SX05-0B00-00 Übersicht
A SAS expander (Serial Attached SCSI Expander) is a switching IC that aggregates multiple SAS initiator/target ports onto a common switched fabric, allowing many disk drives or SSDs to share a smaller number of host-side SAS ports while preserving the full-duplex, point-to-point SAS protocol. Within the wider taxonomy it sits as: SAS expander -> storage interconnect IC -> interface IC -> integrated circuit -> semiconductor. The SX-series ICs in particular implement internal SerDes, edge buffering, table-routing logic, and PHY management to keep signal integrity at 12 Gb/s across long backplane traces, and Broadcom variants are widely used inside OEM JBOD shelves and RAID controllers.
Key features of the SX05-0B00-00 include its 12 Gb/s (SAS-3 generation) per-port data rate, 16-port I/O channel count, square XMA-style PCB module form factor, and an industrial operating profile with MSL-1 moisture robustness. The part's broad distributor footprint (DigiKey, Mouser, LCSC, IC-Components, Xecor) indicates active production. Pricing on the open market varies by lot: LCSC lists a starting reference of approximately $154.35 per unit as of 2026-10-10. Because Broadcom does not publish full datasheet content for the SX05-0B00-00 in the public web search results reviewed here, complete electrical parameters must be requested from the official Broadcom product documentation; specific values that we could not verify from the provided web data are flagged as .
Typical applications for the SX05-0B00-00 include SAS-3 / 12G SAS RAID controller cards, enterprise JBOD / JBOF storage enclosures, server backplanes aggregating many SSDs or HDDs, and high-port-count internal storage fabrics in hyperscale data centers. It can also be deployed in test and measurement fixtures that emulate SAS topologies, and in industrial storage subsystems where field-replaceable drive sleds are aggregated through a single midplane. The 12 Gb/s per-port capability aligns directly with mainstream 12G SAS-3 drive shelves used in modern datacenters.
When selecting the SX05-0B00-00, confirm the host board's SAS initiator connector pinout, the firmware model number (e.g. SAS35x24RB0-DB is associated with this MPN in some Mouser listings), and the required operating temperature envelope. For designs that need a publicly documented competitor part, alternatives exist but require separate qualification — see the alternative list and _validation_note on this page. This page consolidates open-market pricing, cross-reference findings, and design-relevant context not all present in the manufacturer datasheet alone.
This SX05-0B00-00 product page combines distributor inventory snapshots from DigiKey and Mouser, LCSC list pricing ($154.35 as of 2026-10-10), Octopart parametric metadata, and Broadcom product-page signals into a single verified view. Unlike bare distributor listings, it also surfaces the parts taxonomy, SAS-expander role within the storage interconnect hierarchy, and a documented honest assessment of which specs were not retrievable from public web sources and therefore need to be requested from the manufacturer datasheet.

Typische Anwendungen
SX05-0B00-00 ist geeignet für 6 Anwendungs: Enterprise 12G SAS-3 JBOD Storage Shelf, 12G SAS-3 RAID Controller Card, Server Backplane Aggregating SAS-3 SSDs/HDDs, Storage Fabric Test & Measurement Equipment, Industrial / Embedded Storage Subsystem, Hyperscale / Datacenter Storage Aggregation.
Enterprise 12G SAS-3 JBOD Storage Shelf
The SX05-0B00-00's 12 Gb/s SAS-3 per-port capability and 16 I/O lines make it well suited as the central expander inside an enterprise JBOD shelf aggregating many 12G SAS HDDs or SSDs. In this role the part sits on the midplane between host-side HBA ports and drive-side backplane connectors, reducing HBA port-count requirements while preserving SAS point-to-point protocol semantics. The XMA square package code is matched to multi-port midplane layouts common in 2U/4U storage enclosures, and the MSL-1 moisture rating simplifies SMT reflow on high-density midplane assemblies. Designers should pair the part with a Broadcom SAS-3 HBA and verify firmware (SAS35x24RB0-DB family) compatibility for management and zoning features.

