Product details
Overview
BAS40E6327HTSA1 from Infineon Technologies is a silicon Schottky diode optimized for high-speed switching, voltage clamping, and RF signal mixing in compact consumer and industrial electronics. It features 40 V reverse voltage rating, 120 mA forward current, 3–5 pF junction capacitance at 0 V, 10 Ω differential forward resistance at 10 mA, and operates across –55 °C to +150 °C.
For engineers reviewing the BAS40E6327HTSA1 datasheet, BAS40E6327HTSA1 pinout, BAS40E6327HTSA1 application, or BAS40E6327HTSA1 equivalent, key selection criteria include low forward voltage (250–600 mV at 1–40 mA), fast recovery time (<100 ps), ESD-sensitive handling requirements, and SOD323 package thermal limits (TS ≤ 81 °C).
Technical Context
This Schottky diode leverages a low-barrier metal-semiconductor junction to achieve sub-100 ps charge carrier lifetime and minimal forward voltage drop-critical for high-frequency detector and clamp circuits. Its 3–5 pF capacitance at 0 V and 10 Ω dynamic resistance support stable RF performance up to several hundred MHz.
The device is rated for 40 V DC blocking and 200 mA non-repetitive surge current, with thermal resistance RthJS ≤ 275 K/W (SOD323 package). It complies with AEC-Q101 for automotive-grade reliability but excludes BAS40-02L variants.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | Lower VR (30 V), higher IF (200 mA), same SOD-123 package | Not AEC-Q101 qualified; unsuitable for automotive underhood use | Prefer for cost-sensitive industrial power rails where 40 V margin is unnecessary |
| 1N5711 | Higher VF (430 mV @ 10 mA), larger DO-35 glass package, no RoHS compliance | Limited to prototyping and legacy repair due to through-hole mounting and Pb content | Select only when SOD323 footprint compatibility is not required and legacy stock exists |
Compared with NSR0230HT1G and 1N5711, BAS40E6327HTSA1 uniquely balances AEC-Q101 qualification, SOD323 miniaturization, 40 V robustness, and sub-350 mV VF at 10 mA-making it optimal for space-constrained automotive and portable RF designs.

FAQ
Is BAS40E6327HTSA1 suitable for automotive applications?
Yes. It is qualified to AEC-Q101 standards and rated for operation from –55 °C to +150 °C. Its SOD323 package supports reflow soldering, and its 40 V reverse voltage withstands load-dump transients in 12 V vehicle systems. Thermal resistance (RthJS ≤ 275 K/W) ensures reliability under sustained 120 mA conduction at board temperatures up to 81 °C.
What is the maximum allowable soldering temperature for BAS40E6327HTSA1?
The SOD323 package is rated for standard lead-free reflow profiles. Peak soldering temperature must not exceed 260 °C for ≤ 30 seconds, with ramp rates limited to ≤ 3 °C/s pre-peak and ≤ 6 °C/s post-peak. Exceeding these limits risks delamination or bond wire damage, especially given its ESD-sensitive structure.
How does BAS40E6327HTSA1 compare to BAS40-06W?
BAS40E6327HTSA1 uses the SOD323 package (TS ≤ 81 °C), while BAS40-06W uses SOT323 (TS ≤ 56 °C). Both share identical electrical specs (40 V VR, 120 mA IF, 3–5 pF CT), but the SOD323 offers superior thermal performance and smaller footprint-critical for dense PCB layouts in portable devices.
Can BAS40E6327HTSA1 be used in series or parallel configurations?
Series connection is viable for increased voltage blocking (e.g., two in series = 80 V), but requires matched VF to avoid imbalance. Parallel use is discouraged due to thermal runaway risk-its positive temperature coefficient of VF is insufficient to ensure current sharing without external balancing resistors.
