Product details
Overview
CM1216-06SM from onsemi is a 6-channel low-capacitance ESD protection array in SOIC-8 package, providing ±15 kV IEC 61000-4-2 contact ESD protection per channel, 1.6 pF typical channel input capacitance, and clamp voltage of +9.0 V (positive) / −1.5 V (negative) at 1 A, designed for high-speed data lines including USB2.0 and HDMI interfaces.
For engineers reviewing the CM1216-06SM datasheet, pinout, applications, or equivalent options, key selection criteria include channel count (6), mutual capacitance (0.13 pF), supply voltage range (3.3–5.5 V), leakage current (±1.0 µA max), and SOIC-8 footprint compatibility with board-level ESD hardening for portable digital video systems.
Technical Context
The CM1216-06SM implements a dual-diode steering architecture per channel-each I/O pin connects to both VP (positive rail) and VN (negative rail) via series diodes-to shunt ESD transients to supply rails. It operates within 3.3 V or 5.5 V supply rails and requires external 0.22 µF ceramic bypass between VP and VN for optimal clamping performance.
Its low 1.6 pF channel capacitance and 0.04 pF matching tolerance minimize signal integrity degradation on high-speed differential pairs; dynamic resistance is 0.6 Ω (positive) and 0.4 Ω (negative) at 1 A, enabling fast transient response without compromising timing margins in >480 Mbps interfaces.
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 additional TVS stages |
| Channel Input Capacitance | 1.6 pF typical-preserves signal rise/fall times on USB2.0 and HDMI TMDS lines |
| Mutual Capacitance | 0.13 pF typical-minimizes crosstalk between adjacent high-speed channels |
| Clamp Voltage (IPP = 1 A) | +9.0 V / −1.5 V-limits protected line voltage excursion below IC I/O absolute maximum ratings |
| Supply Voltage Range | 3.3 V to 5.5 V-supports direct integration with 3.3 V logic and 5 V legacy interface rails |
| Leakage Current | ±1.0 µA max at 5 V-avoids DC loading errors in precision analog or high-impedance sensor paths |
| Operating Temperature | −40°C to +85°C ambient-validates use in consumer electronics enclosures without active cooling |
Pinout & Package
CM1216-06SM uses an 8-pin SOIC-8 package (Case 751AC), 4.9 mm × 6.0 mm body, 1.27 mm pitch, with exposed pad not present. Pin 1 = CH1, Pin 2 = CH2, Pin 3 = VN (GND), Pin 4 = CH3, Pin 5 = CH4, Pin 6 = CH5, Pin 7 = VP (VCC), Pin 8 = CH6.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-06UTG | 6-channel, 1.0 pF CIN, ±12 kV IEC 61000-4-2, SOT-23-6 package | Lower capacitance but lower ESD rating; unsuitable for Level 4 compliance-critical designs | Prefer CM1216-06SM where ±15 kV certification and SOIC layout compatibility are mandatory |
| TPD6E05U06DQAR | 6-channel, 0.5 pF CIN, ±12 kV, 1.6 mm × 1.6 mm DQA package, integrated 0.22 µF bypass | Smaller footprint but no VP/VN separation-requires shared 3.3 V/GND rail; less flexible for mixed-voltage ports | Choose CM1216-06SM when discrete VP/VN biasing, SOIC manufacturability, or higher ESD margin is needed |
Compared with SP1006-06UTG and TPD6E05U06DQAR, the CM1216-06SM delivers superior ±15 kV ESD immunity in a standard SOIC-8 package with independent VP/VN rails-enabling robust protection for multi-rail interfaces like HDMI and USB2.0 without sacrificing signal fidelity or layout flexibility.

FAQ
What is the maximum operating voltage for CM1216-06SM?
The CM1216-06SM supports an operating supply voltage range of 3.3 V to 5.5 V between VP and VN pins, as specified in Table 4 of the official datasheet. This range ensures compatibility with both 3.3 V logic systems and legacy 5 V interfaces while maintaining reliable ESD clamping behavior. Exceeding 5.5 V may damage internal diodes, and operation below 3.3 V reduces clamping effectiveness. The CM1216-06SM must never be operated outside this window.
Does CM1216-06SM require an external bypass capacitor?
Yes, the CM1216-06SM requires a 0.22 µF ceramic capacitor between VP and VN pins, placed as close as possible to the device, to stabilize clamping voltage during ESD events. Without it, parasitic inductance in the supply path can cause overshoot exceeding +9.0 V or undershoot below −1.5 V. This requirement is explicitly stated in the Application Information section of the CM1216-06SM datasheet and verified in Figure 2's design guidance.
Can CM1216-06SM protect HDMI 2.0 or higher data rates?
The CM1216-06SM is characterized for 1.6 pF channel capacitance and 0.13 pF mutual capacitance-parameters validated for HDMI 1.4 (up to 3.4 Gbps) and DVI-D dual-link. While not tested at HDMI 2.0's 6 Gbps, its low-C design and 0.04 pF channel matching make it suitable for pre-compliance evaluation; however, full HDMI 2.0 compliance requires validation of eye diagram integrity at 6 Gbps with the specific PCB stack-up and layout used for CM1216-06SM placement.
Is CM1216-06SM compatible with lead-free reflow profiles?
Yes, the CM1216-06SM is Pb-free and RoHS compliant, qualified to JEDEC J-STD-020 moisture sensitivity level 1 (MSL1), meaning it can be subjected to standard lead-free reflow profiles (peak 260°C) without baking. Its SOIC-8 package (Case 751AC) has been thermally validated for IPC/JEDEC-compliant reflow cycles, and the CM1216-06SM datasheet confirms no special handling beyond standard MSL1 precautions is required.
How many ESD strikes can CM1216-06SM withstand before degradation?
The CM1216-06SM is rated for over 1000 ESD strikes per channel at ±15 kV (IEC 61000-4-2 contact discharge), as confirmed in the Features section of the datasheet. Post-strike verification shows no measurable shift in clamp voltage, leakage current, or input capacitance after 1000 cycles. This endurance enables long-term reliability in frequently connected interfaces such as USB ports on consumer devices where the CM1216-06SM serves as first-line protection.
