Product details
Overview
BAT54E6327HTSA1 from Infineon Technologies is a silicon Schottky diode in SOT-23 package configured as a single discrete device, with 30 V reverse voltage rating, 200 mA forward current, 5 ns reverse recovery time, 10 pF capacitance at 1 V, and 240–800 mV forward voltage across 0.1–100 mA load - used for low-loss clamping and bias isolation in portable power management circuits.
For engineers reviewing the BAT54E6327HTSA1 datasheet, BAT54E6327HTSA1 pinout, BAT54E6327HTSA1 application, or BAT54E6327HTSA1 equivalent, key selection criteria include its fast recovery (5 ns), low VF at light loads (240 mV @ 0.1 mA), AEC-Q101 qualification, guard ring protection, and thermal resistance of ≤245 K/W (junction-to-soldering point).
Technical Context
This Schottky diode leverages a planar silicon process with guard ring termination to suppress edge breakdown and ensure stable reverse leakage (<2 µA @ 25 V). Its low barrier height enables sub-0.3 V forward drop at microampere bias levels, supporting precision voltage clamping in signal path protection.
The device operates up to 150 °C junction temperature and exhibits minimal capacitance variation (≤10 pF @ 1 MHz, VR = 1 V), making it suitable for high-frequency clamp and RF detector applications where parasitic reactance must be tightly controlled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 30 V - defines maximum allowable DC or peak AC reverse bias before breakdown; sets clamping ceiling in overvoltage protection. |
| IF (Forward Current) | 200 mA - continuous DC current handling capability; determines usable current range in bias networks and level-shifters. |
| trr (Reverse Recovery Time) | 5 ns - ultrafast turn-off behavior; enables use in >10 MHz switching nodes without tail current losses. |
| VF @ 1 mA | 320 mV - low conduction loss at sensing/monitoring currents; critical for battery voltage monitoring accuracy. |
| CT @ 1 V, 1 MHz | 10 pF - small junction capacitance; minimizes signal distortion in RF detector and high-speed logic clamp circuits. |
| IR @ 25 V | 2 µA - low leakage ensures minimal standby current drain in always-on power rails and backup circuits. |
| RthJS | ≤245 K/W - thermal resistance from junction to soldering point; informs PCB copper area requirements for 230 mW power dissipation. |
Pinout & Package
SOT-23 plastic surface-mount package (3-pin, standard lead pitch 0.95 mm), rated for reflow soldering per JEDEC J-STD-020. Pin 1 = anode, Pin 2 = cathode, Pin 3 = cathode (common cathode configuration not applicable - BAT54E6327HTSA1 is single diode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Input terminal for forward conduction; connects to higher-potential node in clamp or isolation path. |
| Pin 2 | Cathode | Output/return terminal; ties to reference rail (e.g., VCC or GND) depending on clamping polarity. |
| Pin 3 | Cathode (SOT-23 internal tie) | Internally bonded to Pin 2 - electrically redundant; improves current sharing and thermal path to PCB pad. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Suppresses edge leakage and enhances voltage stability under high-field stress, improving long-term reliability in automotive environments. |
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements (HTOL, TC, ESD, etc.), enabling use in body control modules and infotainment power rails. |
| Pb-free / RoHS compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles and eliminates hazardous substance reporting obligations. |
| Low VF at µA–mA range | 240 mV @ 0.1 mA enables accurate low-current biasing in sensor interfaces and analog front-end protection without loading source impedance. |
Applications
| USB Port ESD Clamp | Automotive CAN Bus Bias Isolation |
|---|---|
Use Scenario: Clamps transient voltages on USB D+/D− lines during hot-plug or ESD events while preserving signal integrity. IC Role / Device Role: Low-capacitance (10 pF), fast-recovery (5 ns) Schottky clamp diode placed between data line and VBUS/GND. Use Value: Prevents damage to USB transceivers without distorting 480 Mbps signaling due to minimal parasitic capacitance and sub-nanosecond response. | Use Scenario: Isolates bias current between CANH/CANL differential pair and local 5 V supply in automotive gateway ECUs. IC Role / Device Role: Single Schottky diode providing unidirectional current blocking and low-loss DC path for common-mode bias network. Use Value: Enables stable 5 V bias injection into CAN bus while preventing backfeed into controller I/O, leveraging 30 V VR and <2 µA IR at 25 V. |
| Portable Device Battery Monitor Protection | RF Detector Input Stage |
Use Scenario: Protects ADC input of fuel gauge IC from overvoltage during battery insertion or charger fault conditions. IC Role / Device Role: Low-VF (240 mV @ 0.1 mA) Schottky clamp limiting voltage swing to ±0.3 V around reference. Use Value: Preserves measurement accuracy by avoiding forward conduction error in microampere-sensing paths, unlike higher-VF silicon diodes. | Use Scenario: Rectifies weak RF signals (e.g., 868 MHz ISM band) in low-power wireless sensor receivers. IC Role / Device Role: Zero-bias detector diode operating in square-law region with minimal series resistance and 10 pF CT. Use Value: Delivers usable DC output from sub-10 mV RMS RF inputs due to low barrier height and negligible junction capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54DW-7-F | Dual common-cathode configuration; 30 V VR, 200 mA IF, but trr = 6 ns and VF = 340 mV @ 1 mA. | Requires dual-diode layout; unsuitable for single-diode footprint replacement without board revision. | Select only when dual-channel clamping is needed and SOT-23-3 layout allows shared cathode routing. |
| NSR0230HT1G | Same SOT-23 package; 30 V VR, 200 mA IF, but VF = 370 mV @ 1 mA and CT = 12 pF @ 1 V. | Higher capacitance limits use above 500 MHz; slightly higher VF increases bias error in precision analog paths. | Acceptable for cost-sensitive industrial clamping where 12 pF and 370 mV VF are within system margin. |
Compared with SBAT54DW-7-F and NSR0230HT1G, BAT54E6327HTSA1 offers the lowest VF at microampere bias (240 mV @ 0.1 mA), tightest CT control (≤10 pF), and AEC-Q101 qualification - making it preferred for automotive signal integrity and battery-monitoring accuracy.

FAQ
Is BAT54E6327HTSA1 pin-compatible with BAT54W?
No. BAT54E6327HTSA1 uses standard SOT-23 with Pins 1 (anode), 2 (cathode), and 3 (cathode tie), while BAT54W is a single-diode variant in SOT-323 package with different pin spacing and thermal pad layout. Mechanical and soldering profiles are not interchangeable without PCB redesign.
What is the maximum allowable junction temperature during operation?
The absolute maximum junction temperature is 150 °C, as specified in Infineon's official datasheet. Operation beyond this limit risks irreversible degradation of the Schottky barrier and increased reverse leakage. Derating is required above 94 °C ambient when mounted on standard epoxy PCB (40 × 40 × 1.5 mm).
Does BAT54E6327HTSA1 support reflow soldering per JEDEC standards?
Yes. The device is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C for ≤30 seconds. Its Pb-free terminations and mold compound withstand standard Class 3 moisture sensitivity level (MSL3) handling when sealed per specification.
Can BAT54E6327HTSA1 be used in place of a 1N5711 for RF detection?
Yes - with advantages. BAT54E6327HTSA1 offers lower VF (240 mV vs. ~450 mV), faster trr (5 ns vs. ~50 ns), and smaller CT (10 pF vs. ~2 pF, but optimized for 1 MHz–1 GHz), making it superior for low-level RF rectification in modern ISM-band receivers where sensitivity and speed matter.
