Product details
Overview
BAT165E6327HTSA1 from Infineon Technologies is a medium-power Schottky diode configured as a single discrete device for low-loss rectification and fast-recovery clamping. It delivers 750 mA forward current, 40 V reverse voltage rating, and 0.44 V forward voltage at 750 mA, with 8.4 pF capacitance at 10 V/1 MHz - optimized for meter protection, bias isolation, and signal clamping in automotive and industrial sensor front-ends.
For engineers reviewing the BAT165E6327HTSA1 datasheet, BAT165E6327HTSA1 pinout, BAT165E6327HTSA1 application, or BAT165E6327HTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, SOD323 package thermal resistance (≤95 K/W), low VF at high IF, IR < 12 µA at 30 V, and ESD-sensitive handling requirements.
Technical Context
This Schottky diode leverages platinum-silicide (PtSi) barrier technology to achieve low forward voltage drop and fast switching without minority-carrier storage delay. Its junction temperature limit of 150 °C and derated VR/IF curves support operation up to 125 °C ambient in PCB-mounted configurations with RthJS ≤ 95 K/W.
The device exhibits nonlinear capacitance (CT = 8.4–12 pF at 10 V, decreasing with VR), sub-µA reverse leakage (<50 µA at 40 V/65 °C), and pulsed surge capability (IFSМ = 2.5 A, tp ≤ 10 ms), making it suitable for transient suppression and precision analog signal path protection where recovery time and conduction loss are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - maximum DC blocking capability before breakdown; derates linearly above 25 °C ambient |
| Forward Current (IF) | 750 mA - continuous DC forward conduction limit at TA = 25 °C |
| Forward Voltage (VF) | 0.44 V at IF = 750 mA - enables <0.33 W conduction loss in 750 mA paths |
| Reverse Current (IR) | ≤12 µA at VR = 30 V, 25 °C - ensures minimal leakage in high-impedance bias networks |
| Diode Capacitance (CT) | 8.4 pF at VR = 10 V, f = 1 MHz - supports >100 MHz signal clamping with low capacitive loading |
| Junction Temp (Tj) | 150 °C - defines maximum allowable die temperature under power dissipation and thermal design |
| Thermal Resistance (RthJS) | ≤95 K/W - enables thermal modeling from junction to solder point on standard FR4 PCB |
Pinout & Package
Package: SOD323 - surface-mount plastic case, 2.5 mm × 1.35 mm × 0.9 mm, cathode marked with white band and laser "C".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry terminal during forward conduction | Connected to lower-potential node in clamping or bias isolation; requires low-inductance trace routing |
| Cathode (Pin 2) | Current exit terminal; marked with white band and "C" | Connected to reference or higher-potential rail; serves as clamp return path or bias sink |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements (HTOL, TC, HTRB, etc.) |
| Pb-free / RoHS compliant | Meets EU Directive 2011/65/EU; no lead content in termination or molding compound |
| ESD sensitive (HBM Class 3B) | Requires handling per ANSI/ESDA S20.20; max 8 kV human-body model withstand |
| Low VF at high IF | 0.35 V typ. at 250 mA enables >92% efficiency in 3.3 V supply rail clamping |
| Fast recovery (no storage delay) | Zero minority-carrier lifetime yields <1 ns reverse recovery time - eliminates ringing in kHz–MHz switching |
Applications
| Meter Protection Circuit | Automotive Sensor Bias Isolation |
|---|---|
Use Scenario: Protects ADC input stages in smart electricity meters from line transients and ESD events. IC Role / Device Role: Clamping diode shunting overvoltage to rail while maintaining low leakage below 30 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | VF = 0.33 V @ 100 mA; IR = 2 µA @ 30 V; SOD-323 package; not AEC-Q101 qualified | Lacks automotive qualification; lower leakage but higher VF at >200 mA | Select when cost sensitivity outweighs AEC-Q101 requirement and IF remains <200 mA |
| BAT54CW | VF = 0.32 V @ 100 mA; IR = 1 µA @ 30 V; SOT-323 package; AEC-Q101 qualified | Same qualification level but larger SOT-323 footprint; 0.1 mm height difference affects board clearance | Choose when PCB layout allows SOT-323 and tighter IR spec is prioritized over thermal resistance |
Compared with SBAT54LT1G and BAT54CW, BAT165E6327HTSA1 offers superior thermal resistance (≤95 K/W vs. ≥120 K/W), higher IF rating (750 mA vs. 200–300 mA), and optimized VF/IR trade-off for sustained 500–750 mA clamping - making it preferred for thermally constrained automotive and industrial metering designs.

FAQ
Is BAT165E6327HTSA1 suitable for 125 °C ambient operation?
Yes - its Tj limit is 150 °C and derating curves confirm VR = 30 V and IF = 500 mA remain valid at TA = 125 °C when mounted on PCB with RthJS ≤ 95 K/W. Thermal simulation using the provided RthJS value is required to verify junction temperature margin.
What is the cathode marking convention for BAT165E6327HTSA1?
The cathode is identified by a white band near Pin 2 and a laser-marked "C" on the top surface of the SOD323 package. The marking layout matches Infineon's standard SOD323 footprint with 0.8 mm pad width and 2.5 mm center-to-center pitch.
Does BAT165E6327HTSA1 require special ESD handling during assembly?
Yes - it is classified as ESD-sensitive (HBM Class 3B, 8 kV). Assembly must follow ANSI/ESDA S20.20: use grounded workstations, ionizers, conductive flooring, and wrist straps; avoid contact with bare pins prior to soldering.
Can BAT165E6327HTSA1 replace BAT54 in existing designs?
Only with validation - BAT165E6327HTSA1 has higher IF (750 mA vs. 200 mA), higher VF at low current (0.23 V vs. 0.2 V @ 10 mA), and different thermal resistance. Layout and thermal performance must be rechecked; AEC-Q101 qualification adds value only if automotive compliance is required.
