BLT99/SL

Product Overview

BLT99_SL is commonly associated with Freescale / NXP BLT99/SL, a legacy semiconductor component used in RF, communication or board-level replacement applications. Because full official public datasheet information for BLT99/SL is limited, the device should be handled as a legacy replacement part where the exact manufacturer, package style, top marking, electrical rating, frequency range and target circuit compatibility must be confirmed before purchase or repair use. It is suitable for RF equipment maintenance, communication boards, transmitter support circuits, legacy electronic assemblies and BOM review projects requiring the BLT99/SL ordering code.

Key Features

• Manufacturer: Freescale / NXP, according to public independent inventory listings

• Part Number: BLT99_SL

• Common Part Number Format: BLT99/SL

• Device Type: Legacy semiconductor component

• Product Category: RF transistor / specialized semiconductor component, subject to original datasheet confirmation

• Application Class: RF, communication equipment and board-level replacement applications

• Technology Note: Exact transistor technology and internal structure should be verified from the original manufacturer datasheet or physical part marking

• Polarity Note: NPN / PNP / MOSFET configuration should not be assumed without confirming the official datasheet

• Frequency Range: Exact operating frequency range should be verified from the original BLT99/SL datasheet and target circuit

• Output Power: RF output power rating should be confirmed from the original datasheet and application test conditions

• Voltage Rating: Collector / drain voltage rating should be verified from the official datasheet before replacement use

• Current Rating: Collector / drain current rating should be confirmed from manufacturer documentation and circuit requirements

• Package: Package style should be confirmed from product photos, original top marking and board footprint

• Mounting Type: Package-dependent mounting; confirm whether the supplied part is through-hole, flange, ceramic RF package or surface-mount version

• Suffix Note: SL suffix may indicate a package, selection, lead form or ordering variant depending on the original manufacturer system

• Replacement Note: Do not substitute with other BLT-series RF transistors without confirming pinout, package, frequency response, gain and power rating

• Board Compatibility: Original PCB footprint, bias network, matching circuit and heat dissipation design must be checked before installation

• RF Matching Requirement: Input/output matching networks should be matched to the original application frequency and impedance

• Thermal Requirement: Proper heatsink, soldering condition and RF package mounting should be verified according to the target equipment

• Datasheet Availability: Full official public datasheet is not commonly available from open sources

• Lifecycle Note: This should be treated as a legacy or hard-to-find component; availability is usually through independent distributors or surplus stock channels

• Typical Use: RF board repair, communication equipment maintenance, transmitter circuit support and legacy semiconductor replacement

• Key Features: Freescale / NXP legacy ordering code, BLT99/SL format, RF or communication equipment application, and board-level replacement support
