AT-31033-BLKG

Overview

The AT-31033-BLKG is an NPN silicon bipolar transistor manufactured by Broadcom Limited, designed for low-current RF applications. It operates at a maximum frequency of 30 GHz with a minimum DC collector-base gain (hFE) of 70. The device supports a maximum collector-emitter voltage (VCEO) of 5.5 V and an emitter-base voltage (VEBO) of 1.5 V. Continuous collector current is rated at 16 mA, with power dissipation of 150 mW. It functions within a temperature range of -65°C to +150°C and is housed in an SOT-23 surface-mount package.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before integration into production schedules. Ensure storage conditions meet humidity sensitivity standards to maintain device integrity during assembly processes.

Selection Notes

Select this component when designing circuits requiring high-frequency performance at minimal bias currents. The SOT-23 package facilitates compact PCB layouts for portable devices. Evaluate thermal management needs given the 150 mW power dissipation limit and ensure the operating environment stays within the specified -65°C to +150°C range for reliable long-term operation.

Part Context

This part belongs to the AT-31033 series of high-performance NPN bipolar transistors optimized for wireless market applications. The BLKG suffix typically denotes specific packaging or tape-and-reel configuration details consistent with Broadcom's standard product coding conventions for surface-mount components.

Replacement Considerations

The AT-31033-BLK is a compatible variant using the same die but in an SOT-143 package. Verify pinout compatibility and thermal characteristics when substituting, as the physical footprint differs. No other direct cross-model replacements are confirmed in public documentation.
