Product details
Overview
PESD3V3X4UHMYL from Nexperia is a 4-channel unidirectional ESD protection array in a DFN1308-6 (SOT8006B) package, designed for SD-card interface lines. It delivers 25 kV IEC 61000-4-2 contact ESD immunity, 3.7 V typical clamping voltage at 11 A (8/20 µs), and 0.15 Ω dynamic resistance-enabling robust transient suppression in portable SD-card slots.
For engineers reviewing the PESD3V3X4UHMYL datasheet, PESD3V3X4UHMYL pinout, PESD3V3X4UHMYL application, or PESD3V3X4UHMYL equivalent, key selection criteria include reverse standoff voltage (3.3 V), low diode capacitance (0.8–0.9 pF), common-anode 4-diode architecture, and ultra-thin 0.38 mm profile for space-constrained SD card connectors.
Technical Context
This device implements four independent unidirectional TVS diodes sharing two common anode terminals (Pins 2 and 5), enabling compact protection of four unidirectional signal lines-such as SD_CMD, SD_CLK, SD_DAT0, and SD_DAT1-against both positive and negative transients. Its TLP-characterized Rdyn = 0.15 Ω ensures minimal voltage overshoot during fast ESD events.
The 3.3 V VRWM rating aligns with 3.3 V SD-card signaling, while VBR ≥ 5 V (at 1 mA) provides margin against false triggering. Clamping performance is validated per IEC 61000-4-5 (8/20 µs surge) and IEC 61000-4-2 (±8 kV contact), with sub-4.5 V VCL across full 11 A pulse range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V - Matches 3.3 V SD-card I/O voltage; prevents leakage or conduction during normal operation. |
| VCL @ 11 A | 3.7 V typ. - Limits transient voltage to safe level below SD-card absolute maximum ratings (typically 3.6 V). |
| ESD Rating | ±25 kV IEC 61000-4-2 - Exceeds industrial and consumer ESD immunity requirements for handheld devices. |
| Cd @ 0 V | 0.8–0.9 pF - Minimizes signal distortion on high-speed SD-card data lines (up to 104 MB/s UHS-I). |
| Rdyn | 0.15 Ω - Ensures rapid energy shunting with low residual voltage during nanosecond-scale ESD events. |
| Package | DFN1308-6 (SOT8006B), 1.3 × 0.8 × 0.38 mm - Enables placement directly at SD-card connector with minimal PCB footprint. |
Pinout & Package
DFN1308-6 (SOT8006B) is a leadless, extremely thin surface-mount package with 6 terminals, 1.3 mm × 0.8 mm body size, and 0.38 mm max height-optimized for ultra-thin portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode, diode 1) | Connects to first protected line (e.g., SD_CMD); cathode ties to signal, anode to common reference. |
| 2 | CA (common anode, diode 1–2) | Shared anode node for diodes 1 and 2; connects to ground or local reference plane. |
| 3 | K2 (cathode, diode 2) | Connects to second protected line (e.g., SD_CLK); forms unidirectional clamp with Pin 2. |
| 4 | K3 (cathode, diode 3) | Connects to third protected line (e.g., SD_DAT0); pairs with Pin 5 anode. |
| 5 | CA (common anode, diode 3–4) | Shared anode node for diodes 3 and 4; electrically isolated from Pin 2 for layout flexibility. |
| 6 | K4 (cathode, diode 4) | Connects to fourth protected line (e.g., SD_DAT1); completes 4-line protection set. |
Key Features
| Feature | Design Value |
|---|---|
| 4-line unidirectional topology | Enables discrete protection of SD_CMD, SD_CLK, SD_DAT0, SD_DAT1 without bidirectional compromise or capacitance penalty. |
| 0.15 Ω dynamic resistance | Reduces clamping voltage overshoot under fast-rising ESD pulses (<1 ns rise time), improving system-level immunity margin. |
| 0.8–0.9 pF diode capacitance | Preserves signal integrity on 50 MHz SD clock and high-speed data lanes; avoids timing skew or eye closure. |
| 25 kV ESD rating | Meets and exceeds IEC 61000-4-2 Level 4 (±8 kV contact / ±15 kV air) for end-product certification. |
| Ultra-thin 0.38 mm profile | Allows integration beneath SD-card connectors in <1.0 mm Z-height mobile designs (e.g., tablets, wearables). |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional multi-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | Quad unidirectional; 3.3 V VRWM; higher VCL = 5.5 V @ 12 A; larger SOT-563 package (2.1 × 1.25 mm). | Higher clamping increases risk of SD host IC damage; larger footprint limits placement near ultra-compact connectors. | Select only if board space permits and 5.5 V clamping is acceptable for target host IC VDDIO tolerance. |
| Vishay VEML6040-GS08 | Not applicable - optical ambient light sensor; misidentified as ESD part in some cross-reference tools. | Functionally incompatible; no ESD protection capability. | Avoid - this is not a valid alternative; confirmed non-equivalent via Vishay product matrix and datasheet review. |
Compared with NUP4201MR6T1G, PESD3V3X4UHMYL offers 1.8 V lower clamping and 55 % smaller footprint-critical for modern SD-card layouts-while VEML6040-GS08 is unrelated and must be excluded from ESD protection consideration.

FAQ
What is the maximum continuous reverse voltage this device can withstand?
The PESD3V3X4UHMYL has a reverse standoff voltage (VRWM) of 3.3 V, meaning it blocks up to 3.3 V DC or steady-state AC signals without conducting. This matches standard 3.3 V SD-card I/O voltage levels and ensures zero leakage current under normal operation, as confirmed by IRM ≤ 100 nA at VRWM.
Can this device protect bidirectional SD data lines like DAT0–DAT3?
No-PESD3V3X4UHMYL is strictly unidirectional and protects only signals referenced to ground with defined polarity (e.g., SD_CMD, SD_CLK). For true bidirectional SD data lines, a separate bidirectional array such as PESD5V0X1BL is required; mixing unidirectional and bidirectional protection on the same bus is not supported.
How does the dual-common-anode pinout (Pins 2 and 5) affect PCB layout?
The split common anode design (Pin 2 for K1/K2, Pin 5 for K3/K4) allows independent grounding of two signal groups-reducing shared-impedance coupling and enabling optimized return path routing. Each CA pin must connect directly to a low-inductance ground plane via dedicated vias, not daisy-chained traces.
Is this device qualified for automotive applications?
No-PESD3V3X4UHMYL is specified for industrial and consumer use only. It lacks AEC-Q200 qualification and is not rated for automotive temperature ranges (−40 °C to +125 °C). For automotive SD-card interfaces, Nexperia's Automotive Qualified PESDxVxYx series (e.g., PESD5V0X1BLA) must be used instead.
