Product details
Overview
PRMH2 from Nexperia is a dual NPN resistor-equipped transistor (RET) in a DFN1412-6 (SOT1268) package, designed for digital switching and IC input control. It features 50 V VCEO, 100 mA per transistor output current, built-in bias resistors (R1 = 47 kΩ typ., R2/R1 = 1), and AEC-Q101 qualification for automotive use.
For engineers reviewing the PRMH2 datasheet, PRMH2 pinout, PRMH2 application, or PRMH2 equivalent, this device serves as a space- and cost-optimized replacement for discrete BC847/BC857 pairs in low-power digital logic interfacing, load switching, and microcontroller I/O buffering where board area and assembly count are critical.
Technical Context
The PRMH2 integrates two matched NPN transistors with monolithically embedded base bias networks-R1 connected between base and emitter, R2 between base and input-enabling single-resistor drive without external bias components. Each transistor operates independently with shared ground terminals but isolated collectors and inputs.
Its DFN1412-6 package provides thermal enhancement (Rth(j-a) = 261 K/W per device on FR4) and ultra-low profile (0.47 mm body height), supporting high-density automotive and portable electronics layouts where thermal management and mechanical clearance are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive rail and 3.3/5 V logic-level switching with margin. |
| IO | 100 mA per transistor - Continuous DC output current capability; sufficient for driving LEDs, small relays, or logic gates. |
| hFE | 80 min at VCE = 5 V, IC = 5 mA - Ensures reliable saturation with low base drive current in digital on/off operation. |
| R1 | 47 kΩ typical - Integrated base-emitter resistor enables direct microcontroller GPIO connection without external pull-down. |
| R2/R1 ratio | 1.0 ± 0.2 - Precise internal resistor matching ensures consistent turn-on threshold and noise immunity across both transistors. |
| VCE(sat) | 150 mV max at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating during sustained conduction. |
| Ptot | 480 mW per device at Tamb ≤ 25 °C - Enables dual-transistor operation within compact thermal envelope on standard FR4 PCB. |
Pinout & Package
PRMH2 uses the DFN1412-6 (SOT1268) leadless surface-mount package: 1.4 mm × 1.2 mm × 0.47 mm body, 0.5 mm max height, thermally enhanced bottom paddle, no leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter terminal of Transistor 1; common reference for TR1 base drive and collector load return path. |
| 2 | I1 | Base input of Transistor 1; accepts logic-level signal directly from MCU or gate output with built-in R1/R2 network. |
| 3 | O2 | Collector output of Transistor 2; active-high switch node for driving loads referenced to GND2 or shared supply. |
| 4 | GND2 | Emitter terminal of Transistor 2; independent ground reference enabling isolated load switching or level translation. |
| 5 | I2 | Base input of Transistor 2; electrically identical to I1 but isolated; supports dual independent control signals. |
| 6 | O1 | Collector output of Transistor 1; primary switching node for first load; shares no internal connection with O2. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two fully independent NPN transistors with integrated R1/R2 bias networks reduce BOM count by up to 8 passive components vs. discrete solutions. |
| AEC-Q101 qualification | Validated for automotive temperature range (−40 °C to +150 °C) and stress testing, enabling use in engine control modules and body electronics. |
| Ultra-thin DFN1412-6 package | 0.47 mm body height and 1.4 mm × 1.2 mm footprint saves >60% board area versus SO-8 or SOT-363 equivalents. |
| Low VCE(sat) and high hFE | 150 mV max saturation voltage and 80+ DC gain ensure full turn-on with ≤0.5 mA base current, compatible with 3.3 V GPIOs. |
| Matched R2/R1 ratio | 0.8–1.2 tolerance guarantees consistent VI(on)/VI(off) thresholds across both transistors, improving timing predictability in dual-control applications. |
Applications
| Automotive Body Control Module | Industrial PLC Input Stage |
|---|---|
|
