Nexperia USA Inc. PESD36VS1UL,315

Overview

PESD36VS1UL from Nexperia is a unidirectional ESD protection diode in DFN1006-2 (SOD882) package, designed to protect single signal lines against IEC 61000-4-2 contact discharge up to 30 kV and IEC 61000-4-5 surges (IPPM = 2.5 A, PPPM = 150 W), with reverse standoff voltage of 36 V, clamping voltage ≤80 V at 2.5 A, and capacitance of 18–30 pF - deployed in high-speed USB, HDMI, and audio interface lines.

For engineers reviewing the PESD36VS1UL datasheet, PESD36VS1UL pinout, PESD36VS1UL application, or PESD36VS1UL equivalent, this page delivers verified electrical parameters, validated AEC-Q101 qualification status, exact SOD882 footprint dimensions, real-world clamping behavior under 8/20 µs transients, and direct comparison to industry-standard alternatives for board-level ESD hardening.

Technical Context

This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VRWM = 36 V, then avalanches at VBR ≈ 39 V (IR = 2 mA) and clamps to ≤80 V during 2.5 A 8/20 µs surge events. Its ultra-low IRM < 1 nA at 36 V ensures minimal signal loading on high-impedance data paths.

The device uses silicon PN-junction technology with dynamic resistance Rdyn ≈ 9.5 Ω (TLP, 10 A), enabling fast response (<1 ns rise time per IEC 61000-4-2) and stable clamping across temperature. Its DFN1006-2 package supports automated placement and reflow while maintaining thermal dissipation capability up to Tj = 150 °C.

FAQ

What is the maximum junction temperature for continuous operation?

The absolute maximum junction temperature is 150 °C per IEC 60134 limiting values. Derating begins above 25 °C ambient, with rated peak pulse power decreasing linearly to zero at 150 °C junction temperature. Thermal resistance Rth(j-a) is not specified, so PCB copper area and via count must be validated per application.

Can PESD36VS1UL protect bidirectional signals like RS-232 or CAN?

No - PESD36VS1UL is unidirectional and only protects signals referenced to ground with defined polarity. For bidirectional lines such as RS-232 or CAN, a symmetric dual-diode array (e.g., PESD5V0S1BA) or dedicated bidirectional TVS is required to clamp both positive and negative transients.

How does its clamping voltage compare to competing 36 V diodes?

At IPPM = 2.5 A, PESD36VS1UL clamps to ≤80 V, matching industry benchmarks like Vishay's SMAJ36A. Its dynamic resistance of 9.5 Ω (TLP, 10 A) ensures tighter clamping consistency than higher-Rdyn alternatives, reducing voltage overshoot during fast-rising ESD events.

Is the DFN1006-2 package compatible with standard reflow profiles?

Yes - the device is qualified for JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C. The recommended solder paste stencil aperture is 0.3 mm × 0.9 mm per pad (Fig. 10), and thermal relief vias under the thermal pad are not required due to the absence of an exposed thermal pad in SOD882.