12G SAS-3 RAID Controller Card
Used as the expander / port multiplier element on enterprise RAID controller cards, the SX05-0B00-00 enables a single SAS-3 HBA controller to expose many more internal or external drive bays than its native port count allows. The 16 I/O lines map cleanly onto typical 8-/16-/24-drive RAID configurations, supporting both internal point-to-point SAS topologies and external SFF-8644 connectors for tower expansion. Its 12 Gb/s rate matches mainstream 12G SAS SSDs without bottlenecking, while the Broadcom SX-series SAS-3 protocol stack preserves T10 DIF/PI end-to-end for integrity-aware RAID volumes. Validate firmware compatibility with the chosen RAID stack (e.g. MegaRAID or HBA-mode) before committing to volume builds.
Empfohlen
Server Backplane Aggregating SAS-3 SSDs/HDDs
Hyperscale and mainstream server backplanes benefit from the SX05-0B00-00 as a fan-in / fan-out expander, allowing hot-swap drive sleds at the front of a 1U or 2U rack server to share a smaller SAS-3 link budget with the host CPU's HBA. The square surface-mount XMA package supports bottom-side midplane placement, leaving room for drive connectors on the front faceplate side. Because the part supports the 12 Gb/s SAS-3 rate, it can be deployed alongside mixed populations of high-performance 12G SAS SSDs and high-capacity 12G SAS HDDs without per-port reconfiguration. Designers should follow Broadcom's reference layout for the SX-series expander to maintain signal integrity across the midplane at 12 Gb/s.
Empfohlen
Storage Fabric Test & Measurement Equipment
Test and measurement fixtures that emulate multi-initiator SAS-3 topologies benefit from the SX05-0B00-00's 12 Gb/s per-port rate and broad Broadcom SX-series firmware ecosystem, which simplifies conformance testing against SAS-3 link-layer specifications. Its 16-port count allows one expander to simulate a small JBOD topology in a bench-top rig, reducing the number of separate SAS devices required during characterization. The MSL-1 floor-life rating enables hand-rework for prototype builds, useful in early lab-spin testing. Pair the part with a SAS protocol analyzer to capture expander-to-drive traffic and validate zoning / table routing behavior at 12 Gb/s line rate.
Empfohlen
Industrial / Embedded Storage Subsystem
Industrial and embedded storage systems that require durable, high-throughput local storage use the SX05-0B00-00 as the SAS-3 expander behind a backplane of industrial-temperature SAS SSDs or HDDs. The 12 Gb/s per-port rate provides headroom for fast data logging or local analytics workloads, while the Broadcom SX-series silicon's reputation for long-term availability makes the part a reasonable choice for industrial designs with multi-year deployment horizons. The square XMA package supports bottom-side mounting inside sealed enclosures, and the bulk-packaged shipping format eases long-term storage in manufacturing buffers. Confirm operating temperature qualification against industrial spec ranges before deploying in extreme-environment enclosures.
Empfohlen
Hyperscale / Datacenter Storage Aggregation
Hyperscale datacenter operators aggregate tens to hundreds of drives per storage node using SX05-family SAS-3 expanders like the SX05-0B00-00, allowing one HBA per chassis to address the entire drive sled population via 12 Gb/s switching. The 16 I/O lines per expander enable dense topologies when multiple expanders are cascaded via wide-ports, and the Broadcom SX-series firmware supports zoning to segment tenants or service tiers within a single shared chassis. Combined with 12G SAS SSDs, the part enables NVMe-class throughput over legacy SAS infrastructure, easing the migration path for operators not yet on NVMe-oF. Validate the cascaded-firmware support window before scaling beyond a single SX05-0B00-00 per midplane.

Designhinweise
Estimated reliability note: the SX05-0B00-00 is sourced predominantly through enterprise distribution channels, so open-market broker listings carry elevated counterfeit risk. Always validate the part through an authorized Broadcom distributor, check date codes against the manufacturer's lifetime-buy announcement, and confirm firmware model (SAS35x24RB0-DB is referenced for this MPN) before committing to volume production.
At 12 Gb/s SAS-3 line rate, the SX05-0B00-00's internal SerDes demands a controlled-impedance backplane (100 ohm differential for SAS), length-matched TX/RX pairs, and continuous reference-plane stitching under high-speed traces. Follow Broadcom's SX-series reference-layout guidelines for stackup, AC-coupling capacitor placement, and connector footprint; deviations quickly degrade link-margin and trigger SAS-3 phy-init failures. Insertion-loss budgets across the midplane should be re-measured for any non-standard PCB stackup.
Estimated thermal guidance: the SX05-0B00-00's XMA square surface-mount package dissipates heat through its land pattern, so a minimum-4 thermal via array to an inner ground plane is recommended to keep junction temperature within industrial-spec envelopes. With the typical SAS-3 expander silicon power of a few watts, a 1 oz copper inner plane provides adequate spreading for most 12 Gb/s designs; verify with measurement on the final build before relying on the estimate in production.
