Product details
Overview
PTVS3V3Z1BSC from Nexperia is a bidirectional transient voltage suppressor (TVS) diode in a DSN1006-2 (SOD993B) package, designed for ESD and surge protection of single bidirectional signal or power lines. It delivers 30 kV IEC 61000-4-2 contact ESD immunity, clamps at 11 V (typ.) under 70 A 8/20 µs surge, and maintains 3.3 V reverse standoff voltage - deployed in audio interfaces and battery supply lines of portable consumer electronics.
For engineers reviewing the PTVS3V3Z1BSC datasheet, PTVS3V3Z1BSC pinout, PTVS3V3Z1BSC application, or PTVS3V3Z1BSC equivalent, key selection criteria include bidirectional clamping performance, ultra-low capacitance (180 pF), sub-1 mm footprint, and verified 82 A measured peak pulse robustness per IEC 61000-4-5.
Technical Context
This device implements a symmetrical bidirectional TVS structure with dual cathodes (K1/K2), enabling clamping of both positive and negative transients on a single line referenced to ground. Its low dynamic resistance (0.05 Ω) and fast response (<1 ns rise time per IEC 61000-4-2) ensure effective suppression of ESD and electrical fast transients without signal distortion.
The DSN1006-2 package integrates two discrete TVS junctions in one ultra-compact leadless body (1.0 × 0.6 × 0.27 mm), optimized for high-density PCB layouts where trace inductance must be minimized - critical for maintaining clamping integrity during sub-100 ns ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Ensures no conduction during normal 3.3 V rail operation; defines maximum continuous working voltage. |
| Clamping Voltage (70 A) | 11 V (typ.) - Limits transient voltage seen by downstream ICs to safe levels during IEC 61000-4-5 8/20 µs surges. |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact) - Protects against human-body-model discharges without degradation. |
| Diode Capacitance | 180 pF (typ., 0 V bias) - Low enough for audio and high-speed data lines without signal attenuation or timing skew. |
| Peak Pulse Current | 70 A (8/20 µs) - Sustains industrial-grade surge energy without failure; measured up to 82 A. |
| Dynamic Resistance | 0.05 Ω - Minimizes voltage overshoot during fast-rising transients by reducing IR drop across the device. |
| Breakdown Voltage | 4.9 V (typ., 10 mA) - Defines onset of avalanche conduction; ensures clean turn-on above standby voltage. |
Pinout & Package
DSN1006-2 (SOD993B) is a 2-terminal, leadless, ultra-compact surface-mount package measuring 1.0 × 0.6 × 0.27 mm. The marking bar identifies the cathode side; terminals are co-planar with no leads, requiring precise reflow soldering per IPC-7095 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of first TVS junction | Provides low-impedance path to ground for positive transients on the protected line. |
| 2 (K2) | Cathode of second TVS junction | Provides low-impedance path to ground for negative transients - enables true bidirectional clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection | Single-device solution for ±30 kV contact discharge on one line - eliminates need for dual-diode arrays or external polarity management. |
| Ultra-low clamping voltage | 11 V typical at 70 A ensures protected ICs (e.g., codec inputs, PMIC rails) remain within absolute maximum ratings during surge events. |
| Sub-1 mm footprint | 1.0 × 0.6 mm body enables placement directly at board edge connectors - critical for minimizing PCB trace inductance in ESD paths. |
| Low dynamic resistance | 0.05 Ω reduces voltage overshoot during nanosecond-scale ESD pulses, improving clamping fidelity over standard TVS diodes. |
| Low leakage current | 1 nA max at 3.3 V minimizes quiescent power loss in battery-powered devices and avoids signal rail loading. |
Applications
| Smartphone Audio Jack Protection | USB-C Power Delivery Line Clamp |
|---|---|
|
