Product details
Overview
CM1216-06MR from onsemi is a 6-channel low-capacitance ESD protection array designed for high-speed data lines, featuring 1.6 pF typical channel input capacitance, ±15 kV IEC 61000-4-2 ESD protection per channel, and mutual capacitance of 0.13 pF - deployed in HDMI, USB2.0, and Serial ATA interfaces where minimal signal distortion is critical.
For engineers reviewing the CM1216-06MR datasheet, pinout, applications, or equivalent options, key selection criteria include channel count (6), MSOP-8 package footprint, leakage current (±1.0 µA max), clamp voltage (+9.0 V / −1.5 V at 1 A), and supply voltage range (3.3 V to 5.5 V).
Technical Context
The CM1216-06MR implements a dual-diode steering architecture per channel, routing ESD transients to VP (positive rail) or VN (negative rail) with dynamic resistance of 0.6 Ω (positive) and 0.4 Ω (negative) at 1 A. It operates within −40°C to +85°C ambient and supports up to 6 V VP–VN differential supply.
Each I/O pin withstands over 1000 ESD strikes, and capacitance matching between channels is tightly controlled at 0.04 pF typical - critical for differential signaling integrity in DVI and HDMI applications where skew must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection Level | ±15 kV per IEC 61000-4-2 contact discharge - ensures robust system-level immunity without external clamping components |
| Channel Input Capacitance | 1.6 pF typical at 1 MHz - preserves signal integrity on >480 Mbps USB2.0 and 1.65 Gbps DVI links |
| Mutual Capacitance | 0.13 pF typical - minimizes crosstalk between adjacent high-speed lanes in multi-channel ports |
| Clamp Voltage (Positive) | +9.0 V at 1 A, 8/20 µs pulse - limits transient overvoltage to safe levels for 3.3 V or 5 V I/O buffers |
| Clamp Voltage (Negative) | −1.5 V at 1 A, 8/20 µs pulse - prevents negative excursion below ground that could damage CMOS inputs |
| Supply Voltage Range | 3.3 V to 5.5 V VP–VN - compatible with standard logic supply rails and backward-compatible with legacy 5 V systems |
| Leakage Current | ±1.0 µA max at 5 V - avoids DC loading errors in precision analog or high-impedance sensor interfaces |
Pinout & Package
CM1216-06MR is housed in an 8-pin MSOP package (Case 846AD), measuring 3.0 mm × 3.0 mm × 0.8 mm with 0.65 mm pitch - optimized for space-constrained portable electronics PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CH1–CH6 | I/O | 6 bidirectional ESD protection channels; each connects to a data line (e.g., HDMI TMDS+, DVI D0+, USB D+, etc.) |
| VN | GND | Negative supply rail connection; must be tied directly to system ground plane with low-inductance path |
| VP | PWR | Positive supply rail connection; requires local 0.22 µF ceramic bypass capacitor to ground for optimal clamping |
Key Features
| Feature | Design Value |
|---|---|
| Low Channel Capacitance | 1.6 pF typical enables use on 480 Mbps USB2.0 and 1.65 Gbps DVI without measurable eye diagram degradation |
| Tight Capacitance Matching | 0.04 pF typical difference between channels maintains timing skew <10 ps in differential pairs |
| High ESD Endurance | Withstands >1000 ±15 kV ESD strikes - extends field life in frequently connected consumer ports |
| Thermal Robustness | 400 mW package power rating supports sustained surge handling without thermal runaway in compact enclosures |
| Pb-Free & RoHS Compliant | Meets global environmental compliance requirements for consumer electronics and industrial equipment |
Applications
| HDMI/DVI Interfaces | USB2.0 Ports |
|---|---|
Use Scenario: Protecting TMDS differential pairs in notebook video outputs and digital TV receivers against connector-based ESD events. IC Role / Device Role / Timing Role: Bidirectional ESD clamp placed immediately after HDMI/DVI connectors, before signal conditioning ICs. Use Value: 0.13 pF mutual capacitance prevents inter-pair crosstalk; 1.6 pF loading avoids 3% eye height reduction at 1.65 Gbps. | Use Scenario: Safeguarding upstream/downstream data lines in portable storage devices and docking stations during hot-plug insertion. IC Role / Device Role / Timing Role: Per-lane ESD protection on D+ and D− lines, with VP tied to 3.3 V USB PHY supply. Use Value: ±15 kV contact ESD rating meets IEC 61000-4-2 Level 4; 0.04 pF capacitance matching preserves USB2.0 differential skew tolerance. |
