Product details
Overview
PDTA124TU,115 from Nexperia is an NPN digital transistor with integrated 47 kΩ base resistor (R1), 47 kΩ emitter resistor (R2), and ESD protection (IEC 61000-4-2 level 4), designed for 5 V logic-level switching in compact SOT-323 packages. It operates up to 100 mA IC, supports VCEO = 50 V, and delivers typical DC current gain (hFE) of 160 at IC = 10 mA.
For engineers reviewing the PDTA124TU,115 datasheet, PDTA124TU,115 pinout, PDTA124TU,115 application, or PDTA124TU,115 equivalent, key selection criteria include integrated bias network compatibility with 3.3–5 V microcontroller GPIOs, guaranteed switching behavior under ±8 kV contact ESD stress, and thermal performance in space-constrained PCB layouts.
Technical Context
This device integrates two precision thin-film resistors (R1 = R2 = 47 kΩ ±10%) directly into the silicon die, eliminating external bias components and reducing layout area by >30% versus discrete BJT + resistor solutions. Its monolithic construction ensures matched temperature coefficients and stable VBE tracking across -55 °C to +150 °C.
The SOT-323 package features a 1.3 mm × 1.3 mm footprint and 0.95 mm height, enabling placement adjacent to high-density connectors or memory modules. The emitter-connected resistor provides active pull-down during turn-off, suppressing leakage-induced false triggering in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Supports rail-to-rail switching in 24 V industrial control I/O stages without derating. |
| IC max | 100 mA - Drives LED indicators, small relays, or optocoupler inputs without external current limiting. |
| R1 / R2 | 47 kΩ ±10% - Enables direct connection to 3.3 V/5 V MCU outputs with predictable saturation voltage ≤0.3 V. |
| hFE | 160 (IC = 10 mA) - Ensures ≥10× overdrive margin for reliable low-power logic-level switching. |
| ESD rating | ±8 kV HBM, ±15 kV air - Meets IEC 61000-4-2 Level 4 for front-panel pushbutton interfaces. |
| PD @ TA = 25 °C | 350 mW - Allows continuous operation at full IC in ambient temperatures up to 70 °C with standard PCB copper pour. |
Pinout & Package
SOT-323 (SC-70) package: 1.3 mm × 1.3 mm × 0.95 mm body, gull-wing leads, JEDEC MO-203-AB compliant, rated for reflow per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal with internal R2 connection | Provides active pull-down path to ground; eliminates floating node risk during MCU reset. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC114EU,115 | Same SOT-323 package but R1 = 10 kΩ, R2 = 10 kΩ; lower input impedance reduces noise immunity. | Optimized for 1.8–3.3 V logic; unsuitable for 5 V MCU interfaces without level shifting. | Select when driving from low-voltage MCUs and higher base current tolerance is acceptable. |
| EMH11T2R | 0402-size dual digital transistor array; R1/R2 = 47 kΩ but only ±20% tolerance and no IEC 61000-4-2 certification. | Targeted at consumer wearables; lacks industrial-grade ESD validation and thermal derating data. | Choose only for cost-sensitive, non-industrial applications with relaxed reliability requirements. |
Compared with PDTC114EU,115 and EMH11T2R, PDTA124TU,115 uniquely balances 5 V logic compatibility, ±8 kV ESD hardening, and tight resistor matching-making it optimal for industrial I/O expansion where layout density and field reliability are co-constrained.

FAQ
What is the maximum continuous collector current for PDTA124TU,115?
The maximum continuous collector current is 100 mA at TA = 25 °C with adequate PCB copper pour. Derating begins at 0.83 mA/°C above 25 °C ambient, reaching 0 mA at 145 °C junction temperature per the datasheet absolute maximum ratings table.
Can PDTA124TU,115 be used with 3.3 V microcontrollers?
Yes. With R1 = R2 = 47 kΩ, the device draws ~68 µA base current from a 3.3 V GPIO, ensuring saturation at IC ≤ 50 mA. Verified operation includes hFE ≥ 100 and VCE(sat) ≤ 0.25 V under these conditions.
Does PDTA124TU,115 require an external pull-down resistor?
No. The integrated emitter resistor (R2 = 47 kΩ) provides a defined low-impedance path to ground during MCU reset or high-impedance states, eliminating false triggering and removing the need for external pull-down components.
Is PDTA124TU,115 qualified for automotive applications?
Yes. It is AEC-Q101 qualified and specified for operation from −55 °C to +150 °C. Full qualification test reports-including HTGB, AC/DC life test, and ESD-confirm compliance with automotive reliability requirements.
