ZLNB153X8TC

Product Overview

ZLNB153X8TC from Diodes Incorporated is a satellite receiver LNB support / polarisation switch controller used in RF, microwave or high-speed receiver signal-chain designs. This description focuses on practical RF function, operating range, interface requirements and sourcing relevance for engineering and procurement teams.

The exact suffix should be checked against the original BOM because RF performance, package, temperature range and reel format may vary across closely related orderable part numbers.

Key Features

• Manufacturer: Diodes Incorporated
• Part Number: ZLNB153X8TC
• Device Type: satellite receiver LNB support / polarisation switch controller
• RF Function: LNB tone and polarity switch controller providing logic outputs from voltage-sensitive inputs for satellite receiver feed control
• Frequency / Band: LNB support/controller IC for 13/18 V polarisation and 22 kHz tone-control systems rather than a broadband RF signal path
• Core Specification 1: Designed for twin, quad or multiple-feed universal LNB designs depending on part number
• Core Specification 2: Voltage-sensitive inputs control LNB polarisation selection
• Core Specification 3: Supports local oscillator selection and downfeed disable functions in applicable ZLNB201x devices
• Core Specification 4: Replaces discrete logic in satellite receiver LNB support circuits
• Core Specification 5: Package family: N8/Q16/X8/JA16 classes according to suffix
• Supply / Bias: operates from LNB/control supply environment per Diodes/Zetex device variant
• Interface / Output: voltage-sensitive input pins with logic outputs for LNB switch control
• Operating Temperature: satellite receiver support IC operating temperature class per exact datasheet
• Design Notes: Confirm the exact ordering suffix, package option, temperature grade and application circuit before replacing the part in an existing RF design.

Applications

Satellite receiver LNBs, multi-feed LNB assemblies, set-top box front-end accessories and dish receiver control circuits.

Repair and production support for LNB controller boards where control thresholds and package pinout must match.

Quality & Sourcing

Antrex Electronics can support sourcing for ZLNB153X8TC through available stock checks, BOM consolidation and alternative-lot review. For RF and microwave components, packaging condition, date code, MSL handling and original labeling should be checked before shipment.

For project builds, repair support or shortage coverage, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers manage risk when sourcing discontinued, legacy or hard-to-find RF misc ICs and modules.
