Product details
Overview
PACDN045YB6-LF from onsemi is a 6-channel ESD protection diode array in SC-70-6 (CASE 419AD) package, designed for high-speed data lines requiring low capacitance (30 pF), low clamping voltage (6.2–6.8 V positive / −0.4 to −1.2 V negative), and robust IEC 61000-4-2 Level 4 compliance (±20 kV contact discharge). It protects USB 2.0, HDMI, and serial interface pins against electrostatic discharge in portable electronics.
For engineers reviewing the PACDN045YB6-LF datasheet, pinout, applications, or equivalent options, key selection criteria include channel count (6), reverse stand-off voltage (6.1 V), leakage current (<100 nA at 5 V), dynamic resistance (1.0–1.4 Ω), and SC-70-6 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements six independent bidirectional TVS diodes with common GND anode configuration, enabling simultaneous protection of six signal lines. Each channel features matched clamping characteristics and low parasitic capacitance optimized for <480 Mbps USB 2.0 signaling integrity.
The internal structure uses silicon avalanche diodes with controlled breakdown and fast response time (<1 ns), meeting MIL-STD-883H HBM ESD rating >±30 kV and IEC 61000-4-2 contact discharge up to ±20 kV. All channels share a single GND terminal, simplifying layout and reducing ground loop risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | 6 independent ESD protection paths - supports full protection of dual USB 2.0 differential pairs plus two control lines. |
| Reverse Stand-off Voltage | 6.1 V at 1 mA - ensures no conduction during normal 5 V operation while providing margin before clamping onset. |
| Capacitance | 30 pF at 2.5 VDC, 1 MHz - preserves signal integrity for USB 2.0 (480 Mbps) and other high-speed interfaces. |
| Clamp Voltage | +6.2 V / −0.4 V at ±10 mA - limits transient overvoltage to safe levels for downstream 5 V-tolerant ICs. |
| ESD Rating | ±20 kV IEC 61000-4-2 contact discharge - exceeds Level 4 immunity requirement for consumer and industrial ports. |
| Leakage Current | ≤100 nA at 5 V - avoids loading of high-impedance signal lines or battery-powered sensor inputs. |
| Dynamic Resistance | 1.0 Ω (forward), 1.4 Ω (reverse) - minimizes voltage overshoot during fast ESD transients. |

Use Scenario: Shielding analog front-end inputs (e.g., ECG electrode leads, temperature sensor lines) in portable diagnostic devices from clinical handling ESD. IC Role / Device Role: High-impedance signal line protector with sub-100 nA leakage, placed between connector and instrumentation amplifier input. Use Value: Preserves DC accuracy and noise floor while suppressing ±20 kV transients that could otherwise saturate sensitive amplifiers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD6E05U06RTER (Texas Instruments) | Same 6-channel SC-70-6 layout; lower capacitance (12 pF), higher clamp voltage (+7.5 V / −1.5 V), higher leakage (500 nA). | Better suited for ultra-high-speed interfaces (>1 Gbps) but less ideal for 5 V logic-level systems due to higher clamp. | Select when signal bandwidth >1 GHz is required and system can tolerate higher clamping voltage. |
| ESD56041D05-2/TR (Will Semiconductor) | 6-channel SC-70-6; identical 30 pF capacitance and 6.1 V stand-off, but rated only to ±15 kV IEC contact discharge. | Cost-optimized alternative where Level 3 (±15 kV) ESD immunity suffices and full Level 4 compliance is not mandated. | Choose for cost-sensitive industrial designs where ±15 kV meets end-equipment certification requirements. |
Compared with TPD6E05U06RTER and ESD56041D05-2/TR, PACDN045YB6-LF delivers balanced performance: industry-leading ±20 kV IEC immunity at 30 pF and low leakage, making it optimal for certified USB/HDMI consumer products where reliability and signal fidelity are co-prioritized.

FAQ
What is the maximum operating temperature range for PACDN045YB6-LF?
The PACDN045YB6-LF is specified for continuous operation from −40 °C to +85 °C, aligning with commercial and extended industrial ambient requirements. This range ensures reliable clamping performance across smartphone, tablet, and industrial controller use cases without thermal derating.
Does PACDN045YB6-LF support unidirectional or bidirectional ESD protection?
PACDN045YB6-LF provides bidirectional ESD protection per channel, with symmetrical clamping behavior: +6.2 V to +6.8 V for positive transients and −0.4 V to −1.2 V for negative transients at ±10 mA. This enables protection of AC-coupled or floating signal lines such as USB D+/D−.
Can PACDN045YB6-LF be used for HDMI 2.0 or higher data rates?
No - PACDN045YB6-LF's 30 pF capacitance is validated for HDMI 1.4 (max 3.4 Gbps) and USB 2.0 (480 Mbps). For HDMI 2.0 (6 Gbps) or USB 3.x, lower-capacitance alternatives (<15 pF) are required; PACDN045YB6-LF is not characterized for those speeds.
Is PACDN045YB6-LF pin-compatible with other members of the PACDN04x family?
No - PACDN045YB6-LF uses SC-70-6 (6-pin), whereas PACDN042YB3R (SC-70-3) and PACDN044YB5R (SC-70-5) have different pin counts and layouts. Pin mapping is unique to each variant; PCB redesign is required when substituting across the PACDN04x family.
What is the GND connection requirement for optimal ESD performance of PACDN045YB6-LF?
PACDN045YB6-LF requires a low-inductance, direct connection from Pin 4 (GND) to the main system ground plane using multiple vias and short traces. High-impedance GND paths degrade clamping speed and increase let-through voltage - verified in IEC 61000-4-2 testing per onsemi's layout guidelines.
