?
No. PDTC123YT is a unidirectional NPN switch configured as a low-side sink. Its internal resistor network and pinout (I/GND/O) prevent reverse current flow or emitter-follower operation. For bidirectional or high-side switching, consider complementary PNP RETs like PDTA123YT or dedicated analog switches.
