Product details
Overview
PTVS4V8Z1UPCAZ from Nexperia is a unidirectional transient voltage suppressor (TVS) diode in a DFN1610-2 (SOD1610-1) package, designed for single-line ESD and surge protection in space-constrained portable electronics. It features a 4.8 V reverse standoff voltage (VRWM), 150 A rated peak pulse current (IPPM), 8.5 V typical clamping voltage (VCL) at 150 A, and 600 pF diode capacitance at 1 MHz - enabling robust protection without signal integrity degradation on high-speed lines.
For engineers reviewing the PTVS4V8Z1UPCAZ datasheet, PTVS4V8Z1UPCAZ pinout, PTVS4V8Z1UPCAZ application, or PTVS4V8Z1UPCAZ equivalent, this page delivers verified electrical parameters, validated DFN1610-2 terminal mapping, real-world use cases in power management and USB interface protection, and confirmed alternative parts with documented clamping and leakage differences.
Technical Context
This unidirectional TVS operates as a clamping device triggered above its 5.1–7 V breakdown voltage (VBR), holding transients to ≤10 V during 8/20 µs IEC 61000-4-5 surges up to 150 A. Its ultra-low 8.5 V clamping at rated current ensures downstream ICs remain within safe operating limits under fast-rising transients.
With 1 µA max reverse leakage at 4.8 V and 600 pF capacitance at 0 V bias, it supports low-power, high-frequency applications including USB 2.0 data lines and battery-charger inputs where minimal loading and ESD immunity (±30 kV contact/air per IEC 61000-4-2) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 4.8 V - Maximum continuous reverse voltage before leakage exceeds 1 µA; defines operating window for protected line. |
| VBR | 5.1–7 V at 1 mA - Breakdown onset range; ensures reliable turn-on before system damage thresholds. |
| VCL | 8.5 V typ. at 150 A - Clamped voltage during full-rated 8/20 µs surge; guarantees <8.5 V stress on downstream ICs. |
| IPPM | 150 A - Peak pulse current rating per IEC 61000-4-5; validates protection against lightning-induced surges. |
| Cd | 600 pF at 1 MHz, 0 V - Capacitance level compatible with USB 2.0 (≤1 nF limit) and low-speed serial interfaces. |
| ESD Rating | ±30 kV (IEC 61000-4-2, contact/air) - Full-system ESD immunity without external shielding or layout reinforcement. |
Pinout & Package
PTVS4V8Z1UPCAZ uses the DFN1610-2 (SOD1610-1) leadless surface-mount package: 1.6 × 1.0 × 0.55 mm body, 0.45 mm terminal pitch, and coplanar copper terminals suitable for reflow soldering with 0.1 mm stencil thickness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line; conducts surge current toward ground when forward-biased by positive transients. |
| 2 (A) | Anode | Connected to ground reference; completes clamping path during overvoltage events on the protected line. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping | Protects positive-polarity lines only (e.g., VBUS, USB D+, power rails); avoids false triggering on negative excursions. |
| Ultra-low clamping voltage | 8.5 V typical at 150 A ensures logic-level ICs (e.g., 5 V microcontrollers, USB PHYs) stay within absolute maximum ratings during surge events. |
| Low capacitance | 600 pF enables integration on 480 Mbps USB 2.0 data paths without signal rise-time degradation or eye-diagram closure. |
| High ESD robustness | ±30 kV IEC 61000-4-2 rating eliminates need for secondary ESD components in handheld device front-end designs. |
Applications
| USB 2.0 Data Line Protection | Portable Device Power Input |
|---|---|
|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in smartphones and tablets against ESD and cable discharge events. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between data line and ground, activated within nanoseconds of ESD strike. Use Value: 600 pF capacitance preserves signal integrity at 480 Mbps; ±30 kV ESD rating meets IEC 61000-4-2 Level 4 compliance without layout derating. |
Use Scenario: Safeguarding 5 V input rails of battery chargers and PMICs in wearables and Bluetooth earbuds from hot-plug surges and adapter transients. IC Role / Device Role / Timing Role: Standoff-clamp TVS connected between VBUS and GND, absorbing 150 A 8/20 µs pulses without thermal runaway. Use Value: 4.8 V VRWM aligns with 5 V nominal supply; 8.5 V clamping prevents overvoltage damage to LDOs and charging controllers. |
| Industrial Sensor Interface | Automotive Body Control Module (Non-AEC-Q) |
|
Use Scenario: Shielding analog sensor inputs (e.g., temperature, pressure) in factory automation equipment from induced surges on long PCB traces. IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) TVS placed at connector entry point, shunting transients before signal conditioning circuitry. Use Value: 1 µA IRM at 4.8 V avoids DC offset errors in µA-range sensor bias networks; 125 °C ambient rating supports industrial temperature operation. |
Use Scenario: Adding cost-effective surge suppression to non-safety-critical 12 V accessory lines (e.g., LED lighting control, HVAC fan drivers) in aftermarket automotive modules. IC Role / Device Role / Timing Role: Primary transient clamp on switched 12 V supply rail, mounted adjacent to connector to minimize inductance. Use Value: 150 A IPPM withstands load-dump spikes per ISO 7637-2 Pulse 5a; DFN1610-2 footprint reduces board area vs. SMA/SMB alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ4.5A | Higher VRWM (4.5 V), higher VCL (11.2 V at 13.9 A), SMA package (4.5 × 2.7 mm) | Lower surge rating (13.9 A vs. 150 A); suited for lower-energy transients | Select when board space allows larger package and clamping voltage margin >11 V is acceptable. |
| TPSMF4.5A | Same VRWM (4.5 V), lower VCL (9.6 V at 100 A), SOD-123FL package (2.7 × 1.7 mm) | Reduced surge capacity (100 A vs. 150 A); 1.2× larger footprint than DFN1610-2 | Choose for legacy SMT lines supporting SOD-123FL, or where 9.6 V clamping suffices for 5 V systems. |
Compared with SMAJ4.5A and TPSMF4.5A, PTVS4V8Z1UPCAZ delivers 11× higher surge current handling in 40% less board area and 1.5 V lower clamping - making it optimal for next-gen portable electronics requiring miniaturization and robust IEC 61000-4-5 compliance.

FAQ
What is the maximum junction temperature for PTVS4V8Z1UPCAZ?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in the Limiting Values table. This rating enables operation in high-density PCB environments such as smartphone mainboards and wearable charging circuits where localized heating occurs. Thermal derating is not required below this threshold under specified surge conditions.
Can PTVS4V8Z1UPCAZ be used on bidirectional signal lines like RS-485?
No - PTVS4V8Z1UPCAZ is unidirectional and only protects against positive transients relative to ground. For bidirectional lines, a symmetric (bidirectional) TVS such as PTVS3V3S1UR must be used. Using this part on RS-485 would leave negative transients unprotected and risk device failure.
Is the 600 pF capacitance measured at zero bias or operating voltage?
The 600 pF typical capacitance is measured at 1 MHz with 0 V DC bias and 25 °C ambient temperature, per Table 6 (Characteristics). Capacitance decreases under reverse bias - e.g., ~450 pF at 4.8 V - which further minimizes loading on active signal lines.
Does PTVS4V8Z1UPCAZ meet AEC-Q200 for automotive use?
No - this device is not AEC-Q200 qualified. The datasheet explicitly states "Non-automotive qualified products" in Section 14, and no automotive stress test data (e.g., temperature cycling, humidity bias) is included. It may be used in aftermarket or non-safety-critical automotive accessories only at the designer's own risk.
