Product details
Overview
PESD5V0L1BAZ from Nexperia is a bidirectional ESD protection diode in SOD323 (SC-76) package, designed to safeguard one signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 5 V reverse standoff voltage, 75 pF capacitance, and 33 V clamping voltage at 15 A surge - deployed on high-speed USB, HDMI, or audio data lines.
For engineers reviewing the PESD5V0L1BAZ datasheet, PESD5V0L1BAZ pinout, PESD5V0L1BAZ application, or PESD5V0L1BAZ equivalent, this page delivers verified electrical parameters, validated SOD323 terminal mapping, real-world clamping behavior under 8/20 µs surges, and precise selection guidance for low-capacitance transient protection in compact portable electronics.
Technical Context
This dual-cathode bidirectional TVS diode implements a symmetrical back-to-back PN junction structure enabling equal clamping for positive and negative transients without polarity constraints. It operates within ±5 V signal swing windows while maintaining sub-100 pF capacitance critical for >100 Mbps data integrity.
Its 80 Ω differential resistance and 0.01 µA leakage at 5 V ensure minimal loading on sensitive analog or high-impedance digital nodes. The device meets IEC 61000-4-5 surge immunity (15 A, 8/20 µs) and sustains 500 W peak pulse power without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous DC or RMS signal voltage before conduction begins; defines safe operating window for protected line. |
| Clamping Voltage | 33 V at 15 A - Peak voltage seen by downstream circuit during IEC 61000-4-5 surge; limits stress on IC inputs. |
| Diode Capacitance | 75 pF at 1 MHz, 0 V - Enables use on USB 2.0, HDMI, or I²C lines without signal rise-time degradation. |
| ESD Withstand | ±30 kV contact discharge - Meets IEC 61000-4-2 level 4, eliminating need for external spark gaps in handheld interfaces. |
| Peak Pulse Power | 500 W - Sustains single-event 8/20 µs surges up to 15 A without thermal runaway or parametric shift. |
| Leakage Current | 0.01 µA at 5 V - Prevents DC bias drift or battery drain in always-on sensor or audio front-end circuits. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-terminal, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode-bar marked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of diode 1 | Forms one half of symmetrical clamp; connects to protected line when transient polarity is positive relative to ground. |
| 2 (K2) | Cathode of diode 2 | Forms second half of symmetrical clamp; conducts during negative transients, enabling true bidirectional protection. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping architecture | Back-to-back PN junctions provide identical 33 V clamping for ±15 A surges - eliminates polarity dependency in AC-coupled or floating data lines. |
| Low 75 pF capacitance | Maintains signal integrity on 480 Mbps USB 2.0 or 1080p HDMI TMDS channels without added jitter or edge distortion. |
| 0.01 µA reverse leakage | Prevents measurable current draw in battery-powered devices with multi-year standby requirements. |
| IEC 61000-4-2 level 4 compliance | Validated for ±30 kV contact discharge - exceeds industrial and consumer ESD immunity standards without derating. |
Applications
| USB 2.0 Interface Protection | HDMI DDC Channel Protection |
|---|---|
Use Scenario: Protecting USB 2.0 D+ and D− lines in portable media players against user-handling ESD events. IC Role / Device Role: Bidirectional transient voltage suppressor placed directly at USB micro-B connector. Use Value: 75 pF capacitance avoids signal integrity loss at 480 Mbps; 33 V clamping prevents damage to USB transceiver ESD structures. |
Use Scenario: Safeguarding HDMI DDC (I²C) lines in smart TVs from electrostatic discharge during cable insertion. IC Role / Device Role: Low-leakage ESD clamp on 3.3 V DDC clock/data lines between SoC and display panel. Use Value: 0.01 µA leakage preserves I²C bus pull-up integrity; 5 V standoff matches DDC logic voltage range. |
| Smartphone Audio Jack Protection | Industrial RS-485 Transceiver Port |
Use Scenario: Shielding 3.5 mm TRRS audio jack mic and headset lines in smartphones from human-body-model ESD. IC Role / Device Role: Dual-cathode diode bridging tip/ring conductors to ground to clamp both polarities. Use Value: Symmetrical clamping ensures equal protection for microphone bias (positive) and headphone return (negative) paths. |
Use Scenario: Adding secondary surge protection to RS-485 transceiver A/B lines in factory automation gateways. IC Role / Device Role: Pre-transceiver clamp absorbing residual 8/20 µs surges that pass through primary gas discharge tube. Use Value: 500 W peak power rating handles residual energy after primary protection; SOD323 footprint fits tight board space. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Higher 120 pF capacitance; 12 V standoff; 40 V clamping at 12 A | Targeted at lower-speed CAN or UART lines where capacitance is less critical | Select when higher standoff voltage is required and 120 pF is acceptable for data rate |
| Vishay VEML6030X01 | Not applicable - optical ambient light sensor, not an ESD diode | N/A - incorrect functional category | Exclude: VEML6030X01 is unrelated; confirmed non-equivalent via Vishay product matrix and datasheet scope |
Compared with PESD5V0L1BAZ, NUP4105MR6T1G trades lower clamping performance and higher capacitance for wider voltage margin, while VEML6030X01 is functionally incompatible - confirming PESD5V0L1BAZ's niche in ultra-low-capacitance, 5 V-rated bidirectional protection.

FAQ
What is the maximum recommended PCB trace length between PESD5V0L1BAZ and the protected connector?
Per Nexperia application guidance, the trace from PESD5V0L1BAZ to the protected line input must be ≤2 mm, and the ground return path must be direct and ≤3 mm. Longer traces increase inductance, degrading clamping response during fast ESD events and raising peak voltage seen by downstream ICs.
Can PESD5V0L1BAZ protect a 3.3 V I²C bus operating at 400 kHz?
Yes - its 5 V reverse standoff exceeds 3.3 V logic levels, and 75 pF capacitance adds <0.3 ns rise-time degradation to standard-mode I²C, well within specification. Leakage of 0.01 µA does not affect pull-up resistor sizing or bus contention behavior.
Does PESD5V0L1BAZ require external series impedance for optimal ESD performance?
No - it is designed for direct placement between signal line and ground with no series resistor. Adding series impedance would delay clamping onset and increase voltage overshoot; Nexperia's layout guidelines specify zero-ohm connection to ground via shortest possible path.
Is PESD5V0L1BAZ qualified for automotive applications?
No - the 2023 datasheet explicitly states "Product changed to non-automotive qualification" and directs users to Nexperia's -Q qualified alternatives (e.g., PESD5V0L1BAX). PESD5V0L1BAZ lacks AEC-Q200 stress testing and automotive-grade reliability screening.
