Product details
Overview
BAT6402WH6327XTSA1 from Infineon Technologies is a silicon Schottky diode in SCD80 (SOT-23 variant) package, configured as a single anode-cathode device with 40 V reverse voltage rating, 250 mA forward current capability, and 5 ns reverse recovery time. It delivers low forward voltage (310 mV typ. at 10 mA) and 4 pF capacitance at 1 V for high-speed clamping and bias isolation in automotive sensor signal conditioning.
For engineers reviewing the BAT6402WH6327XTSA1 datasheet, BAT6402WH6327XTSA1 pinout, BAT6402WH6327XTSA1 application, or BAT6402WH6327XTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, thermal resistance of ≤115 K/W (junction-to-soldering point), and ESD-sensitive handling requirements per IEC 61000-4-2 Level 3.
Technical Context
This Schottky diode uses a planar silicon process with integrated diffused guard ring to suppress edge breakdown and ensure stable reverse leakage (<2 µA at 30 V, 25°C). Its low series inductance (0.6 nH) and minimal junction capacitance support RF and fast-switching applications up to ~500 MHz.
The device operates across –55°C to +150°C junction temperature range and is rated for 800 mA non-repetitive surge current (10 ms), making it suitable for transient protection in low-voltage analog front-ends where thermal management is constrained by PCB layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports bias isolation in 24 V automotive systems with margin against load-dump transients |
| Forward Current (IF) | 250 mA - enables continuous operation in low-power sensor bias networks without heatsinking |
| Reverse Recovery Time (trr) | 5 ns - ensures minimal switching loss and ringing in >10 MHz clamping circuits |
| Forward Voltage (VF) | 310 mV typ. at 10 mA - reduces power loss and self-heating in battery-powered metering circuits |
| Diode Capacitance (CT) | 4 pF at 1 V, 1 MHz - preserves signal integrity in RF detector and antenna switch applications |
| Junction-to-Soldering Point RthJS | ≤115 K/W - allows direct PCB copper pour thermal coupling for sustained 200 mA operation at TS ≤ 121°C |
Pinout & Package
Package: SCD80 (pin-compatible with SOT-23 but optimized for lower inductance and improved thermal performance; 1.7 mm × 0.8 mm footprint, cathode marked with bar on terminal 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary current entry point; connects to supply rail or signal source in clamp/bias configurations |
| 2 | Cathode | Current exit path; marked with cathode bar; ties to ground or reference node for unidirectional conduction |
| 3 | Not connected | No internal connection; electrically isolated; used for mechanical anchoring and thermal dissipation via exposed pad |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use including temperature cycling, humidity, and mechanical shock |
| Integrated diffused guard ring | Prevents premature edge breakdown at VR = 40 V, enabling stable leakage <2 µA over life |
| Pb-free RoHS-compliant packaging | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260°C) |
| Low series inductance (LS) | 0.6 nH - minimizes voltage overshoot during fast di/dt events in ESD protection paths |
Applications
| Automotive Sensor Signal Clamping | Portable Meter Bias Isolation |
|---|---|
Use Scenario: Protecting LIN bus transceiver inputs from ±30 V ESD and load-dump spikes in body control modules. IC Role / Device Role: Fast clamping diode shunting transients to ground while preserving DC bias integrity. Use Value: 5 ns trr and 4 pF CT prevent signal distortion during 10–100 ns transients; AEC-Q101 ensures field reliability. | Use Scenario: Isolating precision ADC reference voltage from noisy microcontroller supply rails in handheld multimeters. IC Role / Device Role: Low-VF Schottky barrier blocking reverse current while minimizing offset error. Use Value: 310 mV VF at 10 mA limits reference rail droop to <0.3 mV, maintaining 16-bit measurement accuracy. |
| RF Detector Diode | Low-Power Logic-Level Translation |
Use Scenario: Demodulating 433 MHz ASK signals in TPMS receiver front-ends. IC Role / Device Role: Zero-bias envelope detector leveraging low CT and fast trr for high-frequency rectification. Use Value: 4 pF CT enables >500 MHz bandwidth; 0.6 nH LS avoids resonance with PCB trace inductance. | Use Scenario: Level-shifting 1.8 V GPIO outputs to 3.3 V I²C pull-up domain in wearables. IC Role / Device Role: Passive bidirectional level translator using Schottky forward drop asymmetry. Use Value: 310 mV VF provides predictable 1.8 V → 3.3 V translation window; 250 mA IF handles bus contention currents. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAR63-02W | Same SCD80 package, 30 V VR, 250 mA IF, 3 ns trr, 0.6 nH LS | Lower VR rating limits use in 24 V systems; faster trr benefits higher-frequency RF detection | Select when VR margin <10 V suffices and sub-3 ns recovery is critical |
| NSR0230HT1G | SOD-523 package, 30 V VR, 200 mA IF, 4 ns trr, 5 pF CT | Smaller footprint but higher RthJS (250 K/W); less robust thermal performance at >150 mA | Choose for space-constrained portable designs where peak IF ≤ 150 mA |
Compared with BAR63-02W and NSR0230HT1G, BAT6402WH6327XTSA1 offers superior VR margin for 24 V automotive systems and lower thermal resistance than SOD-523 alternatives-critical for sustained bias current in thermally dense modules.

FAQ
Is BAT6402WH6327XTSA1 suitable for ESD protection per IEC 61000-4-2?
Yes-it is explicitly rated for ESD-sensitive handling and tested to withstand contact discharge up to ±8 kV (Level 3) when implemented with proper PCB layout (short traces, ground plane coupling). Its 5 ns trr and low CT enable effective clamping of fast ESD pulses without signal degradation.
What is the maximum continuous forward current at 105°C ambient?
At TA = 105°C with standard PCB mounting (1 cm² 1 oz Cu), the maximum continuous IF is 180 mA. This derives from the specified TS ≤ 121°C limit and RthJS ≤ 115 K/W, allowing 16°C temperature rise above ambient before reaching the 121°C soldering-point limit.
Does the SCD80 package require special reflow profile considerations?
Yes-the SCD80 is RoHS-compliant and qualified for lead-free reflow with peak temperature up to 260°C for ≤10 seconds. Preheat ramp rate must not exceed 3°C/s, and time above 220°C should be limited to 60–90 seconds to avoid delamination or marking degradation.
Can BAT6402WH6327XTSA1 replace BAT64-02W in existing designs?
Yes-BAT6402WH6327XTSA1 is the tape-and-reel packaged version of BAT64-02W (same die, same SCD80 package, identical electrical specs). The "H6327" suffix denotes 8,000-piece reel packaging per JEDEC standard; no layout or schematic changes are needed.
