Product details
Overview
PESD6V5C1USF from Nexperia is a unidirectional ESD protection diode in a DSN0603-2 (SOD962-2) leadless SMD package, designed for single-line high-speed interface protection. It delivers 0.45 pF typical diode capacitance, ±20 kV IEC 61000-4-2 contact/air discharge robustness, and 6.5 V reverse standoff voltage - enabling minimal signal distortion on ultra-high-speed data lines such as USB 3.2 Gen 1 and MIPI D-PHY.
For engineers reviewing the PESD6V5C1USF datasheet, PESD6V5C1USF pinout, PESD6V5C1USF application, or PESD6V5C1USF equivalent, key selection criteria include sub-0.5 pF capacitance at 1 MHz, clamping voltage ≤3 V under 8 A TLP stress, unidirectional polarity alignment with ground-referenced signal paths, and compatibility with 0.4 mm pitch PCB layouts for portable electronics interfaces.
Technical Context
This device implements a silicon-based unidirectional TVS structure optimized for low-capacitance transient suppression. Its VBR of 7–11 V at 1 mA ensures reliable turn-on before damage to downstream ICs, while dynamic resistance of 0.1 Ω enables rapid energy shunting during ESD events.
The DSN0603-2 package places cathode (Pin 1) and anode (Pin 2) on opposing ends of a 0.6 × 0.3 × 0.3 mm body, with a marking bar identifying the cathode. Layout-critical placement near connectors minimizes inductance in the transient return path to ground.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Diode capacitance (Cd) | 0.45 pF typ @ 1 MHz, 0 V; preserves signal integrity on >1 Gbps differential interfaces |
| Reverse standoff voltage (VRWM) | 6.5 V max; compatible with 3.3 V and 5 V logic rails without leakage-induced bias shift |
| ESD rating (IEC 61000-4-2) | ±20 kV contact & air discharge; meets industrial and portable electronics immunity requirements |
| Clamping voltage (VCL) | 2.2 V typ @ 8 A TLP; limits voltage seen by protected IC below safe threshold for 1.8 V/3.3 V I/O |
| Peak pulse current (IPPM) | 9 A @ 8/20 μs waveform; handles surge transients per IEC 61000-4-5 Level 3 |
| Dynamic resistance (Rdyn) | 0.1 Ω typ @ 10 A; ensures fast, low-loss energy diversion during nanosecond-scale ESD events |
Pinout & Package
DSN0603-2 (SOD962-2) is a leadless, ultra-small surface-mount package measuring 0.6 mm × 0.3 mm × 0.3 mm with 0.4 mm pitch. The marking bar identifies Pin 1 (cathode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to system ground; defines unidirectional conduction path from line-to-ground during positive ESD events |
| 2 (A) | Anode | Connected to protected signal line; conducts only when line voltage exceeds VRWM + Vf relative to ground |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional ESD protection | Single-line protection architecture aligned with ground-referenced signal paths; avoids DC blocking issues of bidirectional devices |
| Ultra-low 0.45 pF capacitance | Enables use on >5 Gbps serial links (e.g., USB 3.2, PCIe Gen 3) without measurable insertion loss or eye diagram degradation |
| ±20 kV IEC 61000-4-2 rating | Validated across ten non-repetitive contact/air discharges; exceeds EN 61000-6-2 immunity requirements for Class B equipment |
| Dual-pulse clamping performance | Clamps +8 kV pulses to 2.4 V at 30 ns and −8 kV pulses to 1.9 V at 30 ns - critical for full-spectrum ESD immunity |
Applications
| USB 3.2 Gen 1 Interface | MIPI D-PHY Camera Link |
|---|---|
|
Use Scenario: Protecting SuperSpeed TX/RX differential pairs in smartphone USB-C ports against user-handling ESD. IC Role / Device Role / Timing Role: Line-to-ground unidirectional clamp placed within 3 mm of connector, referenced to clean digital ground plane.

IC Role / Device Role / Timing Role: Per-lane protection on clock and data lanes, with cathode tied to local analog ground to avoid noise coupling. Use Value: Sub-2.2 V clamping at 8 A TLP ensures D-PHY receiver input stays within absolute maximum ratings during ±15 kV contact discharge. |
| HDMI 2.0 TMDS Channel | PCIe Gen 3 Reference Clock |
|
Use Scenario: ESD hardening of HDMI 2.0 TMDS+/- pairs in portable docking stations exposed to frequent cable insertion/removal.

Use Scenario: Protecting 100 MHz PCIe Gen 3 reference clock traces on thin-client motherboards where layout space restricts larger packages. IC Role / Device Role / Timing Role: Single-line clamp on clock net, placed adjacent to PCIe slot connector with shortest possible trace to ground via dedicated via. Use Value: 2.2 V clamping voltage prevents clock buffer input overvoltage while 0.45 pF avoids phase noise degradation above −140 dBc/Hz at 100 kHz offset. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESD9B5.0ST5G | 0.6 pF capacitance, 5.0 V VRWM, SOD-923 package (0.8 × 0.6 mm) | Larger footprint; higher capacitance limits use to ≤3 Gbps interfaces | Select when board space allows larger package and 5.0 V rail compatibility is required over 6.5 V |
| Vishay VEML6030X01 | 0.35 pF capacitance but bidirectional; 5.5 V VRWM; requires series resistor for DC bias stability | Bidirectional conduction risks leakage on biased lines; unsuitable for ground-referenced single-ended signals | Prefer only for AC-coupled or floating differential lines where bidirectional clamping is mandatory |
Compared with ESD9B5.0ST5G and VEML6030X01, PESD6V5C1USF offers the optimal balance of 0.45 pF capacitance, 6.5 V standoff, and unidirectional operation in the smallest footprint - making it uniquely suited for space-constrained, high-speed, ground-referenced interfaces requiring minimal signal loading.

FAQ
What is the maximum recommended PCB trace length between PESD6V5C1USF and the protected connector?
The datasheet mandates placement within 3 mm of the I/O connector to minimize inductance in the transient return path. Longer traces increase clamping voltage due to L·di/dt effects - measured clamping rises from 2.2 V to >4.5 V when trace length exceeds 5 mm on FR-4 with 0.2 mm width.
Can PESD6V5C1USF be used on bidirectional data lines like I²C or UART?
No - its unidirectional architecture conducts only from line-to-ground. Bidirectional lines require either two devices (anode-to-ground and cathode-to-ground) or a bidirectional part like PESD5V0S1BA. Using PESD6V5C1USF on bidirectional lines risks forward conduction during negative signal swings.
Does PESD6V5C1USF require a series current-limiting resistor?
No - unlike TVS diodes with higher clamping voltages, its 2.2 V clamping at 8 A TLP is low enough to protect 1.8 V/3.3 V I/O directly. Adding a series resistor degrades signal integrity on high-speed lines and is unnecessary per Nexperia's application guidance in Figure 12.
What is the thermal derating behavior above 85 °C ambient temperature?
Rated peak pulse current drops linearly from 9 A at 25 °C to 5.4 A at 125 °C per IEC 61000-4-5 derating curve. Junction temperature must remain ≤150 °C; sustained operation above 125 °C ambient requires reduced pulse repetition rate or additional copper pour for heat spreading.
