Diodes Incorporated B2100BE-13

Overview

B2100BE-13 from Diodes Incorporated is a 100 V, 2.0 A surface-mount Schottky barrier rectifier in SMB package, optimized for low forward voltage drop (0.79 V @ 2.0 A, 25°C), low leakage current (7 µA @ 100 V, 25°C), and high-frequency operation in DC-DC converters and polarity protection circuits.

For engineers reviewing the B2100BE-13 datasheet, B2100BE-13 pinout, B2100BE-13 application, or B2100BE-13 equivalent, key selection criteria include reverse voltage rating, thermal resistance (R_θJA = 100°C/W), junction capacitance (70 pF @ 4 V), guard ring die construction for transient immunity, and RoHS-compliant matte tin plating.

Technical Context

This Schottky rectifier uses a planar guard ring die structure to enhance surge robustness and suppress avalanche breakdown under repetitive transients. Its low VF and fast switching enable high-efficiency operation in 100 kHz–1 MHz DC-DC topologies without snubbers.

Designed for SMB package mounting, it delivers 2.0 A average forward current with derating above 25°C (see Figure 4), and exhibits stable IR up to 125°C (0.4 mA @ 100 V). Junction-to-case thermal resistance is 50°C/W, supporting conduction-cooled PCB layouts.

FAQ

What is the maximum junction temperature for B2100BE-13?

The absolute maximum junction temperature is +150°C, as specified in the Electrical Characteristics table. Operation above this limit risks permanent degradation of the Schottky junction. Derating begins at +25°C ambient, with I_O reduced linearly to zero at +150°C case temperature per Figure 4.

Is B2100BE-13 suitable for use in automotive under-hood applications?

B2100BE-13 is qualified to operate from –65°C to +150°C, meeting extended temperature requirements for many under-hood locations. However, it is not AEC-Q101 qualified; for automotive safety-critical systems, Diodes' AEC-Q101-certified SBM2100 or SBM2100A series should be used instead.

How does the guard ring construction improve reliability?

The guard ring die structure redistributes electric field stress away from the active junction periphery, suppressing premature edge breakdown during voltage transients. This increases I_FSM capability to 50 A and extends lifetime under repetitive surge conditions common in motor drive and inductive load switching.

Can B2100BE-13 replace B2100AE-13 in an existing design?

Yes, B2100BE-13 (SMB) can replace B2100AE-13 (SMA) if PCB layout accommodates the larger SMB footprint (4.06–4.57 mm wide vs. SMA's 4.00–4.60 mm length). Thermal resistance improves (100°C/W vs. 110°C/W), and mechanical robustness increases-but pad layout and stencil design must be updated.
