Product details
Overview
D7V0M1U2S9-7 from Diodes Incorporated is a unidirectional surface-mount TVS diode designed for ESD protection of high-speed data lines in portable electronics. It features a 7.5V breakdown voltage (VBR), 7A peak pulse current (IPP), 45pF typical input capacitance (CIN), and meets IEC 61000-4-2 ±30kV air/contact discharge. It is used in USB, audio, and SIM card interfaces of smartphones and digital cameras.
For engineers reviewing the D7V0M1U2S9-7 datasheet, D7V0M1U2S9-7 pinout, D7V0M1U2S9-7 application, or D7V0M1U2S9-7 equivalent, key selection criteria include clamping voltage (13V at 7A), low leakage (<1.0μA at 7V), SOD923 package footprint, thermal resistance (500°C/W), and RoHS/"Green" compliance status.
Technical Context
This TVS operates as a single-channel unidirectional clamp, triggered when reverse voltage exceeds 7.5V (VBR). Its 13V clamping voltage at 7A ensures safe transient suppression for 3.3V/5V signal lines without disrupting normal operation.
The device uses a planar silicon junction structure optimized for low capacitance (45pF at 0V) and fast response to ESD events. Its SOD923 package supports high-density PCB layouts while maintaining thermal performance up to +150°C junction temperature.
Key Specifications

| VBR (Min) | 7.5 V - Ensures reliable triggering above 3.3V/5V rail voltages without false activation |
| IPP (Max) | 7 A - Withstands 8/20μs surge pulses per IEC 61000-4-2 Level 4 |
| VCL @ 7A | 13 V - Limits transient voltage to safe level for downstream ICs with 3.3V I/O tolerance |
| CIN (Typ) | 45 pF - Minimizes signal distortion on USB 2.0 and audio paths up to 48MHz |
| IR @ 7V | ≤1.0 μA - Prevents measurable DC loading on high-impedance sensor or RF bias lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | DO-214AC package (4.5mm × 3.9mm); 100W PPP; 10.5V VCL @ 10A | Higher power, larger footprint - suitable for industrial I/O, not portable PCBs | Select for higher surge margin where board space permits |
| ESD5Z7.0 | SOD-523 package; 5.5V VBR; 30pF CIN; 12V VCL @ 5A | Lower capacitance but reduced clamping margin - better for RF front-end, less robust for USB | Select when sub-30pF is mandatory and 7A surge is not required |
Compared with SMAJ7.0A and ESD5Z7.0, D7V0M1U2S9-7 uniquely balances 45pF capacitance, 7.5V VBR, and SOD923 size-making it optimal for consumer USB/audio interfaces where density and ESD immunity must coexist.

FAQ
What is the maximum clamping voltage of D7V0M1U2S9-7 under standard test conditions?
The maximum clamping voltage (VCL) is 13 V when subjected to a 7 A, 8/20 μs transient pulse. This value is measured at the device terminals with specified PCB layout per AP02001, ensuring consistent performance across production boards and eliminating ambiguity in system-level surge testing.
Is D7V0M1U2S9-7 suitable for bidirectional signal lines like USB D+/D−?
No - D7V0M1U2S9-7 is unidirectional and must be oriented with cathode to ground. For bidirectional protection on differential lines, two devices are required (one per line) or a dedicated bidirectional TVS such as D5V0F1U2S9-7 should be selected instead.
Does the SOD923 package support automated optical inspection (AOI) after reflow?
Yes - the SOD923's defined top-view marking "TF" (pin 1/cathode indicator), uniform matte tin finish, and controlled coplanarity (0.10 mm max) enable reliable AOI detection of solder joint quality and orientation on high-speed SMT lines.
How does the 45 pF input capacitance affect USB 2.0 signal integrity?
At 480 Mbps, 45 pF introduces <1% rise-time degradation on standard 90Ω differential traces when placed within 3 mm of the connector. Measured eye diagrams show >30% eye height margin, confirming compatibility without equalization or layout compensation.
