Product details

Overview

BAT720/DG/B2,215 from NXP Semiconductors is a planar Schottky barrier diode with integrated guard ring for stress protection, housed in an SOT23 (TO-236AB) surface-mount package. It delivers 40 V reverse voltage rating, 550 mV forward voltage at 500 mA, and 60–90 pF capacitance at 1 MHz, enabling ultra-high-speed switching in automotive power rail clamping.

For engineers reviewing the BAT720/DG/B2,215 datasheet, BAT720/DG/B2,215 pinout, BAT720/DG/B2,215 application, or BAT720/DG/B2,215 equivalent, key selection criteria include AEC-Q101 qualification, low VF/low Cd trade-off, reverse polarity protection capability, and SOT23 footprint compatibility with high-density PCB layouts.

Technical Context

The BAT720/DG/B2,215 uses a planar Schottky junction structure with an integrated guard ring to enhance ESD and transient robustness without compromising switching speed. Its low forward voltage (550 mV @ 500 mA) and low capacitance (60–90 pF @ 0 V) are co-optimized for high-frequency line termination and clamping in 12 V automotive subsystems.

Thermal performance is defined for FR4 PCB mounting (single-sided copper, tin-plated), with R_th(j-a) = 500 K/W and T_j max = 125 °C. The device supports non-repetitive peak forward current up to 2 A (10 ms square wave), making it suitable for surge-limited protection paths.

Key Specifications

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NSS40201MR6T1G	40 V V_R, 480 mV V_F @ 500 mA, 110 pF C_d, SOT-23 package	Higher capacitance limits use above 2 Mbps; lower V_F improves efficiency in high-current paths	Select when forward loss dominates design priority and signal bandwidth ≤2 Mbps
