EMB10T2R Descripción general
A digital transistor (also called a bias-resistor-built-in transistor, or BRT) is a discrete BJT with one or two monolithic resistors integrated on the same die, replacing the discrete base-resistor network that designers would otherwise place around a standard transistor. It belongs to the hierarchy: digital transistor -> pre-biased BJT array -> bipolar transistor array -> discrete semiconductor. The integration of bias resistors eliminates roughly three external components per channel and removes the need for precise resistor matching, which simplifies PCB layout, shrinks BOM count, and improves switching consistency in high-volume manufacturing.
Key features include a collector-emitter voltage rating of 50V, continuous collector current of 100mA per channel, transition frequency of 250 MHz, and total device power dissipation of 150 mW. The package is a 6-lead EMT6 measuring approximately 1.6 mm x 1.6 mm, making it among the smallest dual-transistor products on the market. The integrated bias resistors are 10 kohm typical, and the design supports direct drive from MCU GPIO pins or logic-level signals without external biasing components.
The architecture uses a PNP silicon epitaxial planar die with polysilicon bias resistors, providing tight R1/R2 tolerance and good thermal matching between the two channels. The symmetrical dual-channel layout simplifies PCB routing for complementary switching or differential amplifier front-ends.
Typical applications include interface circuits, level shifters, signal buffering, LED driver for museum display panels, and pre-amplifier differential amplification in portable devices. It is also used as a high-frequency oscillator building block and gate driver for low-power MOSFETs in industrial control modules.
When designing with this device, note that Rohm has designated the EMB10 as Not Recommended for New Designs. For new designs, evaluate the UMB10N (industry equivalent) or IMB10A (industry equivalent) families. The dual-channel matching makes it well-suited for differential pairs where channel-to-channel gain and Vbe tracking matter.

Aplicaciones típicas
EMB10T2R es adecuado para 6 aplicacións: Interface Circuit and Level Shifter, LED Driver for Compact Displays, Differential Pre-Amplifier Front-End, High-Frequency Oscillator Building Block, MOSFET Gate Driver for Low-Power Switches, Signal Buffering for Industrial Control.
Interface Circuit and Level Shifter
The EMB10T2R is well suited for logic-level interface and level-shifting circuits between low-voltage MCUs and higher-voltage loads. Each PNP channel rated 50Vceo and 100mA can switch a 5V/12V rail from a 3.3V GPIO output. The built-in 10kohm bias resistor eliminates the external base-resistor network that a discrete BJT would otherwise require, reducing BOM by 2 components per channel and improving switching consistency in volume production.
Recomendado
LED Driver for Compact Displays
The EMB10T2R drives small-signal LEDs in compact display modules, indicator panels, and museum display backlight strips. Each PNP channel at 100mA continuous collector current can directly switch an LED string at low duty cycle without external base resistors. The 250MHz transition frequency ensures clean PWM dimming at audio-band frequencies, eliminating visible artifacts. The 1.6mm x 1.6mm EMT6 footprint enables high-density LED array designs.
Recomendado
Differential Pre-Amplifier Front-End
The EMB10T2R dual matched PNP channels support differential pre-amplifier circuits for sensor signal conditioning. Channel-to-channel Vbe tracking from a common substrate improves common-mode rejection ratio compared to two discrete transistors. The 250MHz fT ensures adequate bandwidth for audio-frequency signals up to 20kHz with low phase distortion. The integrated bias resistors simplify bias-point design versus discrete implementations.
Recomendado
High-Frequency Oscillator Building Block
The EMB10T2R operates as a high-frequency oscillator building block in low-power oscillator modules and clock-generation circuits. The 250MHz transition frequency fT supports oscillator operation well above 100MHz when paired with appropriate LC tank circuits. The dual matched channels enable balanced oscillator topologies that suppress even-order harmonics, and the integrated bias resistors reduce stray capacitance from external components.
Recomendado
MOSFET Gate Driver for Low-Power Switches
The EMB10T2R drives the gate of low-power MOSFETs in industrial control modules and power-management subcircuits. Each PNP channel at 100mA collector current provides sufficient gate-charge current for small-signal MOSFETs in switching regulator feedback paths. The 50Vceo rating supports 24V industrial bus rail interfaces. The built-in bias resistor simplifies the gate-drive network versus discrete transistor implementations.
Recomendado
Signal Buffering for Industrial Control
The EMB10T2R buffers digital signals in industrial control modules where noise immunity and signal integrity matter. The 50Vceo rating tolerates 24V industrial bus transients, and the 100mA collector current drives opto-isolator LEDs and relay coils directly. The dual matched channels enable complementary buffer pairs with consistent propagation delay. The EMT6 package supports -55C to +150C junction operation for harsh industrial environments.

Notas de diseño
Estimated: at 100mA continuous collector current and 30V Vce, the EMB10T2R dissipates approximately 3W per channel (impossible - this exceeds the 150mW package rating). The absolute maximum package dissipation is 150mW total, so the practical safe operating current at any meaningful Vce must be limited. Use the derating curve in the Rohm datasheet to compute allowable Ic at your specific Vce and ambient temperature.
The EMT6 package has a thermal pad on the underside that should be soldered to a copper pour for best thermal performance. For high-density layouts, connect the thermal pad to the collector node (pins 3/4) to provide additional heatsinking. Use 2oz copper where possible to keep junction temperature below 150C maximum at the application's worst-case ambient.
Do not use EMB10T2R in new designs - Rohm has designated it Not Recommended for New Designs. For new designs, use UMB10N or IMB10A as industry equivalents. Also note that the built-in bias resistor is 10kohm typical; if your drive circuit expects a different R1, use a different member of the EMB family (e.g., EMB3T2R) or use a discrete transistor with external biasing.
The 250MHz fT supports clean switching at audio and low-RF frequencies. For high-frequency oscillator circuits, ensure PCB layout minimizes stray capacitance at the base/emitter nodes since the integrated bias resistors do not isolate the base from parasitic effects. Place bypass capacitors close to the supply nodes if used as an oscillator.
