Product details
Overview
TVS8501V5MUT5G from onsemi is a unidirectional transient voltage suppressor diode designed for I/O line ESD protection in high-speed digital interfaces. It features a 5.0 V working peak reverse voltage (VRWM), 7.0 V typical breakdown voltage (VBR) at 1 mA, 11.5 V clamping voltage at 70 A (8/20 µs), 16 pF junction capacitance at 0 V, and operates across −65 °C to +150 °C. It is used in USB 2.0, HDMI, and portable audio data lines to prevent damage from IEC 61000−4−2 ±30 kV contact discharge.
For engineers reviewing the TVS8501V5MUT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping performance under 70 A lightning surge (IEC 61000−4−5), low 16 pF capacitance for signal integrity preservation, UDFN2 package compatibility with space-constrained layouts, and verified ±30 kV ESD robustness per IEC 61000−4−2 Level 4.
Technical Context
This unidirectional TVS diode employs a planar silicon avalanche structure optimized for fast response (<1 ns) to ESD transients and low dynamic resistance (0.04 Ω). Its clamping behavior is characterized by a well-defined knee at ~6.0 V and stable voltage limiting up to 70 A peak pulse current under 8/20 µs waveform conditions.
The device is rated for bidirectional ESD testing (pin 1–2 and 2–1), supports 0 V DC bias operation, and exhibits minimal capacitance variation (16 pF at 0 V, <10 pF at 3 V), making it suitable for 480 Mbps USB 2.0 signaling without signal distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous reverse voltage before leakage exceeds 0.1 µA; sets upper limit for safe DC bias in protected data lines. |
| VBR (min/typ/max) | 6.0 / 7.0 / 9.0 V @ 1 mA - Ensures reliable turn-on before system IC damage threshold; typical 7.0 V enables margin against 5.5 V rail overvoltage. |
| VC @ 70 A | 11.5 V - Clamped voltage during full IEC 61000−4−5 70 A surge; keeps downstream ICs below absolute maximum ratings. |
| Junction Capacitance | 16 pF @ 0 V - Low enough to avoid signal rise-time degradation in USB 2.0 (480 Mbps) and HDMI 1.4a applications. |
| ESD Rating | ±30 kV contact discharge (IEC 61000−4−2 Level 4) - Validated protection level for handheld consumer electronics interface ports. |
| Package | UDFN2 (1.6 mm × 1.0 mm, 0.4 mm height) - Enables placement directly at connector entry point with minimal PCB area and inductance. |
Pinout & Package
TVS8501V5MUT5G is housed in a 2-terminal UDFN2 package (Case 517CZ), with Pin 1 designated as Cathode and Pin 2 as Anode. The compact 1.6 mm × 1.0 mm footprint supports high-density routing and low-inductance placement adjacent to connectors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode) | Protected Line Connection (Anode of internal avalanche diode) | Connected to the signal line requiring ESD protection; reverse-biased during normal operation; conducts during positive transients. |
| Pin 2 (Anode) | Ground Reference Terminal | Connected to system ground plane; completes conduction path during ESD events; requires low-impedance ground return for effective clamping. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000−4−2 Level 4 ESD Protection | ±30 kV contact discharge validated - eliminates need for secondary board-level shielding in consumer port designs. |
| Low Dynamic Resistance | 0.04 Ω - Minimizes voltage overshoot during fast-rising ESD pulses, improving clamping consistency across multiple strikes. |
| Ultra-Low Capacitance | 16 pF at 0 V - Preserves signal edge rate and eye diagram integrity in high-speed differential interfaces like USB 2.0. |
| Pb-Free, Halogen-Free/BFR-Free | RoHS-compliant construction - Meets global environmental compliance requirements without compromising surge performance. |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Channels |
|---|---|
|
Use Scenario: Protecting D+ and D− lines in portable USB peripherals against user-handling ESD events. IC Role / Device Role: Unidirectional shunt clamp placed between signal line and ground, activated only during positive transients. Use Value: 16 pF capacitance avoids signal integrity loss at 480 Mbps; 11.5 V clamping ensures connected PHY stays within 12 V absolute max rating. |
Use Scenario: Safeguarding HDMI Display Data Channel (DDC) and Consumer Electronics Control (CEC) pins from hot-plug ESD. IC Role / Device Role: Standalone TVS diode mounted at HDMI receptacle, providing low-capacitance protection without loading 5 V DDC pull-up. Use Value: 5.0 V VRWM matches DDC logic high level; ±30 kV ESD rating exceeds IEC test requirement for display interface ports. |
| Smartphone Audio Jacks | Industrial Sensor Interface Lines |
|
Use Scenario: ESD protection for analog audio paths (MIC, HP_L/R) exposed via 3.5 mm TRRS jacks in mobile handsets. IC Role / Device Role: Unidirectional clamp suppressing positive transients while preserving DC bias and low-noise analog performance. Use Value: 0.1 µA leakage at 5 V prevents DC offset shift; 16 pF avoids high-frequency attenuation in 20 kHz audio band. |
Use Scenario: Protecting RS-485 or CAN FD transceiver I/O pins in factory automation nodes subject to cable-induced surges. IC Role / Device Role: First-line transient suppressor upstream of transceiver, handling IEC 61000−4−5 70 A lightning surges. Use Value: 11.5 V clamping at 70 A limits stress on transceiver's ±12 V fault tolerance; UDFN2 allows placement near connector. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package (4.5 mm × 2.7 mm); 5.0 V VRWM; 13.4 V VC @ 70 A; 100 pF capacitance | Higher clamping voltage and capacitance; suited for power rail or lower-speed signal lines where layout space permits | Select when board space allows larger package and higher capacitance is acceptable; not suitable for USB 2.0 or HDMI. |
| TPD2E001DRYR | 2-channel, 0.8 pF per line, 5.5 V VRWM, 12 V VC @ 1 A; 6-pin UQFN; integrated dual-diode array | Lower capacitance but lower surge rating (1 A IPP); intended for ESD-only, not lightning-grade protection | Choose for ultra-high-speed interfaces needing sub-1 pF loading; use TVS8501V5MUT5G when 70 A IEC 61000−4−5 compliance is required. |
Compared with SMAJ5.0A and TPD2E001DRYR, TVS8501V5MUT5G uniquely balances 70 A surge capability, 11.5 V clamping, and 16 pF capacitance in a 1.6 mm × 1.0 mm UDFN2 package-enabling single-device protection for speed-critical, space-constrained I/O lines requiring both ESD and lightning immunity.
