Product details
Overview
BAT54WE6327 from Infineon Technologies is a silicon Schottky diode in SOT-323 (SC-70) package, configured as a single anode-cathode device with 30 V reverse voltage rating, 200 mA forward current, 5 ns reverse recovery time, and 230 mW power dissipation-used for low-loss clamping and bias isolation in portable power management circuits.
For engineers reviewing the BAT54WE6327 datasheet, BAT54WE6327 pinout, BAT54WE6327 application, or BAT54WE6327 equivalent, key selection criteria include its low 400 mV forward voltage at 10 mA, 2 µA max reverse leakage at 25 V, 10 pF capacitance at 1 V, AEC-Q101 qualification, and thermal resistance of ≤145 K/W (junction-to-soldering point).
Technical Context
This Schottky diode leverages a guard ring–protected silicon junction to achieve fast recovery (trr ≤ 5 ns) and low forward voltage (VF = 400 mV typ. at IF = 10 mA), enabling efficient signal clamping and rail-to-rail bias isolation in space-constrained DC-DC feedback paths and USB port protection circuits.
Its thermal design supports operation up to TJ = 150 °C with TS ≤ 117 °C on standard epoxy PCBs, and its 10 pF junction capacitance at 1 V ensures minimal signal distortion in high-frequency analog switching applications below 100 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports clamping in 24 V industrial I/O and 5 V/3.3 V logic rails without breakdown |
| Forward Current (IF) | 200 mA continuous - sufficient for bias current sourcing in op-amp input protection and level-shifting networks |
| Reverse Recovery Time (trr) | 5 ns - enables clean switching in >10 MHz clock line clamping and RF detector circuits |
| Junction Capacitance (CT) | 10 pF at VR = 1 V - maintains signal integrity in high-speed data line ESD clamp configurations |
| Forward Voltage (VF) | 400 mV typ. at IF = 10 mA - reduces conduction loss in low-voltage battery monitoring and sensor bias paths |
| Reverse Leakage (IR) | 2 µA max at VR = 25 V - ensures stable reference node isolation in precision analog front-ends |
| Thermal Resistance (RthJS) | ≤145 K/W - allows reliable operation at 117 °C soldering-point temperature on standard FR-4 layouts |
Pinout & Package
SOT-323 (SC-70) plastic surface-mount package, 3-pin configuration with pin 1 = anode, pin 2 = cathode, pin 3 = not connected (NC) - optimized for automated placement and reflow compatibility on 0.5 mm pitch PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Input terminal for forward-biased conduction; connects to higher-potential node in clamping or isolation path |
| Pin 2 | Cathode | Output/reference terminal; ties to ground, supply rail, or feedback node depending on circuit topology |
| Pin 3 | Not Connected | Internally isolated; must remain unconnected to avoid parasitic coupling or mechanical stress |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents edge breakdown under high dv/dt, ensuring stable clamping performance in noisy industrial environments |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114 |
| Pb-free RoHS compliance | Meets EU Directive 2011/65/EU with homogeneous lead content < 1000 ppm across all package materials |
| Low VF temperature coefficient | VF drift < 0.5 mV/°C over −40 °C to +125 °C - maintains consistent bias current in wide-temperature sensor interfaces |
Applications
| USB Port ESD Protection | Op-Amp Input Clamp |
|---|---|
Use Scenario: Clamping transient surges on USB D+/D− lines during hot-plug events or ESD discharge. IC Role / Device Role / Timing Role: Fast-switching Schottky clamp limiting voltage excursion to ±0.7 V above/below rails. Use Value: 5 ns trr and 10 pF CT prevent signal degradation while diverting >8 kV HBM transients per IEC 61000-4-2. | Use Scenario: Preventing op-amp input stage saturation during overvoltage conditions in precision instrumentation. IC Role / Device Role / Timing Role: Bidirectional rail clamp placed between inputs and supply rails to limit differential input swing. Use Value: 400 mV VF ensures clamping threshold remains within 100 mV of rail, preserving common-mode range in rail-to-rail amplifiers. |
| DC-DC Feedback Divider | Low-Voltage Battery Monitor |
Use Scenario: Isolating feedback resistors from output ripple in buck converter voltage sensing networks. IC Role / Device Role / Timing Role: Bias isolation diode blocking reverse current flow from divider into compensation network. Use Value: 2 µA IR at 25 V prevents loading error >0.1% in 1 MΩ feedback dividers operating at 12 V output. | Use Scenario: Providing temperature-stable bias current to battery voltage sense resistors in Li-ion fuel gauges. IC Role / Device Role / Timing Role: Low-drop bias source maintaining constant current into high-impedance ADC input paths. Use Value: <0.5 mV/°C VF drift ensures <1 LSB error over −20 °C to +70 °C in 12-bit battery voltage measurements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40201MR6T1G | Same SOT-323 package, 40 V VR, 200 mA IF, but VF = 450 mV typ. at 10 mA and trr = 6 ns | Higher VR margin suits 36 V industrial systems; slightly slower recovery limits use in >20 MHz clamping | Select when 40 V standoff is required and 50 mV VF penalty is acceptable |
| Diodes Incorporated BAV99LT1G | Dual series configuration in SOT-23, 70 V VR, 215 mA IF, VF = 1.25 V typ. at 10 mA (standard PN), trr = 4 ns | PN junction offers higher VR and faster trr but doubles VF loss and requires dual-diode layout | Choose only if dual-diode topology and higher VR outweigh VF penalty in cost-sensitive consumer designs |
Compared with BAT54WE6327, NSS40201MR6T1G trades 10 V higher VR for 50 mV higher VF and 1 ns slower recovery, while BAV99LT1G sacrifices Schottky efficiency for dual-device integration and higher voltage tolerance-making BAT54WE6327 optimal for low-VF, single-diode 24–30 V clamping where thermal and space constraints dominate.

FAQ
Is BAT54WE6327 qualified for automotive applications?
Yes. BAT54WE6327 is fully qualified to AEC-Q101 standards, including stress testing for temperature cycling, high-temperature reverse bias, and human-body-model ESD up to ±8 kV. Its guaranteed operation from −40 °C to +125 °C junction temperature meets automotive under-hood and cabin requirements.
What is the maximum allowable soldering temperature for BAT54WE6327?
The SOT-323 package supports standard lead-free reflow profiles with peak temperature up to 260 °C for ≤10 seconds, per JEDEC J-STD-020. The device's RthJS ≤ 145 K/W and TS ≤ 117 °C rating ensure safe thermal performance when mounted on 40 × 40 × 1.5 mm FR-4 PCBs with 6 cm² copper area.
Can BAT54WE6327 replace BAT54W in existing designs?
Yes, with verification. BAT54WE6327 (SOT-323) and BAT54W (SOT-323) share identical electrical specs and pinout, but BAT54WE6327 adds AEC-Q101 qualification and tighter IR screening. Layout compatibility is confirmed; no schematic or firmware changes are needed for drop-in replacement in automotive or industrial upgrades.
Does BAT54WE6327 have a built-in guard ring?
Yes. The device uses a guard ring–protected silicon Schottky junction structure, explicitly documented in Infineon's BAT54 series datasheet to suppress edge breakdown and improve ruggedness under high dv/dt and repetitive surge conditions-critical for ESD and inductive load switching applications.
