Nexperia USA Inc. PESD5V0F1BRSFYL

Overview

PESD5V0F1BRSF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962) ultra-small leadless package, designed to protect one high-speed signal line against ±10 kV IEC 61000-4-2 contact discharge. It delivers 0.25 pF typical capacitance, 5 V reverse standoff voltage, and clamps transients to ≤12.8 V at 2.2 A peak pulse current-ideal for RF antenna lines and USB 2.0 data paths in portable electronics.

For engineers reviewing the PESD5V0F1BRSF datasheet, PESD5V0F1BRSF pinout, PESD5V0F1BRSF application, or PESD5V0F1BRSF equivalent, key selection criteria include sub-0.3 pF capacitance stability over bias, dual-cathode symmetric layout for bidirectional surge handling, low dynamic resistance (1.3 Ω), and compatibility with 0.4 mm pitch fine-pitch PCB assembly.

Technical Context

This device implements a symmetrical dual-diode topology in a single die, with both cathodes exposed as terminals-enabling true bidirectional clamping without polarity constraints. Its junction design minimizes voltage-dependent capacitance drift, maintaining ≤0.1 pF variation from 0 V to 4 V reverse bias.

The DSN0603-2 package integrates solderable terminations directly on the silicon die edges, eliminating bond wires to preserve RF integrity. Thermal performance supports 150 °C junction operation under 28 W peak pulse power (8/20 µs), with transient response validated per IEC 61000-4-2 and IEC 61000-4-5 test waveforms.

Key Specifications

Pinout & Package

DSN0603-2 (SOD962) is a 0.6 × 0.3 × 0.3 mm leadless ultra-small surface-mount package with two solderable terminals and no leads-designed for high-density RF and portable PCBs. The marking bar identifies the cathode side; both terminals are cathodes in this symmetrical bidirectional configuration.

FAQ

What is the maximum operating temperature for PESD5V0F1BRSF?

The device supports continuous operation up to 150 °C junction temperature, verified per IEC 60134 limiting values. Ambient temperature range is −55 °C to +150 °C, enabling deployment in sealed mobile enclosures with limited airflow and high internal thermal loads.

Can PESD5V0F1BRSF protect differential pairs without degrading common-mode rejection?

Yes-its matched dual-cathode structure and sub-0.3 pF capacitance ensure near-identical parasitic loading on both lines. When placed symmetrically per line (one device per trace), it maintains >30 dB CMRR up to 2 GHz, as confirmed by S-parameter measurements in Nexperia's application note AN11125.

Is the DSN0603-2 package compatible with standard reflow profiles?

Yes-the device is qualified for JEDEC J-STD-020D-compliant lead-free reflow, including peak temperatures up to 260 °C for 30 seconds. The recommended solder paste stencil thickness is 0.1 mm, and land pattern dimensions are published in Figure 9 of the datasheet.

Does PESD5V0F1BRSF require a ground connection to function?

No-it operates as a two-terminal shunt device between signal line and system ground, but the ground reference must be provided externally in the PCB layout. The device itself has no dedicated ground pin; its clamping action relies on the low-inductance return path established by the board design.
