Product details
Overview
PTVS4V5D1BL-QYL from Nexperia is a bidirectional transient voltage suppressor (TVS) in DFN1006-2 (SOD882) 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 10.3 V (typ.) under 34 A 8/20 µs surge, and maintains 4.5 V reverse standoff voltage - deployed in automotive battery lines and portable audio interfaces.
For engineers reviewing the PTVS4V5D1BL-QYL datasheet, PTVS4V5D1BL-QYL pinout, PTVS4V5D1BL-QYL application, or PTVS4V5D1BL-QYL equivalent, key selection criteria include bidirectional clamping performance, ultra-low dynamic resistance (0.1 Ω), AEC-Q101 qualification, 65 pF capacitance at 0 V, and DFN1006-2 footprint compatibility with high-density PCB layouts.
Technical Context
This device implements a symmetrical dual-cathode TVS structure enabling bidirectional clamping without polarity constraints. Its VBR = 4.7 V (min) and VRWM = 4.5 V support low-voltage rail protection while maintaining <0.1 µA leakage at rated standoff.
Clamping is characterized by TLP-measured Rdyn = 0.1 Ω and VCL = 10.3 V (typ.) at 34 A, 8/20 µs - confirming robust energy handling with minimal voltage overshoot during transients. The 65–78 pF capacitance at 1 MHz ensures minimal signal distortion on audio and data lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 4.5 V - Maximum continuous reverse voltage before leakage exceeds specification; defines safe operating window for 3.3 V/5 V systems. |
| VBR (min) | 4.7 V - Breakdown initiates reliably above VRWM, ensuring tight margin between standby and clamping onset. |
| VCL (typ., 34 A) | 10.3 V - Peak clamped voltage during full-rated 8/20 µs surge; limits stress on downstream ICs like audio codecs or CAN transceivers. |
| IPPM | 34 A - Peak pulse current rating per IEC 61000-4-5; validates protection against lightning-induced surges in automotive supply lines. |
| Rdyn | 0.1 Ω - Dynamic resistance measured via TLP; enables fast, low-overshoot clamping critical for high-speed interface protection. |
| Cd (at 0 V) | 65 pF - Diode capacitance at zero bias; low enough to avoid signal integrity degradation on USB 2.0 or I²S audio paths. |
| ESD Rating | ±30 kV - Contact discharge per IEC 61000-4-2; qualifies for direct connector-level ESD hardening in handheld consumer devices. |
Pinout & Package
PTVS4V5D1BL-QYL uses the DFN1006-2 (SOD882) ultra-compact leadless package: 1.0 mm × 0.6 mm × 0.48 mm body, 0.65 mm pitch, with exposed copper terminals on bottom side for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Terminal for first diode anode connection in bidirectional configuration; forms one half of symmetrical clamping path. |
| 2 | Cathode (Diode 2) | Terminal for second diode anode connection; paired with Pin 1 to enable symmetric ±V clamping across protected line and ground. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection | Supports ±30 kV contact discharge on same line without polarity sensitivity - eliminates need for external series resistors or directional layout constraints. |
| Ultra-low dynamic resistance | 0.1 Ω (TLP) ensures minimal voltage rise during fast transients, preserving timing margins in high-speed analog and digital interfaces. |
| AEC-Q101 qualified | Validated for automotive underhood and infotainment applications, including temperature cycling (-55 °C to +150 °C) and humidity testing. |
| Low clamping voltage | 10.3 V typical at 34 A enables protection of 12 V automotive electronics without overvoltage damage to downstream regulators or microcontrollers. |
| Minimal parasitic capacitance | 65 pF at 0 V allows integration on audio differential pairs (e.g., headset mic/line-out) without audible artifacts or bandwidth loss. |
Applications
| Automotive Battery Line Protection | Portable Audio Interface ESD Hardening |
|---|---|
|
Use Scenario: Protecting 12 V battery feed lines in automotive infotainment head units against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS placed at connector entry point to clamp positive and negative transients before reaching DC-DC converters and MCU power rails. Use Value: Withstands 34 A 8/20 µs surges and maintains ≤13.2 V clamping, preventing brownout or latch-up in PMICs and SoCs. |
Use Scenario: Shielding stereo headphone jack and microphone input on smartphones and tablets from user-handling ESD events. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted directly adjacent to jack pins to shunt ±8 kV air discharge pulses before reaching codec inputs.

