Product details
Overview
ESD7501MUT5G from onsemi is a bi-directional ESD protection diode in X3DFN2 package, featuring 0.45 pF typical junction capacitance, 5 V stand-off voltage, 8.4–9.5 V clamping voltage at 0.5–1.0 A IPP, and IEC 61000-4-2 Level 4 (±16 kV contact) compliance - optimized for high-speed USB 2.0 data lines.
For engineers reviewing the ESD7501MUT5G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance for signal integrity, sub-10 V clamping under 1 A transients, bi-directional symmetry, and 0.60 mm × 0.30 mm footprint for space-constrained interfaces.
Technical Context
The ESD7501MUT5G implements a symmetric bi-directional TVS structure with matched anode-cathode clamping behavior, enabling robust ±8 kV IEC 61000-4-2 ESD suppression on differential or single-ended high-frequency signal paths. Its low dynamic resistance (0.28–0.42 Ω) ensures rapid voltage limiting during fast-rising ESD events.
Designed specifically for <5 V rail protection, it maintains stable reverse leakage (<1.0 µA at 5 V) and exhibits flat capacitance response up to 1 GHz (0.45–0.75 pF), minimizing insertion loss (<0.08 dB @ 1 GHz) critical for USB 2.0 eye diagram integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance (CJ) | 0.45 pF typ @ 0 V, 1 MHz - preserves signal rise time & minimizes distortion on USB 2.0 high-speed (480 Mbps) lines |
| Clamping Voltage (VC) | 8.4 V @ 0.5 A, 9.5 V @ 1.0 A (8/20 µs) - limits transient overvoltage below IC damage thresholds |
| Stand-off Voltage (VRWM) | 5.0 V - matches standard USB 2.0 VBUS and data line DC bias without leakage or conduction |
| ESD Rating | ±16 kV contact per IEC 61000-4-2 Level 4 - exceeds industrial and consumer system-level immunity requirements |
| Package Size | 0.60 mm × 0.30 mm × 0.30 mm - enables placement directly at connector or IC pad with minimal trace stub |
| Dynamic Resistance | 0.28 Ω (Pin1→2), 0.42 Ω (Pin2→1) - ensures consistent clamping performance regardless of ESD polarity |
Pinout & Package
X3DFN2 (Case 152AF) is a 2-terminal, bottom-terminated, leadless micro-package with 0.35 mm pitch, 0.62 mm × 0.32 mm body outline, and 0.24 mm max height - optimized for automated placement and high-density routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (for conventional forward bias) | Bi-directional terminal - functions as cathode when Pin 2 is positive; clamps positive transients to VCC or ground depending on circuit topology |
| Pin 2 | Anode (for conventional forward bias) | Bi-directional terminal - functions as anode when Pin 1 is positive; clamps negative transients symmetrically with Pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.45 pF typ - avoids signal degradation and timing skew on 480 Mbps USB 2.0 differential pairs |
| Bi-directional clamping | Matched VC ≤9.5 V for ±1 A pulses - protects both polarities of transient without external biasing |
| Miniature footprint | 0.60 mm × 0.30 mm - fits within 0.5 mm clearance zones near USB connectors or SoC I/O pads |
| Low dynamic resistance | 0.28–0.42 Ω - reduces voltage overshoot during sub-nanosecond ESD rise times (tR < 1 ns) |
Applications
| USB 2.0 High-Speed Interface | MHL 2.0 Link Protection |
|---|---|
Use Scenario: ESD protection on D+ and D− lines of USB 2.0 host/device ports exposed to user-handling events. IC Role / Device Role / Timing Role: Bi-directional transient voltage suppressor placed between connector and PHY, operating passively with zero latency. Use Value: Maintains <0.5 dB insertion loss at 480 MHz while clamping ±16 kV ESD to <9.5 V - preserving eye opening and bit error rate. | Use Scenario: Protecting MHL 2.0 TMDS channels (up to 3 Gbps) in mobile-to-display docking solutions. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp on each differential pair, placed immediately adjacent to the MHL controller's output pins. Use Value: 0.45 pF capacitance prevents signal integrity loss across 1.5 GHz fundamental frequency - enabling full bandwidth compliance. |
