Product details
Overview
CM6100 from onsemi is a 2-channel, 4-bump wafer-level chip-scale package (WLCSP4) ESD protection device with 1.5 pF typical channel input capacitance, ±8 kV contact/±15 kV air IEC 61000-4-2 compliance, and clamp voltage of +9.8 V (positive) / −1.5 V (negative) at 1 A transient current - deployed in high-speed USB 2.0 and HDMI interface protection.
For engineers reviewing the CM6100 datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance matching (≤0.02 pF), dual-channel ground-shared layout, WLCSP4 mechanical compatibility, and IEC 61000-4-2 Level 4 robustness for portable electronics front-end protection.
Technical Context
The CM6100 integrates two independent bidirectional ESD protection channels in a monolithic silicon die, each featuring low-leakage diode clamping with dynamic resistance of 0.7 Ω (positive) and 0.5 Ω (negative) at 1 A. It operates across −40 °C to +85 °C and supports 3.0–5.5 V supply rails without biasing circuitry.
Its 0.4 mm pitch, 0.8 mm × 0.8 mm WLCSP4 package uses solder bumps (A1, A2, B1, B2) with coplanarity ≤0.05 mm and conforms to RoHS II. The device requires no external components and functions as a passive, unidirectional clamping structure per channel referenced to shared ground terminals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±8 kV contact / ±15 kV air per IEC 61000-4-2 Level 4 - ensures survivability against common human-body ESD events in handheld devices. |
| Channel Capacitance | 1.5 pF typical at 1 MHz, 0 V bias - preserves signal integrity for USB 2.0 (480 Mbps) and HDMI 1.4 differential pairs. |
| Capacitance Matching | ≤0.02 pF max mismatch between channels - critical for balanced high-speed differential line protection. |
| Clamp Voltage | +9.8 V / −1.5 V at 1 A, 8/20 µs pulse - limits transient overvoltage to safe levels for 3.3 V/5 V interface ICs. |
| Leakage Current | ±0.30 µA max at 3 V - avoids DC loading on sensitive analog or high-impedance data lines. |
| Package | WLCSP4 (0.8 mm × 0.8 mm, 0.4 mm pitch, CASE 567CB) - enables ultra-compact PCB placement adjacent to connectors. |
Pinout & Package
CM6100 uses a 4-bump WLCSP4 package (CASE 567CB) with bottom-side solder bumps. Dimensions: 0.8 mm × 0.8 mm, pitch 0.4 mm, coplanarity ≤0.05 mm. Orientation marked via laser etch on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | ESD Channel 1 Anode/Cathode | Primary I/O terminal for first protected signal line; bidirectionally clamps to ground during ESD transients. |
| A2 | ESD Channel 2 Anode/Cathode | Primary I/O terminal for second protected signal line; electrically isolated but shares ground path with A1. |
| B1 & B2 | Device Ground | Two dedicated ground bumps - reduce inductance and improve transient return path for both channels. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance matching | 0.02 pF max inter-channel capacitance mismatch - maintains phase alignment in differential signaling paths. |
| Dual-channel integrated ground | Two separate ground bumps (B1, B2) with low-inductance connection - minimizes ground bounce during simultaneous ESD events. |
| IEC 61000-4-2 Level 4 compliance | Validated ±8 kV contact / ±15 kV air discharge - meets industrial and consumer end-equipment immunity requirements. |
| RoHS II compliant WLCSP | Pb-free solder bumps, halogen-free dielectric - satisfies EU environmental directives without derating performance. |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Lines |
|---|---|
Use Scenario: Protection of D+ and D− pins on USB 2.0 host/device ports against electrostatic discharge during cable insertion or handling. IC Role / Device Role / Timing Role: Passive bidirectional ESD clamp placed directly at connector, before PHY transceiver. Use Value: 1.5 pF capacitance prevents signal rise-time degradation; matched channels preserve differential skew under ESD stress. | Use Scenario: Safeguarding HDMI DDC (I²C) and CEC control lines from user-touch ESD in AV receivers and set-top boxes. IC Role / Device Role / Timing Role: Low-leakage (±0.3 µA) shunt protector enabling reliable I²C clock/data communication up to 400 kHz. Use Value: −1.5 V negative clamp voltage avoids forward-biasing downstream I²C pull-up networks during ESD events. |
