Product details
Overview
PTVS3V3D1BAL from Nexperia is a bidirectional transient voltage suppressor in DFN1006-2 (SOD882) package, designed to protect single-line interfaces against ESD (up to ±30 kV) and surge transients (34 A, 8/20 µs), with reverse standoff voltage of 3.3 V, clamping voltage of 10.3 V (typ.), and dynamic resistance of 0.1 Ω (TLP). It is used in audio interface protection for portable consumer devices.
For engineers reviewing the PTVS3V3D1BAL datasheet, PTVS3V3D1BAL pinout, PTVS3V3D1BAL application, or PTVS3V3D1BAL equivalent, key selection criteria include bidirectional clamping performance, ultra-low capacitance (65–78 pF), AEC-Q101 qualification, and compact 1.0 × 0.6 mm footprint for space-constrained PCB layouts.
Technical Context
This device implements a dual-cathode, bidirectional TVS structure-two back-to-back Zener-like junctions sharing a common anode node-enabling symmetrical clamping for both positive and negative transients on a single line. Its low Rdyn (0.1 Ω) ensures minimal voltage overshoot under high di/dt surge conditions.
It operates within a -55 °C to +150 °C ambient range, supports IEC 61000-4-2 (±30 kV contact/air) and IEC 61000-4-5 (34 A, 8/20 µs) compliance, and delivers stable clamping down to VRWM = 3.3 V with <0.1 nA leakage at rated standoff.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V - Maximum continuous reverse voltage before significant leakage; ensures compatibility with 3.3 V logic and supply rails. |
| VBR (IR = 1 mA) | 4.5 V min - Breakdown initiates reliably above system operating voltage, preventing false triggering during normal operation. |
| VCL (IPPM = 34 A) | 10.3 V typ. - Clamped voltage during worst-case surge; keeps protected ICs below absolute maximum ratings. |
| Cd (f = 1 MHz, VR = 0 V) | 65–78 pF - Low signal-line capacitance preserves integrity of high-speed audio and data interfaces. |
| Rdyn (TLP, 10 A) | 0.1 Ω - Minimal dynamic impedance limits voltage rise during fast ESD events (e.g., <1 ns rise time). |
| ESD Rating | ±30 kV (IEC 61000-4-2) - Full immunity to human-body-model discharges without degradation. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress. |
Pinout & Package
DFN1006-2 (SOD882) is a leadless, ultra-compact surface-mount package measuring 1.0 mm × 0.6 mm × 0.48 mm with 0.65 mm pitch and exposed copper pad for thermal dissipation. The device has no anode terminal exposed externally; both pins are cathodes referenced to a shared internal anode node.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to one side of protected bidirectional line; forms first Zener junction with internal anode. |
| 2 | K2 (Cathode 2) | Connects to opposite side of same line; forms second Zener junction, enabling symmetric clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection | Enables single-device protection of AC-coupled or bipolar signal lines (e.g., headphone jack, USB D+/D−) without polarity constraints. |
| Ultra-low dynamic resistance | 0.1 Ω (TLP) minimizes clamping voltage overshoot during sub-100 ns ESD pulses, critical for protecting sensitive analog front-ends. |
| Low diode capacitance | 65–78 pF avoids signal distortion or bandwidth reduction in audio paths up to 20 kHz and high-speed digital interfaces. |
| AEC-Q101 qualification | Validates robustness across automotive temperature (-55 °C to +150 °C), humidity, and mechanical stress requirements. |
| DFN1006-2 footprint | 1.0 × 0.6 mm body enables placement directly at connectors or ports, reducing PCB trace inductance and improving transient suppression efficacy. |
Applications
| Smartphone Audio Jack Protection | Automotive Infotainment Line Protection |
|---|---|
|
Use Scenario: Protecting 3.5 mm TRRS audio jack signals (MIC, GND, L/R) from user-hand ESD events during plug insertion/removal. IC Role / Device Role / Timing Role: Bidirectional clamping element placed immediately adjacent to jack connector, shunting ESD current to ground before reaching codec IC. Use Value: Prevents latch-up or permanent damage in audio codecs by limiting clamped voltage to ≤10.3 V while maintaining <78 pF loading on analog paths. |
