Key Features
- Dual NPN transistor configuration with 2 separate elements sharing a 6-pin SC-74 (SOT23-6) package, saving board space versus 2 discrete packages
- Built-in bias resistors with a 1:1 ratio eliminate external base resistors, simplifying PCB layout and reducing component count
- 50 V collector-emitter voltage (VCEO) and 50 mA maximum collector current (IC) suit a broad range of low-power switching and interface applications
Applications
The IMH11AT110 is commonly used in logic-level switching circuits, microcontroller GPIO buffers, and LED driver interfaces where two independent NPN switching transistors with integrated bias resistors can replace four or more discrete components. Its compact SC-74 package and built-in resistors make it ideal for space-constrained consumer electronics, portable devices, and industrial control boards requiring simple, reliable transistor switching at up to 50 V and 50 mA per channel.

Frequently Asked Questions
What are the key voltage and current ratings of the IMH11AT110 that define its safe operating range?
The IMH11AT110 is rated at a maximum collector-emitter voltage (VCEO) of 50 V and a maximum collector current (IC) of 50 mA per transistor element. The minimum DC current gain (hFE) is 30, and the built-in bias resistor ratio is 1:1. These parameters define it as a low-power digital switching transistor suitable for logic interface and LED driving applications.
How does the built-in bias resistor in the IMH11AT110 simplify circuit design compared to a discrete transistor?
With a built-in bias resistor ratio of 1:1, the IMH11AT110 eliminates the need for external base resistors on both NPN transistor elements. This reduces the total component count by at least 2 resistors per device, simplifies PCB routing in the 6-pin SC-74 (SOT23-6) package, and ensures consistent switching behavior without manual resistor value selection for typical 3.3 V or 5 V logic-level drive signals.
In what types of embedded and consumer electronics circuits is the IMH11AT110 a practical choice?
The IMH11AT110 is a practical choice for microcontroller GPIO current-buffer circuits, relay driver stages, LED indicator switching at up to 50 mA per channel, and small-signal inverter or level-shifting circuits in consumer electronics and industrial equipment. The dual-element SC-74 package allows 2 independent switching channels in a footprint no larger than a single SOT-23 device, making it effective for space-constrained PCB designs.
What package does the IMH11AT110 use, and how does it affect PCB assembly and footprint?
The IMH11AT110 uses a 6-pin SC-74 package, which is equivalent to a SOT-23 6-pin surface-mount footprint. This compact package measures approximately 2.0 mm x 2.1 mm, enabling 2 NPN transistor channels to occupy the PCB area of a single small discrete transistor package. Its SMT format supports automated reflow soldering, making it compatible with standard PCB assembly lines.
