Product details
Overview
D24V0S1U2TQ-7 from Diodes Incorporated is a single-channel unidirectional TVS diode designed for ESD protection of high-speed data lines. It features a 24 V reverse standoff voltage, 36 V clamping voltage at 1 A, 35 pF typical junction capacitance, ±30 kV IEC 61000-4-2 contact/air ESD rating, and SOD523 package-ideal for USB 2.0 and HDMI port protection in portable consumer electronics.
For engineers reviewing the D24V0S1U2TQ-7 datasheet, D24V0S1U2TQ-7 pinout, D24V0S1U2TQ-7 application, or D24V0S1U2TQ-7 equivalent, key selection criteria include low-capacitance transient suppression, automotive-grade AEC-Q101 qualification, IATF 16949 manufacturing compliance, and precise 2-pin SOD523 terminal mapping for layout-sensitive high-frequency interfaces.
Technical Context
This TVS operates as a unidirectional clamp between signal line and ground, triggering at ≥27 V breakdown (1 mA) to divert ESD transients while maintaining <200 nA leakage at 24 V. Its 35 pF capacitance enables use on 480 Mbps USB 2.0 lines without signal integrity degradation.
The device meets IEC 61000-4-2 Level 4 (±30 kV air/contact) and IEC 61000-4-5 surge immunity (36 V clamping at 1 A, 8/20 µs), with thermal derating to 250 mW at +25°C and RθJA = 500°C/W on standard FR-4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Maximum continuous working voltage before clamping begins |
| Breakdown Voltage (VBR) | 27–34 V @ 1 mA - Ensures reliable turn-on above normal signal swing |
| Clamping Voltage (VCL) | 36 V @ 1 A, 8/20 µs - Limits transient voltage seen by protected IC input |
| Junction Capacitance | 35 pF @ 0 V, 1 MHz - Low enough for USB 2.0 (480 Mbps) and HDMI 1.4 signal integrity |
| ESD Rating | ±30 kV contact & air per IEC 61000-4-2 - Full Level 4 system-level ESD robustness |
| Peak Pulse Power | 360 W @ 8/20 µs - Handles high-energy transients without failure |
| Leakage Current | 200 nA @ 24 V - Negligible DC loading on high-impedance data lines |
Pinout & Package
Package: SOD523 - ultra-compact surface-mount plastic case (1.2 mm × 0.8 mm × 0.6 mm), moisture sensitivity level 1, matte tin-plated copper leadframe, UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode) | Anode connection to protected signal line | Connected to high-speed data line (e.g., USB D+, HDMI TMDS+); polarity defines unidirectional clamping path |
| Pin 2 (Anode) | Cathode connection to ground reference | Direct low-inductance tie to system ground plane; critical for effective ESD current shunting |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive infotainment and ADAS interface protection under temperature cycling, HTRB, and ESD stress |
| IATF 16949 certified manufacturing | Ensures consistent lot-to-lot parametric stability and traceable process control for OEM supply chains |
| 35 pF junction capacitance | Enables placement directly at connector entry point without degrading eye diagram margin on 480 Mbps links |
| ±30 kV IEC 61000-4-2 rating | Eliminates need for secondary board-level ESD filters in handheld and docking station designs |
| Halogen- and antimony-free "Green" construction | Meets IPC-1752A material declaration requirements for RoHS 3 and automotive ELV compliance |
Applications
| USB 2.0 Interface Protection | HDMI 1.4 Port Protection |
|---|---|
Use Scenario: Protecting USB 2.0 D+ and D− lines in smartphones, tablets, and OTG adapters against repeated plug/unplug ESD events. IC Role / Device Role / Timing Role: Unidirectional TVS placed between data line and chassis ground to clamp fast-rising ESD pulses before they reach the USB transceiver PHY. Use Value: 35 pF capacitance preserves signal rise/fall times; ±30 kV rating ensures >10,000 insertion cycles without performance degradation. | Use Scenario: Safeguarding HDMI 1.4 TMDS differential pairs in set-top boxes, monitors, and gaming consoles during hot-plug and handling. IC Role / Device Role / Timing Role: One D24V0S1U2TQ-7 per TMDS channel (clock/data) providing low-capacitance, high-surge clamping referenced to shield ground. Use Value: 36 V clamping at 1 A prevents HDMI receiver input overvoltage; SOD523 footprint minimizes trace stub length for 165 MHz pixel clock integrity. |
| Automotive Infotainment Display Link | LVDS Camera Interface Protection |
Use Scenario: ESD hardening of MIPI D-PHY or FPD-Link III video buses connecting head units to digital dash displays. IC Role / Device Role / Timing Role: Unidirectional TVS on each high-speed video lane, mounted adjacent to connector to minimize inductance in discharge path. Use Value: AEC-Q101 qualification guarantees operation from −40°C to +125°C ambient; 24 V standoff matches typical display bus common-mode range. | Use Scenario: Protecting LVDS serial camera links in rear-view and surround-view systems against cable-discharge events. IC Role / Device Role / Timing Role: Bidirectional protection not required-unidirectional clamp suffices since LVDS common-mode stays within 0–2.5 V range. Use Value: 35 pF capacitance avoids skew between differential pairs; 27–34 V VBR avoids false triggering during power-up sequencing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | DO-214AC package (4.5 mm × 2.7 mm), 3.5 pF higher capacitance (38.5 pF), 400 W PPP | Too large for space-constrained USB/HDMI connectors; better suited for board-level primary protection | Select when higher surge rating is needed and layout area permits larger footprint |
| TPD2E001DRYR | 2-channel array in SOT-553, 15 pF per channel, same 24 V standoff, but only ±8 kV ESD rating | Lower ESD robustness limits use to non-critical internal traces-not recommended for external ports | Select only for cost-sensitive internal signal lines where full ±30 kV is not mandated |
Compared with SMAJ24A and TPD2E001DRYR, D24V0S1U2TQ-7 uniquely balances ultra-small SOD523 size, 35 pF capacitance, and full ±30 kV system-level ESD immunity-making it the only choice for compact, high-reliability external interface protection in automotive and premium consumer devices.

FAQ
What is the polarity configuration of D24V0S1U2TQ-7?
D24V0S1U2TQ-7 is a unidirectional TVS diode with cathode (Pin 1) connected to the protected signal line and anode (Pin 2) tied to ground. This configuration provides clamping only for positive transients relative to ground, matching the operating voltage range of USB, HDMI, and LVDS interfaces where negative excursions are limited or absent.
Does D24V0S1U2TQ-7 meet automotive qualification requirements?
Yes-D24V0S1U2TQ-7 is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. It undergoes stress testing including temperature cycling, high-temperature reverse bias, and ESD verification per automotive standards, making it approved for use in infotainment, ADAS camera links, and instrument cluster interfaces.
Can D24V0S1U2TQ-7 be used on bidirectional data lines like RS-485?
No-D24V0S1U2TQ-7 is unidirectional and unsuitable for true bidirectional lines requiring symmetrical clamping. For RS-485 or CAN, a bidirectional TVS such as D24V0L1U2TQ (same package, dual-clamp architecture) must be used to protect both positive and negative transients equally.
What is the maximum recommended PCB trace length between D24V0S1U2TQ-7 and the protected connector?
For optimal ESD performance, the distance from D24V0S1U2TQ-7 anode (Pin 2) to the nearest low-inductance ground via should not exceed 2 mm, and the signal trace from Pin 1 to the connector pad should be ≤3 mm. Longer paths increase inductance, raising clamped voltage during fast ESD events and risking downstream IC damage.
