Product details
Overview
BAT6405WE6327HTSA1 from Infineon Technologies is a silicon Schottky diode in SCD80 package configured as a common cathode dual diode, rated for 40 V reverse voltage, 250 mA forward current, and 5 ns reverse recovery time, used for low-loss clamping and bias isolation in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT6405WE6327HTSA1 datasheet, BAT6405WE6327HTSA1 pinout, BAT6405WE6327HTSA1 application, or BAT6405WE6327HTSA1 equivalent, key selection criteria include its 4 pF capacitance at 1 V, 370 mV typical forward voltage at 30 mA, AEC-Q101 qualification, RoHS-compliant lead-free construction, and thermal resistance of 155 K/W (junction-to-soldering point).
Technical Context
This dual common-cathode Schottky diode integrates a diffused guard ring to suppress edge breakdown and supports fast switching with sub-5 ns trr. Its low VF (370 mV typ. @ 30 mA) and low CT (4 pF @ 1 V) enable high-efficiency clamping in precision analog front-ends.
The device operates across –55 °C to +150 °C junction temperature range and is qualified per AEC-Q101 for automotive use. Thermal design must account for RthJS = 155 K/W and derated IF vs. TS curves specific to the BAT64-05W variant.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAR63-02W | Single diode, SOT-23, VF = 390 mV @ 30 mA, CT = 0.6 pF | Limited to single-channel clamping; lower capacitance but no dual-anode convenience | Select when only one clamping path is needed and ultra-low CT (<1 pF) is prioritized over dual functionality |
| BAT54CW | Common-cathode dual, SOT-323, VF = 380 mV @ 30 mA, CT = 10 pF | Higher capacitance limits use in >10 MHz signal paths; smaller footprint but higher thermal resistance | Choose for cost-sensitive consumer designs where 10 pF CT is acceptable and board space is constrained |
Compared with BAR63-02W and BAT54CW, BAT6405WE6327HTSA1 uniquely balances dual-channel capability, 4 pF capacitance, 155 K/W thermal resistance, and AEC-Q101 compliance-making it optimal for automotive-grade dual-signal protection where space, speed, and reliability are jointly critical.

FAQ
What is the marking code for BAT6405WE6327HTSA1?
The device is laser-marked "65s" on the top surface of the SCD80 package, indicating the BAT64-05W variant. This marking aligns with Infineon's standardized coding for common-cathode dual Schottky diodes in the BAT64 family and is visible under 10× magnification.
Is BAT6405WE6327HTSA1 suitable for 125 °C ambient operation?
Yes - with proper PCB copper pour and thermal vias, the device supports 125 °C ambient via its 155 K/W RthJS and 150 °C Tj limit. Derating curves in the datasheet confirm ≥150 mA IF at TS = 125 °C, making it viable for under-dash automotive modules.
Does this part have integrated ESD protection?
No - BAT6405WE6327HTSA1 is an ESD-sensitive device (per datasheet warning), not an ESD-protected component. It requires external handling precautions and is typically paired with dedicated TVS diodes or RC filters for system-level ESD robustness.
How does the SCD80 package compare thermally to SOT-323?
The SCD80 package delivers RthJS = 155 K/W, significantly better than typical SOT-323 Schottky diodes (~250–300 K/W). Its larger pad area and optimized thermal path reduce junction temperature rise by up to 40 °C at 250 mA, improving long-term reliability in sealed enclosures.
