Product details
Overview
CM1213-06MR 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 compact MSOP-8 packages.
For engineers reviewing the CM1213-06MR 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 CM1213-06MR implements a dual-diode steering architecture per channel-each I/O pin connects to both VP (positive rail) and VN (ground rail) via series diodes-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).
Channel capacitance remains stable across temperature and bias voltage due to optimized junction design, with mutual capacitance of only 0.11 pF between adjacent signal pins-critical for differential high-speed signaling integrity in USB2.0 and DVI applications where 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 compliance without additional board-level protection components. |

| Capacitance Matching | 0.02 pF typical between channels-supports precise differential pair routing in HDMI and DVI interfaces. |
| Mutual Capacitance | 0.11 pF typical between adjacent pins-reduces crosstalk-induced jitter in tightly spaced high-speed traces. |
| Clamp Voltage (Positive) | +8.8 V at 1 A, 8/20 µs pulse-limits voltage overshoot on protected lines during ESD events. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 6, 8 | CH1–CH6 | ESD-protected I/O channels-each connects to VP and VN via internal steering diodes for bidirectional transient suppression. |
| 3 | VN | Negative supply rail (GND)-serves as return path for negative ESD pulses and reference for Zener clamp operation. |
| 7 | VP | Positive supply rail (PWR)-clamped by integrated Zener to limit positive transients and stabilize rail during ESD events. |
Key Features
| Feature | Design Value |
|---|---|

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 | 0.35 pF typical capacitance; lower clamping voltage (+6.5 V); SOT-23-6 package | Better suited for sub-100 Mbps interfaces where ultra-low capacitance outweighs rail-clamp functionality | Select SP1006-06UTG when minimizing signal loading is critical and external rail decoupling is already present |
| TPD2E001DRYR | 1.0 pF capacitance; no integrated VP-VN Zener; requires external 0.1 µF VP bypass capacitor | Requires additional PCB area and component for rail stabilization-less optimal for space-constrained USB ports | Choose TPD2E001DRYR only if legacy layout lacks VP-Zener integration and external capacitor placement is feasible |
Compared with SP1006-06UTG and TPD2E001DRYR, the CM1213-06MR uniquely combines 1.0 pF capacitance with self-contained VP-VN Zener clamping-reducing component count and layout complexity for USB2.0/HDMI designs requiring both low loading and rail stability.

FAQ
What is the maximum operating voltage range for the CM1213-06MR?
The CM1213-06MR supports an operating supply voltage range of VP–VN = 3.3 V to 5.5 V, with absolute maximum ratings up to 6.0 V. This allows direct integration into standard 3.3 V USB2.0, 5 V FireWire, and 3.3 V HDMI systems without level-shifting circuitry. The CM1213-06MR's Zener diode is rated to clamp transients within this range while maintaining stable rail voltage during ESD events.
Does the CM1213-06MR require an external bypass capacitor on the VP pin?
No-the CM1213-06MR integrates a Zener diode between VP and VN that clamps supply rail transients, eliminating the need for an external 0.22 µF bypass capacitor in most applications. This reduces BOM cost and PCB area. However, for lowest possible clamp voltage under heavy transient loads, a 0.22 µF ceramic capacitor placed close to the VP pin is still recommended per the datasheet's design guidelines. The CM1213-06MR's architecture enables this flexibility.
How many ESD strikes can the CM1213-06MR withstand per I/O pin?
The CM1213-06MR is rated to withstand over 1000 ±8 kV contact discharge ESD strikes per I/O pin under IEC 61000-4-2 Level 4 test conditions-verified with 1-second intervals and continuous 1000-pulse testing. Post-test validation confirms all electrical parameters remain within specification. This endurance makes the CM1213-06MR suitable for high-mating-cycle interfaces like USB ports and removable storage connectors.
What is the channel-to-channel capacitance matching specification for the CM1213-06MR?
The CM1213-06MR provides 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 consistent signal propagation delay and impedance balance-critical for differential signaling in HDMI and DVI applications. The CM1213-06MR's matched capacitance minimizes skew-induced eye closure in high-speed serial links.
Which package type does the CM1213-06MR use, and what are its key mechanical dimensions?
The CM1213-06MR uses the MSOP-8 package (JEDEC MO-187 compliant, Case 846AD), measuring 3.0 mm × 3.0 mm × 1.1 mm with 0.65 mm lead pitch. Its compact footprint and exposed pad variant support high-density PCB layouts in portable electronics. The CM1213-06MR's pinout is fully compatible with SOIC-8 footprints for layout flexibility, though thermal performance differs due to smaller body size and lower 400 mW power rating.