| Mobile Display Serial Interface | Automotive Infotainment Touchscreen |
Use Scenario: ESD hardening of MIPI D-PHY data lanes (CLKP/CLKN, DATAP/DATAN) in smartphone display modules. IC Role / Device Role / Timing Role: Dual-channel CSP device mounted adjacent to flex connector to minimize trace length and inductance. Use Value: 0.8 mm × 0.8 mm footprint allows placement within 1 mm of connector - critical for <10 mm trace routing. | Use Scenario: Protecting resistive/capacitive touchscreen controller I/Os (X+, X−, Y+, Y−) in automotive-grade infotainment panels. IC Role / Device Role / Timing Role: Dual-channel ESD suppressor rated for −40 °C to +85 °C operation, qualified per AEC-Q101 stress tests. Use Value: +9.8 V positive clamp voltage ensures downstream touchscreen ASIC inputs remain below absolute maximum ratings during ESD. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Single-channel, 1.0 pF typical capacitance, SOT-5X3 package (1.0 mm × 1.0 mm) | Requires two devices for dual-line protection; larger footprint and higher parasitic inductance than WLCSP4 | Preferred when board space permits discrete placement and lower capacitance is prioritized over integration. |
| ESD5Z3.3T5G | Single-channel, 3.3 V working voltage, 1.8 pF capacitance, SOD-523 package | Higher capacitance and no channel matching spec; not validated for differential pair use | Suitable for cost-sensitive single-line protection where 1.5 pF matching is non-critical. |
Compared with TPD2E001DRYR and ESD5Z3.3T5G, the CM6100 uniquely delivers dual-channel integration, sub-0.02 pF capacitance matching, and WLCSP4 footprint - making it optimal for space-constrained, high-speed differential interfaces requiring matched transient response.

FAQ
What is the operating temperature range for the CM6100?
The CM6100 operates across −40 °C to +85 °C, validated per Table 2 in the official datasheet. This range supports deployment in consumer portable electronics and industrial control panels. The CM6100 maintains specified leakage current (±0.30 µA max), capacitance (1.5 pF typ), and clamp voltage (+9.8 V / −1.5 V) within this full range without derating.
Does the CM6100 require external biasing or power supply connections?
No, the CM6100 is a passive, diode-based ESD protection device with no power supply pins. It functions solely through intrinsic PN junction clamping between I/O (A1/A2) and ground (B1/B2) terminals. The CM6100 draws zero quiescent current and imposes no DC loading on protected lines - ideal for always-on sensor or interface circuits.
How is the CM6100 mechanically mounted on PCBs?
The CM6100 uses a 4-bump WLCSP4 package with solder balls on the bottom surface (CASE 567CB). It is reflow-soldered face-down onto PCB pads matching the 0.4 mm pitch layout. The recommended soldering footprint is 0.40 mm × 0.40 mm per bump, with stencil aperture design per onsemi's SOLDERRM/D manual. The CM6100 does not require underfill or adhesive anchoring for standard thermal cycling profiles.
Can the CM6100 protect both positive and negative ESD transients?
Yes, the CM6100 provides bidirectional clamping: +9.8 V clamp for positive transients and −1.5 V for negative transients at 1 A (8/20 µs), per Table 3. Its symmetrical internal structure enables equal protection polarity without external circuitry. This behavior is intrinsic to the CM6100's monolithic silicon design and verified per IEC 61000-4-2 testing protocol.
Is the CM6100 compatible with lead-free assembly processes?
Yes, the CM6100 is Pb-free and qualified for standard lead-free reflow profiles (J-STD-020, peak 260 °C). Its WLCSP4 package uses SAC305-compatible solder bumps and meets RoHS II Directive 2011/65/EU. The CM6100's thermal performance and mechanical reliability have been validated through onsemi's lead-free qualification testing, including thermal cycling and drop shock.
