Product details
Overview
PESD24VF1BSF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) package, designed to protect one high-speed signal line against ±10 kV IEC 61000-4-2 ESD events while maintaining ultra-low 0.25 pF capacitance, 24 V reverse standoff voltage, and 17 V clamping voltage at 1 A peak pulse current - deployed in NFC antenna interfaces and USB/MIPI data lines.
For engineers reviewing the PESD24VF1BSF datasheet, PESD24VF1BSF pinout, PESD24VF1BSF application, or PESD24VF1BSF equivalent, key selection criteria include sub-0.4 pF capacitance for RF integrity, bidirectional clamping symmetry, 24 V working voltage margin, and ultra-small 0.6 × 0.3 mm footprint for space-constrained antenna feedlines and high-density mobile PCBs.
Technical Context
This device implements a dual-cathode, bidirectional TVS structure with matched breakdown voltages (24.5–28 V) and symmetric clamping behavior (±17 V at 1 A), enabling protection of AC-coupled or bipolar signal paths without polarity constraints. Its low dynamic resistance (0.7 Ω) ensures rapid transient energy diversion during ESD strikes.
The DSN0603-2 package places both cathodes on opposing terminals with no anode connection - forming a back-to-back diode pair that conducts only during overvoltage transients while presenting <1 nA leakage at 24 V DC bias, preserving signal fidelity in 13.56 MHz NFC and >100 Mbps data links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Diode capacitance | 0.25 pF typical at 1 MHz, 0 V bias - preserves signal integrity on 13.56 MHz NFC antennas and high-speed digital lines. |
| Reverse standoff voltage | 24 V - supports continuous operation on 18–24 V signal rails without leakage-induced power loss. |
| Clamping voltage | 17 V maximum at 1 A 8/20 µs pulse - limits transient voltage to safe levels for downstream 24 V-tolerant receivers. |
| ESD rating | ±10 kV contact discharge per IEC 61000-4-2 - meets industrial and portable electronics immunity requirements. |
| Peak pulse current | 1 A per 8/20 µs waveform - handles multiple ESD events without degradation under standard test conditions. |
| Dynamic resistance | 0.7 Ω typical - minimizes voltage overshoot during fast-rising ESD transients (<1 ns rise time). |
Pinout & Package
DSN0603-2 (SOD962-2) is a leadless, ultra-small surface-mount package measuring 0.6 × 0.3 × 0.3 mm with two terminals and a cathode-marking bar. The device uses a dual-cathode configuration with no dedicated anode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Forms first half of back-to-back diode pair; connects to protected line when transient exceeds +24.5 V. |
| 2 | Cathode (Diode 2) | Forms second half of back-to-back diode pair; conducts when transient falls below −24.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping symmetry | Matched ±24.5 V breakdown and ±17 V clamping enables protection of AC-coupled or floating signal lines without polarity biasing. |
| Ultra-low capacitance | 0.25 pF typical - avoids resonance and insertion loss in 13.56 MHz NFC antenna matching networks and high-speed serial links. |
| Low dynamic impedance | 0.7 Ω - reduces clamping voltage overshoot during sub-nanosecond ESD edge rates, improving protection margin. |
| Small-footprint packaging | 0.6 × 0.3 mm DSN0603-2 - fits directly adjacent to RF connectors and IC pads in slim mobile form factors. |
Applications
| NFC Antenna Protection | USB 2.0 Data Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G | 3.3 V VRWM, 0.65 pF capacitance - lower voltage rating and higher capacitance than PESD24VF1BSF. | Suitable for 3.3 V logic lines but unsuitable for 24 V signal rails or NFC antenna matching. | Select only for low-voltage digital I/O where clamping voltage must be <5 V. |
| TPD2E001DRYR | 5.5 V VRWM, 1.9 pF capacitance, integrated 100 Ω series resistor - higher capacitance and added series impedance. | Designed for USB/DisplayPort with built-in current limiting; not optimized for RF or high-speed differential signals. | Prefer for cost-sensitive USB ports where 1.9 pF is acceptable; avoid in RF or >100 Mbps applications. |
Compared with ESD5Z3.3T5G and TPD2E001DRYR, PESD24VF1BSF uniquely delivers 24 V standoff with sub-0.4 pF capacitance - making it the only option among the three for protecting NFC antennas, 24 V industrial data lines, and high-speed differential interfaces without signal degradation.

FAQ
What is the maximum operating temperature for PESD24VF1BSF?
The PESD24VF1BSF has a specified junction temperature range of −45 °C to +125 °C and ambient operating temperature range of −45 °C to +125 °C, validated per IEC 60134 limiting values. It is rated for continuous use in automotive under-hood environments and industrial control cabinets without derating up to 125 °C ambient.
Can PESD24VF1BSF protect bidirectional analog signals like audio or sensor outputs?
Yes - its symmetrical bidirectional clamping (±24.5 V breakdown, ±17 V clamping) and ultra-low 0.25 pF capacitance make it suitable for protecting AC-coupled analog signals such as microphone inputs, piezoelectric sensor outputs, and differential audio lines where signal fidelity and DC bias stability are essential.
Does PESD24VF1BSF require external biasing or series resistors?
No - PESD24VF1BSF operates passively with no external components required. Its dual-cathode configuration provides inherent bidirectional conduction above ±24.5 V, and its <1 nA reverse leakage at 24 V ensures negligible impact on DC bias points or high-impedance sensor nodes.
How does the DSN0603-2 package affect PCB layout for optimal ESD performance?
Optimal ESD performance requires placing the DSN0603-2 device within 2 mm of the protected connector, routing the protected trace directly through the device with minimal stub length, using solid ground plane beneath the device, and avoiding parallel routing with noisy power traces - all enabled by its 0.6 × 0.3 mm footprint and low-inductance terminal geometry.
