Product details
Overview
D24V0S1U2T-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, 27 V minimum breakdown voltage, 35 pF typical junction capacitance, 6 A peak pulse current (8/20 µs), and ±15 kV IEC 61000-4-2 contact/air ESD rating - deployed in USB modules, HDMI ports, and LVDS interfaces.
For engineers reviewing the D24V0S1U2T-7 datasheet, D24V0S1U2T-7 pinout, D24V0S1U2T-7 application, or D24V0S1U2T-7 equivalent, this device delivers low-capacitance transient suppression with automotive-grade reliability (Q-grade variant available), SOD523 footprint compatibility, and verified clamping performance at 36 V (1 A) and 60 V (6 A).
Technical Context
This TVS operates as a unidirectional clamp between signal line and ground, triggering above 27 V to shunt ESD transients while maintaining <200 nA leakage at 24 V. Its 35 pF capacitance ensures minimal signal integrity impact on 480 Mbps USB 2.0 and 1.65–6 Gbps HDMI 1.4/2.0 channels.
The device uses silicon avalanche structure optimized for fast response (<1 ns), with thermal resistance of 500 °C/W and power derating to 250 mW at +25°C ambient. It meets JEDEC J-STD-020 Level 1 moisture sensitivity and UL 94V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Maximum continuous operating voltage before conduction begins; sets upper limit for protected signal swing. |
| Breakdown Voltage (VBR) | 27 V (min) - Avalanche onset threshold; ensures reliable turn-on before downstream IC damage occurs. |
| Clamping Voltage (IPP = 6 A) | 60 V - Peak voltage seen by protected circuit during worst-case 8/20 µs surge; defines safe margin vs. IC abs max rating. |
| Junction Capacitance | 35 pF (typ @ 0 V, 1 MHz) - Low enough to avoid signal distortion on USB 2.0 and HDMI 1.4 differential pairs. |
| ESD Rating | ±15 kV (contact/air, IEC 61000-4-2) - Full system-level ESD immunity without external shielding or layout reinforcement. |
| Peak Pulse Power | 360 W (8/20 µs) - Sustains multiple ESD events without degradation under standard test waveform. |
| Leakage Current | 200 nA (max @ 24 V) - Negligible loading on high-impedance data receivers; avoids DC bias shift. |
Pinout & Package
Package: SOD523 - ultra-compact surface-mount package (1.25 mm × 0.85 mm × 0.65 mm), matte tin-plated copper leadframe, halogen/antimony-free green molding compound (UL 94V-0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode) | Anode-to-ground connection point | Connected to protected signal line; cathode tied to system ground to enable unidirectional clamping. |
| Pin 2 (Anode) | Ground reference terminal | Direct low-inductance path to PCB ground plane; critical for sub-nanosecond ESD response time. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD Protection | ±15 kV contact/air - Eliminates need for secondary board-level ESD filters in portable designs. |
| Low Input Capacitance | 35 pF - Preserves signal rise/fall times on 480 Mbps USB 2.0 and 1.65 Gbps HDMI 1.4 links. |
| SOD523 Footprint | 1.25 × 0.85 mm - Enables placement directly at connector entry points without routing detours. |
| Lead-Free & Green Compliance | RoHS 3 / Halogen-free (<900 ppm Br+Cl, <1000 ppm Sb) - Meets global environmental mandates without performance trade-offs. |
Applications
| USB 2.0 Interface Protection | HDMI 1.4 Differential Pair Protection |
|---|---|

IC Role / Device Role / Timing Role: Point-of-entry protection on twisted-pair inputs, grounded via shortest possible trace. Use Value: Delivers 6 A surge handling with 27 V VBR to protect 3.3 V/5 V transceivers without false triggering during normal operation. |
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 × 2.7 mm); 3.5 pF higher capacitance (38.5 pF); 100 W lower PPP (260 W) | Not suitable for space-constrained USB/HDMI layouts; better for industrial PCBs with larger keepouts | Select when board area allows larger footprint and higher clamping voltage (64 V @ 6 A) is acceptable |
| SP1003-02JT | SOD-323 package (1.7 × 1.25 mm); 15 pF lower capacitance (20 pF); 1.5× higher leakage (300 nA @ 24 V) | Better for RF-sensitive analog sensor lines but less robust for high-current ESD events (IPP = 4 A) | Prefer for low-noise analog front-ends where <25 pF is mandatory and peak surge is ≤4 A |
Compared with SMAJ24A and SP1003-02JT, D24V0S1U2T-7 uniquely balances ultra-small SOD523 size, 35 pF capacitance, and 6 A surge capability - making it optimal for next-gen portable interface protection where board space and signal fidelity are both constrained.

FAQ
What is the maximum clamping voltage of D24V0S1U2T-7 at 6 A surge current?
The clamping voltage is 60 V under 8/20 µs waveform conditions at 6 A peak pulse current, as specified in the Electrical Characteristics table. This value represents the maximum voltage imposed on the protected line during worst-case ESD event, ensuring compatibility with 3.3 V and 5 V interface ICs rated for ≤65 V absolute maximum.
Can D24V0S1U2T-7 be used for bidirectional signal lines like USB D+/D−?
No - D24V0S1U2T-7 is unidirectional and must be oriented with cathode toward the signal line and anode to ground. For bidirectional protection, two devices are required per differential pair (one per line), or a dedicated bidirectional TVS such as D24V0L1U2T-7 should be selected instead.
Is the SOD523 package compatible with standard reflow profiles?
Yes - the SOD523 package is qualified for IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard lead-free reflow profiles (peak temperature ≤260°C). Its 0.001 g mass and low thermal mass enable uniform heating without tombstoning on fine-pitch layouts.
Does D24V0S1U2T-7 meet automotive qualification standards?
The base D24V0S1U2T-7 is not AEC-Q200 qualified; however, the automotive-compliant variant D24V0S1U2TQ is available under a separate datasheet and meets AEC-Q200 Grade 2 (-40°C to +105°C) requirements with enhanced process controls and extended testing.