| USB 2.0 Data Line Surge Suppression | Industrial Sensor Signal Conditioning Input |
|
Use Scenario: Adding secondary surge protection on USB D+/D− lines in industrial docking stations exposed to field wiring transients. IC Role / Device Role / Timing Role: Secondary TVS after primary common-mode choke, absorbing differential-mode surges that bypass filtering. Use Value: 0.1 Ω Rdyn minimizes signal reflection; 10.3 V clamping prevents damage to USB PHY transceivers rated for 3.6 V max VI/O. |
Use Scenario: Protecting analog front-end inputs of 4–20 mA loop-powered sensors in factory automation against cable-induced surges. IC Role / Device Role / Timing Role: Bidirectional clamping element across sensor input terminals to ground, handling both polarity transients on two-wire loops. Use Value: 4.5 V VRWM aligns with typical loop supply headroom; 34 A IPPM supports IEC 61000-4-5 Level 4 compliance for harsh industrial environments. |
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 SZ1.5SMC4.5A | Unidirectional, DO-214AB package (3.5 mm × 2.7 mm), higher VCL = 14.4 V at 30 A, 1.5 kW peak power. | Requires separate diodes for bidirectional protection; unsuitable for space-constrained audio or USB layouts. | Select only when board area permits larger package and unidirectional topology is acceptable with external routing. |
| Vishay SMAJ4.5A | Unidirectional, SMA package (4.5 mm × 2.7 mm), VCL = 11.2 V at 32.1 A, 400 W peak power, no AEC-Q101 qualification. | Lacks automotive qualification and bidirectional capability; requires dual-device implementation for ± protection. | Prefer for cost-sensitive non-automotive consumer applications where footprint and qualification are secondary. |
Compared with SZ1.5SMC4.5A and SMAJ4.5A, PTVS4V5D1BL-QYL offers true bidirectional operation in a 60% smaller footprint, AEC-Q101 validation, and lower clamping voltage - making it uniquely suited for automotive and portable electronics where size, reliability, and polarity-agnostic protection are mandatory.

FAQ
Is PTVS4V5D1BL-QYL bidirectional or unidirectional?
PTVS4V5D1BL-QYL is a bidirectional TVS diode, confirmed by its dual-cathode pinning (Pins 1 and 2 both labeled "K") and symmetrical V-I characteristics in Figures 3, 5, and 6. It clamps equally for positive and negative transients without polarity dependency, enabling single-device protection of AC-coupled or floating lines.
What is the maximum junction temperature and storage temperature range?
The absolute maximum junction temperature (Tj) is 150 °C, and the storage temperature (Tstg) range is –65 °C to +150 °C, per Table 5 (Limiting Values). These ratings are validated under AEC-Q101 stress test conditions and support operation in under-hood automotive environments.
Does PTVS4V5D1BL-QYL require a heatsink in standard PCB mounting?
No heatsink is required. The DFN1006-2 package relies on PCB copper pour for thermal dissipation. With its 34 A 8/20 µs rating and low RthJA (typ. ~200 K/W on 1 cm² 1 oz Cu), standard FR-4 layouts with adequate ground plane coupling fully satisfy thermal requirements per Nexperia's solder land recommendations in Figure 12.
How does its 65 pF capacitance impact high-speed signal integrity?
At 65 pF (measured at 1 MHz, 0 V), PTVS4V5D1BL-QYL introduces negligible loading on audio (≤20 kHz), I²C, and low-speed USB 2.0 signals. For USB 2.0 (480 Mbps), insertion loss remains below 0.5 dB up to 100 MHz per Nexperia's characterization - verified in Fig. 4 and application note AN11524.
