Product details
Overview
PDTD123YT/APGVL from NXP Semiconductors is a 500 mA, 50 V NPN resistor-equipped transistor (RET) in SOT23 package with integrated bias resistors R1 = 2.2 kΩ and R2 = 10 kΩ (R2/R1 = 4.55 typ), ±10 % resistor ratio tolerance, and 250 mW power dissipation - used for digital load switching and IC input control in automotive and industrial modules.
For engineers reviewing the PDTD123YT/APGVL datasheet, PDTD123YT/APGVL pinout, PDTD123YT/APGVL application, or PDTD123YT/APGVL equivalent, key selection criteria include guaranteed 500 mA DC output current, defined VI(on)/VI(off) thresholds (0.5–1.4 V / 0.4–1 V), collector-emitter saturation voltage ≤0.3 V at IC = 50 mA/IB = 2.5 mA, and SOT23 footprint compatibility with automated assembly.
Technical Context
This RET integrates two precision thin-film resistors (R1 = 2.2 kΩ, R2 = 10 kΩ) directly into an NPN silicon die to form a single-input, single-output active switch with fixed base biasing. It eliminates external resistors while maintaining predictable turn-on/off behavior across −40 °C to +100 °C ambient.
The device operates as a saturated switch: input voltage applied to Pin 1 controls conduction between Pin 3 (collector) and Pin 2 (emitter), with built-in R1–R2 network setting base current and enabling direct logic-level drive without external pull-up/down components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial bus interfaces. |
| IO | 500 mA - guaranteed continuous DC output current; supports driving relays, LEDs, and small solenoids. |
| R1 | 2.2 kΩ ±30 % - input bias resistor defining base current; sets minimum drive strength for TTL/CMOS logic compatibility. |
| R2/R1 | 4.55 ±10 % - fixed feedback ratio ensuring stable saturation and consistent gain-independent switching. |
| VCE(sat) | ≤0.3 V at IC = 50 mA, IB = 2.5 mA - low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| Ptot | 250 mW at Tamb ≤25 °C - thermal limit for SOT23 package; requires PCB copper area for sustained 500 mA operation. |
| VI(on) | 0.5–1.4 V - input voltage range guaranteeing reliable turn-on with standard 3.3 V or 5 V microcontroller GPIOs. |
| Cc | 7 pF - collector junction capacitance; ensures <10 ns propagation delay in digital switching applications. |
Pinout & Package
SOT23 (TO-236AB) surface-mount plastic package, 3-pin, 1.3 mm × 2.8 mm footprint, 0.95 mm height, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base via R1) | Logic-level signal entry point; connects internally to R1, then to base node - no external base connection required. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common return path for load current and internal resistor network. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., relay coil, LED anode); sinks up to 500 mA when on. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in R1–R2 bias network | Eliminates 2 external resistors, reducing BOM count and PCB real estate by ≥3 mm² per channel. |
| ±10 % R2/R1 ratio tolerance | Ensures consistent hFE-independent saturation across production lots, avoiding batch-dependent threshold shifts. |
| 0.3 V VCE(sat) at rated current | Reduces conduction loss to ≤150 mW at 500 mA, enabling thermally constrained designs without heatsinking. |
| Direct 3.3 V/5 V logic interface | VI(on) ≤1.4 V and VI(off) ≥0.4 V allow robust switching with standard MCU I/O without level-shifting circuitry. |
| SOT23 footprint compatibility | Supports high-speed pick-and-place assembly and reflow soldering per IPC-J-STD-020; compatible with BC817 layout. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output |

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 |
|---|---|---|---|
| BC817-40,215 | No integrated resistors; requires external RB and RBE; hFE = 250–630 (wide spread); VCE(sat) = 0.7 V @ 500 mA. | Higher design overhead for biasing; less predictable switching thresholds; higher conduction loss. | Select when adjustable gain or higher VCEO (45 V) is needed; not drop-in for RET layouts. |
| DTC123YK-7-F | Same R1/R2 values (2.2 kΩ/10 kΩ), but SOT346 package; Ptot = 250 mW; identical VI(on)/VI(off) specs. | Larger footprint; lower thermal performance on same PCB area; same electrical behavior. | Choose for legacy SOT346 board reuse or where larger pad spacing improves manufacturability. |
Compared with BC817-40 and DTC123YK-7-F, PDTD123YT/APGVL delivers identical RET functionality in the smallest SOT23 footprint, with verified 500 mA capability and tighter R2/R1 tolerance - optimizing space, thermal margin, and production yield in high-density digital I/O designs.

FAQ
What is the maximum continuous collector current for PDTD123YT/APGVL?
The device is rated for 500 mA DC output current under specified thermal conditions (Tamb ≤25 °C, FR4 PCB with standard footprint). At elevated ambient temperatures or reduced copper area, derating applies - e.g., 350 mA at 70 °C ambient per Figure 2 in the datasheet.
Can PDTD123YT/APGVL be used with 3.3 V microcontroller GPIOs?
Yes. Its VI(on) range (0.5–1.4 V) ensures reliable turn-on with 3.3 V logic, and VI(off) (0.4–1 V) provides noise margin against false triggering. No level shifter or external pull-up is required for direct interface.
How does the built-in R2 resistor affect switching behavior?
R2 (10 kΩ) provides base-emitter feedback that stabilizes the operating point, reduces sensitivity to hFE variation, and ensures fast turn-off by discharging base charge - resulting in consistent 100 ns typical turn-off delay across temperature and process corners.
Is PDTD123YT/APGVL pin-compatible with BC817 in SOT23?
No. BC817-40 in SOT23 uses emitter-collector-base pinout (1=E, 2=C, 3=B), whereas PDTD123YT/APGVL uses input-GND-output (1=BviaR1, 2=E, 3=C). Layout redesign is required; it is not a drop-in replacement.
