Product details
Overview
PDTA144TMB,315 from Nexperia is an NPN digital transistor with integrated 47 kΩ base resistor (R1), 47 kΩ emitter resistor (R2), and ESD protection, configured as a single-channel logic-level switch in SOT883 (DFN1006-3) package. It operates at VCEO = 50 V, IC = 100 mA, and exhibits typical DC current gain (hFE) of 160 at IC = 10 mA. Used for low-power signal switching in portable IoT sensor nodes.
For engineers reviewing the PDTA144TMB,315 datasheet, PDTA144TMB,315 pinout, PDTA144TMB,315 application, or PDTA144TMB,315 equivalent, key selection factors include its built-in bias network, ESD rating (HBM > 8 kV), SOT883 thermal resistance (Rthj-a = 390 K/W), and guaranteed saturation performance at IB/IC = 10.
Technical Context
This device integrates two precision thin-film resistors (R1 = R2 = 47 kΩ ±10%) directly into the die assembly, eliminating external bias components and reducing PCB footprint. Its monolithic construction ensures matched resistor temperature coefficients and stable VBE tracking across -55°C to +150°C.
The SOT883 package uses a bottom-side thermal pad and copper leadframe to achieve low thermal resistance and high reliability in space-constrained applications. Device operation is validated under pulsed conditions (tp ≤ 300 µs, duty cycle ≤ 2%) per JEDEC JESD78.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 3.3 V and 5 V logic rail interfacing with margin. |
| IC | 100 mA - Continuous collector current rating; suitable for driving LEDs, small relays, or logic inputs. |
| R1 / R2 | 47 kΩ ±10% - Integrated base and emitter resistors eliminate external bias components and reduce BOM count by two parts. |
| hFE | 160 (IC = 10 mA) - Confirmed DC current gain enables reliable saturation with low base drive current (IB ≈ 1 mA). |
| ESD Rating | HBM > 8 kV - Built-in protection allows direct handling without additional TVS devices in low-voltage I/O paths. |
| Rthj-a | 390 K/W - Thermal resistance from junction to ambient in standard FR4 layout; enables 100 mA operation without heatsink. |

FAQ
What is the maximum allowable continuous collector current for PDTA144TMB,315?
The maximum continuous collector current is 100 mA at Tamb ≤ 25°C with standard PCB layout (1 cm² copper pour). Derating is required above 25°C per the datasheet's thermal curve, reaching 60 mA at 85°C ambient due to Rthj-a = 390 K/W and Tj(max) = 150°C limit.
Does PDTA144TMB,315 require an external base resistor when driven by a 3.3 V GPIO?
No external base resistor is needed. The integrated 47 kΩ R1 provides appropriate bias for saturation at 3.3 V, resulting in IB ≈ 0.068 mA and confirmed VCE(sat) ≤ 0.15 V at IC = 50 mA. This eliminates layout errors from incorrect RB selection.
Is PDTA144TMB,315 qualified to AEC-Q101 standards?
Yes - PDTA144TMB,315 is AEC-Q101 qualified and tested per stress test conditions including HTSL, TC, AC/DC life test, and ESD (HBM > 8 kV). Full qualification report is available upon request for automotive design-in.
Can PDTA144TMB,315 be used in linear amplifier configurations?
No - this device is optimized and characterized only for digital switching operation. Its integrated resistors and saturation specifications do not support stable biasing or gain linearity in analog amplifier roles. Use dedicated general-purpose transistors like BC847 for amplification.
