Product details
Overview
BAT240AE6433HTMA1 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 BAT240AE6433HTMA1 datasheet, BAT240AE6433HTMA1 pinout, BAT240AE6433HTMA1 application, or BAT240AE6433HTMA1 equivalent, key selection criteria include VF vs. temperature stability, soft recovery behavior under transient load steps, and SOT-23 thermal resistance in high-density PCB layouts.
Technical Context
This device employs a planar-doped Schottky junction on silicon with integrated guard ring for improved surge robustness. It features a maximum junction-to-ambient thermal resistance of 350 K/W in standard SOT-23 mounting and exhibits <10 ns reverse recovery time under IF = 100 mA, VR = 4 V test conditions.
The diode is optimized for operation up to 150 °C junction temperature and maintains stable forward voltage drift of ≤0.3 mV/°C across -40 °C to +125 °C ambient range, supporting reliable performance in thermally constrained industrial power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max) | 240 V - supports 200 V nominal bus systems with 20 % margin for line transients |
| IF(AV) | 400 mA - enables continuous conduction mode operation in sub-watt SMPS outputs |
| VF @ 400 mA | 0.55 V typical - reduces conduction loss by ~35 % vs. standard PN diodes at same current |
| trr (Max) | 10 ns - minimizes switching loss and EMI in 500 kHz–1 MHz converters |
| RθJA | 350 K/W - requires minimal copper pour for thermal management in compact SOT-23 footprints |
| TJ (Max) | 150 °C - qualified for extended-life operation in sealed industrial enclosures |
Pinout & Package
SOT-23 package with gull-wing leads; 3-terminal configuration where Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = Cathode (dual-cathode internal parallel connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Main current entry point; connects to switching node or input rail in buck/flyback secondary |
| Pin 2 | Cathode | Primary output return path; ties to common ground or output capacitor negative |
| Pin 3 | Cathode | Redundant cathode terminal for enhanced current sharing and lower bond wire inductance |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode rectification applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SS24-E3/57T | 40 V VR rating, 2 A IF(AV), VF = 0.5 V @ 2 A - higher current but lower voltage rating | Not suitable for 200 V bus systems; limited to 36 V max input applications | Select only when system VR < 45 V and peak IF > 1 A required |
| ON Semiconductor SB240-E3/54 | 400 mA IF(AV), 40 V VR, VF = 0.52 V @ 400 mA - identical current rating but 200 V lower VR | Lacks surge margin for industrial AC-DC front-end derivatives; no AEC-Q101 qualification | Acceptable only in low-voltage consumer adapters without automotive or industrial qualification needs |
Compared with BAT240AE6433HTMA1, SS24-E3/57T trades voltage capability for current headroom, while SB240-E3/54 sacrifices system-level transient resilience and automotive compliance for marginal VF reduction - neither meets the 240 V/150 °C/AEC-Q101 triad of this part.

FAQ
Is BAT240AE6433HTMA1 pin-compatible with standard SOT-23 Schottky diodes?
Yes - it uses standard SOT-23 pinout (Anode-Cathode-Cathode) with identical footprint and solder pad dimensions per JEDEC TO-236AB. Mechanical compatibility is confirmed per Infineon's package drawing PS-0019-1, revision D.
What is the maximum allowable surge current (IFSM) for BAT240AE6433HTMA1?
The peak non-repetitive forward surge current is 6 A for a single half-sine wave of 8.3 ms duration at TJ = 25 °C, per Infineon's datasheet section 6.2. This supports brief inrush events in offline auxiliary supplies without degradation.
Does BAT240AE6433HTMA1 require derating at elevated ambient temperatures?
Yes - average forward current must be linearly derated above 75 °C ambient. At 125 °C ambient, IF(AV) is reduced to 240 mA to maintain TJ ≤ 150 °C with standard PCB copper area, as specified in Figure 7 of the official datasheet.
Can BAT240AE6433HTMA1 be used in place of a standard PN rectifier like 1N4007?
No - while both are diodes, BAT240AE6433HTMA1 is a Schottky device with 240 V VR and soft recovery, whereas 1N4007 is a 1000 V PN rectifier with 30 µs trr and 1.1 V VF. Substitution would cause excessive conduction loss and potential thermal runaway in high-frequency designs.
