Product details
Overview
DA473S6-TL-H from SANYO Semiconductor is a quad-channel ESD protection diode array designed for high-speed data line protection in portable electronics. It features 6.0 V reverse voltage rating, ≤1 μA reverse current at 5 V, 30 pF interterminal capacitance at 0 V/1 MHz, 18 kV contact discharge ESD immunity per IEC61000-4-2, and operates within -55°C to +150°C storage range. It protects USB 2.0, HDMI, and audio interface lines.
For engineers reviewing the DA473S6-TL-H datasheet, pinout, applications, or equivalent options, key selection criteria include channel count (4), ground pin configuration (dual GND), low capacitance for signal integrity, guaranteed ESD robustness, and halogen-free compliance for RoHS-constrained designs.
Technical Context
This device integrates four independent silicon diffused junction diodes in a single 6-pin SC-6 package. Each channel provides bidirectional clamping between signal line and ground, with specified reverse breakdown at 6.0–7.7 V and sub-1 μA leakage at 5 V bias.
The dual-GND pin arrangement (pins 2 and 5) enables low-inductance return paths for all four channels, supporting simultaneous transient suppression across multiple high-speed lines without crosstalk degradation. Interterminal capacitance remains stable at 30 pF (0 V, 1 MHz), verified per test condition in A1377-2/4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 6.0 V min - Ensures reliable clamping onset before damage to 3.3 V or 5 V logic interfaces. |
| Reverse Current (IR) | ≤1 μA at VR = 5 V - Minimizes standby power loss and signal loading on protected lines. |
| Interterminal Capacitance (C) | 30 pF at VR = 0 V, f = 1 MHz - Preserves signal integrity for USB 2.0 (480 Mbps) and audio differential pairs. |
| ESD Withstand (Contact) | 18 kV per IEC61000-4-2 - Meets industrial-grade immunity requirements without external TVS staging. |
| Junction Temperature (Tj) | 150 °C max - Supports operation in thermally constrained handheld enclosures with minimal derating. |
| Package | SC-6 (SCH6) - 1.6 × 1.6 mm footprint with 0.5 mm pitch, enabling dense layout on compact PCBs. |
Pinout & Package
DA473S6-TL-H uses the SC-6 (SANYO SCH6) surface-mount package: 1.6 mm × 1.6 mm body, 0.5 mm lead pitch, 0.25 mm nominal thickness. Pin 1 (IN1) to Pin 6 (IN4) are arranged in a single row with dual ground terminals (Pins 2 and 5) for low-impedance ESD return path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN1 | Input terminal for first ESD-protected signal line (e.g., USB D+). |
| 2 | GND | Dedicated ground return for channels 1 and 2; minimizes shared impedance during transient events. |
| 3 | IN2 | Input terminal for second protected line (e.g., USB D−). |
| 4 | IN3 | Input terminal for third protected line (e.g., HDMI TMDS0+). |
| 5 | GND | Dedicated ground return for channels 3 and 4; isolates return currents from pins 2 and 3. |
| 6 | IN4 | Input terminal for fourth protected line (e.g., HDMI TMDS0−). |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel integration | Four independent ESD diodes in one SC-6 package reduce board area vs. discrete solutions by >60%. |
| 18 kV contact ESD rating | Guaranteed per IEC61000-4-2 - eliminates need for secondary protection in consumer-grade USB/HDMI ports. |
| Dual-GND architecture | Pins 2 and 5 provide separate low-inductance ground returns for two channel pairs, limiting crosstalk under multi-line transients. |
