Product details
Overview
PMBT3904YS,115 from Nexperia is a dual NPN general-purpose transistor in SOT363-3 (TSSOP6) package, rated for 40 V VCEO, 200 mA IC, and DC current gain (hFE) of 100–300 at IC = 10 mA. It integrates two independent transistors on one die for compact signal switching and amplification in space-constrained PCBs.
For engineers reviewing the PMBT3904YS,115 datasheet, PMBT3904YS,115 pinout, PMBT3904YS,115 application, or PMBT3904YS,115 equivalent, key selection criteria include per-transistor voltage/current ratings, thermal derating on FR4, dual-transistor isolation, and SOT363-3 footprint compatibility with high-density routing.
Technical Context
This double transistor consists of two electrically isolated NPN silicon epitaxial planar devices sharing no internal connection-each has dedicated emitter, base, and collector terminals. Pin configuration supports independent biasing and operation of TR1 (Pins 1,2,6) and TR2 (Pins 4,5,3).
It operates within −55 °C to 150 °C ambient range, with junction temperature limited to 150 °C. Thermal resistance is 357 K/W (per device, junction-to-ambient on FR4), enabling stable performance in low-power analog and digital interface circuits without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum safe collector-emitter voltage per transistor with base open; defines upper rail limit for switching applications. |
| IC | 200 mA - Continuous collector current per transistor; sets load-driving capability in small-signal amplifiers or logic-level switches. |
| hFE | 100–300 - DC current gain at VCE = 1 V, IC = 10 mA; determines base drive requirements for saturation in switching designs. |
| VCE(sat) | 750 mV max at IC = 10 mA, IB = 1 mA - Low saturation voltage ensures minimal power loss and heat generation in on-state operation. |
| fT | 300 MHz - Transition frequency at VCE = 20 V, IC = 10 mA; supports RF amplification up to VHF band in low-noise receiver stages. |
| Ptot (per device) | 350 mW - Total power dissipation on FR4 PCB; defines maximum combined power handling before thermal derating applies. |
Pinout & Package
SOT363-3 (TSSOP6) is a 6-pin, surface-mount plastic package measuring 2.2 mm × 1.35 mm × 0.95 mm, optimized for automated placement and reflow soldering on fine-pitch PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Current sink node for first transistor; connects to ground or low-side load return path. |
| 2 | Base of TR1 | Control input for TR1; requires ~1 mA drive for full saturation at 10 mA collector load. |
| 3 | Collector of TR2 | Current source node for second transistor; routes switched output to VCC or pull-up network. |
| 4 | Emitter of TR2 | Current sink node for second transistor; enables independent grounding or cascaded biasing. |
| 5 | Base of TR2 | Independent control input for TR2; allows asynchronous or complementary switching with TR1. |
| 6 | Collector of TR1 | Current source node for first transistor; used for active loads or push-pull stage outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated NPN topology | Enables two independent switching/amplification paths in one footprint-reducing board area by ~40% vs. discrete SOT23 pairs. |
| Low VCE(sat) (750 mV max) | Minimizes conduction loss in battery-powered sensor interfaces and IO buffer circuits operating below 3.3 V. |
| High fT (300 MHz) | Supports clean amplification of clock harmonics and digital edge signals up to 100 MHz without phase distortion. |
| FR4-compatible thermal design | 357 K/W Rth(j-a) allows sustained 200 mA operation at 70 °C ambient without heatsinking or airflow. |
Applications
| LED Driver Pair | Logic-Level Translator |
|---|---|
Use Scenario: Driving dual-color indicator LEDs from microcontroller GPIO pins with separate anode/cathode control. IC Role / Device Role / Timing Role: Each transistor acts as a low-side switch, sinking current from LED cathodes while maintaining isolation between color channels. Use Value: Eliminates need for two separate SOT23 packages; reduces PCB area by 30% and simplifies layout routing near MCU headers. | Use Scenario: Translating 1.8 V logic outputs to 5 V TTL-compatible inputs in mixed-voltage industrial I/O modules. IC Role / Device Role / Timing Role: TR1 functions as level-shifting switch, TR2 provides inverted output for complementary signaling or enable/disable sequencing. Use Value: Achieves sub-70 ns propagation delay with <100 mV noise margin-meeting RS-422 receiver input thresholds reliably. |
| Audio Preamp Stage | Relay Driver Interface |
Use Scenario: Building a two-stage low-noise preamplifier for electret microphone signals in portable audio recorders. IC Role / Device Role / Timing Role: TR1 amplifies weak AC-coupled mic signal; TR2 provides gain staging and impedance matching to ADC input. Use Value: NF = 5 dB at 10 Hz–15.7 kHz enables SNR > 65 dB without external bypass capacitors or shielding. | Use Scenario: Controlling dual SPST relays in HVAC control panels using a single 3.3 V microcontroller output. IC Role / Device Role / Timing Role: Each transistor drives relay coil (12 V/40 mA) with independent base resistors and flyback diode integration points. Use Value: 200 mA IC rating supports 12 V coils up to 300 Ω; 230 mW per-transistor dissipation avoids thermal shutdown during burst operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BDW1T1G | Same SOT363-3 package; hFE = 200–450 at IC = 10 mA; VCEO = 45 V; higher gain spread but identical pinout. | Preferred where tighter hFE matching or higher voltage margin is required-e.g., 24 V industrial sensors. | Select when gain consistency across production lots is critical; verify base resistor values due to higher hFE min. |
| MMDT3904-7-F | SOT363-3; VCEO = 40 V; IC = 200 mA; hFE = 100–300; same electrical specs but RoHS-compliant lead finish differs. | Identical functional replacement; used in medical diagnostics equipment requiring legacy compliance documentation. | Choose for traceability to Diodes Inc. supply chain; no circuit redesign needed-pin-for-pin and thermal drop-in. |
Compared with BC847BDW1T1G and MMDT3904-7-F, PMBT3904YS,115 offers identical core switching performance with Nexperia's documented FR4 thermal derating curve and industry-standard marking (BC%), simplifying qualification in automotive-adjacent industrial programs.

FAQ
What is the maximum allowable continuous collector current per transistor?
The PMBT3904YS,115 supports 200 mA continuous collector current per transistor under Tamb ≤ 25 °C with proper PCB copper area. Derating begins above 25 °C per Fig. 1: at 70 °C ambient, max IC drops to ~140 mA per transistor to maintain Tj ≤ 150 °C.
Can TR1 and TR2 share a common emitter connection?
No-TR1 and TR2 are fully isolated; their emitters (Pins 1 and 4) are physically and electrically separate. Shared-emitter configurations require external wiring and introduce crosstalk risk; the device is designed for independent operation only.
Is this part qualified for automotive applications?
No-PMBT3904YS,115 is not AEC-Q101 qualified. Nexperia explicitly states in Section 14 that non-automotive qualified products are unsuitable for safety-critical systems. Use only in consumer, industrial, or communications equipment meeting IEC 61000-4 immunity standards.
What is the typical noise figure and where is it specified?
The typical noise figure is 5 dB, measured at VCE = 5 V, IC = 100 µA, RS = 1 kΩ, and frequency range 10 Hz to 15.7 kHz (Table 7). This value applies to low-frequency audio preamplifier use cases-not RF front-end applications.