Use Scenario: Safeguarding LIN bus or auxiliary audio input lines in head unit systems exposed to load-dump and jump-start transients. IC Role / Device Role / Timing Role: Primary surge clamp on unidirectional or bidirectional low-speed communication lines interfacing with external sensors or displays. Use Value: AEC-Q101 qualification ensures operational stability over full automotive temperature range; 34 A surge rating handles ISO 7637-2 Pulse 5a/b energy. |
| USB-C Sideband Use (SBU) Protection | Portable Tablet Battery Line Clamp |
|
Use Scenario: Protecting SBU1/SBU2 pins in USB-C receptacles-low-speed, bidirectional, non-power pins susceptible to ESD during cable mating. IC Role / Device Role / Timing Role: Standalone TVS placed at connector edge, with minimal trace length to preserve signal integrity and ESD response speed. Use Value: 65 pF capacitance avoids degrading SBU signal timing; ±30 kV ESD rating exceeds USB-IF compliance thresholds for end-user durability. |
Use Scenario: Clamping voltage spikes on lithium-ion battery feed lines caused by hot-plug events or charger switching noise in tablets and power banks. IC Role / Device Role / Timing Role: Reverse-standoff protector between battery terminal and PMIC input, blocking surge propagation into power management circuitry. Use Value: 3.3 V VRWM matches typical battery monitor reference levels; low leakage (<50 nA) prevents parasitic drain during long-term storage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZ1.5SMC3.3A | Unidirectional, DO-214AB package (4.5 × 3.5 mm), higher VCL (11.2 V), higher Cd (>100 pF) | Suitable only for DC-biased lines; unsuitable for AC-coupled audio or USB SBU due to polarity constraint and size | Select only when board space allows larger footprint and signal polarity is fixed. |
| Vishay SMAJ3.3A | Unidirectional, SMA package (4.5 × 2.7 mm), 30 A IPP, VCL = 9.8 V, Cd ≈ 200 pF | Larger size and higher capacitance limit use in high-frequency or space-sensitive designs; lacks AEC-Q101 certification | Prefer for industrial non-automotive applications where cost outweighs size and qualification requirements. |
Compared with SZ1.5SMC3.3A and SMAJ3.3A, PTVS3V3D1BAL uniquely combines bidirectionality, AEC-Q101 qualification, sub-1 mm² footprint, and <78 pF capacitance-making it the only option qualified for compact, automotive-grade, AC-coupled interface protection.

FAQ
What is the maximum peak pulse current this device can handle?
The PTVS3V3D1BAL is rated for 34 A peak pulse current under IEC 61000-4-5 8/20 µs waveform conditions, verified per datasheet Table 1 and Table 5. This value represents the maximum non-destructive surge level the device sustains without parametric shift or failure, measured at Tamb = 25 °C with proper PCB thermal relief.
Is this device suitable for protecting high-speed USB 2.0 data lines?
No-while its 65–78 pF capacitance is low for audio, it exceeds recommended limits (<2–3 pF) for full-speed USB 2.0 differential signaling. It is appropriate for low-speed, bidirectional lines like USB-C SBU, audio jacks, or LIN bus, but not for D+/D− data pairs requiring minimal capacitive loading.
How does the dual-cathode configuration enable bidirectional protection?
The internal structure connects two Zener-like junctions anode-to-anode, with Pin 1 and Pin 2 serving as separate cathodes. When either pin goes positive relative to the other, its junction avalanches, clamping voltage symmetrically in both directions-enabling protection of AC-coupled or floating lines without polarity assumptions.
Does the marking code 'J5' correspond to the full part number?
Yes-the marking 'J5' on the top surface of the DFN1006-2 package is the manufacturer-assigned code for PTVS3V3D1BAL, as confirmed in Table 4 of the datasheet. It is not a generic identifier and maps exclusively to this device variant, including its 3.3 V VRWM and bidirectional configuration.
