Product details
Overview
PMBT3904YSRH from Nexperia is a dual NPN general-purpose transistor in SOT363-3 (SC-88) 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 switching and amplification in space-constrained PCBs.
For engineers reviewing the PMBT3904YSRH datasheet, PMBT3904YSRH pinout, PMBT3904YSRH application, or PMBT3904YSRH equivalent, key selection factors include per-transistor voltage/current limits, thermal resistance (Rth(j-a) = 357 K/W per device), dual-transistor layout compatibility, and SOT363-3 footprint constraints.
Technical Context
This double transistor contains two electrically isolated NPN silicon epitaxial planar devices sharing a common leadframe but no internal connection between TR1 and TR2. Each transistor operates independently with identical absolute maximum ratings and DC characteristics.
It supports linear amplification (VCE = 1 V, IC = 10 mA, hFE = 100–300) and switching (VCE(sat) = 750 mV max at IC = 10 mA/IB = 1 mA; ton = 70 ns max), with low leakage (ICBO ≤ 50 nA) and fT = 300 MHz typical at VCE = 20 V/IC = 10 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum collector-emitter voltage before breakdown; defines safe operating voltage headroom in low-voltage switching rails. |
| IC | 200 mA - Continuous collector current per transistor; sets upper limit for load drive capability in discrete logic-level switches. |
| hFE | 100–300 - DC current gain at VCE = 1 V, IC = 10 mA; determines required base drive current for saturation in amplifier or switch designs. |
| VCE(sat) | 750 mV max - Collector-emitter saturation voltage at IC/IB = 10; directly impacts conduction loss and power dissipation in saturated-switch operation. |
| Rth(j-a) | 357 K/W - Junction-to-ambient thermal resistance per device on FR4 PCB; governs temperature rise under 230 mW per-transistor or 350 mW total power dissipation. |
| fT | 300 MHz - Transition frequency at VCE = 20 V, IC = 10 mA; indicates usable bandwidth for small-signal amplification up to ~100 MHz. |
Pinout & Package
SOT363-3 (SC-88/TSSOP6) is a 6-pin, surface-mount plastic package measuring 2.2 mm × 1.35 mm × 0.95 mm with gull-wing leads and pin 1 index marking. Its compact footprint enables high-density placement in portable and IoT PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of TR1 | Low-impedance output node for TR1; connects to ground or emitter resistor in common-emitter configurations. |
| 2 | Base of TR1 | Control input for TR1; requires current-limited drive to achieve target hFE-based collector current. |
| 3 | Collector of TR2 | High-side output node for TR2; used as active load or switched output in dual-stage topologies. |
| 4 | Emitter of TR2 | Reference node for TR2; may be tied to TR1 emitter for differential pair biasing or kept separate for independent operation. |
| 5 | Base of TR2 | Independent control input for TR2; enables asynchronous switching or cascaded amplification without shared base drive. |
| 6 | Collector of TR1 | Primary output for TR1; commonly routed to pull-up resistors, LEDs, or downstream logic inputs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN topology | Two fully isolated transistors in one SOT363-3 package-reduces component count and board area by ~40% vs. two discrete SOT23 devices. |
| Low VCE(sat) | 750 mV max at IC = 10 mA ensures <10 mW conduction loss per transistor, critical for battery-powered signal routing. |
| High fT | 300 MHz typical enables stable small-signal gain up to 50 MHz with proper biasing and layout-suitable for RF front-end preamps. |
| Low leakage | ICBO ≤ 50 nA at VCB = 30 V minimizes standby current in always-on sensor interface circuits across industrial temperature range. |
Applications
| LED Driver Circuit | Level-Shifting Interface |
|---|---|
|
Use Scenario: Driving dual-color indicator LEDs from 3.3 V microcontroller GPIOs with independent anode control. IC Role / Device Role / Timing Role: Each NPN acts as a low-side switch; TR1 controls red LED, TR2 controls green LED with separate base resistors. Use Value: Eliminates need for two separate SOT23 transistors-saves 1.8 mm² PCB area and simplifies BOM while maintaining <1 µs switching response. |
Use Scenario: Translating 1.8 V logic outputs to 5 V-tolerant inputs in mixed-voltage MCU peripherals. IC Role / Device Role / Timing Role: TR1 configured as emitter-follower level shifter; TR2 provides inverted enable signal for bus isolation control. Use Value: Achieves sub-10 ns propagation delay with rail-to-rail swing-enables reliable SPI clock/data translation without external level-shift ICs. |
| Current Mirror Reference | Discrete Op-Amp Input Stage |
|
Use Scenario: Building matched current sources for precision analog sensor biasing in medical wearables. IC Role / Device Role / Timing Role: TR1 and TR2 form a monolithic current mirror with inherent thermal tracking due to shared die substrate. Use Value: Delivers <±2% current matching over −40 °C to +85 °C-improves ADC reference stability without laser-trimmed resistors. |
Use Scenario: Constructing discrete instrumentation amplifier front-ends for low-noise biopotential acquisition. IC Role / Device Role / Timing Role: TR1/TR2 serve as matched differential pair in common-emitter configuration with degeneration resistors. Use Value: NF = 5 dB at 10 Hz–15.7 kHz enables ECG-grade SNR; integrated matching reduces offset drift versus discrete SOT23 pairs. |
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 (higher gain spread); VCEO = 45 V; Ptot = 300 mW per device. | Higher gain enables lower base drive in high-impedance bias networks; 5 V higher VCEO suits 24 V industrial IO modules. | Select when tighter hFE binning or extended voltage margin is required-verify thermal derating at >150 °C ambient. |
| EMT17T2R | SOT563 package (smaller 1.6 × 1.6 mm); hFE = 120–270; VCEO = 50 V; Rth(j-a) = 420 K/W per device. | Smaller footprint saves 35% board area but increases thermal resistance-limits continuous IC to 150 mA at 70 °C ambient. | Choose for ultra-compact consumer wearables where size outweighs thermal performance; confirm solder joint reliability with wave reflow. |
Compared with BC847BDW1T1G and EMT17T2R, PMBT3904YSRH offers balanced gain consistency (100–300), proven thermal performance (357 K/W), and broad design support across industrial and automotive-qualified variants-making it optimal for cost-sensitive, thermally constrained dual-transistor functions.

FAQ
What is the maximum junction temperature for PMBT3904YSRH?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation above this value risks permanent degradation of hFE and increased leakage. Derating curves in Figure 1 show power must be reduced linearly above 25 °C ambient to maintain Tj ≤ 150 °C.
Can PMBT3904YSRH be used in linear amplification mode?
Yes-its hFE of 100–300 at VCE = 1 V and IC = 10 mA, combined with fT = 300 MHz, supports stable small-signal amplification up to ~50 MHz. Biasing must ensure VCE ≥ 1 V and IC ≤ 200 mA to avoid thermal runaway or saturation distortion.
Is there internal connection between TR1 and TR2?
No-TR1 and TR2 are fully electrically isolated transistors sharing only the physical package and leadframe. Pin 1 (E1), 2 (B1), 6 (C1) belong exclusively to TR1; pins 3 (C2), 4 (E2), 5 (B2) belong exclusively to TR2. No internal bond wires or substrate coupling exist between them.
What is the recommended reflow profile for SOT363-3 mounting?
Nexperia specifies JEDEC J-STD-020-compliant reflow: peak temperature 260 °C for ≤ 30 seconds, ramp-up rate ≤ 3 °C/s, and time above 217 °C of 60–150 seconds. Figure 9 provides exact solder land dimensions (2.35 × 0.6 mm per pad) and stencil aperture recommendations for 0.15 mm thickness.
