Nexperia USA Inc. PTVS5V0Z1UPCAZ

Overview

PTVS5V0Z1UPCAZ from Nexperia is a unidirectional transient voltage suppressor diode in DFN1610-2 (SOD1610-1) package, designed to protect single-line interfaces against IEC 61000-4-5 surges and IEC 61000-4-2 ESD events. It features a 5 V reverse standoff voltage (VRWM), 150 A rated peak pulse current (IPPM), and ultra-low 8.5 V typical clamping voltage at 150 A - enabling robust protection for low-voltage USB, I²C, and GPIO lines in portable electronics.

For engineers reviewing the PTVS5V0Z1UPCAZ datasheet, PTVS5V0Z1UPCAZ pinout, PTVS5V0Z1UPCAZ application, or PTVS5V0Z1UPCAZ equivalent, key selection criteria include clamping performance under 8/20 µs surge, ESD immunity (30 kV contact/air), diode capacitance (600 pF), unidirectional polarity handling, and ultra-small 1.6 × 1 × 0.55 mm footprint compatibility with high-density PCB layouts.

Technical Context

This TVS diode operates as a unidirectional clamping device, conducting only during positive overvoltage transients on the anode-to-cathode path. Its breakdown voltage (VBR) ranges from 5.1 V to 7 V at 1 mA, ensuring reliable turn-on above VRWM = 5 V while maintaining sub-1 µA leakage at rated standoff.

The device delivers consistent clamping across surge conditions: 8.5 V typical (max 10 V) at 150 A (8/20 µs), validated per IEC 61000-4-5, and exhibits symmetric TLP response down to −30 A with <10 V negative clamping - critical for bidirectional signal line protection where polarity is fixed relative to ground.

FAQ

Is PTVS5V0Z1UPCAZ suitable for bidirectional signal lines like RS-485?

No - PTVS5V0Z1UPCAZ is unidirectional and only clamps positive transients on the cathode line. For bidirectional lines such as RS-485 or CAN, a bidirectional TVS (e.g., PTVS5V0Z2UPCAZ) or back-to-back diode configuration is required to suppress both polarities. Using this part on a truly bidirectional net would leave negative transients unprotected.

What is the thermal resistance (RθJA) of the DFN1610-2 package?

The datasheet does not specify RθJA for PTVS5V0Z1UPCAZ. Thermal performance depends entirely on PCB layout: copper area, thickness, and via count under the terminals. Nexperia recommends ≥20 mm² of 1 oz copper connected to both pins, with ≥4 thermal vias (0.3 mm diameter) per terminal to achieve effective heat dissipation during repetitive surge events.

Can PTVS5V0Z1UPCAZ be used on a 3.3 V supply rail without risk of leakage-induced dropout?

Yes - at VRWM = 5 V, the device exhibits ≤1 µA reverse leakage at 25 °C and remains <5 µA up to 85 °C. When placed across a 3.3 V rail (well below VRWM), leakage is negligible (<10 nA), posing no measurable impact on regulator load or battery runtime in always-on applications.

Does the 150 A IPPM rating apply to repetitive surges or only single-event testing?

The 150 A IPPM rating is defined per IEC 61000-4-5 for non-repetitive 8/20 µs pulses. The device is not rated for repetitive surges at this amplitude. For applications involving frequent transients (e.g., motor commutation noise), derating to ≤30 A peak and verifying junction temperature rise using thermal modeling is required to ensure long-term reliability.
