Product details
Overview
PDTC123ET from NXP Semiconductors is an NPN resistor-equipped transistor (RET) with integrated 2.2 kΩ base-emitter and base-collector bias resistors, designed for simplified digital switching in low-voltage logic interface circuits. It delivers 100 mA DC output current, supports 50 V collector-emitter breakdown voltage, and operates reliably across −65 °C to +150 °C ambient temperature - commonly used in microcontroller GPIO driver stages and LED load control.
For engineers reviewing the PDTC123ET datasheet, PDTC123ET pinout, PDTC123ET application, or PDTC123ET equivalent, key selection criteria include its SOT23 package footprint, built-in resistor ratio (R1/R2 = 1), guaranteed VCE(sat) ≤ 150 mV at IC = 10 mA/IB = 0.5 mA, and compatibility with reflow-only soldering per JEDEC J-STD-020.
Technical Context
This RET integrates two precision-matched 2.2 kΩ resistors (R1 = base-collector, R2 = base-emitter) to eliminate external bias components and ensure stable turn-on/turn-off behavior under varying supply conditions. Its hFE ≥ 30 at IC = 20 mA enables robust current gain without discrete base drive tuning.
The device functions as a single-transistor logic-level switch with defined input thresholds: Vi(on) = 1.6–2.0 V and Vi(off) = 0.5–1.2 V at specified IC, making it suitable for direct interfacing with 3.3 V and 5 V CMOS/TTL outputs without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum safe collector-emitter voltage before breakdown in open-base configuration |
| IO (DC) | 100 mA - continuous output current capability without thermal derating at Tamb ≤ 25 °C |
| R1 / R2 | 2.2 kΩ each - matched internal bias resistors enabling fixed-current drive and eliminating external components |
| VCE(sat) | ≤150 mV at IC = 10 mA, IB = 0.5 mA - ensures low conduction loss and minimal power dissipation in switching mode |
| Ptot | 250 mW at Tamb ≤ 25 °C (SOT23) - defines maximum steady-state power handling before thermal shutdown or degradation |
| hFE | ≥30 at VCE = 5 V, IC = 20 mA - guarantees minimum current amplification for reliable saturation under standard logic drive |
Pinout & Package
PDTC123ET uses the SOT23 (TO-236AB) plastic surface-mounted package: 3-lead, 1.1 mm × 0.9 mm × 1.3 mm body, optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Input node connected to internal R1 and R2 network | Accepts logic-level input; internal resistors set base current automatically - no external bias required |
| 2 (Collector) | Output current sink terminal | Connected to load (e.g., LED anode or relay coil); carries full switched current up to 100 mA |
| 3 (Emitter) | Reference and return path | Internally tied to ground reference; provides common emitter node for NPN operation and current return |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors (R1 = R2 = 2.2 kΩ) | Eliminates need for two external resistors, reducing BOM count and layout area by ~3 components per channel |
| Matched resistor ratio (R1/R2 = 1.0 ± 0.2) | Ensures consistent turn-on threshold and predictable saturation behavior across production lots |
| Vi(on) = 1.6–2.0 V at IC = 20 mA | Directly compatible with 3.3 V LVTTL and 5 V CMOS logic families without series resistor or level translation |
| Reflow-solder only (JEDEC J-STD-020 compliant) | Guarantees mechanical and electrical reliability when processed via standard lead-free reflow profiles |
Applications
| Microcontroller GPIO Driver | LED Indicator Control |
|---|---|
Use Scenario: Driving discrete LEDs from MCU I/O pins with limited current sourcing/sinking capability. IC Role / Device Role: NPN switch that inverts and amplifies logic signals to sink up to 100 mA per channel.

Use Scenario: Converting active-high control signals to active-low outputs for legacy peripherals. IC Role / Device Role: Single-transistor inverter stage with defined input hysteresis and rail-to-rail swing.

Use Scenario: Enabling/disabling low-current analog sensors or communication modules in battery-powered devices. IC Role / Device Role: Low-leakage (ICEO ≤ 1 μA) power switch controlled by system MCU. Use Value: Achieves <1 μA off-state current and fast turn-on (<100 ns propagation delay implied by Cc = 2.5 pF), extending battery life. |
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 |
|---|---|---|---|
| NSBC114EPDXV6T1G (onsemi) | R1 = 10 kΩ, R2 = 10 kΩ; higher input impedance; hFE min = 35 | Better suited for high-impedance microcontroller inputs; slightly slower switching due to larger R values | Select when lower base current draw is critical and Vi(on) > 2.0 V is acceptable |
| DTC123EKT146 (ROHM) | Same R1/R2 = 2.2 kΩ, but SOT-323 package; Ptot = 200 mW; Rth(j-a) = 625 K/W | Smaller footprint but lower power handling and higher thermal resistance than SOT23 | Select only for ultra-compact layouts where 250 mW rating is not required and thermal margin allows |
Compared with NSBC114EPDXV6T1G and DTC123EKT146, PDTC123ET offers optimal balance of low VCE(sat), industry-standard SOT23 compatibility, and proven thermal performance (Rth(j-a) = 500 K/W), making it preferred for general-purpose 3.3 V/5 V digital switching where board space and manufacturability are prioritized.

FAQ
Is PDTC123ET pin-compatible with other SOT23-based NPN transistors?
No - PDTC123ET has a unique internal resistor network connecting pins 1 (base), 2 (collector), and 3 (emitter). While the SOT23 physical outline matches standard 3-lead packages, its pin function differs from bare transistors like BC847 or MMBT3904, which lack integrated bias resistors and require external base drive.
What is the maximum operating frequency for PDTC123ET in switching applications?
PDTC123ET is characterized with Cc = 2.5 pF at VCB = 10 V, implying usable switching up to ~10 MHz in low-load configurations. However, datasheet does not specify fT or switching time parameters; for >1 MHz operation, verify turn-on/turn-off delays experimentally with actual load and drive conditions.
Can PDTC123ET be used in linear amplifier mode?
No - PDTC123ET is optimized for saturated switching, not linear amplification. Its built-in resistors fix the base bias point, preventing adjustable Q-point setting. Use discrete transistors like BC847 or PZT3904 for analog gain stages requiring variable bias and hFE-dependent operation.
Does PDTC123ET support lead-free reflow soldering?
Yes - the datasheet explicitly states "reflow soldering is the only recommended soldering method" and complies with JEDEC J-STD-020 moisture sensitivity level (MSL) requirements. It is qualified for standard Pb-free reflow profiles with peak temperatures up to 260 °C.