Use Scenario: Level-shifting and buffering of 12 V sensor signals into 3.3 V microcontroller ADC or GPIO inputs. IC Role / Device Role / Timing Role: Dual-transistor RET acts as bidirectional digital interface: one channel conditions sensor enable, the other handles fault flag feedback. Use Value: Eliminates need for separate bias resistors and ESD protection diodes per channel, reducing component count and layout complexity while maintaining AEC-Q101 compliance. |
Use Scenario: Isolating and conditioning 24 V industrial fieldbus signals (e.g., RS-485 enable lines) before routing to FPGA or ASIC I/O banks. IC Role / Device Role / Timing Role: Each transistor functions as a dedicated high-side switch for bus direction control and fault isolation, sharing ground only at PCB level. Use Value: Independent GND1/GND2 terminals allow galvanic separation between control logic and field-side circuitry, improving noise immunity without optocouplers. |
| Consumer IoT Sensor Hub | Medical Wearable Power Sequencing |
|
Use Scenario: Enabling/disabling multiple low-power sensors (e.g., accelerometer, ambient light) based on MCU sleep/wake state. IC Role / Device Role / Timing Role: One transistor controls sensor VDD enable; the other manages interrupt line pull-up/pull-down configuration during state transitions. Use Value: Built-in bias resistors guarantee defined logic states during MCU reset or brown-out, preventing floating inputs and false wake events. |
Use Scenario: Sequencing power delivery to analog front-end (AFE) and Bluetooth SoC in battery-powered diagnostic patches. IC Role / Device Role / Timing Role: Dual RET provides precise, resistor-matched turn-on delays via RC time constants formed with external capacitors on I1/I2 pins. Use Value: Matched R2/R1 ratio ensures <±5% skew between sequencing edges, meeting tight 100 µs inter-rail delay requirements for low-noise AFE startup. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PRMD12 | NPN/PNP complement with identical package and bias resistor values; VCEO = 50 V, IO = 100 mA, but opposite polarity per channel. | Suitable for complementary push-pull outputs or level inversion where one channel requires sourcing and the other sinking. | Select when mixed-signal interfacing demands both sourcing and sinking capability in same footprint. |
| BC847BPDW1T1G | Discrete dual NPN in SOT-363; no built-in resistors; requires external bias network; hFE = 200–450, VCEO = 45 V, Ptot = 300 mW. | Higher gain and lower VCE(sat), but increases PCB area and assembly cost due to 4 extra resistors and larger package. | Choose when maximum current gain or tighter VCE(sat) tolerance is required and board space is not constrained. |
Compared with PRMD12, PRMH2 offers matched NPN-NPN behavior ideal for parallel digital control; compared with BC847BPDW1T1G, it trades higher hFE for significant BOM reduction and guaranteed resistor matching-critical for timing-critical dual-channel applications.

FAQ
Is PRMH2 pin-compatible with BC847/BC857 dual-transistor arrays?
No-PRMH2 uses a 6-pin DFN1412-6 (SOT1268) package with unique pin assignment (GND1, I1, O2, GND2, I2, O1), whereas BC847/BC857 arrays use SOT-363 or SC-74 packages with different pinouts and no integrated resistors. Direct replacement requires PCB redesign but eliminates four external resistors per channel.
Can PRMH2 be used in linear amplifier configurations?
No-the PRMH2 is optimized for digital switching, not analog amplification. Its built-in bias resistors fix the base operating point, and its hFE specification is given only at IC = 5 mA with no linearity data. Use discrete transistors like BC847B for small-signal amplification.
What is the function of the bottom thermal pad in the DFN1412-6 package?
The exposed copper pad on the underside of the DFN1412-6 package is electrically connected to GND1 and GND2 internally and serves as the primary thermal path. It must be soldered to a large PCB copper pour to achieve the specified Rth(j-a) = 261 K/W and prevent junction overheating at 100 mA continuous load.
Does PRMH2 support 1.8 V logic-level input drive?
Yes-VI(on) is specified at 1.6 V min (typ. 3 V) and VI(off) at 1.2 V max (typ. 0.8 V) at 25 °C, providing adequate noise margin for 1.8 V CMOS logic. At elevated temperatures, VI(on) decreases slightly, ensuring robust turn-on even at −40 °C to +100 °C operating range.
