Product details
Overview
PDTA123JM,315 from Nexperia is a PNP resistor-equipped transistor (RET) in a leadless ultra-small SOT883 (SC-101) package, designed for digital switching applications with −100 mA output current capability, built-in bias resistors R1 = 2.2 kΩ and R2/R1 ratio of 21, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTA123JM,315 datasheet, PDTA123JM,315 pinout, PDTA123JM,315 application, or PDTA123JM,315 equivalent, this device serves as a space-optimized, cost-saving alternative to discrete BJT + resistor networks in IC input control and low-power load switching circuits where board area and assembly cost are critical.
Technical Context
This PNP RET integrates a silicon transistor with two monolithically embedded resistors: R1 (2.2 kΩ) connects base to input, and R2 (47 kΩ) connects base to emitter, enabling single-pin digital drive without external bias components. It operates with VCEO = −50 V and supports VI(on) ≤ −0.75 V at IC = −5 mA.
The device delivers hFE ≥ 100 at IC = −10 mA and VCE = −5 V, exhibits VCEsat ≤ −100 mV under same conditions, and maintains stable off-state behavior with VI(off) ≥ −0.6 V at IC = −100 μA - all verified across −40 °C to +100 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive logic interfaces. |
| IO | −100 mA: Continuous output current rating; sufficient for driving LED indicators, small relays, or logic inputs. |
| R1 | 2.2 kΩ ±30%: Input bias resistor value; sets base current for predictable turn-on with standard CMOS/TTL logic levels. |
| R2/R1 | 21: Fixed feedback resistor ratio; ensures stable saturation and prevents thermal runaway during conduction. |
| VCEsat | ≤ −100 mV at IC = −5 mA, IB = −0.25 mA: Low saturation voltage minimizes power loss and heat generation in switching mode. |
| hFE | ≥ 100 at VCE = −5 V, IC = −10 mA: DC current gain guarantees reliable switching margin with typical microcontroller GPIO drive. |
| Ptot | 250 mW at Tamb ≤ 25 °C: Total power dissipation limit; supports operation up to +100 °C ambient with derating per Fig 1. |
Pinout & Package
Package: SOT883 (SC-101), leadless ultra-small plastic package; body dimensions 1.0 × 0.6 × 0.5 mm; 3 solder lands; reflow-only assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level control signal directly from MCU or gate output. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides return path for load current and R2 reference. |
| 3 | Output (collector) | Switched high-side output node; sinks current from load connected between VCC and this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 (2.2 kΩ) + R2 (47 kΩ) eliminates need for two external resistors, reducing BOM count and layout area. |
| AEC-Q101 qualified | Qualified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
| Ultra-compact footprint | SOT883 package occupies only 0.6 mm² PCB area - ideal for space-constrained modules like sensor nodes and infotainment controls. |
| Low VI(on) threshold | On-state input voltage ≤ −0.75 V at IC = −5 mA enables direct interface with 3.3 V and 5 V logic families without level shifting. |
| Thermal robustness | Rth(j-a) = 500 K/W on FR4 with 70 µm copper strip line; supports continuous operation up to +100 °C ambient with proper layout. |
Applications
| Automotive Door Module | Industrial PLC Input Stage |
|---|---|
|
Use Scenario: Switching of LED status indicators and small solenoid drivers in door control units. IC Role / Device Role / Timing Role: PNP RET acts as a grounded-emitter switch, sinking current from 12 V loads controlled by microcontroller GPIOs. Use Value: Eliminates discrete resistor placement and reduces assembly cost by 2 components per channel while maintaining AEC-Q101 compliance. |
Use Scenario: Level translation and isolation of 24 V field signals into 3.3 V FPGA or microcontroller I/O pins. IC Role / Device Role / Timing Role: Functions as a digital input buffer with built-in pull-up via R2, converting industrial voltage levels to logic-compatible thresholds. Use Value: Enables direct connection of 24 V sensors without external voltage dividers or optocouplers, cutting bill-of-materials and board space. |
| Consumer Wearable Power Control | Medical Sensor Interface |
|
Use Scenario: Enabling/disabling low-power subsystems (e.g., Bluetooth radio, accelerometer) in hearables and smart bands. IC Role / Device Role / Timing Role: High-side load switch controlled by application processor; provides clean power gating with minimal quiescent current. Use Value: Achieves <1 µA leakage (ICEO ≤ −1 µA) in off-state, extending battery life in always-on wearable devices. |
Use Scenario: Isolating analog front-end circuitry from digital control lines in portable patient monitors. IC Role / Device Role / Timing Role: Digital isolator replacement for non-isolated but noise-sensitive signal paths requiring galvanic separation of control and sensing domains. Use Value: Reduces EMI susceptibility through controlled edge rates and eliminates optocoupler latency (typical 1–5 µs propagation delay). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC123JM | NPN complement with identical SOT883 package, R1 = 2.2 kΩ, R2/R1 = 21; requires inverted logic drive. | Suitable for low-side switching where emitter connects to GND and collector drives load to VCC. | Select when circuit topology favors NPN configuration or existing design uses complementary logic polarity. |
| BC857BW,115 | Discrete PNP BJT in SOT323; no integrated resistors; requires external R1/R2; hFE = 200–450, VCEO = −45 V. | Offers higher gain and tighter VCEO tolerance but increases component count and layout complexity. | Choose when precise bias tuning, higher current gain, or legacy compatibility with BC847/857 footprints is required. |
Compared with PDTC123JM, the NPN counterpart shares footprint and resistor values but reverses switching polarity; versus BC857BW, the RET reduces part count and layout area at the expense of fixed bias ratios and slightly lower VCEO margin.

FAQ
What is the maximum operating temperature for PDTA123JM,315?
The junction temperature limit is 150 °C, and the ambient operating range is −65 °C to +150 °C. Derating begins above 25 °C ambient, with total power dissipation dropping linearly to zero at 150 °C per Figure 1 in the datasheet. Thermal resistance is 500 K/W on FR4 with 70 µm copper strip line.
Can PDTA123JM,315 be used in high-frequency switching applications?
No - it is optimized for DC and low-frequency digital switching (≤100 kHz). Its transition frequency fT is 180 MHz only under specific test conditions (VCE = −5 V, IC = −10 mA), but switching speed is limited by internal resistor time constants and typical rise/fall times exceed 1 µs. Use dedicated high-speed switches for >1 MHz operation.
Is wave soldering supported for the SOT883 package?
No - reflow soldering is the only recommended method per Section 11 of the datasheet. The SOT883 package lacks leads suitable for wave soldering; its land-pattern design (Fig 17) specifies solder paste volume and reflow profile requirements. Wave soldering risks solder bridging and insufficient wetting on the bottom-terminated terminals.
How does the built-in R2 resistor affect off-state leakage?
R2 (47 kΩ) pulls the base toward emitter potential, ensuring strong turn-off even with floating inputs. This results in ICEO ≤ −1 µA at VCE = −30 V and Tj = 25 °C, and ≤ −5 µA at 150 °C - significantly lower than discrete BJT alternatives without base pull-down, improving system reliability in noisy environments.
