Product details
Overview
PESD5V0S1BB from Nexperia is a bidirectional ESD protection diode in SOD523 (SC-79) package, designed to protect one signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 5 V reverse standoff voltage, 14 V clamping voltage at 12 A surge, and 35–45 pF capacitance - deployed in high-speed USB, audio, and HDMI interfaces of portable electronics.
For engineers reviewing the PESD5V0S1BB datasheet, PESD5V0S1BB pinout, PESD5V0S1BB application, or PESD5V0S1BB equivalent, key selection criteria include low clamping voltage for sensitive IC protection, ultra-low leakage (<5 nA) for battery-powered systems, sub-1.3 mm² footprint for space-constrained layouts, and verified IEC 61000-4-5 surge immunity (12 A, 8/20 µs).
Technical Context
This dual-cathode, bidirectional TVS diode implements a symmetrical back-to-back PN junction configuration across pins 1 and 2, enabling clamping of both positive and negative transients without polarity dependence. Its 50 Ω differential resistance and 14 V clamping at 12 A ensure fast response and minimal voltage overshoot during ESD events.
The device operates within −55 °C to +150 °C ambient range, with junction temperature limited to 150 °C. Its 35–45 pF capacitance at 1 MHz and 0 V bias supports signal integrity on lines up to ~300 MHz, while 5 nA reverse leakage at 5 V ensures negligible standby current drain in always-on circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous DC voltage the diode blocks without conduction; defines safe operating margin below system rail. |
| Clamping Voltage | 14 V at 12 A - Peak voltage seen by protected IC during worst-case IEC 61000-4-5 surge; limits stress on downstream logic. |
| ESD Withstand | ±30 kV contact per IEC 61000-4-2 - Validated immunity to human-body model discharges without degradation. |
| Diode Capacitance | 35–45 pF at 1 MHz - Low enough to avoid signal distortion on USB 2.0 or audio differential pairs. |
| Peak Pulse Power | 130 W - Sustains transient energy from 8/20 µs surges without thermal failure. |
| Reverse Leakage | 5 nA at 5 V - Enables use in battery-backed or low-power wake-up circuits without measurable drain. |
| Package | SOD523 (SC-79), 1.2 × 0.8 × 0.6 mm - Ultra-compact footprint compatible with fine-pitch PCB assembly and 0201 land patterns. |
Pinout & Package
SOD523 (SC-79) plastic surface-mount package with 2 leads, 1.2 mm × 0.8 mm × 0.6 mm body size and cathode band marking (L7 code). Thermal pad not present; soldering per JEDEC J-STD-020 reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Forms one half of symmetrical clamp; connects to protected line when paired with Pin 2 as return path to ground. |
| 2 | Cathode (Diode 2) | Completes bidirectional structure; enables clamping of both polarities between Pins 1 and 2 without external grounding. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Back-to-back diode architecture protects AC-coupled or bipolar signal lines (e.g., USB D+/D−, audio L/R) without polarity constraints. |
| Low clamping voltage | 14 V at 12 A ensures protected ICs (e.g., USB transceivers rated to 5.5 V) remain within absolute maximum ratings during surge events. |
| Ultra-low capacitance | 35–45 pF minimizes insertion loss and phase shift on high-speed data lines, preserving eye diagram integrity up to 480 Mbps. |
| Sub-5 nA leakage | Enables direct integration into always-on sensor interface paths (e.g., headset detection, touch controller inputs) without compromising battery life. |
| IEC-compliant robustness | Validated to IEC 61000-4-2 level 4 (±30 kV contact) and IEC 61000-4-5 (12 A, 8/20 µs), meeting industrial and consumer EMI immunity requirements. |
Applications
| USB 2.0 Interface Protection | HDMI Hot-Plug Detection Line |
|---|---|
|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in smartphones and docking stations from ESD during cable insertion/removal. IC Role / Device Role: Bidirectional transient voltage suppressor placed directly at connector, shunting ESD current to ground before reaching PHY IC. Use Value: 35–45 pF capacitance avoids signal rise-time degradation; 14 V clamping prevents latch-up in 3.3 V USB transceivers. |
Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) line against ESD during display connection/disconnection in tablets and monitors. IC Role / Device Role: Signal-line protector between source (GPU) and sink (display) HPD pins, operating in open-drain configuration. Use Value: 5 nA leakage preserves pull-up voltage integrity; 5 V standoff matches standard 5 V HPD supply rail. |
| Smartphone Audio Jack | Wireless Headset Microphone Input |
|
Use Scenario: Shielding TRRS audio jack tip/ring contacts from user-hand ESD in handheld devices. IC Role / Device Role: Dual-line protector for left/right audio channels and microphone input, mounted adjacent to jack PCB footprint. Use Value: SOD523 size fits tight mechanical clearances; bidirectional operation handles both positive and negative transients on AC-coupled audio paths. |
Use Scenario: Protecting MEMS microphone bias and output lines in Bluetooth earbuds exposed to repeated handling ESD. IC Role / Device Role: Low-capacitance clamp on microphone VDD and OUT nodes, minimizing noise coupling into analog front-end. Use Value: 14 V clamping prevents overvoltage damage to 1.8 V mic ASICs; 50 Ω dynamic resistance ensures fast turn-on during nanosecond transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Unidirectional configuration; 5.5 V standoff; 15 V clamping at 12 A; 50 pF capacitance. | Requires separate ground reference; unsuitable for floating or AC-coupled lines without DC bias. | Select only if protecting unidirectional signals with defined ground reference and higher capacitance tolerance. |
| Vishay VEML6030X01 | Not applicable - optical ambient light sensor, not an ESD diode. | N/A - incorrect functional category. | Exclude; misidentified part with no ESD protection capability. |
Compared with PESD5V0S1BB, NUP4105MR6T1G offers similar surge rating but lacks true bidirectionality and adds 5 pF capacitance, reducing high-frequency performance; VEML6030X01 is unrelated and must be discarded from ESD protection consideration.

FAQ
What is the maximum operating temperature for PESD5V0S1BB?
The PESD5V0S1BB has a maximum junction temperature of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance (RθJA) is not specified in the datasheet, but the SOD523 package relies on PCB copper area for heat dissipation during transient events.
Can PESD5V0S1BB protect a 3.3 V I/O line without affecting signal integrity?
Yes - with 5 V reverse standoff and 14 V clamping, it remains non-conductive during normal 3.3 V operation while limiting transients to safe levels. Its 35–45 pF capacitance introduces negligible loading on typical 50 Ω impedance traces used in USB or audio interfaces.
How is the bidirectional behavior implemented in this two-pin device?
PESD5V0S1BB uses two anti-parallel diodes sharing a common node internally - Pin 1 and Pin 2 each serve as cathodes, forming a symmetrical structure that conducts equally for positive or negative voltage excursions beyond the breakdown threshold (~5.5 V).
Is PESD5V0S1BB automotive qualified?
No - the datasheet does not state AEC-Q200 qualification, and Nexperia's legal disclaimers explicitly classify it as non-automotive. It is intended for consumer and industrial portable electronics, not safety-critical vehicle systems.
