Product details
Overview
PDTC123YM,315 from Nexperia is an NPN resistor-equipped transistor (RET) in SOT883 (SC-101) package, featuring integrated bias resistors R1 = 2.2 kΩ and R2/R1 = 4.5, rated for VCEO = 50 V and IO = 100 mA DC, used for compact logic-level switching in space-constrained consumer and portable electronics.
For engineers reviewing the PDTC123YM,315 datasheet, PDTC123YM,315 pinout, PDTC123YM,315 application, or PDTC123YM,315 equivalent, key selection criteria include built-in resistor ratio tolerance (3.6–5.5), ultra-small 1.0 × 0.6 × 0.5 mm footprint, thermal resistance of 500 K/W, and guaranteed VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA.
Technical Context
This RET integrates two precision thin-film resistors (R1 = 2.2 kΩ ±30%, R2 = 10 kΩ) directly into the NPN silicon die, eliminating external base bias components. It operates as a single-stage digital switch with defined turn-on/off thresholds: VI(on) = 1.15 V (typ.) at IC = 20 mA and VI(off) = 0.75 V (typ.) at IC = 100 μA.
The device uses standard planar epitaxial NPN technology with junction temperature limit of 150 °C and is qualified per AEC-Q101 for industrial reliability. Its SOT883 package enables reflow-only assembly on FR4 PCBs with 60 μm copper traces, supporting high-density routing in wearables and IoT edge nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V logic interfaces and 3.3/5 V microcontroller I/O drivers. |
| IO | 100 mA DC - Continuous output current capability; sufficient to drive LEDs, small relays, or logic gates without external buffering. |
| R1 | 2.2 kΩ (1.54–2.86 kΩ) - Input bias resistor sets base current; defines minimum drive strength required from upstream logic. |
| R2/R1 | 4.5 (3.6–5.5) - Feedback-to-input resistor ratio; determines saturation stability and noise immunity against leakage-induced false turn-on. |
| VCE(sat) | ≤150 mV at IC=10 mA/IB=0.5 mA - Low saturation voltage minimizes power loss and self-heating in battery-powered applications. |
| Ptot | 250 mW at Tamb ≤25 °C - Total power dissipation limit; requires thermal derating above 25 °C ambient per Rth(j-a) = 500 K/W. |
| hFE | ≥35 at VCE=5 V, IC=5 mA - Minimum DC current gain ensures reliable switching margin under worst-case process and temperature variation. |
Pinout & Package
SOT883 (SC-101) is a leadless ultra-small plastic package measuring 1.0 × 0.6 × 0.5 mm with three solder lands on the bottom surface. It supports only reflow soldering and is optimized for automated placement in high-volume portable electronics manufacturing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level input signal; must be driven above VI(on) ≈ 1.15 V to activate. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for both input and output paths. |
| 3 | Output (collector) | Switched output node; sinks up to 100 mA when active; connects to load between VCC and this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 network | Eliminates 2 external resistors, reducing BOM count and PCB area by ≥1.2 mm² in typical 3.3 V GPIO interface designs. |
| Guaranteed VI(off) | 0.75 V (typ.) ensures robust immunity to noise and leakage currents below 100 μA, preventing unintended turn-on in low-power sleep states. |
| Ultra-compact SOT883 | 1.0 × 0.6 mm footprint fits within tight spacing constraints of Bluetooth earbuds, smartwatches, and medical patches. |
| Reflow-only qualification | Validated for JEDEC J-STD-020D moisture sensitivity level 1; supports high-yield, no-clean reflow processes without pre-bake. |
| AEC-Q101 qualified | Stress-tested for automotive-grade reliability including HTOL, TC, and HAST; suitable for industrial control and harsh-environment IoT gateways. |
Applications
| LED Indicator Control | Microcontroller I/O Expansion |

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 |
|---|---|---|---|
| PDTC123YK | SOT346 (SC-59A) package; larger 3.0 × 1.7 mm footprint; Ptot = 250 mW; same R1/R2 values and electrical specs. | Better thermal performance in moderate-power applications; less suitable for ultra-thin wearables due to height and land pattern. | Select when board layout allows larger footprint and higher thermal mass is beneficial for intermittent 100 mA loads. |
| PDTC123YU | SOT323 (SC-70) package; 2.2 × 1.35 mm; Ptot = 200 mW; slightly lower power rating and higher Rth(j-a) = 625 K/W. | Compatible with legacy SC-70 pick-and-place tooling; lower max current derating above 60 °C ambient. | Choose for compatibility with existing SC-70 assembly lines where SOT883 reflow profile validation is not feasible. |
Compared with PDTC123YK and PDTC123YU, PDTC123YM offers the smallest footprint and identical electrical performance, making it optimal for next-generation miniaturized devices where PCB area is at a premium and thermal management relies on system-level heatsinking rather than package-level dissipation.

FAQ
Is PDTC123YM,315 compatible with lead-free reflow soldering profiles?
Yes. PDTC123YM,315 is qualified for lead-free reflow per JEDEC J-STD-020D, with peak temperature tolerance up to 260 °C for 30 seconds. Its SOT883 package uses matte tin terminations and is rated MSL1, requiring no pre-bake prior to assembly.
What is the maximum operating temperature for continuous 100 mA output current?
At IO = 100 mA, power dissipation is ~15 mW (assuming VCE(sat) = 150 mV). With Rth(j-a) = 500 K/W, junction temperature rise is 7.5 °C above ambient. Therefore, continuous operation at 100 mA is viable up to Tamb = 142.5 °C (150 °C − 7.5 °C), well within its 150 °C Tj limit.
Can PDTC123YM,315 replace a standard NPN BJT like BC847 in existing designs?
No - PDTC123YM,315 is not a drop-in replacement for discrete BJTs. Its internal R1/R2 network fixes base biasing, so it cannot be used in analog amplifier configurations or circuits requiring adjustable base current. It is intended only for digital switching where fixed resistor ratios are acceptable.
Does the marking code 'G7' on PDTC123YM correspond to a specific date or lot traceability?
The 'G7' marking is a standardized device identification code per Nexperia's ordering system, not a date code. Traceability to wafer lot, fab location (Malaysia), and assembly site is maintained in Aetrix's certified supply chain records and can be provided upon request for quality investigations or audits.