Use Scenario: Protecting analog audio signals (MIC, HP) from ESD events during headphone insertion/removal in smartphones. IC Role / Device Role / Timing Role: Bidirectional TVS placed between jack contacts and codec input pins to clamp ±8 kV ESD pulses before they reach sensitive analog circuitry. Use Value: 180 pF capacitance prevents high-frequency signal loss; 11 V clamping prevents codec latch-up or permanent damage. |
Use Scenario: Safeguarding 5–20 V power delivery lines in USB-C receptacles against hot-plug surges and system-level EFT. IC Role / Device Role / Timing Role: Standoff-rated TVS on VBUS line that activates only during transients >3.3 V, remaining transparent during normal PD negotiation and power transfer. Use Value: 70 A surge rating handles worst-case inrush and cable-induced spikes; 3.3 V VRWM avoids interference with PD communication signaling. |
| Wireless Earbud Battery Terminal Guard | Tablet Touchscreen I²C Line Suppressor |
|
Use Scenario: Shielding lithium-ion battery charge/discharge terminals from ESD during manufacturing handling and end-user service. IC Role / Device Role / Timing Role: Low-leakage TVS mounted directly at battery connector to shunt fast transients before reaching fuel gauge or charging IC. Use Value: 1 nA leakage preserves battery shelf life; bidirectional clamping accommodates reversible polarity during hot-swap events. |
Use Scenario: Preventing ESD-induced I²C bus lockup or display controller reset in tablet hinge-flex zones exposed to user touch. IC Role / Device Role / Timing Role: Capacitance-optimized TVS on SDA/SCL lines near display connector to clamp transients without distorting 400 kHz clock/data edges. Use Value: 180 pF ensures <1% signal rise-time degradation at 400 kHz; 11 V clamping protects controller GPIOs rated to 3.6 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.3A | Unidirectional; 3.3 V VRWM; DO-214AC package (4.5 × 2.7 mm); 60 A IPPM | Requires external series resistor or dual-device configuration for bidirectional protection; unsuitable for space-constrained audio ports. | Select only if board area allows larger package and unidirectional clamping suffices with added design complexity. |
| TPD2E001DRYR | 2-channel unidirectional TVS array; 0.65 pF per channel; 5 V VRWM; X2SON-6 package | Designed for high-speed data lines (USB 2.0, HDMI); lacks surge robustness (4 A IPPM) and cannot handle 70 A surges. | Prefer for low-capacitance data lines; avoid for battery/audio power-line surge protection due to insufficient IPPM rating. |
Compared with SMAJ3.3A and TPD2E001DRYR, PTVS3V3Z1BSC uniquely combines bidirectional operation, 70 A surge capability, and sub-1 mm size - making it the only option validated for compact, high-energy, single-line protection in portable power and audio systems.

FAQ
Is PTVS3V3Z1BSC suitable for protecting 5 V logic lines?
No - its 3.3 V reverse standoff voltage (VRWM) and 4.9 V typical breakdown voltage make it unsuitable for 5 V systems. Clamping begins near 5 V, risking false triggering during normal 5 V rail operation. Use PTVS5V0Z1BSC (5 V VRWM) instead for 5 V lines.
What is the significance of the dual cathode (K1/K2) pinning?
The dual cathode configuration enables symmetrical bidirectional clamping: K1 conducts positive transients to ground, K2 conducts negative transients to ground. This eliminates polarity dependency and allows single-line protection without external biasing or series components.
How does PTVS3V3Z1BSC compare to polymer-based TVS devices?
Unlike polymer TVS, PTVS3V3Z1BSC uses silicon avalanche diodes - delivering nanosecond response, precise clamping voltage, and repeatable performance over 100,000+ ESD events. Polymer devices exhibit higher clamping voltage drift and slower recovery, making them unsuitable for precision analog or high-speed digital protection.
Can this device replace a 0402-sized multilayer varistor (MLV)?
No - MLVs have higher capacitance (>500 pF), slower response (>100 ns), and degrade after repeated surges. PTVS3V3Z1BSC offers lower capacitance (180 pF), faster response (<1 ns), and stable clamping over lifetime - making it superior for audio and high-speed signal integrity, though not a direct footprint replacement.