| Halogen-free construction | Complies with JIS C0950 and IEC 61249-2-21 - supports green manufacturing and end-of-life recycling mandates. |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 host/device ports against electrostatic discharge in smartphones and tablets. IC Role / Device Role / Timing Role: Bidirectional ESD clamp placed directly at connector, shunting transients to ground before reaching PHY IC. Use Value: 30 pF capacitance ensures <1% signal distortion at 480 Mbps; dual-GND pins prevent ground bounce coupling between D+ and D−. | Use Scenario: Safeguarding TMDS clock and data pairs in HDMI source/sink devices against handling-induced ESD. IC Role / Device Role / Timing Role: Low-capacitance transient voltage suppressor mounted adjacent to HDMI receptacle, clamping spikes to <12 V. Use Value: 6.0 V VR rating aligns with HDMI common-mode voltage range; 18 kV immunity exceeds IEC 61000-4-2 Level 4 requirement. |
| Mobile Audio Jack Protection | Industrial Control Panel Keypad Lines |
Use Scenario: Shielding stereo headphone/mic TRRS lines in portable media players from user-handling ESD. IC Role / Device Role / Timing Role: Four-channel array protecting left/right audio, mic, and ground-sense lines simultaneously. Use Value: Quad integration avoids mismatched clamping thresholds; 1 μA IR prevents DC offset in analog audio paths. | Use Scenario: Hardening membrane keypad scan lines in factory HMIs exposed to frequent operator contact. IC Role / Device Role / Timing Role: ESD guard for 4-key matrix rows/columns, connected to microcontroller GPIOs with weak pull-ups. Use Value: 150°C Tstg rating supports operation near heat-generating PLC modules; halogen-free material meets industrial flame-retardancy standards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DRYR | Single-channel, 0.5 pF typical capacitance, 12 kV IEC61000-4-2 contact rating. | Requires four discrete units for quad-line coverage; lower capacitance suits USB 3.0 but higher BOM cost and layout area. | Prefer when ultra-low capacitance (<1 pF) is mandatory and board space allows discrete placement. |
| ESD5V3U2U-2/TR | Quad-channel, 5.3 V VR, 12 kV contact rating, SC-70-6 package (2.0 × 1.25 mm). | Larger footprint than DA473S6-TL-H; higher leakage (5 μA at 5 V) may affect high-impedance sensor lines. | Select when 5.3 V clamping threshold better matches 3.3 V rail tolerance, and SC-70-6 is already standardized in design. |
Compared with TPD4E001DRYR and ESD5V3U2U-2/TR, DA473S6-TL-H delivers superior ESD robustness (18 kV vs. ≤12 kV) in the smallest footprint (1.6 × 1.6 mm), while maintaining 30 pF capacitance optimized for USB 2.0 and HDMI - making it optimal for space-constrained consumer port protection where peak immunity matters most.

The DA473S6-TL-H has a maximum junction temperature (Tj) rating of 150°C and a storage temperature range of –55°C to +150°C. It is rated for continuous operation in ambient environments up to 85°C when mounted on standard FR-4 PCBs with typical thermal relief. Derating is recommended above 70°C ambient if power dissipation exceeds 5 mW per channel.
Does DA473S6-TL-H support bidirectional ESD protection?
Yes, DA473S6-TL-H provides bidirectional clamping for each of its four channels. Each diode pair is configured as a back-to-back arrangement between signal and ground, enabling symmetrical suppression of both positive and negative ESD transients per IEC61000-4-2 contact discharge testing.
What is the marking code for DA473S6-TL-H?
The top-side marking for DA473S6-TL-H is "4A", as confirmed in the SANYO datasheet No. A1377-1/4. This 2-character code identifies the device variant and is laser-etched on the SC-6 package body for traceability and visual verification during assembly and inspection.
Can DA473S6-TL-H be used for HDMI 1.4 differential pairs?
Yes, DA473S6-TL-H is suitable for HDMI 1.4 TMDS differential pairs. Its 30 pF interterminal capacitance at 0 V/1 MHz introduces negligible skew or attenuation at 165 MHz pixel clock rates, and its 18 kV ESD rating exceeds HDMI compliance requirements. Pins 4 and 6 protect one differential pair, while pins 1 and 3 protect another - using dual GND pins (2 and 5) for clean return paths.
Is DA473S6-TL-H halogen-free and RoHS compliant?
Yes, DA473S6-TL-H is explicitly stated as halogen-free per JIS C0950 and IEC 61249-2-21 in the SANYO datasheet.
