Product details
Overview
D30V0S1UG3LP20-7 from Diodes Incorporated is a single-channel unidirectional TVS diode designed for high-surge transient voltage suppression on power rails and I/O lines. It delivers 30.5V minimum breakdown voltage, 180A peak pulse current (8/20µs), 31V typical clamping voltage at 180A, <1µA reverse leakage at 30V, and 500pF capacitance at 0V - enabling robust ESD/surge protection in space-constrained mobile power interfaces.
For engineers reviewing the D30V0S1UG3LP20-7 datasheet, D30V0S1UG3LP20-7 pinout, D30V0S1UG3LP20-7 application, or D30V0S1UG3LP20-7 equivalent, key selection criteria include clamping voltage under 180A surge, IEC 61000-4-2 ±30kV contact/air ESD rating, U-DFN2020-3 footprint compatibility, and low-profile (0.60mm) mounting for battery rail and USB VBUS protection.
Technical Context
This TVS operates as a unidirectional clamp between anode (Pin 1/2) and cathode (Pin 3), triggering at ≥30.5V to shunt transients to ground. Its low clamping voltage (31V @ 180A) ensures downstream ICs remain within safe operating voltage during lightning-surge events per IEC 61000-4-5.
The device uses silicon avalanche junction technology with NiPdAu-plated copper leadframe and green molding compound (UL 94V-0). Its 500pF junction capacitance at 0V and 135pF at 30V supports high-speed data line compatibility while maintaining effective power-rail clamping.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | DO-214AC package; 33.3V VBR(min); 38.7V VCL @ 100A; 1000pF capacitance | Larger footprint (4.5×2.7mm) and higher clamping voltage - suitable for non-portable industrial power supplies | Select when board space is unconstrained and higher clamping voltage is acceptable for legacy 3.3V/5V rail protection |
| SP1003-030 | SOD-323 package; 30V VRWM; 48V VCL @ 12A; 15pF capacitance | Lower surge rating (12A IPP) and higher clamping - optimized for high-speed data lines, not power rails | Prefer for USB data lines or HDMI where low capacitance is critical; avoid for VBUS or battery protection due to insufficient IPP |
Compared with SMAJ30A and SP1003-030, D30V0S1UG3LP20-7 uniquely balances ultra-compact size, 180A surge capability, and 31V clamping - making it optimal for modern portable power rail protection where space, energy handling, and voltage margin are simultaneously constrained.

FAQ
What is the recommended PCB layout for D30V0S1UG3LP20-7 to achieve rated 180A surge performance?
Use Diodes' published U-DFN2020-3 Type C pad layout: 2.300mm × 1.700mm overall, with 1.100mm × 0.350mm anode pads (Pins 1/2) and 0.400mm × 1.600mm cathode pad (Pin 3). Connect Pin 3 directly to a solid internal ground plane via ≥4 thermal vias (0.3mm diameter, 0.8mm pitch) to maintain clamping voltage under 31V at 180A.
Does D30V0S1UG3LP20-7 support bidirectional transient suppression?
No - D30V0S1UG3LP20-7 is a unidirectional TVS diode. It conducts only when the anode (Pins 1/2) is ≥30.5V positive relative to the cathode (Pin 3). For AC or dual-polarity signal lines, a bidirectional variant like D30V0S1BG3LP20-7 (same package, symmetrical VBR) must be used.
How does the 500pF capacitance affect USB 2.0 VBUS line performance?
At 0V bias, 500pF has negligible impact on USB 2.0 VBUS since it's a DC power line; the critical parameter is 135pF at 30V reverse bias, which introduces <0.1Ω impedance at 480MHz - well below USB 2.0 eye diagram degradation thresholds. Layout separation from D+/D− traces remains essential.
Is D30V0S1UG3LP20-7 qualified for automotive applications per AEC-Q101?
No - this part is not AEC-Q101 qualified. Diodes offers automotive-grade equivalents such as D30V0S1UG3LP20Q-7 (with PPAP documentation and IATF 16949 manufacturing), but D30V0S1UG3LP20-7 is intended for commercial portable electronics per its datasheet scope and qualification records.
