IMT17T208

Overview

The IMT17T208 is a dual PNP bipolar junction transistor array manufactured by Rohm Semiconductor. It features a maximum collector current of 500mA and a collector-emitter breakdown voltage of 50V. The device operates with a transition frequency of 200MHz and dissipates up to 300mW of power. It is housed in an SMT6 (SC-74, SOT-457) surface-mount package. Key electrical characteristics include a DC current gain of 120 at 100mA and 3V, and a saturation voltage of 600mV at 50mA base and 500mA collector current. The component supports a junction temperature of 150°C.

Feature Summary

• Dual PNP configuration within a compact surface-mount footprint
• High-speed operation capability with 200MHz transition frequency
• Low saturation voltage for efficient switching performance

Applications

• General-purpose switching circuits
• Signal amplification stages
• Logic interface buffers

Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Rohm Semiconductor. Verification of availability requires checking authorized distributors for remaining stock or approved substitute part numbers. Ensure any replacement components meet the original electrical specifications and pinout compatibility before integration into designs.

Selection Notes

Designers should evaluate the 500mA continuous collector current limit and 50V voltage rating against circuit requirements. The dual PNP structure allows for complementary configurations in a single package. Consider thermal management for the 300mW power dissipation in the small SMT6 package during selection.

Part Context

The IMT17T208 belongs to the MT17 series of dual PNP transistors from Rohm. It is designed for applications requiring two matched PNP devices in a minimal surface-mount form factor. The product line focuses on providing reliable switching solutions for consumer and industrial electronics.
