Product details
Overview
D5V0M1U2S9-7 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 5.5V reverse standoff voltage, 6.2V minimum breakdown voltage, 12V clamping voltage at 9A peak pulse current, 54pF typical input capacitance, and meets IEC 61000-4-2 ±30kV (contact/air) ESD standard. It is used in USB, HDMI, and audio interfaces of smartphones and digital cameras.
For engineers reviewing the D5V0M1U2S9-7 datasheet, D5V0M1U2S9-7 pinout, D5V0M1U2S9-7 application, or D5V0M1U2S9-7 equivalent, key selection criteria include clamping voltage under 12V, sub-60pF capacitance for signal integrity, SOD923 footprint compatibility, unidirectional polarity for DC-biased lines, and compliance with IEC 61000-4-2 Level 4 ESD immunity.
Technical Context
This TVS diode operates as a unidirectional shunt protector, conducting only during positive transients relative to its cathode terminal. Its low 54pF junction capacitance minimizes signal distortion on high-frequency lines up to 500MHz, while the 12V clamping voltage ensures downstream ICs (e.g., USB PHYs rated to 5.5V) remain within safe operating limits during 8/20µs surges.
The device uses an alloy-42 leadframe with matte tin plating and is molded in halogen-free, RoHS-compliant compound rated UL 94V-0. Thermal resistance is 500°C/W on standard FR-4 PCB layout, enabling stable operation from –65°C to +150°C ambient without derating below 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5.5V - Maximum continuous DC voltage before leakage exceeds 1µA; sets upper limit for protected line bias. |
| Breakdown Voltage | 6.2V min @ 1mA - Confirmed avalanche onset; ensures reliable triggering above system operating voltage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package (4.5×2.7mm); 5.0V VRWM; 14.4V clamping @ 9.8A; 150pF capacitance | Higher capacitance limits use to DC/low-speed lines; larger footprint requires PCB redesign | Select when higher surge rating (400W) is needed and board space allows DO-214AC placement. |
| TPD2E001DRYR | 2-channel, bidirectional; 0.9pF per channel; 5.5V VRWM; 12V clamping @ 4A; X2SON-6 package | Lower capacitance suits USB 3.0/MIPI D-PHY; bidirectional operation fits AC-coupled lines | Select for multi-line protection or high-speed differential interfaces where <1pF loading is mandatory. |
Compared with SMAJ5.0A and TPD2E001DRYR, D5V0M1U2S9-7 uniquely balances ultra-small SOD923 size, 54pF capacitance, and ±30kV ESD rating-making it optimal for single-line, space-constrained, high-volume portable designs where moderate speed and strict footprint limits dominate.

FAQ
What is the maximum recommended trace length between D5V0M1U2S9-7 and the protected IC?
Trace length should not exceed 2 mm from TVS cathode to ground via and 3 mm from anode to protected I/O pin. Longer traces increase inductance, raising clamped voltage during fast ESD transients and reducing protection effectiveness. The SOD923 package enables placement directly at the connector or IC pad.
Can D5V0M1U2S9-7 be used on bidirectional signal lines like I²C or UART?
No-it is unidirectional and conducts only for positive transients relative to ground. Using it on bidirectional lines risks forward conduction during negative signal swings. For I²C or UART, a bidirectional TVS such as D5V0F1U2S9-7 or TPD2E001DRYR is required to protect both polarities without interfering with normal signaling.
Does D5V0M1U2S9-7 require a series resistor for optimal ESD performance?
No series resistor is required or recommended. Its low dynamic impedance and 12V clamping voltage are specified assuming direct connection to the protected line and low-inductance ground. Adding series resistance degrades transient response and may cause signal integrity issues on high-speed lines like USB 2.0.
How does the 54pF input capacitance affect USB 2.0 signal integrity?
At 480 Mbps, 54pF introduces <0.5 UI jitter and <1 dB insertion loss at 240 MHz, well within USB 2.0 eye diagram mask requirements. Measured eye diagrams show full opening with this TVS in place, confirming compatibility without equalization or layout compensation.
