Product details
Overview
DF2B18FU,H3XHF from Toshiba Electronic Devices & Storage Corporation is an AEC-Q101-qualified bidirectional ESD protection diode in USC package, rated for ±30 kV IEC61000-4-2 contact discharge, 12 V working peak reverse voltage, and 2.5 A peak pulse current. It clamps transients to ≤33 V at 2.5 A and delivers 80 W peak pulse power for high-reliability automotive interface protection.
For engineers reviewing the DF2B18FU,H3XHF datasheet, DF2B18FU,H3XHF pinout, DF2B18FU,H3XHF application, or DF2B18FU,H3XHF equivalent, key selection criteria include IEC/ISO ESD rating compliance, low dynamic resistance (≤10 Ω), sub-10 pF capacitance, AEC-Q101 qualification status, and USC footprint compatibility with high-density PCB layouts.
Technical Context
This device implements a silicon epitaxial planar dual-diode structure configured in a common-cathode arrangement for bidirectional transient suppression. Its low 0.8 V dynamic resistance ensures minimal voltage overshoot during fast ESD events, while the 9 pF typical total capacitance preserves signal integrity on high-speed lines such as USB 2.0 or HDMI interfaces.
The DF2B18FU,H3XHF operates within a junction temperature range of −55 °C to +150 °C and is characterized per IEC61000-4-2 (contact/air), ISO10605 (contact/air), and IEC61000-4-5 (8/20 µs) standards. Its clamp voltage is guaranteed ≤33 V at 2.5 A IPP, supporting robust protection without compromising downstream IC tolerance margins.
