Product details
Overview
ESD5205P6T6G from onsemi is a low-capacitance unidirectional ESD protection diode array in SOT-963 package, rated for 5.0 V reverse working voltage, 9 V clamping voltage at 1 A (8×20 µs), and 9.0 pF junction capacitance - designed to protect high-speed SD card data lines against ±15 kV IEC 61000-4-2 contact ESD events.
For engineers reviewing the ESD5205P6T6G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under IEC-level stress, junction capacitance impact on signal integrity, thermal survivability up to +125°C junction temperature, and Pb-free SOT-963 footprint compatibility with high-density SD connector layouts.
Technical Context
The ESD5205P6T6G implements a monolithic dual-channel unidirectional TVS structure with common-anode configuration, enabling simultaneous protection of two independent I/O lines to ground. Its low 9.0 pF capacitance minimizes signal distortion on SD clock and data lanes operating up to 100 MHz.
Clamping behavior is characterized per IEC 61000-4-2 (±15 kV contact/air) and TLP (±8 A/±16 A), delivering 9–10 V clamping at 1–2 A and ≤15.6 V at 16 A, ensuring robust transient suppression without compromising voltage-sensitive host controller I/O thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 5.0 V - defines maximum continuous DC bias before leakage rise; matches SD card interface supply rails. |
| Clamping Voltage (1 A, 8×20 µs) | 9.0 V - peak voltage seen by protected IC during 1 A surge; stays below typical 12 V I/O absolute max rating. |
| Junction Capacitance | 9.0 pF - measured at 0 V, 1 MHz; enables <1% signal attenuation on 50 Ω SD bus traces up to 100 MHz. |
| ESD Rating (IEC 61000-4-2) | ±15 kV contact / ±15 kV air - exceeds Level 4 immunity requirement; validated per standard test waveform. |
| Peak Pulse Power | 18 W - supports single-event energy dissipation without thermal runaway at TJ ≤ 125°C. |
| Operating Junction Temp | −55°C to +125°C - ensures reliability in automotive infotainment and industrial SD host environments. |
Pinout & Package
SOT-963 (Case 527AD), 1.00 mm × 1.00 mm × 0.37 mm, 0.35 mm pitch, 6-pin ultra-small outline package with exposed pad option not present - optimized for space-constrained SD card slots and microSD adapters.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | Cathode (I/O pins) | Each connects to one protected high-speed line (e.g., SD_CMD, SD_CLK); forward-biased during ESD negative transients. |
| 3, 6 | Anode (common ground) | Internally tied to GND; provides low-inductance return path for all clamped surges - requires solid PCB ground plane connection. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Lower 3.5 pF capacitance but only ±8 kV IEC 61000-4-2 rating; single-channel, requiring two devices for dual-line protection. | Preferred for ultra-high-speed USB 2.0 or MIPI D-PHY where sub-4 pF is mandatory; less suitable for SD interfaces needing ±15 kV robustness. | Select when signal bandwidth >200 MHz dominates over ESD margin; verify layout allows two separate SOT-563 placements. |
| ESD56051D05-7 | Same SOT-963 package and ±15 kV rating, but bidirectional configuration (5.0 V symmetric breakdown); 12 pF capacitance. | Better suited for AC-coupled or floating interfaces like HDMI CEC or I²C; higher capacitance limits use in >50 MHz SD buses. | Choose for mixed-signal lines with undefined DC bias polarity; avoid if SD bus timing budget is constrained by capacitive loading. |
Compared with TPD2E001DRYR and ESD56051D05-7, the ESD5205P6T6G uniquely balances ±15 kV immunity, 9.0 pF capacitance, and dual-unidirectional topology in a single SOT-963 - making it optimal for cost- and space-sensitive SD host designs requiring guaranteed Level 4 compliance without signal integrity trade-offs.

FAQ
What is the maximum clamping voltage of ESD5205P6T6G under IEC 61000-4-2 ±8 kV contact discharge?
The ESD5205P6T6G exhibits clamping voltage ≤10 V under IEC 61000-4-2 ±8 kV contact discharge, as confirmed by oscilloscope waveforms in Figures 1 and 2 of the official datasheet. This value reflects the peak voltage measured across the device terminals during the full ESD pulse event, ensuring protected circuitry remains within safe operating limits. The ESD5205P6T6G achieves this performance through its low dynamic impedance design and optimized silicon process.
Does ESD5205P6T6G support bidirectional signal lines like I²C or USB D+/D−?
No, the ESD5205P6T6G is a unidirectional device configured with common anode - intended for DC-biased lines referenced to ground, such as SD card CMD/CLK. It is not suitable for true bidirectional or AC-coupled interfaces without additional biasing. For I²C or USB, consider bidirectional alternatives like ESD56051D05-7. The ESD5205P6T6G datasheet explicitly specifies I/O-to-GND operation only.
What is the thermal resistance (RθJA) of ESD5205P6T6G in SOT-963 package?
The datasheet does not specify RθJA for ESD5205P6T6G; however, typical SOT-963 devices with similar die size and copper pad exposure achieve ~280°C/W on 1-in² 1-oz copper. For thermal design, rely on the absolute maximum junction temperature rating of +125°C and derate power dissipation using the 18 W peak pulse rating and duty cycle constraints. The ESD5205P6T6G is not intended for continuous power dissipation - its thermal design centers on single-pulse survivability.
Can ESD5205P6T6G be used to protect HDMI or PCIe lanes?
No - the 9.0 pF junction capacitance of ESD5205P6T6G exceeds recommended limits for HDMI 2.0 (>6 Gbps) and PCIe Gen3+ signaling, where sub-0.5 pF is typically required. While electrically functional, it would degrade eye height and increase jitter beyond specification. The ESD5205P6T6G is optimized for lower-frequency interfaces like SD (≤100 MHz) and eMMC (≤200 MHz), not multi-gigabit serial links.
Is ESD5205P6T6G compatible with lead-free reflow soldering profiles?
Yes, ESD5205P6T6G is Pb-free and qualified per JEDEC J-STD-020, supporting peak reflow temperatures up to 260°C for 10 seconds. Its SOT-963 package is rated for MSL Level 1, meaning unlimited floor life at ≤30°C/60% RH - no baking required prior to assembly. The ESD5205P6T6G meets IPC-A-610 Class 2 acceptance criteria when processed using standard lead-free reflow profiles.
