Product details
Overview
LC03-6R2G from onsemi is a low-capacitance, SO-8 packaged ESD protection diode array designed for bidirectional clamping of two high-speed I/O lines (e.g., USB 1.1 D+/D−). It delivers 2000 W peak power (8 × 20 µs), clamps to ≤15 V at 50 A and ≤20 V at 100 A, and exhibits ≤12 pF inter-pin capacitance - enabling signal integrity preservation in <480 Mbps data interfaces.
For engineers reviewing the LC03-6R2G datasheet, pinout, applications, or equivalent options, key selection criteria include its dual-line differential/common-mode surge protection capability, IEC 61000-4-2/4-4/4-5 compliance, SOIC-8 footprint compatibility, and verified performance in T1/E1 linecard and USB port protection circuits.
Technical Context
The LC03-6R2G integrates six anode-connected steering diodes and one common cathode in a single SO-8 package, enabling simultaneous protection of two independent high-speed data paths. Its architecture supports both line-to-line (differential) and line-to-ground (common-mode) transient suppression configurations without external components.
It operates with a 6.8 V minimum reverse breakdown voltage (VBR), maintains ≤20 nA reverse leakage at 5 V, and achieves clamping voltages validated per IEC 61000-4-5 (95 A, 8/20 µs) and Bellcore 1089 (100 A, 2/10 µs), making it suitable for intra-building telecom surge environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Power Dissipation | 2000 W (8 × 20 µs waveform): sustains multi-kW transients without failure in telecom/data line surge events |
| Clamping Voltage @ 50 A | ≤15 V (8 × 20 µs): limits downstream IC stress below logic-level damage thresholds for USB 1.1 receivers |
| Clamping Voltage @ 100 A | ≤20 V (8 × 20 µs): meets Bellcore 1089 intra-building surge immunity requirements |
| Inter-pin Capacitance | 8.0–12 pF @ 1 MHz, 0 V: preserves signal rise/fall times and minimizes bit error rate in 12–480 Mbps links |
| ESD Withstand | ±15 kV air / ±8 kV contact (IEC 61000-4-2): exceeds industrial-grade ESD immunity requirements for exposed ports |
| Breakdown Voltage | 6.8 V min @ 1 mA: ensures reliable conduction onset before 5 V rail overvoltage damages connected PHYs |
| Operating Temperature | −55 °C to +150 °C: supports deployment in extended-temperature industrial and telecom equipment |

IC Role / Device Role / Timing Role: Bidirectional clamping diode array placed directly at connector pins to shunt ESD energy to ground before reaching USB transceiver IC. Use Value: Prevents latch-up or permanent damage to USB PHYs while maintaining <12 pF loading to preserve 12 Mbps signal integrity and meet USB-IF eye diagram specs. |
Use Scenario: Safeguarding T1/E1 line interface circuitry in telecom central office cards, DSLAMs, or PBX systems against metallic and common-mode lightning surges. IC Role / Device Role / Timing Role: Dual-channel surge suppressor connected across Tip-Ring pairs on transmit/receive lines to clamp both differential and common-mode transients per Bellcore 1089. Use Value: Enables compliance with intra-building surge immunity requirements without adding transformers or gas discharge tubes - reducing BOM count and board space. |
| Industrial Serial Interface Protection | Legacy Data Acquisition System I/O |
Use Scenario: Hardening RS-422/RS-485 ports on programmable logic controllers (PLCs), motor drives, or SCADA RTUs against field wiring ESD and inductive switching noise. IC Role / Device Role / Timing Role: Low-capacitance steering diode array placed at physical layer interface to divert transients away from differential line drivers/receivers. Use Value: Maintains signal fidelity up to 10 Mbps while providing ≥15 kV ESD immunity - eliminating intermittent communication faults in harsh factory environments. |
Use Scenario: Securing analog/digital I/O channels on legacy data loggers, test equipment, or instrumentation where hot-plug cables introduce ESD risk during maintenance. IC Role / Device Role / Timing Role: Dual-path transient voltage suppressor used on front-panel connectors to protect ADC inputs, digital isolators, and level-shifting buffers. Use Value: Adds <20 V clamping protection with sub-12 pF loading - preventing measurement offset drift or digital input false triggering without degrading bandwidth. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1002-01WTG | Lower peak power (300 W), higher capacitance (15 pF), SOD-323 package (single-line) | Targeted at single-line, lower-energy ESD events; unsuitable for 100 A surge or dual-line protection | Select only for cost-sensitive, low-speed (<2 Mbps), single-I/O designs where SO-8 footprint is not required |
| CM1213A-04SO | Quad-channel (4-line), 12 pF typical, 350 W peak power, SO-16 package | Supports four I/O lines but lacks 2000 W surge rating; rated for IEC 61000-4-5 only up to 30 A | Choose when protecting >2 lines simultaneously and board space allows SO-16; avoid for Bellcore 1089 or high-current lightning scenarios |
Compared with SP1002-01WTG and CM1213A-04SO, LC03-6R2G uniquely delivers dual-line protection with 2000 W surge capability and sub-12 pF loading in SO-8 - making it the only option among the three qualified for T1/E1 linecards and USB 1.1 ports requiring full IEC/Bellcore certification.

FAQ
Is LC03-6R2G still in active production?
No - LC03-6R2G was officially discontinued by onsemi as of July 2025 (Rev. 6 datasheet). However, Aetrix Electronics maintains legacy inventory with full traceability and offers lifecycle support including obsolescence forecasting, cross-reference guidance, and last-time-buy coordination for ongoing production programs using LC03-6R2G.
What is the exact pin configuration for LC03-6R2G in differential mode protection?
In differential (line-to-line) mode, LC03-6R2G connects I/O Line 1 between pins 1 and 4, I/O Line 2 between pins 5 and 8, and ties pins 2, 3, 6, and 7 to ground. This configuration routes transients across the internal diode pairs without referencing system ground, preserving common-mode rejection in balanced interfaces like USB or RS-422.
Does LC03-6R2G require external biasing or current-limiting resistors?
No - LC03-6R2G is a passive diode array with no internal active circuitry. It requires no bias voltage, control signals, or series current-limiting resistors. Its operation relies solely on silicon PN junction conduction above VBR; standard PCB layout practices (short traces, solid ground plane) are sufficient for optimal performance.
Can LC03-6R2G be used for USB 2.0 or higher-speed interfaces?
No - LC03-6R2G's 8–12 pF inter-pin capacitance and 20 V clamping at 100 A make it unsuitable for USB 2.0 (480 Mbps) or faster interfaces, where <3 pF loading and tighter clamping are required. It is validated only for USB 1.1 (12 Mbps) and legacy telecom/data rates up to 10 Mbps.
How does LC03-6R2G differ from LC03-6R2 (non-G) variant?
The LC03-6R2G is the Pb-free version of LC03-6R2, with identical electrical specifications, SOIC-8 package dimensions, and pinout. The "G" suffix denotes RoHS-compliant termination; both share the same maximum ratings, clamping behavior, and application schematics - differing only in solder alloy composition and JEDEC marking.
