IMD9AT108

Overview

The IMD9AT108 is a dual digital transistor array manufactured by ROHM Semiconductor, featuring one NPN and one PNP transistor within an SMT6 (SOT-457) surface-mount package. It operates with a maximum collector-emitter voltage of 50V and supports continuous collector currents up to 100mA for both polarities. The device integrates internal biasing resistors to simplify circuit design, offering a typical input resistance configuration suitable for general switching applications. With a power dissipation rating of 300mW and a maximum operating temperature of +150°C, it provides reliable performance in compact electronic systems.

Feature Summary

• Integrates complementary NPN and PNP transistors in a single compact package
• Includes built-in biasing resistors to reduce external component count
• Supports high-speed switching with a maximum operating frequency of 250 MHz

Applications

• General-purpose signal switching circuits
• Logic level translation interfaces
• Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix AT108 against official ROHM documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure compatibility with RoHS directives if required by the target application. Cross-reference the Mouser part number 755-IMD9AT108 for accurate distributor identification and datasheet access. Confirm lead times directly with authorized suppliers as production schedules may vary.

Selection Notes

Select this component when a complementary pair of pre-biased transistors is needed in a minimal footprint. The SOT-457 package is suitable for space-constrained designs requiring both NPN and PNP functions. Verify that the 50V voltage rating and 100mA current capacity meet the specific load requirements of the target circuit before finalizing the design.
