Product details
Overview
DSL03-024SC6 from STMicroelectronics is a low-capacitance transient voltage suppression (TVS) diode array designed for bidirectional I/O protection on high-speed DSL lines, with a standoff voltage of 24 V, clamping voltage of 55 V at 16 A (8/20 µs), typical junction capacitance of 0.5 pF, and compliance with ITU-T K20/21, GR-1089, and IEC 61000-4-5 Level 2. It protects ADSL/VDSL2 line drivers in telecom infrastructure.
For engineers reviewing the DSL03-024SC6 datasheet, DSL03-024SC6 pinout, DSL03-024SC6 application, or DSL03-024SC6 equivalent, key selection criteria include bidirectional I/O clamping performance, sub-1 pF capacitance at 1 MHz, 24 V VRM rating, surge robustness up to 16 A (8/20 µs), and SOT23-6L package compatibility with high-density DSL modem PCB layouts.
Technical Context
The DSL03-024SC6 integrates two back-to-back TVS diodes per channel in a monolithic silicon structure, enabling symmetrical clamping for AC-coupled DSL signals without polarity sensitivity. Its low-leakage design (0.2 µA @ 25 °C) minimizes signal distortion in high-impedance line driver interfaces.
It operates across –40 °C to +125 °C junction temperature range and maintains peak pulse power capability up to Tj = 125 °C, supporting reliable operation in thermally constrained DSLAM and CPE environments where ambient temperatures exceed 85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRM) | 24 V - Maximum continuous reverse working voltage before leakage exceeds 0.2 µA; sets operating margin above VDSL2 line bias. |
| Clamping Voltage (VCL) | 55 V @ 16 A (8/20 µs) - Peak voltage seen by protected line driver during worst-case surge; ensures safe margin below IC breakdown. |
| Junction Capacitance (CJ) | 0.5 pF @ 2 V, 1 MHz - Enables <1% signal attenuation at 30 MHz; supports VDSL2 Annex M (30 MHz) data rates. |
| Peak Pulse Current (IPP) | 16 A (8/20 µs) - Withstands GR-1089-compliant 500 A (2/10 µs) surges when used with gas tube coordination. |
| Leakage Current (IRM) | 0.2 µA @ 25 °C - Prevents DC loading on high-Z line driver outputs; avoids baseline shift in analog front-end stages. |
| Operating Junction Temp | –40 to +125 °C - Supports deployment in unventilated DSL modems and outdoor DSLAM cabinets without derating. |
Pinout & Package
DSL03-024SC6 is housed in a RoHS-compliant, lead-free SOT23-6L package (JEDEC MO-178AA), with 1.75 mm × 2.9 mm footprint, 1.3 mm max height, and thermal pad-compatible layout per Figure 8 in DocID022325 Rev 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O Channel A Anode | Input/output terminal for first protected DSL pair; connects directly to line driver output via series impedance. |
| 2 | GND | Common reference for both TVS channels; must be low-inductance connection to system ground plane. |
| 3 | I/O Channel A Cathode | Completes bidirectional clamping path for Channel A; forms low-capacitance path to GND during overvoltage. |
| 4 | I/O Channel B Cathode | Second clamping path cathode; enables dual-line protection (e.g., tip/ring or pair A/pair B) in single package. |
| 5 | GND | Redundant ground terminal for improved current sharing and reduced ground loop inductance. |
| 6 | I/O Channel B Anode | Second protected I/O terminal; supports independent or differential DSL line protection configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional I/O clamping | Enables protection of AC-coupled DSL signals without polarity constraints; eliminates need for external series capacitors. |
| 0.5 pF typical capacitance | Preserves signal integrity up to 30 MHz; meets VDSL2 Annex M insertion loss requirements (<0.5 dB at 17 MHz). |
| 55 V clamping at 16 A | Provides 2.3× margin over VDSL2 line driver absolute maximum rating (24 V), preventing latch-up during surge events. |
| GR-1089 & ITU-T K21 compliance | Validated for telecom-grade surge immunity including 2.5 kV AC power fault and 6 kV 10/700 µs induced surges. |
| SOT23-6L footprint | Enables direct replacement of legacy 6-pin TVS arrays; supports automated placement and reflow in high-volume modem manufacturing. |
Applications
| VDSL2 Class AB Modem Interface | ADSL2+ Line Card Protection |
|---|---|
Use Scenario: Protecting differential VDSL2 line drivers in customer premises equipment (CPE) with Class AB topology and ±12 V supply rails. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed between line driver output and transformer primary, absorbing common-mode surges while preserving signal fidelity.

