Product details
Overview
PESD5V0L1UB from Nexperia is a low-capacitance unidirectional ESD protection diode in SC-79 (SOD523) package, designed to protect a single signal line against IEC 61000-4-2 level 4 ESD events up to ±26 kV contact discharge. It features 25 pF typical capacitance, 12 V clamping voltage at 3.5 A, 5 V reverse standoff voltage, and 10 nA leakage at 5 V - enabling high-speed data line protection in portable electronics and SIM card interfaces.
For engineers reviewing the PESD5V0L1UB datasheet, PESD5V0L1UB pinout, PESD5V0L1UB application, or PESD5V0L1UB equivalent, this device is selected for ultra-low capacitance signal integrity preservation, precise 5 V rail alignment, and robust transient suppression on unidirectional lines such as USB D+, HDMI TMDS, or SIM I/O where minimal loading and fast response are critical.
Technical Context
This unidirectional TVS diode operates as a clamping device triggered by reverse-biased avalanche breakdown above 6.4 V, with a differential resistance of 30 Ω ensuring rapid voltage limiting during ESD transients. Its 8/20 µs surge rating supports 42 W peak pulse power per line, validated under IEC 61000-4-5 conditions.
The SC-79 package enables PCB-level integration near connectors, with cathode identification via marking bar and anode-cathode polarity optimized for ground-referenced positive-signal protection. Layout guidelines mandate minimal trace length between protected line and device to preserve clamping efficacy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - defines maximum continuous operating voltage before conduction begins; matches standard 5 V logic and interface rails. |
| Clamping Voltage | 12 V at 3.5 A - limits transient voltage seen by downstream ICs during 8/20 µs surges, protecting 3.3 V/5 V I/O structures. |
| Diode Capacitance | 25 pF at 1 MHz, 0 V - ensures minimal signal distortion on high-speed lines like FireWire or audio differential pairs. |
| ESD Rating | ±26 kV IEC 61000-4-2 contact discharge - exceeds industrial immunity requirements for handheld and peripheral ports. |
| Leakage Current | 10 nA at 5 V - prevents DC loading on sensitive analog or battery-backed signal paths such as SIM clock/data. |
| Breakdown Voltage | 6.8 V typical at 5 mA - provides defined turn-on margin above 5 V VRWM while avoiding false triggering. |
| Peak Pulse Power | 42 W - sustains energy dissipation for transient events without thermal runaway in compact SOD523 footprint. |
Pinout & Package
Package: SC-79 (SOD523), plastic surface-mounted, 2-lead, 1.2 mm × 0.8 mm × 0.6 mm body. Cathode identified by marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode | Connected to protected signal line; conducts during positive ESD transients when line voltage exceeds VRWM + VBR. |
| 2 (A) | Anode | Connected to system ground; completes current path during ESD clamping, requiring low-inductance ground routing. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional ESD Protection | Optimized for ground-referenced positive-signal lines (e.g., USB D+, SIM CLK), eliminating bidirectional leakage trade-offs. |
| 25 pF Typical Capacitance | Preserves signal rise/fall times on >100 Mbps data lines without RC filtering or jitter degradation. |
| 12 V Clamping at 3.5 A | Ensures downstream 3.3 V I/O cells remain within absolute maximum ratings during worst-case IEC 61000-4-2 pulses. |
| 10 nA Reverse Leakage | Prevents measurable current draw on battery-powered SIM card interfaces or always-on sensor lines. |
| SC-79 (SOD523) Footprint | Enables placement within 2 mm of USB micro-B or nano-SIM connectors, minimizing transient loop inductance. |
Applications
| USB 2.0 Data Lines | SIM Card Interface |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 ports against user-handling ESD in smartphones and docking stations. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between connector and USB transceiver, referenced to chassis ground. Use Value: 25 pF capacitance avoids signal integrity loss at 480 Mbps; 12 V clamping prevents PHY latch-up during ±15 kV contact discharge. |
Use Scenario: Shielding SIM VCC, I/O, CLK, and RST pins from ESD during hot-swap insertion in mobile handsets and IoT modules. IC Role / Device Role / Timing Role: Discrete ESD suppressor per signal line, with cathode tied to each SIM pin and anode to clean ground plane. Use Value: 10 nA leakage avoids battery drain on standby SIM circuits; 5 V VRWM aligns precisely with SIM 3 V/5 V dual-voltage operation. |
| FireWire (IEEE 1394) Ports | High-Speed Audio Interfaces |
Use Scenario: Safeguarding FireWire TPB and TPA differential pairs in digital camcorders and audio interfaces exposed to frequent cable connect/disconnect events. IC Role / Device Role / Timing Role: Per-line unidirectional protection on each conductor, leveraging low capacitance to maintain 400 Mbps signaling integrity. Use Value: 25 pF capacitance minimizes skew between differential signals; 42 W surge rating handles repeated hot-plug transients. |
Use Scenario: Protecting I²S, SPDIF, or AES3 digital audio outputs in professional mixers and DACs where ESD-induced clicks must be eliminated. IC Role / Device Role / Timing Role: Point-of-entry clamp on transmitter output pins, grounded to audio ground plane to avoid ground bounce coupling. Use Value: 12 V clamping prevents latch-up in CMOS output drivers; low leakage avoids DC offset in AC-coupled audio paths. |
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 capacitance (35 pF typ), lower clamping (9.5 V at 1 A), dual-channel configuration | Requires layout adaptation for single-line use; better suited for space-constrained multi-line protection | Select when multi-line integration outweighs capacitance penalty on individual high-speed lines |
| Vishay ESDE05C1-2 | Lower VRWM (3.3 V), higher ESD rating (±30 kV), same SOD523 package | Designed for 3.3 V systems only; incompatible with 5 V signal rails without level-shifting | Choose only for 3.3 V-only designs requiring extended ESD margin beyond IEC level 4 |
Compared with NUP4105MR6T1G and ESDE05C1-2, PESD5V0L1UB uniquely balances 5 V rail compatibility, 25 pF signal transparency, and ±26 kV protection in a proven single-line SOD523 solution - making it optimal for USB, SIM, and FireWire where voltage alignment and bandwidth preservation are non-negotiable.

FAQ
Is PESD5V0L1UB suitable for bidirectional signal lines like USB D+/D− differential pairs?
No - PESD5V0L1UB is unidirectional and protects only positive-going transients relative to ground. For true bidirectional lines such as USB differential pairs, two devices per line (anode-to-ground and cathode-to-ground configurations) or a dedicated bidirectional part like PESD5V0S1BA is required to handle both polarities.
What is the maximum recommended PCB trace length between PESD5V0L1UB and the protected connector?
Nexperia recommends keeping the trace from the protected line to the cathode (Pin 1) under 2 mm, and the anode (Pin 2) to a low-inductance ground plane via ≤1 mm. Longer traces increase inductance, degrading clamping response and allowing voltage overshoot beyond the specified 12 V.
Does PESD5V0L1UB meet automotive AEC-Q200 requirements?
No - PESD5V0L1UB is not AEC-Q200 qualified. It is rated for industrial temperature range (−55 °C to +150 °C) but lacks automotive-specific stress testing, qualification reports, or PPAP documentation. Automotive applications require parts explicitly marked as AEC-Q200 compliant.
Can PESD5V0L1UB replace PESD5V0L1BA in existing designs?
Yes - PESD5V0L1UB and PESD5V0L1BA share identical electrical specs, SC-79 package, and pinout. The 'UB' suffix denotes tape-and-reel packaging per JEDEC J-STD-020 moisture sensitivity level 1, while 'BA' indicates bulk packaging; no functional or performance difference exists between them.
