Product details
Overview
BAT5406WH6327XTSA1 from Infineon Technologies is a silicon Schottky diode in SOT-323 (SC-70) package configured as a common-anode dual diode, rated for 30 V reverse voltage, 200 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 BAT5406WH6327XTSA1 datasheet, BAT5406WH6327XTSA1 pinout, BAT5406WH6327XTSA1 application, or BAT5406WH6327XTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, 240 mV forward voltage at 0.1 mA, 10 pF capacitance at 1 V, thermal resistance of 145 K/W, and common-anode topology for dual-rail protection.
Technical Context
This dual Schottky diode integrates two anode-connected junctions in a single SOT-323 package, enabling simultaneous clamping of complementary signals without cross-coupling. Its guard ring structure ensures stable breakdown behavior and robust ESD immunity up to ±8 kV HBM.
The device operates with low forward voltage drop across its full rated current range (240–800 mV from 0.1–100 mA), and exhibits minimal capacitance variation (≤10 pF at 1 MHz, VR = 1 V), supporting high-frequency transient suppression in CAN FD and LIN bus interface protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage | 30 V - supports clamping in 24 V automotive systems with margin against load dump transients |
| Forward Current | 200 mA - sufficient for biasing and signal-level protection in sensor front-ends and level shifters |
| Reverse Recovery Time | 5 ns - enables effective high-speed transient suppression in digital I/O and communication lines |
| Forward Voltage @ 1 mA | 320 mV - minimizes power loss and self-heating in low-current bias networks |
| Diode Capacitance @ 1 V | 10 pF - preserves signal integrity in >10 MHz analog and digital interfaces |
| Junction Temperature | 150 °C - compatible with under-hood automotive environments per AEC-Q101 stress testing |
| Thermal Resistance RthJS | 145 K/W - allows sustained operation at 125 °C ambient when mounted on standard PCB copper area |
Pinout & Package
SOT-323 (SC-70) plastic surface-mount package, 3-terminal configuration with common anode (Pin 1 = Anode, Pins 2 & 3 = Cathodes).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (common) | Shared positive terminal for dual-diode conduction path; connects to supply rail or reference node |
| Pin 2 | Cathode 1 | First clamping path to ground or low-side reference; used for signal A protection |
| Pin 3 | Cathode 2 | Second independent clamping path; used for signal B or complementary rail protection |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents edge breakdown and improves long-term reliability under repetitive surge stress |
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensors |
| Pb-free / RoHS compliant | Meets EU Directive 2011/65/EU and JEDEC J-STD-020 reflow profile requirements |
| Low leakage current | IR ≤ 2 µA at 25 V reverse bias ensures minimal standby power drain in always-on circuits |
| Fast switching speed | 5 ns trr supports clamping of sub-100 ns transients in CAN, LIN, and I²C bus protection |
Applications
| Automotive Sensor Interface Protection | CAN FD Bus Clamping |
|---|---|
Use Scenario: Protecting analog outputs of pressure and temperature sensors in engine control modules from ISO 7637-2 pulse 5a/b transients. IC Role / Device Role / Timing Role: Dual common-anode Schottky clamp limiting input voltage swing to ±0.3 V beyond rails during fast overvoltage events. Use Value: Prevents op-amp saturation and ADC offset drift while maintaining <10 ns response latency due to 5 ns trr and low CT. |
Use Scenario: Bidirectional clamping of CAN_H and CAN_L lines in 5 Mbps CAN FD nodes against ESD and coupling noise. IC Role / Device Role / Timing Role: Common-anode configuration provides symmetrical rail-to-rail clamping without adding series impedance to differential pair. Use Value: Maintains signal integrity with <10 pF capacitance per diode and avoids timing skew between differential lines. |
| LIN Bus Transceiver Protection | Low-Power Microcontroller I/O Clamp |
Use Scenario: Safeguarding LIN transceiver inputs against battery disconnect spikes and load dump in body control units. IC Role / Device Role / Timing Role: Dual-path clamping to VBAT and GND using shared anode, reducing component count versus discrete solutions. Use Value: Enables single-device protection of both TX and RX pins with guaranteed 30 V standoff and 600 mA surge capability. |
Use Scenario: Isolating GPIO pins of ultra-low-power MCUs (e.g., Infineon XMC1000) from external switch bounce and relay coil kickback. IC Role / Device Role / Timing Role: Low-VF Schottky path shunts transient energy before internal ESD structures activate. Use Value: Reduces forward voltage overhead to 240 mV at 0.1 mA, preserving sleep-mode current budgets below 1 µA. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-anode 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 higher VF (420 mV @ 1 mA) and slower trr (10 ns) | Higher voltage margin suits 36 V industrial systems; less suitable for low-VF precision biasing | Select when system requires >30 V standoff and can tolerate higher conduction loss |
| Diodes Incorporated BAV99WQ-7-F | AEC-Q101 qualified, same topology, but 70 V VR, 215 mA IF, and 4 ns trr; VF = 350 mV @ 1 mA | Better high-speed performance and wider voltage range, yet larger junction capacitance (15 pF) | Preferred for CAN FD nodes requiring faster recovery and higher transient immunity |
Compared with BAT5406WH6327XTSA1, NSS40201MR6T1G trades lower VF for reduced speed and higher voltage rating, while BAV99WQ-7-F offers faster recovery and higher VR at the cost of increased capacitance-critical for high-frequency signal integrity.

FAQ
Is BAT5406WH6327XTSA1 pin-compatible with BAT54-06W?
Yes - BAT5406WH6327XTSA1 is the tape-and-reel packaging variant of BAT54-06W, sharing identical SOT-323 footprint, pin assignment (common anode), and electrical specifications. The "H6327" suffix denotes reel packaging per EIA-481, and "XTSA1" indicates Infineon's standard product marking code.
What is the maximum allowable soldering temperature for this device?
The device complies with JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C for 30 seconds. Hand-soldering must not exceed 350 °C for ≤3 seconds per joint to avoid delamination or bond wire damage.
Does this diode require external series resistance for ESD protection?
No - BAT5406WH6327XTSA1 is rated for ±8 kV HBM ESD per AEC-Q101, and its low dynamic impedance enables direct placement at I/O pads. External series resistance is only needed if system-level IEC 61000-4-2 (±15 kV contact) compliance is required, typically adding 10–100 Ω.
Can BAT5406WH6327XTSA1 replace BAT54W in a single-diode application?
No - BAT54W is a single-diode SOT-323 device, whereas BAT5406WH6327XTSA1 is a dual common-anode configuration. Using it in place of BAT54W would leave one cathode unconnected, increasing parasitic capacitance and potentially causing unintended conduction paths in high-impedance nodes.