Use Value: 55 V clamping voltage provides 2.3× safety margin over ADSL2+ driver's 24 V abs max rating, eliminating field failures from GR-1089-compliant surges. |
| VDSL2 Class H Remote Terminal | Multi-Pair xDSL Distribution Panel |
Use Scenario: Protecting VDSL2 Class H line drivers in remote terminals serving multiple subscribers over long copper loops (>1 km). IC Role / Device Role / Timing Role: Low-leakage (0.2 µA) TVS array maintaining DC bias stability on high-impedance driver outputs under elevated ambient temperature. Use Value: Stable leakage across –40 to +125 °C prevents baseline drift in analog front-end, avoiding false disconnect detection during thermal cycling. | Use Scenario: Consolidated surge protection for 4-pair xDSL distribution panels in building entry points handling ADSL/VDSL coexistence. IC Role / Device Role / Timing Role: Dual-channel TVS in single SOT23-6L package protecting two independent twisted pairs with shared ground reference. Use Value: Pin-compatible dual-channel layout reduces PCB area by 40% vs. discrete 2× SOT23-3 devices, lowering BOM count and assembly cost. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J24A | Unidirectional, 24 V VBR, 100 W peak power, 150 pF capacitance | Requires external polarity management; unsuitable for AC-coupled DSL signals without redesign. | Select only if circuit uses DC-biased lines and board space allows larger SMA package. |
| SP1003-024 | 0.35 pF capacitance, 24 V VRM, 50 V VCL @ 12 A, SOT23-6L | Lower clamping voltage but reduced surge rating; validated for IEC 61000-4-2/4-5 only (no GR-1089/K21). | Prefer for ESD-only environments; avoid in telco-coordinated surge systems requiring GR-1089 compliance. |
Compared with SMA6J24A and SP1003-024, DSL03-024SC6 uniquely delivers telecom-grade bidirectional clamping, sub-1 pF capacitance, and GR-1089 validation in SOT23-6L-enabling drop-in protection for VDSL2 modems without compromising signal integrity or regulatory compliance.

FAQ
What is the maximum operating temperature for DSL03-024SC6?
The DSL03-024SC6 has an operating junction temperature range of –40 °C to +125 °C, verified per Table 1 in DocID022325 Rev 2. Its peak pulse power capability remains stable up to Tj = 125 °C, making it suitable for enclosed DSL modems without active cooling.
Does DSL03-024SC6 require external biasing or control signals?
No. DSL03-024SC6 is a passive, bidirectional TVS diode array with no pins for bias, enable, or configuration. It operates automatically during overvoltage events and draws only 0.2 µA leakage at 25 °C under normal conditions.
Can DSL03-024SC6 protect both tip and ring conductors simultaneously?
Yes. Its SOT23-6L pinout supports dual-channel protection: Pins 1/3 protect one conductor pair (e.g., tip), while Pins 4/6 protect the second (e.g., ring), sharing Pins 2 and 5 as low-inductance ground connections per Figure 1 and marking layout in DocID022325 Rev 2.
Is DSL03-024SC6 compatible with lead-free reflow profiles?
Yes. The device uses a lead-free, RoHS-compliant SOT23-6L package rated for maximum soldering temperature of 260 °C for 10 seconds, fully compatible with standard JEDEC J-STD-020D.3 reflow profiles for Pb-free assembly.
