Product details
Overview
CM1263-02SE from onsemi is a dual-channel low-capacitance ESD protection diode array designed for high-speed serial interfaces including MIPI, MDDI, and MPL. It delivers 0.85 pF typical channel capacitance, ±8 kV contact/±15 kV air IEC 61000-4-2 ESD protection, and operates from 3.3 V to 5.5 V supply across –40°C to +85°C.
For engineers reviewing the CM1263-02SE datasheet, pinout, applications, or equivalent options, key selection criteria include channel-to-channel capacitance matching (ΔCIN ≤ 0.02 pF), dynamic resistance (RDYN ≤ 0.96 Ω positive / ≤ 0.5 Ω negative), and clamp voltage performance (VCL = +9.96 V / –1.6 V at 1 A).
Technical Context
The CM1263-02SE integrates two independent bidirectional ESD protection channels in a single SOT-553 package, each featuring low-leakage silicon diodes with controlled forward voltage (VF ≤ 0.80 V at 8 mA) and tight input capacitance matching. Its VP/VN supply rails enable biasing of internal protection structures without external components.
Designed specifically for signal integrity–sensitive mobile interfaces, it maintains sub-1 pF loading per channel while meeting Level 4 IEC 61000-4-2 requirements. The NC pin (Pin 3) provides mechanical stability and thermal relief but carries no electrical function.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 2 independent ESD protection paths for differential or parallel high-speed data lines |
| Capacitance (CIN) | 0.85 pF typical per channel - preserves signal integrity on >500 Mbps MIPI D-PHY links |
| ESD Rating | ±8 kV contact / ±15 kV air per IEC 61000-4-2 Level 4 - meets industrial handheld robustness requirements |
| Clamp Voltage (VCL) | +9.96 V (positive) / –1.6 V (negative) at 1 A - limits transient overvoltage during ESD events |
| Leakage Current (ILEAK) | ≤1.0 µA at 5 V - avoids DC loading on low-power camera/LCD data lines |
| Supply Range (VP–VN) | 3.3 V to 5.5 V - compatible with standard mobile I/O voltage domains |
Pinout & Package
CM1263-02SE uses the 5-pin SOT-553 package (Case 463B), measuring 1.60 mm × 1.20 mm × 0.55 mm with 0.50 mm pitch. Pin 1 (VP) and Pin 2 (VN) provide bias rails; Pins 4 and 5 serve as protected I/O terminals; Pin 3 is no-connect.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VP) | Positive supply rail | Bias voltage input for top diode anodes; sets clamping threshold for positive transients |
| 2 (VN) | Negative supply rail | Bias voltage return for bottom diode cathodes; defines reference for negative transient clamping |
| 3 (NC) | No-connect | Mechanical anchor and thermal pad; must remain unconnected to avoid parasitic coupling |
| 4 (CH1) | Channel 1 I/O terminal | Protected data line input/output - connects directly to MIPI DSI/CSI lane or MDDI data pair |
| 5 (CH2) | Channel 2 I/O terminal | Second protected data line - enables dual-lane protection without discrete devices |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel integration | Reduces PCB area by 40% vs. two discrete 0402 TVS diodes while maintaining matched trace routing |
| 0.85 pF typical CIN | Enables clean eye diagrams on 1.5 Gbps MIPI D-PHY v1.2 links without equalization |
| 0.02 pF ΔCIN matching | Minimizes skew between differential pairs in camera sensor interfaces |
| ±8/±15 kV IEC 61000-4-2 | Qualifies for drop-in replacement in certified wireless handset designs without retesting |
| Pb-free & RoHS compliant | Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1) for standard SMT assembly |

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, 0.5 pF CIN, 5-pin SOT-553, same VP/VN bias architecture | Requires two units for dual-lane protection; lower capacitance but higher BOM count | Select when ultra-low 0.5 pF loading is prioritized over space efficiency |
| ESD56081D05 | Dual-channel, 0.9 pF CIN, 6-pin SOT-563, no VP/VN bias rails - uses grounded-cathode configuration | Eliminates need for bias supply but increases footprint and reduces clamping precision | Select when system lacks dedicated VP/VN rails and board area permits 6-pin layout |
Compared with TPD2E001DRYR and ESD56081D05, the CM1263-02SE uniquely balances dual-channel integration, 0.85 pF loading, and active bias control - enabling optimal signal integrity and ESD margin in space-constrained MIPI designs without external components.

FAQ
What is the maximum operating temperature range for the CM1263-02SE?
The CM1263-02SE is rated for continuous operation from –40°C to +85°C, aligning with extended industrial temperature requirements for mobile handset and portable electronics applications. This range is validated per the Absolute Maximum Ratings table and confirmed in the Electrical Operating Characteristics section of the official datasheet.
Does the CM1263-02SE require external bias components?
No, the CM1263-02SE does not require external bias components. Its VP and VN pins accept a 3.3 V to 5.5 V supply to internally bias the protection diodes. When properly connected, this eliminates the need for pull-up/pull-down resistors or capacitors typically used with passive ESD arrays.
Can the NC pin (Pin 3) be grounded or left floating?
Pin 3 is a true no-connect terminal with no internal connection. It must remain unconnected - neither grounded nor tied to any voltage - to prevent unintended parasitic coupling or thermal stress. The datasheet explicitly states its role as mechanical and thermal support only.
How does the CM1263-02SE achieve ±15 kV air discharge protection with only 0.85 pF capacitance?
The CM1263-02SE achieves ±15 kV air discharge protection through optimized silicon geometry and precise doping profiles in its integrated diode structure - not via added capacitance. Its low CIN results from minimized junction area and shallow diffusion depth, while ESD robustness stems from controlled avalanche breakdown and low dynamic resistance (RDYN ≤ 0.96 Ω).
Is the CM1263-02SE compatible with lead-free reflow soldering processes?
Yes, the CM1263-02SE is Pb-free and RoHS compliant, qualified for standard lead-free reflow profiles per J-STD-020. Its SOT-553 package supports peak temperatures up to 260°C, and the device is rated MSL1 - meaning it may be stored indefinitely at ambient conditions without baking prior to assembly.
