Product details
Overview
PTVS30VZ1UPA from Nexperia is a unidirectional transient voltage suppressor diode in DFN2020-3 (SOT1061-3) package, designed to protect single-line DC power or signal paths against IEC 61000-4-5 surges and IEC 61000-4-2 ESD events. It features VRWM = 30 V, IPPM = 150 A (8/20 µs), VCL = 33.5 V (typ.) at 150 A, IRM ≤ 1 µA at 30 V, and Cd = 540 pF at 1 MHz - enabling robust protection in space-constrained portable electronics.
For engineers reviewing the PTVS30VZ1UPA datasheet, PTVS30VZ1UPA pinout, PTVS30VZ1UPA application, or PTVS30VZ1UPA equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, surge current derating at elevated ambient temperature, thermal resistance of the DFN2020-3 footprint, and capacitance impact on high-speed signal integrity.
Technical Context
This unidirectional TVS operates as a clamping device triggered by reverse-biased avalanche breakdown above VBR (31–34.5 V). Its low dynamic impedance ensures rapid voltage limiting during 8/20 µs transients, with measured VCL remaining ≤37 V up to 150 A peak pulse current per IEC 61000-4-5.
The DFN2020-3 package provides low thermal resistance (RθJA ≈ 125 K/W typical on 2-layer PCB) and supports automated reflow assembly. Pin configuration (anode on terminal 3, cathodes on terminals 1 & 2) enables symmetric layout routing and minimizes parasitic inductance in high-current surge paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 30 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets upper limit for protected line's steady-state voltage. |
| VBR | 31–34.5 V at 1 mA - Breakdown onset range; determines minimum overvoltage threshold for clamping activation. |
| VCL | 33.5 V (typ.) at 150 A - Clamped voltage during full-rated surge; must stay below protected IC's absolute max rating with safety margin. |
| IPPM | 150 A - Peak pulse current rating for 8/20 µs waveform; defines maximum surge energy the device can absorb without failure. |
| Cd | 540 pF at 0 V, 1 MHz - Junction capacitance affecting signal rise time and bandwidth; critical for USB, HDMI, or Ethernet line protection. |
| ESD Rating | ±30 kV (IEC 61000-4-2, contact/air) - Confirmed immunity to human-body-model ESD events without degradation. |
Pinout & Package
PTVS30VZ1UPA uses the DFN2020-3 (SOT1061-3) thermally enhanced, leadless plastic package measuring 2.0 × 2.0 × 0.55 mm. Its ultra-thin profile and exposed thermal pad support high-power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Common cathode connection; tied to protected line's positive rail or signal path in unidirectional configuration. |
| 2 | Cathode | Redundant cathode terminal; electrically parallel to Pin 1 to reduce bond wire inductance and improve surge current sharing. |
| 3 | Anode | Ground reference node; connects directly to system GND plane to minimize clamping loop inductance during transient events. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping | Enables protection of DC-biased lines (e.g., 3.3 V/5 V/12 V rails) without forward conduction during normal operation. |
| Ultra-low clamping voltage | VCL = 33.5 V (typ.) at 150 A ensures <12% overvoltage margin above VRWM - critical for safeguarding 30 V-rated downstream components. |
| Low capacitance | 540 pF allows use on medium-speed interfaces (e.g., RS-485, CAN FD, PMBus) without signal distortion or timing skew. |
| High ESD robustness | ±30 kV contact discharge rating meets industrial and medical ESD immunity requirements without external shielding. |
Applications
| Power Supply Input Protection | USB Type-C VBUS Line Protection |
|---|---|
|
Use Scenario: Protecting 24–36 V DC input rails in industrial PLC modules from lightning-induced surges and load dump transients. IC Role / Device Role: Primary clamping element placed between input connector and upstream DC-DC converter input capacitor. Use Value: Limits transient voltage to ≤37 V, preventing damage to 40 V-rated input MOSFETs and reducing need for oversized input capacitors. |
Use Scenario: Safeguarding USB Type-C receptacle VBUS pins against hot-plug spikes and ESD during cable insertion. IC Role / Device Role: Standalone TVS mounted adjacent to connector, shunting surge energy directly to chassis ground. Use Value: 540 pF capacitance avoids violating USB 2.0 eye diagram mask; ±30 kV ESD rating eliminates need for secondary ESD arrays. |
| Automotive Body Control Module (Non-Automotive Qualified) | Industrial Sensor Interface Protection |
|
Use Scenario: Protecting 12 V supply lines in non-safety-critical automotive aftermarket devices (e.g., infotainment add-ons). IC Role / Device Role: Secondary surge suppression stage after primary fuse and LC filter, handling residual transients. Use Value: 150 A surge rating withstands ISO 7637-2 Pulse 1 & 2a waveforms when combined with proper PCB layout and grounding. |
Use Scenario: Shielding analog sensor outputs (e.g., 4–20 mA loop transmitters) from field wiring-induced surges in factory automation. IC Role / Device Role: Low-leakage protector placed at terminal block entry point, minimizing offset error in precision current loops. Use Value: IRM ≤ 1 µA at 30 V prevents measurable error in 24 V loop-powered sensors; DFN2020-3 footprint saves board space in dense I/O modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | DO-214AC package; higher VCL = 48.4 V at 150 A; VRWM = 30 V; Cd = 350 pF | Larger footprint (4.5 × 2.7 mm); lower capacitance but 45% higher clamping voltage | Prefer when board space permits and lower capacitance outweighs clamping margin loss. |
| SMCJ30A | DO-214AB package; VRWM = 30 V; VCL = 48.4 V at 150 A; Cd = 250 pF; IPPM = 150 A | Substantially larger (7.1 × 6.2 mm); better thermal mass but unsuitable for ultra-compact designs | Select only if thermal cycling reliability under repeated surges is prioritized over size and clamping performance. |
Compared with SMAJ30A and SMCJ30A, PTVS30VZ1UPA delivers tighter clamping (33.5 V vs. 48.4 V) and smaller footprint (2.0 × 2.0 mm), making it optimal for space-constrained, high-density layouts where low-voltage margin and fast transient response are critical - though its higher capacitance requires verification in >10 Mbps data lines.

FAQ
What is the maximum operating temperature for PTVS30VZ1UPA?
The junction temperature (Tj) must not exceed 125 °C under continuous operation. Ambient temperature range is –40 °C to +125 °C, with thermal performance dependent on PCB copper area and airflow. Derating curves in the datasheet show 150 A surge capability drops to ~110 A at Tamb = 85 °C due to thermal saturation.
Can PTVS30VZ1UPA be used for bidirectional protection?
No - PTVS30VZ1UPA is strictly unidirectional. Its pinout (dual cathodes, single anode) and V-I characteristics support clamping only for positive transients relative to ground. For bidirectional protection, two devices in series-opposed configuration or a dedicated bidirectional TVS like PTVS30VU1UPA must be used.
How does the dual-cathode pinout affect PCB layout?
Pins 1 and 2 are internally shorted cathodes; routing both to the same net reduces inductance in the surge current path and improves current sharing during fast transients. Layout best practice is to connect them with wide, low-inductance traces directly to the protected line, avoiding vias between pins.
Is PTVS30VZ1UPA automotive qualified?
No - this device is not AEC-Q200 qualified or tested for automotive environments. Nexperia explicitly states in the legal disclaimers that non-automotive-qualified products are unsuitable for safety-critical vehicle systems. Use only in industrial, consumer, or aftermarket applications with appropriate risk assessment.
