Product details
Overview
PDTA115TT from Nexperia is a PNP resistor-equipped transistor (RET) with integrated 100 kΩ base bias resistor (R1), designed for general-purpose switching and digital interface applications in compact surface-mount designs. It features −50 V collector-emitter voltage, −100 mA DC output current, and SOT23 package with 1.1 mm × 0.9 mm footprint - commonly used in LED drivers, logic-level translators, and microcontroller I/O buffering circuits.
For engineers reviewing the PDTA115TT datasheet, PDTA115TT pinout, PDTA115TT application, or PDTA115TT equivalent, key selection criteria include its built-in R1 value (70–130 kΩ), guaranteed hFE ≥ 100 at IC = −1 mA, VCEsat ≤ −150 mV at IC = −5 mA/IB = −0.25 mA, and thermal resistance of 500 K/W in free air - critical for low-power discrete logic interfacing.
Technical Context
This device integrates a single PNP bipolar junction transistor with one external-base resistor (R1 = 100 kΩ typical, no R2 connection), eliminating need for discrete bias components. Its open-emitter configuration enables direct drive from CMOS/TTL outputs without level-shifting circuitry.
It operates as a saturated switch under standard logic drive conditions: IB flows through R1 to base, enabling controlled IC conduction with predictable saturation voltage and gain. The SOT23 package supports reflow-only soldering per JEDEC J-STD-020, with maximum junction temperature of 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial control rails. |
| IO (DC) | −100 mA: Continuous collector current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 70–130 kΩ: Integrated base pull-up resistor tolerance range; sets input impedance and ensures reliable turn-on with 3.3 V/5 V logic. |
| hFE | ≥100 at VCE = −5 V, IC = −1 mA: Minimum DC current gain guarantees stable switching margin across temperature. |
| VCEsat | ≤ −150 mV at IC = −5 mA, IB = −0.25 mA: Low saturation voltage minimizes power loss and heat generation in on-state. |
| Ptot | 250 mW at Tamb ≤ 25 °C: Total power dissipation limit defines maximum continuous switching duty in ambient conditions. |
| Cc | 3 pF at VCB = −10 V, f = 1 MHz: Collector capacitance impacts high-frequency response in digital switching applications. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package; 3 leads; body dimensions 1.1 mm × 0.9 mm × 1.3 mm; standard reflow-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level input signal to enable transistor conduction. |
| 2 | GND (emitter) | Common reference node; tied to system ground in most switching configurations. |
| 3 | Output (collector) | Switched output terminal; sinks current to load when transistor is active (e.g., LED cathode or relay coil). |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistor R1 | 100 kΩ ±30% eliminates external component count and PCB space for basic switching circuits. |
| Guaranteed hFE ≥ 100 | Ensures consistent turn-on behavior across manufacturing lots and temperature ranges (−40 °C to +150 °C). |
| Low VCEsat ≤ −150 mV | Reduces conduction losses and self-heating during sustained on-state operation. |
| SOT23 package compatibility | Supports automated pick-and-place assembly and standard 4 mm pitch tape-and-reel handling (3000 pcs/reel). |
| JEDEC-compliant reflow profile | Enables single-pass lead-free soldering without thermal damage or parametric shift. |
Applications
| LED Driver Circuit | Microcontroller I/O Buffer |
|---|---|
Use Scenario: Driving indicator LEDs from 3.3 V GPIO pins in portable medical devices. IC Role / Device Role / Timing Role: PNP RET acts as low-side sink switch, translating logic-high output into LED-on state. Use Value: Built-in R1 ensures reliable turn-on with minimal external parts; VCEsat ≤ −150 mV limits LED current variation across supply voltage drift. |
Use Scenario: Level-shifting between 5 V legacy peripherals and 3.3 V MCU I/O ports. IC Role / Device Role / Timing Role: Inverting interface buffer providing voltage translation and current gain. Use Value: hFE ≥ 100 maintains noise margin; SOT23 footprint allows dense placement near MCU pins without routing congestion. |
| Logic Inverter Stage | Power Supply Enable Switch |
Use Scenario: Implementing non-inverting logic function using two cascaded inverters in battery-powered sensor nodes. IC Role / Device Role / Timing Role: Single-stage inverter with defined propagation delay and rail-to-rail swing. Use Value: Predictable R1 and VCEsat enable accurate timing modeling; low Cc (3 pF) preserves edge integrity up to 10 MHz. |
Use Scenario: Enabling/disabling auxiliary 12 V rail in automotive infotainment head units via MCU command. IC Role / Device Role / Timing Role: High-side switch controller (with external P-channel MOSFET) or direct low-side load switch. Use Value: −100 mA IO rating supports typical enable-current loads; −50 V VCEO accommodates transients in 12 V systems. |
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 |
|---|---|---|---|
| PDTC115TT | NPN complement with identical R1 = 100 kΩ, same SOT23 package, but opposite polarity. | Used where active-high switching or sourcing current is required instead of sinking. | Select PDTC115TT when interfacing with open-collector outputs or requiring source-mode drive. |
| PDTA123TT | R1 = 2.2 kΩ (vs. 100 kΩ), lower input impedance, higher base current for faster switching. | Better suited for high-speed digital interfaces (>1 MHz) where reduced propagation delay is critical. | Choose PDTA123TT only if drive strength and speed outweigh power efficiency concerns. |
Compared with PDTC115TT, PDTA115TT provides complementary PNP functionality for sink-switching roles; versus PDTA123TT, it trades switching speed for lower input current and improved static power efficiency in always-on logic interfaces.

FAQ
What is the function of the internal resistor in PDTA115TT?
The internal 100 kΩ resistor (R1) connects between pin 1 (base) and the input signal source, providing automatic base biasing. This eliminates the need for an external pull-up or pull-down resistor, simplifying circuit design and reducing component count in digital switching applications such as LED control and logic level translation.
Can PDTA115TT be used in place of a standard PNP transistor like BC807?
No - PDTA115TT is not a drop-in replacement for BC807 because it includes an integrated 100 kΩ base resistor and uses a different pinout (base-emitter-collector vs. emitter-base-collector). Substitution requires schematic modification to remove external bias resistors and verify drive compatibility with the fixed R1 value.
What is the maximum operating temperature for PDTA115TT?
The absolute maximum junction temperature is 150 °C, and the storage temperature range is −65 °C to +150 °C. At ambient temperatures up to 85 °C, derating applies: total power dissipation must be reduced linearly from 250 mW at 25 °C to zero at 150 °C based on Rth(j-a) = 500 K/W.
Is PDTA115TT compatible with lead-free reflow soldering processes?
Yes - PDTA115TT is qualified for lead-free reflow soldering per JEDEC J-STD-020. The SOT23 package supports peak reflow temperatures up to 260 °C for 30 seconds, with ramp rates and soak profiles matching standard Class 3 IPC requirements for high-reliability assembly.
