Product details
Overview
PTVS5V0Z1USKN from Nexperia is a unidirectional transient voltage suppressor (TVS) diode in a DSN1608-2 (SOD963) leadless package, designed for ESD and surge protection on low-voltage power rails and signal lines in mobile electronics. It delivers 1200 W peak pulse power (8/20 µs), clamps at ≤18 V under 80 A surge, and exhibits 0.06 Ω dynamic resistance with only 0.25 mm height for ultra-thin PCB integration.
For engineers reviewing the PTVS5V0Z1USKN datasheet, PTVS5V0Z1USKN pinout, PTVS5V0Z1USKN application, or PTVS5V0Z1USKN equivalent, key selection criteria include its 5 V reverse standoff voltage, 1200 W IEC 61000-4-5 compliance, sub-1 pF leakage at 5 V, 1200 pF capacitance at 0 V, and SOD963 footprint compatibility for space-constrained portable designs.
Technical Context
This unidirectional TVS operates as a clamping device between anode and cathode terminals, triggering conduction when reverse voltage exceeds 6.4 V (typical breakdown). Its low dynamic resistance (0.06 Ω) ensures minimal voltage overshoot during fast transients like IEC 61000-4-2 ±30 kV contact discharge.
The DSN1608-2 package enables direct placement adjacent to protected IC pins, minimizing trace inductance. Clamping performance is characterized across two waveforms: 8/20 µs (1200 W, 80 A) for lightning/surge immunity and 10/1000 µs (200 W, 20 A) for longer-duration overvoltage events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 5 V - Maximum continuous operating voltage before clamping begins; matches 5 V logic and USB VBUS rails. |
| Breakdown Voltage (VBR) | 6.4–7.8 V @ 10 mA - Confirmed turn-on threshold ensuring reliable activation above nominal rail voltage. |
| Clamping Voltage (VCL) | ≤18 V @ 80 A, 8/20 µs - Limits downstream IC stress to safe levels during high-energy surges. |
| Peak Pulse Power (PPPM) | 1200 W @ 8/20 µs - Supports robust IEC 61000-4-5 Level 4 (4 kV) system-level surge immunity. |
| Dynamic Resistance (Rdyn) | 0.06 Ω @ 10 A - Enables tight clamping with minimal IR drop, critical for protecting low-voltage SoCs. |
| Diode Capacitance (Cd) | 1200 pF @ 1 MHz, 0 V - Measured value directly impacts high-speed signal integrity; suitable for DC/low-frequency power lines. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - Provides full-system ESD robustness without external shielding. |
Pinout & Package
DSN1608-2 (SOD963) is a 2-terminal, ultra-low-profile (0.25 mm height), leadless surface-mount package measuring 1.6 mm × 0.8 mm. Its compact footprint supports placement directly at connector or IC entry points to minimize inductive loop area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., VBUS or signal); conducts during positive transients when line voltage exceeds VRWM. |
| 2 (A) | Anode | Connected to ground reference; completes clamping path during overvoltage events to shunt current safely to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile packaging | 0.25 mm height enables use in slim smartphones, wearables, and foldable displays where Z-axis space is constrained. |
| High surge capability | 1200 W (8/20 µs) withstands repeated lightning-induced surges per IEC 61000-4-5 without degradation. |
| Low dynamic resistance | 0.06 Ω ensures <1 V additional overshoot beyond VCL during 80 A pulses, preserving margin for 3.3 V/5 V ICs. |
| Low leakage current | 0.025 µA @ 5 V minimizes standby power loss in battery-powered devices with always-on rails. |
| ESD-hardened construction | ±30 kV contact discharge rating eliminates need for secondary ESD protection in USB, SIM, and SD card interfaces. |
Applications
| USB Power Delivery Protection | Mobile Baseband Processor I/O Protection |
|---|---|
Use Scenario: Protecting VBUS and CC lines in USB-C ports against hot-plug surges and cable-induced transients. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between VBUS and GND, activated within nanoseconds of overvoltage detection.

Use Scenario: Safeguarding high-speed GPIO, UART, and I²C lines connected to cellular baseband processors in smartphones. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted at board edge to clamp ESD events before reaching processor pins. Use Value: Maintains signal integrity with 1200 pF capacitance while providing ±30 kV ESD immunity-critical for RF-sensitive baseband domains. |
| Smartphone Battery Charging Circuit | Wearable Device Power Management IC Input |
Use Scenario: Protecting input stage of buck-boost chargers from adapter-induced surges and load-dump transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp on charger IC VIN pin, conducting within 1 ns to divert surge energy to GND. Use Value: Enables use of smaller input capacitors by absorbing 1200 W peaks, reducing BOM cost and PCB area vs. RC snubbers. |
Use Scenario: Securing PMIC input rails in compact wearables (e.g., TWS earbuds) exposed to frequent handling and static discharge. IC Role / Device Role / Timing Role: Space-optimized TVS placed directly at PMIC VIN pad due to 1.6 × 0.8 mm DSN1608-2 footprint. Use Value: Achieves full IEC 61000-4-2 compliance in <2 mm² area-enabling robust power rail protection without compromising miniaturization goals. |
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), 600 W PPPM, 10.8 V VCL @ 10 A | Larger footprint and higher clamping voltage limit suitability to non-portable industrial power supplies | Select when board space allows larger packages and higher clamping voltage is acceptable for 5 V systems. |
| TPD4E05U06DQAR | Quad-channel ESD array in USON-10, 5.5 V VRWM, 12 V VCL @ 4 A, 0.5 pF per channel | Optimized for high-speed data lines (USB 2.0, HDMI), not power rail surge handling | Choose for multi-line signal protection where capacitance <1 pF is mandatory and surge current <10 A suffices. |
Compared with SMAJ5.0A and TPD4E05U06DQAR, PTVS5V0Z1USKN uniquely balances ultra-compact size, 1200 W surge capacity, and 5 V standoff in a single-device solution-making it optimal for mobile power rail protection where space, clamping precision, and surge robustness are jointly constrained.

FAQ
What is the maximum clamping voltage of PTVS5V0Z1USKN under a full 80 A surge?
The clamping voltage is guaranteed ≤18 V when subjected to an 8/20 µs waveform with 80 A peak current, as verified per IEC 61000-4-5 test conditions. This value is measured across pins 1 (K) and 2 (A) at 25 °C ambient and defines the absolute upper voltage seen by downstream circuitry during worst-case surge events.
Can PTVS5V0Z1USKN be used for bidirectional protection?
No-it is a unidirectional TVS diode with cathode (pin 1) and anode (pin 2) terminals, designed only for protection against positive transients on a line referenced to ground. For bidirectional applications such as AC signal lines or differential buses, a dedicated bidirectional TVS like PTVS5V0U1USKN must be selected.
How does the 0.25 mm package height impact thermal performance?
The DSN1608-2 package's 0.25 mm height reduces thermal mass and limits heat spreading area, resulting in higher junction temperature rise per watt compared to larger packages. Derating is required above 85 °C ambient; the datasheet specifies 150 °C max junction temperature and provides thermal resistance curves for layout optimization.
Is PTVS5V0Z1USKN qualified for automotive applications?
No-this device is not AEC-Q200 qualified and lacks automotive-grade screening, temperature range validation (-40 °C to +125 °C ambient is specified but not validated per automotive stress tests), or PPAP documentation. It is intended for consumer mobile applications only.
