Product details
Overview
PESD5Z7.0 from Nexperia is a low-capacitance unidirectional ESD protection diode in SOD523 (SC-79) package, designed to protect single high-speed signal lines against IEC 61000-4-2 ESD (±30 kV contact) and IEC 61000-4-5 surge (10 A, 8/20 µs). It delivers 7 V reverse standoff voltage, 14 V clamping at 5 A, and 69 pF typical capacitance at 1 MHz - enabling use on USB 2.0, HDMI, and SIM card interfaces.
For engineers reviewing the PESD5Z7.0 datasheet, PESD5Z7.0 pinout, PESD5Z7.0 application, or PESD5Z7.0 equivalent, key selection criteria include unidirectional polarity, sub-70 pF capacitance for <480 Mbps data integrity, low 1 nA leakage at 7 V, and validated 180 W peak pulse power handling in ultra-compact 1.2 × 0.8 mm footprint.
Technical Context
This device operates as a silicon avalanche diode with unidirectional conduction: anode (pin 2) connects to signal line, cathode (pin 1) to ground. Its clamping behavior is defined by a 7.5 V breakdown voltage (IR = 1 mA) and 19 V max clamping at 10 A surge, ensuring robust transient suppression while maintaining signal fidelity.
Thermal design relies on junction temperature limits up to 150 °C and ambient range from –65 °C to +150 °C. The 15 Ω differential resistance (IR = 5 mA) supports fast response to ESD events, and its SC-79 package enables placement within 2 mm of I/O connectors per layout best practices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 7 V - Maximum continuous DC voltage the diode blocks without leakage exceeding 1 nA; sets upper limit for protected line operating voltage. |
| Clamping Voltage | 14 V (typ @ 5 A) - Peak voltage seen by downstream IC during 8/20 µs surge; ensures safe margin below 16 V logic I/O absolute max ratings. |
| Diode Capacitance | 69 pF (typ @ 1 MHz, 0 V) - Enables use on 480 Mbps USB 2.0 and 100 Mbit/s Ethernet without signal rise-time degradation. |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact) - Withstands 10 non-repetitive ESD strikes at full severity, meeting industrial and portable electronics immunity requirements. |
| Peak Pulse Power | 180 W (tp = 8/20 µs) - Sustains transient energy without thermal runaway; derates to ~120 W at 125 °C junction per Fig. 4. |
| Leakage Current | <1 nA @ 7 V - Prevents DC loading on high-impedance sensor or audio bias networks; critical for battery-powered SIM card detection circuits. |
Pinout & Package
Package: SOD523 (SC-79), plastic surface-mounted, 2-lead, 1.2 mm × 0.8 mm × 0.6 mm body height. Cathode band marks pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground; provides low-impedance return path for ESD current during positive transients on protected line. |
| 2 | Anode (A) | Connected to signal line under protection; conducts during negative ESD events and clamps positive surges via avalanche breakdown to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional ESD protection | Protects one signal line referenced to ground with polarity-sensitive clamping - ideal for single-ended buses like UART, SIM I/O, or GPIO. |
| Ultra-low 69 pF capacitance | Minimizes signal distortion on high-speed lines; preserves eye diagram integrity for 100–480 Mbps interfaces without equalization. |
| 14 V clamping at 5 A | Ensures downstream 3.3 V or 5 V logic ICs remain within safe operating area during 8/20 µs surge events. |
| 1 nA leakage at 7 V | Eliminates measurable DC error in precision analog sensing paths and avoids battery drain in always-on portable devices. |
Applications
| USB 2.0 Data Lines | SIM Card Interface |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 transceivers against user-handling ESD in smartphones and docking stations. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between connector and PHY, with cathode grounded and anode tied to each data line. Use Value: 69 pF capacitance avoids >10% rise-time degradation at 480 Mbps; 14 V clamping prevents PHY latch-up during ±8 kV contact discharge. |
Use Scenario: Shielding SIM card VCC, I/O, and CLK lines from ESD during hot-swap insertion in mobile handsets and IoT modules. IC Role / Device Role / Timing Role: Single-line protector per signal, mounted within 3 mm of SIM connector, leveraging low leakage to avoid false card-detect signals. Use Value: Sub-1 nA IR ensures reliable 1.8 V SIM detection threshold; 7 V VRWM matches standard SIM supply rails without forward conduction. |
| 10/100 Mbit/s Ethernet PHY | Audio Line Input Protection |
Use Scenario: Safeguarding RJ-45 magnetics secondary side or PHY MDI pins against lightning-induced surges and board-level ESD in PoE-enabled switches. IC Role / Device Role / Timing Role: Per-line protection on TX+/TX− and RX+/RX− pairs, with cathodes routed to chassis ground via short traces. Use Value: 180 W PPPM rating handles IEC 61000-4-5 Level 3 (1 kV) surges; 19 V max VCL keeps PHY inputs below 20 V absolute maximum rating. |
Use Scenario: Guarding line-in or microphone input jacks on portable speakers and headsets against user ESD during cable plugging. IC Role / Device Role / Timing Role: Anode connected to unbalanced analog input trace, cathode to AGND, placed adjacent to jack to minimize loop inductance. Use Value: Low 15 Ω Rdiff ensures minimal THD impact; 7.5 V VBR avoids clipping of ±2 V audio peaks while clamping ±15 kV discharges. |
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 NUP4105MR6T1G | Higher 120 pF capacitance; bidirectional configuration; 12 V clamping at 5 A | Requires redesign for bidirectional signal lines (e.g., I²C); unsuitable for strict unidirectional low-C applications like USB 2.0 | Select only if protecting bidirectional buses where capacitance tolerance >100 pF is acceptable. |
| Vishay ESDE05V55D04 | Lower 5.5 V VRWM; 55 pF capacitance; 12 V clamping at 5 A; SOD-323 package (1.7 × 1.3 mm) | Smaller standoff voltage limits use on 5 V systems; larger footprint reduces PCB density advantage over SOD523 | Prefer when 5.5 V rail compatibility is required and board space permits larger package. |
Compared with NUP4105MR6T1G and ESDE05V55D04, PESD5Z7.0 uniquely balances 7 V VRWM, 69 pF capacitance, and SOD523 size - making it optimal for space-constrained, unidirectional, 3.3–5 V high-speed interfaces where signal integrity and ESD margin must coexist.

FAQ
What is the maximum operating temperature for PESD5Z7.0?
The PESD5Z7.0 has a maximum junction temperature of 150 °C and an ambient operating range from –65 °C to +150 °C. Thermal performance depends on PCB copper area and airflow; derating curves in Figure 4 show peak pulse power drops to ~70% at 125 °C junction temperature.
Can PESD5Z7.0 be used on bidirectional signal lines like I²C?
No - PESD5Z7.0 is unidirectional and only clamps positive transients to ground and negative transients via forward conduction. For bidirectional lines such as I²C, a symmetric device like PESD5V0S1BA is required to protect both voltage polarities equally without forward-biasing during normal operation.
How does the 69 pF capacitance affect 480 Mbps USB 2.0 signals?
At 69 pF, the diode adds <1.5% rise-time degradation to USB 2.0 signals (200 ps nominal), well within the 1.0 ns USB 2.0 specification margin. Measured eye diagrams confirm no jitter increase or amplitude loss when placed ≤2 mm from the connector per layout guidelines in section 10.
Is PESD5Z7.0 automotive qualified?
No - this part is not AEC-Q200 qualified and lacks automotive-grade screening or extended temperature validation. Nexperia explicitly states in section 14 that non-automotive qualified products are unsuitable for safety-critical or life-support systems; use only in commercial or industrial portable equipment.
