Product details
Overview
D24V0S1UG3LP20-7 from Diodes Incorporated is a single-channel unidirectional TVS diode designed for ESD and surge protection of high-speed data lines and power rails in portable electronics. It features a 24 V reverse working voltage (VRWM), 25.0 V minimum breakdown voltage (VBR), 27.1 V typical clamping voltage at 160 A, 630 pF capacitance at 0 V, and IEC 61000-4-2 ±30 kV contact/air ESD rating - deployed in cellular handsets and USB interfaces.
For engineers reviewing the D24V0S1UG3LP20-7 datasheet, D24V0S1UG3LP20-7 pinout, D24V0S1UG3LP20-7 application, or D24V0S1UG3LP20-7 equivalent, key selection criteria include clamping performance under 200 A 8/20 µs surge, low-profile U-DFN2020-3 packaging, VRWM alignment with 24 V supply rails, and IEC-compliant ESD robustness for compact consumer interfaces.
Technical Context
This TVS diode operates as a unidirectional transient suppressor, with cathode-anode configuration enabling clamping only during negative transients relative to ground. Its low 0.60 mm profile and 2.3 mm × 1.7 mm footprint support space-constrained PCB layouts in handheld devices.
The device delivers 5680 W peak pulse power (8/20 µs) and maintains sub-30 V clamping up to 200 A, while exhibiting 630 pF capacitance at 0 V - a trade-off optimized for ESD/surge co-protection on moderate-speed signal lines such as USB 2.0 or audio jack inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V - Maximum continuous reverse operating voltage before leakage exceeds 0.5 µA; matches standard 24 V DC rail systems. |
| VBR (min) | 25.0 V at 1 mA - Ensures reliable turn-on above normal operating voltage to avoid false triggering. |
| VCL @ 160 A | 27.1 V typ - Clamping voltage during 8/20 µs surge; limits downstream IC stress below 30 V threshold. |
| IPP (max) | 200 A - Peak surge current handling per IEC 61000-4-5 Level 4; supports lightning-induced line surges. |
| Capacitance | 630 pF @ 0 V - Impacts signal integrity on data lines; suitable for ≤480 Mbps USB 2.0 but not USB 3.0. |
| ESD Rating | ±30 kV air/contact per IEC 61000-4-2 - Full system-level ESD immunity without external shielding. |
Pinout & Package
Package: U-DFN2020-3 (Type C), 2.0 mm × 2.0 mm body, 0.60 mm height, 3-terminal leadless package with exposed thermal pad (Pin 1 and Pin 2 electrically connected internally).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected signal/power line; forms cathode-to-ground clamping path when transient exceeds VBR. |
| Pin 2 | Anode (tie) | Internally bonded to Pin 1; requires PCB copper connection for mechanical stability and thermal conduction. |
| Pin 3 | Cathode | Connected to system ground; provides low-impedance return path for surge current during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.60 mm max height - enables integration beneath thin bezels and stacked flex PCB assemblies. |
| IEC 61000-4-2 compliance | ±30 kV contact/air - eliminates need for secondary ESD components in end-product certification testing. |
| Lead-free & halogen-free | RoHS 3 / "Green" compliant (<900 ppm Br+Cl, <1000 ppm Sb) - meets global environmental compliance mandates without derating. |
| Thermal resistance | RθJA = 250 °C/W - enables sustained 500 mW operation on standard FR-4 with recommended pad layout. |
Applications
| USB 2.0 Data Line Protection | 24 V DC Power Rail Clamp |
|---|---|
Use Scenario: Protecting D+/D− lines in smartphone USB ports against ESD events during cable insertion and hot-plug. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between data line and ground, triggered only on negative transients relative to VCC. Use Value: Maintains 630 pF capacitance to preserve signal rise/fall times while clamping to ≤27.1 V at 160 A - preventing PHY layer damage without signal distortion. | Use Scenario: Safeguarding 24 V input rails in industrial handheld scanners against load-dump and inductive switching surges. IC Role / Device Role / Timing Role: Standoff protector across power rail and chassis ground, absorbing 5680 W 8/20 µs pulses without failure. Use Value: Withstands 200 A peak surge and holds clamping voltage below 30 V - ensuring downstream regulators and microcontrollers remain within absolute maximum ratings. |
| Audio Jack ESD Suppression | Portable Camera Interface Protection |
Use Scenario: Shielding 3.5 mm TRRS audio jacks in Bluetooth headsets from user-hand ESD discharges. IC Role / Device Role / Timing Role: Low-capacitance TVS on left/right/ground paths, leveraging ±30 kV IEC 61000-4-2 rating for direct human-contact immunity. Use Value: Delivers full ESD protection without adding audible pop or crosstalk due to controlled 630 pF coupling and fast 1 ns response time. | Use Scenario: Securing MIPI CSI-2 camera interface lines in compact action cameras exposed to field ESD and vibration-induced transients. IC Role / Device Role / Timing Role: Single-channel TVS on each data lane, mounted adjacent to connector to minimize inductance and maximize clamping speed. Use Value: 2.3 mm × 1.7 mm footprint allows placement within 2 mm of connector - reducing loop inductance and improving clamping effectiveness by >40% vs. larger packages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | DO-214AC package; 24 V VRWM; 38.9 V VCL @ 10.3 A; 400 W PPP | Larger footprint (4.3 mm × 2.6 mm); higher clamping voltage; lower surge rating | Choose for cost-sensitive industrial designs where board space is available and 200 A surge is not required. |
| SP1003-02HTG | SOD-323 package; 24 V VRWM; 33.6 V VCL @ 1 A; 300 W PPP; 150 pF @ 0 V | Lower capacitance but significantly reduced surge capability (30 A IPP); no 200 A rating | Prefer for high-speed signal lines (e.g., HDMI) where <200 pF is mandatory, accepting lower surge margin. |
Compared with SMAJ24A and SP1003-02HTG, D24V0S1UG3LP20-7 uniquely balances ultra-compact size, 200 A surge handling, and sub-30 V clamping - making it optimal for next-gen portable devices requiring both ESD and lightning-level protection in minimal area.

FAQ
What is the polarity configuration of D24V0S1UG3LP20-7?
D24V0S1UG3LP20-7 is a unidirectional TVS diode with anode (Pins 1 & 2) and cathode (Pin 3). It clamps only negative transients relative to ground - ideal for protecting positive-rail signals like USB D+ or 24 V power lines. Its VBR of 25.0 V ensures no conduction during normal 24 V operation.
Can this TVS be used on bidirectional signal lines like RS-485?
No - D24V0S1UG3LP20-7 is unidirectional and unsuitable for true bidirectional lines without additional circuitry. For RS-485, a bidirectional TVS such as D24V0L1UP3LP20 (same package, symmetrical clamping) is required to protect both positive and negative transients on differential pairs.
How does its 630 pF capacitance affect USB 2.0 signal integrity?
At 630 pF, the device introduces ~0.5 dB insertion loss at 480 MHz but preserves eye diagram margins for USB 2.0 (480 Mbps) when placed close to the connector. Layout best practices - including minimized trace length and ground plane continuity - ensure jitter remains within USB specification limits.
Is D24V0S1UG3LP20-7 qualified for automotive use?
No - this part is not AEC-Q200 qualified. While Diodes offers automotive-grade variants (e.g., D24V0S1UG3LP20Q-7), the standard -7 suffix indicates commercial temperature range (-55°C to +150°C) and non-PPAP packaging; automotive deployment requires explicit qualification documentation and change control.
