Infineon Technologies BAT60AE6327HTSA1

Overview

BAT60AE6327HTSA1 from Infineon Technologies is a silicon Schottky diode optimized for low-voltage power rectification and clamping, featuring a typical forward voltage of 0.12 V at 10 mA, 10 V reverse voltage rating, and 3 A continuous forward current capability. It is qualified to AEC-Q101 and used in automotive power supply rails, USB port protection, and DC-DC step-up converter catch diodes.

For engineers reviewing the BAT60AE6327HTSA1 datasheet, BAT60AE6327HTSA1 pinout, BAT60AE6327HTSA1 application, or BAT60AE6327HTSA1 equivalent, key selection criteria include ultra-low VF for efficiency-critical 1.8–3.3 V systems, SOD323 package thermal performance (RthJS ≤ 90 K/W), and verified ESD robustness per AEC-Q101.

Technical Context

This Schottky diode employs a planar silicon process with metal-semiconductor junction design to achieve sub-0.2 V forward conduction at 100 mA. Its low CT of 20–35 pF at 5 V reverse bias supports high-frequency switching in boost converters and RF detection circuits.

The device operates across –55 °C to +85 °C ambient, with junction temperature limited to 150 °C and derated reverse voltage above 25 °C per published VR vs. TA curve. Thermal resistance from junction to soldering point is ≤90 K/W, enabling reliable operation on standard FR4 PCBs without heatsinking.

FAQ

What is the maximum allowable junction temperature for BAT60AE6327HTSA1?

The absolute maximum junction temperature is 150 °C. Operation beyond this limit risks irreversible degradation of the Schottky barrier. Derating curves in the datasheet define permissible VR and IF at elevated ambient temperatures, and thermal design must ensure RthJA remains within limits to maintain Tj ≤ 150 °C under worst-case load and ambient conditions.

Is BAT60AE6327HTSA1 suitable for reverse polarity protection in 3.3 V systems?

Yes - its 0.12 V typical forward voltage at 10 mA yields <0.4 mW conduction loss at 10 mA, and its 3 A rating supports inrush currents during hot-plug events. The SOD323 package's low thermal resistance ensures stable operation even during brief 2 A surges, provided PCB copper area meets recommended layout guidelines.

Does BAT60AE6327HTSA1 require special ESD handling during assembly?

Yes - it is classified as ESD-sensitive per AEC-Q101. Handling requires grounded workstations, ionized air, and ESD-safe packaging. The device withstands ≥2 kV HBM per qualification, but uncontrolled discharge during manual placement or reflow can degrade VF consistency or cause latent failure in high-reliability applications.

Can BAT60AE6327HTSA1 be used as a replacement for BAT54 in existing designs?

No - although both are SOD323 Schottkys, BAT60A has significantly lower VF (0.12 V vs. 0.33 V typ. @ 10 mA) and higher IF (3 A vs. 200 mA), resulting in different thermal and current-handling behavior. Direct substitution may cause unexpected thermal saturation or altered regulation dynamics in legacy BAT54-based circuits without layout and thermal review.
