Nexperia USA Inc. PESD5V0L1BSF,315

Overview

PESD5V0L1BSF,315 from Nexperia USA Inc. is a bidirectional low-capacitance ESD protection diode designed to protect one signal line from electrostatic discharge and other transient events. The device is supplied in a SOD962 / DSN0603-2 leadless ultra-small SMD package, supports a ±5 V reverse standoff voltage, provides 12 pF typical diode capacitance, and is rated for ESD protection up to ±30 kV according to IEC 61000-4-2.

For engineers reviewing the PESD5V0L1BSF,315 datasheet, PESD5V0L1BSF,315 pinout, PESD5V0L1BSF,315 application, or PESD5V0L1BSF,315 equivalent, this device is most relevant for compact 5 V signal-line protection in cellular accessories, portable electronics, communication systems, computers, and peripheral interfaces requiring low package height, bidirectional clamping, and connector-side ESD robustness.

Technical Context

PESD5V0L1BSF,315 protects a single signal or data line between pin 1 and pin 2 in a bidirectional configuration. Its key electrical limits include ±5 V reverse standoff voltage, 6 V to 10 V symmetrical breakdown voltage at 1 mA, 100 nA maximum reverse leakage at 5 V, and 11.5 V maximum clamping voltage at 1 A under an 8/20 μs surge pulse condition.

The device combines low board-area demand with defined transient capability: 35 W rated peak pulse power, 3 A rated peak pulse current for an 8/20 μs waveform, 0.05 nH typical series inductance, 1 Ω typical dynamic resistance under TLP conditions, and ±30 kV contact and air discharge ESD ratings. Diode capacitance is 12 pF typical at 0 V and 8 pF typical at 5 V, making the device more suitable for moderate-speed and general signal lines than for ultra-high-speed interfaces that require sub-pF capacitance.

Applications

Equivalent & Alternatives

When evaluating PESD5V0L1BSF,315 equivalent devices, engineers should compare working voltage, bidirectional versus unidirectional structure, diode capacitance, clamping voltage, peak pulse current, ESD rating, SOD962 footprint compatibility, and whether the protected interface can tolerate the replacement device's capacitance and clamping behavior.

Compared with PESD5V0L1USF,315, PESD5V0L1BSF,315 is optimized for bidirectional signal-line protection where the transient or signal polarity can appear in either direction. PESD5V0L1BSF,315 vs PESD5V0S1BSF,315 selection depends mainly on allowable line capacitance, while PESD5V0L1BSF,315 vs PESD5V0R1BSFYL selection depends on the tradeoff between ±30 kV ESD robustness and ultra-low capacitance for high-speed interfaces.

FAQ

What is PESD5V0L1BSF,315 used for?

PESD5V0L1BSF,315 is used to protect one low-voltage signal or data line from ESD and surge transients. It is suitable for portable electronics, cellular accessories, communication systems, computers, and peripheral interfaces that need a 5 V bidirectional ESD diode in an ultra-small SOD962 package.

Is PESD5V0L1BSF,315 bidirectional or unidirectional?

PESD5V0L1BSF,315 is bidirectional. Its symmetrical breakdown behavior allows protection from pin 1 to pin 2 and from pin 2 to pin 1, which is useful for signal lines that can experience positive and negative transients relative to the local return path.

What capacitance does PESD5V0L1BSF,315 add to a signal line?

PESD5V0L1BSF,315 has 12 pF typical diode capacitance at 0 V and 8 pF typical capacitance at 5 V, measured at 1 MHz. Engineers should compare this capacitance with the interface bandwidth and signal-integrity margin before using it on faster data lines.

What package is used by PESD5V0L1BSF,315?

PESD5V0L1BSF,315 uses the SOD962 / DSN0603-2 leadless ultra-small package with two terminals, 0.4 mm pitch, and 0.6 mm × 0.3 mm × 0.3 mm body dimensions. This package is intended for compact, low-profile surface-mount ESD placement near the protected line.

What should be considered in PESD5V0L1BSF,315 PCB layout?

PESD5V0L1BSF,315 should be placed close to the input terminal, connector, exposed pad, or transient entry point. The protected-line path to the ESD diode should be short, the transient return path should be minimized, and ground vias or ground-plane access should be used where possible to reduce clamping overshoot during fast ESD events.

What are common PESD5V0L1BSF,315 equivalent options?

Common comparison options include PESD5V0L1USF,315 for a unidirectional 5 V version, PESD5V0S1BSF,315 for a similar bidirectional SOD962 option with higher capacitance, and PESD5V0R1BSFYL for ultra-low 0.1 pF capacitance in high-speed interface protection. Selection depends on polarity, capacitance, ESD rating, clamping behavior, and footprint compatibility.
