Product details

Dual NPN pre-biased transistor in a compact SOT-563 package

The ROHM Semiconductor EMH9T2R integrates two NPN pre-biased transistors in a single SOT-563 / SOT-666 package, each with a 10 kΩ base resistor (R1) and a 47 kΩ base-emitter resistor (R2). The 150 mW power dissipation limit per package sets the thermal budget for both channels combined.

Sizing the load: 50 V and 100 mA limits

The 300 mV saturation voltage at 250 µA base drive and 5 mA collector current gives a low on-state drop for logic-level loads.

Package and footprint for dense layouts

The SOT-563 / SOT-666 package (EMT6 supplier device package) is an ultra-small, 6-lead surface-mount package. The 0.5 mm lead pitch and compact body suit space-constrained designs such as portable electronics, sensor modules, and multi-channel I/O blocks.

Frequently asked questions

What is the minimum hFE of EMH9T2R?

The minimum DC current gain (hFE) is 68 at 5 mA collector current and 5 V VCE.

Is EMH9T2R RoHS compliant?

Yes, the EMH9T2R is ROHS3 compliant.

What is the equivalent or replacement for EMH9T2R?

The UMH9NTN is a pin-compatible functional equivalent with the same 10 kΩ base resistor and 47 kΩ base-emitter resistor values, same 50 V / 100 mA ratings, and same SOT-563 package. The EMG5T2R shares the same package and ratings but uses a 10 kΩ base resistor and 47 kΩ base-emitter resistor — verify the resistor values match your circuit before substituting.
