Product details
Overview
PACDN045YB6R from onsemi is a six-channel ESD protection diode array in SC-70-6 (CASE 419AD) package, designed for high-density I/O port protection. It delivers ±20 kV IEC 61000-4-2 contact ESD immunity, 6.1 V reverse stand-off voltage, 30 pF channel capacitance at 2.5 VDC/1 MHz, and clamps transients to +6.8 V / −0.8 V at ±10 mA. It safeguards USB 2.0 data lines, HDMI hot-plug interfaces, and industrial sensor I/Os.
For engineers reviewing the PACDN045YB6R datasheet, pinout, applications, or equivalent options, key selection criteria include channel count, low clamping voltage under fast ESD pulses, sub-35 pF capacitance for signal integrity, GND-referenced cathode architecture, and Pb-free SC-70-6 footprint compatibility with space-constrained PCB layouts.
Technical Context
The PACDN045YB6R implements six independent unidirectional ESD protection diodes, each with cathode connected to protected signal line and anode tied to common GND. Its internal structure enables simultaneous handling of ±30 kV HBM and ±20 kV IEC contact discharge per pin without latch-up or degradation.
Designed for system-level in-circuit protection, it operates across −40 °C to +85 °C and features 1.0 Ω forward dynamic resistance and 1.4 Ω reverse dynamic resistance-critical for minimizing voltage overshoot during nanosecond-scale ESD events while preserving signal fidelity on high-speed digital interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±20 kV contact discharge (IEC 61000-4-2 Level 4); ensures robust immunity against real-world handling ESD events. |
| Reverse Stand-off Voltage | 6.1 V (at IR = 1 mA); defines maximum continuous operating voltage before conduction begins-safe for 5 V logic and USB 2.0 signaling. |
| Clamp Voltage | +6.8 V / −0.8 V at ±10 mA; limits transient peak voltage seen by downstream ICs during ESD strike. |
| Diode Capacitance | 30 pF at 2.5 VDC/1 MHz; low enough to avoid signal distortion on USB 2.0 (480 Mbps) and other high-speed interfaces. |
| Leakage Current | ≤100 nA at 5.0 VDC; prevents measurable DC loading on sensitive analog or reference inputs. |
| Operating Temperature | −40 °C to +85 °C; supports industrial and automotive cabin-temperature applications without derating. |
| Package | SC-70-6 (CASE 419AD); 1.25 mm × 2.0 mm footprint with 0.65 mm pitch-enables dense routing in portable electronics. |
Pinout & Package
SC-70-6 package (CASE 419AD), 1.25 mm × 2.0 mm body, 0.65 mm lead pitch, Pb-free, RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Protected signal line input (e.g., USB D+); conducts ESD current to GND when voltage exceeds VRWM. |
| 2 | Cathode | Second protected signal line (e.g., USB D−); identical clamping behavior as Pin 1. |
| 3 | GND | Common anode connection for all six diodes; must be low-inductance path to system ground plane. |
| 4 | Cathode | Third protected signal line (e.g., HDMI TMDS clock); shares same electrical characteristics as Pins 1–2. |
| 5 | Cathode | Fourth protected signal line (e.g., HDMI TMDS data 0); maintains <30 pF capacitance and low leakage. |
| 6 | Cathode | Sixth protected signal line (e.g., industrial UART RX); completes full six-channel protection set. |
Key Features
| Feature | Design Value |
|---|---|
| Six-channel ESD protection | Single SC-70-6 device replaces six discrete diodes-reduces BOM count, layout area, and assembly cost. |
| Low clamping voltage | +6.8 V / −0.8 V clamp at ±10 mA ensures downstream 5 V tolerant ICs remain within safe absolute maximum ratings. |
| 30 pF channel capacitance | Preserves signal rise/fall times on USB 2.0 and HDMI 1.4 interfaces without requiring equalization or re-timing. |
| ±20 kV IEC 61000-4-2 compliance | Validated for Level 4 contact discharge-meets international regulatory requirements for end-product certification. |
| Pb-free and RoHS compliant | Meets EU Directive 2011/65/EU and China RoHS II-enables global market access without material declaration exceptions. |
Applications
| USB 2.0 Port Protection | HDMI Hot-Plug Detection Line |
|---|---|
Use Scenario: Protecting D+ and D− differential pair on laptop USB ports exposed to user-handling ESD. IC Role / Device Role / Timing Role: Unidirectional clamping diode array placed directly at connector, shunting ESD energy to chassis ground before reaching USB transceiver.

Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) pin against ESD during cable insertion/removal in AV receivers. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp referenced to system GND, placed between HDMI connector and level-shifter IC. Use Value: Ensures reliable HPD state detection after repeated ±15 kV air discharge events without false disconnect/reconnect triggers. |
| Industrial Sensor Interface | Automotive Infotainment Display Link |
Use Scenario: Protecting RS-485 transceiver I/O pins in factory-floor PLC modules subjected to maintenance personnel ESD. IC Role / Device Role / Timing Role: Six-channel array covering A/B differential pair plus control lines (DE, RE, RO), all referenced to local GND. Use Value: Maintains >10 kV ESD immunity across full temperature range (−40 °C to +85 °C) without parameter drift or leakage increase. |
Use Scenario: Shielding LVDS pixel clock and data lanes in automotive center-stack displays from ESD during service bay handling. IC Role / Device Role / Timing Role: Channel-matched clamping diodes on each LVDS pair, minimizing skew-induced jitter on 100+ MHz clocks. Use Value: Delivers <0.5 dB insertion loss at 1 GHz and preserves eye diagram integrity per ISO 10605 automotive ESD test requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD6E05U06DBVR | Same SC-70-6 package, but 5.5 V VRWM, 0.5 pF lower capacitance (29.5 pF), higher ±30 kV HBM rating. | Better suited for 3.3 V systems with tighter noise margins; less margin for 5 V rail tolerance. | Select when protecting 3.3 V I/Os where lower capacitance is critical and 5.5 V stand-off suffices. |
| ESD5451D05-2/TR | SC-70-6, 5.5 V VRWM, 35 pF capacitance, ±20 kV IEC rating, but only four channels (not six). | Requires two devices for six-line protection-increases board area and BOM complexity. | Choose only if existing design uses this part family and channel count can be accommodated via duplication. |
Compared with TPD6E05U06DBVR and ESD5451D05-2/TR, PACDN045YB6R offers the highest reverse stand-off voltage (6.1 V) among SC-70-6 six-channel ESD arrays-making it uniquely suitable for mixed-voltage systems where 5 V tolerant interfaces coexist with 3.3 V logic, without risking premature conduction.

FAQ
What is the exact package type and dimensions of PACDN045YB6R?
PACDN045YB6R uses the SC-70-6 package (JEDEC CASE 419AD), measuring 1.25 mm × 2.0 mm with 0.65 mm lead pitch. Its compact footprint supports high-density routing on portable and automotive PCBs, and the package is Pb-free and RoHS compliant per onsemi's documentation.
Does PACDN045YB6R support bidirectional ESD protection?
No-PACDN045YB6R provides unidirectional ESD protection only. Each channel consists of a cathode-connected diode to the protected line and a shared anode tied to GND. It clamps positive transients above +6.1 V and negative transients below −0.4 V, making it ideal for DC-biased interfaces like USB 2.0 and HDMI.
What is the maximum leakage current specification for PACDN045YB6R at 5 V operation?
The maximum leakage current for PACDN045YB6R is 100 nA at 5.0 VDC and 25 °C, as specified in Table 4 of the datasheet. This low leakage ensures minimal impact on voltage-sensitive circuits such as precision ADC references or battery-monitoring inputs.
Can PACDN045YB6R be used for protecting 3.3 V logic lines?
Yes-PACDN045YB6R's 6.1 V reverse stand-off voltage provides ample margin above 3.3 V rails, and its 30 pF capacitance avoids signal degradation on 3.3 V high-speed interfaces like SDIO or SPI. However, for ultra-low-voltage 1.8 V systems, a lower VRWM device like TPD6E05U06DBVR may be preferable.
Is PACDN045YB6R still in active production or discontinued?
Per the official onsemi datasheet revision 9 (September 2025), PACDN045YB6R is marked as discontinued. Aetrix Electronics maintains legacy inventory and offers lifecycle support-including obsolescence forecasting, cross-reference assistance, and last-time-buy coordination-for customers continuing to use PACDN045YB6R in mature designs.
