AT-31011-TR1G

Overview

The AT-31011-TR1G is an NPN silicon RF bipolar transistor designed for low-current applications. It operates at frequencies up to 30 GHz with a gain bandwidth product of 10 GHz. The device features a minimum DC collector-to-base current gain (hFE) of 70. Maximum ratings include a collector-emitter voltage (VCEO) of 5.5 V, an emitter-base voltage (VEBO) of 1.5 V, and a continuous collector current of 16 mA. It offers a typical small-signal gain of 13 dB and supports lead-free construction.

Procurement Notes

This component is officially classified as obsolete by Broadcom Limited and is no longer manufactured. Availability is restricted to existing stock or third-party distributors. Verify the specific revision status and authenticity through authorized channels before procurement, as supply chain continuity cannot be guaranteed from the manufacturer.

Selection Notes

Select this part for high-frequency NPN switching or amplification tasks requiring low current handling. Ensure the application voltage does not exceed the 5.5 V collector-emitter rating. Consider the 16 mA current limit when designing bias networks. Evaluate thermal management requirements given the SOT-143 package constraints for continuous operation.

Part Context

The AT-31011-TR1G belongs to the AT series of RF bipolar transistors from Broadcom Limited. It is functionally similar to the AT-31033-TR1G but may differ in specific electrical characteristics. Both parts are discontinued products within the company's discrete semiconductor portfolio, reflecting a shift toward newer integrated solutions.

Replacement Considerations

The BFR106E6327HTSA1 is listed as a similar substitute part number. Verify pin compatibility and electrical specifications against original datasheets before substitution.
