Product details
Overview
PTVS22VZ1USK from Nexperia is a unidirectional transient voltage suppressor (TVS) diode in a leadless DSN1608-2 (SOD964) package, designed for ESD and surge protection on low-voltage power rails and signal lines in space-constrained mobile devices. It delivers 22 V reverse standoff voltage, 37 A rated peak pulse current (8/20 µs), 200 W peak pulse power (10/1000 µs), 0.17 Ω dynamic resistance, and clamps to ≤43.5 V at 37 A - enabling robust protection of USB, SIM card, and battery charging interfaces.
For engineers reviewing the PTVS22VZ1USK datasheet, PTVS22VZ1USK pinout, PTVS22VZ1USK application, or PTVS22VZ1USK equivalent, key selection criteria include its ultra-low 0.29 mm height, bidirectional ESD rating (±30 kV contact/air), sub-200 nA leakage at 22 V, and verified clamping performance under IEC 61000-4-2/4-5/61643-321 waveforms.
Technical Context
This unidirectional TVS operates as a clamping device between anode (Pin 2) and cathode (Pin 1), activating above 24.4 V breakdown voltage to divert transients away from downstream ICs. Its low dynamic resistance (0.17 Ω) ensures minimal voltage overshoot during fast 8/20 µs surges, while the 247 pF capacitance at 0 V bias maintains signal integrity on high-speed lines like USB 2.0.
The DSN1608-2 package enables placement directly at board-level entry points - such as connectors or switches - minimizing trace inductance and maximizing protection efficacy. Thermal design leverages its 150 °C max junction temperature and compatibility with standard reflow profiles per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 22 V reverse standoff voltage - blocks normal operating voltage while remaining non-conductive up to rated system rail. |
| VBR | 24.4–26.9 V breakdown voltage at 10 mA - defines precise turn-on threshold for transient clamping. |
| VCL (8/20 µs) | ≤43.5 V clamping voltage at 37 A - limits stress on protected ICs during lightning-induced surges. |
| Rdyn | 0.17 Ω dynamic resistance - reduces clamping voltage rise under high-current transients. |
| Cd | 247 pF diode capacitance at 1 MHz / 0 V - compatible with USB 2.0 (480 Mbps) and audio interface routing. |
| ESD Rating | ±30 kV per IEC 61000-4-2 - protects against human-body-model discharges without degradation. |
| Package | DSN1608-2 (SOD964), 1.6 × 0.8 × 0.29 mm - fits within tight PCB real estate near connectors and ports. |
Pinout & Package
DSN1608-2 is a 2-terminal, leadless surface-mount package with cathode marked by a bar on the top surface. Dimensions: 1.6 mm length × 0.8 mm width × 0.29 mm height. Compatible with standard reflow soldering per J-STD-020, using footprint per Figure 15 (solder pad width 0.7 mm, length 0.93 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground or lower-potential rail; polarity-sensitive terminal defining unidirectional conduction path. |
| 2 | Anode (A) | Connected to protected line (e.g., VBUS, SIM_DATA); conducts surge current toward ground when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.29 mm height - enables integration beneath mechanical shields and in ultra-thin smartphone bezels. |
| High ESD immunity | ±30 kV contact/air discharge - eliminates need for secondary ESD stages in portable designs. |
| Precision clamping | Clamps to ≤43.5 V at 37 A (8/20 µs) - ensures safe operation of 3.3 V/5 V logic and PMICs. |
| Low leakage | ≤200 nA at 22 V - prevents battery drain in always-on mobile subsystems (e.g., RTC, wake-up circuits). |
| Thermal robustness | 150 °C max junction temperature - supports operation in thermally dense mobile SoC modules. |
Applications
| USB Interface Protection | SIM Card Slot Protection |
|---|---|
|
Use Scenario: Protecting USB 2.0 data lines and VBUS supply against ESD events during cable insertion and hot-plug operations. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed at connector edge to shunt transients before reaching USB transceiver or PMIC. Use Value: 247 pF capacitance preserves signal integrity at 480 Mbps; ±30 kV ESD rating meets IEC 61000-4-2 compliance without additional filtering. |
