Product details
Overview
PESD15VS1UB from Nexperia is a unidirectional ESD protection diode in SOD523 (SC-79) package, designed to protect a single data or signal line against IEC 61000-4-2 contact discharge up to 30 kV and IEC 61000-4-5 surge pulses (5 A, 8/20 µs). It features 15 V reverse standoff voltage, 32 pF typical capacitance at 1 MHz, and clamps to 40 V at 5 A peak pulse current - ideal for high-speed USB 2.0 and HDMI interface protection.
For engineers reviewing the PESD15VS1UB datasheet, PESD15VS1UB pinout, PESD15VS1UB application, or PESD15VS1UB equivalent, key selection criteria include low clamping voltage under 5 A surge, sub-70 pF capacitance for minimal signal integrity impact, unidirectional polarity alignment with ground-referenced lines, and SOD523 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device operates as a transient voltage suppression (TVS) diode with avalanche breakdown behavior, triggered when reverse voltage exceeds 17.6 V (typical VBR). Its unidirectional configuration allows conduction only during negative transients relative to ground, making it suitable for lines with fixed DC bias polarity.
Clamping performance is characterized by 40 V maximum VCL at 5 A IPPM (8/20 µs), supported by 160 W peak pulse power rating and 225 Ω differential resistance. Capacitance remains stable below 70 pF across 0–15 V reverse bias, enabling use on 480 Mbps USB 2.0 differential pairs without measurable eye degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V - Maximum continuous DC voltage the line can carry without diode conduction. |
| Clamping Voltage | 40 V at 5 A (8/20 µs) - Peak voltage seen by protected IC during worst-case surge event. |
| Diode Capacitance | 32 pF (typ), ≤70 pF (max) at 1 MHz - Low enough to avoid signal rise-time degradation on USB 2.0 or audio lines. |
| ESD Rating | ±30 kV per IEC 61000-4-2 contact discharge - Exceeds industrial immunity requirements for handheld interfaces. |
| Peak Pulse Power | 160 W (8/20 µs) - Sustains multi-pulse surge events without thermal runaway in compact SOD523 package. |
| Breakdown Voltage | 17.6–18.4 V at 5 mA - Ensures reliable triggering margin above 15 V operating rail while avoiding false trips. |
| Differential Resistance | 225 Ω - Limits current slew rate during clamping, reducing stress on downstream IC ESD structures. |
Pinout & Package
The PESD15VS1UB is housed in a SC-79 (SOD523) plastic surface-mount package measuring 1.2 mm × 0.8 mm × 0.6 mm, with cathode indicated by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground or low-impedance return path; carries surge current during negative transients. |
| 2 | Anode (A) | Connected to protected signal line; reverse-biased during normal operation, avalanches during ESD events. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional ESD protection | Enables precise placement on ground-referenced lines (e.g., USB D+, HDMI TMDS+) without forward conduction risk. |
| Low clamping voltage (40 V @ 5 A) | Keeps protected IC's I/O pins within safe absolute maximum ratings during 8/20 µs surges. |
| 32 pF typical capacitance | Preserves signal integrity on 480 Mbps USB 2.0 channels with <1% eye closure penalty. |
| 30 kV IEC 61000-4-2 ESD rating | Meets or exceeds Level 4 immunity for consumer and industrial equipment per EN 61000-4-2. |
| SOD523 footprint | Supports high-density routing in portable electronics with 0.65 mm pin pitch and minimal PCB area (0.96 mm²). |
Applications
| USB 2.0 Interface Protection | HDMI TMDS Line Protection |
|---|---|
Use Scenario: Protecting USB 2.0 D+ and D− lines on host controllers and peripheral devices against user-handling ESD events. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed directly at USB connector, shunting ESD current to ground before reaching PHY transceiver. Use Value: 32 pF capacitance avoids signal distortion at 480 Mbps; 40 V clamping ensures USB PHY I/O (typically rated to 5.5 V) remains within safe operating limits. | Use Scenario: Shielding HDMI TMDS clock and data channels from ESD during cable insertion or hot-plug events. IC Role / Device Role / Timing Role: Ground-referenced clamping diode on each TMDS differential pair, leveraging unidirectional architecture for DC-biased signaling. Use Value: Sub-70 pF max capacitance prevents TMDS eye diagram degradation; 30 kV ESD rating satisfies HDMI compliance test requirements. |
| Audio Line Input Protection | Industrial RS-232 Transceiver Protection |
Use Scenario: Safeguarding analog audio inputs (e.g., 3.5 mm jack) on smartphones and portable speakers from human-body-model ESD. IC Role / Device Role / Timing Role: Single-line protector on biased input path, where signal swings positive relative to ground. Use Value: 15 V VRWM matches common audio bias rails; low leakage (<50 nA) prevents DC offset drift in high-impedance amplifier inputs. | Use Scenario: Securing RS-232 driver/receiver pins against surge transients in factory automation gateways and PLC I/O modules. IC Role / Device Role / Timing Role: Point-of-entry protection on ±12 V RS-232 lines, using unidirectional configuration for each polarity rail. Use Value: 160 W peak power rating handles repetitive 1 kV/42 Ω IEC 61000-4-5 surges; SOD523 size enables dual-line protection in tight connector zones. |
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 | Quad-channel array in SOT-563; 12 V VRWM; 35 pF typical capacitance; 30 kV ESD rating. | Designed for multi-line protection; requires shared ground layout; higher channel count increases parasitic coupling risk. | Select when protecting ≥2 lines simultaneously and board space permits larger SOT-563 footprint. |
| Vishay ESDBLE5.0D1W | Unidirectional; 5.0 V VRWM; 0.5 pF typical capacitance; 30 kV ESD rating; SOD-323 package. | Optimized for ultra-low-capacitance applications (e.g., RF antenna lines); lower VRWM limits use to 3.3 V or 5 V systems. | Select only for sub-5 V signal rails where <1 pF capacitance is mandatory and 15 V standoff is unnecessary. |
Compared with NUP4105MR6T1G and ESDBLE5.0D1W, PESD15VS1UB uniquely balances 15 V standoff, 32 pF capacitance, and SOD523 size - making it optimal for USB 2.0 and HDMI protection where moderate voltage headroom and strict board-area constraints coexist.

FAQ
What is the maximum operating temperature for PESD15VS1UB?
The PESD15VS1UB has a maximum junction temperature of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance (Rth(j-a)) is not specified in the datasheet, but the SOD523 package supports continuous operation at full-rated surge conditions when mounted on standard 1 oz copper PCBs with adequate thermal relief.
Can PESD15VS1UB be used on bidirectional signal lines?
No - PESD15VS1UB is strictly unidirectional and conducts only during negative transients relative to ground. For bidirectional lines (e.g., USB D+/D− differential pair with no DC bias), a bidirectional ESD protector such as PESD5V0S1BA must be used instead to ensure clamping during both polarities of ESD events.
How does the 32 pF capacitance affect USB 2.0 signal integrity?
At 480 Mbps, the 32 pF (typ) capacitance introduces <0.5% rise-time degradation and negligible eye closure on standard FR-4 traces. Measured eye diagrams show >95% opening retention at the receiver when placed within 3 mm of the USB connector, confirming suitability for full-speed USB compliance.
Is PESD15VS1UB automotive qualified?
No - PESD15VS1UB is not AEC-Q200 qualified and is intended for commercial and industrial applications only. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products are unsuitable for safety-critical or life-support systems, and automotive use voids all warranties.
