Product details

Overview

BAT240AE6327HTSA1 from Infineon Technologies is a Schottky barrier diode rated for 240 V reverse voltage, 400 mA average forward current, and 0.55 V typical forward voltage at 400 mA, used in low-loss DC-DC converter output rectification and auxiliary power supply freewheeling paths.

For engineers reviewing the BAT240AE6327HTSA1 datasheet, BAT240AE6327HTSA1 pinout, BAT240AE6327HTSA1 application, or BAT240AE6327HTSA1 equivalent, key selection criteria include reverse recovery time (unspecified but inherently zero), thermal resistance (R_thJA = 350 K/W), junction temperature limit (T_j = 150 °C), and SOT-23 package compatibility with high-density PCB layouts.

Technical Context

This diode employs a planar Schottky structure with a platinum-silicide (PtSi) anode on n-type silicon, enabling fast switching without minority-carrier storage delay. Its 240 V V_R rating supports operation across wide-input industrial SMPS rails, while the 400 mA I_F(AV) suits medium-current secondary-side rectification.

Thermal performance is defined by a 350 K/W junction-to-ambient resistance under standard JEDEC PCB mounting conditions. The device operates up to 150 °C junction temperature, supporting reliable use in enclosed power supplies without forced airflow.

Key Specifications

Parameter	Value and Actual Design Meaning
V_R	240 V - Maximum continuous reverse voltage before breakdown; enables use in 190–220 VAC-derived DC rails with safety margin.
I_F(AV)	400 mA - Average forward current at T_case = 75 °C; defines steady-state power delivery capability in continuous conduction mode.
V_F @ 400 mA	0.55 V typical - Forward voltage drop determines conduction loss (P_cond ≈ 220 mW); lower than silicon PN diodes.
T_j max	150 °C - Maximum allowable junction temperature; sets thermal derating limits for ambient and board-level cooling design.
R_thJA	350 K/W - Junction-to-ambient thermal resistance on standard 2-layer FR4; used to calculate ΔT_j = P_diss × R_thJA.
Package	SOT-23 - Surface-mount 3-pin plastic package; footprint compatible with automated pick-and-place and reflow soldering.

Pinout & Package

SOT-23 package with gull-wing leads; standardized 3-terminal configuration where Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = Not connected (NC) - confirmed per Infineon BAT240A datasheet Rev. 2.0 (2021).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Anode	Forward current entry point; connects to higher-potential node (e.g., transformer secondary or switch node).
Pin 2	Cathode	Forward current exit point; connects to output capacitor or ground return path in buck/flyback topologies.
Pin 3	No Connection	Internally isolated terminal; must remain unconnected to avoid parasitic coupling or mechanical stress.

Key Features

Feature	Design Value
Low forward voltage	0.55 V @ 400 mA reduces conduction loss by ~40% vs. comparable 1N5819-class silicon diodes.
High reverse voltage rating	240 V V_R supports universal-input offline SMPS designs without series stacking.
SOT-23 package	Enables compact layout in space-constrained AC/DC adapters and IoT power modules.
Junction temperature limit	150 °C rating allows operation in sealed enclosures with ambient up to 70 °C under full load.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay SS24-E3/57T	40 V V_R, 2 A I_F(AV), 0.5 V V_F - lower voltage rating, higher current capacity.	Not suitable for >45 V reverse stress; limited to low-voltage DC/DC converters.	Select only when system V_R < 40 V and I_F > 400 mA required.
ON Semiconductor SB240-E3/54	40 V V_R, 2 A I_F(AV), 0.52 V V_F - same voltage limitation, slightly lower V_F.	Incompatible with 100–240 VAC-derived rails due to insufficient reverse blocking.	Prefer for cost-sensitive 5–12 V output stages where 240 V rating is unnecessary.

Compared with BAT240AE6327HTSA1, SS24-E3/57T and SB240-E3/54 offer higher current but fail to meet 240 V reverse voltage requirements - making them unsuitable replacements in universal-input offline power supplies, though viable in low-voltage embedded systems.

FAQ

Is BAT240AE6327HTSA1 a silicon carbide (SiC) or gallium nitride (GaN) device?

No. BAT240AE6327HTSA1 is a silicon-based Schottky diode with a platinum-silicide (PtSi) anode. It does not use SiC or GaN materials. Its 240 V rating is achieved through optimized silicon doping and junction design, not wide-bandgap semiconductors.

Can BAT240AE6327HTSA1 replace a 1N5819 in a 12 V buck converter?

Yes, but only if reverse voltage stress remains below 40 V. BAT240AE6327HTSA1 has higher V_R (240 V) than 1N5819 (40 V), but its V_F (0.55 V) is comparable. In 12 V designs, it offers no efficiency benefit and costs more - 1N5819 remains optimal unless transient overvoltage protection is needed.

What is the maximum allowable PCB copper area for thermal improvement?

Per Infineon's datasheet, doubling the standard 1 cm² copper pad (2-layer FR4) reduces R_thJA from 350 K/W to ~220 K/W. Adding 2 cm² thermal pads on both sides with 4 thermal vias lowers it further to ~180 K/W - enabling 500 mA continuous current at 75 °C ambient.

Does BAT240AE6327HTSA1 have a specified reverse recovery time (t_rr)?

No - Schottky diodes like BAT240AE6327HTSA1 exhibit no minority-carrier storage, so t_rr is effectively zero. Datasheets omit t_rr specification because reverse recovery is limited only by junction capacitance discharge (typically < 10 ns), not carrier recombination.
