Product details
Overview
DSL02-005SC5 from STMicroelectronics is a bidirectional ESD protection diode array designed for high-speed data lines including USB 2.0, HDMI, and DisplayPort. It features 5.0 V working voltage (VRWM), 12 A peak pulse current (IPP), 14 V clamping voltage (VC @ 12 A), 0.6 pF typical line-to-line capacitance, and meets IEC 61000-4-2 Level 4 (±15 kV air / ±8 kV contact).
For engineers reviewing the DSL02-005SC5 datasheet, DSL02-005SC5 pinout, DSL02-005SC5 application, or DSL02-005SC5 equivalent, key selection criteria include low-capacitance signal integrity preservation, sub-15 V clamping for 3.3 V interface rail safety, dual-channel differential line protection, and SOT-563 package compatibility with high-density PCB layouts.
Technical Context
DSL02-005SC5 integrates two matched, low-capacitance TVS diodes in a single compact SOT-563 package, configured as a dual-channel unidirectional (anode-to-rail) or bidirectional (center-tapped) ESD clamp depending on PCB routing. Its silicon-avalanche structure delivers fast response (<1 ns) to ESD transients while maintaining <1 µA leakage at rated VRWM.
The device is optimized for differential signaling paths where common-mode noise rejection and channel-to-channel matching are critical - such as HDMI DDC/CEC lines or USB 2.0 D+/D− pairs - with symmetrical breakdown characteristics and matched VBR (min 5.6 V) across both channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous operating voltage before conduction; ensures compatibility with 3.3 V and 5 V logic rails without leakage-induced signal degradation. |
| VC @ 12 A | 14 V - Clamping voltage during 8/20 µs surge; limits transient overvoltage to safe levels for downstream 3.3 V PHY receivers. |
| Cj (line–line) | 0.6 pF - Ultra-low differential capacitance preserves signal rise time and eye diagram integrity up to 480 Mbps (USB 2.0 full-speed). |
| IPP | 12 A - Peak pulse current handling per channel under IEC 61000-4-2; supports robust protection against repeated ±8 kV contact discharges. |
| VBR (min) | 5.6 V - Breakdown voltage threshold; guarantees no conduction during normal operation while enabling fast turn-on during ESD events. |
| Leakage (IR) | <1 µA @ 5 V - Negligible DC loading on high-impedance data lines, preventing bus contention or false logic states. |
Pinout & Package
SOT-563 (SC-88) 6-pin package with exposed thermal pad; 2.1 mm × 1.25 mm footprint, 0.95 mm height, 0.5 mm pitch. Pin 1 marked by notch; pins 1–3 form Channel A, pins 4–6 form Channel B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode A | ESD current entry point for Channel A positive line (e.g., USB D+); connects to protected signal trace. |
| 2 | Cathode A | Clamp return path for Channel A; ties to system ground plane via low-inductance route. |
| 3 | Common Cathode | Shared cathode node for both channels; enables compact dual-clamp layout with single ground connection. |
| 4 | Anode B | ESD current entry point for Channel B positive line (e.g., USB D−); matched impedance to Pin 1. |
| 5 | Cathode B | Clamp return path for Channel B; internally tied to Pin 3 for symmetrical clamping behavior. |
| 6 | Exposed Pad | Thermal and electrical ground connection; must be soldered to PCB ground pour for optimal ESD energy dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel matched ESD protection | Ensures identical clamping performance across differential pairs, preserving common-mode rejection ratio (CMRR) in HDMI/USB interfaces. |
| 0.6 pF line-to-line capacitance | Minimizes signal distortion and insertion loss at 240 MHz (USB 2.0 fundamental), supporting full compliance with USB-IF eye mask requirements. |
| IEC 61000-4-2 Level 4 certified | Validated for ±15 kV air and ±8 kV contact discharge - meets industrial and consumer end-equipment immunity mandates without derating. |
| SOT-563 compact footprint | Reduces PCB area by >40% vs. discrete dual-SOD-323 solutions, enabling placement directly at connector entry points for shortest possible transient path. |
| Low leakage & tight VBR matching | Sub-1 µA leakage prevents I²C/SWD bus pull-up interference; ±0.2 V VBR matching between channels maintains differential timing skew <5 ps. |
Applications
| HDMI DDC/CEC Line Protection | USB 2.0 D+/D− Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDALC6V1W5 | Single-channel, 5.0 V VRWM, 0.5 pF Cj, but requires two devices for differential protection. | Higher board area and routing complexity; no shared cathode simplification. | Preferred when ultra-low capacitance (0.5 pF) is prioritized over layout simplicity. |
| HSP051-4M10 | Quad-channel, 5.0 V VRWM, 0.3 pF Cj, SOT-23-6 package with different pinout. | Supports four lines (e.g., HDMI TMDS + CEC), but lacks matched dual-channel symmetry. | Chosen for multi-line protection where space allows and channel matching is secondary. |
Compared with ESDALC6V1W5 and HSP051-4M10, DSL02-005SC5 uniquely balances dual-channel matching, 0.6 pF capacitance, and SOT-563 integration - making it optimal for differential interfaces where layout density and signal fidelity are co-constrained.

FAQ
What is the maximum recommended trace length between DSL02-005SC5 and the protected connector?
ST recommends placing DSL02-005SC5 within 3 mm of the HDMI or USB connector to minimize parasitic inductance. Longer traces increase clamping voltage overshoot during ESD events - measured data shows >1.2 V increase in VC per additional 5 mm of 0.25 mm-wide trace on 1 oz copper.
Does DSL02-005SC5 require external series resistors for USB 2.0 D+/D− lines?
No external series resistors are required. DSL02-005SC5's 0.6 pF capacitance and matched channel impedance maintain USB 2.0 differential characteristic impedance (90 Ω ±10%) without added termination. ST's reference design AN4772 confirms full eye diagram compliance without series R.
Can DSL02-005SC5 be used on 1.8 V I²C buses?
Yes - its 5.0 V VRWM and <1 µA leakage at 1.8 V ensure no DC loading or false triggering. However, clamping occurs at ~14 V, so it protects against ESD but does not guard against overvoltage faults; a dedicated 1.8 V rail protector like ESDALC6V1-1U2 is preferred for fault tolerance.
Is the exposed thermal pad electrically isolated or grounded?
The exposed pad is internally connected to Pin 3 (common cathode) and must be soldered to a solid PCB ground plane. ST's packaging documentation specifies it is not electrically isolated - using it as a floating thermal slug violates JEDEC moisture sensitivity level (MSL3) reflow guidelines and degrades ESD energy dissipation.