| eSATA Data Lines | Mobile Display Serial Interface |
Use Scenario: Shielding eSATA Gen II (3 Gbps) TX/RX pairs from connector-based ESD in external storage enclosures. IC Role / Device Role / Timing Role: Standalone ESD suppressor mounted at the eSATA receptacle, referenced to chassis ground. Use Value: 5 V VRWM aligns with eSATA common-mode voltage range; 8.4 V VC at 0.5 A prevents PHY latch-up during hot-plug events. | Use Scenario: Protecting MIPI D-PHY or LVDS display serial links in smartphones and tablets against I/O port ESD. IC Role / Device Role / Timing Role: Per-lane ESD clamp on source-synchronous clock and data lanes, placed before EMI filters. Use Value: Sub-10 V clamping and 0.3 mm height allow integration beneath narrow-bezel display flex cables without mechanical interference. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 0.8 pF typical capacitance; 12 V clamping at 1 A; SOT-5X3 (1.0 mm × 0.6 mm) | Larger footprint; higher capacitance limits use to lower-speed interfaces (e.g., UART, I²C) | Select when board space permits larger package and USB 2.0 speed is not required. |
| SP1001-01UTG | 0.35 pF typical capacitance; 10.5 V clamping at 1 A; 0.6 mm × 0.3 mm uDFN | Slightly lower capacitance but higher clamping voltage; RoHS-compliant but not halogen-free | Prefer where sub-0.4 pF is mandatory and 10.5 V VC remains within system margin. |
Compared with TPD2E001DRYR and SP1001-01UTG, the ESD7501MUT5G delivers the optimal balance of ultra-low capacitance (0.45 pF), tight clamping (≤9.5 V), and minimal footprint (0.60 × 0.30 mm) - making it the preferred choice for space- and signal-integrity-critical USB 2.0 implementations.

FAQ
What is the maximum clamping voltage of the ESD7501MUT5G under IEC 61000-4-2 ESD stress?
The ESD7501MUT5G clamps to ≤9.5 V at 1.0 A peak pulse current (8/20 µs waveform), as specified in its Electrical Characteristics table. This value is measured per IEC 61000-4-2 test conditions and reflects worst-case voltage seen by protected circuitry during ±16 kV contact discharge events. The ESD7501MUT5G achieves this with symmetric bi-directional behavior and low dynamic resistance.
Does the ESD7501MUT5G require external biasing or control signals to operate?
No, the ESD7501MUT5G is a passive, bi-directional TVS diode that requires no external bias, power, or control signals. It operates solely based on voltage threshold - conducting only during transient overvoltage events exceeding its 5.0 V stand-off rating. Its zero-bias operation makes integration simple and reliable across all USB 2.0, MHL 2.0, and eSATA designs using the ESD7501MUT5G.
What is the junction capacitance of the ESD7501MUT5G at 1 GHz, and how does it affect USB 2.0 performance?
The ESD7501MUT5G exhibits 0.45–0.75 pF junction capacitance at 1 MHz, and maintains flat response up to 1 GHz per Figure 6 in its datasheet. At 480 MHz (USB 2.0 fundamental), this results in <0.08 dB insertion loss (Figure 5), preserving signal integrity, eye opening, and jitter margin - confirming the ESD7501MUT5G is qualified for full-speed USB 2.0 channel compliance.
Is the ESD7501MUT5G compatible with lead-free reflow soldering processes?
Yes, the ESD7501MUT5G is Pb-free, halogen-free/BFR-free, and RoHS compliant. Its X3DFN2 package supports standard lead-free reflow profiles with a maximum lead solder temperature of 260 °C for 10 seconds, as stated in the Maximum Ratings table. This ensures compatibility with modern SMT assembly lines handling the ESD7501MUT5G.
How is the polarity marked on the ESD7501MUT5G package, and does polarity matter for ESD protection?
The ESD7501MUT5G uses a generic marking "XM" on Pin 1 side (cathode side per conventional diode symbol), but functions identically in either orientation due to its bi-directional design. Polarity assignment is provided for traceability only - the ESD7501MUT5G clamps symmetrically between Pin 1 and Pin 2 regardless of installation direction, eliminating orientation-dependent assembly errors.