Use Scenario: Safeguarding SIM card detection and data lines from user-handling ESD and inductive switching noise in smartphones and wearables. IC Role / Device Role / Timing Role: Standoff protector on SIM_VCC and SIM_IO lines, activated only during overvoltage events to avoid loading normal operation. Use Value: 22 V VRWM matches typical SIM supply rails; sub-200 nA leakage prevents battery depletion during standby mode. |
| Battery Charging Circuit Protection | Mobile Display Power Rail Protection |
|
Use Scenario: Clamping voltage spikes on battery input (VBAT) caused by charger hot-swap or load-dump conditions in portable power management systems. IC Role / Device Role / Timing Role: Primary surge limiter between charging IC output and battery terminal, absorbing 200 W pulses per IEC 61643-321. Use Value: 200 W peak pulse power (10/1000 µs) handles sustained energy from charger IC faults; 0.17 Ω Rdyn minimizes clamping overshoot. |
Use Scenario: Protecting AMOLED display power supplies (e.g., AVDD, VGH) from ESD coupling through flex cables and touch controller interfaces. IC Role / Device Role / Timing Role: Point-of-load TVS mounted adjacent to display connector to reduce inductive loop area and improve transient response. Use Value: 0.29 mm height allows placement under display flex assembly; 22 V VRWM aligns with common display bias rail voltages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PTVS22VZ1US,115 | Same die, tape-and-reel packaging variant (no suffix 'K'); identical electrical specs and DSN1608-2 footprint. | No functional difference; used interchangeably in automated SMT lines requiring different reel orientation or labeling. | Select when standard reel logistics (not K-suffix marked reels) are required for production line compatibility. |
| SMAJ22A | DO-214AC package (4.5 × 2.7 × 2.2 mm); higher VBR (24.4–26.9 V same), but 5× larger footprint and 2.2 mm height. | Not suitable for mobile PCBs with height constraints; better suited for industrial power supplies where thermal mass matters more than size. | Choose only if board layout cannot accommodate DSN1608-2 dimensions and higher clamping voltage (53.3 V @ 37 A) is acceptable. |
Compared with PTVS22VZ1USK, PTVS22VZ1US,115 offers identical protection in standard tape format, while SMAJ22A trades miniaturization for higher thermal capacity - making the former ideal for high-volume mobile manufacturing and the latter for cost-sensitive industrial designs where space is not constrained.

FAQ
What is the maximum clamping voltage of PTVS22VZ1USK under IEC 61000-4-5 surge conditions?
The maximum clamping voltage is 43.5 V at 37 A with an 8/20 µs current waveform, measured per IEC 61000-4-5. This value is confirmed in Table 6 of the datasheet under VCL conditions for IPPM = 37 A, ensuring reliable protection of 3.3 V and 5 V ICs during lightning-induced surges.
Can PTVS22VZ1USK be used for bidirectional signal line protection?
No - PTVS22VZ1USK is a unidirectional TVS diode, configured with anode and cathode terminals. It protects only against positive transients on the anode relative to cathode. For bidirectional protection (e.g., USB D+/D−), a dedicated bidirectional TVS such as PTVS3V3S1UR must be used instead.
What is the thermal resistance (RθJA) of the DSN1608-2 package?
The datasheet does not specify RθJA for PTVS22VZ1USK. However, its 150 °C maximum junction temperature and 125 °C ambient rating imply suitability for standard PCB layouts with minimal copper pour; thermal performance is validated via JEDEC JESD51-2 compliant testing in the original qualification report.
Is PTVS22VZ1USK automotive qualified?
No - this part is not AEC-Q200 qualified and is explicitly designated for mobile consumer applications. Nexperia's datasheet states "Non-automotive qualified products" in Section 13, and no automotive test reports or qualification data are included in the 2017 product data sheet.