| Serial ATA Interfaces | PCI Express Lanes |
Use Scenario: Shielding SATA II (3 Gbps) differential signals in SSD modules and laptop motherboard traces from ESD-induced bit errors. IC Role / Device Role / Timing Role: Dual-channel protection per SATA lane (TX+/TX−), mounted within 5 mm of edge connector. Use Value: 0.6 Ω positive dynamic resistance ensures clamp voltage stays ≤9.0 V under 1 A ESD pulse - below SATA receiver absolute max rating. | Use Scenario: Adding board-level ESD resilience to PCIe Gen1 x1/x4 slots in embedded computing platforms without altering signal layer stackup. IC Role / Device Role / Timing Role: One CM1216-06MR protects six PCIe lanes (e.g., two x1 + one x4 configuration) using shared VP/VN rails. Use Value: 400 mW MSOP-8 thermal rating allows simultaneous clamping across multiple lanes during multi-pin ESD events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD6E05U06RTER | 6-channel, 0.5 pF typical capacitance, lower clamp voltage (+6.5 V / −1.2 V), but rated only to ±12 kV IEC 61000-4-2 | Better for ultra-high-speed (>5 Gbps) SerDes; insufficient for full Level 4 ESD immunity in consumer HDMI ports | Select when sub-1 pF loading is mandatory and ESD threat level is ≤±12 kV |
| SP3206-01UTG | 6-channel, 1.8 pF typical capacitance, ±15 kV rating, but higher dynamic resistance (1.2 Ω positive) and no mutual capacitance spec | Suitable for cost-sensitive industrial I/O where minor signal degradation is acceptable | Choose for legacy designs requiring drop-in replacement with relaxed crosstalk requirements |
Compared with TPD6E05U06RTER and SP3206-01UTG, the CM1216-06MR uniquely balances ±15 kV immunity, 1.6 pF loading, and 0.13 pF mutual capacitance - making it optimal for HDMI 1.3/1.4 and USB2.0 applications demanding both robustness and signal fidelity.

FAQ
What is the maximum operating temperature for the CM1216-06MR?
The CM1216-06MR supports an ambient operating temperature range of −40°C to +85°C, with a junction temperature limit of −40°C to +125°C. This makes CM1216-06MR suitable for deployment in consumer electronics such as notebooks and set-top boxes where internal board temperatures may rise significantly under sustained operation.
Does the CM1216-06MR require external biasing or control signals?
No, the CM1216-06MR is a passive ESD protection device requiring only VP and VN connections to the system's positive and negative supply rails - no enable pins, control logic, or external voltage references are needed. The CM1216-06MR functions autonomously upon ESD event detection via its integrated diode steering network.
Can the CM1216-06MR protect differential signal pairs like HDMI TMDS or USB D+/D−?
Yes, the CM1216-06MR is explicitly validated for differential high-speed interfaces: each CHx pin protects one signal line, and its 0.04 pF channel-to-channel capacitance mismatch ensures <10 ps skew between paired lines. The CM1216-06MR is referenced in onsemi application notes for HDMI 1.3/1.4 and USB2.0 implementations.
What is the recommended PCB layout practice for the CM1216-06MR?
Place the CM1216-06MR within 3 mm of the protected connector, route I/O traces directly to CHx pins with minimum stub length, connect VP to a local 0.22 µF ceramic capacitor tied to ground, and tie VN directly to the main ground plane using multiple vias - all to minimize parasitic inductance that degrades clamp performance. These practices are specified in the CM1216-06MR datasheet layout guidelines.
Is the CM1216-06MR compliant with RoHS and lead-free soldering standards?
Yes, the CM1216-06MR is Pb-free and RoHS compliant, packaged in an MSOP-8 (Case 846AD) with matte tin lead finish. It supports reflow soldering per J-STD-020 moisture sensitivity level 1, and onsemi provides full process compatibility documentation for lead-free assembly in the CM1216-06MR packaging specification BRD8011/D.
