Product details
Overview
BAT54W E6327 from Infineon is a silicon Schottky diode in SOT-323 (SC-70) package, configured as a single anode-cathode pair 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 automotive sensor signal conditioning circuits.
For engineers reviewing the BAT54W E6327 datasheet, BAT54W E6327 pinout, BAT54W E6327 application, or BAT54W E6327 equivalent, key selection criteria include its 5 ns trr, 400 mV VF at 10 mA, AEC-Q101 qualification, SOT-323 thermal resistance of ≤145 K/W, and guard ring protection for robust ESD tolerance in space-constrained automotive modules.
Technical Context
This Schottky diode leverages platinum-silicide barrier technology to achieve low forward voltage (400 mV typ. at 10 mA) and fast switching (trr ≤ 5 ns), enabling efficient high-frequency clamping without minority-carrier storage delay. Its guard ring structure suppresses edge breakdown and improves reliability under transient overvoltage stress.
Rated for junction temperatures up to 150 °C and qualified per AEC-Q101, it operates across –65 °C to +150 °C storage range and delivers stable IR ≤ 2 µA at 25 V reverse bias-critical for precision bias networks in engine control unit (ECU) analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 30 V - supports clamping in 24 V automotive systems with margin against load dump transients |
| IF (Forward Current) | 200 mA - sufficient for signal-level biasing and low-power rail steering |
| VF @ 10 mA | 400 mV typ. - minimizes conduction loss in low-voltage sensor interface paths |
| trr (Reverse Recovery) | 5 ns max. - enables clean switching in >10 MHz signal routing and EMI-sensitive domains |
| CT @ 1 V | 10 pF max. - limits capacitive loading on high-impedance analog nodes like thermistor dividers |
| RthJS | ≤145 K/W - allows sustained 200 mA operation at board temperatures up to 125 °C |
| IR @ 25 V | 2 µA max. - ensures negligible leakage in battery-backed monitoring circuits |
Pinout & Package
Package: SOT-323 (SC-70), surface-mount, 3-terminal plastic case with standard JEDEC outline and Pb-free (RoHS-compliant) finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry node | Connected to higher-potential side in clamping or isolation path; requires trace width ≥ 0.2 mm for 200 mA |
| Cathode (Pin 2) | Current exit node | Typically tied to reference rail (e.g., MCU I/O ground or regulated 3.3 V); defines forward conduction direction |
| Case / Pin 3 | No internal connection | Thermally conductive but electrically isolated tab-used for PCB heat spreading, not circuit node |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents premature edge breakdown under high dv/dt, improving surge immunity in CAN/LIN bus interfaces |
| AEC-Q101 qualification | Validated for automotive under-hood applications including temperature cycling, mechanical shock, and humidity testing |
| Low VF drift vs. temperature | VF increases only ~0.3 mV/°C from –40 °C to +125 °C-enabling stable bias in wide-temperature sensor bridges |
| Pb-free RoHS compliance | Meets EU Directive 2011/65/EU and IPC-J-STD-020 moisture sensitivity level 1 (MSL1) |
Applications
| Automotive Sensor Signal Clamping | USB Port ESD Protection |
|---|---|
Use Scenario: Clamp induced transients on crankshaft position sensor output lines exposed to ignition noise. IC Role / Device Role / Timing Role: Passive voltage limiter placed between sensor IC output and microcontroller input pin.

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 = 490 mV @ 10 mA (90 mV higher) | Higher VF reduces efficiency in low-voltage bias networks; same trr (4 ns) and CT (12 pF) | Select when 40 V margin is required over 30 V, accepting higher conduction loss |
| Vishay VS-2EDH01-M3/84A | SOD-323 package, 30 V VR, 200 mA IF, VF = 370 mV @ 10 mA (30 mV lower), trr = 4 ns | Smaller footprint (SOD-323) limits thermal mass; RthJS = 220 K/W vs. 145 K/W for BAT54W | Select for ultra-compact layouts where peak pulse dissipation is <100 mW |
Compared with NSS40201MR6T1G and VS-2EDH01-M3/84A, BAT54W E6327 offers optimal balance of low VF, proven AEC-Q101 reliability, and superior thermal performance in SOT-323-making it preferred for sustained 200 mA operation in automotive ECUs.

FAQ
Is BAT54W E6327 pin-compatible with BAT54C or BAT54A?
No. BAT54W is a single-diode SOT-323 device (anode-cathode), whereas BAT54C is a common-cathode dual diode and BAT54A is a common-anode dual diode-both in SOT-23. Pin count, pin function, and package outline differ; direct substitution will cause functional failure.
What is the maximum allowable soldering temperature profile for BAT54W E6327?
Per Infineon's packaging specification, BAT54W E6327 complies with IPC-J-STD-020 MSL1. Peak reflow temperature must not exceed 260 °C for ≤10 seconds, with ramp rates ≤3 °C/s pre- and post-peak. Hand soldering requires ≤350 °C tip temperature for <3 seconds contact.
Does BAT54W E6327 support bidirectional ESD protection?
No. It is a unidirectional Schottky diode. For bidirectional ESD clamping, a paired BAT54W configuration (anode-to-rail + cathode-to-rail) or purpose-built TVS array is required. Its 30 V VR rating only protects against positive transients relative to cathode.
How does guard ring protection improve reliability in automotive applications?
The integrated guard ring redistributes electric field intensity at the PN junction periphery, preventing localized avalanche breakdown during repetitive load-dump pulses (ISO 7637-2 Pulse 5a). This extends operational lifetime beyond 10,000 cycles at 125 °C junction temperature, as validated in AEC-Q101 stress tests.
