Product details
Overview
CM1213-06SM from onsemi is a 6-channel low-capacitance ESD protection array designed for high-speed data lines, featuring 1.0 pF typical channel input capacitance, ±8 kV IEC 61000-4-2 contact discharge rating, and integrated VP-VN Zener clamping to eliminate external bypass capacitors. It protects USB2.0, HDMI, and Serial ATA interfaces in SOIC-8 packages.
For engineers reviewing the CM1213-06SM datasheet, pinout, applications, or equivalent options, this device delivers verified low-capacitance ESD protection with matched channel capacitance (0.02 pF typical), minimal voltage-dependent capacitance drift, and robust 1000-strike endurance per I/O pin under IEC level 4 stress.
Technical Context
The CM1213-06SM implements a dual-diode steering architecture per channel-each I/O pin connects via series diodes to VP (positive rail) and VN (ground rail)-enabling bidirectional ESD current diversion. Its embedded Zener diode between VP and VN actively clamps supply rail transients and suppresses inductive overshoot during fast-rising ESD events (e.g., 30 A in 1 ns).
Designed for signal integrity preservation, it maintains tight channel-to-channel capacitance matching (0.02 pF typical) and ultra-low mutual capacitance (0.11 pF typical between adjacent pins), making it suitable for differential high-speed protocols including USB2.0 and HDMI where skew and crosstalk must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±8 kV contact discharge per IEC 61000-4-2 Level 4 - ensures system-level immunity without external TVS augmentation |
| Channel Input Capacitance | 1.0 pF typical at 1 MHz - preserves signal integrity up to 480 Mbps USB2.0 and 1.65 Gbps DVI/HDMI |
| Capacitance Matching | 0.02 pF typical between channels - enables precise differential timing in paired signal lines |
| Mutual Capacitance | 0.11 pF typical between adjacent signal pins - reduces crosstalk-induced jitter in dense port layouts |
| Clamp Voltage (VCL) | +8.8 V (positive), −1.4 V (negative) at 1 A, 8/20 µs - limits protected line excursion below IC I/O absolute max ratings |
| Supply Voltage Range | 3.3 V to 5.5 V VP–VN - supports both 3.3 V logic systems and mixed-voltage board designs |
| Operating Temp | −40 °C to +85 °C - qualified for industrial and consumer endpoint environments |
Pinout & Package
CM1213-06SM is housed in an 8-lead SOIC-8 package (Case 751AC), Pb-free and RoHS-compliant, with 1.27 mm pitch and exposed pad not present. The package supports standard reflow profiles and provides mechanical stability for automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 6, 8 | CH1–CH6 I/O | ESD-protected signal inputs; each steers ±ESD current to VP or VN rails via internal diode pairs |
| 3 | VN | Negative supply rail connection (GND); serves as return path for negative ESD pulses and bias reference |
| 7 | VP | Positive supply rail connection (PWR); clamped by integrated Zener to limit rail bounce during positive ESD strikes |
Key Features
| Feature | Design Value |
|---|---|
| Zener-integrated rail clamping | Eliminates need for external 0.22 µF VP–GND capacitor in most layouts, reducing BOM count and PCB area |
| 1.0 pF typical input capacitance | Enables use on 480 Mbps USB2.0 and 1.65 Gbps DVI links without measurable insertion loss degradation |
| 0.02 pF channel capacitance matching | Supports clean differential signaling in HDMI TMDS pairs by minimizing skew-induced eye closure |
| 0.11 pF mutual capacitance | Reduces inter-pair crosstalk in multi-lane ports (e.g., SATA x2, PCIe x1), preserving signal fidelity |
| 1000+ ESD strike endurance | Validated per IEC61000-4-2 Level 4 (±8 kV contact) - ensures long-term reliability in field-deployed peripherals |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 2-channel, 0.8 pF typical capacitance, no integrated VP–VN Zener; requires external 0.1 µF bypass cap | Limited to dual-line protection; unsuitable for 6-line ports without parallel devices | Preferred only when ultra-low capacitance (<0.85 pF) is mandatory and board space allows external capacitor placement |
| SP1002-06UTG | 6-channel, 0.6 pF typical capacitance, ±12 kV ESD rating, but higher dynamic resistance (1.2 Ω vs. 0.7 Ω) | Better ESD margin but higher clamp voltage (+12.5 V) risks violating 3.3 V I/O abs-max limits | Select when system-level ESD test margin exceeds ±8 kV and supply rail clamping is handled externally |
Compared with TPD2E001DRYR and SP1002-06UTG, the CM1213-06SM uniquely balances 6-channel integration, Zener-enabled rail clamping, and 1.0 pF capacitance-making it optimal for compact, self-contained USB2.0/HDMI port protection without layout compromises.

FAQ
What is the maximum operating voltage for the CM1213-06SM?
The CM1213-06SM supports an operating supply voltage range of 3.3 V to 5.5 V between VP and VN pins. Its absolute maximum rating is 6.0 V VP–VN. Exceeding this may cause permanent damage. The device is rated for continuous operation across −40 °C to +85 °C ambient temperature, and its electrical characteristics-including clamp voltage and leakage-are specified within this range. Always verify VP–VN bias matches system rail voltage before deployment.
Does the CM1213-06SM require an external bypass capacitor on the VP pin?
No-the CM1213-06SM integrates a Zener diode between VP and VN that clamps supply rail transients, eliminating the need for an external bypass capacitor in most applications. This feature reduces BOM count and PCB footprint. However, for lowest possible clamp voltage-especially when VP is biased significantly below the Zener breakdown voltage-a 0.22 µF ceramic capacitor between VP and ground is recommended per the datasheet's layout guidance.
How many ESD strikes can the CM1213-06SM withstand on each channel?
The CM1213-06SM is validated to withstand over 1000 ±8 kV contact discharge ESD strikes per I/O pin under IEC 61000-4-2 Level 4 test conditions. Each pin is subjected to 1000 pulses at 1-second intervals in a single continuous test run. Post-test verification confirms all electrical parameters remain within specification. This endurance rating applies individually to CH1 through CH6 and is independent of simultaneous multi-pin stressing.
What is the channel-to-channel capacitance matching specification for the CM1213-06SM?
The CM1213-06SM exhibits 0.02 pF typical channel input capacitance matching across all six channels at 1 MHz, VP = 3.3 V, VN = 0 V, and VIN = 1.65 V. This tight matching ensures minimal skew between differential signal pairs-critical for HDMI TMDS, USB2.0, and other high-speed protocols where timing alignment directly impacts eye diagram integrity and bit error rate.
Is the CM1213-06SM pin-compatible with other members of the CM1213 family?
The CM1213-06SM uses an 8-lead SOIC-8 package with pinout identical to the CM1213-06MR (MSOP-8 variant), sharing the same CH1–CH6, VN, and VP assignments. However, it is not pin-compatible with the 10-lead CM1213-08MR (8-channel MSOP-10), which adds CH7 and CH8. Layout reuse is possible between SM and MR 6-channel variants, but routing must accommodate SOIC-8 vs. MSOP-8 footprint differences.
